Battery Feed Test (or Port Diagnostic Test) (#35)
The battery feed chip provides power to the telephone equipment, signaling,
rotary dial pulsing, transmission, and balance. This test checks the signaling and
switchhook capabilities of the battery feed chip by terminating the port, applying
battery and detecting the resulting current.
For the TN746B, Test #35 does not actually run and instead always returns PASS.
Test #35 operates in the normal manner for TN746.
PASS The port can correctly conference multiple connections. User-reported troubles
on this port should be investigated by using other port tests and by examining
station, trunk, or external wiring.
0NO
BOARD
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. Verify that the board’s translations are correct. Use the list config
command, and resolve any problems.
2. If the board was found to be correctly inserted in step 1, issue the busyout
board command.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board long command.
This should re-establish the linkage between the internal ID and the port. If
not, verify that a valid board is inserted.
