Where to go next

After installing the MAX hardware, you might want to perform a basic configuration so that you can test the setup. Procedures vary somewhat, depending on whether you use a T1 or an E1 configuration. (To perform a more advanced configuration, see the MAX 6000 Series Network Configuration Guide.)

Quickstart for T1 MAX units

Setting up your hardware

• One or more active and installed T1 lines accessible from the MAX. These lines must provide switched data service on at least two channels. For more information, see Provisioning the Switch.

• An active Ethernet LAN with appropriate cables and connectors.

• A remote unit (an Ascend unit or other compatible equipment) that you can Telnet to or Ping over a dial-up PPP encapsulated link across the WAN.

• A local host or workstation, on the same subnet as the MAX, that can Telnet to or Ping the MAX.

Figure 3-1. Quickstart setup

Overview of T1 line configuration

Inband signaling is less flexible than ISDN D-channel signaling, because you must preallocate the number of T1 channels used for voice calls and for data calls. If 12 analog callers are connected, subsequent analog callers are rejected because there are no more channels available for analog calls, even though there are 12 unused channels in the other hunt group.

Figure 3-2. Incoming call routing using inband signaling and hunt groups

With ISDN signaling, the hunt groups overlap the T1 channels, allowing each channel to answer either voice calls or data calls. Figure 3-3 illustrates the use of ISDN D-channel signaling. In this example, each hunt group includes all 24 channels. Analog callers call in to the phone number 555-1111 and are routed to the digital modems in slot 5. Digital callers call in using the phone number 555-2222 and are routed to the MAX bridge/router module in slot 9. To route the calls, you configure the Ans# parameter in both the Modem profile and the Ethernet Mod Config profile.

Incoming ISDN calls contain information about whether the call is an analog voice call (from a modem) or a digital data call. The MAX can automatically route voice calls to the digital modem card and digital calls to the bridge/router module.

Implementing a basic configuration

The Quickstart configuration involves modifying the following profiles:

Profile	Parameters that apply
Line N	One of the T1/PRI lines
Ethernet	The MAX unit's Ethernet address and protocols
Connection	Establishment of a WAN link and to the routing and bridging of data packets across the link
Answer	All incoming calls. The MAX uses the parameters in the Answer profile to determine what to do with incoming calls. Note that similar parameters that appear in Connection profiles take precedence over Answer profile parameters.

Configuring the T1/PRI lines

Specify signaling mode

1. From the Main Edit Menu, select the slot that contains your Net/T1 card (for example, 10-000).

   The slot's menu appears:

   10-000 Net/T1
       >10-100 Line Config
       10-200 Line Diag
   

2. Select Line Config.

   The Line Config menu appears:

   10-100 Line Config

       10-104 
   

3. Select the currently active slot profile, 10-1** Factory.

   The selected slot profile appears:

   10-1** Factory    
       >Name=
       1st Line=Trunk
       2nd Line=Disabled
       Line 1...
       Line 2...
   

4. Select Line 1.

   The Line 1 subprofile appears:

   10-1** Factory    
       Line 1...
           >Sig Mode=Inband  ^
             NFAS ID num=N/A
             Rob Ctl=Wink-Start
             Switch Type=N/A
             Framing Mode=D4
             Encoding=AMI
             FDL=N/A
             Length=N/A
             Buildout=0 dB 
             Clock Source=Yes
             Pbx Type=N/A
             Delete Digits=N/A
             Add Number=N/A
             Call-by-Call=N/A 
             Ans #=N/A     
   

5. Set the appropriate signaling mode for the Sig Mode parameter. The selections are:

   • ISDN

   • ISDN_NFAS

   • Inband

N/A (appropriate for Sig Mode=ISDN)
Wink-Start
Idle-Start
Inc-W-200
Inc-W-400
Loop-Start

If you selected ISDN, select the type of WAN switch used at the line's point-of-presence. The selections are:

