BRI Port Local TDM Loop Around Test (#619)
This test is destructive.
This test verifies the connectivity of a BRI port across the TDM Bus. It aborts if
calls associated with the port are in progress. Failure of this test indicates an
on-board fault associated with the port hardware on the circuit pack.
This Loop Around Test runs a series of individual tests on the two B-channels (B1
and B2) associated with the port. It is a collection of the following:
■ A Loop Around Test across the TDM Bus for B1.
■ A Conference Circuit Test for B1.
■ A Loop Around Test across the TDM Bus for B2.
■ A Conference Circuit Test for B2.
The tests are run in the above order. If one fails, the remaining tests in the
sequence are not executed. An error code is returned at that point.
This test is not executed for ABRI-PORT/ATT-PORT/LGATE-PT/ATTE-PT
because the B-channels associated with the port are not used by ASAI or Avaya
adjuncts.
2100 ABORT Could not allocate the necessary system resources to run this
test.
1. Retry the command at 1-minute intervals a maximum of 5
times.
FAIL The Loop Around Test has failed.
1. If the test fails repeatedly, attempt to reset the circuit pack
if the other ports on the board are not in use. Reset the
circuit pack by issuing the busyout board PCSS and the
reset board PCSS commands.
2. If the test fails again, execute test port-network <pn#> on
the G3MT terminal. If this fails, follow failure procedures in
PKT-BUS section.
3. If tests executed in Step 2 pass, the problem is local to the
BRI board. Replace the circuit pack.
PASS The BRI Port Local LAN Loop Around Test has passed.
