I am a programmer with a small company so I also have to wear the hat of systems admin, helpdesk, and network engineer. I know enough about networking to be dangerous so if you will take the time to answer please put it in simple language as I don't speak much network
I inherited a setup with 3 T1's from one provider (multilinked) all working well, and 2 T1's from another provider where only one of the circuits has ever worked. My mission is to get the second T1 from this provider working.
Things I think might be wrong but do not know how to determine as right or wrong are the hardware differences of the modules/carriages/whatever those boards are called that the csu/dsu's plug into as well as the csu/dsu's themselves seem to be different flavors.
The All of the T's on Serial0 work, the one on Serial1 does not. Also I am not using the Ethernet interfaces on the Serial1 either.
Pasting the inventory, config, and show interface results;
You're going to have to post the entire config, but in general because of t1 clock timing I don't think you want to mix controllers in the motherboard with controllers in the module slot of the router. The motherboard shares one timing clock and the slot module uses it's own. Also do some sh serial 1/0/0 service-module commands to see if you have a red alarm. If you do contact the carrier.
