Media Gateway Controller Local Diagnostic Shells - Nortel 1000E Maintenance Manual

Resident Trunk Diagnostic
This program automatically monitors all trunk calls and records apparent
faults on each trunk. If the number of faults on a trunk exceeds the threshold
for that trunk, the program generates a system message identifying the
trunk and the type of fault.
A failure on a trunk can keep the trunk from detecting incoming calls. The
threshold mechanism cannot detect such a failure, so this program also
records the number of days since each trunk received an incoming call. If
some incoming calls are not being processed, use the command LMAX in
Trunk Diagnostic 1 (LD 36) to identify the trunk with the maximum idle days.
System Loader
The System Loader program loads all call processing programs and data
and starts memory-checking diagnostics. After all required programs
and data are loaded and all checks performed, the System Loader is
erased from system memory, the Initialize Program runs, and normal call
processing begins. This process is called a sysload (or system reload). The
System Loader operates automatically on system power-up or if a core
equipment or power fault destroys information in the system memory.

Media Gateway Controller Local Diagnostic Shells

You can perform maintenance functions specific to the Media Gateway
Controller (MGC) through Local Diagnostic Shell 1 (LDB1) and Local
Diagnostic Shell 2 (LDB2). LDB1 provides MGC-specific functions similar
to the PDT1 shell functions on the Call Server. LDB2 provides advanced
functions similar to the PDT2 shell functions on the Call Server.
Access the LDB shells locally on an MGC serial port or remotely through
rlogin, telnet, secure shell, or PPP. Passwords for the MGC platform
are synchronized with passwords on the Call Server. Therefore, when
logging on to LDB on the MGC, enter the Call Server PDT1 user name
and password to access LDB1 and the Call Server PDT2 user name and
password to access LDB2. To access the VxWorks shell, enter su from the
LDB2 Command Line Interface (CLI).
When you log on to the MGC, the following login banner appears:
