Hi. We have two T1s connecting point A and B. Each side has one router with two WIC Cards. All WIC cards are the same except for 1 which is a T1 controller [in a 3640]. We've tried MPPP as well as native EIGRP and static routes and CANNOT get one of the two circuits to stay live!! I am going to post the configs -- ANY help will be great. Both circuits WORK for about 5 minutes and then, the one with the controller goes dead... HELP.

I think the Cisco Systems' T1 data service unit/channel service unit (DSU/CSU) WAN interface card is an integrated, fully managed DSU/CSU for T1 or fractional T1 service. Supported on the Cisco 1600, 1720, 2600, 3600, and 3700 series routers. For more information please click following URL:
