# MAX Alphabetic Parameter Reference

The MAX supports a variety of software loads which are customized to particular purposes. The installed software may not support all of the parameters described in this reference.

## A B C D E F G H I K L M N O P Q R S T U V W X Z

## Numeric

## 1st Line

Description: Enables or disables the first T1 or E1 line. If the line is disabled, the MAX drops existing connections and brings down the line.

Usage: Specify one of the following values:

- Queisced to set all inactive channels on that line to out_of_service state, as soon as the user saves the menu changes. When current calls on that line are ended, the associated channels will be put out of service. Selecting any other option after the Quiesced option restores all channels to in_service state, as soon as the user saves the menu.

- Disabled to disable the line.

- Trunk (the default) to enable line 1 to exchange signaling information over the interface.

- T-Online-USER

  This setting indicates that the line connects to the switch, allowing the user to dial in.

- T-Online-ZGR

  This setting indicates that the line connects to the ZGR server.

Example: 1st Line=Trunk

Dependencies: If you specify Quiesced, 2nd line cannot be D&I.

Location: `Net/T1 > Line Config, Net/E1 > Line Config`

See Also: Sig Mode

## 2nd Adrs

Description: Assigns a second IP address to the Ethernet interface. It gives the MAX a logical interface on two networks or subnets on the same backbone, a feature called dual IP.

Usage: Specify a valid IP address on the remote subnet. The default value is 0.0.0.0/0.

Example: 2nd Adrs=10.65.212.56/24

Location: `Ethernet > Mod Config > Ether Options`

See Also: IP Adrs

## 2nd Line

Description: Enables or disables the second T1 or E1 line and specifies whether it will support trunk calls or drop-and-insert applications only. Drop-and-insert applications are used to accept calls on line #1 and drop them through to line #2. It is typically used to drop voice calls through from line #1 to a PBX on line #2.

Usage: Specify one of the following values:

- Queisced to set all inactive channels on that line to out_of_service state, as soon as the user saves the menu changes. When current calls on that line are ended, the associated channels will be put out of service. Selecting any other option after the Quiesced option restores all channels to in_service state, as soon as the user saves the menu.

- Disabled to disable the line.

- Trunk (the default) to enable line 2 to exchange signaling information over the interface.

- D&I to use the second line for Drop-and-Insert applications only.

- T-Online-USER

  This setting indicates that the line connects to the switch, allowing the user to dial in.

- T-Online-ZGR

  This setting indicates that the line connects to the ZGR server.

Example: 2nd Line=Trunk

Dependencies: If you specify D&I, some channels on line 1 must also be set up for drop-and- insert. To support a PBX, the signaling mode must specify PBX. If you specify D&I, Line 1 cannot be set to Quiesced.

Location: `Net/T1 > Line Config, Net/E1 > Line Config`

See Also: Sig Mode, Ch N (N=1-24, 1-32)

## 3rd Prompt

Description: Specifies an optional third prompt for a terminal server login. If this value is null, no third prompt is displayed. If the connection is RADIUS-authenticated, the information entered by the user at the third prompt (up to 80 characters) is passed to the server as the value of the Ascend-Third-Prompt attribute. What the RADIUS server does with this information depends upon how the server is configured.

Usage: Specify up to 20 characters. The default is null.

Example: 3rd Prompt=Password2 > >

With this example setting, the terminal server displays these prompts:

    Login:
    Password:
    Password2 > >

Dependencies: This parameter is not applicable when terminal services are disabled or if the Auth parameter is set to a value other than RADIUS or RADIUS/LOGOUT.

Location: `Ethernet > Mod Config > TServ Options`

See Also: TS Enabled, Auth

## 3rd Prompt Seq

Description: Specifies whether the 3rd Prompt appears before or after the login and password prompts.

Usage: Specify one of the following values:

- Last (the default)

  If terminal server security is set to Partial or Full and 3rd Prompt Seq=Last, the Ascend unit sends the user's input to the additional prompt to RADIUS as a part of the authentication request. The user's input for this prompt is not echoed, since it is treated like an extra password.

- First

  If terminal server security is set to Partial or Full and 3rd Prompt Seq=First, the string specified in the Third Prompt parameter appears when the user connects and the user's input is echoed. After the user enters a Login name and Password, the input in response to the third prompt is passed to RADIUS as part of the authentication request.

Example: 3rd Prompt Seq=Last

Dependencies: This parameter is not applicable when terminal services are disabled or if the Auth parameter is set to a value other than RADIUS or RADIUS/LOGOUT.

Location: `Ethernet > Mod Config > TServ Options`

See Also: TS Enabled, Auth

## 7-Even

Description: Specifies whether the MAX uses 7-bit even parity on data it sends toward a dial- in terminal server user.

In 7-bit communication, each device sends only the first 128 characters in the ASCII character set, because each of these characters can be represented by seven bits or fewer. Parity is a way for a device to determine whether it has received data exactly as the sending device transmitted it. Each device must determine whether it will use even parity, odd parity, or no parity.

The sending device adds the 1s in each string it sends and determines whether the sum is even or odd. Then, it adds an extra bit, called a parity bit, to the string. If even parity is in use, the parity bit makes the sum of the bits even; if odd parity is in use, the parity bit makes the sum of the bits odd. For example, if a device sends the binary number 1010101 under even parity, it adds a 0 (zero) to the end of the byte, because the sum of the 1s is already even. However, if it sends the same number under odd parity, it adds a 1 to the end of the byte in order to make the sum of the 1s an odd number.

The receiving device checks whether the sum of the 1s in a character is even or odd. If the device is using even parity, the sum of the 1s in a character should be even; if the device is using odd parity, the sums of the 1s in a character should be odd. If the sum of the 1s does not equal the parity setting, the receiving device knows that an error has occurred during the transmission of the data.

For special ASCII characters (128-256), eight bits are necessary to represent the data. In 8-bit communication, no parity bit is used.

Usage: Specify Yes or No. No is the default and should be used for most applications.

- Yes turns on the use of 7-bit even parity on data sent to dial-in terminal server users.

- No turns off 7-bit even parity.

Example: 7-Even=No

Dependencies: This parameter is not applicable if terminal services are disabled.

## A

## Acct

Description: Specifies the type of accounting service to use for incoming and outgoing bridging/routing calls, and for incoming terminal server calls. When you enable accounting using RADIUS or TACACS+, you must specify the address of the server using the Acct Host parameter.

Usage: Specify one of the following values:

- None (the default) specifies that no accounting takes place.

- RADIUS enables RADIUS accounting.

- TACACS+ enables TACACS+ accounting.

Example: Acct=RADIUS

Dependencies: RADIUS accounting is disabled if you set Auth=RADIUS/LOGOUT.

Location: `Ethernet > Mod Config > Accounting`

See Also: Acct Host #N, Auth

## Acct Checkpoint

Description: Specifies the interval, in minutes, that RADIUS Accounting checkpoint records should be sent for all users. The Checkpoint message contains the same attributes as the Stop message, except that the value for Acct-Status-Type is 3 (Checkpoint).

Usage: Press Enter to open the text field. Type a number from 0 to 60. The default setting is 0, which disables this feature.

Dependencies: The Acct Checkpoint parameter does not apply (Acct Checkpoint=N/A) if the RADIUS Accounting is not used.

Location: `Ethernet > Mod Config > Accounting`

## Acct Host

Description: Specifies the IP address of a connection-specific accounting server to use for information related to this link.

Usage: Specify the IP address of an accounting server.

Example: Acct Host=10.2.3.4/24

Dependencies: This parameter does not apply unless the Acct Type parameter specifies that a connection-specific server will be used.

Location: `Ethernet > Connections > Accounting`

See Also: Acct Type

## Acct Host #N (N=1-3)

Description: Each of these parameters specifies the IP address of an external accounting server. The MAX first tries to connect to server #1. If it receives no response, it tries to connect to server #2. If it receives no response, it tries server #3. If the MAX connects to a server other than the server #1, it continues to use that server until it fails to service requests, even if the first server has come online again.

Note: The addresses must all point to servers of the same type, as specified in the Acct parameter (either TACACS+ or RADIUS).

Usage: Specify an IP address in dotted-decimal format, separating the optional netmask with a slash character. The default value is 0.0.0.0; this setting indicates that no authentication server exists.

Dependencies: The Acct Host #N parameter does not apply when Acct=None.

Location: `Ethernet > Mod Config > Accounting`

See Also: Acct

## Acct-ID Base

Description: Specifies whether the numeric base of the RADIUS Acct-Session-ID attribute is 10 or 16. It controls how the Acct-Session-ID attribute is presented to the accounting server; for example, a base-10 session ID is presented as 1234567890, and a base-16 ID as 499602D2. You can set this parameter globally and for each connection.

The Acct-Session-ID attribute is defined in section 5.5 of the RADIUS accounting specification. See the MAX RADIUS Configuration Guide for more information.

Note: Changing the value of this parameter while accounting sessions are active results in inconsistent reporting between the Start and Stop records.

Usage: Specify one of the following values:

- 10 (decimal) specifies that the numeric base is 10. This is the default.

- 16 (hexadecimal) specifies that the numeric base is 16.

Example: Acct-ID Base=10

Dependencies: This parameter is applies only to RADIUS accounting. (It does not apply to TACACS+.) Also, this parameter applies in a Connection profile only if the Acct Type parameter specifies that connection-specific accounting information will be used.

Location: `Ethernet > Mod Config > Accounting, Ethernet > Connections > Accounting`

See Also: Acct, Acct Type

## Acct Key

Description: Specifies a RADIUS or TACACS+ shared secret. A shared secret acts like a password between the MAX and the accounting server.

Usage: Specify the text of the shared secret. The value you specify must match the value assigned in the RADIUS clients file or the TACACS+ configuration file.

Example: Acct Key=Ascend

Dependencies: This parameter applies in a Connection profile only if the Acct Type parameter specifies that connection-specific accounting information will be used.

Location: `Ethernet > Mod Config > Accounting, Ethernet > Connections > Accounting`

See Also: Acct, Acct Host #N, Acct Type

## Acct Max Retry

Description: The Acct Max Retry parameter addresses the situation where the RADIUS accounting server is not responding to the MAX unit's Accounting Request packets. This parameter sets the number of times the MAX sends an Accounting Request before it gives up. If the RADIUS accounting backoff queue overflows, the MAX discards Accounting Requests whether or not they have reached the maximum number of retries.

Usage: Enter an integer to specify the maximum number of retries allowed. Enter 0 to disable this feature and remove the retry limit.

Dependencies: This parameter applies only when the Acct parameter = RADIUS and the other required RADIUS accounting parameters have been configured.

Location: `Ethernet > Mod Config > Accounting`

See Also: Acct Checkpoint, Acct Timeout, Acct, Acct Host, Acct Port, Acct Src Port, Acct Key, Sess Timer, Acct Reset Terminal, Allow Stop Only

## Acct Port

Description: Specifies the UDP port number that the Ascend unit uses in accounting requests.

Usage: Specify e a UDP port number that matches the port number the accounting daemon uses. For RADIUS, the default value is 1646. For TACACS+, the default value is 49.

Example: Acct Port=1545

Dependencies: This parameter applies in a Connection profile only if the Acct Type parameter specifies that connection-specific accounting information will be used.

Location: `Ethernet > Mod Config > Accounting, Ethernet > Connections > Accounting`

See Also: Acct, Acct Host #N, Acct Type

## Acct Reset Timeout

Description: This parameter forces the MAX to try to return to the primary RADIUS accounting server; specifically, the server defined by the parameter Acct Host #1.

If a timeout occurs while the MAX was waiting for a reply to an accounting request to the primary RADIUS server; the MAX sends the accounting request to secondary RADIUS server defined by Acct Host #2 and if that fails, Acct Host #3. If either of the secondary servers acknowledges the request, the MAX continues to use that server instead of the primary. The Acct Reset Timeout parameter sets the period of time the MAX uses the secondary RADIUS server. At the end of this period of time, the next accounting request the MAX sends to Acct Host #1.

Usage: Enter the period in seconds. Any value from 0 to 86400 is allowed. To disable this feature enter 0 which is equivalent to an infinite number of seconds; that is, the MAX does not return to the primary server as long as the secondary server is replying to requests.

Location: `Ethernet Profile: Ethernet > Mod Config > Acct`

See Also: Acct Host #N

## Acct Src Port

Description: Specifies the source port used to send a RADIUS or TACACS+ accounting request. You can specify the same source port for authentication and accounting requests.

Usage: Specify a port number between 0 and 65535. The default value is 0 (zero); if you accept this value, the MAX can use any port number between 1024 and 2000.

Location: `Ethernet > Mod Config > Accounting`

See Also: Auth Src Port

## Acct Timeout

Description: Sets the amount of time the MAX waits for a response to a RADIUS accounting request. You can set this parameter globally and for each connection.

If it does not receive a response within that time, the MAX sends the accounting request to the next server's address (for example, server #2). If all RADIUS accounting servers are busy, the MAX stores the accounting request and tries again at a later time. It can queue up to 154 requests.

Usage: Specify a number from 1 to 10. The default global value is 0. The default in a Connection profile is 1.

Example: Acct Timeout=3

Dependencies: This parameter applies only to RADIUS accounting. Because TACACS+ uses TCP, it has its own timeout method. Also, this parameter applies in a Connection profile only if the Acct Type parameter specifies that connection-specific accounting information will be used.

Location: `Ethernet > Mod Config > Accounting, Ethernet > Connections > Accounting`

See Also: Acct, Acct Type

## Acct Type

Description: Specifies whether to use a connection-specific accounting server for accounting related to this link.

Usage: Specify one of the following values:

- None (the default)

  The MAX logs information to the accounting server specified in the Ethernet profile.

- User

  The MAX logs information to the accounting server specified in this Connection profile.

- User+Default

  The MAX logs accounting information to both servers.

Example: Acct Type=User

Dependencies: Connection-specific accounting options rely on the setup in the Accounting subprofile of the Ethernet profile.

Location: `Ethernet > Connections > Accounting`

## ACK Suppression

Description: For DTE-initiated calls, this specifies whether the PAD sends an acknowledgment when it receives an opening frame from the DTE and also when it establishes a virtual call with the host.

Usage: Specify one of the following values:

- Off (the default)

  Specifies that the PAD acknowledges the DTE's opening frame and the establishment of a call with the host.

- On

  Specifies that the PAD does not acknowledge either the DTE's opening frame or the establishment of a call with the host.

Dependencies: Keep the following information in mind.

- ACK Suppression only applies to DTE-initiated calls using Transparent or Blind mode.

Location: `Ethernet > Connections > any Connection profile > Encaps options
Etherne > Answer > T3POS options

`

## Activ

Description: Activates a call management time period for an AIM call. You can divide an AIM call that specifies Dynamic call management into time periods, each characterized by separate Activ, Beg Time, Max Ch Cnt, Min Ch Cnt, and Target Util parameters.

Usage: Specify one of the following values:

- Enabled to activate the time period. This is the default for Time Period 1.

- Disabled to ignore the time period. This is the default for Time Periods 2, 3, and 4.

- Shutdown to clear the dynamic call during the time period and redial it at the end of the time period. The MAX can use a shutdown port for answering and dialing calls, but the MAX clears these calls when the shutdown period ends.

Example: Activ=Enabled

Dependencies: This parameter is not applicable unless Call Mgm is set to Dynamic.

Location: `Host/Dual (Host/6) > PortN Menu > Directory > Time Period N`

See Also: Beg Time, Call Mgm, Target Util, Time Period submenu

## Activation

Description: Selects the signals at the serial WAN port that indicate that the DCE (Data Circuit-Terminating Equipment) is ready to connect. Flow control is always handled by the CTS (Clear To Send) signal.

Usage: Specify one of the following values:

- Static specifies that the MAX does not use flow control signals because the DCE is always connected.

- DSR Active specifies that the DCE raises the DSR signal when it is ready.

- DSR+DCD specifies that the DCE raises the DSR and DCD signals when it is ready.

Example: Activation=Static

Location: `Serial WAN > Mod Config`

## Active

Description: Activates a profile (making it available for use) or a route (adding it to the routing table). A dash appears before each deactivated profile or route.

Usage: Specify Yes or No. No is the default.

- Yes activates the profile or feature, making it available for use.

- No disables the profile or feature, making it unavailable for use.

Example: Active=Yes

Location: `Ethernet > Connections, Ethernet > Frame Relay, Ethernet > Names / Passwords, Ethernet > Static Rtes, Ethernet > X.25`

## Add Number

Description: Specifies a series of digits to add to the beginning of the dialout phone number after removing the digits specified by Delete Digits. The device connected to line #2 (typically a PBX) dials this phone number.

Usage: Specify the digits you want the MAX to add to the beginning of the phone number. You can specify any digit string that the PRI switch requires. The default is null.

Example: Add Number=923

Dependencies: This parameter applies only to T1 lines using PBX-T1 conversion.

Location: `Net/T1 > Line Config > Line N`

See Also: Dial #, Delete Digits, Sig Mode

## Add Pers

Description: Specifies the number of seconds that average line utilization (ALU) must persist beyond the target utilization threshold before the MAX adds bandwidth from available channels. When adding bandwidth, the MAX adds the number of channels specified in the Inc Ch Count parameter.

Usage: Specify a number between 1 and 300. The factory default value is 5 for MP+ calls and 20 for AIM calls with dynamic call management.

Example: Add Pers=10

Dependencies: This parameter is not applicable in a Call profile unless Call Mgm=Dynamic. It is not applicable in a Connection profile unless Encaps=MPP.

Location: `Ethernet > Answer > PPP Options, Host/Dual (Host/6) > PortN Menu > Directory, Ethernet > Connections > Encaps Options`

See Also: Call Mgm, Encaps

## Adv Dialout Routes

Description: Specifies whether the MAX should stop advertising (poison) its IP dialout routes if no trunks are available.

Note: This parameter is intended for use when two or more Ascend units on the same network are configured with redundant profiles and routes. It solves a problem that occurred when two or more Ascend units on the same network were configured with redundant profiles and routes. If one of the redundant MAX units lost its trunks temporarily, it continued to receive outbound packets that should have been forwarded to the redundant MAX.

Usage: Specify one of the following values:

- Always (the default) to always advertise IP routes. Use this setting unless you have redundant MAX units or do not use dialout routes.

- Trunks Up to stop advertising ("poison") its IP dialout routes if it temporarily loses the ability to dial out.

Example: Adv Dialout Routes=Always

Dependencies: This parameter is not applicable unless the MAX is being used in a redundant configuration.

Location: `Ethernet > Mod Config`

## Alarm

Description: Specifies whether the MAX traps alarm events and sends a traps-PDU (Protocol Data Units) to the SNMP manager. The following alarm events defined in the Ascend Enterprise MIB. (See the Ascend Enterprise MIB for the most up-to-date information.)

- coldStart (RFC-1215 trap-type 0)

  A coldStart trap signifies that the MAX sending the trap is reinitializing itself so that the configuration of the SNMP manager or the unit might be altered.

- warmStart (RFC-1215 trap-type 1)

  A warmStart trap signifies that the MAX sending the trap is reinitializing itself so that neither the configuration of SNMP manager or the unit is altered.

- linkDown (RFC-1215 trap-type 2)

  A linkDown trap signifies that the MAX sending the trap recognizes a failure in one of the communication links represented in the SNMP manager's configuration.

- linkUp (RFC-1215 trap-type 3)

  A linkUp trap signifies that the MAX sending the trap recognizes that one of the communication links represented in the SNMP manager's configuration has come up.

- frDLCIStatusChange (RFC-1315 trap-type 1)

  A DLCIStatusChange trap signifies that the MAX sending the trap recognizes that one of the virtual circuits (to which a DLCI number has been assigned) has changed state; that is, the link has either been created, invalidated, or it has toggled between the active and inactive states.

- eventTableOverwrite (ascend trap-type 16)

  A new event has overwritten an unread event. This trap is sent only for systems that support Ascend's accounting MIB. Once sent, additional overwrites will not cause another trap to be sent until at least one table's worth of new events have occurred.

Usage: Specify Yes or No. Yes is the default.

- Yes causes the MAX to generate alarm-event traps and send the trap-PDF to the SNMP host.

- No means alarm-events traps are not generated.

Example: Alarm=Yes

Location: `Ethernet > SNMP Traps`

## Alarm Threshold

Description: Specifies a number to use as a threshold for generating an SNMP alarm trap as part of the heartbeat monitoring feature. If the number of monitored packets falls below this number, the following SNMP alarm trap is sent:

    Trap type: TRAP_ENTERPRISE
    Code: TRAP_MULTICAST_TREE_BROKEN (19)
    Arguments:
    1) Multicast group address being monitored (4 bytes),
    2) Source address of last heartbeat packet received (4 bytes)
    3) Slot time interval configured in seconds (4 bytes),
    4) Number of slots configured (4 bytes).
    5) Total number of heartbeat packets received before the MAX started sending SNMP Alarms (4bytes).

When it is running as a multicast forwarder, the MAX is continually receiving multicast traffic. The heartbeat-monitoring feature enables the administrator to monitor possible connectivity problems by continuously polling for this traffic and generating an SNMP alarm trap if there is a traffic breakdown.

Note: Heartbeat monitoring is optional. It is not required for multicast forwarding.

Usage: Specify a number.

Example: Alarm Threshold=3

Dependencies: To set up heartbeat monitoring, you must configure several parameters that define what packets will be monitored, how often and for how long to poll for multicast packets, and the threshold for generating an alarm. These parameters do not apply if multicast forwarding is not in use.

Location: `Ethernet > Mod Config > Multicast`

See Also: HeartBeat Addr, HeartBeat Udp Port, Source Addr, Source Mask, HeartBeat Slot Time, HeartBeat Slot Count

## All Port Diag

Description: Enables or disables a permission that allows an operator to perform all port diagnostic commands listed in the Port Diag menu.

Usage: Specify Yes or No. Yes is the default.

- Yes means the operator can perform all diagnostic commands in the Port Diag menu.

- No means the operator cannot use those commands.

Dependencies: This parameter is not applicable if the Operations permission is disabled.

Example: All Port Diag=No

Location: `System > Security`

See Also: Own Port Diag

## Allow as Client DNS

Description: Specifies whether the local DNS servers should be made accessible to PPP connections if the client DNS servers are unavailable.

Client DNS configurations define DNS server addresses that will be presented to WAN connections during IPCP negotiation. They provide a way to protect your local DNS information from WAN users. Client DNS has two levels: a global configuration that applies to all PPP connections, and a connection-specific configuration that applies to that connection only. The global client addresses are used only if none are specified in the Connection profile.

This parameter acts as a flag to enable the MAX to present the local DNS servers to the WAN connection when all client DNS servers are not defined or available.

Usage: Specify Yes or No. No is the default.

- Yes allows clients to use the local DNS servers.

- No prevent clients from using the local DNS servers.

Example: Allow as Client DNS=No

Location: `Ethernet > Mod Config > DNS`

See Also: Client Assign DNS, Client Pri DNS, Client Sec DNS

## Allow Stop Only

Description: Specifies whether the MAX can send accounting Stop packets that do not contain a username to the RADIUS server. Typically, when RADIUS is turned on, the MAX sends both a Start and a Stop packet to the RADIUS accounting server to record a connection. User authentication is required before a Start packet is sent, so when the connection is terminated before authentication occurs, or when the name and password supplied by the user is rejected, the Start packet is not sent and the Stop packet contains no username.

Usage: Specify one of the following values:

- Yes means that the MAX can send Stop Accounting Packets to RADIUS that do not contain a username.

- No means that you are not restricting the type of Account Request Packet the MAX can send. This is the default.

Dependencies: Allow Stop Only applies only when the Acct parameter is set to RADIUS and the other required RADIUS accounting parameters have been configured.

Location: `Ethernet > Mod Config > Accounting`

Example: Acct Checkpoint, Acct Timeout, Acct, Acct Host, Acct Port, Acct Src Port, Acct Key, Sess Timer, Acct Reset Terminal, Allow Stop Only

## Analog Encoding

Description: Specifies the encoding standard for digitized analog data. Its value is used for all codecs on the MAX.

If an encoding standard other than the default is selected, modem dialout does not work; choosing a non-default encoding method works only for incoming analog data. To arrive at the proper default, you must clear NVRAM. If a System profile already exists on the MAX and NVRAM is not cleared, the value of Analog Encoding always defaults to u-Law, even if you are using E1.

Usage: Specify one of the following values:

- u-Law (MU-Law encoding). This is the default for T1.

- a-Law (A-Law encoding). This is the default for E1.

Example: Analog Encoding=u-Law

Location: `System > Sys Config`

## Ans #

Description: Specifies a phone number to be used for routing calls received on the first T1 line to the second line. This may be an add-on number.

Usage: Specify a phone number. The default is null. You can enter up to 18 characters, and you must limit your specification to these characters: 1234567890()[]!z-*#|

Example: Ans #=555

Dependencies: This parameter applies only to T1 lines using PBX-T1 conversion.

Location: `Net/T1 > Line Config > Line N`

See Also: Sig Mode

## Ans N# (N=1-4)

Description: Specifies a phone number to be used for call-routing purposes. It appears in a number of profiles. In each case, it indicates "route calls received on this number to me." For example, answer numbers specified in the Ethernet profile indicate that calls received on that number should be routed to the bridge/router. In a Modem profile, the answer number indicates that calls received on that number should be routed to an available digital modem.

Note: Only two Answer numbers appear in the Host/BRI line profile.

Usage: Specify the phone number for each Ans N# parameter. You can enter up to 24 characters, which may include a subaddress. You must limit your specification to these characters: 1234567890()[]!z-*#|

Example: Ans 1 #=1212

Dependencies: Call routing using the Answer number works only when the network conveys the number dialed to the answering device. This service is commonly called DNIS (Dialed Number Information Service). Under most circumstances, the Answer number specifies the number of the device being called (the MAX); however, if the switch type is GloBanD, it specifies the number of the calling device. Routing calls by Answer number with EAZ service in Europe requires that you include the EAZ subaddress in the parameter.

Location: `Ethernet > Mod Config > WAN Options, V.34 Modem > Mod Config, Host/BRI > Line Config > Line N, BRI/LT > Line Config > Line N, Host/Dual (Host/6) > PortN Menu > Port Config, V.110 > Mod Config`

See Also: Switch Type, Sub-Adr

## AnsOrig

Description: Specifies whether the MAX will enable incoming calls, outgoing calls, or both, for this connection.

Usage: Specify one of the following values:

- Both specifies that the MAX can initiate calls to the destination specified in the Connection profile, and that the MAX can receive calls from that destination as well.

  Both is the default.

- Call Only specifies that the MAX can dial out to the destination specified in the Connection profile, but cannot answer calls from that destination.

- Ans Only specifies that the MAX can receive calls from the destination specified in the Connection profile, but cannot initiate calls to that destination.

Example: AnsOrig=Both

Dependencies: This parameter is not applicable for leased connections.

Location: `Ethernet > Connections > Telco Options`

See Also: LAN Adrs, Station

## Ans Service

Description: Causes the MAX to route an incoming call from line #1 to line #2 (the PBX) if the data service of the call matches the data service specified by Ans Service. It provides an alternative way to indicate which calls received on line 1 should be forwarded to line 2. If you set both Ans # and Ans Service to null, the MAX does not route incoming calls to line #2.

Usage: Specify one of the following values:

- 56K (56K data calls)

- 56KR (56K calls whose data meets the density restrictions of D4-framed lines)

- 64K (64K data calls)

- Voice (voice calls)

- 384K/H0 (Switched-384K data calls)

- 384KR (Switched-384K calls whose data is restricted and connects to MultiRate or GloBanD data services)

- 1536K (Switched-1536 calls, which are supported only with ISDN NFAS signaling)

- 1536KR (Switched-1536 calls, which are supported only with ISDN NFAS signaling, whose data is restricted)

- 128K, 192K, 256K Other multiples of 64K

  These values are available on a line with MultiRate or GloBanD data services. If the MAX has the MultiRate option, these data services appear.

Example: Ans Service=Voice

Dependencies: This parameter applies only to T1 lines using PBX-T1 conversion.

Location: `Net/T1 > Line Config > Line N`

See Also: Ans #, PBX Type, Sig Mode

## Answer

Description: Specifies how the control-line state determines the way that the MAX answers a call at the port associated with the Port profile.

Note: The Answer parameter setting does not prevent you from answering manually.

Usage: Specify one of the following values:

- Auto (answer every call automatically, regardless of the control-line state). This is the default.

- Terminal (answer manually by using DO 3).

- DTR Active (answer only if DTR is asserted at the port, indicating that the codec is ready to receive data). This setting operates with most codecs configured to answer manually.

- DTR+Ring (answer after one ring if DTR is asserted at the port, for codecs configured to answer manually).

- P-Tel Man (same as DTR+Ring, but used for a Picture Tel codec configured to answer calls manually). The P-Tel Man setting causes the MAX to wait until all channels of the call are synchronized before it asserts RI (Ring Indicate) to inform the codec of the incoming call. When the codec asserts DTR, it tells the MAX that it is ready.

- V.25bis (answer according to V.25 bis hardware handshaking). The port must support AIM functionality for this value to have any effect. Note that the MAX does not process the data that go to its AIM ports; the codec processes the data.

- V.25bis-C (same as V.25bis, but the CTS signal cannot change state during a call).

- X.21 (answer according to X.21 hardware handshaking, as described in CCITT Blue Book Rec. X.21). The X.21 dialing interface on the MAX is often used for direct dialing and answering from an attached codec, router, or other codec.

- None (use the port for outgoing calls only).

Example: Answer=Auto

Dependencies: The Answer parameter does not prevent you from answering manually.

## APP Host

Description: Specifies the IP address of the host that runs the APP Server Utility. Enigma Logic SafeWord AS and Security Dynamics ACE authentication servers are examples of APP servers.

Usage: Specify the IP address of the authentication server.

The address consists of four numbers between 0 and 255, separated by periods. Separate the optional netmask from the address using a slash. The default value is 0.0.0.0/0. The default setting specifies that no APP server is available.

Example: APP Host=200.65.207.63/29

Dependencies: This parameter applies only to outgoing calls using security card authentication. You must set Send Auth=PAP-Token and APP Server=Yes for the APP Host parameter to have any effect.The APP Server utility must be running on a UNIX or Windows workstation on the local network.

Location: `Ethernet > Mod Config > Auth`

See Also: APP Server, Send Auth

## APP Port

Description: Specifies the UDP port number monitored by the APP server identified in the APP Host parameter.

Usage: Specify a UDP port number. Valid port numbers range from 0 to 65535. The default value is 0, which indicates that no UDP port is being monitored by the APP server.

Example: APP Port=35

Dependencies: This parameter applies only to outgoing calls using security card authentication. You must set Send Auth=PAP-Token and APP Server=Yes for the APP Port parameter to have any effect.The APP Server utility must be running on a UNIX or Windows workstation on the local network.

Location: `Ethernet > Mod Config > Auth`

See Also: APP Server, Send Auth

## APP Server

Description: Enables responses to security card password challenges by using the APP Server utility on a UNIX or Windows workstation.

Usage: Specify Yes or No. No is the default.

- Yes enables the MAX to respond to password challenges via the APP Server utility running on a local host.

- No disables the use of the APP Server utility

Example: APP Server=Yes

Dependencies: This parameter applies only to outgoing calls using security card authentication. You must set Send Auth=PAP-Token and APP Server=Yes for the APP Port parameter to have any effect.The APP Server utility must be running on a UNIX or Windows workstation on the local network.

Location: `Ethernet > Mod Config > Auth`

## AppleTalk

Description: Specifies whether the MAX enables an AppleTalk stack to support AppleTalk routing and ARA (AppleTalk Remote Access) connections.

Usage: Specify Yes or No. No is the default.

- Yes enables AppleTalk to support AppleTalk routing and ARA connections.

- No disables AppleTalk.

Example: AppleTalk=Yes

Location: `Ethernet > Mod Config`

See Also: ARA, Encaps, Route AppleTalk, AppleTalk Router

## AppleTalk Router

Description: Determines whether the MAX is a seed or non-seed router. A routed AppleTalk network must include at least one seed router. Other routers on the network can have a network range of 0, which means that they acquire the network-number range from RTMP packets sent by the seed router. If you specify Non-Seed, the router learns network number and zone information from other routers. You can set up more than one router on a network to be a seed router, but all seed routers must have the same value for both the start and end of the network number range.

Usage: Specify one of the following:

- Seed

  Specifies that the router is an AppleTalk seed router. If you select AppleTalk Router=Seed, enter the network-number range in its port description. To prevent conflicts, all seed routers on the same network must have the same value for the start and end of the network-number range.

  The value zero (0) does not cause a conflict. Non-seed routers and other seed routers can have a value of 0 for the network number range. A router with a value of 0 for a network number range does not send this value to other routers, which means it does not seed the other routers in network with this range. A router with the zero value will not acquire a value for that network number range.

  You must also specify the Default Zone name for the seed router, and the names of any zones that the seed router can seed.

- Non-Seed

- Specifies that the router is not an AppleTalk seed router. It will acquire a network number range value from a seed router on the network.

- Off (the default)

Location: `Ethernet > Mod Config > AppleTalk Options

` See Also: Route AppleTalk, AppleTalk, Net Start, Net End, Peer (Appletalk Options), Default Zone, Zone Name #n.

## ARA

Description: Specifies whether the MAX allows incoming ARA (AppleTalk Remote Access) calls.

Usage: Specify Yes or No. Yes is the default.

- Yes allows the MAX to answer incoming ARA calls, provided they meet all other connection criteria.

- No means the MAX will not answer incoming ARA calls.

Example: ARA=Yes

Dependencies: This parameter is not applicable if AppleTalk is not enabled.

Location: `Ethernet > Answer > Encaps`

See Also: AppleTalk, Encaps

## Area

Description: Specifies the OSPF area that this interface belongs to.

Usage: Specify an area ID in dotted-decimal format. The default 0.0.0.0 represents the backbone network.

Example: Area=0.0.0.1

Dependencies: At this release, we recommend that you configure the local and WAN interfaces in the same area.

Location: `Ethernet > Connections > OSPF Options, Ethernet > Mod Config > OSPF Options`

## AreaType

Description: Specifies the type of OSPF area this interface belongs to. If a network is large, the size of the database, time required for route computation, and related network traffic become excessive. An administrator can partition an AS into areas to provide hierarchical routing connected by a backbone.

The backbone area is special and always has the area number 0.0.0.0. Other areas are assigned area numbers that are unique within the autonomous system.

Note: You must set the area-type parameter consistently on all OSPF routers within the area.

Usage: Specify one of the following values:

- Normal (the default).

  In a normal OSPF area, the router maintains information about external routes.

- Stub

  For areas that are connected only to the backbone by one ABR (that is, the area has one exit point), there is no need to maintain information about external routes. To reduce the cost of routing, OSPF supports stub areas, in which all external routes are summarized by a default route. Stub areas are similar to regular areas except that the routers do not enter external routes in the area's databases.

Example: AreaType=Normal

Dependencies: You must set the AreaType parameter consistently on all OSPF routers within the area.

Location: `Ethernet > Connections > OSPF Options, Ethernet > Mod Config > OSPF Options`

## Ascend-Shared-Profile-Enable

Description: Enables or disables sharing of a RADIUS user file for multiple incoming users.

Note: To apply Shared Profiles on a per RADIUS user profile basis, you have to disable profile sharing on a system-wide basis by setting Ethernet > Mod Config > Shared Prof = No on the MAX

Usage: You can specify one of the following settings:

- Ascend-Shared-Profile-Enable = Shared-Profile-Yes specifies that multiple incoming calls can share this RADIUS user profile.

- Ascend-Shared-Profile-Enable = Shared-Profile-No specifies that multiple incoming calls cannot share a local Connection Profile.

  The default value is Shared-Profile-No

Dependencies: For the Ascend-Shared-Profile-Enable attribute to apply, you must disable shared profiles for the MAX as a whole with Ethernet > Mod Config > Shared Prof = No.

## ASE-tag

Description: Specifies the OSPF ASE tag of this link. The tag is a 32-bit hexadecimal number attached to each external route. This field is not used by the OSPF protocol itself. It may be used by border routers to filter this record.

Usage: Specify a 32-bit hexadecimal number. The factory default is c0:00:00:00.

Example: ASE-tag=c8:ff:00:00

Location: `Ethernet > Connections > OSPF Options, Ethernet > Mod Config > OSPF Options, Ethernet > Static Rtes`

## Assign Adrs

Description: Enables or disables dynamic IP address assignment for incoming calls.

Usage: Specify Yes or No. No is the default.

- Yes enables the MAX to assign an IP address to an incoming PPP call that requests dynamic assignment, provided it has access to a pool of designated IP address.

- No disables dynamic IP address assignment.

Example: Assign Adrs=Yes

Dependencies: The MAX must have at least one configured pool of IP addresses, either locally or on a RADIUS server.

Location: `Ethernet > Answer`

See Also: Encaps, LAN Adrs, Pool # Count, Pool # Start, Recv Auth, WAN Alias

## ATMP Gateway

Description: Instructs the MAX to send data it receives back from the home network on this connection to the mobile node.

Usage: Specify Yes or No. No is the default.

- Yes enables the MAX to send data it receives back from the home network on this connection to the mobile node.

- No disables this function.

Example: ATMP Gateway=Yes

Dependencies: This parameter is not applicable unless the MAX is configured as an ATMP home agent in gateway mode.

Location: `Ethernet > Connections > Session Options`

See Also: ATMP Mode, Password, Type, UDP Port

## ATMP Mode

Description: Specifies whether ATMP (Ascend Tunnel Management Protocol) is enabled and, if so, whether this unit is a home agent, a foreign agent, or both.

Usage: Specify one of the following values:

- Disabled (the default) specifies that ATMP is not enabled.

- Home specifies that this unit is a home agent.

- Foreign specifies that this unit is a foreign agent.

- Both specifies that the MAX will function as both a home agent and foreign agent on a tunnel-by-tunnel basis.

Example: ATMP Mode=Home

Dependencies: If you set ATMP Mode=Disabled, all other fields in the ATMP Options menu are not applicable.

Location: `Ethernet > Mod Config > ATMP Options`

See Also: ATMP Gateway, Password, Type, UDP Port

## Attributes

Description: Specifies which RADIUS attributes will be required to identify a session when Session Key is enabled.

Usage: Specify one of the following values:

- Any (the default)

  Any Attribute can be used to identify the session. If multiple attributes are sent, the order in which they are checked is (1) session key, (2) session id, (3) user name, (4) IP address.

- Session

  Only the session key attribute is checked for identification.

- All

  All Attributes that are applicable must be present and pass validation before any operation is performed on the connection. For example, if a session has a user name, IP address, session id and session key, than all four attributes must be sent. As another example, if a session has a user name, session id and session key, than these attributes must be sent; the IP address is not required.

Example: Attributes=Any

Dependencies: This parameter does not apply if Session Key is disabled.

Location: `Ethernet > Mod Config > RADIUS Server`

See Also: Session Key

## Auth

Description: Specifies the type of external authentication server to access for incoming connections. For details on RADIUS, see the MAX RADIUS Configuration Guide. See the MAX Security Supplement for details on other authentication servers.

Usage: Specify one of the following values:

- None (the default) to disable the use of an authentication server.

- TACACS

  Access a TACACS server. TACACS supports PAP, but not CHAP authentication.

- TACACS+

  Access a TACACS+ server. TACACS+ supports PAP, but not CHAP authentication and provides more extensive accounting statistics and a higher degree of control than TACACS authentication.

- RADIUS

  Access a RADIUS server. In a RADIUS query, the MAX provides a user ID and password to the server. If the validation succeeds, the server sends back a complete profile; this profile specifies routing, packet filtering, destination-specific static routes, and usage restrictions for the user. RADIUS supports PAP and CHAP, and terminal server validation.

- RADIUS/LOGOUT

  This setting is identical to RADIUS, except that when you select radius-logout, the MAX sends a request to the RADIUS server to initiate logout when the session ends.

  Use this setting to set up an AppleTalk Remote Access connection to a SecurID server using RADIUS.

- Defender

  Access a Digital Pathways Defender authentication server.

- SECURID

  Access a SecurID ACE server.

Note: If the MAX is configured to use SecurID ACE authentication, all authenticated users are given service only according to the parameters of the TServ Options submenu for the Ethernet profile. There currently is no way to get user-specific configuration information from the SecurID ACE server, except by using RADIUS.

Example: Auth=RADIUS (for authentication using RADIUS), Auth=RADIUS/LOGOUT (for authentication using RADIUS and a SecurID server).

Dependencies: This parameter requires a server address in an Auth Host # parameter.

Location: `Ethernet > Mod Config > Auth`

See Also: Auth Host, Auth Key, Auth Port, Auth Timeout, Encaps

## Auth Boot Host #1

Description: Specifies the IP address of the first RADIUS bootup server the MAX contacts, at startup, to obtain ZGR subaddresses or answer numbers.

Usage: Specify an IP address in dotted decimal notation. The default value is 0.0.0.0. If you accept the default, the MAX does not use a RADIUS server for ZGR subaddresses or answer numbers.

Dependencies: You can use the ZGR subaddress and answer number feature without specifying a special bootup server. If you do not specify a special bootup server, the MAX uses the authentication server specified by Auth Host in the Ethernet > Mod Config menu to store the ZGR subaddresses and answer numbers.

If you set the Auth Boot Host #1 parameter, you must also specify a value for the Auth Key and Auth Src Port parameters in the Ethernet > Mod Config > Auth menu.

Location: `Ethernet > Mod Config > Auth`

See Also: Auth Boot Host #2, Auth Boot Port

## Auth Boot Host #2

Description: Specifies the IP address of the RADIUS server the MAX contacts if the server specified by Auth Boot Host #1 fails to respond.

Usage: Specify an IP address in dotted decimal notation. The default value is 0.0.0.0. If you accept the default, the MAX does not use a secondary RADIUS server for ZGR subaddresses or answer numbers.

Dependencies: You can use the ZGR subaddress and answer number feature without specifying a special bootup server. If you do not specify a special bootup server, the MAX uses the authentication server specified by Auth Host in the Ethernet > Mod Config menu to store the ZGR subaddresses and answer numbers.

If you set the Auth Boot Host #2 parameter, you must also specify a value for the Auth Key and Auth Src Port parameters in the Ethernet > Mod Config > Auth menu.

Location: `Ethernet > Mod Config > Auth`

See Also: Auth Boot Host #1, Auth Boot Port

## Auth Boot Port

Description: Specifies the port number to use when contacting the RADIUS server specified by Auth Boot Host #1 or Auth Boot Host #2.

Usage: Specify a value between 0 and 1024. The default value is 0 (zero), which disables the RADIUS bootup-server feature.

Location: `Ethernet > Mod Config > Auth`

Auth Boot Host #1, Auth Boot Host #2

## Auth Host #N (N=1-3)

Description: Each of these parameters specifies the IP address of an external authentication server. The MAX first tries to connect to server #1. If it receives no response, it tries to connect to server #2. If it receives no response, it tries server #3. If the MAX connects to a server other than the server #1, it continues to use that server until it fails to service requests, even if the first server has come online again.

Note: The addresses must all point to servers of the same type, as specified in the Auth parameter (RADIUS, TACACS, or TACACS+). If you are using Defender or SecurID authentication, only Auth Host #1 is applicable, because the MAX can access only one of those servers.

Usage: Specify an IP address in dotted-decimal format, separating the optional netmask with a slash character. The default value is 0.0.0.0; this setting indicates that no authentication server exists.

Example: Auth Host #1=10.207.23.6

Dependencies: This parameter does not apply if authentication services are disabled.

Location: `Ethernet > Mod Config > Auth`

See Also: Auth, Auth Key, Auth Port, Auth Timeout

## Auth Key

Description: Specifies an authentication key, which is typically a shared secret with the authentication server.

- For RADIUS, this is a string up to 22 characters. Because the MAX can act both as a client to external servers and as an on-board server responding to client commands, this parameter is configured in two places for RADIUS.

- If the MAX is acting as a TACACS or TACACS+ client, this is a password supplied by the MAX to the server.

- If the MAX is acting as a Defender client, this is a DES secret key shared between the MAX and the Defender authentication server. This key is also used for authentication by the MAX in its role as a Defender authentication agent.

- If the MAX is acting as a SecurID client, this parameter is not applicable. See SecurID DES Encryption and SecurID Node Secret for details.

Usage: Specify the authentication key.

Example: Auth Key=Ascend

Dependencies: This value of this parameter depends on the setting of the Auth parameter. If Auth is set to SECURID, this parameter is not applicable.

Location: `Ethernet > Mod Config > Auth`

See Also: Auth, Auth Host, Auth Port, Auth Timeout, SecurID DES Encryption, SecurID Node Secret

## Auth Pool

Description: Enables or disables dynamic address assignment for RADIUS-authenticated IP routing connections. The RADIUS server must be configured with at least one pool of addresses for assignment, and must be running the Ascend daemon. See the MAX RADIUS Configuration Guide for details.

