MEDPROPT (TN802/TN2302 MED PRO DSP PORT)
TDM NIC Loop-Around Test (#1380)
This test is nondestructive
This test sets up a loop-back path from the TDM bus out to the NIC edge of the
Media Processor and back to the TDM bus. The loop back is established by
setting up the outbound IP connection to send IP packets to the MedPro's own IP
address. The tone generator places a test tone (440Hz) onto a timeslot. The
timeslot is listened to by the Media Processor board. The tone is routed through
the TAP802/2302 DSP farm, where it may undergo transcoding to G.723, etc.
The tone is looped back at the Network interface and back through the
TAP802/2302 where it is converted back into standard PCM. The tone is placed
onto a TDM timeslot and detected by a tone detector port. The test passes if
440Hz is reported by the tone detector

Error Test
Code Result Description / Recommendation
1002 ABORT The system could not allocate timeslots for the test. The system may be under
heavy traffic conditions, or it may have timeslots out of service due to
TDM-BUS errors.
1. If the system has no TDM-BUS errors and is not handling heavy traffic,
2. If the system has TDM-BUS errors, clear any errors, and retry the
3. If the command continues to abort, escalate the problem.
1003 ABORT The system could not allocate a tone receiver for the test. The system may be
oversized for the number of Tone Detectors present, or some Tone Detectors
may be out of service.
1. Resolve any TTR-LEV errors. Even if there are no TTR-LEV errors, there
2. Resolve any TONE-PT errors.
3. If neither condition exists, retry the command at 1-minute intervals up to 3
2000 ABORT Response to the test was not received in the allowable time period.
1. Retry the command at 1-minute intervals up to 3 times.
