This test is destructive.

Note:

 / 

:

 This test does not execute on a G700 Media Gateway.

This test checks the connectivity of the BRI port across the LAN bus. Because this test is 
destructive, it is only attempted if the port is out-of-service. This test is run only as a demand 
test.
If the port is in a state other than out-of-service, the BRI Port Local LAN Loop-Around test will 
abort. If the port is out-of-service, then the port is put into a local loop-around mode and the 
following test is executed.
A loop-around test is performed across the Packet bus for the D channel. The switch sends 
data over a packet connection, which is looped back by the BRI port (D channel) and received 
back by the switch. The test passes if the packet connection can be established and the 
transmitted data is received unaltered. The test aborts if the Packet bus is alarmed in the 
Processor Port Network (or the port network where that circuit pack resides) or if the Packet 
Interface board is out-of-service. The test fails due to either on-board faults associated with the 
BRI port hardware on the circuit pack or problems with the LAN bus.

PASS

The port is correctly using its allocated time slots.

1. To be sure that this is not an intermittent problem, repeat this 

test up to 10 times to ensure it continues to pass.

2. If complaints still exist, examine the connections and wiring.
