e. This indicates that the EPF has been turned off due to an overcurrent
condition at the voice terminal. Check for defective wiring or a damaged
jack, and make sure the voice terminal is a Hybrid set. Once the problem
has been resolved, the alarm is retired after a predetermined period of
time.
f. This indicates that the voice terminal has probably been disconnected or
that there is a problem in the wiring to the terminal. Make sure that the
voice terminal is connected or check for defective wiring to the voice
terminal.
g. Note that Error Types 769 and 1281 by themselves create Warning alarms
only, but if both are present, a Minor alarm is logged.
h. This indicates that there is something wrong with the data link to the voice
terminal. An in-line maintenance error has generated an off-board
warning. Ignore it if there are no complaints. Otherwise, make sure the
voice terminal is connected, check for defective wiring, check for a
defective voice terminal, and 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.
i. This indicates that the station went off-hook while in the disconnect state.
Use the
status station
command to determine the state of the station. The
off-hook should have moved the station to in-service. No system
technician action is necessary.
j. This is the code that is generated when the link between the circuit pack
and the voice terminal is successfully reset. No system technician action
is necessary.
