Out of service unit tests
BIC tests are run during out-of-service LCM unit tests. Only drawers that have
the ISTb or SysB state are tested by drawer tests. For this reason,
out-of-service unit tests consider drawers previously identified with faults as
follows:

BICRELAY command
The CI level BICRELAY command allows the user to enable, disable, reset,
allow, or not allow the PM181 drawer state to change logs when a given LCM
or Star Hub undergoes the system BRT. Operating company personnel can

Note: The PM181 logs associated with the LCM or Star Hub being tested
by the BRT are not allowed to be output. Other PM181 logs associated with
other LCMs or XPMs are allowed.
The following paragraphs describe the BICRELAY command parameters.
ON The ON parameter enables the test to begin at the planned window. A
message displays that indicates the test is ON. If the current date and time is
within the planned window, the office-level test starts immediately. If any tests
are in progress when this command is supplied a message displays, indicating
the user must wait until all tests are complete before restarting the BRT. This
option does not change the operation of the manual TST command at the
STAR MAP display level.
OFF The OFF parameter does not allow the office-level test to resume. A
message displays that indicates the test is OFF. Any system BRTs now in
progress are allowed to complete. This parameter is the default.
After the test is disabled, the test does not begin until enabled by using the ON
option. Once enabled, the office-level test continues at the point where it was

With both units out of service, any drawers with the SysB state are changed
to the ISTb state so they can be tested by the out-of-service test. If the fault
remains, the drawer is reset to SysB. If drawers are no longer ISTb, the
state changes to InSv.
With one unit out of service, only the drawers that have the ISTb and the
InSv states are tested. This limit is because the mate unit is InSv and now
in control of all drawers. Drawers with a SysB state are not changed or
tested.
