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.

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 2-way trunk from both the near and far ends. Attempt to place the call again. If the error persists, execute the Dial Tone Seizure test (#314), and follow those procedures.

Error type 3840: Port Audit and Update test (#36) failed due to an internal system error. Enter status trunk to verify the status of the trunk. If the trunk is out-of-service, then enter release trunk to put it back into in-service. Retry the test command.
