BRI Port Local TDM Looparound Test (#619)
This test is conditionally 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 Looparound Test runs the following individual tests on the two B-channels
(B1 and B2) associated with the port.
■ A Looparound Test across the TDM Bus for B1.
■ A Conference Circuit Test for B1.
■ A Looparound 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, and maintenance software returns an error code.
FAIL The Looparound Test has failed.
1. If the test fails repeatedly, attempt to reset the circuit pack with the
busyout board PCSS and the reset board PCSS commands if the
other ports on the board are not in use.
2. If the test fails again, execute test pkt P. If this fails, follow failure
procedures in the PKT-BUS section.
3. If the tests in Step 2 pass, the problem is local to the BRI board.
Replace the trunk circuit pack.
PASS The BRI Port Local LAN Looparound Test passed.
