DIOD-DS1 (DS1 DIOD Trunk)
Issue 5 October 2002
1049
555-233-119
The DS1 interface circuit pack detects a hardware error on the DS1 DIOD
trunk. The trunk can not communicate with the far-end because it is unable
to interpret digits sent from the far-end switch. Check with the far-end
switch or Operating Company for proper trunk connection.
k. Error Type 2305—Recorder message, trunk could not be seized (Aux Data
50944). Run Test #314 and follow the outlined procedures.
l. Error Type 2562—Retry Failure error. This error is logged only. It is not a
hardware failure and hence does not start any testing or generate any
alarms. This error comes from call processing and is generated when a
second attempt (retry) to seize an outgoing trunk fails.
m. Error Type 2817—Glare error. This error is logged only. It is not a hardware
failure and hence does not start any testing or generate any alarms. This
error is the result of a simultaneous seizure of a two-way trunk from both
the near-end and the far-end. Attempt to place the call again. If the error
persists, execute the Dial Tone Seizure Test (#314) and follow those
procedures.
n. Error Type 3840—Port Audit and Update Test (#36) failed due to an
internal system error. Enter the status trunk command to verify the status
of the trunk. If the trunk is out-of-service, then enter the release trunk
command to put it back into in-service. Retry the test command.
System Technician-Demanded Tests: Descriptions
and Error Codes
Always investigate tests in the order they are presented in the table below when
inspecting errors in the system. By clearing error codes associated with the NPE
Crosstalk Test, for example, you may also clear errors generated from other tests
in the testing sequence.