Usage: Specify Yes or No. No is the default.

- Yes means dial-in callers can obtain an IP address dynamically from the RADIUS server.

- No disables dynamic IP address assignment for RADIUS-authenticated connections.

Example: Auth Pool=Yes

Location: `Ethernet > Mod Config > Auth`

See Also: Auth

## Auth Port

Description: Specifies the UDP or TCP port to use to communicate with the external authentication server. It must match the port specified for use in the server's configuration.

- If the MAX is acting as a RADIUS client, this is the UDP destination port to use for authentication. The UDP port used by RADIUS daemons is specified in the /etc/services file (UNIX).

- If the MAX is acting as a TACACS or TACACS+ client, it specifies the UDP destination port to use for authentication (49 by default).

- If the MAX is acting as a RADIUS server, this is the UDP port to use for the on-board RADIUS server. (The on-board server is a mechanism that allows the MAX to respond to messages from the radius daemon, as described in the MAX RADIUS Configuration Guide.) It is set to 1700 by default.

- If the MAX is acting as a Defender client, this is the TCP port to use to communicate with the server. It is set to 2626 by default.

- If the MAX is acting as a SecurID client, this is the TCP port to use to communicate with the server. It is set to 5500 by default.

Note: Make sure that the number you specify matches what is actually in use by the authentication server daemon.

Usage: Specify the port number used by the server.

Example: Auth Port=1565

Location: `Ethernet > Mod Config > Auth`

See Also: Auth, Auth Host, Auth Key, Auth Timeout

## Auth Req

Description: Specifies how the MAX acts if an authentication request times out after a call has been CLID-authenticated. If set to Yes, calls that have passed CLID-authentication are dropped if the external authentication request times out. If set to No, CLID-authentication connections are allowed even if there is no response form the external server.

Usage: Specify Yes or No. Yes is the default.

- Yes means the MAX drops a call if the authentication requests times out after the call has been CLID-authenticated.

- No means the MAX attempts external authentication, but if the request times out, it allows the session to be established based solely upon CLID authentication.

Example: Auth Req=Yes

Dependencies: This parameter is not applicable unless CLID authentication is required.

Location: `Ethernet > Mod Config > Auth`

See Also: Auth, Auth Host # Auth Key, Auth Pool, Auth Port, Auth Timeout

## Auth Reset Timeout

Description: This parameter forces the MAX to try to return to the primary RADIUS authentication server; specifically, the server defined by the parameter Auth Host #1.

If a timeout occurs while the MAX was waiting for a reply to an authentication request to the primary RADIUS server; the MAX sends the authentication request to secondary RADIUS server defined by Auth Host #2 and if that fails, Auth Host #3. If either of the secondary servers acknowledges the request, the MAX continues to use that server instead of the primary. Auth Reset Timeout parameter sets the period of time the MAX uses the secondary RADIUS server. At the end of this period of time, the next authentication request the MAX sends to Auth Host #1.

Usage: Enter the period in seconds. Any value from 0 to 86400 is allowed. To disable this feature enter 0 which is equivalent to an infinite number of seconds; that is, the MAX does not return to the primary server as long as the secondary server is replying to requests.

Dependencies: This parameter will be N/A if Auth=None or Auth=TACACS+ in the this profile.

Location: `Ethernet Profile: Ethernet > Mod Config > Auth`

See Also: Auth Host #N

## Auth Send Attr 6,7

Description: Specifies whether the MAX sends values for RADIUS attributes 6 and 7. Typically, it generates appropriate values for RADIUS attribute 6 (user-service) and 7 (framed- protocol) and includes them in authentication requests for incoming calls. To support RADIUS servers that should not receive that information, you can disable this behavior.

Note: When this parameter is set to No, the system cannot differentiate between terminal server users, async PPP users that authenticate via the terminal server, and SLIP users that authenticate via the terminal server.

Usage: Specify Yes or No. Yes is the default.

- Yes causes attributes 6 and 7 to be sent to the RADIUS Server in the authentication request. Use this setting if you want to control access to PPP and SLIP via the terminal server explicitly by the RADIUS response, or if you use a MERIT RADIUS server.

- No excludes attributes 6 and 7 from authentication requests.

Example: Auth Send Attr 6,7=Yes

Dependencies: This parameter applies only to RADIUS authentication.

Location: `Ethernet > Mod Config > Auth`

## Auth Src Port

Description: Specifies the source port used to send a remote authentication requests. You can define a source port for all the external authentication services the MAX supports. You can specify the same source port for authentication and accounting requests.

Usage: Specify a port number between 0 and 65535. The default value is 0 (zero); if you accept this value, the MAX can use any port number between 1024 and 2000.

Example: Auth Src Port=0

Dependencies: This parameter does not apply if external authentication is not in use.

Location: `Ethernet > Mod Config > Auth`

See Also: Acct Src Port

## Auth Timeout

Description: Specifies the number of seconds between retries to the external authentication server.

- If the MAX is acting as a RADIUS, TACACS, or TACACS+ client, the MAX waits the specified number of seconds for a response to an authentication request. If it does not receive a response within that time, it times out and sends the authentication request to the next authentication server (for example, Auth Host #2).

- If the MAX is acting as a Defender or SecurID client (which support only one server address), the MAX waits the specified number of seconds before assuming that the server has become nonfunctional. For more information about SecurID timeouts, see SecurID Host Retries.

Note: Because remote authentication is tried first if the Local Profiles First parameter set to No, the MAX waits for the remote authentication to time out before attempting to authenticate locally. This timeout may take longer than the timeout specified for the connection and could cause all connection attempts to fail. To prevent this, set the authentication timeout value low enough to not cause the line to be dropped, but still high enough to permit the unit to respond if it is able to. The recommended time is 3 seconds.

Usage: Specify a number from 1 to 10. The default is 1.

Example: Auth Timeout=20

Dependencies: This parameter applies only when using an external authentication server.

Location: `Ethernet > Mod Config > Auth`

See Also: Auth, Auth Host, Auth Key, Auth Port, SecurID Host Retires.

## Auth TS Secure

Description: Specifies whether remote dialin users will be dropped if the immediate login service is TCP-Clear or Telnet and a host is not specified in the RADIUS user profile.

Usage: Specify Yes or No. Yes is the default.

- Yes means the connection is dropped if no login host is specified for a terminal-server connection whose immediate service is set to TCP or Telnet.

- No means the caller will have access to the terminal-server interface instead.

Example: Auth TS Secure=Yes

Dependencies: This parameter does not apply if terminal services are disabled or if RADIUS authentication is not in use.

Location: `Ethernet > Mod Config > Auth`

See Also: Auth, TS Enabled

## AuthKey

Description: Specifies an authentication key (a password). for OSPF routing. The value of this parameter is a 64-bit clear password inserted into the OSPF packet header. It is used by OSPF routers to allow or exclude packets from an area. The default value for OSPF is ascend0.

Usage: Specify a string up to 9 characters for an OSPF auth-key.

Example: AuthKey=Ascend

Dependencies: This parameter is not used if AuthType is None.

Location: `Ethernet > Connections > OSPF Options, Ethernet > Mod Config > OSPF Options`

See Also: AuthType

## AuthType

Description: Specifies the type of authentication in use for validating OSPF packet exchanges: Simple (the default) or None. Simple authentication is designed to prevent configuration errors from affecting the OSPF routing database. It is not designed for firewall protection.

Usage: Specify one of the following values:

- None

  Routing exchanges are not authenticated. The 64-bit authentication field in the OSPF header may contain data, but it is not examined on packet reception. When you use this setting, the MAX performs a checksum on the entire contents of each OSPF packet (other than the 64-bit authentication field) to ensure against data corruption.

- Simple

  This setting requires that you specify a 64-bit field in the auth-key parameter. Each packet sent on a particular network must have the configured value in its OSPF header 64-bit authentication field. Simple is the default.

Example: AuthType=Simple

Location: `Ethernet > Connections > OSPF Options, Ethernet > Mod Config > OSPF Options`

See Also: AuthKey

## Auto-BERT

Description: Specifies that an automatic byte-error test (Auto-BERT) begins as soon as a call connects and runs for the number of seconds you specify for Auto-BERT.

During the test, the MAX monitors the entire data stream between codecs. At the end of the time period, if any channels have failed, the MAX clears the bad channels, redials, and repeats the test. The Call Status window displays BERT MAST at the dialing end of the call, and BERT SLAVE at the answering end of the call. These status windows display the results of the Auto-BERT:

- The Line Errors window displays errors recorded on all current channels.

- The Session Errors window for a specific AIM port displays the cumulative error count for all channels connected to the port.

- The Port Info window displays the quality of all active calls.

- The Statistics window displays the quality of a call on a specific AIM port.

The maximum number of errors that can accumulate per channel is approximately 65,000. Note that the MAX reports the total number of errors for each channel during the current call, not the error rate.

The MAX resets the error display for the current call to 0 (zero) when the call disconnects, or if the MAX disconnects a channel during the Auto-BERT or during the call itself. You can abort the Auto-BERT at any time by choosing the command DO Beg/End BERT.

Usage: Specify 15, 30, 60, 90, or 120 seconds, or Off. The default setting is Off., which disables the Auto-BERT.

Example: Auto-BERT=Off

Dependencies: You increase call setup time by at least the amount of time you specify for the Auto-BERT parameter.

Location: `Host/Dual (Host/6) > PortN Menu > Directory`

## Auto-Call X.121 Addr

Description: Specifies the X.25 host to call immediately when an X.25/PAD session is established via this Connection profile. If Auto-Call X.121 Addr specifies an address, the PAD session can begin automatically; otherwise, the MAX displays the terminal-server prompt, where the user can issue the "pad" command to begin a session.

Usage: Specify the information needed to call the X.25, up to 48 characters. Use this format:

    <address >  [*P|*D|*F <data > ]]

- <address > is the X.121 address to which the call is made (up to 15 characters).

- *P means do not echo what is entered at the keyboard after the *P command, even if you set X.3 parameter number 2 to Echo. (This is to protect passwords that are carried with the call user data.)

- *D means echo what is entered at the keyboard after the *D command.

- *F means that what follows the *F command is fast-select data.

- <data > is inserted into the last 12 bytes of the user data field.

Example: Auto-Call X.121 Addr=031344159782111 *Dpassword

Dependencies: This parameter applies only to X.25/PAD connections.

Location: `Ethernet > Connections > Encaps Options`

## Auto Logout

Description: Specifies whether the MAX automatically logs a user out when a device disconnects from the MAX unit's control port or when the MAX loses power.

Usage: Specify Yes or No. No is the default.

- Yes causes the MAX to log out the current user and go back to default privileges when a device disconnects from the MAX unit's control port or when the MAX loses power.

- No disables auto-logout.

Example: Auto Logout=Yes

Location: `System > Sys Config`

## Aux Send PW

Description: Specifies the password the MAX sends when it adds channels to a multichannel PPP call that uses PAP-TOKEN-CHAP authentication. The MAX obtains authentication of the first channel of this call from the user's hand-held security card.

Usage: Specify a password. This password must match the one set up for your MAX in the RADIUS users file on the NAS (network authentication server).

Example: Aux Send PW=Ascend

Dependencies: This parameter applies only to multichannel PPP calls.

Location: `Ethernet > Connections > Encaps Options`

See Also: Send Auth

## B

## B&O Restore

Description: Specifies how many seconds the MAX waits before restoring a nailed-up channel to an FT1-B&O call-that is, a call for which Call Type=FT1-B&O.

When the quality of a nailed-up channel falls to Marginal or Poor in an FT1-B&O call, the MAX drops all the nailed-up channels. It then attempts to replace dropped nailed-up channels with switched channels. It also monitors dropped nailed-up channels; when the quality of all dropped channels changes to Fair or Good, the MAX reinstates them. The B&O Restore parameter specifies how long the MAX waits before reinstating the channels.

Usage: Specify the number of seconds you want the MAX to wait before restoring a nailed-up channel. You can enter a number between 30 and 30000. The default is 300.

Example: B&O Restore=50

## BN Prt/Grp (N=1-2)

Description: BN Prt/Grp has two meanings, depending on a channel's configured usage. For switched channels, it specifies a port number to be used with the B N Slot parameter for call routing purposes. In effect, it reserves the channel for calls to and from that port. For nailed channels, it assigns a group number, which will be referenced from Call or Connection profiles to use the nailed channels for a connection.

Usage: Specify a number.

Dependencies: When specifying a port number for call routing purposes, you must also specify the slot number using B N Slot.

Example: B1 Prt/Grp=5

Location: `Net/BRI > Line Config > Line N, BRI/LT > Line Config > Line N`

See Also: BN Slot, Group

## BN Slot (N=1-2)

Description: Specifies a slot number to be used for call routing purposes. In effect, it reserves the channel for calls to and from that slot. Note that there is no way to tell whether a call will come in on the first or second B channel of a BRI line, so both B1 Slot and B2 Slot should specify the same slot number.

Usage: Specify one of the following values:

- 0 (Zero, the default). Zero means this parameter is not used to route incoming calls.

- 1 and 2 are invalid settings, because they represent the built-in slots containing T1 or E1 lines.

- 3 through 8 represent expansion slots. When looking at the back panel of the MAX unit, slot #3 is the bottom slot in the left bank of slots, followed by #4 and #5 in ascending order. Slot #6 is the bottom right slot, followed by #7 and #8 in ascending order.

- 9 represents the LAN. Calls are routed to the bridge/router module.

Dependencies: This parameter is applicable only for switched channels.

Example: B1 Slot=7

Location: `Net/BRI > Line Config > Line N`

See Also: BN Prt/Grp

## BN Trnk Grp(N=1-2)

Description: Assigns a B channel to a trunk group, making it available for outbound calls. Note that you cannot specify the same trunk group number for channels that belong to a BRI and PRI line.

Usage: Specify a number between 4 and 9 for each trunk group. The default is 9.

Example: B1 Trnk Grp=8

Dependencies: This parameter applies only if trunk groups are enabled in the System profile.

Location: `Net/BRI > Line Config > Line N, BRI/LT > Line Config > Line N`

See Also: B2 Trnk Grp, Ch N Trnk Grp, Dial #

## BN Usage(N=1-2)

Description: Specifies the B channel's usage.

Usage: Specify one of the following values:

- Switched (the default) specifies that the channel supports switched connectivity.

- Nailed specifies that the channel is used for a leased connection.

- Unused specifies that the MAX does not use the channel.

Example: B1 Usage=Switched

Location: `Net/BRI > Line Config > Line N, BRI/LT > Line Config > Line N`

See Also: B2 Usage

## Back-to-back

Description: Enables you to set up DASS-2 and DPNSS lines in a back-to-back connection. A crossover cable connects an E1 port of one MAX to an E1 port of another MAX. No switch is required, and the connection is entirely local. One MAX should be set up for DTE operation, and the other for DCE operation.

Usage: Specify Yes or No. No is the default.

- Yes specifies that the MAX is set up for DTE operation.

- No specifies that the MAX is set up for DCE operation.

Dependencies: This parameter applies only to E1 lines whose signaling mode is DPNSS.

Location: `Net/E1 > Line Config`

See Also: Sig Mode

## Backup

Description: Specifies the number of a backup Connection profile for a nailed connection. It is intended as a backup if the far-end device goes out of service, in which case the backup call is made. It is not intended to provide alternative lines for getting to a single destination.

Note: A Connection profile's number is the unique portion of the number preceding the profile's name in the Connections menu.

Usage: Specify the Connection profile number. The default value is null.

Example: Backup=22

Location: `Ethernet > Connections > Session Options`

See Also: Name

## BACP

Description: Enables or disables the Bandwidth Allocation Control Protocol (BACP). If enabled, connections encapsulated in MP (RFC 1990) use BACP to manage dynamic bandwidth on demand. Both sides of the connection must support BACP.

Note: BACP uses the same criteria as MP+ connections for managing bandwidth dynamically.

Usage: Specify Yes to enable BACP. No is the default.

Example: BACP=Yes

Dependencies: This parameter applies only to connections encapsulated in MP.

Location: `Ethernet > Answer > PPP Options, Ethernet > Connections > Encaps Options`

See Also: Encaps, Dyn Alg, Sec History, Target Util, Add Pers, Sub Pers, Base Ch Count, Min Ch Count, Max Ch Count, Inc Ch Count, Dec Ch Count

## Banner

Description: Specifies the text to be used as the terminal server login banner.

Usage: Specify the banner text. You can enter up to 84 alphanumeric characters. The default is ** Ascend MAX Terminal Server **.

Example: Banner="Welcome to ABC Corporation"

Dependencies: This parameter is not applicable if terminal-services are disabled or if the terminal-server obtains its login setup from RADIUS.

Location: `Ethernet > Mod Config`

See Also: Remote Conf, TS Enabled

## Base Ch Count

Description: Specifies the number of channels to use to set up a session initially. If it is a fixed session using MP, Base Ch Count specifies the total number of channels to be used for the call. For an AIM, BONDING, or multichannel PPP call, the channel count may be augmented.

A BONDING Mode 1 call cannot exceed 12 channels. For an MP+ call, the number is limited by the number of available channels. For a Combinet link, you can specify up to two channels. No matter what type of link you use, the amount you specify cannot exceed the maximum channel count set by the Max Ch Count parameter.

If the data service is MultiRate or GloBanD, and the data service you select is a multiple of 64 kbps, specify a value for Base Ch Count that is a multiple of 6. If the data service is 384K/H0, 384KR, or GloBanD, the value you specify for Base Ch Count should be divisible by 6. In this case, specify a value of 6, 12, 18, 24, or 30.

Usage: Specify a number from 1 to 32. The default is 1.

Example: Base Ch Count=2

Dependencies: This parameter does not apply for leased connections.

Location: `Host/Dual (Host/6) > PortN Menu > Directory, Ethernet > Connections > Encaps Options`

See Also: Call Mgm, Data Svc, Max Ch Count, Parallel Dialing

## Beg Time

Description: Specifies the start-time of a dynamic AIM call's time period. You do not need to specify an ending time; the starting time specified by the Beg Time parameter of the next time period is the implicit ending time.

Usage: Specify the time of day you want the time period to begin. The setting you specify must have the format <hour > :<minutes > :<seconds > . The default is 00:00:00.

Example: Beg Time=13:59:59

Dependencies: This parameter applies only when Call Mgm=Dynamic.

Location: `Host/Dual (Host/6) > PortN Menu > Directory > Time Period N`

See Also: Time Period

## Bill #

Description: Specifies a telephone number to be used for billing purposes. If a number is specified, it is used either as a billing suffix or the calling party number. For robbed-bit lines, the MAX uses the billing-number as a suffix that is appended to each phone number it dials for the call.

For PRI lines, the MAX uses the billing-number parameter rather than the phone number ID to identify itself to the answering party.

If the calling party uses the billing-number parameter instead of its phone number as its ID, the CLID used by the answering side is not the true phone number of the caller. This situation presents a security breach if you use CLID authentication. Further, be aware that if you specify a value for the billing-number parameter, there is no guarantee that the phone company will send it to the answering device.

Note: For outgoing calls on a PRI line, the value of the Bill # parameter in the Dial Plan profile overrides the value of the Bill # parameter in the Call profile and Connection profile.

Usage: Specify the billing number provided by the carrier. You can enter up to 24 characters. The default value is null.

Example: Bill #=666

Location: `Host/Dual (Host/6) > PortN Menu > Directory, Ethernet > Connections > Telco Options, System > Dial Plan, Ethernet > Frame Relay, Ethernet > X.25`

See Also: Calling #, Clid Auth

## Bit Inversion

Description: Specifies whether the MAX performs bit inversion when it sends or receives data over the WAN. Bit Inversion applies only to calls between codecs; it turns data 1s into 0s and data 0s into 1s. In some connections, you need to invert the data to avoid transmitting a pattern that the connection cannot handle. If you apply bit inversion, you should do so on both sides of the connection.

Note: If you are not certain about the requirements of bit inversion, contact your carrier.

Usage: Specify Yes or No. No is the default.

- Yes causes the MAX to perform bit inversion between two codecs.

- No does not modify the bit stream.

Example: Bit Inversion=No

Dependencies: You must set Bit Inversion to the same value on the calling and answering unit.

Location: `Host/Dual (Host/6) > PortN Menu > Directory`

## Block calls after

Description: Specifies how many unsuccessful attempts the Ascend unit will make before beginning to block outgoing calls.

Usage: Enter the number of connection attempts permitted before the Ascend unit blocks calls for the connection. The maximum number you can enter is 65535 (65535 attempts). The default is 0.

Location: `Session Options submenu of the Connection Profile.`

See Also: Blocked duration

## Blocked duration

Description: Specifies the length of time in seconds during which the Ascend unit will block outgoing calls.

Usage: Enter the number of seconds for the Ascend unit to block all calls made to the connection. When this period has elapsed, the unit will again allows calls to this connection.

Location: `Session Options submenu of the Connection Profile.`

See Also: Block calls after

See Also:

## BOOTP Relay Enable

Description: Specifies whether Bootstrap Protocol (BOOTP) requests are relayed to other networks. If you enable BOOTP relay, you must also specify the address of at least one BOOTP server in the Server parameter.

Usage: Specify Yes or No. No is the default.

- Yes enables the MAX to relay BOOTP requests to a server on another network.

- No disables BOOTP relay.

Example: BOOTP Relay Enable=Yes

Dependencies: For the BOOTP relay feature to work, DHCP Spoofing and SLIP BOOTP must be disabled.

Location: `Ethernet > Mod Config > BOOTP Relay`

See Also: Server

## Bridge

Description: Enables or disables link-level packet bridging for this connection. If you disable bridging, you must enable routing. Enabling bridging in the Answer profile enables the MAX to answer a call that contains packets other than the routed protocols (IP or IPX).

Usage: Specify Yes or No. No is the default.

- Yes enables the MAX to bridge packets across this connection based on the packet's destination MAC address (if specified in a Connection profile) or to answer incoming bridged connections (if specified in the Answer profile).

- No disables link-level bridging.

Example: Bridge=Yes

Dependencies: This parameter does not apply unless Bridging is enabled in the Ethernet profile. If you have a MAX running Multiband Simulation, Bridge is disabled.

Location: `Ethernet > Answer > PPP Options, Ethernet > Connections`

See Also: Bridging, Encaps, Route IP, Route IPX

## Bridging

Description: Enables or disables packet-bridging system-wide. It causes the MAX unit's Ethernet controller to run in promiscuous mode. In promiscuous mode, the Ethernet driver accepts all packets regardless of address or packet type and passes them up the protocol stack for a higher-layer decision on whether to route, bridge, or reject the packets.

Note: Running in promiscuous mode incurs greater processor and memory overhead than the standard mode of operation for the Ethernet controller. On heavily loaded networks, this increased overhead can result in slower performance, even if no packets are actually bridged.

Usage: Specify Yes or No. No is the default.

- Yes enables the MAX to bridge packets based on MAC addresses by running its Ethernet controller in promiscuous mode, which causes it to accept all packets regardless of packet type or address.

- No disables packet bridging and turns off promiscuous mode in the Ethernet controller.

Example: Bridging=Yes

Dependencies: If you have a MAX running Multiband Simulation, Bridging is disabled.

Location: `Ethernet > Mod Config`

See Also: Bridge

## Buffer Chars

Description: Specifies whether to buffer characters in a terminal server session or to process each character as it is received. If enabled, this feature causes the MAX to buffer input characters for 100 milliseconds.

Usage: Specify Yes or No. Yes is the default.

- Yes causes the MAX to buffer characters for 100 msecs in terminal server sessions.

- No causes the MAX to process each character as it is received.

Example: Buffer Chars=Yes

Dependencies: This parameter is not applicable when terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: Immed Telnet, TS Enabled

## Buildout

Description: Specifies the line buildout value for T1 lines with an internal CSU (Channel Service Unit). The buildout value is the amount of attenuation the MAX should apply to the line's network interface in order to match the cable length from the MAX to the next repeater.

Attenuation is a measure of the power lost on a transmission line or on a portion of that line. When you specify a build-out value, the MAX applies an attenuator to the T1 line, causing the line to lose power when the received signal is too strong. Repeaters boost the signal on a T1 line. If the MAX is too close to a repeater, you need to add some attenuation.

Usage: Check with your carrier to determine the correct value for this parameter. Specify one of the following values (db stands for decibels):

- 0-db (the default)

- 7.5-db

- 15-db

- 22.5-db

Example: Buildout=0

Dependencies: This parameter is not applicable if the T1 line does not have an internal CSU to connect to the local digital telephone system.

Location: `Net/T1 > Line Config > Line N`

## C

## Callback

Description: Enables or disables the callback feature. When you enable the callback feature, the MAX hangs up after receiving an incoming call that matches the one specified in the Connection profile. The MAX then calls back the device at the remote end of the link using the Dial # specified in the Connection profile.

You can use the Callback parameter to tighten security, as it ensures that the MAX always makes a connection with a known destination.

Usage: Specify Yes or No. No is the default.

- Yes enables the callback feature, causing the MAX to hang up and dial out the caller when it receives an incoming call that matches the Connection profile.

- No disables callback.

Example: Callback=Yes

Dependencies: This parameter does not apply to leased connections. If it is enabled on a switched connection, the Connection profile must both answer the call and call back the device requesting access. By the same token, any device calling into a Connection profile set for callback must be configured to both dial calls and answer them.

Location: `Ethernet > Connections > Telco Options`

## Call-by-Call

Description: In a T1 Line profile, specifies the call-by-call signaling value to set for routing calls from a local device through the MAX to the network. When it is set in another profile, it specifies the PRI service to use when placing a call using that profile.

Note: The Call-by-Call setting in the Dial Plan profile overrides the Call-by-Call setting in the Call profile and the Connection profile.

These are the call-by-call services available if the service provider is AT&T:

- 0 (Disable call-by-call service)

- 1 (SDN, including GSDN)

- 1 (VNET/Vision)

- 2 (800)

- 3 (PRISM1, PRISM II, WATS)

- 4 (900)

- 5 (DAL)

Usage: Specify a number between 0 and 65535, corresponding to the type of call-by-call service in use. The factory default is 0, which disables call-by-call service.

Example: Call-by-Call=6

Location: `Ethernet > Connections > Telco Options, System > Dial Plan, Ethernet > Frame Relay, Net/T1 > Line Config > Line N, Ethernet > X.25`

See Also: Call-by-Call N

## Call-by-Call N (N=1-6)

Description: In a Destination profile, specifies the PRI service to use when placing a call using the associated Dial #. For example, when the MAX dials the number specified by Dial 5#, the MAX uses the services specified by Call-by-Call 5.

Note: The setting of the Call-by-Call N parameter in the Destination profile overrides the setting of the Call-by-Call parameter in the Call profile or Connection profile.

These are the call-by-call services available if the service provider is AT&T:

- 0 (Disable call-by-call service)

- 1 (SDN, including GSDN)

- 2 (Megacom 800)

- 4 (900)

- 5 (DAL)

Usage: Specify a number between 0 and 65535, corresponding to the type of call-by-call service in use. The factory default is 0, which disables call-by-call service.

Example: Call-By-Call 1=4

Location: `System > Destinations`

See Also: Call-by-Call, Option

## Call Filter

Description: Specifies the number of a filter used to determine if a packet should cause the idle timer to be reset or a call to be placed. If both a call filter and data filter are applied to a connection, the MAX applies a call filter after applying a data filter. (Only those packets that the data filter forwards can reach the call filter.)

Usage: Specify a number between 0 and 199. The number you enter depends on the whether you are applying a filter you created using the vt100 interface, or a firewall you created using Secure Access Manager (SAM).

If you are applying a filter created using the vt100 interface, enter the last 2 digits of the filter number as it appears in the Filters menu.

If you are applying a firewall created with SAM, add 100 to the last 2 digits of the firewall number as it appears in the Firewalls menu. For example, if the number of your firewall is 90-601, specify 101. Refer to your SAM documentation for information on downloading firewalls to the MAX. The numbering scheme for filters and firewalls is:

- 0 indicates that no filtering is being used (this is the default)

- 1-99 indicates that a filter created using the vt100 interface is being used

- 100-199 indicates that a filter created using SAM is being used.

Example: Call Filter=7

Location: `Ethernet > Answer > Session Options, Ethernet > Connections > Session Options`

See Also: Data Filter, Filter

## Call Mode

Description: Specifies whether the MAX can initiate a call request on the X.25 IP connection.

Usage: Specify one of the following values:

- Incoming means the MAX does not issue a call request when data shows up for forwarding. If there is no virtual circuit established, the IP packet is dropped. If an incoming call is received from a host whose address matches the Answer X.121 address, the call is accepted.

- Outgoing means the MAX issues a call request to the Remote X.121 address when data shows up for forwarding. If there is no virtual circuit established and an incoming call request is received, the call is rejected.

- Both means the MAX accepts both incoming and outgoing call requests if the CUD indicates encapsulation that are supported. The called address must match the Answer X.121 address. If no virtual circuit is established and IP packets show up, a call request is issued to the Remote X.121 address.

Example: Call Mode=Both

Dependencies: This parameter applies only to X.25/IP connections. The setting relies on matching an address specified in the Answer X.121 or Remote X.121 address parameters.

Location: `Ethernet > Connections > Encaps Options`

See Also: Encaps, Answer X.121 Addr, Remote X.121 Addr

## Call Mgm

Description: Specifies the way that the MAX manages calls at an AIM port when AIM, FT1- AIM, FT1-B&O, or BONDING is the value for the Call Type parameter.

Depending upon the type of call in use, different call management features are available:

- AIM, FT1-B&O, and FT1-AIM calls

  For these types of calls, call management consists of remote management, online error monitoring, remote loopbacks, and online bandwidth control between codecs.

- BONDING calls

  For this type of call, call management consists of the remote loopback and online bandwidth control features only.

A remote loopback tests the entire connection from host interface to host interface, enabling the MAX to place a call to itself over the WAN and to send a user-specified number of packets over the connection. The data loops at the AIM port interface of the remote MAX, and comes back to the local MAX. The loopback tests the MAX unit's ability to initiate and receive calls, and diagnoses whether the connection over the digital access line and the WAN is sound.

For the call management features available by command, see Chapter 1, DO Command Reference.

Usage: Specify one of the following values:

- Manual (the default)

  This setting enables you to add or remove bandwidth manually during an AIM, FT1-B&O, or FT1-AIM call. When you choose Manual, the codec receives 99.8% of the bandwidth allocated for the T1 PRI line. The MAX uses the remaining 0.2% of bandwidth for AIM's management subchannel. For example, in a Manual call between codecs with a Base Ch Count of 5 and the Switched-56 data service, the host device receives approximately 279 kbps, or 99.8% of 280 kbps (5x56 kbps).

  If you have an FT1-B&O call online with manual call management, and the MAX has replaced the nailed-up channels with switched channels, the MAX does not automatically drop the switched channels when it restores the nailed-up channels.

- Delta

  This setting differs from Manual in that (a) you cannot add or subtract bandwidth while the call is online, and (b) the MAX provides the host with a different clock.

  When you set up AIM, FT1-B&O, and FT1-AIM calls, the AIM ports are synchronous and the WAN lines are synchronous. The AIM ports get a clock synchronized to the clock provided by the WAN. When you choose Delta, the MAX provides a clock that is an exact multiple of 64 kbps. Table 3-1 lists the host bandwidths available and the bandwidth that the network provides. The network values listed do not include the D channel when the signaling mode is ISDN.

  Table 3-1. Delta clock values

  #### Host bandwidth (in kbps) | #### Base Ch Count | #### Network bandwidth (in kbps) for 56k access | #### Network bandwidth (in kbps) for 64k access
  --- | --- | --- | ---
  1536 | 24 | 1568 | 1600
  1344 | 21 | 1400 | 1408
  1024 | 16 | 1064 | 1088
  768 | 12 | 784 | 832
  512 | 8 | 560 | 576
  384 | 6 | 392 | 448
  256 | 4 | 280 | 320

  The Host bandwidth is the bandwidth delivered to the codec. The Base Ch Count column specifies the Base Ch Count value needed to achieve this host bandwidth. However, the actual number of channels required for the host bandwidth is greater than the setting for Base Ch Count. Divide the value in the "Network bandwidth" columns by the data rate of the access line to arrive at the required number of channels.

- Dynamic

  This setting uses dynamic bandwidth allocation algorithms to automatically add or removes bandwidth during an AIM, FT1-B&O, or FT1-AIM call.

  The codec receives 99.8% of the bandwidth allocated for the T1 PRI line. The MAX uses the remaining 0.2% of the bandwidth for AIM's management subchannel. For example, in a Dynamic call between codecs with a Base Ch Count of 5 and the Switched-56 data service, the host device receives approximately 279 kbps, or 99.8% of 280 kbps (5x56 kbps).

  If you choose Dynamic and the MAX receives an incoming call set to Manual mode, the resulting connection is Dynamic for the answering device and Manual for the calling device. In all other cases, the incoming call determines call management in both directions. If you choose Dynamic, you must also specify the Add Pers, Dyn Alg, Sec History, and Sub Pers parameters in the Call profile.

- Static does not provide the ability to change bandwidth or resynchronize channels during an AIM, FT1-B&O, or FT1-AIM call; once the call is established, you cannot add or remove channels.

  When you choose Static, the host device gets a clock that is an exact multiple of 56 kbps or 64 kbps, and receives 100% of the bandwidth allocated from the network. For example, in a Static call with a Base Ch Count of 5 and the Switched-56 data service, the host device receives 280 kbps (5x56kbps).

- Mode 0 is required when the remote device (a) uses the BONDING inverse-multiplexing protocol and (b) is connected in dual-port mode to a videoconferencing codec.

  Inverse multiplexing is a method of combining individually dialed channels into a single, higher-speed data stream. A codec (COder/DECoder) is a device that encodes analog data into a digital signal for transmission over a digital medium. Typically, the MAX uses a videoconferencing codec that encodes and decodes video and audio information.

  In a dual-port call, a codec performs inverse multiplexing on two channels so that a call can achieve twice the bandwidth of a single channel. The codec provides two ports, one for each channel. Two AIM ports on the MAX connect a dual-port call to the codec; these ports are the primary port and the secondary port. Because the MAX places the two calls in tandem and clears the calls in tandem, it considers them a single call.

  In Mode 0, the user enters only the phone number of the primary host port associated with the remote codec. The remote BONDING device must have the secondary host port's phone number. No management subchannel exists, and the codec (not the MAX) performs the inverse multiplexing.

- Mode 1 uses the BONDING inverse-multiplexing protocol, provides the host device with a clock that is an exact multiple of 56 kbps or 64 kbps, and gives the host 100% of the bandwidth allocated from the network.

  For example, in a Mode 1 call with a Base Ch Count of 5 and the Switched-56 data service, the host device receives 280 kbps (5x56kbps).

  Mode 1 does not provide a management subchannel. This setting provides a subset of Static features.

- Mode 2 uses the BONDING inverse-multiplexing protocol; choose it when the codec does not require exact clocking.

  When you choose Mode 2, the codec receives 98.4% of the bandwidth allocated from the T1 PRI line, and uses a clock that is 98.4% of a multiple of 56 kbps or 64 kbps. The MAX constructs the BONDING management subchannel by using the remaining 1.6% of the bandwidth specified for the call with the Base Ch Count parameter. Mode 2 provides a subset of Manual features.

- Mode 3 uses the BONDING inverse-multiplexing protocol, provides the host device with a clock that is an exact multiple of 64 kbps, and uses a management subchannel.

  This setting provides a subset of Delta features. See Table 3-1 for a list of the host bandwidths available and the corresponding bandwidth that the network provides.

Dependencies: This parameter is not applicable if the call type is single channel or two-channel. The Dynamic setting is not applicable for Host/6 cards.

## Call Password

Description: Specifies the password for outgoing AIM or BONDING calls. Authentication is used only if the receiving unit has a password defined in the Port profile. If the Port profile in the receiving unit does not have a password defined, the units connect without authentication even though the originating unit may have sent parameters. Note that the MAX only authenticates AIM and BONDING calls; dual-port calls are not authenticated.

Usage: Enter a password of nine characters or less.

Example: Call Password=Ascend

Location: `Host/Dual (or Host/6) > Port N Menu > Directory`

See Also: Port Password

## Call Type

Description: Specifies a type of connection, or in the case of codecs, the architecture of the connection. These two different usages for this parameter are specified in two Usage sections below.

Usage: To specify the type of connection in a Frame Relay, Connection, or X.25 profile, specify one of these values:

- Nailed (a link that consists of nailed-up channels)

  This is the default for Frame Relay and X.25 profiles. You must specify which nailed channels to use in the Group or Nailed Grp parameter.

- Switched (a link that consists of switched channels)

  This is the default in a Connection profile.

- Nailed/MPP (nailed channels that may be augmented with switched channels if bandwidth is needed during an MP+ call)

  A Nailed/MPP connection is established when its nailed OR switched channels are connected end-to-end. The switched channels are dialed when the MAX receives an outbound packet for the far end and cannot forward it across the nailed connection, either because those channels are down or because they are being fully utilized.

  If both the nailed and switched channels in a Nailed/MPP connection are down, the connection does not reestablish itself until the nailed channels are brought back up or the switched channels are dialed. The maximum number of channels for the Nailed/MPP connection is either the Max Ch Count or the number of nailed channels in the specified group, whichever is greater. If a nailed channel fails, the MAX replaces that channel with a switched channel, even if the call is online with more than the minimum number of channels.

  The MAX must be the originator of the switched call. If you modify a Nailed/MPP Connection profile, most changes become active only after the call is brought down and then back up. However, if you add a group number (for example, changing Group=1,2 to Group=1,2,5) and save the modified profile, the additional channels are added to the connection without having to bring it down and back up.

- Perm/Switched (Connection profile only)

  A permanent switched connection is an outbound switched call that attempts to remain up at all times. If the unit or central switch resets or if the link is terminated, the permanent switched connection attempts to restore the link at 10-second intervals, which is similar to the way a nailed connection is maintained. A permanent switch connection conserves connection attempts but causes a long connection time, which may be cost effective for some customers. For the answering device at the remote end of the permanent switched connection, we recommend that the Connection profile be configured to answer calls but not originate them. If the remote device initiates a call, the MAX simply does not answer it. This situation could result in repeated charges for calls that have no purpose. To keep the remote device from originating calls, set AnsOrig to Ans Only for that device.

- D-channel (X.25 profile only)

  Specifies that the MAX supports X.25 over the D-channel.

Usage: To specify the architecture of an end-to-end connection between codecs (Call profiles), specify one of these values:

- AIM (Ascend Inverse Multiplexing)

  Inverse multiplexing is a method of combining individually dialed channels into a single, higher-speed data stream. The AIM setting is the default for units with the AIM option, and is not available on host ports not equipped with AIM functionality. Both ends of the call must have AIM-compatible equipment.

- 1 Chnl (single channel)

  The MAX uses a single channel to achieve the required bandwidth. The 1 Chnl setting is the default for units that do not have the AIM option. Use it to set up calls to terminal adapters, CSUs, or DSUs that do not have inverse multiplexing capability.

- 2 Chnl (dual-port)

  In a dual-port call, a codec performs inverse multiplexing on two channels so that a call can achieve twice the bandwidth of a single channel. The codec provides two ports, one for each channel. Two AIM ports on the MAX connect a dual-port call to the codec; these ports are the primary port and the secondary port. Because the MAX places the two calls in tandem and clears the calls in tandem, it considers them a single call.

  Use the 2 Chnl setting to set up calls to a codec that has a dual-port interface. The remote end of the link can be equipped with a TA (Terminal Adapter) or a DSU (Data Service Unit) that does not have inverse multiplexing capability.

- FT1-AIM

  The MAX combines nailed-up channels with switched channels to achieve the required bandwidth. This setting uses the AIM protocol, and is not available on host ports not equipped with AIM functionality. Both ends of the call must have AIM-compatible equipment. When the quality of a nailed-up channel falls to Marginal or Poor in an FT1-AIM call, the MAX drops the channel and does not replace it. The MAX cannot monitor these channels or restore them to an online call.

- FT1-B&O

  This setting provides automatic backup and overflow protection of nailed-up circuits. For this setting to appear in the menu of a Host/6 module, the current host port must be the primary port of a dual-port pair.

  - In providing backup bandwidth, the MAX drops all the nailed-up channels when the quality of a nailed-up channel falls to Marginal or Poor in an FT1-B&O call; the MAX then attempts to replace dropped nailed-up channels with switched channels.

  - It also monitors dropped nailed-up channels; when the quality of all dropped channels changes to Fair or Good, the MAX reinstates them. You must specify Call Mgm=Dynamic in order for the MAX to drop switched channels after restoring the nailed-up channels.

  - In providing overflow protection, the MAX supplies supplemental dial-up bandwidth during times of peak demand in order to prevent saturation of a nailed-up line.

  The circuit remains in place until the traffic subsides, and then it is removed.

  The FT1-B&O setting uses the AIM protocol, and is not available on host ports not equipped with AIM functionality. Both ends of the call must have AIM-compatible equipment. You must limit calls of this type to 28 channels.

- FT1

  This setting specifies a call consisting entirely of nailed-up channels. Use the FT1 setting to connect to terminal adapters, CSUs, or DSUs over fractional T1 or other nailed-up circuits. A fractional T1 circuit is a nailed-up connection to a T1 line with a bandwidth that might be only a fraction of the full T1 bandwidth. Contact your T1 line provider if you plan to use this call type with more than one line.

- BONDING

  The MAX combines 56-kbps or 64-kbps channels to achieve the required bandwidth. It can combine a maximum of 12 channels. This setting uses the BONDING (Bandwidth On Demand Interoperability Group) September 1992 1.0 specification. This setting is not available on host ports not equipped with AIM functionality. Calls using BONDING require BONDING-compatible equipment at both ends of the call.

Dependencies: A call type of Nailed makes parameters related to switched connections (such as callback) inapplicable, and a call type of Switched makes parameters related to nailed connections (such as the Group parameter) inapplicable. Because a call type of Perm/Switched is always outbound, the following parameters are inapplicable for permanent switched connections: AnsOrig, Callback, Idle, Backup.

The following parameters in the X.25 profile are not applicable when you set Call Type to D-Channel: Nailed Grp, Data Svc, PRI # Type, Dial #, Bill #, Call-by-Call, Transit #, LAPB T1, LAPB T2, LAPB N2, LAPB K, X.25 Seq Number Mode, X.25 Link Setup Mode, X.25 Node Type, X.25 Pkt Size, X.25 Min Pkt Size, X.25 Max Pkt Size

## Called #

Description: Specifies the number called to establish this connection, which is typically the number dialed by the far end. It is presented in an ISDN message as part of the call when DNIS (Dial Number Information Service) is in use. In some cases, the phone company may present a modified called number for DNIS. This number is used for authentication and to direct inbound calls to a particular device from a central rotary switch or PBX. See the MAX Security Supplement for details.

Usage: Specify the number to be used for Called Number authentication.

Example: Called #=5551234

Location: `Ethernet > Connections, Ethernet > Answer`

See Also: Id Auth

## Calling #

Description: Specifies the calling number (the far-end device's number). Many carriers include the calling number (the far-end device's number) in each call. Calling # is the caller ID number displayed on some phones and used by the MAX for CLID (Calling Line ID) authentication.

CLID authentication enables you to prevent the MAX from answering a connection unless it originates at the specified phone number. The number you specify in this parameter may also be used for callback security if you configure callback in the per-connection telco options.

Calling # is also used for callback security with CLID. See Callback.

Usage: Specify the called number to be used for authentication purposes.

Example: Calling #=555-6787

Location: `Ethernet > Connections, Ethernet > Answer`

See Also: Id Auth, Callback

## CBCP Enable

Description: Specifies how the MAX responds to caller requests to support CBCP.

Usage: Press Enter to cycle through the choices.

- Yes specifies the MAX will positively acknowledge, during LCP negotiations, support for CBCP.

- No specifies the MAX will reject any request to support CBCP.

  No is the default.

Location: `Ethernet > Answer > PPP Options

` See Also: CBCP Mode, CBCP Trunk Group

## CBCP Mode

Description: Specifies what method of callback the MAX offers the incoming caller.

Usage: Press Enter to cycle through the choices. You can specify one of the following settings:

#### Setting | #### Description
--- | ---
No Cback | Applies for Windows NT or Windows 95 clients who must not be called back. Because CBCP has been negotiated initially, the Windows clients must have validation from the MAX that no callback is used for this connection.
User Num | Specifies that the caller will supply the number the MAX uses for the callback.
Prof Num | Specifies the MAX will use the number in Ethernet > Connections > Any Connection profile > Dial # for the callback
User Num or No Cback | Specifies that the caller has the option of either supplying the number to dial or specifying that no callback is used for the call. If no callback is chosen, the call will not be disconnected by the MAX.

