Customer with a PRI provided by local cable provider.

PRI will go down doesn't show down on 9100 but if you unplug the PRI cable and replace it with a straight through cable get the red alarm on the PRI MTA from the carrier and then plug back in the crossover T1 cable comes right back up and all is good for what appears to be around 24 hrs it has done this several times.
Carriers says they see CRC errors but no SLIPS/.


Have the same setup with another client right down the road and have never had an issue in the 4 years it was installed. This was fresh installed 3 days ago.

TIA,
Gary
