Should the intercom line be selected with no subsequent action
taking
place,
the system will timeout the active status and return the
station to an idle state.
Bach station is equipped with a last number redial feature.
This
feature will save the last number manually dialed from the keypad. It
will redial the saved number upon key command.
A newly dialed number
will automatically replace a currently saved number.
If a station is programmed to include a prime line, this line will be
automatically selected for a manual dialing operation when the handset
is taken off hook.
If the prime line is busy,
a manual line selection
must be made.
Auto dial and speed dial numbers can be programmed to include any
particular line desired.
When this is done,
an auto dial or speed
dial operation automatically selects that line for dialing.
Should
that line be busy,
manual line selection must be made.
(If a line is
selected manually for a speed dial call,
either station or system,
press the HOLD key before pressing the speed dial key on the key pad.1
If a particular line is not programmed for selection as part of the
auto or speed dial,
the prime line (if programmed) will be

automatically chosen.
If the prime line is unavailable or busy, the
last line used to originate a call will be chosen.
Other than the prime line or the auto/speed dial line selection,
automatic preselection of a line is not part of the system.
A line
can be manually selected before lifting the handset (for handsfree
dialing) or after the handset is lifted.
The key pad is automatically
set for manual dialing when a manual line selection is made.
A key activated feature at each station will place a PBX or TELCO line
on hold and provide music-on-hold to the held party if that capability
is available.
Pressing the HOLD key once effects a normal timed hold condition.
Any
station which has access to the line can pick up the held call.
The
normal hold condition will hold a call for a programmed length of
time.
At the end of the first timeout period, the line select
indicator will flutter rapidly at all stations and three quick tone
bursts will sound at the holding station.
At the end of each
subsequent timeout period,
the holding station receives an additional
three quick tone bursts.
