leased line problem

got a leased line between two routers.

End A- this end, has a wic-1dsu-T1 - configured to use all 24 channels.

End B - this end has a nm-hda module with vwic-mft-2t1-DI (drop and insert) card on it. (configured with framing - esf, linecode b8zs, and configured with a channel group to use 24 channels).

End A has clock source from the line. While End B has clock source as internal.

The controller stays up, but the line protocol is still down.

Are there any issues with connecting these two different WICs as termination point for the leased line ?

Here are some outputs for troubleshooting.

End B - show interface serial output.

configuration at End B

controller T1 2/1

framing esf

clock source internal

linecode b8zs

channel-group 1 timeslots 1-24

-----------------------------------

configuration at End A

int s0/0

service-module t1 timeslots 1-24

I will get the outputs for serial interface on this end, shortly.

Re: leased line problem

Try changing End B's config to the following:

Controller T1 2/1

channel-group 1 timeslots 1-24 speed 64

The service module should default to 64K while the controller CSU/DSU defaults to 56K.
