Just adding my story to this problem. We are Running PM2ER's with 3.3.3, and are using Multitech
Racks. This random disconnection problem has been going on for a long time now. Trying to trace
the problem I monitor the PM output with debug set to 0x51. I noticed that when a particular
user that complained about this, got disconnected, I didn't see the usual

Received LCP_TERMINATE_REQUEST on port S2 of 0 bytes containing:
05 06 00 04
Sending LCP_TERMINATE_ACK to port S2 of 4 bytes containing:
06 02 00 04

rather he just lost connection with no request being sent to the PM. Looking in the radius
(merit) logfiles, to find the reason for disconnection I saw that it was reported as
Lost-Carrier. So, does this point to the telco and line noise?? Most probably. But could there
be another reason that is PM dependent?? Megazone, any ideas??
