OK so that means they probably have no monitoring points on the T-1 so they are looking at the history in their switch. They should still see something. Do as OBTW suggest, ask for a performance monitor to be put on the circuit and when you see errors call them, especially if you see any alarms. If they are just taking it down to test and there are no errors at the time of test they won't see anything. They need to monitor the T-1 live.
