BRI Port Local LAN Looparound Test (#618)
This test is destructive.
This test checks the connectivity of the BRI port across the LAN bus. Because this
test is destructive, run this test only if the port is out-of-service.
Failures of this test indicate either on-board faults associated with the TBRI-PT
hardware on the circuit pack or problems with the LAN Bus, which is used to form
connectivity between the switch and the TBRI-PT.
If the port is in a state other than out-of-service, the BRI Port Local LAN
Looparound Test will abort. If the port is out-of-service, then the port is put into a
local looparound mode and the following test is executed.
A looparound test is performed across the 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 bus is alarmed in the Processor Port Network (or the port network
in which that circuit pack resides) or if the Packet Interface 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 bus.
1, 2
FAIL
The NPE of the tested port was found to be transmitting in error, causing
noisy and unreliable connections. Error code 1 indicates that the NPE
Crosstalk Test failed on Channel B1. Error code 2 indicates that the NPE
Crosstalk Test failed on Channel B2.
1. Replace circuit pack.
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 ensure it continues to pass.
2. If complaints still exist, examine the connections and wiring.
