Cisco to nortel isdn config

[jack57]

I need to config a Cisco 2600 router to use ISDN as a dial backup to a frame relay circuit. The Cisco will be dialing a Nortel BCN. Does anyone have a sample config that I can use. The Nortel is configured to accept specific chap info from the site. How do I include that in the Cisco config.

How you implement the ISDN backup is somewhat dependent what kind of routing (ie. dynamic or static) you can plan to implement as well.

Review the following URL. It breaks down the different kind of backup mechanisms available over ISDN and gives you some configs too.
