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.
2103 ABORT The system could not make the conference connection for the test.
1. Retry the command at one-minute intervals a maximum of five times.
2. If the test continues to abort, escalate the problem.
1, 2 FAIL As stated previously, this test runs a TDM Loop Around Test on each
B-channel. This indicates that the loop around failed on one of the
channels. Error Code 1 indicates that the TDM Loop Around Test failed on
B1. Error Code 2 indicates that the TDM Loop Around Test failed on B2.
7, 8 FAIL As stated previously, this test runs a Conference Circuit Test on each
B-channel. A failure here indicates that one of these conference tests
failed; Error Code 7 means that the test failed on B1; Error Code 8 means
that the test failed on B2.
1. If the test fails repeatedly, attempt to reset the circuit pack if the other
ports on the circuit pack are not in use. Reset the circuit pack by
issuing the busyout board PCSS and the reset board PCSS
commands.
2. If the test fails again, replace the circuit pack.
PASS The BRI Port Local TDM Loop Around Test has passed.
