To scroll the selections in the Main Status Menu in a status window, Tab to the window, then use the Up Arrow or the Down Arrow key to scroll the window. To access a sub-menu, use the Right Arrow key, and to return to the original menu use the Left Arrow key.

Some of the status windows contain more information than can be displayed in the small window. A lowercase v in the lower-right corner of a window, indicates that more information is available. You can scroll through additional information if you make the window active.

Default status window displays

Line status windows

By default, the status of the lines in Slot 1 are shown in the top two status windows. For example:

|--------------------| |--------------------|
|10-100 1234567890   | |10-200 1234567890   |
| L1/LA nnnnnnnnnn   | | L2/RA ..........   |

|   nnnnnnnnnnnnnn   | |   ..............   |
|--------------------| l--------------------|

• The first line shows the menu number and column numbers for channels 1-10.

• The second line identifies the line (L1 or L2) , displays a a 2-character link-status indicator, and displays a 1-character channel-status indicator for each channel. For example:

  • LA indicates Link Active (the line is physically connected).

  • n means the channel is nailed.

  • * indicates a current connection.

  • - means the channels is idle but in service.

  • s means the channel is an active D channel (ISDN only).

• The third line has column headers for channels 11-24.

  The fourth line shows a 1-character channel-status indicator for channels 11-24.

|--------------------| |--------------------|

To display the Sessions window, tab to a status window, then use the arrow keys to access the Ethernet > Sessions window.

The system message log provides a log of up to 32 of the most recent system events. To display the System Message Log window, tab to a status window, then use the arrow keys to access the System > Message Log window.

Use an arrow key to scroll up (previous messages) or down (later messages). The Delete key clears all the messages in the log. The message log window is organized as follows:

• The first line shows the menu number and the time the most recently logged event occurred.

• The second line identifies the log entry number (M00-M31) and, if applicable, the line and channel on which the event occurred.

• The third line contains the text of the message. For example:

  • Call Terminated (An active call disconnected normally.)

  • LAN session up (An incoming connection has been established.)

  • No Connection (The remote device did not answer the call.)

• The fourth line contains a message qualifier, such as a name or phone number that qualifies the message displayed.

|--------------------| |--------------------|

The Ether Stat window shows the current count of received frames, transmitted frames, and frames with errors at the Ethernet interface. To display the Ether Stat window, tab to a status window, then use the arrow keys to access the Ethernet > Ether Stat window.

Sys Option and Main Status Menu windows

|--------------------| |--------------------|

|--------------------| |--------------------|

Up: 12:17:18:26

To display the System Options window, tab to a status window, then use the arrow keys to access the System > Sys Option window.

The last status window contains the Main Status Menu, a hierarchical menu that contains an entry for each line or installed card in the MAX. The structure of the Main Status Menu exactly follows the Main Edit Menu (the top-level configuration menu).

When the window that displays the Main Status Menu is active, the menu works like the Main Edit Menu. Use the arrow keys to scroll to a particular status menu. Then press the Enter key to open that menu and the Escape key to close it.

Specifying which status windows appear

To specify which status window appears on the VT100 interface, proceed as follows:

1. From the Main Edit Menu, select System > Sys Config.

2. Arrow-Down to the Status # parameter(s) of the status window(s) you would like to customize. For example, the MAX displays line-status windows for the T1 (or E1) lines in Slot 1 as windows 1 and 2 by default. Continue with the steps below to redefine the MAX to use status windows 3 and 4 to display line-status windows for the T1 (or E1) lines in Slot 2.

3. For the Status 3 parameter, specify the number identifying the status window menu it will be changed to.

   Note: Every menu and submenu has an identifying number, for example, 20-100, or 20-200. You can scroll through the Main Status Menu to get the identifying status numbers.

   Status 3=20-100
   

4. For the Status 4 parameter, specify the number identifying the status window menu it will be changed to.

   Status 4=20-200
   

5. Save and close the System profile.

   When the MAX resets, the status windows will appear with the new selections.

Status-window reference in alphabetic order

BRI/LT window

X0-000 BRI/LT
    XO-100 Line Status
    X0-200 Line Errors	
    X0-300 Block Errors
    X0-400 LB Counters
    X0-500 Net Options

The Line Errors status window displays the errors recorded on all current channels, in a channel-by-channel, line-by-line list. (For details, see "Line Errors window" on page 4-15.)

