Restarts
The following information applies to manual and system-level restarts:
• warm or cold
— the system aborts all drawer-level tests.
— the system saves ISTb reasons.
— All LCM-level tests stop and are system level when the tests are in the
window. The test resumes after the restart. The system does not retest
the LCMs.
• reload
— The system resets BRT as if the RESET option of the BICRELAY
command is issued.
— The system retains the ON/OFF settings of the BICRELAY command.
— The system retains the state of the SUPPRESS/ALLOW commands.
— The system clears the ISTb reasons.
Interactions
This feature uses the test access bus, the MTE and a single NT6X17 card in
each drawer to complete tests. The ALT and the BRT cannot run at the same
time. This action delays both tests because both tests use the same test
equipment.
When REX runs on a set LCM, BRT does not run on that LCM. The LCM
remains in the current state. The system outputs a PM181 that indicates the
BRT does not run because of the REX in progress.
Limits
The following limits apply to this feature:
• The system test manually busies the logical drawer before the system runs
the RELAY test. When lines are in a call processing busy state, the system
skips this drawer for this test cycle.
• The drawer must be ManB before a manual BRT runs on a single drawer.
• The user must enter all NT6X17 line in each logical drawer. When this
requirement does not occur, the system does not test the drawer.
• When the line card selected for tests is removed during the test, the drawer
fails.
• When a drawer fails to RTS when the system BRT is complete, the system
places the drawer SysB. The system audit can attempt to return the drawer
to service.
