Cmr Diagnostic - Nortel DMS-100 Series Maintenance Manual

When a system audit detects a SysB link, the DMS-100 generates the
following PM110 log:
PM110 MAY16 09:27:33 4899 INFO CARRIER SMS 60
CARRIER–NO: 8, REASON: REMOTE LINK SYSBSY
When a link is RTS, the SMS and RCS leave the ISTb state and enter the
InSv state. The SMS and RCS can leave the ISTb state if there are no other
faults present. The DMS-100 switch generates a PM106 log if there are no
other faults present. The DMS-100 switch generates a PM184 log when a
link is RTS. Refer to the examples that follow:
PM106 MAY16 11:23:33 4877 RTS SMS 60
Node
Unit0 Act: InSv
Unit1 Inact: InSv
PM184 MAY16 09:33:00 7677 RTS SMS 60
With an OOS link, the
common equipment digroup loopback test. This test checks the ability of
the RCS to assign channels on a link through the time switch card. The test
checks all RCS common equipment involved in the PCM path. This
equipment includes:
maintenance
supervisory
switch
digroup cards
The SMS A/B-board diagnostics firmware implements a diagnostic for the
A/B-derived data link message card (A/B-DDL). The diagnostic runs a
series of tests on the card and returns a pass or fail message. The message
depends on the test results.
The SMS SP and the A/B-DDL 8085 microprocessor execute tests on the
A/B-DDL card. The SP issues commands to the 8085 microprocessor to
execute tests. The SP monitors the test results.

CMR diagnostic

The CLASS modem resource (CMR) card is self diagnosing. The card
contains on-board firmware that provides the current card level diagnostic.
The primary function of the diagnostic is to detect faults that affect service.
