1300 FAIL The CSU Module is 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 to the TN767E board on the back of the port carrier.
1. If using the 120A1 CSU Module, plug 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
.
2. Run the test again.
1301 FAIL 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
.
1. 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.
2. Run the test again.
1302 FAIL 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.
1. If the 120A1 CSU Module is to be used, physically remove the TN767E
circuit pack and reconfigure for 24-channel (1.544 Mbps) operation.
2. Reinsert the circuit pack and run the test again.
1303 FAIL The DS1 circuit pack Suffix is incorrect for CSU Module administration. 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.
1. If the CSU Module is to be used, and the
Near-End CSU
Type field is set
to
integrated
, to allow for CSU module administration, 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
.
1310 FAIL The DS1 Board Loopback (BLB) demand test (#1209) failed.
1. Repeat the test using the
test ds1-loop PCSS ds1/csu-loopback-tests
command.
2. If the BLB test continues to fail, then replace the TN767E circuit pack.
3. Run this test again.