Dependencies: CBCP Mode applies only if CBCP is successfully negotiated for a connection. Encaps=PPP or MPP or MP.

Location: `Ethernet > Connections > Any Connection Profile > Encaps Options`

See Also: CBCP Enable, CBCP Trunk Group

## CBCP Trunk Group

Description: Assigns the callback to a MAX trunk group. This parameter is used only when the caller is specifying the phone number the MAX uses for the callback. The value in CBCP Trunk Group is prepended to the caller-supplied number when the MAX calls back.

Usage: Press Enter to open a text field. Then type a number from 4 to 9. The default is 9.

Dependencies: CPCP Trunk Group applies only if CBCP is negotiated for a connection. Encaps=PPP or MPP or MP.

Location: `Ethernet > Connections > Any Connection Profile > Encaps Options`

See Also: CBCP Enable, CBCP Mode

## Cell First

Description: Determines whether the MAX attempts a cellular connection before a land connection. When an incoming call is routed by the MAX to one of its digital modems, the modem answers the call by issuing an AT command string to the selected modem. This answer string contains the following command for support of cellular modems:

    sec=X,Y

where X is the parameter that selects whether the modem negotiates land-based or cellular first, and Y is the modem gain used for cellular communication. For example, if Cell First=No and Cell Level=18 is set in the TServ options menu, the command would be:

    -sec=0,18

Usage: Specify Yes or No. No is the default.

- Yes means a cellular connection is attempted first, followed by a land-based connection.

- No means a land-based connection is attempted first, followed by an attempt at a cellular connection.

Example: Cell First=No

Dependencies: This parameter is not applicable if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ options`

See Also: Cell Level

## Cell Level

Description: Specifies the modem cellular communications transmit and receive level. Valid values are -10 db through -18 db.

Usage: Specify one of the following values:

- 18 (the default)

- 17

- 16

- 15

- 14

- 13

- 12

- 11

- 10

Example: Cell Level=18

Dependencies: This parameter is not applicable if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ options`

See Also: Cell First

## Ch N (N=1-24, 1-32)

Description: Specifies the usage for this channel. Channel usage may be different from the usage specified for the line itself. For example, the line may specify switched usage while individual channels within that line specify nailed.

Usage: Specify one of the following values for T1 channels:

- Switched (the default). A switched channel supports switched connections. It may be robbed-bit or a B channel, depending on the line's signal mode.

- Nailed (a clear-channel 64k circuit).

- D channel (the channel used for ISDN D channel signaling). This is assigned automatically to channel number 24 on T1 lines when ISDN signaling is in use.

- Unused (unavailable for use).

- D&I (drop-and-insert), the channel drops through to the second T1 line, which typically supports a PBX.

- NFAS-Prime (the primary D channel for two NFAS lines).

- NFAS-Second (the secondary D channel for two NFAS lines). This channel is inactive unless the user activates it, or unless a failure of the primary D channel causes it to go online. This setting is optional.

Specify one of the following values for E1 channels:

- Switched (the default). A switched channel supports switched connections. It may be robbed-bit or a B channel, depending on the line's signal mode.

- Nailed (a clear-channel 64k circuit).

- D channel (the channel used for ISDN D channel signaling). This is assigned automatically to channel number 16 on E1 lines when ISDN signaling is in use.

- Unused (unavailable for use).

Example: Ch 1=Switched

Location: `Net/T1 > Line Config > Line N, Net/E1 > Line Config > Line N`

See Also: Sig Mode

## Ch N # (N=1-24, 1-32)

Description: You build multichannel calls (MP, MP+, AIM, BONDING) by specifying add- on numbers. A multichannel call begins as a single-channel connection to one phone number. The calling unit then requests additional phone numbers it can dial to connect those channels, and stores the add-on numbers it receives from the answering unit. The calling unit must integrate the add-on numbers with the phone number it dialed initially to add channels to the call. Three parameters specify add-on numbers: Ch N #, PRI Num and Sec Num.

Note: Do not enter phone numbers of the MAX you are calling in the Line Profile. The numbers you are calling belong in the Call and Connection profiles.

Typically, the phone numbers assigned to the channels share a group of leading (leftmost) digits. Enter only the rightmost digits identifying each phone number, excluding the digit(s) that are in common, as in the following example:

- If the add-on number in the called unit is shorter than the phone number dialed by the calling unit, only the rightmost digits are replaced.

  - For example, suppose you dial 777-3300 to reach channel 1of line 1 and 777-3331, 777-3332, through 777-3348, reaches other channels and other lines. In this case, set Ch1#=30 and the other channels and lines 31, 32, and so forth.

- If the add-on number is longer than the phone number dialed, the extra digits are discarded. For example:

  - Ch1# = 510-655-1212

  - Dial# = 555-1213

  - derived number for channel 1 = 655-1212

- If there is no add-on number, the derived number equals the dialed number.

  - Ch1# = (null)

  - Dial# = 555-1213

  - derived number for channel 1 = 555-1213

The most common reason multichannel calls fail to connect beyond the initial connection is that the answering unit sends the calling unit add-on numbers it cannot use to dial the other channels. The group of channels that make a multichannel call is called a bundle. A 10-channel bundle in which each channel is 64kbps, provides a 640 kbps connection.

Note: AIM and BONDING call bundles should not span dial plans. If you are receiving AIM or BONDING calls and have multiple dial plans, set up each dial plan as a separate trunk group. This also prevents MP and MP+ call bundles from spanning dial plans.

For example, you have two PRI lines from different service providers. You set the ChN Trnk Grp parameters for the first line to 9 and for the second line to 8. Also, enabling trunk groups on your MAX separates the two dial plans, and prevents the formation of bundles with channels from both PRI lines.

The phone numbers that you specify are the ones used to call this unit. There is a one-to-one correspondence between a phone number and a channel, except when you are using GloBanD lines. (When the switch type is GloBanD, the MAX pools the phone numbers and can apply them to any channel of the PRI line.)

Usage: Specify a phone number with a limit of 24 characters, which can include the following characters: 1234567890()[]!z-*#|. The default is null.

Example: Ch 1 #=1212

Dependencies: This parameter is applicable only for switched channels.

Location: `Net/T1 > Line Config > Line N, Net/E1 > Line Config > Line N`

See Also: Sub-Adr

## Ch N Prt/Grp (N=1-24, 1-32)

Description: Ch N Prt/Grp has two meanings, depending on a channel's configured usage. For switched channels, it specifies a port number to be used with the Ch N Slot parameter for call routing purposes. In effect, it reserves the channel for calls to and from that port. For nailed channels, it assigns a group number, which will be referenced from Call or Connection profiles to use the nailed channels for a connection.

Usage: Specify a number.

Dependencies: When specifying a port number for call routing purposes, you must also specify the slot number using Ch N Slot.

Example: Ch 1 Prt/Grp=5

Location: `Net/T1 > Line Config > Line N, Net/E1 > Line Config > Line N`

See Also: Ch N Slot, Group

## Ch N Slot (N=1-24, 1-32)

Description: Specifies a slot number to be used for call routing purposes. In effect, it reserves the channel for calls to and from that slot.

Usage: Specify one of the following values:

- 0 (Zero, the default). Zero means this parameter is not used to route incoming calls.

- 1 and 2 are invalid settings, because they represent the built-in slots containing T1 or E1 lines.

- 3 through 8 represent expansion slots. When looking at the back panel of the MAX unit, slot #3 is the bottom slot in the left bank of slots, followed by #4 and #5 in ascending order. Slot #6 is the bottom right slot, followed by #7 and #8 in ascending order.

- 9 represents the LAN. Calls are routed to the bridge/router module.

Dependencies: This parameter is applicable only for switched channels.

Example: Ch 1 Slot=7

Location: `Net/T1 > Line Config > Line N, Net/E1 > Line Config > Line N`

See Also: Ch N Prt/Grp

## Ch N Trnk Grp (N=1-24, 1-32)

Description: Assigns a channel to a trunk group, making it available for outbound calls. Dial numbers for connections can then be directed to specific channels by specifying the trunk group as a single-digit dialing prefix to the far-end phone number.

Usage: Specify a number between 4 and 9 for each trunk group. The default is 9.

Dependencies: This parameter applies only when trunk groups have been enabled in the System profile.

Location: `Net/T1 > Line Config > Line N, Net/E1 > Line Config > Line N`

See Also: Use Trunk Grps

## Circuit

Description: Specifies an alphanumeric name for a DLCI endpoint. When combined as a circuit, the two DLCI endpoints act as a tunnel-data received on one DLCI bypasses the Ascend router and is sent out on the other DLCI.

A circuit is a permanent virtual circuit (PVC) segment that consists of two DLCI end points and possibly two Frame Relay profiles. It requires two and only two DLCI numbers: data is dropped if the circuit has only one DLCI and if more than two are defined, only two are used. Circuits are defined in two Connection profiles. Data coming in on the DLCI configured in the first Connection profile is switched to the DLCI configured in the second one.

Usage: Specify a name for the circuit, up to 16 characters. The other end-point of the PVC must specify the same name in its Circuit configuration.

Example: Circuit=circuit-1

Dependencies: This parameter applies only to FR_CIR-encapsulated calls.

Location: `Ethernet > Connections > Encaps options`

See Also: Encaps

## Clear

Description: Specifies whether the control-line state determines when the MAX clears a call.

Usage: Specify one of the following values:

- Terminal (clear the call manually by using DO 2). This is the default.

- DTR Active (clear the call only if DTR is asserted at the port, indicating that the codec is ready to receive data).

- DTR Inactive (clear the call when DTR becomes inactive, indicating that the codec is not ready to receive data).

- RTS Inactive (clear the call when RTS becomes inactive, indicating that the codec does not have data to send).

- RTS Active (clear the call when RTS is asserted, indicating that the codec is ready to send data).

Dependencies: If the Answer or Dial parameter is set to RS-366, V.25 bis, or X.21, set Clear to DTR Inactive unless your application requires otherwise. This setting is compatible with the CCITT recommendation for the V.25 bis and X.21 protocols, and with most implementations of RS-366 dialing.

Location: `Host/Dual (Host/6) > PortN Menu > Port Config`

See Also: Answer, Dial

## Clear Call

Description: Specifies whether the dial-in connection is cleared when an interactive Telnet, Rlogin, or TCP session terminates. If set to No, the user is returned to the terminal server menu when the Telnet, Rlogin, or TCP session terminates.

Usage: Specify Yes or No. The default is No.

- Yes means the MAX clears the call when a Telnet, Rlogin, or TCP session terminates.

- No means the MAX returns the user to the terminal server menu when a Telnet, Rlogin, or TCP session terminates.

Example: Clear Call=Yes

Dependencies: This parameter is not applicable when terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

## Client

Description: Enables the MAX to respond to multicast clients on the local Ethernet. Clients cannot be support on the MBONE interface, so this means that the multicast router resides across a WAN link.

Usage: Specify Yes or No. No is the default.

- Yes means the MAX begins handling IGMP client requests and responses on the interface. It does not begin forwarding multicast traffic until the rate limit is set. The Rate Limit parameter specifies the rate at which the MAX accepts multicast packets from its clients. It does not affect the MBONE interface.

- No means the MAX does not handle IGMP client requests and responses on the interface.

Example: Client=Yes

Dependencies: This parameter is not applicable if Multicast Forwarding is disabled or if the local Ethernet is the MBONE interface (supporting a multicast router).

Location: `Ethernet > Mod Config > Multicast`

See Also: Multicast Forwarding, Mbone profile

## Client #N (N=1-9)

Description: Specifies up to nine IP address of clients permitted to make RADIUS requests. Each client address can support a range of addresses instead of a single client IP address, for example:

- Client #1= 125.65.5.0/24

  This enables RADIUS requests from any hosts on the 125.65.5 subnet.

- Client #2= 125.5.0.0/16

  This enables RADIUS requests from any hosts on the 125.5 subnet.

- Client #3= 135.50.248.76/32

  This enables requests from the host whose address is 138.50.248.76.

Note: If no mask bits are supplied, the software supplies a default netmask based on the class of the address.

Usage: Specify an IP address. The default is 0.0.0.0, which disables the associated client field. At least one of the fields must contain an IP address other than 0.0.0.0 for the server to be active.

Dependencies: This parameter does not apply if the on-board RADIUS server is disabled.

Location: `Ethernet > Mod Config > RADIUS Server`

See Also: Server, Server Key, Server Port, MAX RADIUS Configuration Guide

## Client Assign DNS

Description: Specifies whether client DNS server addresses will be presented while this connection is being negotiated.

Usage: Specify Yes (to use client DNS servers) or No. No is the default.

Example: Client Assign DNS = no

Location: `Ethernet > Connections > IP Options`

See Also: Client Pri DNS, Client Sec DNS

## Client Gateway

Description: Specifies a connection-specific default route to be used for forwarding packets received on this connection. The MAX uses this default route instead of the system-wide Default route in its routing table. This route is connection-specific, so it is not added to the routing table.

Note: The MAX must have a direct route to the address you specify.

Usage: Specify the IP address of a next-hop router. The default value is 0.0.0.0; if you accept this value, the Ascend unit routes packets as specified in the routing table, using the system- wide default route if it cannot find a more specific route.

Example: Client Gateway=10.1.2.3

Location: `Ethernet > Connections > IP Options`

## Client Pri DNS

Description: Specifies a primary DNS server address to be sent to any client connecting to the MAX. Client DNS has two levels: a global configuration that applies to all PPP connections, and a connection-specific configuration that applies to that connection only. The global client addresses are used only if none are specified in the Connection profile. You can also choose to present your local DNS servers if no client servers are defined or available.

Usage: Specify the IP address of a DNS server to be used for all connections that do not have a DNS server defined. The default value is 0.0.0.0.

Example: Client Pri DNS=10.9.8.7/24

Location: `Ethernet > Mod Config > DNS, Ethernet > Connections > IP Options`

## Client Sec DNS

Description: Specifies a secondary DNS server address to be sent to any client connecting to the MAX. Client DNS has two levels: a global configuration that applies to all PPP connections, and a connection-specific configuration that applies to that connection only. The global client addresses are used only if none are specified in the Connection profile. You can also choose to present your local DNS servers if no client servers are defined or available.

Usage: Specify the IP address of a secondary DNS server to be used for all connections that do not have a DNS server defined. The default value is 0.0.0.0.

Example: Client Sec DNS=10.9.8.7/24

Location: `Ethernet > Mod Config > DNS, Ethernet > Connections > IP Options`

## Clock Source

Description: Specifies whether the T1 or E1 line may be used as the clock source for timing synchronous transmissions. If it is enabled, the line provides timing as long as it is active and not in Red Alarm mode, and the MAX runs in recovered loop timing mode. If the MAX connects to more than one line, selecting Yes for each one gives the MAX the option of using any of the lines as a source of synchronous timing.

Usage: Specify Yes or No. Yes is the default, and is the proper setting for normal operations.

- Yes means the line may be used as the clock source for timing synchronous transmissions.

- No means the line may not be used as the clock source. When this setting is disabled, the MAX uses another line for timing or uses its internal clock. This is recommended only when two MAX units connect to each other by a crossover cable (with optional T1 repeaters) between their network ports

Example: Clock Source=Yes

Location: `Net/T1 > Line Config > Line N, Net/E1 > Line Config > Line N`

## Clr Scrn

Description: Specifies whether the screen is cleared when a terminal server session begins.

Usage: Specify Yes or No. Yes is the default.

- Yes means the MAX clears the screen when a terminal server session begins.

- No means the MAX does not clear the screen.

Example: Clr Scrn=Yes

Dependencies: This parameter is not applicable when terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: TS Enabled

## COMB

Description: Specifies whether the MAX accepts or rejects incoming calls that use Combinet encapsulation and meet all other Answer profile criteria. Combinet requires authentication by password and MAC address.

Usage: Specify Yes or No. Yes is the default.

- Yes means the MAX will answer inbound Combinet calls, provided that they meet all other connection criteria.

- No means the MAX will not answer inbound calls from a Combinet bridge.

Dependencies: This parameter is not applicable unless bridging is enabled system-wide in the Ethernet profile.

Location: `Ethernet > Answer > Encaps`

See Also: Bridge, Bridging, Encaps

## Comm

Description: Specifies the SNMP community name associated with the SNMP PDU (Protocol Data Units). The string you specify becomes a password that the MAX sends to the SNMP manager when an SNMP trap event occurs. The password authenticates the sender identified by the host address.

Usage: Specify the community name, up to 31 characters. The default is public.

Example: Comm=Ascend

Dependencies: If this parameter and the Dest parameter are null, the MAX does not generate SNMP traps.

Location: `Ethernet > SNMP Traps`

See Also: Dest

## Compare

Description: Specifies the type of comparison to make between the specified value in a filter and the specified location in the contents of a packet.

Usage: Specify one of the following values:

- Equals means the filter matches the packet when the specified value and the packet contents are equal. This is a default.

- NotEquals means the filter matches the packet when the specified value and the packet contents are equal.

Dependencies: This parameter does not apply if the filter is not Valid or if the filter type is IP.

Location: `Ethernet > Filters > Input filters > In filter N > Generic, Ethernet > Filters > Output filters > Out filter N > Generic`

See Also: Length, Mask, Offset, Value, Valid

## Compression

Description: Enables or disables data compression on or off for a Combinet link. Both sides of the link must enable compression for the algorithm to have any effect.

Usage: Specify one of the following values:

- None (the default in the Answer profile)

- Stac (Use an Ascend modified version of draft 0 of the CCP protocol)

- Stac-9 (Use draft 9 of the Stac LZS Compression protocol)

- MS-Stac

  Use Microsoft/Stac compression (the same method as Windows95). If the caller does not acknowledge Microsoft/Stac compression, the MAX attempts to use standard Stac compression; if that does not work, it uses no compression.

Dependencies: This parameter is applicable only for Combinet connections. Both sides of the link must enable compression for the algorithm to have any effect.

Location: `Ethernet > Answer > COMB Options, Ethernet > Connections > Encaps Options`

See Also: Link Comp

## Connection #

Description: Specifies the number of a Connection profile needed to bring up a bridged or routed connection. The MAX uses this number to locate the profile and bring up the connection needed to forward packets whose destination address is not on the local network.

If it receives a packet whose destination MAC address is not on the local Ethernet, it looks in the bridging table for a matching MAC address and uses the specified Connection profile to bring up a bridged connection.

If it receives an IPX packet whose destination address is not on the NetWare LAN, it checks its IPX routing table and uses the specified Connection profile to bring up an IPX connection.

Note: The number of a Connection profile is the unique portion of the number preceding the profile's name in the Connections menu.

Usage: Specify a Connection profile number.

Dependencies: Bridge profiles are not used for connections that enable dial-on-broadcast.

Location: `Ethernet > Bridge Adrs, Ethernet > IPX Routes`

See Also: Dial Brdcast, Route IPX

## Console

Description: Specifies the interface established at the vt100 port labeled Control on the back panel of the MAX.

Usage: Specify one of the following values:

- Standard means the standard set of edit menus comes up in the vt100 window at system startup. This is the default.

- MIF means MIF (Machine Interface Format) is accessible at system startup. From the MIF interface you can display the edit menus by pressing Ctrl-C, and return to MIF again by using the Use MIF command.

- Limited means a set of simplified menus comes up, useful for operating AIM ports (but not for bridging or routing). To enter or exit the simplified menus, press Ctrl-T.

Dependencies: You cannot operate MIF through a hand-held terminal. Only a vt100 terminal or emulator can operate MIF.

Location: `System > Sys Config`

## Contact

Description: Specifies the person or department to contact to report error conditions. This field is SNMP readable and settable.

Usage: Specify the name of the contact person or department. You can enter up to 80 characters.

Example: Contact=rchu

Location: `System > Sys Config`

See Also: Location

## Cost

Description: Specifies the cost of an OSPF link. The cost is a configurable metric that must take into account the speed of the link and other issues. The lower the cost, the more likely the interface will be used to forward data traffic.

With the exception of links to stub networks, the output cost must always be non-zero. A link with a cost of 0xFFFFFF (16777215) is considered non-operational.

In a static route, the interpretation of this cost depends on the type of external metrics set in the ase-type parameter. If the MAX is advertising type 1 metrics, OSPF can use the specified number as the cost of the route. Type 2 external metrics are an order of magnitude larger. Any type 2 metric is considered greater than the cost of any path internal to the AS (autonomous system).

Usage: Specify a number greater than 0 and less than 16777215. The default is 1 on the Ethernet interface and 10 on the WAN links.

Example: Cost=50

Location: `Ethernet > Connections > OSPF Options, Ethernet > Mod Config > OSPF Options`

## CUG Index

Description: Specifies the closed user group (CUG) index/selection facility to use in the next call request. The closed user group selection/index facility is used to indicate to the called switch the closed user group selected for a virtual call.

Usage: Specify the CUG Index to use in the next call request. You can specify up to two digits. The default is null.

Dependencies: Encaps must be set to X25/PAD for CUG Index to be applicable.

## D

## Data Filter

Description: Specifies the number of a filter used to determine if packets should be forwarded or dropped. If both a call filter and data filter are applied to a connection, the MAX applies a call filter after applying a data filter. (Only those packets that the data filter forwards can reach the call filter.)

Usage: Specify a number between 0 and 199. The number you enter depends on the whether you are applying a filter you created using the vt100 interface, or a firewall you created using Secure Access Manager (SAM).

If you are applying a filter created using the vt100 interface, enter the last 2 digits of the filter number as it appears in the Filters menu.

If you are applying a firewall created with SAM, add 100 to the last 2 digits of the firewall number as it appears in the Firewalls menu. For example, if the number of your firewall is 90-601, specify 101. Refer to your SAM documentation for infomation on downloading firewalls to the MAX. The numbering scheme for filters and firewalls is:

- 0 indicates that no filtering is being used (this is the default)

- 1-99 indicates that a filter created using the vt100 interface is being used

- 100-199 indicates that a filter created using SAM is being used.

When you set Data Filter to 0 (zero), the MAX forwards all data packets.

Example: Data Filter=7

Location: `Ethernet > Answer > Session Options, Ethernet > Connections > Session Options`

See Also: Call Filter, Filter

## Data Format

Description: Specifies the data format and parity checking/generation behavior of the PAD when it validates opening frames as well as during Local mode data transfer.

Usage: Specify one of the following values:

- 7-E-1 (the default)

  Specifies that the PAD uses 7 data bits, even parity, and 1 stop bit during opening frame validation and local mode data transfer.

- 7-O-1

  Specifies that the PAD uses 7 data bits, odd parity, and 1 stop bit during opening frame validation and local mode data transfer.

- 7-M-1

  Specifies that the PAD uses 7 data bits, mark parity, and 1 stop bit during opening frame validation and local mode data transfer.

- 7-S-1

  Specifies that the PAD uses 7 data bits, space parity, and 1 stop bit during opening frame validation and local mode data transfer.

- 8-N-1

  Specifies that the PAD uses 8 data bits, no parity, and 1 stop bit during opening frame validation and local mode data transfer.

Dependencies: This parameter is always applicable.

Location: `Ethernet > Connections > any Connection profile > Encaps options
Ethernet > Answer > T3POS options`

## Data Svc

Description: A data service is provided over a WAN line and is characterized by the unit measure of its bandwidth. A data service can transmit either data or digitized voice. In a Call profile, Connection profile, X.25, or Frame Relay profile, Data Svc specifies the type of data service the link uses. In a Dial Plan profile, Data Svc specifies the data service associated with the number the MAX dials under the extended dial plan.

Note: Either party can request a data service that is unavailable. In this case, the MAX cannot connect the call.

Usage: Specify one of the following values:

- 56K

  The call contains any type of data and connects to the Switched-56 data service. The only services available to lines using inband signaling (T1 or E1 lines containing one or more switched channels, and Switched-56 lines) are 56K and 56KR.

- 56KR

  The call contains restricted data, guaranteeing that the data the MAX transmits meets the density restrictions of D4-framed TI lines, and connects to the Switched-56 data service. The only services available to lines using inband signaling (T1 or E1 lines containing one or more switched channels, and Switched-56 lines) are 56K and 56KR.

- 64K

- The call contains any type of data and connects to the Switched-64 data service. Data services above 64 kbps are not valid for a BONDING call.

- Voice (digital voice call)

  The call is an end-to-end digital voice call for transporting data when a switched data service is not available. If you choose this setting, the data may become unusable unless you meet these technical requirements:

  - Use only digital end-to-end connectivity; no analog signals should be present anywhere in the link.

  - Make sure that the phone company is not using any intervening loss plans to economize on voice calls.

  - Do not use echo cancellation; analog lines can echo, and the technology to take out the echoes can also scramble data in the link.

  - Do not make any modifications that can change the data in the link.

- Modem (digital modem call)

  The call uses a digital modem. If no digital modems are available, the call is not placed. The data rate depends upon the quality of the connections between modems and the types of modems used. This setting requires that your MAX have digital modems installed. Modem applies only when Encaps=MPP, PPP or X.25/PAD. Currently, multichannel modem calls are not supported even if Encaps=MPP.

- V.110 bit-rate data-service (V.110 terminal adapter call)

  The call uses a v.110 terminal adapter, using the PPP protocol at the specified bit rate over the specified data service line. The bit-rate may be one of the following:

  - 2.4

  - 4.8

  - 9.6

  - 19.2

  - 38.4

  The data-service may be one of the following:

  - 56K (switched-56)

  - 56KR (restricted switched-56)

  - 64K (switched-64)

  If the MAX cannot sync up with the remote terminal adapter using the specified bit rate, it attempts to use one of the other four bit rates.

- Inherit (use the data service requested by the local calling device)

  This setting is available only in Dial Plan profiles. The call connects with the data service as requested by the caller on the local Host/BRI line. If Data Svc is not set to Inherit in the Dial Plan profile, the setting in the Dial Plan profile overrides the settings in the Call profile and Connection profile.

- 384K/H0 (switched-384)

  This setting is available only in Call profiles. It means that the call contains any type of data and connects to the Switched-384 data service. This AT&T data service does not require MultiRate or GloBanD. A Host/6 expansion module supports a maximum of four 384K/H0 calls.

- 384KR (restricted switched-384)

  This setting is available only in Call profiles. It means that the call contains restricted data and connects to MultiRate or GloBanD data services at 384 kbps.

- 1536K (switched-1536)

  This setting is available only in Call profiles. It means that the call contains any type of data and connects to the Switched-1536 data service at 1536 kbps. This setting is valid only for lines using NFAS signaling.

- 1536KR (restricted switched-1536)

  This setting is available only in Call profiles. It means that the call contains restricted data and connects to the Switched-1536 data service at 1536 kbps. This setting is valid only for lines using NFAS signaling.

- 128K, 192K, 256K, and other multiples of 64K (multi-rate)

  This setting is available only in Call profiles. These values are available on a PRI line with MultiRate or GloBanD data services. If the MAX has the MultiRate option, these data services appear.

Dependencies: Because FT1 calls do not include switched services, the Data Svc parameter lists only 56KR and 64K when Call Type=FT1; in this context, the Data Svc setting indicates how much bandwidth the MAX routes to the host for each channel in the connection. When Call Type=FT1-B&O or Call Type=FT1-AIM, the Data Svc parameter refers to the switched channels.

## Date

Description: Specifies the month, day, and year. You should set this parameter when installing the MAX.

Usage: Specify the current date in the format <month > /<day > /<year >. The default is 00/ 00/00.

Location: `System > Sys Config`

## DBA Monitor

Description: Specifies how the MAX monitors the traffic over an MP+ connection. Only the initiating side of the call can add or subtract bandwidth. If both sides of the link have DBA Monitor set to None, Dynamic Bandwidth Allocation is disabled.

Usage: Specify one of the following values:

- Transmit

  This setting specifies that the MAX adds or subtracts bandwidth based on the amount of data it transmits.

  Transmit is the default.

- Transmit-Recv

  This setting specifies that the MAX adds or subtracts bandwidth based on the amount of data it transmits and receives.

- None

  This setting specifies that the MAX does not monitor traffic over the link.

Dependencies: DBA Monitor is only supported on MP+ calls.

Location: `Ethernet > Connections > Encaps Options`

## DCE Addr

Description: Specifies the address of the calling unit in the EU-UI header of packets that the calling unit sends.

Usage: Specify the DCE address. Contact your service provider for the correct address.

Dependencies: This parameter applies only to EU-UI connections.

Location: `Ethernet > Connections > Encaps Options`

See Also: DTE Addr, Encaps

## DCE N392

Description: Specifies the number of errors during DCE N393 monitored events which causes the network side to declare the user side procedures inactive.

Usage: Specify a value between 1 and 10 that is less than DCE N393.

Example: DCE N392=5

Dependencies: This parameter is N/A when FR Type is DTE.

Location: `Ethernet > Frame Relay`

## DCE N393

Description: Specifies the DCE monitored event count (between 1 and 10).

Usage: Specify a value between 1 and 10 that is greater than DCE N392.

Example: DCE N393=7

Dependencies: This parameter is N/A when FR Type is DTE.

Location: `Ethernet > Frame Relay`

## DeadInterval

Description: Specifies the number of seconds the MAX will wait before declaring its neighboring routers down after it stops receiving the router's Hello packets.

Usage: Specify a number. In a Connection profile, the default is 120 seconds. In the Ethernet profile, the default is 40 seconds.

Example: DeadInterval=240

Location: `Ethernet > Connections > OSPF Options, Ethernet > Mod Config > OSPF Options`

See Also: HelloInterval

## Dec Ch Count

Description: Specifies the number of channels the MAX removes as a bundle when bandwidth changes either manually or automatically during a call. You cannot clear a call by decrementing channels

If the data service is 384K/H0 or 384KR, this value should be divisible by 6, because 384 kbps is 6x64 kbps. If the data service is MultiRate or GloBanD and the service you select is a multiple of 64 kbps, this value should be a multiple of 6.

Usage: Specify a number between 1 and 32. The default is 1.

Example: Dec Ch Count=1

Dependencies: This parameter does not apply if all channels of a link are nailed up. In a Call profile, this parameter applies only if the Call Type parameter is set to AIM, FT1-AIM, FT1- B&O, or BONDING and if Call Mgm parameter is set to Manual, Dynamic, or Mode 2.

Location: `Host/Dual (Host/6) > PortN Menu > Directory, Ethernet > Connections > Encaps Options`

See Also: Base Ch Count, Inc Ch Count, Max Ch Count

## Default Zone

Description: Specifies the default zone for nodes on an AppleTalk seed router's internet. All AppleTalk nodes on the seceded network use the default zone until a user explicitly selects a different zone name. A zone is a multicast address containing an arbitrary subset of the AppleTalk nodes in an internet. Each node belongs to only one zone, but a particular extended network can contain nodes belonging to any number of zones. Zones provide departmental or other groupings of network entities that a user can easily understand.

Usage: Enter a zone name of up to 33 alphanumeric characters.

In an Ascend AppleTalk router, zone names are not case sensitive. However, some routers regard zone names as case sensitive, and you should be consistent in spelling zone names when you configure multiple connections or routers. Although AppleTalk permits the use of spaces in zone names, it does not consider an underscore to be the same as a space. Since some routers do equate the underscore and the space, or do not recognize a space as a valid character, it is advisable to use only the underscore in a network with routers other than Ascend routers.

Example: Default Zone=SALES

Dependencies: You must select the following:

- AppleTalk=Yes (in Ethernet > Mod Config)

- Route AppleTalk=Yes in the Connection profile

- Route AppleTalk=Yes in the Connection profile (if the connection requires authentication using names and passwords)

- values for the remaining parameters in the AppleTalk Options submenu

Location: `Ethernet > Mod Config > AppleTalk Options

` See Also: AppleTalk, Route AppleTalk, AppleTalk Router, Zone Name #n, Net Start, Net End, Peer (AppleTalk Options)

## Def Telnet

Description: Specifies whether the MAX will interpret a command that does not include a keyword as a hostname for a Telnet command. To display the terminal server command keywords, enter help or a question mark (?) from the terminal server command-line interface.

Usage: Specify Yes or No. Yes is the default.

- Yes specifies that the MAX interprets any terminal server command that does not begin with a keyword as though it began with the keyword Telnet. (That is, it interprets the string typed at the prompt as a Telnet hostname.)

- No specifies that all terminal server commands must begin with a keyword.

Example: Def Telnet=Yes

Location: `Ethernet > Mod Config > TServ Options`

## Delay Dual

Description: Specifies whether the MAX inserts a ten-second delay between dialing the first and second calls in a dual-port call.

In a dual-port call, a codec performs inverse multiplexing on two channels so that a call can achieve twice the bandwidth of a single channel. Inverse multiplexing is a method of combining individually dialed channels into a single, higher-speed data stream.

The codec provides two ports, one for each channel. Two AIM ports on the MAX connect a dual-port call to the codec; these ports can be the V.35, RS-499, or X.21 ports on the MAX, and are called the primary port and the secondary port. Because the MAX places the two calls in tandem and clears the calls in tandem, it considers them a single call.

Usage: Specify Yes or No. No is the default.

- Yes specifies that the MAX waits ten seconds before dialing the second call in a dual-port call.

- No specifies that the MAX places both calls at the same time.

Example: Delay Dual=Yes

Location: `System > Sys Config`

## Delete Digits

Description: Specifies the number of digits deleted from the beginning of the phone number dialed by the device connected to line #2. Typically, a PBX (Private Branch Exchange) is connected to line #2. A PBX is an internal telephone network in which one incoming number directs calls to various extensions and from one office to another.

Use this parameter when the PBX used to be connected to a switch that supplied a T1 line, and that line is now supplied by the MAX. The PBX has to change the numbers it dials. The Delete Digits parameter converts the number the PBX dials to the number presented to the WAN switch.

Usage: Specify the number of digits to delete from the beginning of the phone number. You should specify the number of digits received from the PBX specific to the T1 switch the MAX is emulating.

Example: Delete Digits=2

Dependencies: This parameter applies only to T1 lines using PBX-T1 conversion.

Location: `Net/T1 > Line Config > Line N`

See Also: Sig Mode

## Dest

Description: In a Route profile, Dest specifies the route's target IP address. This is the destination address that will cause the MAX to bring up this route. In a Route profile, the default null address indicates the default route, used for all destinations that have no explicit route in the routing table.

In an SNMP Traps profile, Dest is the IP address to which the MAX sends traps (the IP address of the station running an SNMP management utility). The default null address means that no traps are sent. If the Comm parameter is also null, traps are turned off altogether.

Usage: Specify the destination IP address. The default value is 0.0.0.0/0.

Example: Dest=10.207.23.1

Dependencies: This parameter does not apply if the MAX does not support IP routing.

Location: `Ethernet > Static Rtes, Ethernet > SNMP Traps`

See Also: Gateway

## Dial

Description: Specifies how a call originates at the port. In addition to dialing through the MAX unit's user interface, you can use one of three dialing protocols to dial from the AIM port. These protocols are RS-366, V.25 bis, and X.21.

Note: The Dial parameter setting does not prevent you from dialing manually.

Usage: Specify one of the following values:

- Terminal (the default) specifies that the MAX dials calls only when the user enters the DO 1 or Ctrl-D-1 (DO Dial) command.

- DTR Active specifies that the MAX dials the number in the current Call profile when the DTR signal is asserted at the port.

  An AIM port uses pins for controlling the data flow through the port. A device sends a signal through a pin and over the line to another device; the signal being sent determines the control-line state. For example, a device can send a signal to inform another party that it is ready to receive data; in this case, the control-line state is DTR (Data Transmit Ready). The process of sending control signals is called handshaking.

  When the device connected to the MAX unit's AIM port is ready to receive data, it sends an electrical signal over the DTR line to the MAX. When this signal is on, DTR is asserted.

- RS-366 ext1 specifies that the MAX dials calls through an RS-366 dialing service.

  The RS-366 dialing interface on the MAX meets the EIA RS-366 specification for dialing individual calls from an AIM port.

- RS-366 ext2 supports RS-366 dialing, but has different message protocols than RS-366.

  If you choose this setting, you must also configure the RS-366 Esc parameter.

- V.25bis specifies that V.25 bis handshaking controls dialing from your AIM port module.

  The V.25 bis dialing interface on the MAX meets the V.25 bis CCITT recommendation for the addressed call mode of dialing and answering local calls. This interface enables direct dialing and answering from an AIM port that uses the V.25 bis dialing protocol. The MAX unit's implementation of V.25 bis conforms to the extension of this standard published by Cisco Systems and Ascend Communications, Inc.

  The port must support AIM functionality for this setting to have any effect. V.25bis does not appear if you have paired the port with another one using the Dual Ports parameter in the Host-Interface profile.

- V.25bis-C is identical to V.25bis, except that the CTS (Clear To Send) signal does not change its state during a call.

- X.21 ext1 specifies that the MAX dials calls under the control of the AIM port module as described in the CCITT Blue Book Rec. X.21.

  The X.21 dialing interface on the MAX is often used for direct dialing and answering from an attached codec, router, or other codec.

- X.21 ext1-P uses the same protocol as X.21 ext1, and is required when you are using a PictureTel X.21 dialer.

- X.21 ext2 supports x.21 dialing, but has different message protocols than X.21 ext1.

` See Also: RS-366 Esc

## Dial #

Description: Specifies the number used to dial out this connection. It can contain up to 24 characters, which may include a dialing prefix that directs the connection to use a trunk group or dial plan; for example: 6-1-212-555-1212.

In Call profiles, if the call type specifies a two-channel call, you can specify two phone numbers to total up to 49 characters. The two numbers must be separated by an exclamation mark, for example: 5551212!5551234

Note: The phone number may contain a subaddress or trunk-group number. If the use of trunk groups is enabled in the System profile, this parameter must specify a trunk group as the first digit.

Usage: Specify a phone number up to 24 characters. The MAX sends only the numeric characters to place a call. You must limit the number to these characters: 1234567890()[]!z-*#|

Example: Dial #=6-1-808-555-1212

Dependencies: This parameter is inapplicable for leased connections or connections using Frame Relay encapsulation.

Location: `Host/Dual (Host/6) > PortN Menu > Directory, Ethernet > Connections, Ethernet > Frame Relay, Ethernet > X.25`

See Also: B1 Trnk Grp, B2 Trnk Grp, Call Type, Ch N Trnk Grp, Dial Plan, Encaps, Sub-Adr, Use Trunk Grps

## Dial N# (N=1-6)

Description: Specifies the phone numbers that reach the destination of the profile.

Usage: Specify a phone number for each Dial N# parameter. You can enter up to 24 characters, and you must limit those characters to the following:

    1234567890()[]!z-*#|

The MAX sends only the numeric characters to place a call. The default value is null.

In a Call profile, when Call Type=2 Chnl, the Dial N# parameter accepts a single telephone number containing up to 49 characters, or two phone numbers containing up to 24 characters each. The two phone numbers must be separated by an exclamation point, as in this specification:

    5551212!5551234

The first digit of Dial N# must match a trunk group defined by Ch N Trnk Grp parameter in a Line profile. For example, suppose the first digit of Dial 1#=4-555-1234 is 4. The MAX places the call over the corresponding trunk group.

If the Dial Plan specifies Trunk Grp, the digits following the first digit constitute an ordinary phone number. If the Dial Plan is Extended, the two digits that point to a Dial Plan profile come next, followed by an ordinary phone number.

Dependencies: This parameter is inapplicable unless trunk groups are enabled in the System profile.

Location: `System > Destinations`

See Also: B1 Trnk Grp, B2 Trnk Grp, Ch N Trnk/Grp, Use Trunk Grps, Dial Plan

## Dial Brdcast

Description: Specifies whether the MAX will dial this connection when it receives Ethernet broadcast packets. By default, the MAX does not dial-on-broadcast; it relies on its internal bridging table to bring up specific bridged connections.

If dial-on-broadcast is enabled in one or more Connection profiles, the MAX brings up all of those profiles whenever it receives Ethernet broadcast packets. It never uses a bridging table entry for those connections, even if one exists.

Usage: Specify Yes or No. No is the default.

- Yes means that the MAX dials this connection if it is not online and the MAX receives a frame whose MAC address is set to broadcast.

- No specifies that broadcast packets do not cause the MAX to dial this connection.

Dependencies: This parameter applies only if the Connection profile enables bridging and allows outgoing calls.

Location: `Ethernet > Connections`

See Also: Connection #, Bridge, AnsOrig

## Dial Plan

Description: Specifies whether a module uses trunk groups or the extended dial plan. The extended dial plan is typically used to route calls from a terminating device on a Host BRI line out to the WAN using PRI channels. However, it can also be used to set up the PRI parameters for other outbound calls.

Usage: Specify one of the following values:

- Extended specifies that the MAX uses the extended dial plan.

  When Dial Plan is Extended and the use of trunk groups is enabled in the System profile, the first digit of the Dial # parameter or Dial N# parameter specifies a trunk group; the next two digits specify a Dial Plan profile containing the parameters the MAX uses to make the call. The parameters in the Dial Plan profile constitute the extended dial plan.

  Because the Dial Plan profile parameters apply only to PRI lines, choose Extended only if the MAX makes outgoing calls on PRI lines.

- Trunk Grp specifies that the digits following the first digit constitute an ordinary phone number.

  The first digit specifies a trunk group. If you choose this setting for calls on a T1 PRI line, the Dial Plan profile parameters default to data service set to Inherit, Call-by-Call set to 0, and PRI # Type set to National.

Example: Dial Plan=Trunk Grp

Location: `Ethernet > Mod Config > WAN Options, Host/BRI > Line Config > Line N, Host/ Dual (Host/6) > PortN Menu > Port Config, BRI/LT > Line Config > Line N`

See Also: B1 Trnk Grp, B2 Trnk Grp, Call-by-Call, Ch N Trnk Grp, Data Svc, Dial #, Dial N#, PRI # Type

## Dial Query

Description: Specifies whether the MAX places a call to the location indicated in the Connection profile when a workstation on the local IPX network looks for the nearest IPX server. More than one Connection profile can have this parameter set to Yes. As a a result, several connections can occur at the same time.

Usage: Specify Yes or No. No is the default.

- Yes specifies that the MAX places a call to the location specified in the Connection profile when a workstation looks for the nearest server.

  Note that a workstation is likely to stop attempting to find a server before the MAX establishes any connections with the Dial Query mechanism.

- No specifies that the MAX does not place a call to the location specified in the Connection profile when a workstation looks for the nearest server.

Dependencies: If there is an entry in the MAX unit's routing table for the location specified by the Connection profile, Dial Query has no effect.

Location: `Ethernet > Connections > IPX Options`

## Dialout OK

Description: Specifies whether or not the Connection profile can be used to dial out using one of the MAX unit's digital modems.

Usage: Specify Yes or No. The default is No.

- Yes indicates that the Connection profile allows modem dialout.

- No indicates that the Connection profile does not allow modem dialout.

Example: Dialout OK=Yes

Dependencies: This parameter is not applicable unless Imm. Modem Access is set to User.

Location: `Ethernet > Connections > Telco Options`

See Also: Imm. Modem Access

## Direct Call Addr

Description: For DTE-initiated calls, this specifies the default host's X.121 address.

Usage: Specify an alphanumeric string. You can enter up to 15 characters. The default is null.

Dependencies: This parameter is always applicable.

Location: `Ethernet > Connections > any Connection profile > Encaps options
Ethernet > Answer > T3POS options`

## Disc on Auth Timeout

Description: Specifies whether the MAX gracefully shuts down the PPP connection on a external authentication server timeout.

Usage: Specify Yes or No. No is the default.

- Yes causes the MAX to hang up a PPP connection on RADIUS timeout.

- No causes it to shut down cleanly when RADIUS times out.

Dependencies: This parameter applies only to PPP connections.

Location: `Ethernet > Answer > PPP Options`

See Also: PPP

## DLCI

Description: Specifies a frame relay DLCI number for a gateway or circuit connection. A DLCI is a number between 16 and 991, which is assigned by the frame relay administrator. A DLCI is not an address, but a local label that identifies a logical link between a device and a frame relay switch. The switch uses the DLCI to route frames through the network, and the DLCI may change as frames are passed through multiple switches.

The MAX receives an incoming PPP call, examines the destination address, and brings up the appropriate Connection profile to that destination, as usual. If the Connection profile specifies frame-relay encapsulation, the Frame Relay profile, and a DLCI, the MAX encapsulates the packets in frame relay (RFC 1490) and forwards the data stream out to the frame relay switch using the specified DLCI. The frame relay switch uses the DLCI to route the frames. This is known as gateway mode.

Usage: Specify a number between 16 and 991. The default is 16. Ask your frame relay network administrator for the value you should enter.

Example: DLCI=17

Dependencies: This parameter applies only to FR and FR_CIR encapsulated calls.

Location: `Ethernet > Connections > Encaps Options`

See Also: Encaps, FR Direct, FR DLCI

## DM

Description: Specifies the subaddress associated with the MAX unit's digital modems. The MAX routes an incoming call whose subaddress matches the value of DM to the first available digital modem; the MAX handles such a call as a terminal server call. If the subaddress matches DM, but no digital modem is available, the MAX clears the call.

