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:
1144 ABORT The PPN Packet Bus is out-of-service.
1. Follow the repair procedures for the Packet Bus.
2. After completing Step 1, execute the test port long
PCSSpp command, and review the results of the
BRI Port Local LAN Loop Around Test to verify the
repair.
2012 ABORT Internal System Error.
2100 ABORT Could not allocate the necessary system resources to
run this test.
1. Retry the command at one-minute intervals a
maximum of five times.
2. If the test continues to abort, escalate the problem.
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 pkt P 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.
