We are configuring a simple P2P T1 using a 2620 Router with a 2 port Wic card CSU/DSU T1 and a 1721 Router with a single Wic Card CSU/DSU T1 on the other end.

At the 2620 end, serial 0/2 is showing:

Loopback (Inband CSU Code) and we can't seem to get rid of this. We think that it is interfering with our setup.

We have green lights on both ends, however, it shows that the serial up, line protocol down. The 2620 clock is set to "internal" and the 1721 is set to "Line".

Any suggestion?
Thanks