The Block Errors status window shows the errors for Near-End Block Errors (NEBE) and Far-End Block Errors (FEBE). The numbers displayed are totals accumulated since the last time the block error buffers were cleared. The FEBE and NEBE error buffers can be cleared per line and per counter. (You can clear the FEBE buffer for a line without clearing the NEBE buffer). The totals for each buffer reset to zero after they reach 65535. Restarting the MAX clears the buffers. For example, when a MAX with eight BRI lines is restarted, the Block Errors status window has the following contents:

X0-X00  FEBE      NEBE
  1:      0         0
  2:      0         0

  8:      0         0

Call Status window

A Call Status window exists for each host port. It is the first option listed in the PortN Stat window, and its window number is XN-100, where X is the module number and N is the AIM port number. For example:

71-000 Port1 Stat
>71-100 Call Status
 71-200 Message Log
 71-300 Statistics  
 71-400 Port Opts
 71-500 Session Err
 71-600 Port Leads

71-100 Albuquerque+ C
CALLING/ONLINE
336K      6 channels
 Albq. NM

The second line shows the call-status message corresponding to the current state. The message can change dynamically as you dial, modify, or receive calls. Table 4-1 lists the call status characters and messages that can appear:

Table 4-1. Call-status characters and messages

Status indicator	Status message	Description
Blank	IDLE	No calls exist and no other MAX operations are being performed.
A	ANSWERING	An incoming call is being answered.
R	RINGING	An incoming call is on the line, ready to be answered.
C	CALLING	An outgoing call is being dialed.
O	ONLINE	A call is up on the line.
Blank	/Online	Appended to another message to indicate that the MAX is currently adding or removing channels.
H	CLEARING	The current call is being cleared.
D	LOCAL LOOP	Local loopback diagnostic tests are in progress.
!	HANDSHAK	The MAX is exchanging information with the inverse multiplexer at the remote end and verifying the reliability of the transmission.
!	SETUP ADD	The MAX is preparing to add channels while a call is online and transmitting data.
!	SETUP REM	The MAX is preparing to remove channels while a call is online and transmitting data.
!	SETUP HND	The MAX is preparing to handshake for resynchronization while a call is online and transmitting data.
L	LOOP MAST	You have selected DO 6 or Control-D 6 to begin a remote loopback test. While the loopback test is in progress, the remote end displays the status message LOOP SLAV.
T	BERT MAST	The MAX has connected with the remote-end AIM-compatible product and is performing an automatic Byte Error Rate Test (BERT). Or, you are performing a manual BERT from the local MAX.
T	BERT SLAVE	Your MAX has received a call and the calling AIM-compatible product is performing an automatic BERT. Or, someone using the remote MAX is performing a manual BERT.

For calls other than FT1-B&O, the third line of the Call Status window shows both the current data rate in Kbps, and how many channels this data rate represents. If the current call type is FT1-B&O, the third line of the Call Status window shows how many channels the online data represents, followed by the number of nailed-up channels the MAX has placed offline because their quality was poor. For example, the following display shows the call status of an FT1-B&O call with six channels online and two channels offline:

21-100 Albuquerque+ C
CALLING
336K  6/2  channels
 Albq. NM

The last line of the Call Status window contains the name of the AIM port of the remote-end AIM-compatible product. If the remote-end Port profile is not named, the MAX uses the remote-end module name taken from the Host-Module profile. If neither the module nor the port is named, the MAX uses the remote-end system name.

Call Detail Reporting (CDR) window

You can arrange the information to create a wide variety of reports, which can be based on factors such as individual call costs, inverse-multiplexed WAN-session costs, costs on an application-by-application basis and bandwidth usage patterns over specified time periods. With the resulting better understanding of your bandwidth usage patterns, you can make any necessary adjustments to the ratio of switched to nailed bandwidth between network sites.

Like the MAX message logs, CDR shows the most recent session event. The MAX generates new CDR messages as events occur. However, unlike a log, the MAX does not store past CDR events. CDR is primarily a source of data captured by external devices.

To display the Call Detail Reporting (CDR) window, tab to a status window, then use the arrow keys to access the System > CDR window.

