James,

 

To my knowledge to can not remotely test for hardware problems using
only software.

 

You can however use a hardware loopback plug to test the router/CSU.

 

You will need to have someone connect a T1 loopback cable to your CSU
and reconfigure that controller as a channel group, configure HDLC,
configure an IP address on the interface and then run various ping
tests.  All of this is detailed in this link:

I have a remote site that is down.  This is a cme.  Im able to get into
the gw, and I see that the t1 controller is in a down state.  Is the way
for me to determine if the card is bad or good by doing some type of
loopback config on the gw.  I am remote to the gw.  I think it's a cable
issue,  but want to be sure it not a dead t1 controller card
