Re: ISDN . Need Help

You may have to explain in more detail what you are trying to accomplish. The B-channels are "bundled" (multiplexed) together in a BRI and PRI configuration. There are installations where the S-bus (essentially the ISDN BRI) is shared, such that multiple boxes can "share" B-channels. However, many cisco devices do NOT support such a configuration (Hardware limitations); the MBRI on the 7200, 4xxx, 3600, 2600 does not support sharing the S-bus; the 100x, 1600, 2500, 7xx can. This type of config would also need to be coordinated with your carrier.

You need to use the dialer profiles..with two dialer interface..One going to each router.

Pl. visit here for a sample config.

Just add command "dialer max-call 1" under the each dialer interface to use one isdn b chan each.
