Error Test
Code Result Description / Recommendation
0 NO The test could not relate the internal ID to the port (no board). This could be
BOARD due to incorrect translations, no board is inserted, an incorrect board is
inserted, or an insane board is inserted.
1. Verify that the board's translations are correct. Use the list config
2. If the board was found to be correctly inserted in step 1, issue the busyout
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board long command.
Looparound and Conference Test (#47)
Each Analog port consists of:
An NPE (Network Processing Element) for port connectivity and gain, and
conferencing functionality
A codec that converts TDM Bus digital signals to analog
A battery feed chip that provides power to the telephone set for signaling,
dial pulsing, transmission, and balance.
This test is designed to check the on-board transmission capabilities of the NPE,
the codec, and the battery feed chip of the Analog port. A Tone Detector and a
Tone Generator talk and listen on the same pair of time slots as the Analog port.
The Analog port is then instructed to go into loop around mode (see
page 8-93). The test passes if the signal measured by the Tone Detector is within
acceptable limits.
The Conference Circuit test verifies that the NPE channel for the port being tested
can correctly perform the conferencing function. Test #47 also tests the operation
of the port conference circuits in the NPE for three and four parties. In addition, a
test is run to measure noise. The NPE is instructed to listen to several different
tones and conference the tones together. The resulting signal is then measured
by a Tone Detector port. If the level of the tone is within a certain range, the test
passes.

This should re-establish the linkage between the internal ID and the port. If
not, dispatch to verify that a valid board is inserted.
