c. This error type is logged when the p ort in question is busied ou t by
maintenance personnel. Make sure p ort is released from busyout via the
release port UUCSS pp/PCSSpp command.
d. This error type indicates that the c ircuit pack has been remove d 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 prob lem can be caused
by defective wiring. Defective wiring can cause varying deg rees of
problems on different type s of 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 ignored if no user complaints are received .
f. This is an in-line event that produces this error type w hen 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 respons e
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 and TN413, the EPF circuit senses an
overcurrent condition at the v oice terminal. Check for a short in the wiring,
a damaged jac k, an incorrect type of voic e terminal, or a defective voic e
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 properly. Unplug the voice terminal for
30 seconds and then p lug it back in. If the voi ce terminal still does not
operate, then check for a shor t in the wiring, a damaged jack, an incorrect
type of voice terminal, or a d efective voice terminal.
Once the problem has b een resolved, it may take up to 1 hour for the
alarm to clear due to ‘‘leaky b ucket’’ strategy. If the problem cannot b e
resolved by one of the steps ab ove, then replace the circ uit pack.
h. An in-line maintenance error has generated an off-board warning d ue to
some problem with the link to the voice terminal. This c an be ignored if no
user complaints are received . Otherwise, make sure the voice terminal is
connected, c heck for defective wiring , check for a defec tive voice
terminal, and move voice termina l to a jack that is closer to the switc h (in
terms of feet of wiring between the jac k and the switch). If the prob lem still
exists, replace the circ uit pack. Once the prob lem has been resolved, the
alarm will be retired after a pred etermined amount of time.
i. This indicates that the station went off-hook while it was in the
ready-for-service state. Use the status station c ommand to determine the
state of the station. The off-hook should have moved the station t o
ready-for-service. No craft ac tion is necessary.
