are detected for 30 minutes. The value in the Aux Da ta field indicates the
type of hardware problem. Ho wever, when this error is reported with Aux
Data in the range of 4352 to 4358, it indic ates the circuit pac k has
reported a hardware failure suc h that the circuit pac k should be replac ed.
g. The DS1 Interface circuit pack has detected a transient hard ware logic
error (for example, program log ic inconsistency). This error will dis appear
when no faults are detected for 100 minutes. The value in Aux Data field
indicates the type of hard ware 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 connec ted (or is improperl y connected) to the TN767E
board on the bac k of the port carrier.
If using the 120A1 CSU Module, plug (or rep lug) the CSU Module into the
TN767E circuit pack’s connec tor on the I/O connector p anel 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 c onnector panel.
i. CSU Module not expected. The 120A1 CSU Module is p hysically
connected to the TN767E board on the back of the port c arrier 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, us e the change ds1 command to
change the Near-End CSU Type field to integrated. Othe rwise,
physically remove the 120A1 CSU Module from the b ack of the port
carrier.
j. DS1 configuration error. Attempting to use the 120A 1 CSU Module with a
TN767E circuit pack that is confi gured for 32-channel (2.048 Mb ps)
operation. The CSU Module only works with a DS1 board c onfigured for
24-channel (1.544 Mbps) op eration in the United States of America.
k. DS1 circuit pack suffix incorrec t for CSU Module. The Near-End CSU
Type field on the add ds1 form has been ad ministered as integrated
but the DS1 circuit pac k is not a TN767E or later suffix DS1 board.
If the 120A1 CSU Module is to be used, remove the c ircuit pack and
replace it with a TN767E or later suffix board. Otherwise, u se the change
ds1 command to chang e the Near-End CSU Type field to other
.
l. BLB failure. This error occurs when the DS1 Board Loopbac k (BLB)
demand test fails. Repeat the test using the following command s:
busyout board UUCSS, test ds1-loop UUCSS ds1/csu-loopback-tests,
release board UUCSS. If the BLB test continues to fail, then the TN767E
circuit pack need s to be replaced .
m. ELB failure. This error occurs when the Integrated CSU (I-CSU) Module
Equipment Loopbac k (ELB) test fails. This test is executed by the I-CSU
during I-CSU power-up/reset (i.e., TN767E board physically inserted and
