Hybrid Electronic Power Feed Test (#56)

In this test, the software requests that the EPF be turned on for a given por t. Then

hardware attempts to turn on the po wer unit from the station. If no current is

drawn, the station is probab ly not connected . If an overcurrent condition is

2020 ABORT The test did not run due to an already existing error on the specific port or a
more general circuit pack error.
1. Examine Error Log for existing errors against this port or the circuit pack
and attempt to diagnose the already existing error.
2100 ABORT Could not allocate the necessary system resources to run this test. This could
be due to a failure to seize the port.
1. Retry the command at 1-minute intervals a maximum of 5 times.
Any FAIL This test can fail due to on-boa rd or off-board p roblems. Off-board problems of
concern include EXP-PN and EXP-INTF faults, TDM-BUS faults, and faults
associated with the tone detectors/tone generators. Clear all off-board
problems before replacing the b oard. Keep in mind that a TDM-BUS problem is
usually the result of a faulty board connected to the backplane or bent p ins on
the backplane.
1. Resolve any “EXP-PN” and “EXP-INTF” errors in the error log.
2. Resolve any “TDM-BUS” errors in the error log.
3. Retest the board when the faults from steps 1 and 2 are cleared.
PASS The port is correctly using its allocated time slots. User-reported troubles on this
port should be investigated 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. Check to ensure that the board translations are correct. Use the list config
command, and resolve any problems that are found.
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 this is not the case, dispatch to
check to ensure that there is a valid board inserted.
