Tips
If you have trouble:
• Be sure you have the correct ISDN switch type configured.
• Make sure no wires or cables are loose.
• The framing or line code types you entered might not match your telco’s settings. A Layer 2 error
indicates that the access server cannot communicate with the telco.
• Make sure the show controller t1 command’s current output shows no errors occurring.
Step 6—Configuring the Modems and Lines
Modems and lines are configured after the ISDN channels are operational, and voice calls are
successfully routed to the modems. Each modem is directly mapped to a dedicated async line in the
access server. After this configuration is set up, the access server is ready to take modem calls.
The modem speed 115200 bps and hardware flow control are the defaults for integrated modems.
Configure
To configure the modems and asynchronous lines, use the following commands beginning in global
configuration mode:
Step Command Purpose
1
hq-sanjose(config)# line 1 96
Enter the range of modem lines to configure.
In this example, the access server has 96 integrate modems.
2
hq-sanjose(config-line)# autoselect ppp
hq-sanjose(config-line)# autoselect during-login
Enable remote PPP users to dial in, bypass the EXEC facility,
and automatically launch PPP on the line.
1
Enter the autoselect during-login command to display the
username:password prompt after modems connect.
1. These two autoselect commands provide for transparent launching of shell and PPP services on the same lines.
3
hq-sanjose(config-line)# modem inout
Support incoming and outgoing modem calls.
