TDM NIC Looparound Test (#1380)
This test is non-destructive
This test sets up a loopback path from the TDM bus out to the NIC edge of the
Media Processor and back to the TDM bus. The loopback 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

Result Description/Recommendation
2000 ABORT Response to the test was not received within the allowable time period.
1. Retry the command at 1-minute intervals a maximum of 3 times.
2100 ABORT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals a maximum of 3 times.
2500 ABORT Internal system error
1. Retry the command at 1-minute intervals a maximum of 3 times.
1-11 FAIL Some DSPs on the circuit pack have failed. The FAIL code is the number of
bad DSPs reported (TN802B only).
FAIL For the TN2302 only, the DSP failed. If it continues to fail, it will be taken out
of service.
PASS All 11 DSPs are functioning and in-service.
0NO
BOARD
No board was detected by the test.
1. Check the Error Log for wrong board (Error Type 125) or no board
(Error Type 131). Resolve either of these issues, if applicable.
2. Check that the board is properly translated and inserted. If so,
check for hyperactivity. If hyperactive, use the reset board UUCSS
command.
3. Run the test again. If it fails, the circuit pack may be bad. Replace
the circuit pack and retest.
