DS1 circuit pack suffix incorrect for E1 synchronization splitter: The E1 Sync-Splitter
field on the add ds1 screen is set to y but the DS1 circuit pack is not a TN464F or higher
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 higher suffix board. Otherwise, use change ds1 to set 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 busyout board location, test ds1-loop
location ds1/csu-loopback-tests, release board location. If the BLB test
continues to fail, replace the TN464F circuit pack.
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, the 401A T1
sync splitter, or the 402A or 403A E1SS is already installed) or when the 120A1 CSU
module, the 401A T1 sync splitter, or the 402A or 403A E1SS is plugged on to an already
initialized UDS1 DS1 board.
Note:
Note: For the I-CSU/T1 sync splitter only, the ELB test is also executed as part of
test ds1-loop location ds1/csu-loopback-tests. Try to clear the
alarm using busyout board location, test ds1-loop location ds1/
csu-loopback-tests, and release board location. 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, failed.
Try to isolate where the failure is occurring by re-executing the test and by
replacing one piece of hardware at a time.
p. Error Type 1312: RLB failure. This error occurs when the Repeater Loopback (RLB) 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., DS1 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 DS1 board.
Note:
Note: For the I-CSU/T1 sync splitter only, the RLB test is also executed as part of the
test ds1-loop location ds1/csu-loopback-tests. Try to clear the
alarm using busyout board location, test ds1-loop location ds1/
csu-loopback-tests, and release board location. If the RLB test
continues to fail, replace the CSU module.
