We recently had a major communications failure in our building when SBC had lost a pairgair (whatever that is, from what I understand, its a data multiplexer, ANYWAYS). During the outage, our telephone switch was the only telephone system working at the time (everyone else went thru SBC). We did not realize until the next day that we had a problem until the call volume started to pick up and everyone's calls were going out sometimes, and others the switch would give a fast busy. When our local CLEC came out to look at the problem, they said they were "looking at the T1 to see if it was getting any hit." They found that during the outage, one of our two T1's got disabled in the switch (leased line by SBC).

Now that I told my story , can anyone tell me the command to test/see the status of our T1's? Any help would be appreciated.
