Maintenance Object Repair Procedure
j. Error Type 1300 — CSU module missing.
CSU module: The Near-End CSU Type field on the add ds1 form has
been administered as integrated but the 120A1 CSU module is not
physically connected (or is improperly connected) to the UDS1 board
behind the port carrier.
If using the 120A1 CSU module, plug (or replug) the CSU module into the
UDS1 circuit pack's connector on the I/O connector panel on back of the
carrier. Otherwise, change the Near-End CSU Type field using the
change ds1 form to other.
If this error remains after plugging the CSU module into the board's
connector, there could be a problem with the I/O connector panel.
k. Error Type 1301 — CSU module not expected.
CSU Module not expected: The 120A1 CSU module is physically
connected to the UDS1 board behind the port carrier, but the Near-End
CSU Type field on the add ds1 form has not been administered as
integrated.
If the 120A1 CSU module is to be used, use the change ds1 command to
change the Near-End CSU Type field to integrated. Otherwise,
physically remove the 120A1 CSU module from the back of the port carrier.
l. Error Type 1302 — DS1 configuration error. Attempting to use the 120A1
CSU module with a UDS1 circuit pack that is configured for 32-channel
(2.048-Mbps) operation. The CSU module only works with a DS1 board
configured for 24-channel (1.544-Mbps) operation in the United States of
America.
m. Error Type 1303 — DS1 circuit pack suffix incorrect for CSU module.
DS1 circuit pack suffix incorrect for CSU module: The Near-End CSU
Type field on the add ds1 form has been administered as integrated
but the DS1 circuit pack is not a TN464F or later suffix UDS1 board.
If the 120A1 CSU module is to be used, remove the circuit pack and
replace it with a TN464F or later suffix board. Otherwise, use the change
ds1 command to change the Near-End CSU Type field to other.
n. Error Type 1310 — BLB failure. This error occurs when the DS1 Board
Loopback (BLB) demand test fails. Repeat the test using the commands
busyout board UUCSS, test ds1-loop UUCSS ds1/csu-loopback-tests,
release board UUCSS. If the BLB test continues to fail, then the TN464F
circuit pack needs to be replaced.
