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.
If the 402A or 403A E1 Synchronization 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 E1 Sync-Splitter? field
to n.
n. Error Type 1310 — BLB failure. This error occurs when the DS1 Board
Loopback (BLB) demand test fails. Repeat the test using the commands
busyout board UUCSS, test ds1-loop UUCSS ds1/csu-loopback-tests,
release board UUCSS. If the BLB test continues to fail, then the TN464F
circuit pack needs to be replaced.
o. Error Type 1311 — ELB failure. This error occurs when the Equipment
Loopback (ELB) test fails for the Integrated CSU (I-CSU) Module/T1 Sync
Splitter or for the 402A or 403A E1 Synchronization Splitter. This test is
executed by the I-CSU/E1SS during I-CSU/E1SS power-up/reset (i.e.-
UDS1 board physically inserted and 120A1 CSU Module or the 401A T1
Sync Splitter, or the 402A or 403A E1SS is already installed) or when the
120A1 CSU Module or the 401A T1 Sync Splitter, or the 402A or 403A
E1SS is plugged on to an already initialized UDS1 DS1 board.

Issue 5 October 2002
NOTE:
For the I-CSU/T1 Sync Splitter only, the ELB test is also executed
as part of the command test ds1-loop UUCSS
ds1/csu-loopback-tests. Attempt to clear the alarm using the
commands busyout board UUCSS, test ds1-loop UUCSS
ds1/csu-loopback-tests, release board UUCSS. If the ELB test
continues to fail, then either the UDS1 board, the CSU Module, or the
I/O cable between the backplane and the CSU module (or any
combination thereof) has failed. Attempt to isolate where the failure is
occurring by re-executing the test and by replacing one piece of
hardware at a time.
