DS1-BD (DS1 Interface Circuit Pack)
j. Error Type 1301: CSU module/T1 sync splitter not expected. The 120A CSU or T1 sync
splitter is physically connected to the TN767E board on the back of the port carrier, but the
Near-End CSU Type field on the add ds1 screen has not been administered as
integrated.
If the 120A CSU or T1 sync splitter is to be used, use change ds1 to change the
Near-End CSU Type field to integrated. Otherwise, physically remove the 120A CSU
or T1 sync splitter from the back of the port carrier.
k. Error Type 1302: DS1 configuration error. Attempting to use a 120A CSU with a TN767E
circuit pack that is configured for 32-chel (2.048-Mbps) operation. This CSU only works with
a DS1 board configured for 24-chel (1.544-Mbps) operation in the United States of America.
l. Error Type 1303: DS1 circuit pack suffix incorrect for CSU or T1 sync splitter. The
Near-End CSU Type field on the add ds1 screen has been administered as
integrated but the DS1 circuit pack is not a TN767E (or higher-suffixed) DS1 board.
If the 120A CSU or T1 sync splitter is to be used, remove the circuit pack and replace it
with a TN767E (or higher-suffixed) board. Otherwise, use change ds1 to change the
Near-End CSU Type field to other.
m. Error Type 1310: BLB failure. This error occurs when the DS1 Board Loopback (BLB)
demand test fails. Repeat the test using busyout board location, test ds1-loop
location ds1/csu-loopback-tests, release board location. If the BLB test
continues to fail, then the TN767E circuit pack needs to be replaced.
n. Error Type 1311: ELB failure. This error occurs when the Integrated CSU (I-CSU) Module
Equipment Loopback (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 plugged on to an
already initialized DS1 board. The ELB test is also executed as part of test ds1-loop
location ds1/csu-loopback-tests.
Attempt to clear the alarm with 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 TN767E board, the CSU module, the T1 sync splitter,
or the I/O cable between the backplane and the CSU module/T1 sync splitter (or any
combination thereof) has failed. Escalate this problem.
o. Error Type 1312: RLB failure. This error occurs when the Integrated CSU (I-CSU) Module
Repeater Loopback (RLB) 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 plugged on to an
already initialized DS1 board. The RLB test is also executed as part of the command test
ds1-loop location ds1/csu-loopback-tests.
Attempt to clear the alarm with busyout board location, test ds1-loop
location ds1/csu-loopback-tests, and release board location. If the RLB
test continues to fail, then the CSU module/T1 sync splitter needs to be replaced.
