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.

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.