Following is a sample four-line CDR display:

00-400 CDR 
 93:05:28:10:33:52
 OR 025 384KR 02-01
 15105551212

The second line displays the time at which the event occurred, in the following format:

year:month:day:hour:minute:second

The third line displays the following items of information about the CDR event in the order shown:

Item	Description
CDR event description	Consists of one of the following abbreviations: OR-Originated (outgoing call) AN-Answered (incoming call) AP-Assigned to Port or module (incoming call) CL-Cleared OF-Overflowed All events except OF are associated with calls. OF indicates that the CDR buffer overflowed because events occurred faster than the MAX could report them.
CDR event ID	The MAX creates a new event ID for every DS0 channel originating a connection. The event ID ranges from 0 to 255. Events after 255 start the count again at 0. In addition, CDR creates a new event ID for every change in a channel's status. Because a MAX call can consist of several channels, the MAX can generate multiple CDRs for every change in call status.
Data service in use	Indicates the data service, using values nearly identical to those available to the Data Svc parameter in the Call profile. The only difference is that the Data Svc values 384K/H0 and 1536K correspond to the CDR data service values 384K and 1536KR, respectively.
Slot-port address	The address at which event occurred. For example, if the event occurred on the first port of a Host/6 card installed in slot 3, the slot-port address is 03-01.

The fourth line displays either the dialed or called-party phone number. If the event description on line 3 is OR (outgoing call), the number dialed appears. If the event description on line 3 is AN (incoming call), the called-party number appears. To get the called-party number on incoming calls, you must have DNIS service from your WAN provider. In some cases, the called-party number is not delivered, (for example, when the MAX is behind some types of PBX).

For related information, see the Data Svc parameter in the MAX Reference Guide.

Dyn Stat window (dynamic status)

Following is the Dyn Stat display for an Ethernet module in slot 9:

90-500 Dyn Stat
 Qual Good 00:02:03
 56K     1 channels
 CLU  12%  ALU  23%

The first line of the Dyn Stat window shows the window number and the name of the current Connection profile. If no connection is currently active, the window name appears instead.

The second line lists the quality of the link and the amount of time the link has been active. When a link is online more than 96 hours, the MAX reports the duration in number of days. The link quality can have one of the following values:

• Good-The current rate of CRC errors is less than 1%.

• Fair-The current rate of CRC errors is between 1% and 5%.

• Marg-The current rate of CRC errors is between 5% and 10%.

• Poor-The current rate of CRC errors is more than 10%.

• N/A-The link is not online.

The fourth line displays the following values:

• CLU-Current Line Utilization. The percentage of bandwidth currently being used by the call for transmitted data, divided by the total amount of bandwidth available.

• ALU-Average Line Utilization. ALU is the average amount of available bandwidth used by the call for transmitted data during the current history period as specified by the Sec History and Dyn Alg parameters.

Ether Opt window (Ethernet options)

Following is an example of an Ether Opt display for an Ethernet module in slot 9:

90-600 Ether Opt
>I/F: COAX
 Adrs: 00c07b322bd8

Ether Stat window (Ethernet status)

For example, the following screen shows the Ether Stat display for an Ethernet module in slot 9:

90-400 Ether Stat
>Rx Pkt:      106
    Col:        0
 Tx Pkt:      118

• Rx Pkt-the number of Ethernet frames received on the Ethernet interface

• Col-the number of collisions detected at the Ethernet interface

• Tx Pkt-the number of Ethernet frames transmitted over the Ethernet interface

Ethernet window

50-000 Ethernet
 50-100 Sessions
 50-200 Routes
 50-300 WAN Stat

The MAX has two windows that list the performance registers of the PRI interface: FDL1 Stats for line 1 and FDL2 Stats for line 2.

The FDL Stats windows are the fourth and fifth options listed in the Net/T1 window:

10-000 Net/T1
 10-300 Line Errors ^
 10-400 FDL1 Stats
>10-500 FDL2 Stats
 10-600 Net Options

10-500 FDL2 Stats
>Error Events...

 Last 24 Hours...
 00:00...          v

Error-register statistics

Performance-register statistics

If you have a D4 (SF) interface, no carrier performance data is recorded.

The performance registers contain both user and carrier Extended Superframe Format (ESF) statistics. The user performance-registers appear in the middle column after the register names, and the carrier performance-registers appear in the last column:

Use the Clr Perf1 and Clr Perf2 parameters in the Line Diag menu to reset the user performance registers but only the carrier can reset the carrier registers. All performance registers are reset upon power-up or software reset.

Table 4-2 describes the FDL performance registers.

