Code Result Description / Recommendation
1311 FAIL The Integrated CSU (I-CSU) Module Equipment Loopback (ELB) test (#1210)
failed. This test is executedduring ICSU
TN767E board is physically inserted and the CSU module
already installed) or when the 120A CSU module
on to an already initialized DS1 board. The ELB test is also executed as part of
the command test ds1-loop UUCSS ds1/csu-loopback-tests.
1. Execute test ds1-loop UUCSS ds1/csu-loopback-tests.
2. If the ELB test continues to fail, then either the TN767E board, the CSU
3. If the ELB test continues to fail, then replace the TN767E board and run
4. If the ELB test continues to fail, the problem could be in the I/O cable
1312 FAIL The Integrated CSU (I-CSU) Module Repeater Loopback (RLB) test (#1211)
failed. This test is executed during ICSU
TN767E board is physically inserted and the CSU module
already installed), or when the 120A1 CSU module
on to an already initialized DS1 board. The RLB test is also executed as part of
the command test ds1-loop UUCSS ds1/csu-loopback-tests.
1. Execute test ds1-loop UUCSS ds1/csu-loopback-tests.
2. If the RLB test continues to fail, then replace the CSU module
3. Run this test again.
1313 FAIL The TN767E circuit pack could not deactivate a CPE loop-back jack loop back.
1. Execute test ds1-loop UUCSS end-loopback/span-test.
2. If the attempt to deactivate the CPE loop-back jack is not successful, check
3. Run the test again.
1314 FAIL The TN767E circuit pack could not deactivate a far-end CSU loop loop-back.
1. Execute test ds1-loop UUCSS end-loopback/span-test.
