Battery Feed Test (also called Port Diagnostic
Test) (#35)
The battery feed chip provides power to the telep hone equipment, sig naling, rotary dial pulsing, transmission, and balanc e. This test checks the sig naling and switchhook capab ilities of the battery feed c hip by terminating t he 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 unrelia ble connections.
1. Issue the display port and the status station commands to determine
if the station is idle. If the station is idle, issue the test port command for
this port.
2. If the test continues to fail, issue the busyout port and the release port
commands, and then retest.
3. If the test still fails, replace the board.
PASS The port can correctly conference multiple connec tions. User-reported
troubles on this port should be investigated by using other p ort tests and by
examining station, trunk, or ex te rnal 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 b oard is
inserted, or an insane board is inserted.
1. Check to ensure that the board 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- e stablish 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.
