e. Error Type 130 indicates that the circuit pack or media module has been removed or has
been insane for more than 21 minutes. To clear the error, reinsert or replace the circuit pack
or media module.
f. Error Type 257 indicates problems transmitting to the voice terminal. This can be caused
by defective wiring, which 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.
g. Error Type 767 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 is resolved with the passing of time.
h. Error Type 769 with Aux Data 40963 is a result of an unfavorable response to the
Electronic Power Feed/ Positive Temperature Coefficient test (#11).
i. Error Type 769 with Aux Data 40988 indicates that the EPF/PTC circuit has been turned off
due to an overcurrent condition.
S8700 | 8710 / S8500
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. If the
problem cannot be resolved by one of the previous steps, then replace the circuit pack or
media module.
j. Error Type 1026: There is a problem with the voice terminal EEPROM. When the voice
terminal is repaired the alarm will be resolved with the passing of time.
k. Error Type 1537: An in-line maintenance error has generated an off-board warning due to
some problem with the link to the voice terminal. This can be ignored if no user complaints
are received. Otherwise, make sure the voice terminal is connected, check for defective
wiring, check for a defective voice terminal, and move voice terminal to a jack that is closer
to the switch (in terms of feet of wiring between the jack and the switch). If the problem still
exists, replace the circuit pack or media module. Once the problem has been resolved, the
alarm will be retired after a predetermined amount of time.
l. Error Type 2304: Internal system error. No action is necessary.
