CO-TRK (CO Trunk)
Issue 4 May 2002
10-451 555-233-123
57481 FAIL On-board test of programmable transmission circuitry failed.
1. Replace the circuit pack.
PASS This test verifies that the port is able to apply ground for
outgoing calls and detect ground for incoming calls; however, it
does not provide information on whether a CO line is actually
connected. User-reported troubles on this port should be
investigated by using other port tests and by examining trunk or
external wiring.
0NO
BOARD
The test could not relate the internal ID to the port (no board).
1. Check to ensure that the board translations are correct.
Translate the board, if necessary.
2. Issue the busyout board command.
3. Issue the reset board command.
4. Issue the release busy board command.
5. Issue the test board command. This should re-establish
the linkage between the internal ID and the port.