N/A (appropriate for Sig Mode=Inband)
AT&T
NTI
NI-2
GloBanD
Japan

Continue specifying line parameters

1. Select the type of framing this line uses (D4 or ESF).

2. Set the encoding used on this line. The selections are:

   • None (identical to AMI, but without density enforcement)

   • AMI

   • B8ZS

3. Set the Facility Data Link (FDL) used on this line. The selections are:

   • N/A (appropriate for Framing Mode=D4)

   • None

   • AT&T

   • ANSI

   • Sprint

4. Specify the cable distance between the MAX and the WAN interface equipment.

   If the MAX has an internal CSU, select the N/A settings. Otherwise, select the correct cable distance in feet between MAX and the CSU or other network (WAN) interface unit to which it is connected. The default is 1-133.

5. Specify the amount of attenuation to add to the line's network interface.

   If the MAX does not have an internal CSU, select the N/A settings. Otherwise, select the Buildout value to provide the proper line attenuation. The default is 0dB.

6. If you cannot accept the default channel-type setting of switched for every channel on the line, set the Ch N parameter as required.

   • Switched (the default)

   • Nailed (dedicated)

   • Unused (not in service)

   Note: To test the line later, you must have at least two switched channels. If you plan to use a channel for drop-and-insert (D&I), you can enter it as Switched for the Quickstart and then change it to D&I for the final installation.

1. For each Ch N # parameter, enter the unique digits of the phone number used to reach this channel.

   For example, if your line is set up as illustrated in Figure 3-2 on page 3-2, enter 1111 for the first 12 channels, and 2222 for the last 12 channels.

2. For each T1 channel that will answer analog calls, set the Ch N Slot parameters to the number of the slot that contains the modem card.

   For example, if the modem card is in slot 5, set Ch 1 Slot=5, Ch 2 Slot=5, and so on, up to the total number of analog calls you want the MAX to accept on this T1 line. These settings tell the MAX to route incoming analog calls to the digital modem card.

3. For each T1 channel that will answer digital calls, set the Ch N Slot parameters to 9, the default number of the slot that contains the MAX unit's bridge/router module. These settings tell the MAX to route incoming digital calls to the bridge/router module, to be bridged or routed to their destination.

1. Press the Left-Arrow or Escape key to exit the Line 1 profile.

   • Send-v1-The MAX transmits RIP-v1 updates, but does not receive RIP updates.

   • Both-v1-The MAX transmits and receives RIP-v1 updates.

   • Send-v2- The MAX transmits RIP-v2 updates, but does not receive RIP updates.

   • Recv-v2-The MAX receives RIP-v2 updates, but does not transmit RIP updates.

   • Both-v2-The MAX transmits and receives RIP-v2 updates.

10. Press the Escape or Left-Arrow key until the confirmation menu appears, then press 2 to save your changes.

11. Press the Left-Arrow key until you return to the Main Edit Menu.

Testing the connections

• Test the LAN connection by using Ping or Telnet to reach the MAX from a workstation or host on the same LAN as the unit.

• Test the T1/PRI line by placing and answering a test call from the MAX to itself over the T1/PRI interface. This procedure tests the T1 lines to verify that they are active and that the phone numbers are correct.

• Test the WAN connection by using Ping or Telnet to reach a remote unit from a workstation or host on the same LAN as the MAX. This procedure also tests the processing of data packets through the MAX.

If you open a Telnet session with the MAX, the MAX user interface display should appear. If you have configured a Telnet password in the Ethernet > Mod Config > Telnet PW parameter, the MAX prompts for it before you can access the MAX user interface.

If you Ping the MAX, you should get a message saying that you are immediately receiving a return packet for every packet you are sending to the MAX. If you are not getting the proper response, the cause might be a problem with the LAN, entry of the wrong IP address, or misconfiguration of either the subnet mask or IP Adrs parameter in the Ethernet profile. If the host or workstation is on a different network than the MAX, make sure your IP routing configurations allow the host or workstation to reach the MAX.

