o. Error Type 1311 — ELB failure. This error occurs when the Equipment
Loopback (ELB) test fails for the Integrated CSU (I-CSU) module. This test
is executed by the I-CSU during I-CSU power-up/reset (i.e.- UDS1 board
physically inserted and 120A1 CSU module) or when the 120A1 CSU
module is plugged on to an already initialized UDS1 DS1 board.
NOTE:
For the I-CSU only, the ELB test is also executed as part of the
command test ds1-loop UUCSS ds1/csu-loopback-tests. Attempt
to clear the alarm using the commands busyout board UUCSS, test
ds1-loop UUCSS ds1/csu-loopback-tests, release board UUCSS.
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) has failed. Attempt 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. 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 is already installed)
or when the 120A1 CSU module is plugged on to an already initialized DS1
board.
NOTE:
For the I-CSU only, the RLB test is also executed as part of the
command test ds1-loop UUCSS ds1/csu-loopback-tests. Attempt
to clear the alarm using the commands busyout board UUCSS, test
ds1-loop UUCSS ds1/csu-loopback-tests, release board UUCSS.
If the RLB test continues to fail, then the CSU module needs to be
replaced.
q. Error Type 1313 — CPE Loop-Back Jack deactivation error. This error
occurs when the UDS1 circuit pack could not deactivate a CPE Loop-Back
Jack on power-up/reset or upon software request.
Attempt to clear the alarm using the commands busyout board UUCSS,
test ds1-loopback UUCSS end-loopback/span-test, release board
UUCSS. If the attempt to deactivate the CPE Loop-Back 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
loop back on power-up/reset or upon software request.
Attempt to clear the alarm using the commands busyout board UUCSS,
test ds1-loop UUCSS end-loopback/span-test, release board UUCSS.
If the attempt to deactivate the Far CSU loop back continues to fail, then
escalate the problem.
