BRI Port Local LAN Loop Around Test (#618)
This test is destructive.
This test verifies the connectivity of a BRI port across the LAN Bus and executes
only if the port is out-of-service. The test aborts if calls associated with the port
are in-progress. Failures of this test indicate either on-board faults associated
with the BRI-PORT hardware on the circuit pack, or problems with the LAN Bus,
which is used to form connectivity between the switch and the BRI-PORT.
The dotted lines in
show how a Loop Around test is
performed across the packet bus for the D channel.

ABORT
Could not allocate the necessary resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
1, 2
FAIL
The NPE of the tested port was found to be transmitting in error. This causes
noisy and unreliable connections. Error code 1 indicates that the NPE
Crosstalk test failed on Channel B1. Error code 2 indicates that the NPE
Crosstalk test failed on Channel B1.
1. Replace the circuit pack.
PASS
The port is correctly using its allocated time slots.
1. To verify that this is not an intermittent problem, repeat this test up to 10
times to make sure it continues passing.
2. If complaints still exist, examine the station, connections, and wiring.
