Default Problems Installing T1 Trunk on CM

Good Day Everyone,

I was wondering if you could offer me some assistance. I am trying to configure a partial T1 trunk on a CM:

The Trunk is a PRI with 10 Channels and Uses a DMS100 Protocol.

I have configured the ds1 with line codding: b8zs and framing mode esf, signalling mode: isdn-pri, connect: network, protocol 1,Protocol Version: c,

I have problems where when I check the status of the trunk it is our of service. When I check the board the physical connection is up but get test No. 140, 143, 144, 145 FAIL.

Any ideas of what can cause this or how to fix?

Hi dlake,

Can you tell me the output of status trunk and status signaling.
Are the channels out from near end or far end?
