Note:
the I-CSU/T1 sync splitter only, the ELB test is also executed as part of
test ds1-loop location ds1/csu-loopback-tests. Try to clear the
alarm using busyout board location, test ds1-loop location ds1/
csu-loopback-tests, and release board location. If the ELB test
continues to fail, then either the UDS1 board, the CSU module, or the I/O cable
between the backplane and the CSU module, or any combination thereof, failed.
Try to isolate where the failure is occurring by re-executing the test and by
replacing one piece of hardware at a time.
p. Error Type 1312: RLB failure. This error occurs when the Repeater Loopback (RLB) test
fails for the Integrated CSU (I-CSU) module/T1 sync splitter or for the 402A or 403A E1
synchronization splitter. This test is executed by the I-CSU/E1SS during I-CSU/E1SS
power-up/reset (i.e., DS1 board physically inserted and 120A1 CSU module or the 401A T1
sync splitter, or the 402A or 403A E1SS is already installed) or when the 120A1 CSU
module or the 401A T1 sync splitter, or the 402A or 403A E1SS is plugged on to an already
initialized DS1 board.
Note:
the I-CSU/T1 sync splitter only, the RLB test is also executed as part of the
test ds1-loop location ds1/csu-loopback-tests. Try to clear the
alarm using busyout board location, test ds1-loop location ds1/
csu-loopback-tests, and release board location. If the RLB test
continues to fail, replace the CSU module.
q. Error Type 1313: CPE Loopback Jack deactivation error. This error occurs when the UDS1
circuit pack could not deactivate a CPE Loopback Jack on power-up/reset or upon software
request.
Try to clear the alarm using busyout board location, test ds1-loop location
end-loopback/span-test, and release board location. If the attempt to
deactivate the CPE Loopback Jack continues to fail, other steps must be taken to
deactivate the loopback.
r. Error Type 1314: far CSU Loopback deactivation error. This error occurs when the UDS1
circuit pack could not deactivate a far-end CSU loopback on power-up/reset or upon
software request.
Try to clear the alarm using busyout board location, test ds1-loop location
end-loopback/span-test, and release board location. If the attempt to
deactivate the Far CSU loopback continues to fail, escalate the problem.
s. Error Types 1400, 1401: echo cancellation errors are logged when:
● Error 1400: echo canceller function failed. The Echo Canceller Function test, which is
executed by firmware, failed.
● Error 1401: echo canceller memory failed. The Echo Canceller Memory test, which is
executed by firmware, failed.