Table 4-2. FDL performance registers

Register name	Description
EE	Displays the number of error events accumulated since the last time this register was reset. An ESF error event is counted when the CRC-6 calculations at the receiving end of the T1 span do not match the CRC-6 calculations at the sending end. This mismatch indicates that the frame had at least one data error. Error events have no meaning for D4 lines. Only ESF lines carry the CRC-6 signature used to check the quality of the PRI line as a whole.
ES	Specifies errored seconds. For ESF lines, this register displays the number of seconds in the 15-minute period in which there was at least one error event, or in which two or more framing errors were detected within a 3 ms interval. For D4 lines, this register displays the number of seconds in which one or more framing bit errors (FE) were detected or in which a controlled slip (CS) occurred.
US	Indicates unavailable seconds-the number of seconds in the 15-minute period preceded by at least 10 consecutive severely errored seconds (SS).
SS	Displays severely errored seconds-the number of seconds, during the 15-minute period, in which there were at least 320 CRC-6 errors as detected by the MAX, or in which the T1 line was out of frame. For D4 lines, this register displays the number of one-second intervals containing eight or more framing bit errors (FEs) or one or more SEFs.
BS	Specifies bursty errored seconds-the number of seconds, during the 15-minute period, in which there were at least 2, but not more than 319, CRC-6 errors as detected by the MAX.
LF	Indicates loss of frame seconds- the number of seconds in the 15-minute period in which the T1 line was out of frame.
CS	Displays controlled slip seconds-the number of seconds in the 15-minute period in which a frame was either replicated or deleted.

For related information, see Clr Err1, Clr Err 2, Clr Perf1, and Clr Perf2 in the MAX Reference Guide.

FR Stat window

For example, the following screen shows an FR profile display for a link using a serial WAN module is installed in slot B:

B0-500 FR profile
 Rx Pxt:       2560
 Tx Pxt:       3000
    CRC:        003
CprofX           16
 Rx Pxt:       2560
 Tx Pxt:       3000

Host/6 (Host/Dual) window

For example, the following screen shows a Host/Dual status window for a module installed in slot 6:

60-000 Host/Dual
 60-100 Host Config
 60-200 Port1 Menu
 60-300 Port2 Menu

To display the Line Errors window, tab to a status window, then use the arrow keys to select a menu item representing a slot configuration (this section assumes a slot configured for T1 lines). After selecting that item, select the Line errors window:

10-000 Net/T1
 10-100 Line 1 Stat
 10-200 Line 2 Stat
 10-300 Line Errors

10-300 Ln1  Ln2    
 1:      0    -
 3:     33    -
 4:      0    -    

The second column indicates the number of byte errors the MAX has detected on the channel in Line 1 during the current call. The third column displays the number of byte errors the MAX has detected on the channel in Line 2 during the current call.

If a channel is not associated with a current call, a hyphen (-) appears instead of a number. Any channel that would not have a number in either is omitted from the display.

Line Stat windows

For example:

10-100 1234567890

L1/LA   ----------

      12345678901234

      -------------s

The second line begins with the line number, followed by the link status, which is indicated by one of the two-character abbreviations listed in Table 4-3. Following the link status is followed by a single-character that indicates channel status. Table 4-4 lists the channel-status indicators.) The third line has column headers for the remaining channels. The fourth line continues where the second line left off, showing the status of the remaining channels.

Table 4-3. T1/E1 link-status indicators

Link status	Mnemonic	Description
LA	Link active	The line is active and physically connected.
RA	Red Alarm/Loss of Sync	The line is not connected, improperly configured, experiencing a very high error rate, or is not supplying adequate synchronization. The Alarm LED lights when the line is in this state.
YA	Yellow Alarm	The MAX is receiving a Yellow Alarm pattern. The Yellow Alarm pattern is sent to the MAX to indicate that the other end of the line cannot recognize the signals the MAX is transmitting. The Alarm LED lights when the line is in this state.
DF	D-channel failure	The D channel for a PRI line is not currently communicating.
1S	Keep alive (all ones). Also known as Blue Alarm.	A signal is being sent from the T1 PRI network to the MAX to indicate that the T1 PRI line is currently inoperative. The Alarm LED lights when the line is in this state.
DS	Disabled link	The line is physically connected, but you have disabled the line in the Line N profile.

A single character represents the status of each channel in the line, as described in Table 4-4:

Table 4-4. T1 channel status indicators

Channel status	Mnemonic	Description
.	Not available	The channel is not available because the line is disabled, has no physical link, or does not exist, or because the channel is set to Unused in the Ch N parameter of the Line N profile.
*	Current	The channel is connected in a current call.
-	Idle	The channel is currently idle (but in service).
d	Dialing	The MAX is dialing from this channel for an outgoing call.
r	Ringing	The channel is ringing for an incoming call.
m	Maintenance	The channel is in maintenance/backup (ISDN only).
n	Nailed	The channel is marked Nailed in the Line N profile.
x	Drop-and-Insert	The channel is configured for Drop-and-Insert for a DASS 2 E1 line or DPNSS E1 line.
o	Out of Service	The channel is out of service (ISDN only).
s	ISDN D channel	The channel is an active D channel (ISDN only).
b	Backup ISDN D channel	The channel is the backup D channel (ISDN only).

