When the tip-and-ring reversal relay test on all drawers completes, the results
display as a PM132 log report that includes the results of each drawer test of a
given LCM. If a drawer was previously out of service or call processing is
currently in progress, the drawer is not tested. The drawer is tested on future
passes of the BRT.
Single-drawer test The single-drawer test is for repeat test purposes if a
failure occurs during the system test. This test is run from the LCM MAP
display level and is part of the TST DRWR command. The RELAY option
allows the BRT to run without running the main DRWR test. The BRT is not
run unless the RELAY option is defined. The drawer must be ManB by the
user before this test is run. The system prompts the user if the drawer is InSv,
ISTb, or SysB. The manual BRT cannot be run on a drawer where the LCM
node is ManB, SysB, C-side busy (CBsy), or offline (OffL). A message
displays indicating the request is invalid and gives the current state of the node.
The single-drawer test displays a PM181 log with the results of the test. A
response is also displayed at the MAP terminal with a card list indicating the
drawer that failed, if necessary. If a single-drawer test cannot be run, the
drawer is not set ISTb and can be returned to service to its previous state.
Office-level test The system BRT displays the results of each STAR-level test
in a new information log report, PM132.
PM132 provides a report of each drawer-level test in an LCM as follows:
• test passed
• reversal test failed
• test was run but drawer failed to RTS after test
• test not run because of
— line card not available
— problems found using the MTE
— being aborted
— drawer being previously out of service
— call processing being currently in progress
— bad hardware
— message link problems
— unavailable resources
— an invalid load in the Star Hub
— an unexpected error condition
— conflicts in maintenance software
