m. ELB failure. This error occurs when the Integrated CSU (I-CSU) Module
Equipment Loopbac k (ELB) test fails. This test is executed during
I-CSU/T1 Sync Splitter power-up/reset (i.e., the TN767E board is
physically inserted and the CSU Module/T1 Sync Splitter is already
installed) or when the CSU Module/T1 Sync Splitter is plug ged on to an
already initialized DS1 board. The ELB test is also executed as part of the
command test ds1-loop UUCSS ds1/csu-loopback-tests.
Attempt to clear the alarm via the follo wing commands: busyout board
UUCSS, test ds1-loop UUCSS ds1/csu-loopback-tests, and release
board UUCSS. If the ELB test continues to fail, then either the TN767E
board, the CSU Module, the T1 Sync Splitter, or the I/O c able between the
backplane and the CSU Module/T1 Sync Splitter (or any combination
thereof) has failed. Attempt to isolate where the failure is o ccurring by
re-executing the test. Escalate this p roblem.
n. RLB failure. This error occurs when the Integrated CSU (I-CSU) Module
Repeater Loopback (RLB) test fails. This test is ex ecuted during I-CSU/T1
Sync Splitter power-up/reset (i.e., the TN767E board is physically inserted
and the CSU Module/T1 Sync Splitter is already installed ) or when the
CSU Module/T1 Sync Splitter is plugged on to an already initialized DS1
board. The RLB test is also executed as p art of the command test
ds1-loop UUCSS ds1/csu-loopback-tests.
Attempt to clear the alarm via the follo wing commands: busyout board
UUCSS, test ds1-loop UUCSS ds1/csu-loopback-tests, and release
board UUCSS. If the RLB test continues to fail, then the CSU Module/T1
Sync Splitter needs to be replac ed.
o. CPE Loopback Jack deac tivation error. This error occurs when the
TN767E circuit pack could not deactivate a CPE Loopbac k Jack
loopback.
Attempt to clear the alarm via the follo wing commands: busyout board
UUCSS, test ds1-loop UUCSS end-loopback/span-test, and release
board UUCSS. If the attempt to deactiv ate the CPE Loopback Jack
loopback c ontinues to fail, other steps must be taken to deactivate the
loopback.
p. Far CSU Loopback deac tivation error. This error occurs when the TN767E
circuit pack c ould not deactivate a far -end CSU loopback on
power-up/reset or upon software request.
Attempt to clear the alarm via the follo wing commands:
busyout board
UUCSS
,
test ds1-loop UUCSS end-loopb ack/span-test
,
release board
UUCSS
. If the attempt to deactivate the Far CSU loopback continues to
fail, then escalate the problem.
q. The hyperactive circ uit pack is out-of-servic e and may exhibit one or more
of the following symptoms:
1. The common circuit pac k level tests such as Test #51 and/or Test
#220 are aborting with error cod e 2000.
