Hi,
I have a T1 CSU ACE in place between the telco's smartjack and our endpoint equipment, which happens to be a Brooktrout TR1034 fax board. I actually picked up the T1 CSU ACE specifically because we were seeing quite a few CRC errors recorded by the card (among some other issues, telco-related), and were hoping it would clear them up. We inserted the T1 CSU ACE and had the telco do an hour-long loopback test to it (which they swear they did) and they were unable to record any errors on the circuit whatsoever. In the meantime, we are still accumulating errors on the endpoint device.
Any thoughts about this so far? Should we still be seeing CRC errors on our endpoint, even if it's only a couple of feet from the CSU (shouldn't that eliminate CRC errors?)
This is the kind of frequency/timing we're talking about (from the TR1034's log):
