Loop Around and Conference Test (#47)

Each Analog Port consists of:
an NPE for port connectivity and gain, and conferencing functionality
a code that converts the digital signals of the TDM Bus to analog signals
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 code, 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 instructed to go into loop around mode (see
test passes if the signal measured by the Tone Detector is within acceptable
limits.

Description/ Recommendation
This does not indicate a hardware problem but may be an internal software
error. The ringer update failed.
1. Retry the command at 1-minute intervals a maximum of 5 times.
The software and the port processor have the same status. User-reported
troubles on this port should be investigated by using other port tests, by
examining station wiring, by examining the station, and by ensuring that the
terminal is correctly translated as off-premises or on-premises.
NOTE:
This test always passes for TN742 Analog circuit packs prior to
Vintage 6.
The test could not relate the internal ID to the port (no board). This could be
due to incorrect translations, no board is inserted, an incorrect board is
inserted, or an insane board is inserted.
1. Check to ensure that the board translations are correct. Use list config
and resolve any problems that are found.
2. If the board was found to be correctly inserted in step 1, Use busyout
board.
3. Issue reset board.
4. Issue release busy board.
5. Issue test board long. This should re-establish the linkage between
the internal ID and the port. If this is not the case, dispatch to check to
ensure that there is a valid board inserted.
