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 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 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
1-11 FAIL Some DSPs on the circuit pack have failed. The FAIL code is the number of
bad DSPs reported.
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.