Line Status (BRI) window

For example, the following screen shows a Line Status window for a Net/BRI module installed in slot 4:

40-100 12345678    O
Link   PPP-----   
B1     ***.....     
B2     ***.....     

Table 4-5. BRI line-status indicators

The third and fourth lines indicate the state of the B1 and B2 channels, respectively, with the indicators shown in Table 4-6.

Table 4-6. B1 and B2 channel-status indicators

Channel status	Mnemonic	Description
.	Not available	The channel is not available because the line is disabled, has no physical link, or does not exist, or because the channel is set to Unused in the channel usage parameter of the Line N profile.
*	Current	The channel is connected in a current call.
-	Idle	The channel is currently idle (but in service).
d	Dialing	The MAX is dialing from this channel for an outgoing call.
r	Ringing	The channel is ringing for an incoming call.

Message Log windows

Each message log displays up to 32 of the most recent system events the MAX has recorded. When you select the Message Log option, the most recent message appears. The message logs update dynamically. Press the Up-Arrow key to display the previous entry. Press the Down Arrow key to display the next entry.

To display the Message Log window, tab to a status window, then use the arrow keys to access the Host/Dual > PortN Stat > Messages window.

Table 4-8 shows the warning messages that can appear in the Message Log windows.

Table 4-8. Warning log messages

Message	Description
Busy	The phone number was busy when the call was dialed.
Call Disconnected	The call has ended unexpectedly.
Call Refused	An incoming call could not be connected to the specified AIM port, digital modem, packet-handling module, or terminal server because the resource was busy or otherwise unavailable.
Dual Port req'd	The call could not be placed because one or both ports of the dual-port pair were not available.
Far End Hung Up	The remote end terminated the call normally.
Incoming Glare	The MAX could not place a call because it saw an incoming glare signal from the switch. Glare occurs when you attempt to place an outgoing call and answer an incoming call simultaneously. If you receive this error message, you have probably selected incorrect settings in the Line N profile.
Internal Error	Call setup failed because of a lack of system resources. If this type of error occurs, notify Ascend Customer Service.
LAN security error	Appears after Incoming Call but before Call Terminated if a PPP, MP+, terminal-server, or Combinet session has failed authentication, another session by the same name already exists, or the timeout period for RADIUS/TACACS authentication has been exceeded. For details, see the entry for the Auth Timeout parameter in the MAX Reference Guide.
Network Problem	The call setup was faulty because of problems within the WAN or in the Line N profile configuration. The D channel might be getting an error message from the switch, or the telco might be experiencing a problem.
No Chan Other End	No channel was available on the remote end to establish the call.
No Channel Avail	No channel was available to dial the initial call.
No Connection	The remote end did not answer when the call was dialed.
No Phone Number	No phone number exists in the Call profile being dialed.
No port DSO Mins	No MAXimum has been specified for the MAX DS0 Mins or MAX Call Mins parameter in the Port profile.
No System DSO Mins	No MAXimum has been specified for the MAX DS0 Mins parameter in the System profile.
Not Enough Chans	A request to dial multiple channels or to increase bandwidth could not be completed because there were not enough channels available.
Not FT1-B&O	The local MAX attempted to connect an FT1-B&O call to the remote end, but the call failed because the call type at the remote end was not FT1-B&O.
Remote Mgmt Denied	The MAX rejected a request to run the remote MAX by AIM remote management because the Remote Mgmt parameter in the System profile at the remote end is set to No.
Request Ignored	The MAX denied a request to manually change bandwidth during a call because the Call Mgm parameter in the Call profile is set to Dynamic. With this setting, the MAX allows only automatic bandwidth changes.
Wrong Sys Version	The remote-end product version was incompatible with the version of the local MAX. The software version appears on the Sys Options status window.

Table 4-9 shows connection messages that can appear on the fourth line of the Message Log windows.

