I am trying to hookup a T1 line to a AS5300 router but the T1 controller and serial interfaces go up and then come back down after a few seconds. During the time it stays up, I am able to ping the other end. Have no idea what is causing this problem. All the framing, etc parameters have been set correctly according to the telco's specs.
Thanks in advance

however, right after the T1 goes up, it immediately goes down along with the serial interfaces and there are about 5000 path code and line code violations. I cannot specify the cable length to long either, these are the only choices available:
short short cable
so then I used short and this was the response:
5300(config-controller)#cablelength short 133ft
% Configuration of Short Cable not permitted in CSU mode
is there a way to get out of the CSU mode? I have a good feeling that the cablelength has to be set to long with the gain set as in your sh cntrl response in order to rectify this. Cheers!
