(PM) Multiframe sync errors?

Thanks for the help on dead air...I think there is a related trouble. Now,
I am seeing this error - multiframe sync - again just over a day after a
reboot that cleared up some mysterious dead air problems (unfortunately
it's impossible to tell if the PM or Bellsouth was responsible since I had
called the circuit in and as usual it mysteriously fixed things...)...it is
interesting that before reboot I had errors also. These errors did not show
up for at least twenty hours after reboot, and are not from resetting the
PM.

Livingston PortMaster PM-3 ComOS 3.8.2
System uptime is 1 days 17 hours 47 minutes

---------------------- line0 - T1 Primary Rate ISDN ---------------

Status: UP Framing: ESF Encoding: B8ZS PCM: u-law

Receive Level: +2dB to -7.5dB

Alarms Violations
----------------------------- -----------------------------
Blue 1 Bipolar 0
Yellow 0 CRC Errors 0
Receive Carrier Loss 0 Multiframe Sync 106
Loss of Sync 1

Before the reboot, line1 was showing errors also. Any ideas as to the
origin of this, or the fix?
