wire from the jack to the switch). If the problem still exists, replace the
circuit pack. Once the problem has been resolved, the alarm will be
retired after a predetermined amount of time.
b. This Error Type and Aux Data will occur when at least 15 off-board
problems have been detected with the link to the terminal. When an error
with the link is detected, an on-board counter is incremented.
The user could experience a noisy port or link. This is an off-board
problem detected by the port circuit. Check for defective wiring, a
defective voice terminal, or move voice terminal closer to the switch (in
terms of feet of wire from the jack to the switch). If the problem still exists,
replace the circuit pack. Once the problem has been resolved, the alarm
will be retired after a predetermined amount of time.
c. This error type is logged when the port in question is busied out by
maintenance personnel. Make sure port is released from busyout via the
release port PCSSpp command.
d. This error type indicates that the circuit pack has been removed or has
been insane for more than 21 minutes. To clear the error, reinsert or
replace the circuit pack.
e. Problems transmitting to the voice terminal. This problem can be caused
by defective wiring. Defective wiring can cause varying degrees of
problems on different types of sets. Sets such as the 7410 appear to be
more susceptible to wiring problems than other sets. This is usually an
on-board problem and can be ignored if no user complaints are received.
f. This is an in-line event that produces this error type when a favorable
response is received from running the Digital Line Electronic Power Feed
Test (#11). No craft action is necessary. This alarm will be resolved with
the passing of time.
g. With Aux Data 40963, this error type is a result of an unfavorable response
to the Electronic Power Feed/ Positive Temperature Coefficient Test (#11).
With Aux Data 40988, this error type indicates that the EPF/PTC circuit has
been turned off due to an overcurrent condition.
For TN754 vintage 13 or earlier and TN413, the EPF circuit senses an
overcurrent condition at the voice terminal. Check for a short in the wiring,
a damaged jack, an incorrect type of voice terminal, or a defective voice
terminal.
For TN754 vintage 14 or later, TN754B and TN2136, the PTC will open if
there is a short on the power line for 1/2 second or longer. The voice
terminal is probably not operating properly. Unplug the voice terminal for
30 seconds and then plug it back in. If the voice terminal still does not
operate, then check for a short in the wiring, a damaged jack, an incorrect
type of voice terminal, or a defective voice terminal.
Once the problem has been resolved, it may take up to 1 hour for the
alarm to clear due to ‘‘leaky bucket’’ strategy. If the problem cannot be
resolved by one of the steps above, then replace the circuit pack.
