Yep, this circuit is sick. It may even be provisioned incorrectly. You
need to get someone at your telco to stay with you on debugging this.
Tell them you want them to run a loop to your loopback plug at your PM3.
In other words, put your loopback plug on the end of the cable where it
goes into your PM3 and have them run their loop to that point. Tell them
you are putting a hard loop on the cable. That will remove your PM3 as a
target of blame. Or, it will tell you that your PM3 _is_ to blame. :-)
