We are in the process of setting up a remote site. We are using BT to provide a point to point leased line and an ISDN30 PRI at both sites. Only 15 of the E1 channels will be enabled. We are using cisco 2800 routers with a single port serial wic card and a single port ISDN PRI network module in each. The PRI link is to be used as a backup in case of serial link failure I would appreciate detailed advice and guidance on the following:-
1) how to configure /enable the E1 controller (given that it is provided by BT and we are only using =BD of the channels)
2) How to set up the interfaces so that the router will automatically fail over to the PRI link
Thanks