Table 4-9. Message indicators

Indicator	Description
MBID value	Appears with either the Incoming Call or Assigned to Port (line 3) messages. The first message means an incoming call has been received and the second message means it has been routed to a MAX port. If you cannot match the MBID value of an incoming call log to the MBID value in an assigned-to-port log, the call disconnected, often because the intended port was busy. MBID also appears in the System log.
Channels	Number of channels added to or removed from a call. Appears with the Added Bandwidth, Removed Bandwidth, Moved to Primary, and Moved to Secondary messages. When line 3 is an Outgoing Call, line 4 displays the phone number dialed. In multichannel calls, line 4 displays the phone number for the first connection. Only the phone number appears. The parameter name, Phone Number, does not.
Cause Code	Indicates a signaling error or event. The code number was sent by the ISDN network equipment and received by the MAX.
Name	When the message in line 3 is either LAN session up or LAN session down, line 4 displays the remote end's name. If the session is a Combinet bridging link, the MAC address is displayed. If the session is a PPP link, either the remote end's system name (as specified by the Name parameter in the System profile) or IP address (as specified by the IP Adrs parameter in the Ethernet profile) is displayed. The IP address is displayed only if the system's name is not known.
CLID	When an incoming call is answered and the calling party number is known, line 4 specifies the calling line ID (CLID). When the CLID appears, the MBID does not.

Port Leads window

To display the Port Leads window for an AIM module, tab to a status window, then use the arrow keys to access the Host/Dual > PortN Stat > Port Leads window.

Following is an example of a Port Leads window for the serial WAN port:

B0-100 Port Leads  
 DSR+ DCD+ RI + DTR+

The first line of the window shows the slot-port address of the AIM port. The remaining lines show the state of the control leads going into and out of the serial port. A plus symbol (+) indicates an active control lead. A minus symbol (-) indicates that the lead is inactive. For RS-366 dialing output and input signals, the MAX uses the abbreviations in Table 4-12.

Table 4-12. RS-366 abbreviations

Output	Input
acr (Abandon Call and Retry)	dp (Digit Present)
pnd (Present Next Digit)	crq (Call Request)
dlo (Data Line Occupied)

If the port is an RS-366 dialing interface, the lower right-hand corner of the Post Leads window has a Digit field that displays the last digit dialed.

Table 4-13 lists the abbreviations for dialing output and input signals at the AIM port. The Clear to Send (CTS) output signal is not monitored in this window. The standard cables supplied with the MAX tie CD and CTS together.

Table 4-13. Serial host port abbreviations

Output	Input
DSR (Data Set Ready)	DTR (Data Terminal Ready)
CD (Carrier Detect)	RTS (Request to Send)
RI (Ring Indicate)

Table 4-14 lists the abbreviations used for dialing output and input signals at the serial WAN port.

A Routes window initially displays the first route in the table. For example:

50-200 Routes
>D: 223.0.100.129
 G: 223.0.100.129
 LOOP Active

The second line in a Routes window contains the destination address. The destination can be a network address or the address of a single station. If the route is the default route, the word Default replaces the address.

The third line shows the address of the router.

The fourth line can have one of the values listed in Table 4-16.

Table 4-16. Routes-window values

Value	Description
LAN Active	Active route. Has a destination on the local subnet.
WAN Active	Active route. Has a destination off the local subnet.
LOOP Active	Active route. Has this MAX as a router and destination. No data packets are propagated.
LAN Inactive	Inactive route. Has a destination on the local subnet.
WAN Inactive	Inactive route. Has a destination off the local subnet.

A route becomes inactive if taken out of service. Whether a dialed-up link in a route has or has not been connected does not affect the active or inactive status of the route

The second line lists the quality of the call and the call duration. When a call lasts more than 96 hours, the window displays the call duration in number of days. The call quality, or Qual, can be Good, Fair, Marg (marginal), or Poor. The meaning of each value is as follows:

• Good-No errors have been detected during the transmission of the call.

• Fair-Some errors have been detected in transmission.

• Marg-A significant number of errors have been detected. In this case, reliable transmission is not guaranteed and resynchronization is recommended.

• Poor-The MAX might drop individual channels from the call, or clear the call automatically.

21-300 Albuquerqu+ O
 Qual Good 00:04:01 
 MAX Rel Delay 10
 CLU  80%  ALU  77%

The last line displays the following values:

• CLU-Current line utilization. The percentage of bandwidth currently being used by the call for transmitted data, divided by the total amount of bandwidth that is available.

• ALU-Average line utilization. The average amount of available bandwidth used by the call for transmitted data during the current history period as specified by the Sec History and Dyn Alg parameters.

(For related information, see the Call Mgm, Call Type, Dyn Alg, and Sec History parameters in the MAX Reference Guide.)
