I've seen several good suggestions for you pass by this afternoon but you
might also try looping this circuit yourself to see if everything is OK
from the telco demarc to the PM3. Unplug the cable from the telco
smartjack to your PM3, put a loopback plug on it, and see if you keep
accumulating errors. I would reboot the unit at that point since you'll
have killed all the connections when you disconnected the cable and you'll
want to zero the counters. There is a loopback command on the PM3 also.
This simple test will help you keep the telco from pointing fingers your
way and/or identify bad internal wiring. If you can't run clean in this
configuration then the problem is probably your internal wiring.
