XPM diagnostic history

The Extended Peripheral Module diagnostics history, feature number
AF5006, provides a resident database to record selected diagnostic results of
XPMs. This feature records diagnostic results that indicate XPM sanity.
The data in this database can affect DMS maintenance activities. This
database provides operating company personnel with
to data on the accumulated results of diagnostics. The system retains data in
the history database over warm, cold, and reload restarts. This feature is part
of software package New Peripheral Maintenance NTX270AA, and is not an
optional feature.
This feature is one of a group of three related features. The two remaining
features include the XPM PreSWACT/Post SWACT Audit, feature number
AF5007. The other feature is the XPM REX Control and Trouble
Notification Improvements, feature number AF5008. Feature AF5007 uses
a subset of diagnostic results with past REX tests and SWACT results to
determine if a SWACT must occur. This text refers to the functionality that
feature AF5007 introduces as the SWACT controller. Feature AF5008
modifies the XPM REX test to use the SWACT controller and provide log
improvements.
An XPM can run diagnostics to test the function of the XPM hardware.
Diagnostics can run as a result of CM or XPM requests. Diagnostics the
XPM performs are part of XPM audits. The SWACT controller and
operating company personnel use diagnostic results that feature AF5006
provides for system analysis.
SWACT controller
This feature provides short term diagnostic performance data to the SWACT
controller. A set of query procedures are provided for applications that
require the information. The SWACT controller determines if a SWACT is
authorized. Short term data for a specified unit means diagnostic and audit
failure counts, measured from the last time a unit gained activity.
