BRI-PORT (ISDN-BRI Port), ABRI-PORT (ASAI
ISDN-BRI Port)
Electronic Power Feed Restoral Test (#620)
This test attempts to restore the Electronic Power Feed (EPF) on an ISDN-BRI
port twice. In this test, the processor requests that the EPF be turned on for a
given port. An attempt is made to turn on the power unit to the station or adjunct.
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.

Error Test
Code 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 1-minute intervals up to 5 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.

damaged jack, a defective voice terminal or adjunct, or an incorrect type of
terminal.