Usage: Specify a subaddress. You can specify a number between 0 and 99. The default is 0.

Dependencies: This parameter is ignored if the Sub-Adr parameter is not set to Routing.

Location: `System > Sys Config`

See Also: Ans N#, Sub-Adr

## Domain Name

Description: Specifies the local DNS domain name. The domain name is used for DNS lookups. When the MAX is given a hostname to look up, it tries various combinations including appending the configured domain name. The secondary domain name (Sec Domain Name) can specify another domain name that the MAX can search using DNS.

Usage: Specify the domain name of the MAX. You can enter up to 63 characters.

Location: `Ethernet > Mod Config > DNS`

See Also: Pri DNS, Sec DNS, Sec Domain Name

## Download

Description: Enables or disables permission to download the configuration of the MAX using the Save Cfg parameter. Passwords are not saved to file.

Note: Passwords are not saved when you download the configuration. If you upload a saved configuration, all passwords are wiped out.

Usage: Specify Yes or No. No is the default.

- Yes means the operator can download the MAX configuration (without the password values) by using the Save Cfg command in the Sys Diag menu.

- No disables this permission.

Dependencies: This parameter is not applicable if the Operations permission is disabled.

Location: `System > Security`

See Also: Chapter 4, MAX Diag Command Reference.

## DownMetric

Description: This parameter specifies the metric for a route whose associated WAN connection is down.

Usage: Specify an integer. The higher the metric, the less likely that the MAX will use the route. The default metric for online WAN connections is 1. The default metric for offline WAN connections is 7. The metric you specify is in effect only as long as the WAN connection is down.

See Also: DownPreference

## DownPreference

Description: This parameter specifies the preference value for a route whose associated WAN connection is down.

Usage: Specify an integer. A higher preference number represents a less desirable route. The default preference for online WAN connections is 60. The default preference for offline WAN connections is 120. The preference you specify is in effect only as long as the WAN connection is down.

Dependencies: Make sure that routes for offline connections have a higher preference number than routes for online connections. The following table lists the factory default values for route preferences.

Table 3-2. Default route preferences

#### Route type | #### Default value
--- | ---
Interface | 0
ICMP | 30
RIP | 100

## DS0 Min Rst

Description: Specifies when the MAX should reset accumulated DS0 minutes to 0 (zero); you can also use this parameter to specify that the MAX should disable the timer altogether.

A DS0 minute is the online usage of a single 56-kbps or 64-kbps switched channel for one minute. When the usage exceeds the maximum specified by the Max DS0 Mins parameter, the MAX cannot place any more calls, and takes any existing calls offline.

In a System profile, the accumulated minutes apply to all ports on the MAX and to the Ethernet module. In a Port profile, the accumulated minutes apply only to the associated AIM port.

Usage: Specify one of the following values:

- Daily specifies that the MAX resets the accumulated DS0 minutes to 0 (zero) every day at 12 A.M.

- Monthly specifies that the MAX resets the accumulated DS0 minutes to 0 (zero) on the first day of every month at 12 A.M.

- Off (the default) specifies that the MAX disables the Max DS0 Mins parameter in the System profile or Port profile.

## Dst Adrs

Description: Specifies a destination IP address. After this value has been modified by applying the specified Dst Mask, it is compared to a packet's destination address.

Usage: Specify a destination IP address the MAX should use for comparison when filtering a packet. The zero address 0.0.0.0 is the default. If you accept the default, the MAX does not use the destination address as a filtering criterion.

Example: Dst Adrs=10.62.201.56

Dependencies: This parameter applies only to filters of type IP.

Location: `Ethernet > Filters > Input filters > In filter N > IP, Ethernet > Filters > Output filters > Out filter N > IP`

See Also: Dst Mask

## Dst Mask

Description: Specifies a mask to apply to the Dst Adrs before comparing it to the destination address in a packet. You can use it to mask out the host portion of an address, for example, or the host and subnet portion.

The MAX applies the mask to the address using a logical AND after the mask and address are both translated into binary format. The mask hides the portion of the address that appears behind each binary 0 (zero) in the mask. A mask of all zeros (the default) masks all bits, so all destination addresses are matched. A mask of all ones (255.255.255.255) masks no bits, so the full destination address to a single host is matched.

Usage: Specify the mask in dotted decimal format. The zero address 0.0.0.0 is the default; this setting indicates that the MAX masks all bits. To specify a single destination address, set Dst Mask=255.255.255.255 and set Dst Adrs to the IP address that the MAX uses for comparison.

Example: Dst Mask=255.255.255.0

Dependencies: This parameter applies only to filters of type IP.

Location: `Ethernet > Filters > Input filters > In filter N > IP, Ethernet > Filters > Output filters > Out filter N > IP`

See Also: Dst Adrs

## Dst Port #

Description: Specifies a value to compare with the destination port number in a packet. The default setting (zero) indicates that the MAX disregards the destination port in this filter. Port 25 is reserved for SMTP; that socket is dedicated to receiving mail messages. Port 20 is reserved for FTP data messages, port 21 for FTP control sessions, and port 23 for telnet.

Note: The Dst Port Cmp parameter specifies the type of comparison to be made.

Usage: Specify the number of the destination port the MAX should use for comparison when filtering packets. You can enter a number between 0 and 65535. The default setting is 0 (zero), which means the MAX does not compare destination ports

Example: Dst Port #=25

Dependencies: This parameter applies only to filters of type IP.

Location: `Ethernet > Filters > Input filters > In filter N > IP, Ethernet > Filters > Output filters > Out filter N > IP`

See Also: Dst Port Cmp, Src Port Cmp, Src Port #

## Dst Port Cmp

Description: Specifies the type of comparison the MAX makes when using the Dst Port # parameter.

Usage: Specify one of the following values:

- None specifies that the MAX does not compare the packet's destination port to the value specified by Dst Port #.

  None is the default.

- Less specifies that port numbers with a value less than the value specified by Dst Port # match the filter.

- Eql specifies that port numbers equal to the value specified by Dst Port # match the filter.

- Gtr specifies that port numbers with a value greater than the value specified by Dst Port # match the filter.

- Neq specifies that port numbers not equal to the value specified by Dst Port # match the filter.

Dependencies: This parameter works only for TCP and UDP packets. You must set it to None if the Protocol parameter is not set to 6 (TCP) or 17 (UDP).

Location: `Ethernet > Filters > Input filters > In filter N > IP, Ethernet > Filters > Output filters > Out filter N > IP`

Usage: Specify the address. Contact your service provider for the correct address.

Dependencies: This parameter applies only to EU-UI connections.

Location: `Ethernet > Connections > Encaps Options`

See Also: DCE Addr, Encaps

## DTE init. mode

Description: For DTE-initiated calls, this specifies the default data transfer mode. Note that the DTE can override this setting with a opening frame.

Usage: Specify one of the following values:

- Local (the default)

  Specifies that error recovery is performed locally. In this mode, the MAX does not send supervisory frames that is, ACKs and NAKs) across the X.25 network. The T3POS PAD is responsible for sending supervisor frames to the T3POS DTE.

- Transparent

  Specifies that the T3POS PAD does not provide any error recovery. In this mode, the DTE and the host system provide error recovery for the connection. In Transparent mode, however, the T3POS PAD does recognize a clear request command signal from the DTE (that is, DLE, EOT) and clears the call when it receives a DLE, EOT command.

- Blind

  The same as Transparent mode except that the T3POS PAD does not clear a call when it receives a clear request command from the DTE. In this mode, the PAD or the host system must clear the call. The PAD passes all data blindly, without regard to the protocol in use. This mode provides a means to pass raw binary data between the DTE and the host system without reference to the protocol being used.

- Bin-Local

  Specifies that there is no error recovery between the T3POS PAD and the host but that there is error recovery between the PAD and the DTE. Like Blind mode, it passes data between the DTE and the host without reference to the protocol being used., but continues to use the T3POS protocol between the DTE and the PAD.

Dependencies: This parameter is always applicable.

Location: `Ethernet > Connections > any Connection profile > Encaps options
Ethernet > Answer > T3POS options`

## DTE N392

Description: Specifies the number of errors during DTE N393 monitored events which cause the user side to declare the network side procedures inactive.

Dependencies: This parameter is N/A when FR Type is DCE.

Location: `Ethernet > Frame Relay`

## DTE N393

Description: Specifies the DTE monitored event count (between 1 and 10). It is N/A when FR Type is DCE.

Usage: Specify a value between 1 and 10 that is greater than DTE N392.

Example: DTE N393=5

Dependencies: This parameter is N/A when FR Type is DCE.

Location: `Ethernet > Frame Relay`

## Dual Ports

Description: Specifies whether the AIM ports in a module or in the base system are paired for dual-port calls. If you are configuring the interface to an older model codec that does not support AIM, you can use the pair two AIM ports to provide double the bandwidth for the videoconferencing call. A dual-port call requires that the codec has a dual-port interface.

In a dual-port call, the codec performs its own inverse multiplexing on two channels so that a call can achieve twice the bandwidth of a single channel. A pair of AIM ports on the MAX connects to the codec. The pair includes a primary and secondary port. Because the MAX places the two calls in tandem and clears the calls in tandem, it considers them a single call.

Creating a dual-port configuration does not prevent you from dialing any other type of call from the primary host port of the pair, or from using either port for receiving any call type. Pairing ports does not disable RS-366 dialing at the secondary port.

Usage: Specify one of the following values:

- No Dual (the default) specifies that no host ports are paired for dialing or receiving dual-port calls.

- 1&2 Dual specifies that host ports 1 and 2 are paired for dialing and receiving dual-port calls.

Example: Dual Port=No Dual

Location: `Host/Dual (Host/6) > Mod Config`

## Dyn Alg

Description: Specifies an algorithm for calculating average line utilization (ALU) over a certain number of seconds (Sec History).

Usage: Specify one of the following values:

- Quadratic (the default) gives more weight to recent samples of bandwidth usage than to older samples taken over the specified number of seconds. The weighting grows at a quadratic rate.

- Linear gives more weight to recent samples of bandwidth usage than to older samples taken over the specified number of seconds. The weighting grows at a linear rate.

- Constant gives equal weight to all samples taken over the specified number of seconds.

## E

## Early CD

Description: Specifies when the MAX raises CD (Carrier Detect) at its AIM port. An AIM port uses pins for controlling the data flow through the port. A device sends a signal through a pin and over the line to another device; the signal being sent determines the control-line state. When a device receives a signal indicating that a sender has data to transmit, it raises CD. The process of sending synchronization signals between devices is called handshaking.

Usage: Specify one of the following values:

- None (the default) specifies that the MAX raises CD after the completion of handshaking and an additional short delay.

- Answer specifies that the MAX raises CD (Carrier Detect) as soon as it answers a call, rather than waiting for the completion of handshaking. Choose Answer if your codec times out while waiting for CD.

- Originate specifies that the MAX raises CD as soon as the remote end answers a call, rather than waiting for the completion of handshaking.

- Both specifies that the MAX raises CD without waiting for the completion of handshaking whether it is answering or originating a call.

Example: Early CD=None

Location: `Host/Dual (Host/6) > PortN Menu > Port Config`

## Edit

Description: Enables you to customize which status windows are displayed in the vt100 interface at system startup. If you are running the simplified menus, it determines which AIM port the MAX displays. If you enter a null value when running the simplified menus, the MAX displays host port #1.

Usage: Specify a slot and port address using the format XY-NNN.

- X is the slot number

  The system itself is assigned slot number 0 (00-000).

  The built-in T1 or E1 lines are slot 1 and slot 2 (10-000 and 20-000).

  The six expansion slots are slots 3 through 8 (30-000 through 80-000).

  The Ethernet is slot 9 (90-000).

  EtherData is slot A (A0-000), which is not applicable for units with built-in Ethernet.

  The serial WAN port is slot B (B0-000).

- Y is the port number.

  Zero means any port on the slot.

- The three digits after the dash are the root number.

  A root number of 000 identifies a top-level branch of the menu tree. If N is not zero, the root number identifies a submenu.

Example: Edit=00-000

Location: `System > Sys Config`

Dependencies: This parameter does not apply if the Operations permission is disabled.

Location: `System > Security`

## Enable ASBR

Description: Specifies whether the MAX performs ASBR calculations. ASBRs (autonomous system border routers) perform calculations related to external routes. The MAX imports external routes from RIP-for example, when it establishes a WAN link with a caller that does not support OSPF-and the ASBR calculations are always performed. If you must prevent the MAX from performing ASBR calculations, you can disable the calculations by setting this parameter.

Usage: Specify Yes or No. Yes is the default and should be used for most installations.

- Yes means the MAX performs normal operations related to external routes.

- No means the MAX does not perform the standard ASBR calculations.

Example: Enable ASBR=Yes

Dependencies: This parameter does not apply unless OSPF is in use.

Location: `Ethernet > Mod Config > OSPF global options`

## Enabled

Dependencies: This parameter applies only to X.25/IP connections.

Location: `Ethernet > Connections > Encaps Options`

See Also: Encaps

## Encoding

Description: Specifies the type of T1 PRI line encoding that the MAX uses. Your carrier can tell you which type of encoding you require.

Usage: Specify one of the following values:

- AMI (the default) specifies that the MAX uses Alternate Mark Inversion encoding.

- None is identical to AMI, but without density enforcement.

- B8ZS specifies that the encoding is Bipolar with 8-Zero Substitution. This is often required for ISDN lines.

Example: Encoding=AMI

Dependencies: This parameter applies only to T1 lines.

Location: `Net/T1 > Line Config > Line N`

## Enet Adrs

Description: In a Bridge profile, specifies the physical Ethernet address (MAC address) of a device at the remote end of the link. The Bridge profile correlates a remote MAC address with a Connection profile number, enabling the MAX to bring up that Connection when it receives packets destined for the remote device.

Usage: Specify the physical address of the device on the remote network. An Ethernet address is a 12-digit hexadecimal number. The default setting is 000000000000.

Example: Enet Adrs=0180C2000000

Location: `Ethernet > Bridge Adrs`

See Also: Net Adrs

## ENQ handling

Description: Specifies whether the PAD should expect to receive an ENQ from the host when an X.25 virtual call is established. ENQ indicates that the host is ready to receive data.

Usage: Specify one of the following values:

- Off (the default)

  Specifies that the PAD does not expect to receive an ENQ before sending data to the host. The host is ready to receive data as soon as the X25 call is established.

- On

  Specifies that the PAD does not forward data it receives from the DTE to the host until it either receives an ENQ or the T3 POS timer expires. Note that the PAD does not forward the ENQ to the DTE.

Dependencies: This parameter is always applicable.

Location: `Ethernet > Connections > any Connection profile > Encaps options
Ethernet > Answer > T3POS options`

## EOC Address

Description: Specifies the Embedded Operations Channel (EOC) address from which the MAX rollbacks the signal.

Usage: Specify one of the following values:

- 0 (the default) specifies the remote ISDN TA device

- 1-6 specifies the number of an ISDN repeater between the MAX and the remote TA. 1 specifies the repeater nearest the MAX.

- 7 specifies that the EOC command should be broadcast to all the nodes on the IDSL connection.

Note: The EOC address setting reverts to its default value of 0 whenever you exit the Line Diag submenu.

Location: `BRI/LT > Line Diag > line n`

## EU-RAW

Description: Specifies whether the MAX accepts EU-RAW calls, provided that they meet all other X.75 criteria.

Usage: Specify Yes or No. Yes is the default.

- Yes means the MAX accepts EU-RAW encapsulated calls, provided that they meet all other connection criteria.

- No means the MAX will not accept inbound EU-RAW calls.

Location: `Ethernet > Answer > Encaps

`

## EU-UI

Description: Specifies whether the MAX accepts EU-UI calls, provided that they meet all other X.75 criteria.

- Yes means the MAX accepts EU-UI encapsulated calls, provided that they meet all other connection criteria.

- No means the MAX will not accept inbound EU-UI calls.

Location: `Ethernet > Answer > Encaps

`

## Excl Routing

Description: Enables or disables exclusive port routing. Exclusive port routing is a way to prevent the MAX from accepting calls for which it has no explicit routing destination. If Excl Routing is disabled (the default), the call is routed to a digital modem if the bearer service is voice. If the service is V.110, it is routed to the first available V.110 module. If the service is data, it is routed to the first available AIM port; or if no AIM ports are available, it is routed to the MAX unit's bridge/router. To prevent this service-based routing and instead reject the call, turn Excl Routing on.

Usage: Specify Yes or No. No is the default.

- Yes means the MAX drops calls for which it has no explicit call-routing information (such as Answer numbers, ISDN subaddressing, and so forth).

- No means the MAX uses service-based routing to route voice calls to a digital modem and data calls to an AIM port or its bridge/router software.

Example: Excl Routing=No

Location: `System > Sys Config`

## Exp Callback

Description: Specifies whether the MAX expects outgoing calls to result in a call back from the far-end device. Use this parameter when the remote device requires callback security.

Usage: Specify Yes or No. No is the default.

- Yes means the MAX expects the connection to terminate and result in a call-back from the far-end device. This prevents problems that arise when CLID is set to Required on the device that is expected to callback. If a call fails for any reason, regardless of whether or not the called machine requires CLID and is attempting a callback, the call initiator will still have to wait 90 seconds before attempting the call the same number again if Exp Callback is set to Yes.

- No means the MAX does not expect call-back for this connection.

Example: Exp Callback=No

Location: `Ethernet > Connections > Telco Options`

See Also: Callback

## F

## Fail Action

Description: Specifies the action that the MAX takes when it cannot establish the base channels of a codec connection.

Usage: Specify one of the following values:

- Disc specifies that the MAX clears the call entirely.

- Reduce (the default) specifies that the MAX reduces the bandwidth allocated for the call, and then tries to establish the call with a number of channels lower than the amount specified by Base Ch Count.

  Reduce is the default.

- Retry specifies that the call remains online with the bandwidth available while the MAX attempts to add channels to bring the count up to the value specified by Base Ch Count.

  Retry attempts continue for approximately 30 seconds, until the MAX achieves full bandwidth, or until you reduce the setting of the Base Ch Count parameter. If the MAX cannot make the channel count match the setting of Base Ch Count within 30 seconds, the call remains online.

Example: Fail Action=Retry

Location: `Host/Dual (Host/6) > PortN Menu > Directory`

## FDL

Description: Specifies the FDL (Facilities Data Link) protocol that the MAX uses. FDL is a protocol used by the telephone company to monitor the quality and performance of T1 lines. It provides information at regular intervals to your carrier's maintenance devices.

You continue to accumulate D4 and ESF performance statistics in the FDL Stats windows, even if you do not choose an FDL protocol. Your carrier can tell you which FDL protocol to specify.

Usage: Specify one of the following values:

- None (the default) disables FDL signaling.

- AT&T specifies AT&T FDL signaling.

- ANSI specifies ANSI FDL signaling.

- Sprint specifies Sprint FDL signaling.

Dependencies: This parameter does not apply to D4-framed T1 lines.

Location: `Net/T1 > Line Config > Line N`

See Also: Framing Mode

## Field Service

Description: Enables or disables permission to perform Ascend-provided field service operations, such as uploading new system software. Field service operations are special diagnostic routines not available through MAX menus.

Usage: Specify Yes or No. Yes is the default.

- Yes means the operator can upgrade the system software and perform other field service operations.

- No disables this permission.

Example: Field Service=No

Dependencies: This parameter is not applicable if the Operations permission is disabled.

Location: `System > Security`

## Filter

Description: Specifies the number of a data filter that plugs into the Ethernet profile. The data filter manages data flow on the Ethernet interface. The filter examines each incoming or outgoing packet, and uses the Forward parameter to determine whether to forward or discard it.

Usage: Specify a number between 0 and 199. The number you enter depends on the whether you are applying a filter you created using the vt100 interface, or a firewall you created using Secure Access Manager (SAM).

If you are applying a filter created using the vt100 interface, enter the last 2 digits of the filter number as it appears in the Filters menu.

If you are applying a firewall created with SAM, add 100 to the last 2 digits of the firewall number as it appears in the Firewalls menu. For example, if the number of your firewall is 90-601, specify 101. Refer to your SAM documentation for infomation on downloading firewalls to the MAX. The numbering scheme for filters and firewalls is:

- 0 indicates that no filtering is being used (this is the default)

- 1-99 indicates that a filter created using the vt100 interface is being used

- 100-199 indicates that a filter created using SAM is being used.

When you set Filter to 0 (zero), the MAX forwards all data packets.

Example: Filter=7

Location: `Ethernet > Mod Config > Ether Options`

See Also: Call Filter, Data Filter

## Filter Persistence

Description: Specifies whether the filter or firewall assigned to a Connection profile should persist after the call has been disconnected.

Before Secure Access was supported, the MAX simply constructed a filter on a WAN interface when the connection was established and destroyed the filter when the connection was brought down, even if the connection just timed out momentarily. This works fine for static packet filters, but does not accommodate Secure Access firewalls. Filter Persistence is needed to allow firewalls to persist across connection state changes, but it is not needed for filters. If you do set it for a static packet filter, the filter persists across connection state changes. See the MAX Security Supplement for details.

Note: Firewalls must have persistence to work correctly, but filters do not.

Usage: Specify Yes or No. No is the default.

- Yes causes the filter or firewall to persist across connection state changes. This is not required for a data or call filter, but it is required for firewalls.

- No causes the filter or firewall to be torn down when a connection is brought down.

Example: Filter Persistence=Yes

## Finger

Description: Enables or disables the Finger remote user information protocol (RFC 1288). Finger returns information about users currently logged into the MAX. Note that for security reasons the MAX does not forward Finger requests.

Usage: Specify one of the following values:

- Yes enables the MAX to respond to Finger requests.

- No disables the Finger protocol on the MAX.

Location: `Ethernet > Mod Config

`

## Flag Idle

Description: Specifies whether a dynamic call to an AIM port looks for a flag pattern (01111110) or a mark pattern (11111111) as the idle indicator.

Usage: Specify Yes or No. Yes is the default.

- Yes means the MAX uses a flag pattern (01111110) as the idle indicator on an AIM dynamic call.

- No means it uses a mark pattern (11111111) as the idle indicator on an AIM dynamic call.

Example: Flag Idle=Yes

Location: `Host/Dual (Host/6) > PortN Menu > Directory`

## Force56

Description: Specifies whether the MAX uses only the 56-kbps portion of a channel, even when all 64 kbps appear to be available.

Use this feature when you place calls to European or Pacific Rim countries from within North America and the complete path cannot distinguish between the Switched-56 and Switched-64 data services. This feature is not required if you are placing calls only within North America.

Usage: Specify Yes or No. No is the default.

- Yes means the MAX uses 56K of a channel that may provide up to 64K bandwidth.

- No means the MAX uses the full 64K bandwidth if it is available.

Dependencies: This parameter should not be enabled for calls within North America.

Example: Force56=No

Location: `Host/Dual (Host/6) > PortN Menu > Directory, Ethernet > Connections > Telco Options, Ethernet > Answer`

## Forward

Description: Specifies whether the MAX discards or forwards packets that match the filter specification. When no filters are in use, the MAX forwards all packets by default. When a filter is in use, the default is to discard matching packets (Forward=No).

Usage: Specify Yes or No. No is the default.

- Yes means the MAX forwards packets that match the filter.

- No means the MAX discards packets that match the filter.

Example: Forward=No

Location: `Ethernet > Filters > Input filters > In filter N > IP, Ethernet > Filters > Output filters > Out filter N > IP`

See Also: Call Filter, Data Filter, Filter, More

## Forwarding

Description: Enables multicast forwarding in the MAX.

Note: When you change the Forwarding parameter from No to Yes, the multicast subsystem reads the values in the Ethernet profile and initiates the forwarding function. If you modify a multicast value in the Ethernet profile, you must set this parameter to No and then set it to Yes again to force a read of the new value.

Usage: Specify Yes or No. No is the default.

- Yes turns on multicast forwarding in the MAX.

- No disables multicast forwarding.

Example: Forwarding=Yes

Location: `Ethernet > Mod Config > Multicast`

See Also: Mbone profile, Multicast Client

## FR

Description: Specifies whether the MAX accepts incoming frame relay-encapsulated calls.

Usage: Specify Yes or No. Yes is the default.

- Yes means the MAX accepts calls that use frame relay encapsulation, provided that they meet all other connection criteria.

- No means the MAX will not accept inbound calls using frame relay encapsulation.

Location: `Ethernet > Answer > Encaps

` See Also: Encaps, FR Prof, DLCI

## FR Direct

Description: Specifies whether the MAX redirects incoming packets to the frame relay switch without processing. A redirect connection is a dial-in IP routing connection (typically using PPP), for which the MAX simply forwards the packets automatically to the frame-relay switch without examining destination addresses or its routing table. In effect, the MAX passes on the responsibility of routing those packets to a later hop on the frame relay network. This is known as redirect mode, and is not commonly used.

Note: A frame relay redirect connection is not a full-duplex tunnel between the PPP dial-in and the switch. The IP packets coming back from the frame relay switch are handled by the MAX router software, so they must contain the PPP caller's IP address to be routed correctly back across the WAN.

Usage: Specify Yes or No. No is the default.

- Yes means this connection is a frame relay redirect connection.

- No means this is not a redirect connection.

Example: FR Direct=No

Dependencies: This parameter is not applicable for FR or FR_CIR encapsulated calls.

Location: `Ethernet > Connections > Session Options`

See Also: FR DLCI, FR Prof

## FR DLCI

Description: Specifies a frame relay DLCI number to be used for redirect connections. A redirect connection is a dial-in IP routing connection (typically using PPP), for which the MAX simply forwards the packets automatically to the frame-relay switch without examining destination addresses or its routing table. In effect, the MAX passes on the responsibility of routing those packets to a later hop on the frame relay network. This is known as redirect mode, and is not commonly used.

Note: More than one redirected PPP connection can share a frame relay DLCI.

Usage: Specify the DLCI obtained from the frame relay administrator for redirect links.

Example: FR DLCI=72

Dependencies: This parameter is not applicable if frame relay encapsulation is in use.

Location: `Ethernet > Connections > Session Options`

See Also: FR Direct

## FR Prof

Description: Specifies the name of the Frame Relay profile to use for forwarding this link on the frame relay network.

Usage: Specify the name of a configured Frame Relay profile. This is the string assigned in the Name parameter of the Frame Relay profile, specified exactly including case changes.

Example: FR Prof=pacbell

Location: `Ethernet > Connections > Encaps Options, Ethernet > Connections > Session Options`

See Also: FR Type, DLCI

## FR Type

Description: Specifies the type of interface between the MAX and a frame relay switch or CPE (customer premises equipment) on the frame relay network.

Note: For NNI or UNI-DTE connections, the MAX is able to query the device at the other end of the link about the status of the DLCIs in the connection. If any of the DLCIs become unusable and the DLCIs Connection profile has a specified Backup connection, the MAX dials the Connection profile specified in the Backup parameter in the Session Options submenu.

Usage: Specify one of the following values:

- NNI (Network to network interface)

  An NNI interface connection allows the MAX to appear as a frame relay network interface based on the NNI specifications. It performs both DTE and DCE link management, and allows two separate frame relay networks to connect via a common protocol.

- UNI-DCE (User to network interface-data communications equipment)

  UNI is the interface between an end-user and a network end point (a router or a switch) on the frame relay network. In a UNI-DCE connection, the MAX operates as a frame relay router communicating with a DTE device (customer premises equipment). To the DTE devices, it appears as a frame relay network end point.

- UNI-DTE (User to network interface-data terminal equipment)

  In a UNI-DTE connection, the MAX is configured as a UNI-DTE communicating with a frame relay switch. It acts as a frame relay feeder and performs the DTE functions specified for link management.

Example: FR Type=NNI

Location: `Ethernet > Frame Relay`

## Framed Only

Description: Specifies whether the user is allowed access to all the terminal server commands or to a subset of them.

Usage: Specify one of the following values:

- No (the default)

  Specifies that terminal server users connecting through this profile have unlimited access to the terminal server commands.

- Yes

  Specifies that terminal server users connecting through this profile only have access to the PPP, SLIP, CSLIP, and Quit terminal server commands.

Dependencies: Keep this additional information in mind:

- Framed Only has no affect if TS Enabled is set to No in the Ethernet > Mod Config > TServ Options submenu.

- PPP, SLIP, and CSLIP must be enabled in the Ethernet > Mod Config > TServ Options submenu before users can start a PPP, SLIP, or CSLIP session.

Location: `Ethernet > Answer > Session Options
Ethernet > Connections > any Connection profile > Session Options

`

## Frame Length

Description: Specifies the maximum number of bytes allowed in the information field by V.120 or X.75 terminal adapters that call the MAX.

Usage: For a V.120 TA, specify a number between 30 to 260. The default is 256. For an X.75 TA, specify a number between 128 and 2048. The default value is 2048.

Example: Frame Length=256

Location: `Ethernet > Answer > V.120 Options, Ethernet > Answer > X.75 Options`

See Also: K Window Size, N2 Retransmission Count, T1 Retransmission Timer, X.75

## Framed Addr Start

Description: This parameter specifies whether the Ascend unit sends a second accounting Start record to the RADIUS server when the Framed-Address and Framed-Protocol attributes are assigned to a user transferring to a framed protocol (such as PPP or SLIP).

Usage: You can specify one of these settings:

- Yes indicates that the Ascend unit sends a second accounting Start record.

- No indicates that the Ascend unit does not send a second accounting Start record.

  No is the default.

Location: `Ethernet profile: Ethernet > Mod Config > Auth

`

## Framing Mode

Description: Specifies the framing mode the T1 or E1 physical layer uses. Your carrier can tell you which framing mode to choose.

Note: If the MAX has internal bantam test jacks, it can support a different framing mode for each line in a Drop-and-Insert application. If you set the second line to drop-and-insert and use Inband signaling, you can set Framing Mode to ESF on one line and D4 on the other.

Usage: Specify one of the following values for a Net/T1 line:

- D4 specifies the D4 format, also known as the Superframe format.

  This format consists of 12 consecutive frames, separated by framing bits. Do not use this setting with ISDN D-channel signaling; false framing and Yellow Alarm emulation can result.

- ESF specifies the Extended Superframe Format.

  This format consists of 24 consecutive frames, separated by framing bits. The ISDN specification advises that you use ESF with ISDN D-channel signaling.

For a Net/E1 line, specify one of the following values:

- G.703 (the default) specifies the standard framing mode used by most E1 ISDN providers and by DASS 2.

- 2DS specifies a variant of G.703 required by most E1 DPNSS providers in the U.K.

Location: `Net/T1 > Line Config > Line N, Net/E1 > Line Config > Line N

`

## FT1 Caller

Description: Specifies whether the MAX initiates an FT1-AIM, FT1-B&O, or Nailed/MPP call, or whether it waits for the remote end to initiate these types of calls. If the remote end has FT1 Caller set to No, set it to Yes on the local MAX; by the same token, if the remote end has FT1 Caller set to Yes, set it to No on the local MAX.

Usage: Specify Yes or No. No is the default.

- Yes means the MAX can initiate FT1-AIM, FT1-B&O, or Nailed/MPP calls using this profile.

- No means the MAX cannot initiate these calls. No implies that the other end of the connection will always initiate the call.

Dependencies: This parameter applies only when the call type is FT1-AIM or FT1-B&O (in a Port profile) or Nailed/MPP (in a Connection profile). It should be set to Yes at only one side of the connection.

Location: `Host/Dual (Host/6) > PortN Menu > Directory, Ethernet > Connections > Telco Options`

See Also: Call Type

## G

## Gateway

Description: Specifies the IP address of the next-hop router that a packet must go through to reach the route's destination address. A next-hop router is either directly connected (on Ethernet) or is one hop away on a WAN link.

Usage: Specify the IP address of the next-hop router.

Example: Gateway=200.207.23.1

Dependencies: This parameter does not apply if the MAX does not support IP routing.

Location: `Ethernet > Static Rtes`

See Also: Dest

## GK IP Adrs

Description: Specifies the IP address of the MultiVoice Access Manager. When the MAX, acting as a MultiVoice Gateway, receives voice calls, the MultiVoice Access Manager directs the MultiVoice Gateway how to route the call to a destination MultiVoice Gateway.

Usage: Specify the IP address of the MultiVoice Access Manager.

Example: GK IP Adrs=10.10.10.1/24

Dependencies: GK IP Adrs does not apply if the MAX does not support IP routing or does not act as a MultiVoice Gateway.

Location: `Ethernet > Mod Config > VOIP Options`

See Also: VPN Mode, Pkt Audio Mode

## Group

Description: Assigns a group of nailed channels to a connection. For connections whose call type is Nailed/MPP, you can concatenate group numbers by separating them with a comma; for example, Group=1,3,5,7 assigns four groups of nailed channels.

Note: Nailed channels are used for permanent connections, which are typically leased. It is important to keep those channels dedicated to the connection. Do not assign the same group number to more than one profile of any type.

Usage: Specify the group number assigned to nailed channels in a Line profile.

Example: Group=3

Location: `Host/Dual (Host/6) > PortN Menu > Directory, Ethernet > Connections > Telco Options`

See Also: Call Type, Ch N Prt/Grp, Ch N

## H

## Handle IPX

Description: Specifies IPX server or IPX client bridging.

Note: If NetWare servers are supported on both sides of the WAN connection, we strongly recommend that you use an IPX routing configuration instead of bridging IPX. If you bridge IPX in that type of environment, client-server logins will be lost when the MAX brings down an inactive WAN connection.

Usage: Specify one of the following values:

- None (the default) disables IPX server or IPX client bridging.

- Client (for IPX client bridging). IPX client bridging is used when the local Ethernet supports NetWare clients but no servers. In an IPX client bridging configuration, you want the local clients to be able to bring up the WAN connection by querying (broadcasting) for a NetWare server on a remote network. You also want to filter IPX RIP and SAP updates, so the connections do not remain up permanently.

- Server (for IPX server bridging). IPX server bridging is used when the local Ethernet supports NetWare servers (or a combination of clients and servers) and the remote network supports NetWare clients only.

Example: Handle IPX=Client

Dependencies: This parameter does not apply if IPX routing is enabled for this connection.

Location: `Ethernet > Connections > IPX Options`

See Also: Dial Brdcast, NetWare t/o

## Handle IPX Type 20

Description: Specifies whether the MAX will propagate IPX type 20 packets over all its interfaces. Some applications (like NETBIOS) use IPX Type 20 packets to broadcast names over a network. By default, these broadcasts are not propagated over routed links, since Novell recommends not forwarding these packets over links that have less than 1 Mbps throughput. However, some applications, like NetBIOS over IPX, require these packets in order to work.

Usage: Specify Yes or No. No is the default.

- Yes enables the MAX to propagate IPX type-20 packets.

- No means these broadcasts are not propagated.

Dependencies: This parameter does not apply if the MAX does not support IPX routing.

Location: `Ethernet > Mod Config > Ether options`

## HeartBeat Addr

Description: Specifies a multicast address. The MAX listens for packets to and from this group to perform the heartbeat-monitoring feature. When it is running as a multicast forwarder, the MAX is continually receiving multicast traffic. The heartbeat-monitoring feature enables the administrator to monitor possible connectivity problems by continuously polling for this traffic and generating an SNMP alarm trap if there is a traffic breakdown.

Note: Heartbeat monitoring is optional. It is not required for multicast forwarding.

Usage: Specify a multicast address to use for heartbeat monitoring.

Example: HeartBeat Addr=224.1.1.1

Dependencies: To set up heartbeat monitoring, you must configure several parameters that define what packets will be monitored, how often and for how long to poll for multicast packets, and the threshold for generating an alarm. These parameters do not apply if multicast forwarding is not in use.

Location: `Ethernet > Mod Config > Multicast`

See Also: HeartBeat Udp Port, Source Addr, Source Mask, HeartBeat Slot Time, HeartBeat Slot Count, Alarm Threshold

## HeartBeat Udp Port

Description: Specifies a UDP port number. The MAX listens only to packets received on that port to perform the heartbeat-monitoring feature. When it is running as a multicast forwarder, the MAX is continually receiving multicast traffic. The heartbeat-monitoring feature enables the administrator to monitor possible connectivity problems by continuously polling for this traffic and generating an SNMP alarm trap if there is a traffic breakdown.

Note: Heartbeat monitoring is optional. It is not required for multicast forwarding.

Usage: Specify a UDP port to use for heartbeat monitoring.

Example: HeartBeat Udp Port=16387

Dependencies: To set up heartbeat monitoring, you must configure several parameters that define what packets will be monitored, how often and for how long to poll for multicast packets, and the threshold for generating an alarm. These parameters do not apply if multicast forwarding is not in use.

Location: `Ethernet > Mod Config > Multicast`

See Also: HeartBeat Addr, Source Addr, Source Mask, HeartBeat Slot Time, HeartBeat Slot Count, Alarm Threshold

## HeartBeat Slot Count

Description: Specifies how many times to poll for multicast traffic before comparing the number of heartbeat packets received to the Alarm Threshold. The MAX polls for multicast traffic the specified number of times, waits for the interval specified in the HeartBeat Slot Time parameter, and then polls again.

Note: Heartbeat monitoring is optional. It is not required for multicast forwarding.

Usage: Specify a number of seconds.

Example: HeartBeat Slot Count=10

Dependencies: To set up heartbeat monitoring, you must configure several parameters that define what packets will be monitored, how often and for how long to poll for multicast packets, and the threshold for generating an alarm. These parameters do not apply if multicast forwarding is not in use.

Location: `Ethernet > Mod Config > Multicast`

See Also: HeartBeat Addr, Heartbeat Udp Port, Source Addr, Source Mask, HeartBeat Slot Time, Alarm Threshold

## HeartBeat Slot Time

Description: Specifies how often (in seconds) the MAX should poll for multicast traffic. The MAX polls for multicast traffic, waits for this interval, and then polls again.

Note: Heartbeat monitoring is optional. It is not required for multicast forwarding.

Usage: Specify a number of seconds.

Example: HeartBeat Slot Time=10

Dependencies: To set up heartbeat monitoring, you must configure several parameters that define what packets will be monitored, how often and for how long to poll for multicast packets, and the threshold for generating an alarm. These parameters do not apply if multicast forwarding is not in use.

Location: `Ethernet > Mod Config > Multicast`

See Also: HeartBeat Addr, Heartbeat Udp Port, Source Addr, Source Mask, HeartBeat Slot Count, Alarm Threshold

## HelloInterval

Description: Specifies the number of seconds between sending OSPF Hello packets on the interface. OSPF routers use Hello packets to recognize when a router is down.

Usage: Specify a number. In a Connection profile, the default is 40 seconds. In the Ethernet profile, the default is 10 seconds.

Example: HelloInterval=60

Location: `Ethernet > Connections > OSPF Options, Ethernet > Mod Config > OSPF Options`

See Also: DeadInterval

## High BER

Description: Specifies the maximum bit-error rate for any PRI line. The bit-error rate consists of the number of bit errors that occur per second. The number that comes after the double asterisks specifies the power of 10 for the current ratio of error bits to total bits.

Usage: Specify one of the following values:

- 10**-3 (the default)

- 10**-4

- 10**-5

Location: `System > Sys Config

` See Also: High BER Alarm

## High BER Alarm

Description: Specifies whether the back panel alarm relay closes when the bit-error rate exceeds the value specified by the High BER parameter.

The MAX has an alarm relay whose contacts remain open on the back panel's alarm relay terminal block during normal operation. If you enable them, the alarm relay contacts close during loss of power, hardware failure, or a system reset. The High BER Alarm parameter specifies whether the contacts also close when the bit-error rate exceeds the High BER parameter value.

Usage: Specify Yes or No. No is the default.

- Yes causes the MAX to close the back panel alarm relay when the bit-error rate exceeds the High BER value.

- No causes the MAX to log the event but not close the alarm relay.

Location: `System > Sys Config

` See Also: High BER

## Hop Count

Description: Specifies the number of hops to the destination IPX network. From the MAX, the local IPX network is one hop away. The IPX network at the remote end of the route is two hops away-one hop across the WAN and one hop to the local IPX network.

Usage: Specify a valid hop count from 1 to 15. A hop count of 16 is considered unreachable and is not valid for static routes.

Dependencies: This parameter does not apply if the MAX does not support IPX routing.

Location: `Ethernet > IPX Routes`

See Also: Route IPX

## Host init. mode

Description: For host-initiated calls, this specifies the default data transfer mode. Note that the host can override this setting with a control frame.

Usage: Specify one of the following values:

- Local (the default)

  Specifies that error recovery is performed locally. In this mode, the MAX does not send supervisory frames that is, ACKs and NAKs) across the X.25 network. The T3POS PAD is responsible for sending supervisor frames to the T3POS DTE.

- Transparent

  Specifies that the T3POS PAD does not provide any error recovery. In this mode, the DTE and the host system provide error recovery for the connection. In Transparent mode, however, the T3POS PAD does recognize a clear request command signal from the DTE (that is, DLE, EOT) and clears the call when it receives a DLE, EOT command.

- Blind

  The same as Transparent mode except that the T3POS PAD does not clear a call when it receives a clear request command from the DTE. In this mode, the PAD or the host system must clear the call. The PAD passes all data blindly, without regard to the protocol in use. This mode provides a means to pass raw binary data between the DTE and the host system without reference to the protocol being used.

- Bin-Local

  Specifies that there is no error recovery between the T3POS PAD and the host but that there is error recovery between the PAD and the DTE. Like Blind mode, it passes data between the DTE and the host without reference to the protocol being used., but continues to use the T3POS protocol between the DTE and the PAD.

Dependencies: This parameter is always applicable.

Location: `Ethernet > Connections > any Connection profile > Encaps options,
Ethernet > Answer > T3POS options`

## Host #N Addr (N=1-4)

Description: Specifies the IP address of the first, second, third, and fourth hosts listed in the terminal server menu-mode interface. These are the only hosts to which terminal server users can Telnet or Rlogin to if they are not allowed to enter command mode. Note that you can specify a longer list of hosts using RADIUS.

To specify hosts to which terminal-server users establish raw TCP sessions, enter the identifier rawTcp before the host address (or DNS name).

Usage: Specify the IP address of the host. The default value is 0.0.0.0/0.

    To specify that the MAX establish raw TCP sessions instead of Telnet or Rlogin, configure
    Host #N Addr using the following format:

    rawTcp hostaddress portnumber

where:

- `hostaddress` indicates the IP address (or DNS name) of a raw TCP host.

- `portnumber` is the UDP port used for raw TCP sessions.

Example: Host # Addr=10.207.23.6/24

Dependencies: This parameter is ignored if Remote Conf=Yes. It is not applicable if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: Remote Conf

## Host #N Text (N=1-4)

Description: Specifies a text description of the first, second, third, and fourth hosts listed in the terminal server menu-mode interface.

Usage: Specify a text description of the host.

Example: Host # Text=Database Server

Dependencies: This parameter is ignored if Remote Conf=Yes. It is not applicable if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: Remote Conf

## Hunt-n (N=1-3)

Description: These parameters indicate the hunt group numbers associated with the T1 line in a specific Line Profile. An SNMP manager can retrieve these numbers from Ascend devices and store them in a table that includes the devices from which information is retrieved and the hunt group numbers in their WAN Line Profiles.

Usage: Enter the phone number for the hunt group associated with current line in the Hunt-x # parameter.

Example: Hunt-1 #=847-4747

Dependencies: The numbers entered in the Hunt-n # parameters must be the same as the numbers that are assigned to T1 channels, creating the hunt group

Location: `Net T1 Line Profile > Line Config`

## I

## ICMP Redirects

Description: Specifies whether the MAX accepts or ignores Internet ICMP Redirect packets. ICMP was designed to dynamically find the most efficient IP route to a destination. ICMP redirect packets are one of the oldest route discovery methods on the Internet and one of the least secure, because it is possible to counterfeit ICMP redirects and change the way a device routes packets.

Usage: Specify one of the following values:

- Accept (to process ICMP redirects). This is the default.

- Ignore (to drop ICMP redirects)

Location: `Ethernet > Mod Config

`

## Id Auth

Description: Specifies how CLID (calling line ID) or DNIS (Dial Number Information Service) should be used for authentication.

Usage: Specify one of the following values:

- Ignore (the default)

  Don't require a matching ID from incoming calls.

- Prefer

  Authenticate using the CLID if available, otherwise fall back to using PAP or CHAP authentication.

- Require

  The CLID must be valid and match the value in a configured profile. If the profile also requires password authentication, do that as well.

- Fallback

  Authenticate using the CLID when RADIUS is available, otherwise fall back to using password authentication.

- Called Require

  The called number must be valid and match the Calling # value in a configured profile. If the profile also requires password authentication, do that as well.

- Called Prefer

  Authenticate using the Calling # value in a configured profile if available, otherwise fall back to using password authentication.

