Tests at the same time (for each LCM)
The LCM tests run at the same time when test equipment is available to the
maximum number the BICRELAY_NUM_SIMUL_TESTS parameter
described indicates earlier. LTUs or MTUs must be provisioned to allow the
number of tests that occur at the same time (LCM-level) to run. Because of
real-time considerations, the BICRELAY_NUM_SIMUL_TEST parameter
has a range of one through three. A higher number in this field allows tests for
more LCMs in a given window.
Drawer-level test
The BRT drawer-level test requires the metallic test equipment and a single
NT6X17 line card. The test equiptment and card must be present in each
drawer to test. The system uses the line card to test the BIC relay. The line
card must function correctly. The card must not indicate a diagnostics failure
at the MAP terminal. The system cannot indicate the card as missing (M).
The system places each drawer in a ManB state before the drawer-level test.
Each drawer is out of service for 10 s. During this time, the system suspends
call processing. When the tip and ring reversal relay test on all drawers
completes, the results appear in a single new logutil report PM132. The
PM132 report includes the results of each drawer test of a specified LCM.
When a drawer is out of service or call processing is in progress, the system
skips the drawer. The system tests the drawer on later passes of the BRT.
Single-drawer test
The single-drawer test is for retest purposes when a failure occurs during the
system test. This test is run from the LCM MAP display level. This test is part
of the TST DRWR command. The RELAY option allows the BRT to run
without the main DRWR test. The BRT only runs when the use specifies the
RELAY option. You must set the drawer to ManB before this test runs. The
system prompts the user when the drawer is InSv, ISTb or SysB. The manual
BRT cannot run on a drawer where the LCM node is ManB, SysB, C-side busy
(CBsy) or offline (OffL). A message appears that indicates the request is not
valid. The message gives the current state of the node.
The single-drawer test displays a PM181 log and the results of the test. A
response and a card list that indicates failed drawers appears at the MAP
terminal. When a single-drawer test cannot run, the drawer is not set ISTb.
The drawer can be RTSed to the previous state.
Office-level test
The system BRT uses a new logutil information report, PM132, to display the
results of each LCM-level test.
