ISDN Backup to Frame-Relay

[brian]

I have a central location with a 2610XM with a frac t1 and a 4-port ISDN module. I have 4 remotes with 56K frame connections and I want to setup ISDN backup. I have read the "frame Relay Backup over ISDN paper" is there anything else out there that give a better description of how to backup at the DLCI level?

I should have indicated that I have 1600-R's at the remotes with WIC-1B-U modules.

There are many documents on ISDN backup of frame relay on www.cisco.com. There is also extensive coverage in my book High Availability Networking with Cisco, albeit not specifically addressing 1600-R as a platform. However, there are no significant differences (other than IOS bugs and interface designations, at least in theory) between different Cisco router platforms when it comes to ISDN backup of frame relay.

Good luck and have fun!