Location: `Ethernet > Answer

` See Also: AnsOrig, Calling #, Called #

## ID Fail Busy (previously CLID Fail Busy)

Description: Specifies whether to return User Busy or Normal Call Clearing as a Cause in IDSN DISCONNECT messages when authentication fails due to a mismatch between the actual number and the expected number.

Usage: Press Enter to toggle between Yes and No. No is the default. If you choose Yes, and the ID authentication fails due to a mismatch between the actual number and the expected number, the DISCONNECT message will have the Cause value User Busy (decimal value 17). If you choose No, the Cause value will be Normal Call Clearing (decimal value 16).

Dependencies: This parameter will be N/A if Auth=None or Auth=TACACS+ in the this profile. The value set in this parameter applies to both Caller ID and Called ID authentication.

This parameter is N/A if ID Auth=Ignore.

Location: `Ethernet Profile: Ethernet > Mod Config > Auth`

See Also: Timeout Busy

## Idle

Description: In the Answer or Connection profile, specifies the number of seconds the MAX waits before clearing a call when a session is inactive. In a Port profile, it specifies the action an AIM port takes when you turn on the power, or if no call is active.

Usage: In the Answer profile or a Connection profile, specify the number of seconds a session can remain idle without being brought down. If you specify 0 (zero), MAX does not enforce a limit; an idle connection stays open indefinitely. The default setting is 120 seconds.

In a Port profile, specify one of the following values:

- None specifies that the port waits for a user to establish a call. None is the default.

- Call specifies that the port attempts to establish an outbound call whenever you turn on the power, or when no call is active.

Dependencies: In a Port profile, this parameter is not applicable when the port's current Call profile is configured for FT1 calls. If the MAX uses a port for FT1-AIM or FT1-B&O calls and Idle is set to Call in the Port profile, you must set Dial to Terminal; if the MAX uses a port for FT1-AIM or FT1-B&O calls, and Idle is set to None in the Port profile, you must set Dial to DTR. Both the local and remote ends must use the same combination of these parameters. Further, if you set Idle to None and Dial to DTR, the hosts at both ends of the connection must make DTR (Data Terminal Ready) active for the MAX to connect the switched channels.

## Idle Logout

Description: Specifies the number of minutes an administrative login can remain inactive before the MAX logs out and hangs up.

Usage: Specify a number between 0 and 60. The default setting is 0; this setting disables automatic logout.

Location: `System > Sys Config`

## Idle Pct

Description: Specifies a percentage of bandwidth utilization below which the MAX clears an MP+ call. Bandwidth utilization must fall below this percentage on both sides of the connection before the MAX clears the call.

If the device at the remote end of the link enters an Idle Pct setting lower than the value you specify, the MAX does not clear the call until bandwidth utilization falls below the lower percentage. If either end of a connection sets this parameter to 0 (zero), the MAX ignores the parameter on both sides.

Note: When bandwidth utilization falls below the Idle Pct setting on both sides of the connection, the call disconnects regardless of whether the time specified by the Idle parameter has expired.

Usage: Specify a number between 0 and 99. The default value is 0; this setting causes the MAX to ignore bandwidth utilization when determining whether to clear a call.

Dependencies: This parameter applies only to MP+ calls.

Location: `Ethernet > Answer > PPP Options, Ethernet > Connections > Encaps Options`

See Also: Call Filter, Encaps, Idle

## IF Adrs

Description: Specifies a numbered interface IP address for the MAX. Interface-based routing allows the MAX to operate more nearly the way a multi-homed Internet host behaves. In addition to the system-wide IP configuration, the MAX and the far end of the link have link- specific IP addresses. The MAX address for this connection is specified in the IF Adrs parameter. The far-end numbered interface address is specified in the WAN Alias parameter.

Usage: Specify the IP address of the numbered interface.

Example: IF Adr=10.207.23.7/24

Dependencies: This parameter does not apply if the MAX does not route IP.

Parameter Location: Ethernet > Connections > IP options

See Also: WAN Alias, Route IP

## Ignore Def Rt

Description: Specifies whether the MAX ignores the default route when updating its routing table via RIP updates. The default route specifies a static route to another IP router, which is often a local router such as a Cisco router or another kind of LAN router. When the MAX is configured to ignore the default route, RIP updates will not modify the default route in the MAX routing table.

Usage: Specify Yes or No. No is the default.

- Yes means the MAX ignore advertised default routes. This is recommended.

- No means the MAX may modify its default route based on RIP updates.

Example: Ignore Def Rt=Yes

Dependencies: This parameter is not applicable if the MAX does not route IP.

Location: `Ethernet > Mod Config > Ether Options`

## Imm. Modem Access

Description: Specifies the type of call restriction in use for the Immediate Modem feature.

Note: Previously, you could set the Imm. Modem Pwd parameter to null to allow unlimited access to the Immediate Modem feature-now you should set Imm. Modem Access to None instead. However, for compatibility reasons, the system still treats the combination of Imm. Modem Access=Global and a null Imm. Modem Pwd parameter as if Imm. Modem Access were set to None.

Usage: Specify one of the following values:

- None

  This indicates that call restriction is disabled, and that all users can place outgoing calls.

- Global

  This indicates that a single password is used to verify dialout. Anyone who knows that password can place outgoing calls. The Imm. Modem Pwd parameter specifies the password.

- User (the default)

  When per-user Immediate Modem access is enabled, the MAX requests a login name before allowing any user access to the Immediate Modem feature. It then looks for a profile with that name. If it does not find a matching profile, the MAX closes the Telnet session and rejects the request for dialout. If it does find a matching profile, it request the password (if any) associated with that profile. If the user enters the correct password, the MAX performs an additional check: it verifies that the Dialout-OK parameter is set to Yes in the Connection profile. The user is allowed access to a modem only if the user enters the proper password and has Dialout-OK set to Yes. Otherwise, the MAX closes the Telnet session and displays an appropriate message.

Example: Imm. Modem Access=User

Location: `Ethernet > Mod Config > TServ Options`

See Also: Dialout OK, Imm. Modem Pwd

## Imm. Modem Port

Description: Specifies the port number for Immediate Modem dialout. It tells the MAX that all Telnet sessions initiated with that port number want modem access.

Usage: Specify a port number (5000-65535). The default is 5000.

Location: `Ethernet > Mod Config > TServ Options`

Dependencies: This parameter is not applicable if terminal services are disabled.

See Also: Immediate Modem

## Imm. Modem Pwd

Description: Specifies a password required to dialout using the Immediate Modem service when Imm. Modem Access is set to Global. If this password is non-null, users will be prompted for a password before being allowed access to a modem and modem dialout service will be denied if the user does not enter the proper password.

Usage: Specify a password up to 64 characters.

Location: `Ethernet > Mod Config > TServ Options`

Dependencies: This parameter is not applicable if terminal services are disabled, if Immediate Modem is disabled, or if Imm. Modem Access is set to None or User.

## Immed Host

Description: Specifies the host to use for terminal server users' immediate service. Immediate service establishes the selected service as soon as the terminal server connection is established.

Usage: If the immediate service is Telnet, Raw-TCP, or Rlogin, specify the IP address or DNS hostname. If the immediate service is X25-PAD, specify the X.121 address (or mnemonic) to call for access to the PAD (Packet Assembler/Disassembler).

Example: Immed Host=host1.abc.com

Dependencies: This parameter is not applicable if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: Immed Port, Immed Service

## Immed Port

Description: Specifies the TCP port on which immediate Telnet, raw TCP, or Rlogin sessions are established as soon as the terminal server connection is established.

Usage: Specify the port number on the remote device. The default zero indicates port 23.

Dependencies: This parameter is not applicable if Immediate Service is set to X.25/PAD or if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: Immed Host, Immed Service

## Immed Service

Description: Enables a particular type of service for establishing an immediate host connection for dial-in terminal server connections (immediate mode).

Usage: Specify one of the following values:

- None (the default)

  This disables immediate mode.

- Telnet

  For telnet service, you can set the Telnet Host Auth parameter to bypass the terminal server authentication and go right to a Telnet login prompt.

- Raw-TCP

- Rlogin

- X.25/PAD

  With this setting, the call is directed to the PAD, and the MAX makes an X.25 call request with the X.121 address specified by the Immed Host parameter. The Immed Port parameter does not apply.

Dependencies: This parameter requires a host specification in the Immed Host parameter. It is not applicable if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: Immed Host, Immed Port

## Immediate Modem

Description: Enables or disables the Immediate Modem service. If Immediate Modem service is enabled, users can Telnet to a MAX to access the MAX unit's modems, so that they can place outgoing calls without going through MAX terminal server interface. The MAXDial software offers the same outgoing call ability, but through a GUI interface.

Note: The MAX provides per-user control and accounting for both the Immediate Modem feature and MAXDial to control access to the modems. See Immediate Modem Access.

Usage: Specify Yes or No. No is the default.

- Yes enables Immediate Modem service.

- No disables this service.

Location: `Ethernet > Mod Config > TServ Options

` Dependencies: This parameter is not applicable if terminal services are disabled.

See Also: Imm. Modem Port, Imm. Modem Access

## Inactivity Timer

Description: The inactivity timer specifies the number of seconds to allow a connection to remain inactive before dropping the virtual circuit.

Usage: Specify a number of seconds. The default zero disables the inactivity timer.

Example: Inactivity Timer=120

Dependencies: This parameter applies only to X.25/IP connections

Location: `Ethernet > Connections > Encaps Options`

## Inc Ch Count

Description: Specifies the number of channels the MAX adds as a bundle when bandwidth changes either manually or automatically during a call.

If the call's data service is 384K/H0 or 384KR, the value you specify should be divisible by 6, because 384 kbps is 6x64 kbps. In this case, specify a value of 6, 12, 18, 24, or 30.

If the call's data service is MultiRate or GloBanD, and the service you select is a multiple of 64 kbps, specify a value that is a multiple of 6.

MP+ calls cannot exceed 32 channels. The sum of Base Ch Count and Inc Ch Count cannot exceed the maximum number of channels available.

Usage: Specify a number of channels. The default is 1.

Example: Inc Ch Count=3

Dependencies: This parameter does not apply if all channels if the call type is Nailed. In a Call profile, this parameter applies only if the call type is AIM, FT1-AIM, FT1-B&O, or BONDING and the Call Mgm parameter is set to Manual, Dynamic, or Mode 2.

Location: `Host/Dual (Host/6) > PortN Menu > Directory, Ethernet > Connections > Encaps Options`

See Also: Base Ch Count, Dec Ch Count, Max Ch Count

## Input Sample Count

Description: Allows the PRI-T1 conversion process to use one or two sets of Goertzel samples to do the DTMF tone detection. By default, the MAX uses only one sample to decode signals from robbed-bit PBXs, because come PBX devices have a tone duration less than 50ms, which does not provide enough time to compute two sets of Goertzel samples. The PRI- T1 conversion process is more accurate when the MAX can use two samples. Using two samples is recommended when the tone duration is longer than 70ms.

Usage: Specify one of the following values:

- one (use one set of Goertzel samples)

- two (use two sets of Goertzel samples)

Example: Input Sample Count=One

Dependencies: This parameter applies only to T1 lines using PBX-T1 conversion.

Location: `Net/T1 > Line Config > Line N`

See Also: Sig Mode

## Initial Scrn

Description: Specifies the type of user interface displayed at the start of a dial-in terminal server connection.

Usage: Specify one of the following values:

- Cmd (the default) to display the command-line interface (terminal mode).

- Menu to display the menu interface (menu mode).

Location: `Ethernet > Mod Config > TServ Options

`

## Interval

Description: Specifies the number of seconds between the receipt or transmission of Combinet line-integrity packets. If the MAX does not receive a Combinet line-integrity packet within three of these intervals, it disconnects the call.

Usage: Specify a number of seconds between 5 and 50. The default is 10.

Example: Interval=10

Dependencies: This parameter applies only to Combinet connections.

Location: `Ethernet > Answer > COMB Options, Ethernet > Connections > Encaps Options`

See Also: COMB, Encaps

## IP Addr Msg

Description: Specifies a string to be printed in front of the IP address when a terminal server user initiates a PPP session.

Usage: Specify a text string up to 20 characters. The default is IP address is:

Example: IP Addr Msg=Your IP address is:

Dependencies: This parameter is not applicable when terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

## IP Adrs

Description: Specifies the LAN interface IP address.

Usage: Specify the IP address of the MAX on the local IP network or subnet.

Example: IP Adrs=10.2.1.1/24

Dependencies: This parameter does not apply if the MAX does not route IP.

Location: `Ethernet > Mod Config > Ether Options`

See Also: Encaps, Route IP

## IP Direct

Description: Specifies the IP address of a local host that all inbound IP packets on this link will be directed. When you specify an address for this parameter, the MAX bypasses all internal routing and bridging tables and sends each packet received from the remote end of the connection to the specified address. This does not affect outbound traffic. Note that the IP direct host must be on the same local network as the MAX.

Usage: Specify an IP address. The default is 0.0.0.0. If you accept the default, the MAX does not redirect traffic coming from the remote end specified by the Connection profile.

Example: IP Direct=10.2.3.4/24

Location: `Ethernet > Connections > Session Options`

See Also: Bridge, Encaps, FR Direct, RIP, Route IP

## IP Gateway Addr Msg

Description: Specifies the text the MAX displays before the MAX IP address field in the SLIP session startup message.

Usage: Specify a a text message. You can enter up to 64 characters. The default is `Gateway:`.

Dependencies: IP Gateway Addr Msg does not apply unless you set SLIP Info to Advanced.

Location: `Ethernet > Mod Config > TServ Options`

See Also: Slip Info, IP Netmask Msg

## IP Netmask Msg

Description: Specifies the text the MAX displays before the netmask field in the SLIP session startup message.

Usage: Specify a a text message. You can enter up to 64 characters. The default is `Netmask:`.

Dependencies: IP Netmask Msg does not apply unless you set SLIP Info to Advanced.

Location: `Ethernet > Mod Config > TServ Options`

See Also: Slip Info, IP Gateway Addr Msg

## IPX Alias

Description: Specifies the IPX network number assigned to a point-to-point link. This parameter is used only when the MAX operates with a non-Ascend router that uses a numbered interface. It does not apply if you are routing from one MAX to another, or to a router that does not use a numbered interface.

Usage: Specify an IPX network number. The default value is 00000000. FFFFFFFF is invalid.

Dependencies: This parameter is not applicable if the MAX does not route IPX.

Location: `Ethernet > Connections > IPX Options`

See Also: Route IPX

## IPX Enet#

Description: Specifies the IPX network number for the Ethernet interface of the MAX. The easiest way to ensure that the number is correct is to leave the default null address. This causes the MAX to listen for its network number and acquire it from another router on that interface. If you enter a number other than zero, the MAX becomes a seeding router and other routers can learn their IPX network number from the MAX. For details about seeding routers, see the Novell documentation.

Usage: Specify the IPX network number in use on the Ethernet segment to which the MAX is connected. The default 00000000 causes the MAX to learn its network number from other routers on that interface.

Example: IPX Enet #=DE040600

Dependencies: This parameter is not applicable if the MAX does not route IPX.

Location: `Ethernet > Mod Config > Ether Options`

## IPX Frame

Description: Specifies the packet frame used by the majority of NetWare servers on Ethernet. The MAX routes and spoofs only one IPX frame type (IEEE 802.2 by default), which is specified in the IPX Frame parameter. If some NetWare software transmits IPX in a frame type other than the type specified here, the MAX drops those packets, or if bridging is enabled, it bridges them. If you are not familiar with the concept of packet frames, see the Novell documentation.

Usage: Specify one of the following values:

- 802.2 (NetWare 3.12 or later)

  This setting indicates that the IPX clients and servers on the local Ethernet cable follow the IEEE 802.2 protocol for the MAC header. The framer contains the LLC (Logical Link Control) header in addition to the MAC (Media Access Control) header. This is the default.

- 802.3 (for NetWare 3.11 or earlier)

  This setting indicates that IPX clients and servers on the local Ethernet cable follow the IEEE 802.3 protocol for the MAC header, also called Raw 802.3. The frame does not contain the LLC (Logical Link Control) header in addition to the MAC (Media Access Control) header.

- SNAP

  This setting indicates that the IPX clients and servers on the local Ethernet network follow the SNAP (SubNetwork Access Protocol) for the MAC header. This specification includes the IEEE 802.3 protocol format plus additional information in the MAC header.

- Enet II

  This setting indicates that IPX clients and servers on the local Ethernet network follow the Ethernet II protocol for the MAC header.

- None disables IPX-specific features.

  If you choose this setting, the MAX can bridge or route IPX, but without watchdog spoofing or the automatic RIP and SAP handling.

Dependencies: This parameter is not applicable if the MAX does not route IPX.

Location: `Ethernet > Mod Config > Ether Options`

## IPX Net #

Description: Specifies the network number of the remote-end router. If specified, it creates a static route to that device. It is needed only when the remote-end router requires that the MAX know its network number before connecting.

Usage: Specify the remote device's IPX network number. The default 00000000 is appropriate for most installations. The default causes the MAXnot to advertise the route until it makes a connection to the remote network.

Dependencies: This parameter is not applicable if the MAX does not route IPX.

Location: `Ethernet > Connections > IPX Options`

See Also: Route IPX

## IPX Pool #

Description: Specifies a virtual IPX network to be assigned to dial-in NetWare clients. Dial- in clients do not belong to an IPX network, so they must be assigned an IPX network number to establish a routing connection with the MAX. The MAX advertises the route to this virtual network and assigns it as the network address for dial-in clients.

The dial-in Netware client must accept the network number, although it can provide its own node number or accept a node number provided by the MAX. If the client does not have a unique node address, the MAX assigns the node address as well.

Usage: Specify an IPX network number that is unique in the IPX routing domain. All dial-in clients will be assigned addresses on this virtual network.

Example: IPX Pool #=FF0000037

Dependencies: This parameter is not applicable if the MAX does not route IPX.

Location: `Ethernet > Mod Config > Ether Options`

## IPX RIP

Description: IPX RIP in a Connection profile defines how RIP packets are handled across this WAN connection. IPX RIP is set to Both by default, indicating that RIP broadcasts will be exchanged in both directions. You can disable the exchange of RIP broadcasts across a WAN connection, or specify that the MAX will only send or only receive RIP broadcasts on that connection.

Usage: Specify one of the following values:

- Both (send and receive RIP updates). This is the default.

- Send (send RIP updates but do not receive them).

- Recv (receive RIP updates but do not send them).

- Off (do not send or receive RIP updates).

Example: IPX RIP=Both

Dependencies: This parameter does not apply if Peer=Dialin or the MAX does not route IPX.

Location: `Ethernet > Connection > IPX options...`

See Also: IPX SAP, Peer

## IPX Routing

Description: This enables IPX routing mode. When you turn on IPX routing in the MAX and close the Ethernet profile, the MAX comes up in IPX routing mode, uses the default frame type 802.2 (which is the suggested frame type for NetWare 3.12 or later), and listens on the Ethernet to acquire its IPX network number from other IPX routers on that segment.

Usage: Specify Yes or No. No is the default.

- Yes enables IPX routing in the MAX.

- No disables IPX routing system-wide.

Example: IPX Routing=Yes

Dependencies: If IPX routing is disabled, the MAX can still bridge IPX packets, provided that Bridging is enabled.

Location: `Ethernet > Mod Config`

See Also: Active, Connection #, Dial Query, Hop Count, IPX Alias, IPX Enet#, Network, Node, Route IPX, Server Name, Server Type, Socket, Tick Count

## IPX SAP

Description: IPX SAP in a Connection profile defines how SAP packets are handled across this WAN connection. IPX SAP is also set to Both by default, indicating that SAP broadcasts will be exchanged in both directions. If SAP is enabled to both send and receive broadcasts on the WAN interface, the MAX broadcasts its entire SAP table to the remote network and listens for SAP table updates from that network. Eventually, both networks have a full table of all services on the WAN. To control which services are advertised and where, you can disable the exchange of SAP broadcasts across a WAN connection, or specify that the MAX will only send or only receive SAP broadcasts on that connection.

Usage: Specify one of the following values:

- Both (send and receive SAP updates). This is the default.

- Send (send SAP updates but do not receive them).

- Recv (receive SAP updates but do not send them).

- Off (do not send or receive SAP updates).

Example: IPX SAP=Both

Dependencies: This parameter does not apply if Peer=Dialin or the MAX does not route IPX.

Location: `Ethernet > Connections > IPX Options`

See Also: IPX RIP, Peer

## IPX SAP Filter

Description: Applies a SAP filter to the LAN or WAN interface. You can apply an IPX SAP filter to exclude or explicitly include certain remote services from the MAX SAP table. If you apply a SAP filter in a Connection profile, you can exclude or explicitly include services in both directions.

Usage: Specify the unique portion of the number preceding an IPX SAP Filter profile name in the IPX SAP Filters menu. The default zero means no filter is applied.

Example: IPX SAP Filter=4

Dependencies: This parameter does not apply if the MAX does not route IPX.

Location: `Ethernet > Answer > Session Options, Ethernet > Connections > Session Options, Ethernet > Mod Config > Ether Options`

## L

## L2 End

Description: Specifies CCITT Layer 2, which is used to determine the address to send when two PBX devices are connected back-to-back. In that case, one side must act as a PBX and the other side must act as an ET.

Usage: Specify one of the following values:

- b-side (the default)

- a-side (Layer 2 acts as ET)

Example: L2 End=b-side

Dependencies: This parameter applies only to E1 lines.

Location: `Net/E1 > Line Config > Line N`

See Also: L3 End, Switch Type

## L2TP Mode

Description: Specifies the system-wide type of L2TP functionality the MAX supports.

Usage: Specify one of the following values:

- LAC specifies that the MAX can function as an LAC only.

- LNS specifies that the MAX can function as an LNS only.

- Both specifies that the MAX can function as either an LAC or an LNS.

- None disables L2TP functionality on the MAX.

  None is the default.

Example: L2TP Enable=LAC

Location: `Ethernet > Mod Config > L2 Tunneling Options`

See Also: Line n tunnel type, Route n line

## L3 End

Description: Specifies CCITT Layer 3, which must be set to its default value when a DPNSS or DASS2 switch type is in use.

Usage: Specify one of the following values:

- x-side (the default)

  This value specifies that layer 3 favors the outbound call when a call collision occurs.

- y-side

Example: L3 End=x-side

Location: `Net/E1 > Line Config > Line N`

See Also: L2 End, Switch Type

## LAPB k

Description: Specifies the maximum number of sequentially numbered frames that a given DTE/DCE link may have unacknowledged at any given time. This specification is also called the Level 2 Window Size or the Frame Window Size.

Usage: Specify a number between 1 and 7. The default is 7. A higher value enables faster throughput. The value you specify must be the same for both ends of the link.

Location: `Ethernet > X.25`

See Also: LAPB N2, LAPB T1, LAPB T2

## LAPB N2

Description: This parameter indicates the retry limit-the maximum number of times the MAX can resend a frame when the LAPB (Link Access Protocol-Balanced) T1 timer expires.

Usage: Specify a number between 0 and 255. The default is 20. A higher value increases the probability of a correct transfer of data. A lower value allows for quicker detection of a permanent error condition.

Location: `Ethernet > X.25`

See Also: LAPB k, LAPB T1, LAPB T2

## LAPB T1

Description: Specifies the maximum amount of time in seconds the transmitter should wait for an acknowledgment before initiating a recovery procedure.

On a transmission line between a user and the network, a particular frame or acknowledgment may be incorrectly transmitted or simply discarded. To keep the transmitter from waiting indefinitely for an acknowledgment, you can specify the maximum amount of time the transmitter should wait.

Usage: Specify a number between 1 and 255. The default is 3. When you choose a value for this parameter, you must take into account any frame transmission and processing delays you may encounter. In most cases, you should use the default value suggested by the network.

Location: `Ethernet > X.25`

See Also: LAPB k, LAPB N2, LAPB T2

## LAPB T2

Description: This parameter determines the maximum number of milliseconds LAPB (Link Access Protocol-Balanced) waits for outgoing I-frames (Information frames) before sending a Restart-Request packet to the network. An I-frame is a frame that transports data over an access link.

Usage: Specify a number between 0 and 255. The default is 0 (zero).

Location: `Ethernet > X.25`

See Also: LAPB k, LAPB N2, LAPB T1

## LAN

Description: Specifies the ISDN subaddress associated with the MAX unit's bridge/router module or terminal server. When a call is received that includes this subaddress as part of the dialed number, the call is routed to the LAN. This is one method of routing calls. Another way to route calls to the Ethernet is to set the Ans N# parameter in the Ethernet profile.

Usage: Specify a subaddress number between 0 and 99. The default is 0.

Example: LAN=3

Dependencies: This parameter is not applicable if the Sub-Adr parameter is not set to Routing.

Location: `System > Sys Config`

See Also: Ans N#, Sub-Adr

## LAN Adrs

Description: Specifies the IP address of remote-end host or router.

Usage: Specify the IP address of the remote device.

Example: LAN Adrs=200.207.23.101/24

Dependencies: This parameter does not apply if the MAX does not support IP routing. No two calling Connection profiles should have the same LAN Adrs.

Location: `Ethernet > Connections > IP Options`

See Also: Encaps, IP Adrs, Route IP, Station

## LCN

Description: Specifies the LCN (logical channel number) to use for a PVC (Permanent Virtual Connection) using X.25

At the packet level, a number of logical channels are set up between a DTE and a DCE. Every packet exchange occurs on one of these logical channels. When a connection takes place, X.25 uses a logical channel to establish a PVC. The DCE maintains the correspondence between the logical channel and the PVC while the call takes place, and clears the PVC when the data exchange is over.

Usage: Specify a channel number. You can enter a number between 0 and 4095. The default is 0 (zero). If you accept the default, the X.25 link does not use a logical channel or PVC; the link is an SVC (Switched Virtual Connection).

Dependencies: This parameter applies only to X.25/PAD and X.25/IP connections.

Location: `Ethernet > Connections > Encaps Options`

## Length

Description: In a T1 line profile, specifies the cable length of the line from the CSU (Channel Service Unit) or other network interface unit to the MAX. The setting you indicate should reflect the longest line length you expect to encounter in your installation.

In a Firewall profile, it specifies the length of the firewall uploaded to the MAX from Secure Access Manager (SAM). In Firewall profiles, the parameter is read-only.

In a filter of type Generic, specifies the number of bytes to test in a frame, starting at the specified Offset. The MAX compares the contents of those bytes to the value specified in the filter's Value parameter. For example, with this specification:

    Filters
          Name=filter-name
          Input filters...
                In filter 01
                      Generic...
                            Forward=No
                            Offset=2
                            Length=8
                            Mask=0F FF FF FF 00 00 00 F0
                            Value=07 FE 45 70 00 00 00 90
                            Compare=Equals
                            More=No

and the following packet contents:

    2A 31 97 FE 45 70 12 22 33 99 B4 80 75

The filter applies the mask only to the eight bytes following the two-byte offset.

- In a T1 profile, specifies the length of the cable.

Usage: In a Filter profile, specify a number between 0 and 8 that defines the number of bytes to use for comparison. The default zero means no bytes are compared.

In a T1 line profile, specify one of the following values

- 1-133 ft. (the default)

- 134-266 ft.

- 267-399 ft.

- 400-533 ft.

- 534-655 ft.

## Listen X.121 Addr

Description: Specifies a listen pattern for host-initiated calls. This is similar to typing the following command in the X.25 PAD:

    * listen addr=pattern

The pattern is in the same format as an X.121 address, or sub address and can contain wild cards.

Usage: Specify an address. You can enter up to 15 characters.

Dependencies: This parameter is always applicable.

Location: `Ethernet > Connections > any Connection profile > Encaps options
Ethernet > Answer > T3POS options`

## Line n tunnel type

Description: Indicates whether the MAX should tunnel all calls received on the specified WAN line.

Usage: Specify one of the following values:

- L2TP directs the MAX to create L2TP tunnels for all calls received on the specified line.

- PPTP directs the MAX to create PPTP tunnels for all calls received on the specified line.

- None directs the MAX not to create tunnels on a per-line basis.

  None is the default.

Example: Line 1 tunnel type=None

Dependencies: Line n tunnel type applies only if you set L2TP Mode to LAC or Both.

Location: `Ethernet > Mod Config > L2 Tunneling Options`

See Also: L2TP Mode, Route n line

## Link Access Type

Description: Specifies the type of the DTE connection.

Usage: Specify one of the following values:

- Dedicated (the default)

  Specifies that the DTE connection is a permanent, leased-line connection.

- Dial

  Specifies that the DTE connection is a dial-up connection.

Dependencies: This parameter is always applicable.

Location: `Ethernet > Connections > any Connection profile > Encaps options
Ethernet > Answer > T3POS options`

## Link Comp

Description: Specifies the link compression method for a PPP, MP, and MP+ call. Both sides of the connection must set the same type of link compression or it will not be used.

Usage: Specify one of the following values:

- None (the default in the Answer profile)

- Stac (Use an Ascend modified version of draft 0 of the CCP protocol)

- Stac-9 (Use draft 9 of the Stac LZS Compression protocol)

- MS-Stac

  Use Microsoft/Stac compression (the same method as Windows95). If the caller does not acknowledge Microsoft/Stac compression, the MAX attempts to use standard Stac compression; if that does not work, it uses no compression.

Example: Link Comp=Stac

Dependencies: This parameter applies only to PPP and its multilink variants. Both sides of the link must support the same kind of compression or it is not used.

Location: `Ethernet > Answer > PPP Options, Ethernet > Connections > Encaps Options`

See Also: Compression

## Link Mgmt

Description: Specifies the link management protocol to use between the MAX and the frame relay switch. The frame relay administrator or service provider can tell you which value to use.

Usage: Specify one of the following values:

- None specifies no link management.

  The MAX assumes that the physical link is up and that all logical links (as defined by the DLCI and FR DLCI parameters) are active on the physical link.

  None is the default.

- T1.617D specifies the link management protocol defined in ANSI T1.617 Annex D.

- Q.933A the link management protocol defined Q.933 Annex A.

Location: `Ethernet > Frame Relay

` See Also: DLCI, FR DLCI

## Link Type

Description: Specifies whether an ISDN BRI line is operating in point-to-point or multipoint mode. If the MAX uses only one channel of a multipoint ISDN BRI line and another device uses the other channel, you can set one channel to unused by setting B1 Usage or B2 Usage to Unused, and enter only one SPID. The device sharing the line must enter the other assigned SPID.

Usage: Check with your carrier to find out the setting you should specify for this parameter. You can specify one of the following values:

- P-T-P specifies point-to-point mode, in which the MAX requires one phone number and no SPIDs.

- Multi-P specifies multipoint mode, in which the MAX requires two phone numbers and two SPIDs. This is the default.

Dependencies: All switch types use multi-point except the AT&T 5ESS switch.

Location: `Net/BRI > Line Config > Line N`

See Also: Pri SPID, Sec SPID, Switch Type

## LinkUp

Description: Specifies whether the Frame Relay link comes up automatically and stays up even when the last DLCI has been removed or does not come up unless a Connection profile (DLCI) brings it up, and it shuts down after the last DLCI has been removed.

Usage: Specify Yes or No. No is the default.

- Yes causes the MAX bring the link up and keep it up even if there are no active DLCIs.

- No means the link does not come up unless a Connection profile (DLCI) brings it up, and it shuts down after the last DLCI has been removed.

Dependencies: You can start and drop frame relay datalink connections by using the DO Dial and DO Hangup commands. If LinkUp is set to Yes, DO Dial brings the link down, but it will be automatically restarted. A restart will also occur if there is a Connection or Frame Relay profile invoking the datalink.

Location: `Ethernet > Frame Relay`

See Also: FR Prof, DLCI, Circuit

## List Attempt

Description: Enables or disables the DNS List Attempt feature. DNS can return multiple addresses for a hostname in response to a DNS query, but it does not include information about availability of those hosts. Users typically attempt to access the first address in the list. If that host is unavailable, the user must try the next host, and so forth. However, if the access attempt occurs automatically as part of immediate services, the physical connection is torn down when the initial connection fails. To avoid tearing down physical links when a host is unavailable, you can use the List Attempt parameter to enable the MAX to try one entry in the DNS list of hosts, and if that connection fails, to try the next entry, and so on, without losing the WAN session. The List Size parameter specifies the maximum number of hosts listed.

Usage: Specify Yes or No. No is the default.

- Yes enables a user to try the next host in the DNS list if the first Telnet login attempt fails, which may prevent the physical connection from being torn down.

- No means the connection fails if the first Telnet attempt is refused. For dial-in users, the physical connection is torn down when the initial connection fails.

Dependencies: If List Attempt = No and Enable Local DNS Table = Yes, the local DNS table has only one entry.

Location: `Ethernet > Mod Config > DNS`

See Also: List Size, Enable Local DNS Table

## List Size

Description: Specifies the maximum number of DNS addresses that are made accessible to terminal server sessions in response to a DNS query. List Size also specifies the maximum number of IP address entries in the Local DNS table.

If List Attempt=Yes and the name server returns an IP address list, the list is copied into the entry in the local DNS table that matches the host name, up to the number of entries you specify in List Size. When a list of IP addresses for an entry is automatically updated, any existing list for that entry is discarded.

Note: The number of IP addresses displayed with the dnstab entry terminal command depends upon the value you set in the List Size parameter.

Usage: Specify a number between 1 and 35. The default is 6.

Example: Following are three possible local DNS table situations:

- You have set List Size=4 and the remote DNS returns 3 addresses, the three addresses replace the entire list of four IP addresses in the local DNS table.

- You have set List Size= 35, and the remote DNS server returns only 4 addresses. The MAX places the four IP addresses in the table and sets the remaining 31 addresses in the list to zero.

- You have just changed the List Size =1. Previously, you had set List Size=10. The next time the table entry for that one IP address is updated, only the first IP address will be retained in the table, all nine others will be set to zero.

Dependencies: This parameter is applicable only when the parameter List Attempt = Yes. A local DNS table is created only if the parameter Enable Local DNS Table= Yes.

## Local Echo

Description: Allows you to configure local echo mode on a terminal server session. Local echo mode is a line-by-line mode, where the line that appears as it is typed is not actually transmitted until a carriage return is entered. If local echo is enabled, the line transmitted is echoed on the local MAX terminal screen.

Local echo allows MAX terminal server users to connect to non-standard Telnet ports and programs. If the remote server turns local echo on or off in its option negotiation for a Telnet session, this setting will override the setting made locally.

A terminal server user can override the Local Echo setting from the command line for the current session using the -e option of the Telnet command.

Usage: Specify Yes or No. No is the default.

- Yes turns on local echo.

- No disables local echo.

Dependencies: This parameter is not applicable if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ options`

## Local Profiles First

Description: Specifies whether the MAX should attempt local authentication before remote (external) authentication. By default, the MAX first attempts to authenticate the connection using local profiles. If that fails, the MAX tries to authenticate the connection using an external authentication server.

If this parameter set to No, the MAX first tries to authenticate the connection using a remote authentication server. If that fails, the MAX attempts to authenticate the connection using local profiles. In this case, some dynamic password challenges behave differently than when authentication is local. (PAP and CHAP work the same either way.)

- PAP-TOKEN

  Authentication will not produce a challenge if there is a local profile. This defeats the security of using PAP-TOKEN.

- PAP-TOKEN-CHAP

  Brings up one channel, but all other channels fail.

- CACHE-TOKEN

  If the far end of the connection has ever authenticated using a challenge, CACHE-TOKEN will not work with local profiles. If the far end has not ever authenticated, there will be no problem with the local profiles.

Note: Because the remote authentication is tried first if this parameter set to No, the MAX waits for the remote authentication to time out before attempting to authenticate locally. This timeout may take longer than the timeout specified for the connection and could cause all connection attempts to fail. To prevent this, set the authentication timeout value low enough to not cause the line to be dropped, but still high enough to permit the unit to respond if it is able to. The recommended time is 3 seconds.

Usage: Specify Yes or No. Yes is the default.

- Yes retains the default authentication order.

- No reverses the default and attempts remote authentication first.

Example: Local Profiles First=Yes

Dependencies: This parameter is not applicable if Auth is set to None. See the Note above for related dependencies.

Location: `Ethernet > Mod Config > Auth`

See Also: Auth Timeout

## Location

Description: This is an SNMP-readable parameter that specifies the physical location of the MAX. It does not affect the unit's operations.

Usage: Specify a description of the MAX unit's location. You can enter up to 80 characters.

Location: `System > Sys Config`

See Also: Contact

## Loc. DNS Tab Auto Update

Description: Enables.or disables automatic updating. When automatic updating is enabled, the list of IP addresses for each entry is replaced with a list from the remote DNS when the remote DNS successfully resolves a connection to a host named in the table.

Usage: Loc.DNS Tab Auto Update=Yes to enable automatic updating of the IP addresses in the local DNS table. No disables automatic updating. No is the default.

When automatic updating is enabled, the list of IP addresses for each entry is replaced with a list from the remote DNS when the remote DNS successfully resolves a connection to a host named on the table.

Dependencies: The Enable Local DNS Table parameter must be set to Yes.

Location: `Ethernet Profile: Ethernet > Mod Config > DNS`

## Log Facility

Description: Specifies how the Syslog host sorts system logs. The Syslog host is the station to which the MAX sends system logs.

All system logs using the same setting are grouped together in the host's file system. That is, all system logs using the Local0 facility are grouped together, all system logs using the Local1 facility are grouped together, and so on.

Usage: Specify one of the following values:

- Local0 (the default)

- Local1

- Local2

- Local3

- Local4

- Local5

- Local6

- Local7

Dependencies: This parameter applies only when Syslog=Yes.

Location: `Ethernet > Mod Config > Log`

See Also: Log Host, Syslog

## Log Host

Description: Specifies the IP address of the Syslog host-a UNIX station to which the MAX sends system logs.

Usage: Specify the IP address of Syslog host. The default value is 0.0.0.0.

Example: Log Host=10.207.23.1

Dependencies: This parameter applies only when Syslog=Yes.

Location: `Ethernet > Mod Config > Yes`

See Also: Log Facility, Syslog

## Login Host

Description: Specifies the IP address or DNS hostname of the host to which raw TCP connections will be directed.

Usage: Specify the IP address or hostname of the device.

Location: `Ethernet > Connections > Encaps Options`

See Also: Login Port

## Login Port

Description: Specifies the TCP port the raw TCP connection will use to connect to the specified host.

Usage: Specify the TCP port number on the login host. You can specify a value between 1 and 65535. The default is 1.

Location: `Ethernet > Connections > Encaps Options`

See Also: Login Host

## Login Prompt

Description: Specifies the string used to prompt for a user name when authentication is in use and an interactive user initiates a connection. If the Prompt Format parameter is set to Yes, you can include multiple lines in the login prompt by including carriage-return/line-feed (\n) and tab (\t) characters. To include an actual backslash character, you must "escape" it with another backslash. For example, you could enter this string:

    Welcome to\n\t\\Ascend Remote Server\\\nEnter your user name:

to display the following text as a login prompt:

    Welcome to
       \\Ascend Remote Server\\
    Enter your user name:

Usage: Specify up to 31 characters. The default value is Login:

Example: Login Prompt=Enter your name:

Dependencies: This parameter does not apply if terminal services are disabled. If the Prompt Format parameter is set to No, this parameter is limited to 15 characters and cannot include newlines or tabs.

Location: `Ethernet > Mod Config > TServ Options`

## Login Timeout

Description: Specifies the number of seconds a terminal-server user can use for logging in. After the specified number of seconds, the login attempt times out. A user has the total number of seconds indicated in the Login Timeout field to attempt a successful login. This means that the timer begins when the login prompt appears on the terminal server screen, and continues (is not reset) when the user makes unsuccessful login attempts.

Usage: Specify between 0 and 300 seconds. The default is 300. A zero value disables the timer.

Example: Login Timeout=300

Dependencies: This parameter does not apply if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

## LoopAvoidance

Description: Specifies the number of transit PBX devices through which a call may be routed.

Usage: Specify a number between 1 and 26. The default value is 7.

Example: LoopAvoidance=7

Dependencies: This parameter applies only to E1 lines.

Location: `Net/E1 > Line Config > Line N`

See Also: NL Value

## LQM

Description: Specifies whether the MAX requests Link Quality Monitoring (LQM) when answering a PPP call. LQM counts the number of packets sent across the link and periodically asks the remote end how many packets it has received. Discrepancies are evidence of packet loss and indicate link quality problems.

Both sides of the link negotiate the interval between periodic link quality reports; however, the interval must fall between the minimum interval (LQM Min) and the maximum interval (LQM Max).

Usage: Specify Yes or No. No is the default.

- Yes enables link quality monitoring for PPP connections.

- No turns off LQM.

Location: `Ethernet > Answer > PPP Options, Ethernet > Connections > Encaps Options

` Dependencies: This parameter applies only to PPP and its multilink variants.

See Also: Encaps, LQM Max, LQM Min

## LQM Max

Description: Specifies the maximum duration between link quality reports for PPP connections, measured in 10ths of a second.

Usage: Specify a number between 0 and 600. The default is 600.

Dependencies: This parameter applies only to PPP and its multilink variants. It is not applicable if LQM is set to No.

Location: `Ethernet > Answer > PPP Options, Ethernet > Connections > Encaps Options`

See Also: LQM, LQM Min

## LQM Min

Description: Specifies the minimum duration between link quality reports for PPP connections, measured in 10ths of a second.

Usage: Specify a number between 0 and 600. The default is 600.

Dependencies: This parameter applies only to PPP and its multilink variants. It is not applicable if LQM is set to No.

Location: `Ethernet > Answer > PPP Options, Ethernet > Connections > Encaps Options`

See Also: LQM, LQM Max

## LSA-type

Description: This specifies the OSPF ASE type of this link-state advertisement.

Usage: Specify one of the following values:

- ExternalType-1 (the default)

  A type-1 external metric is expressed in the same units as the link-state metric (the same units as interface cost). Type-1 is the default.

- ExternalType-2

  A Type-2 external metric is considered larger than any link state path. Use of type-2 external metrics assumes that routing between autonomous systems is the major cost of routing a packet, and eliminates the need for conversion of external costs to internal link-state metrics.

- Internal

  This indicates that this static route should be advertised in an internal LSA.

Dependencies: Keep this additional information in mind.

- The MAX only advertises the static route if the Static Route gateway has a corresponding entry in a Connection profile.

- When you set LSA-type to Internal, the internal LSA static route appears as a stub area to external OSPF routers.

Location: `Ethernet > Connections > OSPF Options, Ethernet > Mod Config > OSPF Option, Ethernet > Static Rtes

` See Also: Ospf-Cost

## M

## Mask

Description: In a filter of type Generic, specifies a 16-bit mask to apply to the Value before comparing it to the packet contents at the specified offset. You can use it to fine-tune exactly which bits you want to compare.

The MAX applies the mask to the specified value using a logical AND after the mask and value are both translated into binary format. The mask hides the bits that appear behind each binary 0 (zero) in the mask. A mask of all ones (FF FF FF FF FF FF FF FF) masks no bits, so the full Compare To value must match the packet contents. For example, with this filter specification:

    Filters
          Name=filter-name
          Input filters...
                In filter 01
                      Generic...
                            Forward=No
                            Offset=2
                            Length=8
                            Mask=0F FF FF FF 00 00 00 F0
                            Value=07 FE 45 70 00 00 00 90
                            Compare=Equals
                            More=No

and the following packet contents:

    2A 31 97 FE 45 70 12 22 33 99 B4 80 75

The mask is applied as shown below, resulting in a value that matches the Value.

The packet matches this filter. Because the Filter Action is "Discard", the packet will be dropped. The byte comparison works as follows:

- 2A and 31 are ignored due to the two-byte offset.

- 9 in the lower half of the third byte is ignored, because the mask has a 0 in its place. The 7 in the third byte matches the value parameter's 7 in the upper half of that byte.

- F and E in the fourth byte match the value parameter for that byte.

- 4 and 5 in the fifth byte match the value parameter for that byte.

- 7 and 0 in the sixth byte match the value parameter for that byte.

- 12 and 22 and 33 in the seventh, eighth and ninth bytes are ignored because the mask has a 0 in those places.

- 9 in the tenth byte equals the matches the value parameter's 9 in the lower half of that byte. The second 9 in the upper-half of the packet's tenth byte is ignored because the mask has a 0 in its place.

Usage: Specify a 16-bit hexadecimal number. The default of all zeroes means the MAX uses the data in the packet as is for comparison purposes.

Example: Mask=0FFFFFFF000000F0

Location: `Ethernet > Filters > Input filters > In filter N > Generic, Ethernet > Filters > Output filters > Out filter N > Generic`

## Max ATMP Tunnels

Description: Defines the maximum number of active ATMP sessions for units configured as an ATMP Home agent.

Changes take effect after the Connection Profile is saved, the connection is cleared, then reestablished.

