T-1 problem

[customcomm]

I have a modular ICS and it currently has a D4AMI T-1 on it with 200 DID #'s and loop start lines. They are switching providers and they want to switch to esf b8zs which is easy enough to change in programming but they are bringing it in aon a adtran and coming to me on the dsx1 port and it appears the switch likes the circiut but when I select a trunk it is silent then comes up and says not in service. The provider says the circuit is up on those channels. I am not sure what else to checkk or do? Please send any suggestions
