BRI Port Local LAN Looparound 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.
The dotted lines in Figure 10-5 show how a Looparound Test is performed across
the Packet Bus for the D-channel.