Usage: Press Enter to open the text field. Type the number of simultaneous ATMP sessions you want to allow through this ATMP Gateway. The default, 0 (zero), disables the parameter.

Dependencies: Applies only to units configured as ATMP Home agents.

Location: `Ethernet > Connections > any profile > Session Options menu.`

See Also: ATMP Mode, ATMP Gateway

## Max Baud

Description: Specifies the highest baud rate that V.34 digital modems on the MAX should attempt to negotiate. Typically, the digital modems start with the highest possible baud rate (3360) and negotiate down to the rate accepted by the far end modem. You can adjust the maximum rate to bypass some of the negotiation cycles, provided that no inbound calls will use a baud rate higher than what you specify here.

Usage: Specify the maximum baud rate. The default is 3360 baud (the highest setting).

Dependencies: This parameter is not applicable if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: TS Enabled

## Max. Block Size

Description: Specifies maximum length of a transmission (including the length of opening frame) in bytes that the PAD must be able to accept and process from the DTE or host. This only applies to processing opening frame and to both local modes of operation.

Usage: Specify one of the following values:

- 512 (the default)

- 1024

Dependencies: Keep the following information in mind.

- The Max. Block Size may apply even if both the host and DTE initiated call default mode are non-local. This is because the mode can be changed through an opening frame, in which case this parameter applies.

Location: `Ethernet > Connections > any Connection profile > Encaps options
Ethernet > Answer > T3POS options

`

## Max Call Duration

Description: Specifies the maximum duration in minutes of an established session for an incoming call. The connection is checked once per minute, so the actual time of the call will be slightly longer (usually less than a minute longer) than the actual time you set.

Usage: Specify a value from 1-1440. The default is zero, which disables the timer.

Example: Max Call Duration=0

Location: `Ethernet > Answer > Session Options, Ethernet > Connections > Session Options`

## Max Call Mins

Dependencies: Establishes the maximum number of minutes a call can be online at the port, regardless of bandwidth, before the MAX disconnects it. This maximum limits the usage of switched channels, even if the MAX combines these channels with nailed-up ones. Although the MAX disconnects the switched channels when a call exceeds the value of Max Call Mins, the nailed-up channels remain connected.

Usage: Specify a number between 0 and 2,142,270. The default is 0. Accepting the default disables the parameter.

Location: `Port profile: Host/Dual (Host/6) > PortN Menu > Port Config`

See Also: Max DS0 Mins

## Max Ch Count

Description: Specifies the maximum number of channels that can be allocated to a multilink connection. For optimum performance, both sides of the connection should specify the same maximum channel count.

Usage: Specify a number from 1 to 32. The default setting is 1.

Example: Max Ch Count=5

Dependencies: In a Connection profile or Answer profile, this parameter applies only to MPP calls. In a Call profile, it applies only to dynamic AIM calls.

Location: `Ethernet > Answer > PPP Options, Host/Dual (Host/6) > PortN Menu > Directory > Time Period N, Ethernet > Connections > Encaps Options`

See Also: Add Pers, Base Ch Count, Call Mgm, Encaps

## Max DS0 Mins

Description: Specifies the maximum number of DS0 minutes a call can be online. In a Port profile, it applies to calls from the AIM port within the specified time period. In the System profile, it applies to calls from all ports on the MAX and to the Ethernet module.

A DS0 minute is the online usage of a single 56-kbps or 64-kbps switched channel for one minute. For example, a 5-minute, 6-channel call uses 30 DS0 minutes. When the usage exceeds the maximum specified by the Max DS0 Mins parameter, the MAX cannot place any more calls, and takes any existing calls offline.

The Max DS0 Mins parameter limits usage of switched channels, even if the MAX combines these channels with nailed-up ones; although the MAX disconnects the switched channels when a call exceeds the value of Max DS0 Mins, the nailed-up channels remain connected.

Usage: Specify a number specifying the maximum number of DS0 minutes a call can be online before the MAX disconnects it. A value of 0 (zero) is not valid for this parameter.

- In a Port profile, specify a number from 1 to 2,142,720 (default 1).

- In a System profile, specify a number from 1 to 5,713,920 (default 1).

Example: Max DS0 Mins=30

Dependencies: This parameter does not apply if DS0 Min Rst=Off.

Location: `Host/Dual (Host/6) > PortN Menu > Port Config, System > Sys Config`

See Also: DS0 Min Rst

## Max. Time (min)

Description: Specifies the maximum connect time in minutes for the ARA dial-in. The MAX initiates an ARA disconnect when the specified time is up. The ARA link goes down cleanly, but remote users are not notified. Users will find out the ARA link is gone only when they try to access a device.

Note: The Max. Time parameter is not associated with the MAX unit's idle timer.

Usage: Specify a number between 1 and the maximum number of minutes the connection should stay up. The default setting is 0 (zero); this setting indicates an unlimited connection time.

Dependencies: This parameter applies only to ARA connections.

Location: `Ethernet > Connections > Encaps Options`

See Also: Password, ARA, AppleTalk, Encaps

## Max Leases

Description: Specifies the number of dynamic addresses to assign to NAT (Network Address Translation) clients using this connection. When NAT is used, an initial dynamic address is automatically assigned via the PPP negotiations. This can be used to perform address translation for a single client on the LAN. When additional clients attempt to route packets through this connection, they must first be assigned their own dynamic address. The Max Leases parameter restricts the number of addresses to be given out through this connection, thus limiting the number of clients on the remote LAN who can access the Internet.

Usage: Specify the maximum number of addresses to assign to clients using this connection. The valid range is from 1 to 254. The default is 4.

Dependencies: This parameter does not apply if Reply Enabled is set to No.

Location: `Ethernet > Answer > DHCP options, Ethernet > Connections > DHCP options`

See Also: Reply Enabled

## Max Unsucc. Calls

Description: Specifies the maximum number of unsuccessful X.25 calls the MAX tries to place before dropping the modem connection.

Usage: Specify a number between 0 and 9999. The default is 10. A value of 0 (zero) indicates that the MAX never drops the modem connection because of unsuccessful X.25 calls.

Dependencies: This parameter applies only to X.25/PAD and X.25/IP connections.

Location: `Ethernet > Connections > Encaps Options`

## Mbone profile

Description: Specifies the name of a resident Connection profile to a multicast router on the WAN. The specified Connection profile must be resident. (It cannot be accessed via a RADIUS or TACACS server.) If the Mbone profile name is null and Multicast Forwarding is turned on, the MAX assumes that its Ethernet is the MBONE interface.

Usage: Specify the name of the Connection profile to a remote multicast router. If no name is specified, the MAX assumes the presence of a multicast router on its Ethernet interface.

Example: Mbone profile=newyork

Location: `Ethernet > Mod Config > Multicast`

Dependencies: This parameter does not apply if Multicast Forwarding is set to No.

See Also: Multicast Forwarding, Multicast Client

## MDM Trn Level

Description: Specifies the default transmit level for a digital modem. When a modem calls the MAX, the unit attempts to connect at the transmit attenuate level you specify. This is the amount of attenuation in decibels the MAX should apply to the line, causing the line to lose power when the received signal is too strong. Generally, you do not need to change the transmit level. However, when the carrier is aware of line problems or irregularities, you may need to alter the modem's transmit level.

Rockwell modem code has been modified to make the transmit level programmable, so users can change the default setting for their specific connection. Transmitting at higher level helps certain modems with near-end-echo problems.

Usage: Specify a value between -13 db and -18 db. The default is -13 db.

Example: MDM Trn Level=-13db

Dependencies: This parameter does not apply if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

## Method of host notif

Description: For DTE-initiated calls, this specifies how the host is notified of the mode of the call.

Usage: Specify one of the following values:

- None (the default)

  Specifies that the host is not notified of the mode of the call and any data in the CUD is discarded.

- CRP

  Specifies that the host is informed of the mode of the call by the DTE sending a Call Request Packet (CRP) in the CUD field of a control frame.

- MSF

  Specifies that the host is informed of the mode of the call by the DTE sending a Mode Switch Frame (MSF) after the call has been established.

Dependencies: Keep the following information in mind.

- This parameter does not apply if the opening frame is a general frame. In this case the default DTE-initiated mode is not changed.

Location: `Ethernet > Connections > any Connection profile > Encaps options
Ethernet > Answer > T3POS options

`

## Metric

Description: In a Connection or Route profile, specifies a RIP metric (a virtual hop count) associated with the IP route. In the Answer profile, it specifies the RIP metric of the IP link when the MAX validates an incoming call using RADIUS or TACACS and Use Answer as Default is enabled.

The specified metric is a virtual hop count. The actual hop count includes the metric of each switched link in the route.

If two routes have the same preference value, the MAX chooses the route with the lowest metric. If you enable RIP (Routing Information Protocol) across the WAN in a Connection profile or an Answer profile, the hop count for the route can differ from the value of the Metric parameter in the Route profile because the MAX always uses the lower hop count.

Usage: Press Specify a number between 1 and 15. The default setting is 7. The higher the number you specify, the less likely that the MAX will bring the link or route online.

Example: Metric=4

Dependencies: This parameter does not apply if the MAX does not route IP. In the Answer profile, the Use Answer as Default parameter must also be enabled.

Location: `Ethernet > Answer > IP Options, Ethernet > Connections > IP Options, Ethernet > Static Rtes`

See Also: Private, RIP

## Min Ch Count

Description: Specifies the minimum number of channels that can be established for a multilink call. If this number of channels is not available, the multilink session is not established. For optimum performance, both sides of the multilink connection should set this parameter to the same value.

Usage: Specify a number between 1 and the maximum channel count. The default setting is 1.

Example: Min Ch Count=1

Location: `Ethernet > Answer > PPP Options, Ethernet > Connections > Encaps Options, Host/Dual (Host/6) > PortN Menu > Directory > Time Period N`

See Also: Call Mgm, Max Ch Count

## Modem Dialout

Description: Specifies whether an operator can use this MAX unit's V.34 digital modems to dial out from the terminal server interface. Once the connection is established, the user can issue AT commands to the modem as if connected locally to the modem's asynchronous port. If you set this parameter to No while users have active dialout connections, those connections are not affected. However, no new modem dialouts will be allowed.

Usage: Specify Yes or No. No is the default.

- Yes enables terminal-server users to dial out using the MAX unit's digital modems.

- No disables modem dialout.

Dependencies: This parameter does not apply if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Option`

See Also: TS Enabled, Immediate Modem

## Modem Ringback

Description: By default, when the MAX answers an analog modem call, it generates a ringback tone that the calling modem hears, and then begins the modem protocol. Most modems ignore the ringback tone. However, some older modems require the MAX to generate a ringback tone.

Usage: Specify one of the following values:

- Yes specifies that the MAX generates a ringback tone.

  This is the default.

- No specifies that the MAX does not generate a ringback tone.

Location: `Ethernet > Mod Config

`

## Modem:NumPlanID

Description: Modem:NumPlanID is used for outbound calls made by the MAX on PRI lines so that the switch can properly interpret the phone number dialed. Ask your PRI provider for details on when to use each of the following settings. This parameter specifies NumberPlanID field in the called party's information element.

Note: This parameter applies only to calls placed by the digital modems in the MAX; that is, modem dial-out.

Usage: Specify one of the following values:

- Unknown (NumberPlanID=0)

- ISDN (the default) (NumberPlanID=1)

- Private (NumberPlanID=9)

Location: `Net/T1 > Line Config (Line profile)

` See Also: Modem:PRI # Type, NumPlanID (Call and Connection profiles), T1-PRI:NumPlanID (System profile)

## Modem:PRI # Type

Description: Modem:PRI # Type is used for outbound calls made by the MAX on PRI lines so that the switch can properly interpret the phone number dialed. Ask your PRI provider for details on when to use each of the following settings. This parameter specifies the TypeOfNumber field in the called party's information element.

Note: This parameter applies only to calls placed by the digital modems in the MAX; that is, modem dial-out.

Usage: Specify one of the following values:

- National specifies phone numbers within the U.S. (TypeOfNumber=2)

- Intl specifies phone numbers outside the U.S. (TypeOfNumber=1)

- Local specifies phone numbers within your Centrex group. (TypeOfNumber=4)

- Abbrev. specifies that the phone number is abbreviated. (TypeOfNumber=6)

- NetSpecific (currently not implemented) specifies that the network you are connected to understands the phone number (TypeOfNumber=3)

- Unknown (the default) specifies that the phone number is none of the above. (TypeOfNumber=0)

Location: `Net/T1 > Line Config (Line profile)

` See Also: Modem:NumPlanID, NumPlanID (Call and Connection profiles), T1-PRI:NumPlanID (System profile)

## Module Name

Description: In the Ethernet profile, this assigns an optional name to the Ethernet interface. In a Host-Interface profile, it assigns a name to an AIM port module, which is sent to the remote end of the connection.

Usage: Specify a name containing up to 16 characters. For the Ethernet interface, you can leave this parameter blank.

Location: `Ethernet > Mod Config, Host/Dual (Host/6) > Mod Config, Serial WAN > Mod Config`

## More

Description: In a filter of type Generic, specifies whether the MAX includes the next filter condition before determining whether the frame matches the filter. If checked, the current filter condition is linked to the one immediately following it, so the filter can examine multiple non- contiguous bytes within a packet. In effect, this parameter marries the current filter to the next one, so that the next filter is applied before the forwarding decision is made. The match occurs only if both non-contiguous bytes contain the specified values.

Usage: Specify Yes or No. No is the default.

- Yes links the current filter rule to the next one, so the next filter is applied before the forwarding decision is made.

- No does not link the current filter rule. The forwarding decision is made based solely on this rule.

Example: More=Yes

Dependencies: The next filter must be enabled.

Location: `Ethernet > Filters > Input filters > In filter N > Generic, Ethernet > Filters > Output filters > Out filter N > Generic`

## MP

Description: This enables incoming Multilink PPP (MP) connections, which use the encapsulation defined in RFC 1990. MP enables the MAX to interact with Multilink PPP- compliant equipment from other vendors to use multiple channels for a call. Both sides of the connection must support MP.

Usage: Specify Yes or No. Yes is the default.

- Yes means the MAX answers MP calls, provided that they meet all other connection criteria.

- No means the MAX will not accept inbound MP calls.

Location: `Ethernet > Answer > Encaps

` See Also: Encaps

## MPP

Description: Enables incoming MP+ (Multilink Protocol Plus) connections, which use PPP encapsulation with Ascend extensions. MP+ enables the MAX to connect to another Ascend unit using multiple channels.

Usage: Specify Yes or No. Yes is the default.

- Yes means the MAX answers MP+ calls, provided that they meet all other connection criteria.

- No means the MAX will not accept inbound MP+ calls.

Location: `Ethernet > Answer > Encaps

` See Also: Encaps, MP

## MRU

Description: Specifies the maximum number of bytes the MAX can receive in a single packet. Usually the default is the right setting, unless the far end requires a lower number.

Usage: Specify a number lower than the default MRU if the far end requires it.

- In the Answer or a Connection profile, specify a number between 1 and 1524.

- In a Frame Relay profile, specify a number between 128 and 1600.

## Multicast Client

Description: Enables the MAX to respond to multicast clients on the WAN link. Clients cannot be supported on the MBONE interface, so this means another WAN link or the local Ethernet supports a multicast router.

When this parameter is set to Yes, the MAX begins handling IGMP requests and responses on the interface. It does not begin forwarding multicast traffic until the rate limit is set.

Usage: Specify Yes or No. No is the default.

- Yes enables the MAX to respond to IGMP client requests and responses on the interface.

- No means the MAX does not respond to multicast clients on the interface.

Example: Multicast Client=Yes

Dependencies: This parameter is not applicable if Multicast Forwarding is disabled or if the Connection profile is the Mbone profile (linking to a remote multicast router). See Multicast Rate Limit for related dependencies.

Location: `Ethernet > Connections > IP options`

See Also: Multicast Rate Limit

## Multicast Rate Limit

Description: Specifies the rate at which the MAX accepts multicast packets from clients on this interface. It does not affect the MBONE interface.

Note: By default, the Rate Limit t parameter is set to 100. This disables multicast forwarding on the interface. The forwarder handles IGMP packets, but does not accept packets from clients or forward multicast packets from the MBONE router.

To begin forwarding multicast traffic on the interface, you must set the rate limit to a number less than 100. For example if you set it to 5, the MAX accepts a packet from multicast clients on the interface every 5 seconds. Any subsequent packets received in that 5-second window are discarded.

Usage: Specify a number lower than the default 100 to begin forwarding multicast traffic on the interface.

Example: Multicast Rate Limit=5

Dependencies: This parameter has no effect when applied to the MBONE interface.

## N

## N2 Retransmission Count

Description: Specifies the retry limit-the maximum number of times the MAX can resend a frame on an X.75 connection when the T1 Retransmission Timer expires.

Usage: Specify a number between 2 and 15. The default value is 10. A higher value increases the probability of a correct transfer of data. A lower value allows for quicker detection of a permanent error condition.

Location: `Ethernet > Answer > X.75 Options`

See Also: Frame Length, K Window Size, T1 Retransmission Timer, X.75

## N391

Description: Specifies the interval at which the MAX requests a Full Status Report on a frame relay link.

Usage: Specify a number from 1 to 255 seconds. The default is 6.

Example: N391=15

Dependencies: This parameter does not apply if FR Type is DCE.

Location: `Ethernet > Frame Relay`

See Also: Link Mgmt

## Nailed Grp

Description: Specifies a number assigned to a group of nailed channels or a serial WAN port. In a Frame Relay or X.25 profile, it assigns those channels to the link represented by the profile. Only one active link can be assigned to use a particular group number.

Usage: In a serial WAN profile, specify a number that will represent this port's bandwidth. It can be a number between 1 and 60 (default 1). In a Frame Relay or X.25 profile, specify the number assigned to nailed T1 or serial WAN bandwidth.

Example: Nailed Grp=5

Location: `Ethernet > Frame Relay, Serial WAN > Mod Config, Ethernet > X.25`

See Also: Activation, Call Type, Ch N Prt/Grp, Group

## Name

Description: Specifies the name of a profile, host, or user.

Note: When the Name parameter specifies an existing host, user, the MAX system itself, or a Firewall profile, the name is case-sensitive. The name you specify must be unique within the list of profiles of the same type. In addition, Ascend strongly recommends that you do not use the same name for a Names / Passwords profile and a Connection profile.

Usage: Specify a name.

- In most profiles, the name can contain up to 16 characters.

- In the X.25 profile, the name is limited to 15 characters.

- In the Names / Passwords profile, Route profile, and SNMP Traps profile, the name can contain up to 31 characters.

Example: Name=PacBell

Location: `Host/Dual (Host/6) > PortN Menu > Directory, Host/BRI > Line Config, Net/BRI > Line Config, Net/T1 > Line Config, Net/E1 > Line Config, BRI/LT > Line Config, System > Destinations, System > Dial Plan, Ethernet > Filters, Ethernet > Firewalls, Ethernet > Frame Relay, Ethernet > IPX SAP Filters, Ethernet > Static Rtes, System > Security, Ethernet > SNMP Traps, System > Sys Config, Ethernet > X.25, Ethernet > Names / Passwords,`

## Net Adrs

Description: In a Bridge profile, specifies the IP address of a device at the remote end of the link. If you are bridging between two segments of the same IP network, you can use the Net Adrs parameter in a Bridge profile to enable the MAX to respond to ARP requests while bringing up the bridged connection. If an ARP packet contains an IP address that matches the Net Adrs parameter of a Bridge profile, the MAX responds to the ARP request with the Ethernet (physical) address specified in the Bridge profile and brings up the specified connection. In effect, the MAX as a proxy for the node that actually has that address.

Usage: Specify the IP address of the device on the remote network.

Example: Net Adrs=10.207.23.101/24

Location: `Ethernet > Bridge Adrs`

See Also: Enet Adrs

## NetWare t/o

Description: Specifies the number of minutes the MAX will enable clients to remain logged in to a NetWare server even though their IPX connection has been torn down.

NetWare servers send out NCP watchdog packets to monitor which logins are active and logout inactive clients. Only clients that respond to watchdog packets remain logged in.

Repeated watchdog packets would cause a WAN connection to stay up, but if the MAX simply filtered those packets, client logins would be dropped by the remote server. To prevent repeated client logouts while allowing WAN connections to be brought down in times of inactivity, the MAX responds to NCP watchdog requests as a proxy for clients on the other side of an offline IPX routing or IPX bridging connection. Responding to these requests is commonly called watchdog spoofing.

To the server, a spoofed connection looks like a normal, active client login session, so it does not log the client out. The timer begins counting down as soon as the link goes down. At the end of the selected time, the MAX stops responding to watchdog packets and the client-server connections may be released by the server. If there is a reconnection of the WAN session before the end of the selected time, the timer is reset.

Note: The MAX filters watchdog packets automatically on all IPX routing connections and all IPX bridging connections that have watchdog spoofing enabled. The MAX applies a call filter implicitly, which prevents the Idle timer from resetting when IPX watchdog packets are sent or received. This filter is applied after the standard data and call filters.

Usage: Specify a number of minutes from 0 to 65535. The default value is 0 (zero); when you accept the default, the MAX responds to server watchdog requests indefinitely.

Example: NetWare t/o=30

Dependencies: This parameter does not apply if the MAX does not support IPX.

Location: `Ethernet > Connections > IPX Options`

See Also: Handle IPX

## Net End

Description: Used in conjunction with Net Start to indicate the end of the zone range that defines the networks available for packets that are to be routed to this static route. If the MAX is an AppleTalk router, it brings up the line when it receives packets addressed to the network number (defined by Net Start and Net End) or zone name specified for the remote connection, and routes packets to the appropriate network or zone.

Usage: Valid entries for this field are in the range from 1 to 65199. If there are other AppleTalk routers on the network, it is necessary to configure the network ranges to coincide with the other routers on the LAN.

Dependencies: The following must be true:

- AppleTalk=Yes in the Ethernet Configuration menu.

- AppleTalk Router=On in the profile's AppleTalk Options submenu.

- Peer=Router in the profile's AppleTalk Options submenu.

Location: `Ethernet > IPX Routes`

See Also: Route IPX, Network

## No Trunk Alarm

Description: Specifies whether the back panel alarm relay closes when all T1 PRI lines (or trunks) go out of service. The MAX has an alarm relay whose contacts remain open on the back panel's alarm relay terminal block during normal operation. If you enable them, the alarm relay contacts close during loss of power, hardware failure, or a system reset. The No Trunk Alarm parameter enables you to specify whether the contacts also close when all T1 PRI lines go out of service.

Usage: Specify Yes or No. No is the default.

- Yes means the MAX closes the back panel alarm relay when all trunks go out of service.

- No means the MAX records the event in the log but does not close the alarm relay.

Location: `System > Sys Config

`

## NSSA-Type

Description: Specifies whether or not area border routers convert this ASE type-7 to an ASE type-5 LSA. It applies only when the MAX is routing within an OSPF NSSA (that is, where AreaType is set to NSSA on all interfaces running OSPF). ASE type-7s can be imported only from static route definitions. NSSAs are described in RFC 1587.

Usage: Specify one of the following values:

- N/A (the default)

- Advertise (for area border routers to convert this type-7 to a type-5).

- DoNotAdvertise (for area border routers not to convert this type-7 to a type-5)

Dependencies: Keep this additional information in mind:

- Third Party is not applicable when the MAX is configured as an NSSA.

- NSSA-Type is not applicable unless Area-Type is set to NSSA.

Location: `Ethernet > Static Rtes > any Static Rtes profile

## O

## Offset

Description: In a filter of type Generic, specifies a byte-offset from the start of a frame to the data in the packet to be tested against this filter. For example, with this filter specification:

    Filters
          Name=filter-name
          Input filters...
                In filter 01
                      Generic...
                            Forward=No
                            Offset=2
                            Length=8
                            Mask=0F FF FF FF 00 00 00 F0
                            Value=07 FE 45 70 00 00 00 90
                            Compare=Equals
                            More=No

and the following packet contents:

    2A 31 97 FE 45 70 12 22 33 99 B4 80 75

The first two byes in the packet (2A and 31) are ignored due to the two-byte offset.

Note: If the current filter is linked to the previous one (if More=Yes in the previous filter), the offset starts at the endpoint of the previous segment.

Usage: Specify a number indicating a byte-offset.

Example: Offset=2

Location: `Ethernet > Filters > Input filters > In filter N > Generic, Ethernet > Filters > Output filters > Out filter N > Generic`

## Operations

Description: Enables or disables permission to view MAX profiles and to change the value of any parameter. When it is disabled, users can view MAX profiles, but cannot change the value of any parameter (read-only security). In addition, when this permission is disabled, users cannot access most DO commands. Only DO Esc, DO Close Telnet, and DO password are available.

Note: If this permission is disabled, all other permissions are disabled as well.

Usage: Specify Yes or No. Yes is the default.

- Yes means the operator can view and edit profiles.

- No disables this permission as well as all other permissions in the Security profile.

Example: Operations=No

Location: `System > Security`

## Option

Description: Specifies the criteria the MAX uses to select a trunk group when it places a call from a Destination profile. Each Destination profile contains six Call-by-Call N and Dial N# parameters. Therefore, you can configure up to six options for reaching the destination device. The Option parameter helps the MAX select which option to use.

Usage: Specify one of the following values:

- 1st Avail specifies that the MAX selects the first trunk group that has enough available bandwidth to meet the base bandwidth requirements of the Call profile (as defined by the Base Ch Count parameter).

  If no group has enough bandwidth, the MAX drops the call.

  1st Avail is the default.

- 1st Active specifies the first trunk group that has at least one available channel.

  If you choose this setting, set the Port profile parameter Fail Action=Reduce so that the MAX does not disconnect the call even if the full base bandwidth specified by Base Ch Count is not available.

- Any specifies that the MAX uses any combination of circuits from any trunk group to make the call.

  Note that the MAX does not allow you to combine channels from trunk groups of different carriers to obtain a full base bandwidth.

Location: `System > Destinations

## OSPF ASE Preference

Description: Specifies the OSPF ASE Preference the MAX uses when importing an ASE.

Usage: Specify a value from 0 to 255. A value of 255 means that the MAX never puts any ASEs into the routing table.

Example: The default route preferences are:

- Connected routes 0

- OSPF internal routes 10

- ICMP routes 30

- Static routes 60

- RIP routes 100

- Unconnected WAN routes 120

- OSPF ASE 150

- Do not use route 255

Dependencies: Keep this additional information in mind.

- When specifying a preference for a route, make sure that routes that are learned from more reliable sources have a lower preference (and are therefore more likely to be used).

- When specifying a preference for a route, you should set a lower preference for connected routes that for disconnected routes.

Location: `Ethernet > Mod Config > Route Pref

`

## OSPF Preference

Description: Specifies the preference value for routes learned from the OSPF protocol.

When choosing which routes to put in the routing table, the router first compares the OSPF Preference values, preferring the lower number. If the OSPF Preference values are equal, the router compares the Metric values, using the route with the lower Metric. These are the default values for other types of routes:

- Routes learned from ICMP Redirects=30

- Routes learned from RIP=100

- Static routes from IP address pools, RADIUS authentication, and the terminal server iproute add command=100

- Static routes in an IP Route profile or Connection profile=100

Usage: Specify a number between 0 and 255. The default value is 10. Zero is the default for connected routes (such as the Ethernet). The value of 255 means Do not use this route.

Location: `Ethernet > Mod Config > Route Pref`

## Ospf-Cost

Description: Specifies the cost of an OSPF route. The interpretation of this cost depends on the type of external metrics set in the ASE-type parameter. If the MAX is advertising Type 1 metrics, OSPF can use the specified number as the cost of the route. Type 2 external metrics are an order of magnitude larger. Any Type 2 metric is considered greater than the cost of any path internal to the AS (autonomous system).

Usage: Specify a number greater than zero. The default is 1.

Example: Ospf-Cost=1

Location: `Ethernet > Static Rtes`

See Also: ASE-type, ASE-tag

## Own Port Diag

Description: Enables or disables permission to perform the commands in the Port Diag menu for the AIM port that was called.

Note: To completely disable the operator's ability to perform diagnostics for the called port, you must also disable All Port Diag.

Usage: Specify Yes or No. Yes is the default if All Port Diag is set to No.

- Yes means the operator can use the diagnostic commands in the Port Diag menu for the AIM port that was called.

- No disables this permission.

Dependencies: This parameter is not applicable if the Operations permission is disabled or if All Port Diag is set to Yes.

Location: `System > Security`

See Also: All Port Diag

## P

## Packet Characters

Description: Specifies the minimum number of bytes of received data that should accumulate before the data is passed up the protocol stack for encapsulation.

Usage: Specify an integer between 0 and 500. The default value is 0 (zero).

Dependencies: If your application is so specialized that it demands you use this parameter, be sure to set the Packet Wait Time parameter to an appropriate value. This parameter does not apply if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: Packet Wait Time

## Packet Wait time

Description: Specifies the maximum amount of time in milliseconds that any received data can wait before being passed up the protocol stack for encapsulation.

Usage: Specify an integer between 0 and 600 milliseconds. The default value is 0 (zero).

Dependencies: If your application is so specialized that it demands you use this parameter, be sure to take into account your modem speeds when calculating its value. This parameter does not apply if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: Packet Characters

## Palmtop

Description: Specifies whether the MAX enables or disables access to AIM ports through the Palmtop Controller. If it is restricted, the operator cannot use commands specific to an AIM port, cannot access the System menus, Network menus, and Host-interface profiles, and cannot edit parameters specific to an AIM port, unless the operator is doing so through the base system's Palmtop port and the Palmtop Port # parameter enables access to the port.

If you are operating a MAX through a Palmtop port, you can change your access from Full to Restrict, but you cannot change your access from Restrict to Full. Only a terminal connected to the Control port (the back panel's DE-9 connector) can provide full access.

Usage: Specify one of the following values:

- Full (the default) specifies that access to the Palmtop port is unrestricted.

- Restricts specifies that the MAX restricts operator access to a Palmtop port.

Location: `Host/Dual (Host/6) > Mod Config

` See Also: Palmtop Port #

## Palmtop Menus

Description: Specifies whether the user of a Palmtop Controller connected to a Palmtop port has access to the standard set of menus, the command-line interface, or the simplified menus.

Usage: Specify one of the following values:

- Standard (the default) means the Palmtop port has access to the standard set of menus.

- MIF specifies that the Palmtop port has access to the command-line interface.

- Limited specifies that the Palmtop port has access to the simplified menus.

Location: `Host/Dual (Host/6) > Mod Config

`

## Palmtop Port #

Description: Specifies the AIM port to which a Palmtop port has access if Palmtop access is restricted.

Usage: Specify the number of an AIM port. If you enter 0 (zero), the user of the Palmtop port has access to any AIM port.

Location: `Host/Dual (Host/6) > Mod Config`

See Also: Palmtop

## Parallel Dial

Description: Specifies the number of channels that the MAX can dial simultaneously over the T1 PRI line, or that the MAX can disconnect simultaneously. Although you can specify any number of channels, the initial number of channels in a connection never exceeds the value of the Base Ch Count parameter. Similarly, when the MAX adds or subtracts channels, the values for Max Ch Count and Min Ch Count override any setting for Parallel Dial.

Note: If calls from the U.S. to another country have trouble establishing an initial connection at the full bandwidth, reduce the Parallel Dial parameter to a value of 2 or 1.

Usage: Specify a number between 1 and 12. The default is 5.

Location: `System profile: System > Sys Config`

See Also: Base Ch Count

## Passwd

Description: Specifies the terminal-server password (Ethernet profile) or the password required to authenticate a Security profile (Security profile). The first Security profile, Default, has no password.

Note: Passwords are case-sensitive.

Description: Specifies the prompt the terminal server displays when asking the user for his or her password.

Usage: Specify up to 31 characters. The default value is Password:

Dependencies: This parameter does not apply if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

## Password

Description: Specifies the password that an incoming ARA caller must supply (Connection profile) or the password the foreign agent must specify under ATMP (Ascend Tunnel Management Protocol) in order to access this unit (Ethernet profile).

Note: Passwords are case-sensitive.

Usage: Specify up to 20 characters.

Dependencies: In a Connection profile, this parameter is not applicable unless Encaps is set to ARA. In the Ethernet profile, it is not applicable unless ATMP is enabled and the ATMP Mode is Home.

## Password Reqd

Description: Specifies that a password will be required to authenticate Combinet connections.

Usage: Specify Yes or No. No is the default.

- Yes means the MAX requires a password from all incoming calls from a Combinet bridge.

- No means a password is not required for Combinet calls.

Example: Password Reqd=Yes

Dependencies: This parameter applies only to Combinet connections.

Location: `Ethernet > Answer > COMB Options, Ethernet > Connections > Encaps Options`

See Also: COMB, Encaps, Recv PW, Send PW, Station

## Pbx Type

Description: Specifies the signaling conversion the MAX provides when the signaling mode is PBX T1 for the second T1 line.

Usage: Specify one of the following values:

- Leased 1:1 specifies that line #1 uses inband signaling and that line #2 consists entirely of nailed-up and unused channels.

  Each channel of line #1 must have a unique phone number. When any unused channel on line #1 indicates that it has an incoming call, the MAX answers the call and connects it to the same channel in line #2, if that channel is nailed up. If the channel on line #2 is unused, the MAX handles the call in the usual manner. The call remains connected until the caller hangs up.

- Voice specifies that line #1 uses ISDN D-channel signaling and that line #2 uses inband signaling.

  The device connected to line #2 views the MAX as a switch. A switch is the device that connects the calling party to the answering party. The MAX switches an incoming call on line #1 to line #2 only if it is a voice-service call.

- Data specifies that line #1 uses ISDN D-channel signaling and that line #2 uses inband signaling.

  When you set PBX Type=Data, the MAX switches an incoming call on line #1 to line #2 only if its data service type matches the data service specified by the Ans Service parameter, and only if its phone number matches the phone number specified by the Ans # parameter.

Dependencies: The setting you specify for PBX Type affects the Ans Service parameter in these ways:

- If you choose PBX Type=Leased 1:1, the Ans Service parameter does not apply.

- If you choose PBX Type=Voice, Ans Service must be set to Voice.

- If you choose PBX Type=Data, Ans Service can have any valid value, including Voice; however, the MAX does not generate call progress tones, and does not send call information messages.

Location: `Net/T1 > Line Config > Line N

` See Also: Ans Service, Ans #, Sig Mode

## Peer

Description: Specifies whether the remote IPX caller is a router or a dialin client. The Answer profile > IPX Options > Peer parameter specifies how the MAX negotiates IPX, with callers that have no configured Connection profile, assuming them to be either IPX routers or IPX clients.

Usage: Specify one of the following values:

- Router (the default) specifies that the caller is an IPX router.

- Dialin specifies a dialin client.

  Dial-in NetWare clients do not have an IPX network address. To allow those clients an IPX routing connection to the local network, the MAX must assign the client an IPX network address from a virtual IPX network defined in the IPX Pool parameter.

  For dialin clients, the MAX does not send RIP and SAP advertisements across the connection and ignores RIP and SAP advertisements received from the far end. However, it does respond to RIP and SAP queries received from dial-in clients

Dependencies: This parameter does not apply if IPX routing is not enabled. It requires that a virtual IPX network number be provided in the IPX Pool parameter.

Location: `Ethernet > Connections > IPX Options
Ethernet > Answer > IPX Options`

See Also: IPX Pool#

## Peer (AppleTalk Options)

Description: Indicates whether the connection for this profile is a single-user PPP connection or a router.

Usage: Select Peer=Dialin to indicate that the profile is for a single user PPP connection. All other fields in the AppleTalk options menu are N/A. If you select Peer=Dialin, you have completed the configuration; close the AppleTalk Options menu and save your changes.

Select Peer=Router to indicate that the profile is for a connection with a router (such as an Ascend Pipeline unit).

Dependencies: If you select Peer=Router, you will need to configure the other fields in the AppleTalk options menu. You must select the following:

- Route Appletalk=Yes in the PPP options menu of the Answer profile.

- AppleTalk=Yes in the Ethernet Configuration menu.

- AppleTalk Router=On in the profile's AppleTalk Options submenu.

## Pkt Audio Mode

Description: Specifies the type of voice compression and coding used with any MultiVoice call. MultiVoice calls are compressed before the MultiVoice Gateway sends them across an IP network.

Usage: Specify one of the following values:

- G.711 U Law

  Appropriate in T1 environments. The MultiVoice Gateway sends digitized voice at 64 Kbps and provides toll quality voice on managed IP networks with sufficient available bandwidth.

  This is the default for MAX T1 units.

- G.711 A Law

  Appropriate in E1 environments. The MultiVoice Gateway sends digitized voice at 64 Kbps and provides toll quality voice on managed IP networks with sufficient available bandwidth.

  This is the default for MAX E1 units.

- G.729

  The MultiVoice Gateway sends digitized voice at 8 Kbps, is a low-complexity coding algorithm, and provides toll quality voice on managed IP networks.

Example: Pkt Audio Mode=G.729

Dependencies: Pkt Audio Mode only applies if the MAX acts as a MultiVoice Gateway.

## Pool

Description: Specifies an IP address pool from which the caller will be assigned an IP address. If the Pool parameter is null but all other configuration settings enable dynamic assignment, the MAX gets IP addresses from the first defined address pool.

You can define up to 10 IP address pools in the vt100 interface. RADIUS supports up to 50 address pools.

Usage: Specify the number of the pool. The default is 1.

Location: `Ethernet > Connections > IP Options`

See Also: Assign Adrs, Pool # Count, Pool # Start

## Pool #N count (N=1-10)

Description: Specifies how many IP addresses are in the numbered pool (up to 254). N represents the number of the pool, which may be 1 through 10.

Note: Addresses in a pool do not accept a netmask modifier, because they are advertised as host routes. If you allocate IP addresses on a separate IP network or subnet, make sure you inform other IP routers about the route to that network or subnet.

Usage: For each pool, specify a number between 0 and 254.

Dependencies: The starting address must be specified in the Pool #N start parameter.

Location: `Ethernet > Mod Config > WAN Options`

See Also: Pool only, Pool #N start

## Pool only

Description: Instructs the MAX to hang up if a caller rejects the dynamic assignment. During PPP negotiation, a caller may reject the IP address offered by the MAX and present its own IP address for consideration. Connection profiles compare IP addresses as part of authentication, so the MAX would automatically reject such a request if the caller has a Connection profile. However, Names/Passwords profiles have no such authentication mechanism, and could potentially allow a caller to spoof a local address.

Usage: Specify Yes or No. No is the default.

- Yes means the caller must accept dynamic assignment. This is recommended if Names/Passwords profiles are in use.

- No means the MAX allows the caller to reject the IP address offered by the MAX and present its own IP address for consideration.

Dependencies: At least one address pool must be defined, and addresses must be available.

Location: `Ethernet > Mod Config > WAN Options`

See Also: Pool # Count, Pool # Start

## Pool #N name (N=1-10)

Description: Specifies the name of an IP address pool

Usage: Specify a name. You can enter up to 10 characters. The first character cannot be a number.

Location: `Ethernet > Mod Config > WAN Options`

## Pool #N start (N=1-10)

Description: Specifies the first address in a block of contiguous addresses on the local network or subnet. The Pool#1 count parameter specifies the number of contiguous addresses in that pool

Usage: Specify the first IP address in the pool. The address you specify does not need to be on the same LAN segment as the MAX. The default is 0.0.0.0.

Example: Pool #1 Start=200.207.23.1

Dependencies: The number of addresses in the pool must be specified in the Pool #N count parameter.

Location: `Ethernet > Mod Config > WAN Options`

See Also: Pool #N count, Pool only

## Pool Number

Description: Specifies the IP address pool to use to assign addresses to NAT clients.

Usage: Specify the IP address pool to use to assign IP addresses to clients using this connection. The valid range is from 0 to 150 (RADIUS) or 0 to 10 (pool configuration in the Ethernet profile). The default is 0. A value of 0 means the MAX will assign any address from any available pool.

Dependencies: This parameter does not apply if Reply Enabled is set to No.

Location: `Ethernet > Answer > DHCP options, Ethernet > Connections > DHCP options`

See Also: Reply Enabled

## Pool OSPF Adv Type

Description: Specifies how to import summarized pool addresses into OSPF.

Usage: Specify one of the following values:

- Type-1 (the default) instructs the MAX to import the pool addresses into OSPF as external Type-1 routes.

- Type-2 instructs the MAX to import the pool addresses into OSPF as external Type-2 routes.

- Internal instructs the MAX to import the pool addresses into OSPF as Intra-Area routes.

Dependencies: Pool OSPF Adv Type applies if you must set Pool Summary=Yes and enable OSPF. For a change in the Pool OSPF Adv Type setting to take effect, you must reset the MAX.

Location: `Ethernet > Mod Config > WAN Options`

See Also: Active, Pool Summary

## Pool Summary

Description: Indicates that network summarization is in use.

Network summarization reduces the size of route advertisements by summarizing a series of host routes into a network advertisement. Packets destined for a valid host address on that network are routed to the host, and packets destined for an invalid host address are rejected with an ICMP "host unreachable" message. To use the pool summary feature, create a network-aligned pool and set the Pool Summary parameter to Yes.

To be network-aligned, the Pool Start address must be the first host address. Pool Start address -1 is used to determine the network address (the zero address on the subnet). To have a power of two size, the Pool Count value must be two less than a power of two; for example, 2, 6, 14, 30, 62, 126. The Pool Count value + 2 is used to create a netmask. For example, with this configuration:

                Pool Summary=Yes
                Pool#1 start=10.12.253.1
                Pool#1 count=126

The network alignment address is Pool Start address -1: 10.12.253.0 and the netmask is Pool Count +2 addresses: 255.255.255.128. The resulting address pool network is:

    10.12.253.0/25

Usage: Specify Yes or No. No is the default.

- Yes indicates that network summarization is in use. The Pool Count and Pool Start values must be set up as described above.

- No indicates that host routes will not be summarized.

Example: Pool Summary=Yes

Dependencies: The Pool Count and Pool Start values must be set up as described above.

Location: `Ethernet > Mod Config > WAN Options`

See Also: Pool #N start, Pool #N count

## Port

Description: Specifies whether the MAX traps AIM port state changes and sends traps-PDUs (Protocol Data Units) to the SNMP manager. For details on the events that cause the MAX to send a traps-PDU, see the Ascend Enterprise Traps MIB.

Usage: Specify Yes or No. No is the default.

- Yes means the MAX traps AIM port state changes and send traps-PDS to the SNMP manager.

- No means the MAX does not generate traps for port changes.

Example: Port=Yes

Location: `Ethernet > SNMP Traps`

## Port N/N Dual (N/N=1/2, 3/4, 5/6)

Description: Specifies whether the MAX pairs ports for dual-port or FT1-B&O calls on a Host/6 module. In a dual-port call, a codec performs inverse multiplexing on two channels so that a call can achieve twice the bandwidth of a single channel. Inverse multiplexing is a method of combining individually dialed channels into a single, higher-speed data stream.

The codec provides two ports, one for each channel. Two AIM ports on the MAX connect a dual-port call to the codec; these ports can be the V.35, RS-499, or X.21 ports on the MAX, and are called the primary port and the secondary port. Because the MAX places the two calls in tandem and clears the calls in tandem, it considers them a single call.

Usage: Specify Yes or No. No is the default.

- Yes pairs the specified ports for a dual-port call.

  Port 1/2 Dual pairs ports 1 and 2 for a dual-port call.

  Port 3/4 Dual pairs ports 3 and 4 for a dual-port call.

  Port 5/6 Dual pairs ports 5 and 6 for a dual-port call.

- No does not pair the ports.

Dependencies: For a dual-port call, the call type is 2-channel. For an FT1-B&O call, the call type is FT1-B&O.

Location: `Host/Dual (Host/6) > Mod Config`

## Port Name

Description: Specifies a name for the Port profile. This name replaces PortN Menu as a menu title. For example, if it is set to Ascend for AIM port #1, the menu called 21-000 Port1 Menu becomes 21-100 Ascend.

Usage: Specify the name. You can specify up to 16 alphanumeric characters.

Example: Port Name=Ascend

Location: `Host/Dual (Host/6) > PortN Menu > Port Config`

## Port Password

Description: Specifies the password for incoming AIM or BONDING calls. Authentication is used only if the calling unit has a password defined in the Call profile. If the Call profile in the calling unit does not have a password defined, the units connect without authentication even though the originating unit may have sent parameters. Note that the MAX only authenticates AIM and BONDING calls; dual-port calls are not authenticated.

Usage: Enter a password of nine characters or less.

Example: Port Password=Ascend

Location: `Host/Dual (or Host/6 > Port N Menu > Port Config`

See Also: Call Password

## PPP

Description: In the Answer profile, this enables incoming PPP (Point-to-Point Protocol) connections. PPP sessions are single-channel connections to any remote device running PPP software. In the Ethernet profile, this enables terminal server users to initiate a framed PPP session from the terminal-server command line interface.