Testing the T1/PRI line

The terminal-server Test command uses one channel to dial out and another channel to answer, as shown in Figure 3-6. Consequently, you must set the T1/PRI line for bidirectional calling and have two channels available for the test.

To perform the test:

1. From the Main Edit Menu, select System:

   The System menu appears:

   00-200 System
       00-100 Sys Config
       >00-200 Sys Diag
       00-300  Security
       00-400 Destinations
       00-500 Dial Plan
   

2. Select Sys Diag.

   The Sys Diag menu appears:

   00-200 Sys Diag    
       >00-201 Restore Cfg

4. Enter the Test command: test phone-number

   where phone-number is the phone number of the MAX T1 line.

   Note: The most frequent cause for failing to connect is an incorrect phone number.

5. If the test is unsuccessful, verify that you have entered all the T1 line parameters correctly and that your line is correctly provisioned as explained in Appendix A, Provisioning the Switch. If you cannot correct the problem, contact your carrier.

6. Enter the Quit command to exit the terminal-server interface.

7. Press the Left-Arrow or the Escape key to return to the Main Edit Menu.

• You can run Telnet or Ping from a host or workstation on the same LAN segment as MAX.

• There is a remote unit (MAX-compatible) to which you can route data packets over a dial-up link.

Figure 3-6. Testing the WAN by dialing into and out from the MAX

To test the WAN connection, proceed as follows:

1. Configure the routes of a host that is on the same LAN as your MAX so that your MAX is the gateway to the remote unit. The most common method is to add static routes.

   For example, if the remote unit address is 167.34.9.23, and the your MAX address is 165.3.45.8, the gateway configuration on the remote unit would be:

   • Address: 167.34.9.23

   • Gateway address: 165.3.45.8

     You can also make your MAX the default router.

2. From the local host, enter the Telnet or Ping command with an argument specifying the remote unit.

   If you use Telnet, and the remote unit's user interface display appears, the MAX is functioning properly and you are finished with this chapter.

   If you use Ping, and a message informs you that you are immediately receiving a return packet for every packet you are sending to the remote unit, the MAX is functioning properly and you are finished with the chapter.

   If you are not getting the proper response, the procedure has failed. The problem might be with the LAN or with your configuration. Verify the configuration of the Ethernet profile. You can also refer to the Troubleshooting chapter of the Administration Guide for your MAX.

3. Terminate the Telnet or Ping session.

Quickstart for E1 MAX units

Setting up your hardware for E1

• One or more active and installed E1 lines accessible from the MAX. These lines must provide switched data service on at least two channels. For more information, see Provisioning the Switch.

• An active Ethernet LAN with appropriate cables and connectors.

• A remote unit (an Ascend unit or other compatible equipment) that you can Telnet to or Ping over a dial-up PPP encapsulated link across the WAN.

• A local host or workstation, on the same subnet as the MAX, that can Telnet to or Ping the MAX.

Figure 3-7. Quickstart set up

Overview of E1 line configuration

R2 signaling is less flexible than ISDN D-channel signaling, because you must preallocate the number of E1 channels used for voice calls and for data calls. If 12 analog callers are connected, subsequent analog callers are rejected because there are no more channels available for analog calls, even though there are 12 unused channels in the other hunt group.

Figure 3-8. Incoming call routing using R2 signaling and hunt groups

With ISDN signaling, the hunt groups overlap the E1 channels, allowing each channel to answer either voice calls or data calls. Figure 3-9 illustrates the use of ISDN D-channel signaling. In this example, each hunt group includes all 24 channels. Analog callers call in to the phone number 555-1111 and are routed to the digital modems in slot 5. Digital callers call in using the phone number 555-2222 and are routed to the MAX bridge/router module in slot 9. To route the calls, you configure the Ans# parameter in both the Modem profile and the Ethernet Mod Config profile.

