If no current is being drawn by a station, this probably indicates that the station is
not connected. No current being drawn by an adjunct is the normal condition. If
an overcurrent condition is sensed (that is, too much current is being drawn), this
condition may indicate a short in the wiring to the endpoint or adjunct.
Depending on what condition is sensed, a message is returned stating that either
the EPF was turned on successfully with no problems or that an overcurrent
condition is sensed. This response is reported by the Electronic Power Feed
Inquiry (#622), which follows in the testing sequence. EPF Restoral is attempted
again by this test five seconds later. This test always passes for the TN2198
because it has no EPF. This test will always abort when run on the TN2208.

Test
Result Description / Recommendation
1005 ABORT This test is not valid for this port type. The TN2208 does
not have an electronic power feed, and the test will
abort.
2012 ABORT Internal System Error.
1. Retry the command at one-minute intervals a
maximum of five times.
2. If the test continues to abort, escalate the problem.
PASS The EPF Test passed. The message to turn on the
power feed to the station or the adjunct was
successfully sent to the port.
1. Although this test should not return a fail result, after
running this test, the Error Log should be checked
for any entries with error type 257 to examine the
real results of this test.
2. An error type of 257 in the Error Log indicates some
problem with the power to the station or the adjunct.
Check for a short in the wiring, a damaged jack, a
defective voice terminal or adjunct, or an incorrect
type of terminal.
