8-26 RSC-M trouble isolation and correction
Diagnostics can be grouped together and run as a set of diagnostics or run as a
single test. Common sets are:
•
•
•
•
In-service and out-of-service tests
In-service and out-of-service tests are solicited tests. These tests run only as a
result of CC requests. The system can use a manual TST command, manual
or system RTS, SWACT, BSY or REX commands to request a test on an XPM
unit. When the CC makes this request, the XPM runs a set of diagnostics. The
diagnostics included in the set depend on the PM type of the XPM, the state of
the XPM unit, and the activity of the XPM unit. If the unit is InSv, the XPM
runs a set of in-service diagnostics. If the unit is OOS, the XPM runs a set of
out-of-service diagnostics.
The results of separate diagnostics return to CC along with a final result for the
entire set. If any cards are defective, the system generates a card list and
transfers the list to CC at the end of the set of tests.
Facility audit
The facility audit is a set of diagnostics the XPM runs to test the XPM. If the
audit detects problems, the audit sends a message to CC. This message
indicates the problem and a list of defective cards.
ROM diagnostics
If the XPM is at ROM level, a set of ROM diagnostics can run.
This feature does not capture failures. This feature does not capture the cards
mate and ROM diagnostics use. The system generates a card list or log at the
MAP terminal for each diagnostic. The system does not record a card list or
diagnostic failure is recorded in the diagnostic history.
The following table lists and describes the diagnostics associated with the
RSC-M that this feature supports. The table classifies the diagnostics as
solicited, audit, or both. The table identifies the diagnostics that the SWACT
controller requires.
