System Technician-Demanded Tests:
Descriptions and Error Codes
Always investigate tests in the order presented in the following tables when
inspecting errors in the system. For example, by clearing error codes associated
with the ASAI Port Local LAN Looparound test (#618), you may also clear errors
generated from other tests in the testing sequence.

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 ASAI-PT hardware on the circuit pack or problems with the LAN Bus,
which is used to form connectivity between the switch and the ASAI-PT.
