Utr Diagnostic - Nortel DMS-100 Series Maintenance Manual

9-46 Trouble isolation and correction
This diagnostic provides the SMS with both InSv and OOS diagnostics.
This diagnostic also provides the SMS with a CMR audit. The CMR audit
activates the InSv diagnostic on a normal base. The feature provides a
diagnostic interface to report CMR failures.
The system logs results of the CMR diagnostic test as a PM181 audit
exception report. The PM181 audit exception report lists the failed card list.
The PM181 audit indicates that the CMR diagnostics detect the fault.
To run the CMR diagnostic, enter the command string
>TST UNIT # CMR.

UTR diagnostic

The UTR diagnostic tests the 6X92 UTR card. The diagnostic tests the
following:
297-8231-550 Standard 09.01 August 1998
The InSv diagnostic provides an interface with and controls the on-board
firmware diagnostics. These diagnostics continuously test different
critical components of the CMR card. This diagnostic runs one time
each minute as an InSv request audit. Operating company personnel can
request the InSv diagnostic. To request the InSv diagnostic, the
operating company personnel enter the command string
. The diagnostic triggers methods that result in thorough InSv
CMR
coverage of the CMR card.
The OOS diagnostic is a more complete test of the functionality of
required CMR hardware. This diagnostic uses some of the same
on-board firmware diagnostics as the InSv tests. The diagnostic allows a
more complete testing of all resources where time limits or normal InSv
traffic normally limit testing.
The CMR audit helps to run this audit on a normal base. The facility
audit normally used for this purpose runs on intervals of 7.5 min. The
interval is too low to provide detection time for the CMR card. This
feature has a new audit.
