Error Test
Code Result Description / Recommendation
2012 ABORT Internal system error.
2100 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
2. If complaints still exist, examine the station, connections, and wiring.
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.
