UDS1-BD (UDS1 Interface Circuit Pack)
Issue 4 May 2002
10-1849 555-233-123
If using the 402A or 403A E1 Synchronization Splitter, plug (or replug) the
E1SS into the UDS1 circuit pack’s connector on the I/O connector panel on
back of the carrier. Otherwise, change the E1 Sync-Splitter? field
using the change ds1 form to n.
If this error remains after plugging the E1SS into the board’s connector,
there could be a problem with the I/O connector panel.
k. Error Type 1301 — CSU Module/T1 Sync Splitter not expected or E1
Synchronization Splitter not expected.
CSU Module/T1 Sync Splitter not expected: The 120A1 CSU Module or
the 401A T1 Sync Splitter is physically connected to the UDS1 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 or the 401A T1 Sync Splitter 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 or the
401A T1 Sync Splitter from the back of the port carrier.
E1 Synchronization Splitter not expected: The 402A or 403A E1
Synchronization Splitter is physically connected to the UDS1 board on the
back of the port carrier but the E1 Sync-Splitter? field on the add ds1
form has not been administered as y.
If the 402A or 403A E1 Synchronization Splitter is to be used, use the
change ds1 command to change the E1 Sync-Splitter? field to y.
Otherwise, physically remove the 402A or 403A E1 Synchronization
Splitter 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/T1
Sync Splitter or for E1 Synchronization Splitter.
DS1 circuit pack suffix incorrect for CSU Module/T1 Sync Splitter: 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 or the 401A T1 Sync Splitter 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.
DS1 circuit pack suffix incorrect for E1 Synchronization Splitter: The
E1 Sync-Splitter? field on the add ds1 form has been administered
as y but the DS1 circuit pack is not a TN464F or later suffix UDS1 board.
