First you'll need a T1 crossover
PIN-=>PIN
1-=>4
2-=>5
4-=>1
5-=>2
second, set on CSU to clock source internal, and the other
to clock source line, linecode/framing/data-coding/ and timeslots must be
the same
from that point, you can treat it like a normal serial line, changing encap
etc..
You could use frame encap, but you need to do a no keepalive (to turn off
LMI)
(if your not going to be using a frame switch)
Thanks,
Rob Hopkins
