DS1-BD (DS1 Interface Circuit Pack)
Issue 1 June 2005 999
1300 FAIL The CSU module or the T1 sync splitter is missing. The Near-End CSU
Type field on the add ds1 screen has been administered as integrated,
but the 120A1 CSU module/T1 sync splitter is not physically connected to
the TN767E board on the back of the port carrier.
1. If using the 120A1 CSU module/T1 sync splitter, plug the CSU module/
T1 sync splitter into the TN767E circuit pack’s connector on the I/O
connector panel on back of the carrier. Otherwise, set the Near-End
CSU Type field using the change ds1 screen to other.
2. Run the test again.
1301 FAIL The 120A1 CSU module or the 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 is not administered as integrated.
1. If the 120A1 CSU module/T1 sync splitter is to be used, use change
ds1 to change the Near-End CSU Type field to integrated.
Otherwise, physically remove the 120A1 CSU module/T1 sync splitter
from the back of the port carrier.
2. Run the test again.
1302 FAIL Attempting to use a 120A1 CSU module with a TN767E circuit pack that is
configured for 32-channel (2.048-Mbps) operation. This CSU 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 is to be used, physically remove the TN767E circuit
pack, and reconfigure it for 24-channel (1.544-Mbps) operation.
2. Reinsert the circuit pack, and run the test again.
1303 FAIL The DS1 circuit pack’s suffix is incorrect for CSU module/T1 sync splitter
administration. 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.
1. If the CSU module or the T1 sync splitter is to be used, and the
Near-End CSU Type field is set to integrated to allow for CSU
module/T1 sync splitter administration, remove the circuit pack and
replace it with a TN767E (or higher-suffixed) board. Otherwise, use
change ds1 to set the Near-End CSU Type field to other.
