The up/down means the serial interface sees carrier but the protocol is
down. Make sure you have the encapsulation specified correctly. Also, make
sure that you have specified the correct channels for the T1, i.e if you're
only using a few of them.

If your LP and CD light are green you are cool. Look at the manual that came
with it it tells what each light means.
Use the command to put your interface in loop-back. If the LP light turns
yellow and the CD stays green your card is fine.

Subject: Internal CSU
I can't find any online help for troubleshooting Cisco's internal CSUs.
I have two routers, one on each end of a T1 circuit. Each router has a T1
WIC
in it.
The interfaces are UP DOWN. If I turn on the loopback button on the remote
router the local end comes UP UP. Both routers have keepalives enables and
the
circuit has been verified to be B8Zs all the way through. The WICs are set
to
their default value. I also tried adding clocking on one end - no luck.
Any ideas?
