555-233-123 10-576 Issue 4 May 2002
TN2181 and TN2224 boards carry a Protected Power Feed (PPF) relays, one for
each port. Therefore this will be a Protected Power Feed restore test. The test
procedure and its response is same as that of EPF. One of differences between
EFP and PPF is that, if the port goes into a overcurrent state, PPF does not report
this change of state because it is a transient state which will not last more than
50ms. If the over current persists the power will be shut off automatically and an
EPF_off_overcurrent message is sent uplink.

Result Description/Recommendation
ABORT Internal System Error
1. Retry the command at 1-minute intervals a maximum of 5
times.
1000 ABORT System resources required to run this test are not available.
The port may be busy with a valid call. Use display port
PCSSpp to determine the station extension or attendant
number of the port. Use status station or status attendant to
determine the service state of the port. If the service state
indicates that the port is in use, then the port is unavailable for
certain tests. You must wait until the port is idle before
retesting. Attendants are always in use (off-hook) if the
handset is plugged in and the port is not busied out.
1. If the port status is idle, then retry the command at
1-minute intervals a maximum of 5 times.
FAIL Internal System Error
1. Retry the command at 1-minute intervals a maximum of 5
times.
PASS Electronic Power Feed Test passed. The message to turn on
the power to the station was successfully sent to the port.
1. Although this test will never actually return a FAIL result
except for the Internal System Error (naught/FAIL)
described above, it will log an error indicating the real
results of the test. Check the Error Log for any entries with
Error Types 767 or 769 after the test completes.
2. If Error Type 767 appears in the Error Log, this should
indicate that the test sensed no problems with the power to
the station. To verify that the station is powered up
correctly, run a self-test on the station, if available, and
check that all the feature buttons are operating.
3. If Error Type 769 appears in the Error Log, this indicates
some problem with the power to the station. Check for a
short in the wiring, a damaged jack, a defective voice
terminal, or an incorrect type of terminal.
