We're staging a DS3 mux to aggregate T1s back to a PA-MC-2T3-EC in a
7206VXR (G2) running 12.4(15)T7. 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 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.

I can't find any way to set the line code on the 7206 for the individual
T1s. The virtual serial ints only have an IP on them at this point.
Everything is unshut. Any idea what I could be missing? What's causing
all the path and line code violations?
Thanks
Justin
