NIU, facilities, soft switch. these are just some of the things I have dealt with. I've only had two bad XTS T1 boards ever. While fighting with the provider, I usually show my customer where the line in is located on the CSU. By unplugging the T1/PRI at that point, there is no keep alive to deal with. Then when plugging it back in, a loop back almost always resynchronizes it. While this doesn't completely rule out a local hardware issue, it really suggests that it is something in the CO. What I really hate is when the CO loops it down for testing, says no problem found, then loops it back up. They just don't seem to realize that the act of looping it down and up resets the circuit. It is now up to us to do part of their work for them before they invest a knowledgeable tech on our trouble ticket.
