1028 Maintenance Procedures for Avaya Communication Manager 3.0, Media Gateways and Servers
The DS1 circuit pack hardware applies a DC current while the test is running in order to detect
any broken wires that may not be detected by the loop-back pattern.
When the test is complete, use release board to restore all trunks or ports on the TN767E
DS1 Interface circuit pack to the in-service state.

ABRT Internal system error
1. Retry test ds1-loop location ds1/csu-loopback-tests at
1-minute intervals up to 5 times.
1005 ABRT CSU Equipment Loopback test cannot be executed in the current
configuration. To run this test, the Near-End CSU Type field on the DS1
circuit pack administration screen must be set to integrated and the Bit
Rate field must be set to “1.544” (for 24-channel operation).
1. Use change ds1 location and set the Near-End CSU Type field
on the DS1 circuit pack administration screen to integrated, and/or set
the Bit Rate field to 1.544 if the board is to be used in a 24-channel
configuration.
2. Retry test ds1-loop location ds1/csu-loopback-tests.
1015 ABRT Ports on the DS1 Interface circuit pack have not been busied out to
out-of-service.
1. Enter busyout board location to put all trunks or ports of the
DS1 Interface circuit pack into the out-of-service state.
2. Retry the command.
1039 ABRT The DS1 Interface circuit pack is providing timing for the system. Executing
this test could cause major system disruption.
If the DS1 Interface circuit pack needs to be tested, set the synchronization
reference to another DS1 Interface circuit pack or to the Tone-Clock circuit
via the following command sequence:
1. Enter disable synchronization-switch.
2. Enter enable synchronization-switch set
synchronization location.
3. Enter enable synchronization-switch.