Incoming ISDN calls contain information about whether the call is an analog voice call (from a modem) or a digital data call. The MAX can automatically route voice calls to the digital modem card and digital calls to the bridge/router module.

Implementing a basic configuration

The Quickstart configuration involves modifying the following profiles:

Profile	Parameters that apply
Line N	One of the E1/PRI lines
Ethernet	The MAX unit's Ethernet address and protocols
Connection	Establishment of a WAN link and to the routing and bridging of data packets across the link
Answer	All incoming calls. The MAX uses the parameters in the Answer profile to determine what to do with incoming calls. Note that similar parameters that appear in Connection profiles take precedence over Answer profile parameters.

Configuring the E1/PRI lines

Specify signaling mode

1. From the Main Edit Menu, select the slot that contains your Net/E1 card (for example, 10-000).

   The slot's menu appears:

             NFAS ID num=N/A
             Rob Ctl=Wink-Start
             Switch Type=N/A
             Framing Mode=D4
             Encoding=AMI
             FDL=N/A
             Length=N/A
             Buildout=0 dB 
             Clock Source=Yes

Setting the remaining Line N parameters

1. Select the type of framing this line uses (G.703 or 2DS).

   Note: If you select G.703, the MAX provides CRC-4 checking. If you select 2DS, it does not.

2. Set the encoding used on this line: The selections are:

   • None: This is identical to AMI, but without density enforcement.

   • AMI

   • B8ZS

3. Set the Facility Data Link (FDL) used on this line. The selections are:

   • N/A (appropriate for Framing Mode=D4)

   • None

   • AT&T

   • ANSI

   • Sprint

4. Specify the cable distance between the MAX and the WAN interface equipment.

   If the MAX has an internal CSU, select the N/A settings. Otherwise, select the correct cable distance in feet between MAX and the CSU or other network (WAN) interface unit to which it is connected. The default is 1-133.

5. Specify the amount of attenuation to add to the line's network interface.

   If the MAX does not have an internal CSU, select the N/A settings. Otherwise, select the Buildout value to provide the proper line attenuation. The default is 0dB.

6. If you cannot accept the default channel-type setting of switched for every channel on the line, set the Ch N parameter as required.

   • Switched (the default)

   • Nailed (dedicated)

   • Unused (not in service)

   Note: To test the line later, you must have at least two switched channels. If you plan to use a channel for drop-and-insert (D&I), you can enter it as Switched for the Quickstart and then change it to D&I for the final installation.

1. For each Ch N # parameter, enter the unique digits of the phone number used to reach this channel.

   For example, if your line is set up as illustrated in Figure 3-8 on page 3-23, enter 1111 for the first 12 channels, and 2222 for the last 12 channels.

2. For each E1 channel that will answer analog calls, set the Ch N Slot parameters to the number of the slot that contains the modem card.

   For example, if the modem card is in slot 5, set Ch 1 Slot=5, Ch 2 Slot=5, and so on, up to the total number of analog calls you want the MAX to accept on this E1 line. These settings tell the MAX to route incoming analog calls to the digital modem card.

3. For each E1 channel that will answer digital calls, set the Ch N Slot parameters to 9, the default number of the slot that contains the MAX unit's bridge/router module. These settings tell the MAX to route incoming digital calls to the bridge/router module, to be bridged or routed to their destination.

   • Send-v1-The MAX transmits RIP-v1 updates, but does not receive RIP updates.

   • Both-v1-The MAX transmits and receives RIP-v1 updates.

   • Send-v2- The MAX transmits RIP-v2 updates, but does not receive RIP updates.

   • Recv-v2-The MAX receives RIP-v2 updates, but does not transmit RIP updates.

   • Both-v2-The MAX transmits and receives RIP-v2 updates.

