3640 ISDN Dial-up Not Authenticating

On our 3640, normal modem users dial up and login, using a radius server, with no problem. We decided to allow ISDN users to also dial into the 3640. So far, my ISDN line makes a connection but never prompts me for a username and password in the Terminal Window as a normal modem would. We've also thought about changing the authentication for ISDN from the radius server to the 3640 locally. Any help would be appreciated.

Software Version 12.2(13)T3

Re: 3640 ISDN Dial-up Not Authenticating

You need to configure the 3640 for V.120 which allows virtual asynchronous data over ISDN bearer channels. Here is the url which has a sample config for that