Usage: Specify Yes or No. Yes is the default in the Answer profile. No is the default in the Ethernet profile.

- Yes in the Answer profile means the MAX accepts inbound PPP calls, provided that they meet all other connection criteria. No means it will not accept inbound PPP connections.

- Yes in the Ethernet profile enables terminal-server users to invoke a PPP session. No prevents them from initiating a PPP session.

Dependencies: In the Ethernet profile, this parameter does not apply if terminal services are disabled.

Location: `Ethernet > Answer > Encap, Ethernet > Mod Config > TServ Options`

See Also: TS Enabled

## PPP Delay

Description: Specifies the number of seconds the MAX waits for PPP packets before transitioning to terminal server mode. Note that this applies to incoming modem, V.110, or V.120 asynchronous calls.

Usage: Specify a number between 1 and 60. The default is 5 seconds.

Dependencies: This parameter does not apply if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

## PPP Direct

Description: Specifies whether to start PPP negotiation immediately after a user enters the PPP command in the terminal server interface, or to wait to receive a PPP packet from an application. (Some applications expect to receive a packet first.)

Usage: Specify Yes or No. No is the default.

- Yes means the MAX begins PPP/LCP negotiation immediately after a user enters PPP at the command line.

- No means the MAX waits to receive PPP packets from the remote peer.

Dependencies: This parameter does not apply if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: PPP, PPP Delay

## PPP Info

Description: Specifies what message is displayed when a terminal server user initiates a framed PPP session from the command line.

Usage: Specify one of the following values:

- None (the default) specifies that no message appears.

- Mode specifies that the banner reads:

      Entering PPP Mode

      IP address is <ipaddr >

      MTU is 1524

  <ipaddr > is the caller's IP address. The value 1524 is the default size of a link's Maximum Transfer Unit.

- Session specifies that the banner reads:

      Entering PPP Session

      IP address is <ipaddr >

      MTU is 1524

Dependencies: This parameter does not apply if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: TS Enabled

## PPTP Enabled

Description: Enables or disables PPTP (Point-to-Point Tunneling Protocol) functionality in the MAX. When PPTP is enabled, the MAX can bring up a PPTP tunnel with a PPTP Network Server (PNS) and respond to a request for a PPTP tunnel from a PNS. You must specify the IP address of the PNS in one or more of the Route Line parameters.

Usage: Specify Yes or No. No is the default.

- Yes enables PPTP, enabling the MAX to bring up a PPTP tunnel to a PNS or respond to a tunnel request.

- No disables PPTP.

See Also: Route Line n, Line n tunneling type

Location: `Ethernet > Mod Config > L2 Tunneling Options submenu`

## Preempt

Description: Specifies the number of idle seconds the MAX waits before using one of the channels of an idle link for a new call.

Usage: Specify a number between 0 and 65535. The MAX sets no time limit if you enter 0 (zero). The default setting is 60.

Location: `Ethernet > Answer > Session Options, Ethernet > Connections > Session Options`

See Also: Call Type

## Preference

Description: Specifies the preference value for a route. RIP is a distance-vector protocol, which uses a hop count to select the shortest route to a destination network. OSPF is a link- state protocol, which means that OSPF can take into account a variety of link conditions, such as the reliability or speed of the link, when determining the best path to a destination network. Because these two metrics are incompatible, the MAX supports route preferences.

When choosing which routes should be put in the routing table, the router first compares preference values, preferring the lower number. If the preference values are equal, then the router compares the metric field, using the route with the lower metric.

- Connected routes have a default preference of 0

- OSPF routes have a default preference of 10

- ICMP redirects have a default preference of 30

- RIP routes have a default preference of 100

- Static routes have a default preference of 100

- ATMP routes have a default preference of 100

Usage: Specify a number between 0 and 255. Zero is the default for connected routes (such as the Ethernet). The value of 255 means Do not use this route; this value is meaningful only for Connection profiles.

Location: `Ethernet > Connections > IP Options, Ethernet > Static Rtes`

## PRI # Type

Description: PRI # Type is used for outbound calls made by the MAX on PRI lines so that the switch can properly interpret the phone number dialed. Ask your PRI provider for details on when to use each of the following settings. This parameter specifies the TypeOfNumber field in the called party's information element.

Usage: Specify one of the following values:

- National (the default) specifies phone numbers within the U.S. (TypeOfNumber=2)

- Intl specifies phone numbers outside the U.S. (TypeOfNumber=1)

- Local specifies phone numbers within your Centrex group. (TypeOfNumber=4)

- Abbrev. specifies that the phone number is abbreviated. (TypeOfNumber=6)

- NetSpecific (currently not implemented) specifies that the network you are connected to understands the phone number (TypeOfNumber=3)

- Unknown specifies that the phone number is none of the above. (TypeOfNumber=0)

- Inherit (Dial Plan profile only) applies to calls placed by a device connected to a local T1 PRI line supplied by a Host/BRI module. If you choose this setting, the caller on the WAN requests the same TypeOfNumber as the caller on the local ISDN BRI line.

Dependencies: The value you specify for PRI # Type in the Dial Plan profile overrides the value of PRI # Type in the Call profile and Connection profile if you have enabled the unit's Dial Plan profiles.

Location: `Host/Dual (Host/6) > PortN Menu > Directory (Call profiles), Ethernet > Connections (Connection profiles), System > Dial Plan, Ethernet > Frame Relay, Ethernet > X.25`

See Also: NumPlanID, Call-by-Call, T1-PRI:PRI # Type (Line profiles), Modem:PRI# Type (System profile)

## Pri DNS

Description: Specifies the IP address of the primary domain name server. You can specify a primary and secondary name server of each type. The secondary server is accessed only if the primary one is inaccessible.

Usage: Specify the IP address of the primary domain name server. The default value is 0.0.0.0. Accept this default if you do not have a domain name server.

Example: Pri DNS=10.207.23.1

Location: `Ethernet > Mod Config > DNS`

See Also: Domain Name, Sec DNS

## Pri Num

Description: Specifies the primary add-on number for the ISDN BRI line. When the MAX receives a multichannel AIM, BONDING, or MP+ call, it reports the primary add-on number (Pri Num) and the secondary add-on number (Sec Num) to the calling party. The calling MAX can then add more channels. If you do not specify an add-on number and the calling MAX needs to add more channels, it redials the phone number it used to make the first connection. For example, suppose that 777-3330 is the primary number for line #1, and 777-3331 is the secondary number for line #1. Set Pri Num=30 and Sec Num=31. (See Ch N # (N=1-24, 1- 32)for more detail on add-on numbers.)

Usage: Specify a phone number with a limit of 24 characters, which can include the following characters: 1234567890()[]!z-*#|. The default is null.

Example: Pri Num=30

Location: `Net/BRI > Line Config > Line N`

See Also: Sec Num, Sub-Adr

## Priority

Description: Specifies the priority of this router with respect to the designated router and backup designated router elections under OSPF. When two routers attached to a network attempt to become the designated router, the one with the highest Priority value takes precedence. A router whose Priority is set to 0 (zero) is ineligible to become the designated router on the attached network.

Usage: Specify a number. The default value is 5.

Location: `Ethernet > Connections > OSPF Options, Ethernet > Mod Config > OSPF Options`

## Pri SPID

Description: Specifies the primary Service profile Identifier (SPID) for the ISDN BRI line. The SPIDs assigned to a BRI line operating in multipoint mode are numbers used at the central switch to identify services provisioned for your ISDN line. A SPID is derived from a telephone number and should be supplied by your carrier.

Note: Not all telephone companies include a suffix on their SPIDs. When receiving SPIDs from your telephone company, ask them to verify whether or not suffixes are included. The SPID formats described in the next sections have been agreed upon by most telephone companies.

For example, for an AT&T switch in multipoint mode, SPIDs have one of these formats:

01nnnnnnn0

01nnnnnnn00

In the AT&T SPID formats, nnnnnn is the 7-digit phone number (not including the area code). For example, if the phone number is 555-1212, the SPID will be 0155512120 or 01555121200.

For a Northern Telecom switch, SPIDs have one of these formats:

aaannnnnnnSS

aaannnnnnnSS00

In the Northern Telecom SPID formats, aaannnnnn is the 10-digit phone number (including the area code). SS is an optional suffix-if specified it is a one or two-digit number differentiating the channels. For example, if the phone numbers are 212-555-1212 and 212-555-1213, the SPIDs may be:

21255512121

21255512132

or:

212555121201

212555121302

or one of the above formats followed by 00 (for example, 21255512130200).

Usage: Specify up to 16 characters; you must limit those characters to numbers, hyphens, and parentheses. The default value is 0 (zero).

Location: `Net/BRI > Line Config > Line profile > Line N`

## Private

Description: Specifies whether the MAX will disclose the existence of this route when queried by RIP or another routing protocol. Private routes are used internally but are not advertised.

Usage: Specify Yes or No. No is the default.

- Yes makes the route private. The MAX does not advertise the route.

- No means the route is advertised via routing protocols.

Dependencies: This parameter does not apply if the IP routing is not enabled.

Location: `Ethernet > Connections > IP Options, Ethernet > Static Rtes`

See Also: LAN Adrs, Metric, RIP, Route IP

## Pri WINS

Description: Specifies the IP address of the primary Windows Internet Name Service (WINS) server.

Usage: Specify an IP address in dotted decimal notation. The default is 0.0.0.0.

Dependencies: Pri WINS applies only to Telnet and raw TCP connections running under the MAX unit's terminal server interface.

Location: `Ethernet > Mod Config > DNS`

See Also: Sec WINS

## Profile Reqd

Description: Specifies whether the MAX rejects incoming calls for which it could find no Connection profile and no entry on a remote authentication server. If you do not require a configured profile for all callers, the MAX builds a temporary profile for unknown callers. Many sites consider this a security breach.

Note: Setting Profile Reqd to Yes disables Guest access for ARA connections.

Usage: Specify Yes or No. No is the default.

- Yes means a configured profile is required for all callers.

- No means that if a configured profile is not found, the MAX builds a temporary profile for the unknown caller.

Dependencies: This parameter does not apply to terminal server calls.

Location: `Ethernet > Answer`

See Also: AppleTalk, Encaps, Recv Auth, Route IP

## Prompt

Description: Specifies the prompt the MAX displays during a terminal server session.

Usage: Specify a string containing up to 15 characters. The default is ascend%.

Dependencies: This parameter is not applicable if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: TS Enabled

## Prompt Format

Description: Determines whether you are able to use the multi-line format for the terminal server login prompt.

Usage: Specify Yes or No. No is the default.

- Yes causes the MAX to interpret carriage-return/line-feed and tab characters in the string specified as the Login Prompt.

- No means the MAX does not interpret the line feed/carriage return character or the tab character.

Example: Prompt Format=No

Dependencies: This parameter is not applicable if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: TS Enabled, Login Prompt

## Protocol

Description: In a filter of type IP, specifies the protocol number to which the MAX compares a packet's protocol number. f you specify a protocol number, the MAX compares it to the protocol number field in packets to match them to this filter. The default protocol number of zero matches all protocols. Common protocols are listed below, but protocol numbers are not limited to this list. For a complete list, see the section on Well-Known Port Numbers in RFC 1700, Assigned Numbers, by Reynolds, J. and Postel, J., October 1994.

- 1: ICMP

- 5: STREAM

- 8: EGP

- 6: TCP

- 9: Any private interior gateway protocol (such as Cisco's IGRP)

- 11: Network Voice Protocol

- 17: UDP

- 20: Host Monitoring Protocol

- 22: XNS IDP

- 27: Reliable Data Protocol

- 28: Internet Reliable Transport Protocol

- 29: ISO Transport Protocol Class 4

- 30: Bulk Data Transfer Protocol

- 61: Any Host Internal Protocol

- 89: OSPF

Usage: Specify the number of the protocol. You can enter a number between 0 and 255. The default setting is 0 (zero). When you accept the default, the MAX disregards the Protocol parameter when applying the filter.

Location: `Ethernet > Filters > Input filters > In filter N > IP, Ethernet > Filters > Output filters > Out filter N > IP`

## Proxy Mode

Description: Specifies under what conditions the MAX responds to ARP requests for remote devices that have been assigned an address dynamically. It responds to the ARP request with its own MAC address while bringing up the connection to the remote device. This feature is referred to as Proxy ARP.

Description: Specify one of the following values:

- Off (the default) disables proxy ARP.

- Always specifies that the MAX responds to an ARP request regardless of whether a connection to the remote site is up.

- Inactive specifies that the MAX responds to an ARP request only for a remote IP address specified in a Connection profile, and only if there is no connection to the remote site.

- Active specifies that the MAX responds to an ARP request only if a connection to the remote site is up, regardless of whether a Connection profile exists for the link.

Dependencies: This parameter does not apply if IP routing is not enabled.

Location: `Ethernet > Mod Config > Ether Options`

See Also: Net Adrs, Route IP

## Q

## Queue Depth

Description: The maximum number of unprocessed SNMP requests which the MAX saves. If SNMP requests arrive at a rate faster than they can be processed, then a backlog builds up. This parameter sets the maximum depth of the queue. If the queue fills, further packets destined for it are discarded.

Usage: Enter an integer value from 0 to 1024. If you enter 0, the MAX saves SNMP requests until it runs out of memory. 0 is the default.

Note: Setting Queue Depth to 0 is not recommended. An unlimited queue depth could result in an out-of-memory error on the MAX if it receives a flood of packets on its SNMP port.

Location: `Ethernet > Mod Config > SNMP options...`

See Also: Rip Queue Depth

## R

## R/W Comm Enable

Description: Enables and disables the use of SNMP set commands.

Usage: Press Enter to select Yes or No.

- Yes enables the use of SNMP set commands. To use a set command, you must know the SNMP read-write community string specified in the R/W Comm parameter.

- No disables the use of set commands.

Location: `Ethernet > Mod Config > SNMP Options

` See Also: R/W Comm, Read Comm

## R/W Comm

Description: Specifies a read/write SNMP community name. If an SNMP manager sends this community name, it can access the Get, Get-Next, and Set SNMP agents.

Usage: Specify the community name that the MAX will use for authenticating the SNMP management station for read-write access. You can enter letters and numbers, up to a limit of 16 characters. The default is Write.

Location: `Ethernet > Mod Config > SNMP Options`

See Also: Read Comm, R/W Comm Enable

## Rate Limit

Description: Specifies the rate at which the MAX accepts multicast packets from clients on this interface. It does not affect the MBONE interface.

Note: By default, the Rate Limit parameter is set to 100. This disables multicast forwarding on the interface. If multicast forwarding is enabled on the interface but the Rate Limit parameter is left at the default 100, he forwarder handles IGMP packets, but does not accept packets from clients or forward multicast packets from the MBONE router.

To begin forwarding multicast traffic on the interface, you must set the rate limit to a number less than 100. For example if you set it to 5, the MAX accepts a packet from multicast clients on the interface every 5 seconds. Any subsequent packets received in that 5-second window are discarded.

Usage: Specify a number lower than the default 100 to begin forwarding multicast traffic on the interface.

Example: Multicast Rate Limit=5

Dependencies: This parameter has no effect when applied to the MBONE interface.

Location: `Ethernet > Mod Config > Multicast`

See Also: Multicast Forwarding, Mbone Profile, Client, Multicast Rate Limit

## RD MgrN (N=1-5)

Description: Specifies up to five IP addresses of SNMP managers that have SNMP read permission. The MAX responds to SNMP get and get-next commands from these SNMP managers only.

Usage: Specify the IP address of a host running an SNMP manager. The default is 0.0.0.0.

Dependencies: The Security parameter must be set to Yes for the RD Mgr1-5 parameters to have any effect. If the Security parameter is set to Yes, only SNMP managers at the IP addresses you specify can execute the SNMP get and get-next commands.

Location: `Ethernet > Mod Config > SNMP Options`

See Also: Security, WR Mgr1-5

## Read Comm

Description: Specifies a read-only SNMP community name. If an SNMP manager sends this community name, it can access the Get and Get-Next SNMP agents.

Usage: Specify the community name that the MAX uses for authenticating the SNMP management station for read-only access. You can enter up to 16 alphanumeric characters. The default is Public.

Location: `Ethernet > Mod Config > SNMP Options`

See Also: R/W Comm, R/W Comm Enable

## Recv Auth

Description: Specifies the authentication protocol the MAX uses to receive and verify a password for an incoming PPP connection.

Usage: Specify one of the following values:

- None (the default) means the MAX does not use an authentication protocol to validate incoming calls.

- PAP indicates the Password Authentication Protocol.

  PAP provides a simple method for a host to establish its identity in a two-way handshake. Authentication takes place only upon initial link establishment, and does not use encryption. The remote device must support PAP.

- CHAP indicates the Challenge Handshake Authentication Protocol.

  CHAP is more secure than PAP. It provides a way to periodically verify the identity of a host using a three-way handshake and encryption. Authentication takes place upon initial link establishment; the MAX can repeat the authentication process any time after the connection is made. The remote device must support CHAP.

- MS-CHAP means the connection must use Microsoft's extension of CHAP.

  MS-CHAP was designed mostly for Windows NT/Lan Manager platforms. For details, see ftp://ftp.microsoft.com/DEVELOPR/RFC/chapexts.txt.)

- Either specifies any of the supported authentication schemes.

  When you select Either, the MAX allows authentication if the remote peer can authenticate using any of the designated authentication schemes.

Dependencies: If you specify an authentication method, you must also specify a password in the caller's profile. For a nailed connection, you must set Recv Auth and Send Auth to the same value at both ends of the connection.

Location: `Ethernet > Answer > PPP Options`

See Also: Auth Host, Recv PW, Send Auth, Send PW

## Recv PW

Description: Specifies the password that the MAX expects to receive from the far-end while the connection is being authenticated. If this password is not sent by the far-end device, authentication fails. For PPP links, the password can contain up to 20 characters. For X.25/ PAD, it can contain 48 characters.

If the link uses Combinet bridging, and the Answer profile requires a Combinet password, specify a password using all lowercase letters.

Usage: Specify a password. The password is case sensitive. The default is null.

Dependencies: This parameter does not apply if Recv Auth is set to None.

Location: `Ethernet > Connections > Encaps Options, Ethernet > Names / Passwords`

See Also: Encaps, Password Reqd, Recv Auth, Send Auth, Send PW

## Remote Conf

Description: Specifies whether or not a RADIUS server remotely configures the login banner and a list of Telnet hosts for the terminal-server menu mode.

Usage: Specify Yes or No. No is the default.

- Yes means the MAX obtains the configuration for these items from RADIUS. The local configuration for these items is ignored.

- No means it uses the local configuration for these items.

Location: `Ethernet > Mod Config > TServ Options

` See Also: Banner, Host # Addr, Host # Text, Upd Rem Cfg

## Remote Mgmt

Description: Specifies whether the operator at the far end of an AIM call can manage the MAX remotely using the DO Beg/End Rem Mgm command. In remote management, the MAX uses bandwidth between sites over the management subchannel established by the AIM protocol. If remote management is disabled and the remote operator attempts to invoke that DO command, the message "Remote Management Denied" is displayed.

Usage: Specify Yes or No. Yes is the default.

- Yes allows remote management of the MAX unit via AIM call.

- No prevents remote management.

Dependencies: This parameter applies only when Call Type is set to AIM, FT1-B&O, or FT1- AIM. It does not apply if Call Mgm=Static.

## Reply Enabled

Description: Specifies whether the MAX processes DHCP packets and acts as a DHCP server on this connection.

Usage: Specify Yes or No. No is the default.

- Yes specifies that the MAX will process DHCP packets.

  If the connection to the MAX is over a bridged connection the MAX will respond to all DHCP requests. If the connection is over any other type of connection, the MAX will only respond to NAT (Network Address Translation) DHCP packets.

- No specifies that the MAX will not process DHCP packets; it routes or bridges DHCP packets as any other packet.

Location: `Ethernet > Answer > DHCP options, Ethernet > Connections > DHCP options

`

## Retransmit Interval

Description: Specifies the number of seconds between retransmissions of OSPF packets. OSPF uses this value for LSA transmissions and when retransmitting Database Description and Link State Request Packets.

Usage: Specify a number greater than zero. The default is 5.

Example: Retransmit Interval=15

Location: `Ethernet > Connections > OSPF Options, Ethernet > Mod Config > OSPF Options`

## Retry limit

Description: Specifies the number of times in a row, per connection, that the PAD allows the DTE to send a frame or frame acknowledgment in error before it disconnects the call. For a dial-up connection, the Retry Limit specifies how many times the PAD will allow the DTE to try to establish a call that fails because the X.25 virtual call to the host could not be established. When the DTE exceeds the Retry Limit, the PAD disconnects the call.

Usage: Specify a value between 1 and 15. The default is 3.

Dependencies: This parameter is always applicable.

Location: `Ethernet>Connections>any Connection profile>Encaps options
Ethernet > Answer > T3POS options`

## Reverse Charge

Description: Specifies whether the call packet should include a reverse charge request facility parameter.

Usage: Specify one of the following values:

- Yes

  Specifies that the call packet includes a reverse charge request facility parameter.

- No (the default)

  Specifies that the call packet does not include a reverse charge request facility parameter.

Dependencies: This parameter is always applicable.

Location: `Ethernet > Connections > any Connection profile > Encaps options
Ethernet > Answer > T3POS options`

## RIP

Description: Specifies how the MAX handles RIP update packets on the interface.

Note: Ascend recommends that all routers and hosts run RIP-v2 instead of RIP-v1. The IETF has voted to move RIP version 1 into the historic category and its use is no longer recommended.

Usage: Specify one of the following values:

- Off specifies that the MAX does not transmit or receive RIP updates. Off is the default.

- Recv-v2 indicates that the MAX receives RIP-v2 updates on the interface but does not send RIP updates.

- Send-v2

  This setting indicates that the MAX sends RIP-v2 updates on the interface but does not receive RIP updates.

- Both-v2 means the MAX sends and receives RIP-v2 updates on the interface.

- Recv-v1 indicates that the MAX receives RIP-v1 updates on the interface but does not send RIP updates.

- Send-v1

  This setting indicates that the MAX sends RIP-v1 updates on the interface but does not receive RIP updates.

- Both-v1 means the MAX sends and receives RIP-v1 updates on the interface.

Dependencies: This parameter does not apply if the MAX does not route IP.

Location: `Ethernet > Answer > Session Options, Ethernet > Connections > IP Options, Ethernet > Mod Config > Ether Options`

See Also: Route IP

## RipASEType

Description: Specifies how RIP routes are propagated into OSPF.

Usage: Specify one of the following values:

- Type1 is a metric expressed in the same units as the link-state metric (the same units as interface cost).

- Type2 is considered larger than any link-state path.

  Type 2 is the default. It assumes that routing between autonomous systems is the major cost of routing a packet, and eliminates the need for conversion of external costs to internal link-state metrics.

Dependencies: This parameter does not apply if the MAX does not route OSPF.

Location: `Ethernet > Mod Config > Route Pref`

## RIP Policy

Description: Specifies a split horizon or poison reverse policy to handle update packets that include routes that were received on the same interface on which the update is sent. Split- horizon means that the MAX does not propagate routes back to the subnet from which they were received. Poison-reverse means that it propagates routes back to the subnet from which they were received with a metric of 16.

Usage: Specify Split Hrzn or Poison Rvrs. Poison Rvrs is the default.

Example: RIP Policy=Poison Rvrs

Dependencies: This parameter does not apply to RIP-v2. It applies only to RIP-v1 packets.

Location: `Ethernet > Mod Config`

## Rip Preference

Description: Specifies the preference value for routes learned from the RIP protocol.

When choosing which routes to put in the routing table, the router first compares the Rip Preference values, preferring the lower number. If the Rip Preference values are equal, the router compares the Metric values, using the route with the lower Metric.

Usage: Specify a number between 0 and 255. The default value is 100. Zero is the default for connected routes (such as the Ethernet). The value of 255 means Do not use this route.

Dependencies: These are the default values for other types of routes:

- Routes learned from OSPF=10

- Routes learned from ICMP Redirects=30

- Static routes from IP address pools, RADIUS authentication, and the terminal server iproute add command=100

- Static routes in an IP Route profile or Connection profile=100

Location: `Ethernet > Mod Config > Route Pref

`

## Rip Queue Depth

Description: The maximum number of unprocessed RIP requests which the MAX saves. If RIP requests arrive at a rate faster than they can be processed, then a backlog builds up. This parameter sets the maximum depth of the queue. If the queue fills, further packets destined for it are discarded. This limit applies to each RIP socket, so if RIP is running on multiple interfaces, this parameter limits the number of requests stored per interface.

Usage: Enter an integer value from 0 to 1024. If you enter 0, the MAX saves RIP requests until it runs out of memory. 50 is the default.

Note: Setting Queue Depth to 0 is not recommended. An unlimited queue depth could result in an out-of-memory error on the MAX if it receives a flood of packets on its RIP port.

Dependencies: This parameter does not apply if the MAX does not listen to RIP updates.

Location: `Ethernet > Mod Config > Route Pref...`

See Also: Queue Depth, RIP

## RIP Summary

Description: Specifies whether to summarize subnet information when advertising routes. If the MAX summarizes RIP routes, it advertises a route to all the subnets in a network of the same class; for example, the route to 200.5.8.13/28 (a class C address) would be advertised as a route to 200.5.8.0. When the MAX does not summarize information, it advertises each route in its routing table "as-is;" in our example, the MAX advertises a route only to 200.5.8.13.

Usage: Specify Yes or No. Yes is the default.

- Yes causes the MAX to summarize RIP-v1 subnet information.

- No means the MAX advertises each route as-is.

Dependencies: This parameter does not apply to RIP-v2. It applies only to RIP-v1 packets. In addition, note that RIP Summary does not affect host routes.

Location: `Ethernet > Mod Config`

## Rip Tag

Description: Assigns a specific tag to all routes propagated from RIP into OSPF. A tag is a 32-bit hexadecimal number border routers can use to filter this record.

Usage: Specify a 32-bit hexadecimal number. The default is c0000000.

Dependencies: This parameter does not apply if the MAX does not route OSPF.

Location: `Ethernet > Mod Config > Route Pref`

## Rlogin

Description: Specifies whether an Rlogin session can be invoked from the terminal-server command line.

Usage: Specify Yes or No. No is the default.

- Yes enables Rlogin sessions.

- No means terminal-server users cannot invoke Rlogin.

Example: Rlogin=Yes

Dependencies: This parameter does not apply if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: TS Enabled

## Rob Ctl

Description: Specifies the robbed-bit call control mechanism that the MAX uses for inband signaling or a PBX that is not of type Leased 1:1. For inband signaling, the MAX places and answers calls using the call control mechanism you specify.

For PBX T1 conversion, the MAX emulates the WAN switch, and the PBX places and answers calls using the call control mechanism you specify.

Note: The call control mechanisms are based on the AT&T Special Access Connections specification for ACCUNET T1.5 services (AT&T TR 41458). Regardless of the type of call control mechanism you specify, the switch should not forward dialed digits to the MAX; doing so disrupts the handshaking process during multichannel calls.

Usage: Specify one of the following values:

- Wink-Start (the default) means the calling device goes off-hook and waits for a 200 msec wink before dialing.

  In a wink, the answering device transmits an off-hook signal for a few hundred milliseconds. After receiving the wink, the calling device begins dialing. Neither device sends a wink before answering a call.

- Idle-Start means neither device sends a wink before either dialing or answering, and that off-hook dialing alone initiates a call.

- Inc-W-400 means each device sends a 400 msec wink before dialing or answering a call. This is the appropriate setting when a MAX is connected back-to-back with another MAX, or when it is connecting to a PBX.

- Inc-W-200 means each device sends a 200 msec wink before dialing or answering a call.

- Loop-Start means the MAX uses loop start signaling instead of wink signaling.

  If you specify this setting, only MP+ and PPP provide an indication of call establishment or call termination. Using this setting for other types of calls is strongly discouraged. Specify it only if you cannot get wink signaling on your T1 access line.

  Loop-Start is not available when for PBX T1 conversion.

## Route AppleTalk

Description: This parameter enables or disables the routing of AppleTalk data packets on the interface. AppleTalk routing must be set on both sides of the connection, and the parameter in the AppleTalk options submenu for the profile.

Usage: Specify Yes or No. No is the default.

- Yes enables AppleTalk routing.

- No means the MAX will not route AppleTalk for this connection (if set in the Connection profile) or accept inbound AppleTalk routing calls (if set in the Answer profile).

Location: `Ethernet > Answer > PPP Options, Ethernet > Connections

` See Also: Net Start, Net End, AppleTalk, AppleTalk Router, Route AppleTalk, Zone Name

## Route IP

Description: Enables or disables the routing of IP data packets on the interface. IP routing must be enabled on both sides of the connection, and the MAX unit must be configured with an IP address in the Ethernet profile. To establish an inbound connection, IP routing must also be enabled in the Answer profile.

Usage: Specify Yes or No. Yes is the default.

- Yes enables IP routing.

- No means the MAX will not route IP for this connection (if set in the Connection profile) or accept inbound IP routing calls (if set in the Answer profile).

Dependencies: If you have a MAX running Multiband Simulation, Route IP is disabled.

Location: `Ethernet > Answer > PPP Option, Ethernet > Connections`

See Also: Bridge, Encaps, Profile Reqd

## Route IPX

Description: This parameter enables or disables the routing of IPX data packets on the interface. IPX routing must be enabled on both sides of the connection, and the MAX unit must be configured with an IPX network address and frame type in the Ethernet profile. Note that the MAX will route and spoof only one IPX frame type. Other frame types will be bridged if bridging is enabled.

Usage: Specify Yes or No. No is the default.

- Yes enables IPX routing.

- No means the MAX will not route IPX for this connection (if set in the Connection profile) or accept inbound IPX routing calls (if set in the Answer profile).

Dependencies: If you have a MAX running Multiband Simulation, Route IPX is disabled.

Location: `Ethernet > Answer > PPP Options, Ethernet > Connections`

See Also: Bridge, IPX Frame, IPX Net

## Route line n

Description: Specifies the IP address of the L2TP Network Server (LNS) if you set Line n tunnel type to L2TP, or the IP address of the PPTP Network Server (PNS) if you set Line n tunnel type to PPTP.

Usage: Specify an IP address. The default is 0.0.0.0. If you accept the default, the MAX does not tunnel any call received on the WAN line specified in Line n tunnel type.

Example: Route Line 1=10.10.10.10

Dependencies: When configuring L2TP, Route line n applies only if you set L2TP Mode to LAC or Both. When configuring PPTP, Route line n applies only if you set PPTP Enabled to Yes. You must also set the corresponding Line n tunnel type parameter to PPTP or L2TP, as applicable.

Location: `Ethernet > Mod Config > L2 Tunneling Options`

See Also: L2TP Mode, PPTP Enabled, Line n tunnel type

## RPOA

Description: Specifies the set of Recognized Private Operating Agency (RPOA) user facilities to use in the next call request. The RPOA facilities provide the data network identification code for the requested initial RPOA transit network and is in the form of four decimal digits.

Usage: Specify the RPOA user facilities to use in the next call request. You can specify up to four digits. The default is null.

Dependencies: Encaps must be set to X25/PAD for RPOA to be applicable.

Location: `Ethernet > Connections > any Connection profile > Encaps options
Ethernet > Answer > PAD options
Ethernet > Answer > T3POS options`

## RS-366 Esc

Description: Specifies the escape character the MAX uses during RS-366 ext2 dialing or during X.21 ext2 dialing.

Usage: Specify an escape character. You can enter one of these characters:

    * # 5 6 7 9 0 00

The default is #.

Location: `Host/Dual (Host/6) > PortN Menu > Port Config

` See Also: Dial

## Run OSPF

Description: Enables or disables OSPF on the interface. When OSPF is active, the MAX sends update packets out on the interface. These packets set the correct link state for the interface and make sure that the local link-state database is an exact copy of the database maintained by other OSPF routers.

Usage: Specify Yes No. No is the default.

- Yes turns on OSPF routing on the interface. There is currently no spoofing for running active OSPF over dial-on-demand links, so periodic OSPF traffic will bring up the link almost continuously. OSPF is meant to run on nailed connections.

- No turns off OSPF on the interface.

Dependencies: If you have a MAX running Multiband Simulation, Run OSPF is disabled.

See Also: Ethernet > Connections > OSPF Options, Ethernet > Mod Config > OSPF Options

## S

## SAP HS Proxy

Description: This parameter specifies whether the MAX performs SAP Home Server Proxy.

Usage: Press Enter to cycle through the choices.

- Yes enables NetWare SAP Home Server Proxy.

- No disables NetWare SAP Home Server Proxy.

  No is the default.

Dependencies: The SAP HS Proxy parameter does not apply (SAP HS Proxy=N/A) if IPX routing is disabled (Route IPX=No).

Location: `Ethernet > Connections > Any Connection Profile > IPX Options`

## SAP HS Proxy Net#n (n=1-6)

Description: Specifies an IPX network to which SAP broadcasts should be directed.

Usage: Press Enter to open a text field. Then, type an IPX network number using an 8-digit (4-byte) hexadecimal value. The default is 00000000.

Dependencies: The SAP HS Proxy Net#n parameter does not apply (SAP HS Proxy Net#n=N/A) if either IPX routing is disabled (Route IPX=No) or if SAP Home Server Proxy is disabled (SAP HS Proxy=No).

Location: `Ethernet > Connections > Any Connection Profile > IPX Options`

## SAP Reply

Description: Enables or disables a home agent's ability to reply to the mobile node's IPX Nearest Server Query if the home agent knows about a server on the home network. It is used only when accessing this unit as a home agent.

Usage: Specify Yes or No. No is the default.

- Yes enables the MAX configured as ATMP home agent to reply to a mobile node's Nearest Server Query with the address of a server on the home network.

- No means the MAX will not respond to these queries from a mobile node.

Location: `Ethernet > Mod Config > ATMP Options

` See Also: ATMP Gateway, ATMP Mode

## Sealing Current

Description: Sealing Current allows you to enable sealing on the loop. Sealing refers to the ability of the IDSL card to send some current (40V) on the line when enabled. You typically use this feature to keeps the physical connection from corroding. This could occur if there is no activity on the line such as when there is no device connected on the other end.

Usage: Specify Yes to enable sealing. The default value is Off.

Dependencies: Note that the Sealing Current setting is not saved to the MAX permanent memory. This means that whenever you reboot the MAX, the Sealing Current parameter reverts to its default value of 0.

Location: `BRI/LT > Line Diag > line n`

## Sec DNS

Description: Specifies the IP address of the secondary domain name server. It will be accessed only if the primary DNS server is unavailable.

Usage: Specify the IP address of the secondary domain name server. The default is 0.0.0.0. Accept this default if you do not have a secondary domain name server.

Example: Sec DNS=200.207.23.1

Location: `Ethernet > Mod Config > DNS`

See Also: Domain Name, Pri DNS

## Sec Domain Name

Description: Specifies a secondary domain name that the MAX can search using DNS. The MAX performs DNS lookups in the domain configured in Domain Name first, and then in the domain configured in Sec Domain Name.

Usage: Specify a secondary domain name. You can enter up to 63 characters.

Example: Sec Domain Name=xyz.com

Location: `Ethernet > Mod Config > DNS`

See Also: Domain Name

## Sec History

Description: Specifies a number of seconds to use as the basis for calculating average line utilization (ALU). The ALU is used in calculating when to add or subtract bandwidth from a multi-channel call that supports dynamic bandwidth management.

The number of seconds you choose for the Sec History parameter depends on your device's traffic patterns. For example, if you want to average spikes with normal traffic flow, you may want the MAX to establish a longer historical time period. If, on the other hand, traffic patterns consist of many spikes that are short in duration, you may want to specify a shorter period of time; doing so assigns less weight to the short spikes.

If you specify a small value for the Sec History parameter, and increase the values of the Add Pers parameter and the Sub Pers parameter relative to the value of Sec History, the system becomes less responsive to quick spikes.

The easiest way to determine the proper values for Sec History, Add Pers, and Sub Pers is to observe usage patterns; if the system is not responsive enough, the value of Sec History is too high.

Usage: Specify a number between 1 and 300. The default value for MP+ calls is 15 seconds; the default value for dynamic AIM calls is 30 seconds.

Dependencies: This parameter applies only to multilink calls that support dynamic management.

Location: `Ethernet > Answer > PPP Options, Host/Dual (Host/6) > PortN Menu > Directory, Ethernet > Connections > Encaps Options`

## Sec Num

Description: Specifies the secondary add-on number for the Net BRI line. When the MAX receives a multichannel AIM, BONDING, or MP+ call, it reports the primary add-on number (Pri Num) and the secondary add-on number (Sec Num) to the calling party. The calling MAX can then add more channels. If you do not specify a add-on number and the calling MAX needs to add more channels, it redials the phone number it used to make the first connection. (See Ch N # (N=1-24, 1-32)for more detail on add-on numbers.)

Usage: Specify a phone number with a limit of 24 characters, which can include the following characters: 1234567890()[]!z-*#|. The default is null.

Dependencies: This parameter does not apply when Link Type = P-T-P (point-to-point mode).

Location: `Net/BRI > Line Config > Line N`

See Also: Pri Num, Sub-Adr

## Sec SPID

Description: Specifies the SPID (Service Profile Identifier) associated with the secondary phone number for the Net BRI line. The carrier supplies both the phone number and the associated SPID.

If the MAX uses only one channel of a multipoint ISDN BRI line and another device uses the other channel, you can choose to operate in single-terminal mode. Set one channel to unused, and enter only one SPID. The device sharing the line must enter the other assigned SPID.

Note: The MAX appends the value of the SPID with a TID if you are connected to a Northern Telecom switch running NI-1.

Usage: Specify up to 16 characters; you must limit those characters to numbers, hyphens, and parentheses. The default value is 0 (zero).

Dependencies: This parameter does not apply when the line is serviced by an AT&T switch in point-to-point mode.

Location: `Net/BRI > Line Config > Line N`

## SecurID DES Encryption

Description: Specifies whether the server uses standard DES or the native encryption provided by SecurID.

Usage: Specify Yes or No. No is the default.

- Yes means the server uses standard DES encryption.

- No means the server uses the native encryption provided by SecurID.

Dependencies: This parameter does not apply unless Auth specifies SECURID.

Location: `Ethernet > Mod Config > Auth`

See Also: Auth, SecurID Host Retries, SecurID NodeSecret

## SecurID Host Retries

Description: Specifies the number of times the MAX attempts to contact the SecurID host before timing out.

Usage: Specify an integer. The default value is 3.

Dependencies: This parameter does not apply unless Auth specifies SECURID.

Location: `Ethernet > Mod Config > Auth`

See Also: Auth, SecurID DES Encryption, SecurID NodeSecret

## SecurID NodeSecret

Description: On the first successful authentication attempt, the SecurID host informs the MAX of a secret value, theoretically only known to the MAX, to be used in subsequent interactions between the MAX and the SecurID host. This value appears in the SecurID NodeSecret parameter. The operator must have sufficient permissions in the active Security profile to view the value of this parameter.

Note: After the SecurID server sets the value of this parameter, if you later reset the parameter to null, you must reinitialize the interface to the MAX in the SecurID server by using the Client Edit menu selection in the ACE server's sdadmin utility. Then, the server sends a new NodeSecret at the next successful authentication.

Usage: The initial value must be null (the default). After the first SecurID authentication occurs, the value is set by the server.

Dependencies: This parameter does not apply unless Auth specifies SECURID.

Location: `Ethernet > Mod Config > Auth`

See Also: Auth, SecurID Host Retries, SecurID NodeSecret

## Security

Description: Enables or disables a kind of security, which differs depending on where the parameter appears.

Usage: Specify one of the following values:

For SNMP address security, the default is No.

- Yes means the MAX compares the source IP address of packets containing SNMP commands against a list of qualified IP addresses specified in the RD Mgr1-5 and WR Mgr1-5 parameters. (The MAX always checks the version and community strings before making source IP address comparisons. The Security parameter does not affect those checks.)

- No means the MAX does not compare IP addresses, so address-security is not used.

For SNMP traps, the default is No.

- Yes means the MAX will generate traps for Security events (such as failed login attempts) and send the trap-PDU to the SNMP manager.

- No means Security events will not generate traps.

For terminal-server security, the default is None.

- Full means users are prompted for a name and password upon initial login and when they switch between terminal mode and menu mode.

- Partial means they are prompted for a name and password only when entering terminal mode, not for menu mode.

- None means they are not prompted for a login name and password to enter the terminal-server interface.

## Sec WINS

Description: Specifies the IP address of the secondary NetBIOS server.

Usage: Specify an IP address. The default is 0.0.0.0.

Example: Sec WINS=10.2.3.4

Location: `Ethernet > Mod Config > DNS`

See Also: Pri WINS

## Send Auth

Description: Specifies the authentication protocol that the MAX uses to send a password to the far-end of a PPP connection.

Usage: Specify one of the following values:

- None (the default) means the MAX does not use an authentication protocol to validate incoming calls.

- PAP indicates the Password Authentication Protocol.

  PAP provides a simple method for a host to establish its identity in a two-way handshake. Authentication takes place only upon initial link establishment, and does not use encryption. The remote device must support PAP, and you must specify a password in the Send PW parameter.

- CHAP indicates the Challenge Handshake Authentication Protocol.

  CHAP is more secure than PAP. It provides a way to periodically verify the identity of a host using a three-way handshake and encryption. Authentication takes place upon initial link establishment; the MAX can repeat the authentication process any time after the connection is made. The remote device must support CHAP, and you must specify a password in the Send PW parameter.

- PAP-TOKEN is an extension of PAP authentication.

  In PAP-TOKEN, the user making outgoing calls from the MAX authenticates his or her identity by entering a password derived from a hardware device, such as a hand-held security card. The MAX prompts the user for this password, possibly along with a challenge key. The NAS (Network Access Server) obtains the challenge key from a security server that it accesses through RADIUS.

  If you specify PAP-TOKEN-CHAP, you must enter a password in the Aux Send PW parameter; this password must match the password in the RADIUS entry for authenticating the call. If you do not enter identical passwords in the Aux Send PW parameter and the RADIUS entry, the MAX cannot extend the MP+ call beyond a single channel.

- PAP-TOKEN-CHAP is PAP-TOKEN for the base channel with CHAP for subsequent channels.

  For multilink PPP calls where the answering unit requires security card authentication, PAP-TOKEN and PAP-TOKEN-CHAP begin identically when authenticating the first channel of an MP+ call. However, when the MAX adds additional channels to the MP+ call, PAP-TOKEN requires security-card authentication for each new channel, while PAP-TOKEN-CHAP uses CHAP authentication for all new channels. CHAP authentication works automatically, without the use of a hand-held security card.

- CACHE-TOKEN begins authentication using a hand-held security card, and fills a token cache set up for you on the RADIUS server.

  CHAP authenticates your subsequent calls without using your hand-held security card. After a period of time configured in your entry in the RADIUS users file, the token cache expires and the next call you place must again be authenticated using your hand-held security card.

  If you request CACHE-TOKEN, the Send PW parameter must match the Ascend-Receive-Secret attribute in the RADIUS entry that authenticated the call. If you do not enter identical passwords in the Send PW parameter and Ascend-Receive-Secret attribute, CACHE-TOKEN calls are rejected after initial access through hand-held security card authentication.

Dependencies: For a nailed connection, you must set Recv Auth and Send Auth to the same value at both ends of the connection. PAP-TOKEN and PAP-TOKEN-CHAP require configuration of a SAFEWORD or ACE entry in the NAS's RADIUS users file with the caller's name. See the MAX Security Supplement for details.

## Send Disc

Description: Specifies the number of seconds the MAX waits from the time a call is presented before it clears the call. The value selected must be less than the T310 timer value used by the switch servicing the MAX.

Usage: Press Enter to open a text field. Then, type the number of seconds the MAX should wait from the time a call is presented to it before it clears the call. The timer is cancelled if the MAX sends a ISDN Alerting message or ISDN Disconnect message or if the network switch sends an ISDN Disconnect message. You can specify a number from 0 to 60. 0 disables this parameter. 0 is the default.

Dependencies: Send Disc does not apply if the MAX does not support ISDN signalling.

Location: `Net/T1 > Line Config > Line N`

See Also: Timeout Busy

## Send PW

Description: Specifies the password that the MAX sends to the far-end while the connection is being authenticated. If this password is not received by the far-end device, authentication fails. If the link uses Combinet bridging and the far-end Answer profile specifies that a password is required (Password Reqd=Yes), you must enter a password using all lowercase letters.

Usage: Specify a password, up to 20 characters. The password is case sensitive. The default is null.

Dependencies: This parameter does not apply if Send Auth is set to None.

