The line code for individual T1s is handled on the MUX. Based on the counters of line code violations, I'd check there first and see what it is set to.

I haven't channelized a T3 before so I'm feeling my way through this. It looks to be relatively simple but I'm getting tripped up somewhere. On the 7206: controller T3 1/0 cablelength 10 logging-events detail t1 1 channel-group 0 timeslots 1-24 t1 2 channel-group 0 timeslots 1-24 t1 3 channel-group 0 timeslots 1-24 t1 4 channel-group 0 timeslots 1-24 t1 5 channel-group 0 timeslots 1-24 t1 6 channel-group 0 timeslots 1-24 t1 7 channel-group 0 timeslots 1-24 t1 8 channel-group 0 timeslots 1-24 t1 9 channel-group 0 timeslots 1-24 t1 10 channel-group 0 timeslots 1-24 t1 11 channel-group 0 timeslots 1-24 t1 12 channel-group 0 timeslots 1-24 t1 13 channel-group 0 timeslots 1-24 t1 14 channel-group 0 timeslots 1-24 t1 15 channel-group 0 timeslots 1-24 t1 16 channel-group 0 timeslots 1-24 t1 17 channel-group 0 timeslots 1-24 t1 18 channel-group 0 timeslots 1-24 t1 19 channel-group 0 timeslots 1-24 t1 20 channel-group 0 timeslots 1-24 t1 21 channel-group 0 timeslots 1-24 t1 22 channel-group 0 timeslots 1-24 t1 23 channel-group 0 timeslots 1-24 t1 24 channel-group 0 timeslots 1-24 t1 25 channel-group 0 timeslots 1-24 t1 26 channel-group 0 timeslots 1-24 t1 27 channel-group 0 timeslots 1-24 t1 28 channel-group 0 timeslots 1-24 I've got a spare 2811 with a VWIC-2MFT-T1 on the other end configured like this: controller T1 0/1/0 framing esf linecode b8zs cablelength short 133 channel-group 0 timeslots 1-24 ! controller T1 0/1/1 framing esf linecode b8zs cablelength short 133 channel-group 0 timeslots 1-24 Clock source is internal on the 7206 and line on the 2811. Everything else assumed the default settings. In the middle is a new Wide Bank 28 that was set up by one of our telco guys. He said the necessary config is minimal. My T3 is up but I'm down/down on the serial ints on both ends. I can manually loop up the 2811 at the VWIC and the int comes up. I can loop it up at the biscuit jack on the 2811's side of the mux and the appropriate T1 on the 7206 comes up. To me that makes me think the mux is fine and that both ends are fine (at least from their perspective). So that makes me think that something isn't matching up on the 7206 and 2811. The linecode on the T3 is B3ZS of course and framing for the T1 is ESF. The T1 on the 2811 is B8ZS and ESF. On the 7206: 7206-1.amherst#sh controllers t3 1/0 br T3 1/0 is up.
