Notes:
a. Could experience a noisy port or link. This is an off-board p roblem
detected by the port circuit. Chec k for defective wiring , a defective voice
terminal, or move voice terminal c loser to the switch (in terms of feet of
wire from the jack to the switch). If the p roblem still exists, replace the
circuit pack. Onc e 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 d etected with the link to the terminal. When an error
with the link is detected, an on-board counter is inc remented.
The user could experienc e a noisy port or link. This is an off-board
problem detected by the port c ircuit. Check for defec tive wiring, a
defective voice ter minal, or move voice terminal c loser to the switch (in
terms of feet of wire from the jack to the switch). If t he problem still exists,
replace the circuit p ack. Once the p roblem has been resolved, the alarm
will be retired after a prede termined amount of time.
c. This error type is logged when the port in question is b usied out by
maintenance personnel. Make sure p ort is released from busyout via the
release port PCSSpp command.
d. This error type indicates that t he 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 p roblem can be c aused
by defective wiring. Defective wiring can cause varying degrees of
problems on different types o f sets. Sets such as the 7410 appear to b e
more susceptible to wiring problems than other sets. This is usually an
on-board problem and can be ig nored if no user complain ts are received.
f. This is an in-line event that produces this er ror 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 unfavorab le 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 ove rcurrent condition.
For TN754 vintage 13 or earlier, the EPF circuit senses an overcurrent
condition at the voice terminal. Check for a short in the wiring , a damaged
jack, an incorrect typ e of voice terminal, or a de fective 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 seco nd or longer. The voice
terminal is probably not operating prop erly. Unplug the voice terminal for
30 seconds and then p lug it back in . If the voice terminal still does no t
operate, then check for a short in the wiring, a damaged jack, an incorrect
type of voice terminal, or a d efective voice termi nal.
