2 FAIL The CLJ-LB test failed because it was not set up properly. The DS1 interface
pack could not successfully put the CPE loopback jack into loop back mode.
1. Rerun the test ds1-loop UUCSS cpe-loopback-jack-test-begin
command.
2. If the test continues to fail, the problem could be with the TN767E board,
the CPE loopback jack equipment, or somewhere between. Run the test
ds1-loop UUCSS ds1/csu-loopback-tests command to determine if the
loopback tests that are closer to the TN767E board are successful. If any of
these tests fail, follow the maintenance strategy that is associated with the
test that fails.
3 FAIL The CPE Loopback Jack Test was not set up properly. The framed 3-in-24 test
pattern, generated by the DS1 Interface circuit pac k and looped back through
the CPE Loopback Jack, could not be detected properly by the DS1 circuit
pack.
1. Retry
t
est ds1-loop UUCSS cpe-loopback-jack-test-begin.
2. If the CPE Loopback test continues to fail, the problem could be with the
TN767E board, the CPE Loopback Jack equipment, or somewhere in
between. Run test ds1-loop UUCSS ds1/csu-loopback-tests to see if the
loopback tests closer to the TN767E board are successful. If any of those
loopback tests fail, follow the maintenance strategy associated with those
loopbacks.
PASS The CPE Loopback Jack test has successfully began executing. The test will
continue to run until the system technician enters the
t
est ds1-loop UUCSS
end-loopback/span-test command or the release board UUCSS command.
