I have a 3725 with two two port T1 WIC's in W0 and W1. In W2 I have a T1-CSU/DSU-T1-V2 WIC. I am recieving a cd green light and an alarm light. The serial interface 0/4 is showing down and down. I want to confirm a correct configuration. Currently I have
S0/3
interface Serial0/4
ip address x.x.x.x 255.255.255.252
fair-queue
service-module t1 clock source internal
service-module t1 timeslots 1-24
linecoding is set to esf and framing is set to b8zs. I have set encapsulation for ppp. Does it look like I'm missing anything?

Are you certain that the clock should be set to internal? In many cases, the clock is generated by the provider and clock source should be set to "line"
You should see lots of RX-errors if there is a conflict with the clocking. Check your provider to be absolutely certain.

Thx for the response. Yes I did confirm that with the carrier. We just had a tech disbatched, turns out the smart jack was programed for a 56k circuit not a T1. Flipped a switch and we're up and running.
Thx again.
