Battery Feed Test (also called 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.
Any FAIL The NPE of the tested port did not conference the tones correctly. This will
cause noisy and unreliable connections.
1. Use display port and status station to determine if the station is idle. If
the station is idle, issue test port for this port.
2. If the test continues to fail, use busyout port and release port, and
retest.
3. If the test still fails, replace the board.
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.
0 NO
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. Check to ensure that the board translations are correct. Use list config
and resolve any problems.
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, check to ensure that there
is a valid board inserted.
