Communication Manager Maintenance-Object Repair Procedures
1106 Maintenance Procedures for Avaya Communication Manager 3.0, Media Gateways and Servers
Every part of this test is executed under firmware control and the result is sent back to the
maintenance software. The test is executed by sending digital data through every DS1 facility
channel. Two different test patterns are used, these are hexadecimal values 55 and AA.
For a standard-, duplex-, or high-reliability system (no PNC duplication), this test can only be
executed at the endpoint that is closer to the media server relative to the neighbor DS1
converter circuit pack because of its impacts on the system control links, also the completion of
the test will be delayed in this configuration to wait for the recovery of the system control links.
For a critical-reliability system (PNC duplication), the test can be executed at any DS1 converter
circuit pack.

Description / Recommendation
1410 ABRT The test aborted because no lightwave transceiver is present. The neighbor
DS1 converter circuit pack and the fiber endpoint are connected via metallic
cable. This abort may be ignored.
2000 ABRT Timed out while waiting for a response from the circuit pack.
1. Retry the command at 1-minute intervals up to 3 times.
2100 ABRT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 3 times.
