BRI Port Local LAN Loop Around Test (#618)
This test is destructive
.
This test, which verifies the connectivity of a BRI port across the LAN Bus,
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 Figure 9-14
show how a Loop Around Test is performed
across the Packet Bus for the D-channel.
PASS The port is correctly using its allocated time slots.
1. To be sure that this is not an intermittent problem, repeat this test a
maximum of 10 times to make sure it continues to pass.
2. If complaints still exist, examine the station, connections, and wiring.
