We were having a problem with a DS3 that terminates in a 3845 that was reporting about 1000 c-bit errors a day. AT&T isolated the problem and fixed it. Now we see about 70 c-bit errors a day.
T3 1/0 is up.
Applique type is Subrate T3
No alarms detected.
MDL transmission is disabled
FEAC code received: No code is being received
Framing is C-BIT Parity, Line Code is B3ZS, Clock Source is Internal

Every once an while we've seen a few errors on this line before but I'm wondering if there is an acceptable amount? Is 69 in a 24 hour period too many? At what point should we be concerned?
Thanks