10. Press the Escape or Left-Arrow key until the confirmation menu appears, then press 2 to save your changes.

11. Press the Left-Arrow key until you return to the Main Edit Menu.

Testing the connections

• Test the LAN connection by using Ping or Telnet to reach the MAX from a workstation or host on the same LAN as the unit.

• Test the E1/PRI line by placing and answering a test call from the MAX to itself over the E1/PRI interface. This procedure tests the E1 lines to verify that they are active and that the phone numbers are correct.

• Test the WAN connection by using Ping or Telnet to reach a remote unit from a workstation or host on the same LAN as the MAX. This procedure also tests the processing of data packets through the MAX.

If you open a Telnet session with the MAX, the MAX user interface display should appear. If you have configured a Telnet password in the Ethernet > Mod Config > Telnet PW parameter, the MAX prompts for it before you can access the MAX user interface.

If you Ping the MAX, you should get a message saying that you are immediately receiving a return packet for every packet you are sending to the MAX. If you are not getting the proper response, the cause might be a problem with the LAN, entry of the wrong IP address, or misconfiguration of either the subnet mask or IP Adrs parameter in the Ethernet profile. If the host or workstation is on a different network than the MAX, make sure your IP routing configurations allow the host or workstation to reach the MAX.

The terminal-server Test command uses one channel to dial out and another channel to answer, as shown in Figure 3-12. Consequently, you must set the E1/PRI line for bidirectional calling and have two channels available for the test.

To perform the test:

1. From the Main Edit Menu, select System:

   The System menu appears:

   00-200 System
       00-100 Sys Config
       >00-200 Sys Diag
       00-300  Security
       00-400 Destinations
       00-500 Dial Plan
   

2. Select Sys Diag.

   The Sys Diag menu appears:

   00-200 Sys Diag    
       >00-201 Restore Cfg 
       00-202 Save Config
       00-203 Use MIF
       00-204 Sys Reset
       00-205 Term Serv
       00-206 Upd Rem Cfg
   

3. Select Term Serv.

   The Terminal Server screen appears:

   ** Ascend Pipeline Terminal Server **

   ascend%  
   

4. Enter the Test command: test phone-number

   where phone-number is the phone number of the MAX T1 line.

   Note: The most frequent cause for failing to connect is an incorrect phone number.

5. If the test is unsuccessful, verify that you have entered all the T1 line parameters correctly and that your line is correctly provisioned as explained in Appendix A, Provisioning the Switch. If you cannot correct the problem, contact your carrier.

6. Enter the Quit command to exit the terminal-server interface.

7. Press the Left-Arrow or the Escape key to return to the Main Edit Menu.

• You can run Telnet or Ping from a host or workstation on the same LAN segment as MAX.

• There is a remote unit (MAX-compatible) to which you can route data packets over a dial-up link.

Figure 3-12. Testing the WAN by dialing into and out from the MAX

To test the WAN connection, proceed as follows:

1. Configure the routes of a host that is on the same LAN as your MAX so that your MAX is the gateway to the remote unit. The most common method is to add static routes.

   For example, if the remote unit address is 167.34.9.23, and the your MAX address is 165.3.45.8, the gateway configuration on the remote unit would be:

   • Address: 167.34.9.23

   • Gateway address: 165.3.45.8

     You can also make your MAX the default router.

2. From the local host, enter the Telnet or Ping command with an argument specifying the remote unit.

   If you use Telnet, and the remote unit's user interface display appears, the MAX is functioning properly and you are finished with this chapter.

   If you use Ping, and a message informs you that you are immediately receiving a return packet for every packet you are sending to the remote unit, the MAX is functioning properly and you are finished with the chapter.

   If you are not getting the proper response, the procedure has failed. The problem might be with the LAN or with your configuration. Verify the configuration of the Ethernet profile. You can also refer to the Troubleshooting chapter of the Administration Guide for your MAX.

3. Terminate the Telnet or Ping session.
