The system generates a PM181 log after a complete REX test.
When an InSv or OOS diagnostic test fails, the REX test failure reason
includes the mnemonic. The mnemonic is an-easy to remember abbreviation
of the the failed diagnostic and the failed unit (0 or 1).
The PM600 log contains the start time of each step the REX test that follows.
The PM600 log also contains the unit the REX test step affects and the failure
reason. The REX test steps that the log includes after the failed step are
recovery actions. The REX test initiates these recovery actions because of the
failure. The log includes the unit number when the REX test action is
unit-specific (BSY unit, RTS unit, TST unit, sync). The REX test acion must
not affect the node (SWACT, BSY both units). The additional data of the log
consists of a card list and a mnemonic of the failed diagnostic.
The QUERYPM, QUERYPM FLT, TST REX QUERY and TST REXCOV
QUERY commands contain information on the last REX test. Manually and
system-initiated REX tests store and display a new date, time and status. The
status is passed or failed. The tests store this information in the REX test
maintenance record. The status Passed means the REX test completed without
errors. The status Failed means the REX test did not complete because of an
error. This information is available through the QUERY PM and TST REX
QUERY commands. When the REX test fails, the user performs a manual
RTS, a manual REX test or an automated REX test. The user performs these
actions to return the XPM to service from ISTb.
The system stores a REX test maintenance record for each XPM. The record
contains the following information:
• the REX test scheduler, when the XPM is in the system
• date, time and result (passed or failed) of the last REX test
• failure reason, diagnostics failures and a list of defective cards, if the last
REX test failed
• date and time of earlier failed REX test
• date and time of first passed REX test after earlier failure
The following limits apply to REX tests:
• The system REX test controller runs a REX test on one XPM at a time
when the office uses the NT-40 processor. The SuperNode supports REX
