The system stores a REx maintenance record for each XPM that contains the
following information:
REx scheduler, if the XPM is in the system
date/time and result (passed/failed) of the last REx
failure reason, diagnostics failures, and a list of defective cards (if it
applies) if the last REx failed
date/time of previous failed REx
date/time of first passed REx after a previous failure
The following restrictions apply to REx tests:
The system REx (SREx) controller only runs REx on one XPM at a time
if the office uses the NT-40 processor. Super Node supports REx tests
that run in order for a maximum of ten XPMs with the same REx test
class.
For REx to run, the node must be one of the following:
— InSv
— ISTb because of a REx test failure
— in-service trouble because P-side DS-1 links are out-of-service.
If the system cannot start a Warm SWACT, REx terminates.
After correct completion of REx, the XPM has a new active unit,
because of the SWACT.
