BRI Port Local TDM Loop-Around Test (#619)
This test is conditionally destructive.
Note:
Note:

:
 This test does not execute on a G700 Media Gateway.
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 the following individual tests on the two B channels (B1 and B2) 
associated with the port:
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, and maintenance software returns an Error Code.
FAIL
The Loop-Around test has failed.
1. If the test fails repeatedly, try to reset the circuit pack with 
busyout board location and reset board location if 
the other ports on the board are idle.
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 Loop-Around test passed.
