Nortel BCM 400 random reboot after error condition

I have a serious issue w/ my phone system. It's a Nortel BCM 400 still running 3.5 software. About once every 3 months it does a complete reboot, almost like a power cycle, shutting down all services, & causing quite a lot of havoc for about 20 minutes (usually always in the middle of the day). Today, however, I got some new information about what might be happening, but I don't know how to interpret it.

On the system's base phone, the message "Alarm: 44-0" showed up. In the BCM 400's management system (under Diagnostics -> MSC -> Network event log -> items 16 - 20 as most recent), there is a series of several events in a row:

Alarm 044 Severity 8 Repeats 1 Time 20070329125526 Parameters 00

Event 336 Severity 5 Repeats 1 Time 20070329125539 Parameters 00

Event 325 Severity 5 Repeats 1 Time 20070329125627 Parameters 00

Event 328 Severity 5 Repeats 1 Time 20070329125527 Parameters 00

Event 323 Severity 5 Repeats 1 Time 20070329125636 Parameters 00

Can anyone explain this or know what this means?

Event ID: 44 Message: The long term alarm threshold has been surpassed in DTCM %1 for the detection of Remote Alarm Indication. The most likely cause is an irregularity with the PSTN connections. The cable connecting the DTCM to the network termination point or external CSU has been disconnected, or there is a problem with the signal from the network. User action: Check the logs and look for Events ranging from 315-336. If this alarm occurs more than once over a two-week period, contact your local support group. Alarm severity: Critical Trap-type: Error Logs: MSC event 319, Sev=P8, Cat=F
