Create a T1 crossover cable. Wire pin 1 (near) to pin 4 (far). Wire pin 2
(near) to pin 5 (far). Wire pin 4 (near) to pin 1 (far). Wire pin 5 (near)
to pin 2 (far).

Set the clock source on one end to internal.

conf t
int sX/Y
service-module t1 clock source internal
^z

Should be happy as a clam. Be sure to remove the clock source when running
over a telco.

Swap TxC/TxD and RxC/RxD (pins 1 and 2 to pins 4 and 5, and vice
versa.)

You need a t1 crossover cable, and you need to set one of the wics to
provide clocking.

conf t
int ser 0
service module t1 clock source internal

A t1 crossover is pinned this way:

1 -> 4
2 -> 5
4 -> 1
5 -> 2
