1300 FAIL The CSU module/T1 sync splitter or the E1 Sync Splitter is missing.
The CSU module/T1 sync splitter is missing: The
Near-End CSU Type
field on the add ds1 form has been administered as
integrated but the
120A1 CSU module or the 401A T1 sync splitter is not physically connected to
the UDS1 board behind the port carrier.
1. If using the 120A1 CSU module or the 401A T1 sync splitter, plug the CSU
module/T1 sync splitter into the UDS1 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.
The E1 Sync Splitter is missing: The E1 Sync-Splitter? field on the add
ds1 form has been administered as
y but the 402A or 403A E1 Sync Splitter is
not physically connected to the UDS1 board behind the port carrier.
1. If using the 402A or 403A E1 synchronization splitter, plug 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.
2. Run the test again.
1301 FAIL The 120A1 CSU module or the 401A T1 sync splitter, or the 402A or 403A E1
synchronization splitter is not expected.
The 120A1 CSU module or the 401A T1 sync splitter is not expected: The
120A1 CSU module/T1 sync splitter is physically connected to the UDS1 board
behind 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/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/T1
sync splitter from the back of the port carrier.
2. Run the test again.
The 402A or 403A E1 synchronization splitter is not expected: The 402A or
403A E1 synchronization splitter is physically connected to the UDS1 board
behind the port carrier, but the
E1 Sync-Splitter? field on the add ds1
form has not been administered as
y.
1. 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.
2. Run the test again.
