2 FAIL The test failed because it was not set up properly. The
UDS1 pack could not successfully put the far-end CSU
into loopback mode.
1. Rerun the test ds1-loop PCSS
far-csu-loopback-test-begin command.
2. If the test continues to fail, the problem could be with
the TN464F board, the CPE loopback jack
equipment, or somewhere between. Run the test
ds1-loop PCSS cpe-loopback-jack-test-begin
command to determine if the CPE loopback jack
loopback test is successful. If a CPE loopback jack
device is not being used, issue the test ds1-loop
PCSS ds1/csu-loopback-tests command instead.
If the closer loopback test fails, follow the
maintenance strategy that is associated with that
test; otherwise, escalate the problem.
3 FAIL The Far CSU Loopback Test was not set up properly.
The framed 3-in-24 test pattern, generated by the UDS1
Interface circuit pack and looped back through the
far-end CSU, could not be detected properly by the
UDS1 circuit pack.
1. Retry the
test ds1-loop PCSS
far-csu-loopback-test-begin
command.
2. If the Far CSU Loopback test continues to fail with
this error code, the problem could be with the
TN464F board, the far-end CSU equipment, or
somewhere in between. Run the
test ds1-loop
PCSS cpe-loopback-jack-test-begin
command to
see if the CPE Loopback Jack test which is closer to
the TN464F board is successful. (If a CPE Loopback
Jack device is not being used, then run the
test
ds1-loop PCSS ds1/csu-loopback-tests
command
to see if these even closer loopback tests succeed).
If the closer loopback test fails, follow the
maintenance strategy associated with that
loopback. Otherwise, escalate the problem.
