2446 Maintenance Procedures for Avaya Communication Manager 3.0, Media Gateways and Servers
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.

ABRT Internal system error
1. Retry test ds1-loop location ds1/csu-loopback-tests at
1-minute intervals up to 5 times.
1005 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.
1015 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.
1039 ABRT 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.