Location: `Ethernet > Connections > Encaps Options`

See Also: Encaps, Password Reqd, Recv Auth, Recv PW, Send Auth

## Serial

Description: Specifies an ISDN subaddress associated with the MAX unit's AIM ports. ISDN subaddressing is used for routing inbound calls to the appropriate destination in the MAX unit.

Usage: Specify a number between 0 and 99. The default is 0.

Location: `System > Sys Config`

See Also: Ans N#

## Server

Description: Enables or disables the on-board RADIUS server, or specifies the IP address of a BOOTP server, depending on where the parameter appears.

In the RADIUS Server submenu of the Ethernet profile, it enables or disables the on-board RADIUS server, which enables the MAX to appear as a server to some client requests.

In the BOOTP Relay submenu of the Ethernet profile, it specifies the IP address of a BOOTP server for handling BOOTP requests. If a server is on the same local-area network as the MAX, BOOTP requests from other networks are relayed to the server. If a server is on another network, BOOTP requests from clients on the same local-area network as the MAX are relayed to the remote server. If you specify two BOOTP servers, the MAX that relays the BOOTP request determines when each server is used. The order of the BOOTP servers in the BOOTP Relay menu does not necessarily determine which server is tried first.

Usage: To enable the on-board RADIUS server, specify Yes. The default setting is No.

To enable the MAX to communicate with a BOOTP server, specify the server's IP address. The default is 0.0.0.0.

Location: `Ethernet > Mod Config > RADIUS Server, Ethernet > Mod Config > BOOTP Relay`

See Also: Client #, Server Key, Server Port BOOTP Relay Enable

## Server Key #N (N=1-9)

Description: Specifies up to nine RADIUS server keys, shared with the RADIUS clients. It is used to validate the authenticator field on requests and generate the authenticator on responses. You should specify a key for each client address. For example:

- Client #1= 125.65.5.0/24
  Server Key #1=bob

- Client #2= 125.5.0.0/16
  Server Key #2=bob

## Server Name

Description: Specifies the name of a NetWare server. In an IPX Route profile, it is the server that will be reached via the specified route.

In an IPX SAP Filters profile, it is the name of a local or remote NetWare server. If the server is on the local network and this is an Output filter, Server Name specifies whether to include or exclude advertisements for this server in SAP response packets. If the server is on the remote IPX network and this is an Input filter, the Server Name parameter specifies whether to include or exclude this server in the MAX service table.

Usage: Specify a NetWare server name. In an IPX SAP filter, you can use the wildcard characters * and ? for partial name matches.

Dependencies: These parameters do not apply if IPX routing is not in use.

## Server Port

Description: This parameter indicates the UDP port number to use for the on-board RADIUS server.

Usage: Specify a number between 1 and 65535. The default is 1700. Although the value can match the port setting for RADIUS authentication or accounting, we recommend that you specify a different port.

Dependencies: This parameter does not apply if the on-board RADIUS server is disabled.

Location: `Ethernet > Mod Config > RADIUS Server`

See Also: Client #, Server, Server Key

## Server Type

Description: Specifies an SAP service type. SAP advertises services by a type number. For example, NetWare file servers are SAP Service type 0004. For complete information on SAP service types, refer to your Novell NetWare documentation.

In an IPX Route profile, specifies the type of service advertised by the server that will be reached via the specified route.

In an IPX SAP Filters profile, the Server Type parameter specifies whether to include or exclude advertisements for the specified service type in SAP response packets. In an Input filter, it specifies whether to include or exclude remote services of this type in the MAX service table.

Usage: Specify a a hexadecimal number that represents a valid SAP service type.

## Sess Timer

Description: When set for RADIUS accounting, this parameter sets the amount of time the MAX waits for a response to a RADIUS accounting request. You can set this parameter globally and for each connection. If it does not receive a response within that time, the MAX sends the accounting request to the next server's address (for example, server #2). If all RADIUS accounting servers are busy, the MAX stores the accounting request and tries again at a later time. It can queue up to 154 requests.

When set for RADIUS/LOGOUT authentication, Sess Timer specifies the interval at which session reports will be sent to the RADIUS/LOGOUT authentication server. For example, if you wish the MAX to send Session Events at one-minute (60-second) intervals, set Auth to RADIUS/LOGOUT and Sess Timer to 60.

Usage: When setting the timer for RADIUS accounting, specify a number from 1 to 10. The default value in the Ethernet profile is 0. The default in a Connection profile is 1.

When setting the timer for RADIUS/LOGOUT authentication, specify a number between 0 and 655353. The default is 0, which means that no Session Events will be sent.

Example: Sess Timer=10

Dependencies: For accounting, this parameter applies only to RADIUS-because TACACS+ uses TCP, it has its own timeout method. For authentication, it applies only to RADIUS/ LOGOUT.

Location: `Ethernet > Mod Config > Accounting, Ethernet > Mod Config > Auth`

See Also: Acct, Auth

## Session Key

Description: Specifies whether or not all new session entries are assigned a session key in RADIUS.

Usage: Specify Yes or No. No is the default.

- Yes means session keys will be assigned to all new session entries.

- No means session keys will not be assigned.

Example: Session Key=Yes

Dependencies: This parameter is not applicable if Server is set to No. See the Attributes parameter for information about specifying which attributes will be required for identification of a session.

Location: `Ethernet > Mod Config > RADIUS Server`

See Also: Attributes

## Shared Prof

Description: The MAX can force terminal server users to connect using unique profiles.The Shared Prof parameter in the Ethernet > Mod Config profile or in a Connection profile specifies:

- whether multiple users can share a single Connection profile or a single RADIUS user profile or

- whether a single user can have multiple sessions active

This parameter enables multiple incoming calls to share a local Connection profile or a RADIUS users file with Connection profile parameters. Sharing a profile cannot result in two IP addresses sharing the same interface, so this parameter is typically used to share profiles when the caller is assigned an IP address dynamically, which ensures that each caller is assigned a unique address.

Usage: Specify Yes or No. No is the default.

- Yes means the MAX will allow more than one caller to share the same profile, provided that no IP address conflicts will result.

- No means the MAX will not allow shared profiles.

Note: If Shared Prof is set to No and a user attempts to log in to the MAX terminal server with the same username and password as an already active session, the following message is displayed and the MAX disconnects the user: ***Account Already In Use

Dependencies: This parameter does not apply to Combinet links or connections that have hard-coded IP addresses. For the Ascend-Shared-Profile-Enable attribute to apply, you must disable shared profiles for the MAX as a whole with Ethernet > Mod Config > Shared Prof = No.

Location: `Ethernet > Mod Config, Ethernet > Connections > any profile`

## Sig Mode

Description: Specifies the type of signaling used on the T1 or E1 line.

Usage: In a Net/T1 profile, specify one of the following values:

- Inband (the default)

  In this type of signaling, the line uses 8 kbps of each 64-kbps channel for WAN synchronization and other signaling. The remaining 56 kbps handle the transmission of user data. Another term for inband signaling is robbed-bit signaling. Robbed-bit refers to the 8 kbps of each channel used for signaling. T1 lines containing one or more switched channels, and Switched-56 lines use inband signaling.

  If you specify inband signaling, you must specify a call control mechanism using the Rob Ctl parameter.

- ISDN

  In this type of signaling, the D channel handles WAN synchronization and other signaling, and the B channels carry the user data. Another term for ISDN D-channel signaling is out-of-band signaling. T1 PRI and Net BRI lines containing one or more switched channels use ISDN D-channel signaling.

- NFAS (Non-Facility Associated Signaling)

  NFAS is a special case of ISDN D-channel signaling. When you use NFAS, two or more T1 PRI lines use the same D channel, and you can add a backup D channel. NFAS is required for the Switched-1536 data service; because all 24 channels of the T1 PRI line carry user data, the D channel must be on another line.

- PBX T1 specifies that line #2 can access the WAN through line #1.

  When Sig Mode=PBX T1, the MAX emulates the WAN switch and the PBX connected to the line #2 port places and answers calls using the call control mechanism you specify for Rob Ctl. If you set Sig Mode=PBX T1, keep this additional information in mind:

  - If Line #2 uses inband signaling and line #1 uses ISDN D-channel signaling, set PBX Type=Voice or PBX Type=Data.

  - Any calls placed to a device connected to line #2 are switched to line #1 of the expansion module or to any line configured for ISDN-that is, to any line for which Sig Mode=ISDN.

  - If line #2 consists entirely of nailed-up and unused channels, and line #1 uses inband signaling, set PBX Type=Leased 1:1.

  - The MAX connects calls received on line #1 to the corresponding nailed-up channels of line #2, or handles them in the usual manner when the corresponding channel of line #2 is unused.

  - If PBX Type=Voice, the MAX switches only incoming voice calls to line #2.

  - If PBX Type=Data, the Ans # and Ans Service parameters determine which incoming calls on the T1 PRI line the MAX switches to line #2.

  - Line #2 typically connects to a PBX or other type of device that uses inband signaling; do not use line #2 for data calls.

Specify one of the following values on an E1 line:

- None indicates a leased line.

- ISDN signaling using the D channel. The 32nd channel of the E1 line must be designated as the D channel.

- DPNSS indicates that the interface supports DPNSS or DASS 2 signaling.

- R2 indicates R2 signaling.

- Metered indicates metered R2 signaling protocol, used in Brazil and South Africa.

- Chinese indicates a version of the R2 signaling protocol specified for use in China.

## Silent

Description: Suppresses status messages when interactive users establish a terminal-server connection.

Usage: Specify Yes or No. No is the default.

- Yes suppresses status messages upon connection of interactive terminal-server sessions.

- No sends all status messages.

Example: Silent=Yes

Dependencies: This parameter is not applicable when terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

## Single Answer

Description: Specifies whether the MAX completes the answering and routing of one call before answering and routing the next call.

Usage: Specify Yes or No. Yes is the default.

- Yes means the MAX will answer and route one call before answering and routing the next call. Yes is the default, and should be used if the MAX is not configured for dual-port calls, or if an incoming call is explicitly routed.

- No means the MAX will answer and route an incoming call immediately.

Example: Single Answer=Yes

## SLIP

Description: Specifies whether an SLIP (Serial Line IP) session can be invoked from the terminal-server command line.

Usage: Specify Yes or No. No is the default.

- Yes enables users to invoke SLIP sessions from the terminal-server.

- No disables this use of SLIP.

Dependencies: This parameter does not apply if terminal services are disabled.

Location: `Ethernet > Mod Config > TServ Options`

See Also: TS Enabled

## SLIP BOOTP

Description: Specifies whether or not the MAX responds to BOOTP within SLIP sessions. If a unit dials into the MAX unit's terminal server and runs SLIP, it can get an IP address through a BOOTP request. This IP address is taken from the MAX unit's IP address pool or by the Ascend-IP-Pool-Definition attribute in the RADIUS database.

Usage: Specify Yes or No. No is the default.

- Yes enables the MAX to respond to a BOOTP request from the calling unit during a SLIP session.

- No disables BOOTP for SLIP sessions.

Dependencies: This parameter does not apply if terminal services are disabled or if SLIP is set to No.

Location: `Ethernet > Mod Config > TServ Options`

See Also: Pool # Count, Pool # Start, TS Enabled

## SLIP Info

Description: Specifies the type of information the MAX reports to SLIP users.

Usage: Specify one of the following values:

- Basic (the default)

  Specifies that the MAX only reports the SLIP user's IP address and the Maximum Transmission Unit (MTU).

- Advanced

  Specifies that the MAX reports the SLIP user's IP address, the MTU, the Netmask, and the Gateway to SLIP users. Note that the gateway is the MAX unit's IP address.

Example: The MAX now reports the following information whenever a user connects:

    Entering SLIP Mode

    IP address is 192.1.1.1

    MTU is 1500

    Netmask: 255.255.255.0

    Gateway: 192.168.6.181

The Netmask label identifies the subnet mask the MAX is using. The Gateway label identifies the MAX unit's IP address.

Location: `Ethernet > Mod Config > TServ Options

` See Also: IP Gateway Addr Msg, IP Netmask Msg

## SNTP Enabled

Description: Enables or disables the MAX to use SNTP (Simple Network Time Protocol- RFC 1305) to set and maintain its system time by communicating with an SNTP server. SNTP must be enabled for the MAX to communicate using that protocol.

Usage: Specify Yes or No. No is the default.

- Yes enables the MAX to use an SNTP server to maintain its time.

- No disables SNTP.

Dependencies: If enable SNTP, you must specify at least one SNTP server address.

Location: `Ethernet > Mod Config > SNTP Server`

See Also: SNTP Host #N, Time Zone

## SNTP Host #N (N=1-3)

Description: Specifies the IP address of up to three SNTP servers. If the server specified by SNTP Host #1 is not active, the MAX sends its requests to SNTP Host #2. If that server is not active, the MAX sends its requests to SNTP Host #3.

Usage: Specify an IP address. The default is 0.0.0.0.

Dependencies: This parameter does not apply if SNTP is not enabled.

Location: `Ethernet > Mod Config > SNTP Server`

See Also: SNTP Enabled, Time Zone

## Socket

Description: Specifies a well-known socket number.

Usage: Specify the socket number for the server.

Example: Socket=0000

Dependencies: This parameter does not apply if the MAX does not route IPX.

Location: `Ethernet > IPX Routes`

See Also: Route IPX

## Source Addr

Description: Specifies an IP address. If specified, the MAX ignores packets from that source for monitoring purposes. If a Source Mask is also specified, the MAX uses the combined address and mask to ignore packets from the specified source.

Note: Heartbeat monitoring is optional. It is not required for multicast forwarding.

Usage: Specify an IP address.

Example: Source Addr=10.2.3.4

Dependencies: To set up heartbeat monitoring, you must configure several parameters that define what packets will be monitored, how often and for how long to poll for multicast packets, and the threshold for generating an alarm. These parameters do not apply if multicast forwarding is not in use.

Location: `Ethernet > Mod Config > Multicast`

See Also: HeartBeat Addr, Heartbeat Udp Port, Source Mask, HeartBeat Slot Time, HeartBeat Slot Count, Alarm Threshold

## Source Mask

Description: Specifies an IP netmask. If specified, the MAX uses the combined address and mask to ignore packets from the specified source for heartbeat monitoring purposes.

Note: Heartbeat monitoring is optional. It is not required for multicast forwarding.

Usage: Specify a netmask.

Example: Source Mask=255.255.255.248

Dependencies: To set up heartbeat monitoring, you must configure several parameters that define what packets will be monitored, how often and for how long to poll for multicast packets, and the threshold for generating an alarm. These parameters do not apply if multicast forwarding is not in use.

Location: `Ethernet > Mod Config > Multicast`

See Also: HeartBeat Addr, Heartbeat Udp Port, Source Addr, HeartBeat Slot Time, HeartBeat Slot Count, Alarm Threshold

## Src Adrs

Description: Specifies a source IP address. After this value has been modified by applying the specified Src Mask, it is compared to a packet's source address.

Usage: Specify a source IP address the MAX should use for comparison when filtering a packet. The zero address 0.0.0.0 is the default. If you accept the default, the MAX does not use the source address as a filtering criterion.

Example: Src Adrs=10.62.201.56

Dependencies: This parameter applies only to filters of type IP.

Location: `Ethernet > Filters > Input filters > In filter N > IP, Ethernet > Filters > Output filters > Out filter N > IP`

See Also: Src Mask

## Src Mask

Description: Specifies a mask to apply to the Src Adrs before comparing it to the source address in a packet. You can use it to mask out the host portion of an address, for example, or the host and subnet portion.

The MAX applies the mask to the address using a logical AND after the mask and address are both translated into binary format. The mask hides the portion of the address that appears behind each binary 0 (zero) in the mask. A mask of all zeros (the default) masks all bits, so all source addresses are matched. A mask of all ones (255.255.255.255) masks no bits, so the full source address to a single host is matched.

Usage: Specify the mask in dotted decimal format. The zero mask 0.0.0.0 is the default; this setting indicates that the MAX masks all bits. To specify a single source address, set Src Mask=255.255.255.255 and set Src Adrs to the IP address that the MAX uses for comparison.

Example: Src Mask=255.255.255.0

Dependencies: This parameter applies only to filters of type IP.

Location: `Ethernet > Filters > Input filters > In filter N > IP, Ethernet > Filters > Output filters > Out filter N > IP`

See Also: Src Adrs

## Src Port #

Description: Specifies a value to compare with the source port number in a packet. The default setting (zero) indicates that the MAX disregards the source port in this filter. Port 25 is reserved for SMTP; that socket is dedicated to receiving mail messages. Port 20 is reserved for FTP data messages, port 21 for FTP control sessions, and port 23 for telnet.

Note: The Src Port Cmp parameter specifies the type of comparison to be made.

Usage: Specify a number between 0 and 65535.

Example: Src Port #=25

Dependencies: This parameter applies only to filters of type IP.

Location: `Ethernet > Filters > Input filters > In filter N > IP, Ethernet > Filters > Output filters > Out filter N > IP`

See Also: Dst Port #, Dst Port Cmp, Src Port Cmp

## Src Port Cmp

Description: Specifies the type of comparison the MAX makes when filtering for source port numbers using the Src Port # parameter.

Usage: Specify one of the following values:

- None (the default) means the MAX does not compare source port numbers.

- Less means the comparison succeeds if the number is less than the value of Src Port #.

- Eql means the comparison succeeds if the number equals the value of Src Port #.

- Gtr means the comparison succeeds if the number is greater than the value of Src Port #.

- Neq means the comparison succeeds if the number is not equal to the value of Src Port #.

Location: `Ethernet > Filters > Input filters > In filter N > IP, Ethernet > Filters > Output filters > Out filter N > IP

` See Also: Src Port #

## Stacking Enabled

Description: Enables the MAX to communicate with other members of the same stack. A MAX can belong to only one stack. All members of the stack use the same stack name and UDP port. A MAX can support up to 40 stacked channels. That is, channels that originate on another MAX but are bundled with channels on the current MAX. The total number of channels in a stack is limited by the performance considerations of the network because stacking MAX units causes extra traffic on the Ethernet.

If the local network supports more than one MAX, you can stack them to enable inbound multilink PPP connections to distribute bandwidth across the multiple MAX units. The stacked units must all have access to the same authentication information, typically on a RADIUS server. Every member of a stack must reside on the same physical LAN. A MAX unit can only belong to a single stack, but does not have to belong to any stack. Multiple stacks may exist on the same LAN by simply having different stack names.

Usage: Specify Yes or No. No is the default.

- Yes enables stacks in this MAX.

- No disables stacks in this MAX.

Location: `Ethernet > Mod Config > Stack Options

` See Also: Stack Name, UDP Port

## Stack Name

Description: Specifies a stack name. Add a MAX to an existing stack by specifying that name. The stack name must be unique among all MAX stacks that may communicate with each other. You can create a new stack by specifying an new stack name.

Usage: Specify the name of the Stack to which this MAX belongs. A stack name must 16 characters or less.

Example: Stack Name=Stack-1

Dependencies: This parameter does not apply if stacks are not enabled.

Location: `Ethernet > Mod Config > Stack Options`

See Also: Stacking Enabled, UDP Port

## Static Preference

Description: Specifies the default preference value for statically configured routes.

Usage: Specify a number between 0 and 255. The default value is 100. Zero is the default for connected routes (such as the Ethernet). The value of 255 means Don't use this route.

Example: Static Preference=100

Dependencies: These are the default route preference values:

- Routes learned from OSPF=10

- Routes learned from ICMP Redirects=30

- Routes learned from RIP=100

- Static routes in an IP Route profile or Connection profile=100

Location: `Ethernet > Mod Config > Route Pref

`

## Station

Description: Specifies the name of the far-end device in this Connection profile. If the connection uses Combinet encapsulation, it is the MAC address of the far-end Combinet bridge.

Note: If this Connection profile specifies a nailed link to the home network for a MAX acting as an ATMP home agent in gateway mode, the Station name must match the Ascend-Home- Network-Name attribute in the foreign agent's RADIUS configuration.

Usage: Specify the name of the far-end device. You can enter up to 31 characters. Make sure you specify the name exactly, including case changes.

For a Combinet link, specify the 12-digit hexadecimal MAC address of the far-end device.

Example: Station=NewYork

Location: `Ethernet > Connections`

See Also: ATMP Mode, Type

## Status N (N=1-8)

Description: Enables you to customize the status windows in the vt100 interface so that particular screens appear at startup. The numbers 1 through 8 indicate the position of the status window, starting with the upper left. You can also use Ctrl-D-M to automatically configure the Status parameter.

Usage: Specify a window number in the format XY-NNN.

- X is the module number, and indicates a virtual or real module.

  A virtual module (0-2) reflects a function of the base system. Virtual module 0 manipulates overall system functions. Virtual module 1 is the Net/T1 module, which manipulates the base system's two-line T1 PRI network interface. Virtual module 2 is the Host/Dual module, which manipulates the base system's two AIM ports.

  A real module (3-8) plugs into an expansion slot in the MAX.

- Y is the port number.

  Zero indicates information pertinent to any portion of the module. A nonzero value indicates the AIM port to which the window applies. For system and T1 PRI network windows, the port number is always 0.

- The three digits after the dash are the root number.

  A root number of 000 identifies a top-level branch of the tree. If N is not 0 (zero), the root number identifies a window lower in the tree.

Example: Status 1=20-100

Location: `System > Sys Config`

## Sub-Adr

Description: Specifies how the MAX treats incoming calls based on whether they convey an ISDN subaddress.

Usage: Specify one of the following values:

- Termsel specifies that the MAX must use an ISDN subaddress to determine whether a call is answered.

  The called-party number must have a subaddress that matches a subaddress in the Line profile of the line on which the MAX receives the call. Otherwise, the MAX ignores the call. If the MAX accepts the call, the subaddress becomes part of the incoming phone number, and the MAX uses it in Ans # comparisons.

  This setting is intended for a scenario in which equipment is connected to a multidrop ISDN BRI line.

- Routing specifies that the called-party number may or may not have a subaddress.

  If a subaddress is present, it becomes part of the incoming phone number. The MAX matches it against the value of the Serial, LAN, DM, and V.110 parameters in the Sys Config menu in order to determine the interface to which it should route the call. If no match is found, the MAX uses the subaddress in Ans # comparisons.

- None specifies that the MAX does not use subaddressing.

Location: `System > Sys Config

` See Also: Ans #, DM, LAN, Serial, V.110

## Sub Pers

Description: Specifies a number of seconds for which the ALU (average link utilization) must persist below the Target Util threshold before the MAX subtracts bandwidth.

When utilization falls below the threshold for a period of time greater than the value of the Sub Pers parameter, the MAX attempts to remove the number of channels specified by the Dec Ch Count parameter. However, the MAX never subtracts enough bandwidth the clear the call or cause the channel count to fall below the specified minimum. Setting the Add Pers and Sub Pers parameters prevents the system from continually adding and subtracting bandwidth, and can slow down the process of allocating or removing bandwidth.

Add Pers and Sub Pers have little or no effect on a system with a high Sec History value. However, if the value of Sec History is low, the Add Pers and Sub Pers parameters provide an alternative way to ensure that spikes persist for a certain period of time before the system responds.

Usage: Specify a number between 1 and 300. When the MAX is using MP+, the default value is 10. When the MAX is using dynamic AIM, the default value is 20.

Example: Sub Pers=15

Location: `Ethernet > Answer > PPP Options, Host/Dual (Host/6) > PortN Menu > Directory, Ethernet > Connections > Encaps Options`

## T302 Timer

Description: This parameter specifies the duration of the ISDN Q.931 layer 3 SETUP_ACK timer.

When the MAX receives the layer 3 SETUP message, the SETUP message consists of many IEs (Information Elements), such as Bearer Capability IE, Channel Identifier IE, Caller Number IE, Called Number IE, Sending Complete IE, and so on. The MAX checks for the Sending Complete IE upon receiving the SETUP message from the switch. If the Sending Complete IE is not in the SETUP message, the MAX starts the T302 timer and waits for an INFO message from switch. If the INFO message consists of Sending Complete IE, MAX stops the T302 timer. If no Sending Complete IE appears, the MAX restarts the T302 timer.

Usage: You can specify a value between 100 and 30000 one-hundredths of a second (1 to 30 seconds). The default value is 1800 (18 seconds).

Dependencies: T302 Timer does not apply if T-Online=No.

## T3POS T2

Description: Specifies the SYN-to-SYN timer. This timer applies to opening frames in Local or Bin-Local mode. Normally, the PAD sends SYN signals to the DTE at the interval specified by the T2 timer to indicate that an idle link is still alive. However, if the DTE sends a SYN signal to the PAD before the PAD sends one to the DTE, the T2 timer specifies the period of time the PAD expects SYN signals from the DTE. If the PAD does not receive two SYN signals with the interval specified by the T2 timer, it tries to restore the link.

Usage: Specify a value between 10 and 100 (tenths of seconds). The default is 40.

Dependencies: Keep the following information in mind.

- The T2 timer only applies to the opening frame and to Local or Bin-Local mode.

`

## TCP Modem Port

Description: Specifies the port for TCP modem access.

Usage: Specify a TCP port. The default is 6150.

Location: `Ethernet > Mod Config > TCP Modem Options`

## TCP timeout

Description: Specifies the length of time the MAX attempts to connect to an IP host in the list provided by the DNS server.

Since the first host on the list may not be available, the timeout should be short enough to allow the MAX to go on to the next address on the list before the client software times out.

This feature applies to all TCP connections initiated from the MAX, including telnet, rlogin, tcp-clear, and the TCP portion of DNS queries.

Usage: Enter a value from 0 to 200. The value specifies the number of seconds after which the MAX will stop attempting to connect to an IP address and will proceed to the next address on the list.

When the MAX has sent the maximum number of messages to an address on the DNS list it will stop attempting to make a connection to that address, even if the maximum time set in DNS Timeout has not yet elapsed.

The default for DNS Timeout is 0. If you set TCP timeout to 0, the MAX retries connecting to the address at increasingly larger intervals until it sends the maximum number of start-connection messages. This takes approximately 170 seconds, but can take longer if the MAX is running large number of other tasks. If the client software times out before the MAX makes a connection or proceeds to the next address on the DNS list, the physical connection is dropped.

Dependencies: The List Attempt parameter in the DNS submenu of the Mod Config menu in the Ethernet Profile must be enabled. This permits the MAX to attempt the IP addresses. On a list, if the DNS server provides such a list. The List Attempt parameter does not apply if Telnet and Immediate Telnet are both disabled.

## Third-Party

Description: This enables OSPF third-party routing for a static route. When enabled, the gateway address is used as the third-party router for this route. Third-party routing enables an OSPF router to advertise a route to a destination network through a remote router (Router-A advertises a route to Network-B via Router-C). This is accomplished by specifying the address of the remote router (Router-C) in the next-hop field of an LSA.

Note: In some cases, third-party routing results in more efficient routes, because other OSPF routers (such as Router-D and Router-E) might be able to trim one hop off of the packet's path and send it to the specified address (Router-C) directly. In practice, it requires that the third- party router is on an Ethernet that is running OSPF, and that its designated router is advertising that network into the OSPF cloud.

Usage: Specify Yes or No. No is the default.

- Yes enables third-party routing for the OSPF router.

- No disables third-party routing.

Example: Third-Party=Yes

Dependencies: Third-Party does not apply to NSSAs.

## VCE Timer Val

Description: This sets the Virtual Call Establishment (VCE) timer by specifying the number of seconds to maintain a connection to a character-oriented device (such as a terminal server) that has not established a virtual call. This timer value is link-wide. Each X.25 PAD connection has a parameter to enable or disable this timer on a per-connection basis.

Usage: Specify a number of seconds between 0 and 9999. A value of 0 disables this timer system-wide regardless of the value of the VC timer enable flag per connection. The default is 300 seconds.

Location: `Ethernet > X.25`

See Also: VC Timer

## Version

Description: Specifies the version number of a Secure Access Firewall. Each firewall contains a version number to ensure that any firewall that is uploaded to the router will be compatible with the firewall software on the MAX. Secure Access Manager (SAM) checks the version number before uploading a firewall. In the event that an MAX with a stored firewall profile receives a code update that makes the existing firewall incompatible, a default firewall is enabled, permitting only Telnet access to the MAX.

Usage: This parameter cannot be edited.

Location: `Ethernet > Firewalls`

## VJ Comp

Description: Specifies whether Van Jacobson IP header compression should be negotiated on incoming calls using encapsulation protocols that support this feature. VJ Comp applies only to packets in TCP applications, such as Telnet. Turning on header compression is most effective in reducing overhead when the data portion of the packet is small.

Usage: Specify Yes or No.

- Yes enables VJ compression for TCP packets.

  This is the default.

- No disables VJ compression.

Location: `Ethernet > Answer > PPP Options, Ethernet > Connections > Encaps Options

`

## VPN Mode

Description: Specifies whether or not the MultiVoice Access Manager (specified by the IP address in the GK IP Adrs parameter) requires callers to authenticate by means of a PIN number.

Usage: Specify Yes or No.

- Yes enables VPN mode. The MultiVoice Access Manager does not require callers to authenticate by means of a PIN number.

  This is the default.

- No disables VPN mode. Every caller must authenticate by means of a PIN number, and to complete a call, the caller's PIN must match a PIN in the database of the MultiVoice Access Manager.

Dependencies: VPN Mode applies only if the MAX acts as a MultiVoice Gateway.

Location: `Ethernet > Mod Config > VOIP Options`

See Also: GK IP Adrs, Pkt Audio Mode

## W

## WAN Alias

Description: Specifies the IP address of the link's remote interface to the WAN. It is used to identify a numbered interface at the remote end of the link. If an address is specified for WAN alias, the following events occur:

- Host routes are created both to the Lan Adrs and the WAN Alias address. The WAN Alias will be listed in the routing table as a gateway (next hop) to the Lan Adrs.

- A route is created to the remote system's subnet, showing the WAN Alias as the next hop.

- Incoming PPP/MPP calls must report their IP addresses as the WAN Alias (rather than the Lan Adrs). That is, the caller must be using a numbered interface, and its interface address must agree with the WAN Alias on the receiving side.

If you want to create static routes to hosts at the remote end, you can use the WAN Alias address as the "next hop" (gateway) field. (The Lan Adrs address will also work, as would be used for system-based routing.)

Usage: Specify the IP address of the remote interface. The default is 0.0.0.0/0.

Example: WAN Alias=10.207.23.7/24

Dependencies: This parameter does not apply if the connection does not route IP.

Location: `Ethernet > Connections > IP Options`

See Also: Route IP, IF Adrs

## WR MgrN (N=1-5)

Description: Specify up to five IP addresses of SNMP managers that have SNMP write permission. The MAX responds to SNMP SET, GET, and GET-NEXT commands from these SNMP managers only, provided that the Security parameter is set to Yes.

Usage: Specify the IP address of a host running an SNMP manager. The default setting is 0.0.0.0; this setting indicates no host.

Example: WR Mgr1= 10.5.6.7/29

Dependencies: The Security parameter must be set to Yes for these parameters to restrict read-write access to the MAX.

Location: `Ethernet > Mod Config > SNMP Options`

See Also: Security, RD Mgr1-5

## X

## X.121 src addr

Description: Specifies the X.121 source address is the MAX unit's source address for logical links using this X.25 profile. An X.121 address contains between 1 and 15 decimal digits, such as 031344159782738.

Usage: Specify an X.121 address.

Example: X.121 src addr=031344159782738

Location: `Ethernet > X.25`

## X.25 Clear/Diag

Description: Specifies whether Clear-Request packets include the diagnostic field.

The DTE sends a Clear-Request packet to initiate clearing procedures for a call. The DCE accomplishes the same task by using a Clear-Indication packet. The DTE can send a Clear-Request packet to refuse an incoming call, or to clear a call once the data exchange is complete. Once the DTE or DCE receives a Clear-Confirmation packet, the call is cleared and the logical channel is available for other calls.

A Clear-Request packet has a required Cause field and an optional Diagnostic field. If the Cause field indicates that the remote DTE did not request the reset, the diagnostic field has standard values. If the Cause field indicates that the remote DTE requested the reset, the diagnostic field contains information specified in the Cause field by the remote DTE.

Usage: Specify Yes or No. No is the default.

- Yes causes the MAX to include the diagnostic field in Clear-Request packets.

- No means the optional diagnostic field is not included in Clear-Request packets.

Location: `Ethernet > X.25

` See Also: X.25 Reset/Diag, X.25 Restart/Diag

## X.25 highest PVC

Description: Specifies the highest Permanent Virtual Connection (PVC) number in a range defined by the X.25 lowest and X.25 highest PVC parameters. The range of PVCs can be between 1 and 4096. If the lowest PVC number is zero, no PVCs are supported.

Usage: Specify the high number in the range of PVCs available for this X.25 profile. The default is zero. The number you specify must be greater than or equal to the value specified by the X.25 lowest PVC parameter.

Description: Specifies the highest Switched Virtual Connection (SVC) number in a range defined by the X.25 lowest and X.25 highest SVC parameters. The range of SVCs can be between 1 and 4096. If the lowest SVC number is zero, no SVCs are supported.

Usage: Specify a number between 0 and 4095. The default is 8. The number you specify must be greater than or equal to the value specified by the X.25 Lowest SVC parameter.

Example: X.25 highest SVC=8

Dependencies: If X.25 lowest SVC is zero, no SVCs are supported regardless of this setting.

Location: `Ethernet > X.25`

See Also: X.25 lowest SVC

## X.25 Link Setup Mode

Description: Specifies whether the X.25 link comes up in active or passive disconnect mode. In ACTIVE disconnect mode (the default) the link layer comes up sending a DISC, and the packet layer sends a Restart-Request packet at initialization. In PASSIVE disconnect mode the link layer comes up sending SABM(E), and issues a restart to the network only upon receipt of a request restart token. It will not issue a Restart-Request packet upon initialization, but responds to restart packets it receives.

Usage: Specify one of the following values:

- ACTIVE specifies active disconnect mode. Active is the default.

- PASSIVE specifies passive disconnect mode.

Example: X.25 Link Setup Mode=ACTIVE

Location: `Ethernet > X.25`

## X.25 lowest PVC

Description: Specifies the lowest Permanent Virtual Connection (PVC) number in a range defined by the X.25 lowest and X.25 highest PVC parameters. The range of PVCs can be between 1 and 4096. If the lowest PVC number is zero, no PVCs are supported.

Usage: Specify a number between 0 and 4095. The default is 0 (zero), which means that no PVCs are available.

Example: X.25 lowest PVC=1

Dependencies: The upper limit of the range is defined by the X.25 highest PVC parameter.

Example: X.25 lowest SVC=1

Dependencies: The upper limit of the range is defined by the X.25 highest SVC parameter.

Location: `Ethernet > X.25`

See Also: X.25 highest SVC

## X.25 Max pkt size

Description: Specifies the maximum number of bytes in the data field of a data packet when negotiating the packet size with a remote X.25 switch. Note that a large packet size improves throughput by reducing the overhead associated with header transmission. However, a large packet size also increases the probability of transmission errors, causes increased transmission delays on the network, and is associated with processing delays at the host.

Usage: Specify one of the following values:

- 64

- 128 (the default)

- 256

- 512

- 1024

- 2048

Location: `Ethernet > X.25

` See Also: X.25 pkt size, X.25 Max pkt size, X.25 window size

## X.25 Network Type

Description: Specifies the type of network used by the link. At present, only the CCITT network type is supported.

Usage: CCITT specifies that the link uses a CCITT network. This is the only network type currently supported.

Example: X.25 Network Type=CCITT

Location: `Ethernet > X.25`

## X.25 Node Type

Description: Specifies whether the MAX interacts with the remote end of the connection as a DTE (the default) or DCE. A DTE is a device that an operator uses, such as a computer or a terminal. A DCE is a device that connects the DTE to a communications channel.

Usage: Specify one of the following values:

- DTE if the MAX interacts with the remote end of the X.25 connection as a DTE. This is the default.

- DCE if the MAX interacts with the remote end of the X.25 connection as a DCE

Example: X.25 Node Type=DTE

Dependencies: For proper X.25 operation, the two ends of a link must be of opposite types.

Location: `Ethernet > X.25`

## X.25 options

Description: Specifies X.25 packet-level options.

Usage: Specify one of the following values:

- None specifies that no packet-level options are enabled. None is the default.

` See Also: X.25 Max pkt size, X.25 Min pkt size, X.25 window size

## X.25 Prof

Description: Specifies the name of an X.25 profile to use for this connection. To guard against misconfiguration, the MAX does not allow you to save an active Connection profile specifying X.25 encapsulation unless the named X.25 profile is defined and active.

Usage: Specify the name of an X.25 profile, which can contain up to 15 characters.

Dependencies: This parameter applies only to X.25/PAD and X.25/IP connections.

Location: `Ethernet > Connections > Encaps Options`

## X.25 R20

Description: Determines the limit for Restart Retries-that is, the number of times the MAX transmits a Restart-Request packet before waiting indefinitely for a response. At the packet layer, a Restart-Request packet clears all virtual circuits. When the sending device receives a Restart-Confirmation packet, it can again issue a call to establish a virtual circuit.

Usage: Specify a number between 0 and 255. The default is 0 (zero). This default indicates that the MAX always waits indefinitely for a response.

Dependencies: The value you specify is not meaningful if X.25 T20=0.

Location: `Ethernet > X.25`

See Also: X.25 R22, X.25 R23, X.25 T20

## X.25 R22

Description: Determines the limit for Reset Retries-that is, the number of times the MAX retransmits a Reset-Request packet before clearing a call. At the packet layer, a Reset-Request packet resets the packet sequence number for the logical channel to 0 (zero), and removes any outstanding data and Interrupt packets from the virtual circuit. Once the sending device receives a Reset-Confirmation packet, it can send data on the logical channel.

Usage: Specify a number between 0 and 255. The default is 0 (zero).

Dependencies: The value you specify is not meaningful if X.25 T22=0.

Location: `Ethernet > X.25`

See Also: X.25 R20, X.25 R23, X.25 T22

## X.25 R23

Description: Determines the limit for Clear-Request Retries-that is, the number of times the MAX sends a Clear-Request before waiting indefinitely for a response.

The DTE can send a Clear-Request packet to refuse an incoming call, or to clear a call once the data exchange is complete. The DCE accomplishes the same task by using a Clear-Indication packet. Once the DTE or DCE receives a Clear-Confirmation packet, the call is cleared and the logical channel is available for other calls.

Usage: Specify a number between 0 and 255. The default is 0 (zero).

Dependencies: The value you specify is not meaningful if X.25 T23=0.

Location: `Ethernet > X.25`

See Also: X.25 R20, X.25 R22, X.25 T23

## X.25 Reset/Diag

Description: Specifies whether Reset-Request packets include the diagnostic field. At the packet layer, a Reset-Request packet resets the packet sequence number for the logical channel to 0 (zero), and removes any outstanding data and Interrupt packets from the virtual circuit. Once the sending device receives a Reset-Confirmation packet, it can send data on the logical channel.

A Reset-Request packet has a required Cause field and an optional Diagnostic field. If the Cause field indicates that the remote DTE did not request the reset, the diagnostic field has standard values. If the Cause field indicates that the remote DTE requested the reset, the diagnostic field contains information specified in the Cause field by the remote DTE.

Usage: Specify Yes or No. No is the default.

- Yes causes the MAX to include the diagnostic field in Reset-Request packets.

- No means the optional diagnostic field is not included in Reset-Request packets.

Description: Specifies whether Restart-Request packets include the diagnostic field. At the packet layer, a Restart-Request packet clears all virtual circuits. When the sending device receives a Restart-Confirmation packet, it can again issue a call to establish a virtual circuit.

A Restart-Request packet has a required Cause field and an optional Diagnostic field. If the Cause field indicates that the remote DTE did not request the restart, the diagnostic field has standard values. If the Cause field indicates that the remote DTE requested the restart, the diagnostic field contains information specified in the Cause field by the remote DTE.

Usage: Specify Yes or No. No is the default.

- Yes causes the MAX to include the diagnostic field in Restart-Request packets.

- No means the optional diagnostic field is not included in Restart-Request packets.

Location: `Ethernet > X.25

` See Also: X.25 Clear/Diag, X.25 Reset/Diag

## X.25 Seq Number Mode

Description: Specifies whether the MAX uses modulo 8 or modulo 128 sequence number mode. At the frame level, X.25 allows a sender to transmit a certain number of frames before requiring an acknowledgment of the first frame. The protocol increments a sequence number in the frame header, and places the value into the next outgoing frame. The sequence number identifies each frame that has not yet been acknowledged.

Usage: Specify one of the following values:

- NORMAL specifies modulo 8 mode.

  In modulo 8 mode, the sequence number can contain three bits, allowing eight frames to be identified with a single sequence number.

  Normal is the default.

- EXTENDED specifies module 128 mode.

  When substantial delays in transmission may occur, you can specify Extended so that the sequence number is enlarged to seven bits. When you choose this setting, 128 frames can be identified with a unique sequence number.

Example: X.25 Seq Number Mode=NORMAL

Location: `Ethernet > X.25`

## X.25 T20

Description: Determines the duration of the Restart timer-that is, the number of ten-second ticks the MAX waits before retransmitting a Restart-Request packet. At the packet layer, a Restart-Request packet clears all virtual circuits. When the sending device receives a Restart- Confirmation packet, it can again issue a call to establish a virtual circuit.

Usage: Specify a number between 0 and 255. The default is 0 (zero). This default setting disables the timer.

## X.25 T21

Description: Determines the duration of the Call-Request timer-that is, the number of ten- second ticks the MAX waits before clearing an outgoing call that has not been accepted. When a device makes an outgoing call, it sends a Call-Request packet. If the remote DTE accepts the call, it sends back a Call-Connected Packet; if the DTE refuses the call, it sends back a Clear- Request packet.

Usage: Specify a number between 0 and 255. The default is 0 (zero). This default setting disables the timer.

Location: `Ethernet > X.25`

See Also: X.25R21, X.25 T20, X.25 T22, X.25 T23

## X.25 T22

Description: Determines the duration of the Reset-Request timer-that is, the number of ten- second ticks the MAX waits before retransmitting a Reset-Request packet. At the packet layer, a Reset-Request packet resets the packet sequence number for the logical channel to 0 (zero), and removes any outstanding data and Interrupt packets from the virtual circuit. Once the sending device receives a Reset-Confirmation packet, it can send data on the logical channel.

Usage: Specify a number between 0 and 255. The default is 0 (zero). This default setting disables the timer.

## X.3 Custom

Description: This parameter specifies a string containing X.3 profile parameters. The Ascend unit parses this string into X.3 profile parameters when an operator uses the PAD.

Usage: Specify a string using this format:

    X.3 Custom=[ref:]val,[ref:]val, ... ,[ref:]val

where:

`ref` is the number of an X.3 parameter as defined in the ITU X.3 specification. You can specify a value between 1 and 22. By default, ref starts at 1 and is incremented by 1 after each comma. Unless you wish to specify fewer X.3 parameters than the maximum, you do not need to enter a value for ref.

`val` is the value associated with the X.3 parameter.

The Ascend unit silently ignores invalid parameters.

You can enter up to 64 characters for the entire X.3 Custom specification. By default, the X.3 Custom parameter contains the X.3 parameter values set in the CRT profile.

Dependencies: The X.3 Custom parameter does not apply if X.3 Param Prof is not set to CUSTOM.

Location: `Answer profile: Ethernet > Answer > X.25 Options
Connection profile: Ethernet > Connections > Any Connection profile > Encaps Options`

## Z

## Zone Name #n

Description: Specifies the name of the AppleTalk zone to which the MAX is connected. If the local Ethernet network supports an AppleTalk router with configured zones, you can place the MAX in one of those zones.

A zone is a multicast address containing an arbitrary subset of the AppleTalk nodes in an internet. Each node belongs to only one zone, but a particular extended network can contain nodes belonging to any number of zones. Zones provide departmental or other groupings of network entities that a user can easily understand. If the MAX is an AppleTalk router, it brings up the line when it receives packets addressed to the network number (defined by Net Start and Net End) or zone name specified for the remote connection, and routes packets to the appropriate network or zone.

Usage: Specify the name of a zone that has been configured on the local Ethernet network. Enter up to 33 alphanumeric characters.

If you do not specify a name and AppleTalk=Yes, the MAX acquires its zone(s) from the seed router on the network, including the default zone.

In an Ascend AppleTalk router, zone names are not case sensitive. However, some routers regard zone names as case sensitive, and you should be consistent in spelling zone names when you configure multiple connections or routers. Although AppleTalk permits the use of spaces in zone names, it does not consider an underscore to be the same as a space. Since some routers do equate the underscore and the space, or do not recognize a space as a valid character, it is advisable to use only the underscore in a network with routers other than Ascend routers.

Example: Default Zone=SALES
Zone Name #1=MKTG
Zone Name #2=ENGINEERING
Zone Name #3=ADMIN
Zone Name #4=BRANCH

Dependencies: If AppleTalk is disabled, the Zone Name parameter does not apply.
