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.
Level 1 Status Inquiry Test (#621)
This test determines the state of the transmission facility of a BRI port at the
physical layer (that is, Level 1). Level 1 can be in one of three possible states:
Activated, Pending Activation, or Deactivated.
The Activated state is the correct state for an ISDN-BRI port. In this state the
Level 1 interface can communicate with the BRI endpoint or ASAI or Avaya
adjunct administered on this port. This test passes if the state of Level 1 (L1) is
Activated. This test also passes if software has taken this port out of service. See
the description of the Level 1 “Deactivated State” below for more details.

Error
Code 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 1-minute intervals a maximum of 5 times.
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.
