I have CS1K 7.5 system, and my 3 PRI2 circuits are acting all foolish and taking continual CRC hits. This issue recently started, but for now anyway the PRI2 loop/DCH are UP on all 3 of the circuits. I'm getting continual DTA300, DTA311 errors even after DIS/ENL the CC, DCH, and LOOP a few times with no change. i even went as far as downing the MSDL card for each PRI2, then re-enable w/FDL. My guess is the carrier, but i wanted to see if there may be another ideas out there. I have allready checked LD73 DDB, LPTI, and SYTI programming and everything checks out accordingly. Let me know, thx
 
try dropping the one that has the clock controller on it (DIS DCH and LOOP), changing the CRC settings in LD 73 to the other option (ON if its currently OFF or OFF if its currently ON) and then bringing it back up (LD 60, rcnt, enll <loop number>, trck pck <loop shelf>, LD 96 enl dch <dch no>). See if that loop steadies. If it does then change the rest, I have had it where carrier is doing some work (upgrade etc,) and they miss config the CRC.

Or you go to the carrier an say currently we have CRC ON/Off and getting lots of errors what you set for.
 
the carrier reset their equip, and everything was good to go as expected. thanks again BigNose21
