Notes:
a. Error Type 1 with Aux Data of 40987—This Error Type with Aux Data
40987 could indicate 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.
Error Type 1 with Aux Data of 1 to 20—This Error Type and Aux Data 1
to 20 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.
b. Error Type 18—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 UUCSSpp | PCSSpp command.
c. Error Type 130—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.
d. Error Type 257—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.
e. Error Type 767—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.
f. Error Type 769—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.
