are detected for 30 minutes. The value in the Aux Data field indicates the
type of hardware problem. However, when this error is reported with Aux
Data in the range of 4352 to 4358, it indicates the circuit pack has
reported a hardware failure such that the circuit pack should be replaced.
g. The DS1 Interface circuit pack has detected a transient hardware logic
error (for example, program logic inconsistency). This error will disappear
when no faults are detected for 100 minutes. The value in Aux Data field
indicates the type of hardware problem.
h. CSU Module missing. 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 TN767E
board on the back of the port carrier.
If using the 120A1 CSU Module, plug (or replug) the CSU Module into the
TN767E 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.
i. CSU Module not expected. The 120A1 CSU Module 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 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.
j. DS1 configuration error. Attempting to use the 120A1 CSU Module with a
TN767E 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.
k. 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 TN767E or later suffix DS1 board.
If the 120A1 CSU Module is to be used, remove the circuit pack and
replace it with a TN767E or later suffix board. Otherwise, use the change
ds1 command to change the Near-End CSU Type field to other
.
l. BLB failure. This error occurs when the DS1 Board Loopback (BLB)
demand test fails. Repeat the test using the following commands:
busyout board PCSS, test ds1-loop PCSS ds1/csu-loopback-tests,
release board PCSS. If the BLB test continues to fail, then the TN767E
circuit pack needs to be replaced.
m. ELB failure. This error occurs when the Integrated CSU (I-CSU) Module
Equipment Loopback (ELB) test fails. This test is executed by the I-CSU
during I-CSU power-up/reset (i.e., TN767E board physically inserted and
