Avaya 03-300430 User Manual

When the BLB test is initiated, maintenance software sends an appropriate message to the 
UDS1 Interface circuit pack to start the test. The board sets up the BLB loopback, transmits a 
test pattern, and verifies that the pattern is received unaltered through the loopback. If the 
transmitted and received pattern is different, the test fails.
When the test is complete, each trunk or port on the TN464GP/TN2464BPTN UDS1 Interface 
circuit pack is restored to the in-service state after release board location is entered.

1. Retry test ds1-loop location ds1/csu-loopback-tests at 

1-minute intervals up to 5 times.

ABRT

UDS1 Board Loopback test cannot be executed in the current 

configuration. To run this, the TN464F or higher suffix UDS1 must be 

administered for 24-channel operation. The “Bit Rate” field on the DS1 

circuit pack administration screen must be set to “1.544” for 24-channel 

operation.

ABRT

Ports on the UDS1 Interface circuit pack have not been busied out to 
out-of-service.

1. Enter busyout board location to put every trunk or port of the 

UDS1 Interface circuit pack into the out-of-service state.

2. Retry the command.

The UDS1 Interface circuit pack is providing timing for the system. 

Executing this test could cause major system disruption.
If the UDS1 Interface circuit pack needs to be tested, set the 
synchronization reference to another DS1 Interface circuit pack or to the 
IPSI or Tone-Clock circuit pack via the following command sequence: 

1. Enter disable synchronization-switch.
2. Enter set synchronization location.
3. Enter enable synchronization-switch.

Rerun the test. If the test aborts again, a different ABRT Error Code will be 

generated. Follow the recommended maintenance procedures for that 

Error Code.
