Description Of System Features
IMI 66-097
Automatic Privacy
(Programmable)
A line can be made private or non-private through
class of service programming. In the private mode, a
station has exclusive use of the line during a call. No
other station can access that line unless it is included
through the use of the add-on conference feature. In
the non-private mode, all stations with that line ap-
pearance can gain access at the same time (some-
times known as common line pickup). A line Is
specified as private or non-private through system or
administration programming. Also see the discussion
titled Add-on Conference And Privacy Release.
Automatic Redial (Of Busy
Number Or Unanswered Call)
Automatic redial of the last dialed number can be
made available at every station through button
programming. In most cases, the station user must
program a button for use as an auto redial button; how-
ever, some telephone models provide an Al 6 button
as part of the A-button field and this provides an auto
redial function as a fixed feature. With this feature, a
busy number or an unanswered call can be redialed
repeatedly. Once automatic redial is activated, the sta-
tion will select the line, automatically dial the number,
and watt for a response. tt will do this once a minute
for approximately 10 minutes. The user must lii the
handset to take immediate control if the call is com-
pleted. Users of the optional speakerphone station
can take control by pressing the SPKR button instead
of lifting the handset.
Auxiliary Equipment Interface
A non-key system telephone device or data device can
be connected ahead of the common equipment on cer-
tain line ports across the tip and ring leads. Special
terminals in the line jack are provided for this purpose.
The system can detect an off -hook condition in the
connected device, and turn on the line status light at
the key system telephone stations with access to the
line to indicate the busy condttin.

Station Ringer
nterface
The auxiliary station ringer interface provides ‘dry-con-
tact” relay closures whenever station 19 rings. The
contact closures track the ringing pattern of station 17,
and can be used to control an external sign.alling
device. When a particular station port is programmed
to function as a PA port, the auxiliary ringer interface
relay contacts automatically become supervisory con-
tacts, They close when the PA port is called In this
configuration, they are used to enable an external PA
system. Also refer to the discussion titled Common
Audible Ringer Interface.
Background Music
If an external music source is provided, background
music can be turned on and off at individual stations.
Background music automatically turns off during calls.

The system provides all of the basic, lA24ype, key
service features. These features are: selective line
pickup, common line pickup, multiline pickup, and hold.
Battery Back-Up
(Chassis, Cable, And Batteries)
Battery back-up assemblies including chassis, cable,
and battery are offered as optional kiis (available from
Comdial). The assemblies are designed to connect
directly to the un-lntertuptable power source (UPS) in-
terface located on the common equipment chassis.
No user intervention is required with this feature, and
no class of se&e programming is required.
Battery Back-Up interface
Provision has been made for attaching a Corndial
provided optional battery back-up kit to give full
unintenuptable system power in case of an AC power
bss. The switching and trickle charge circuitry are in
the common equipment, while batteries, chassis, and
cable are packaged as a separate option. When
plugged into an active AC power source the common .
equipment will constantly charge the attached bat-
t&es with a trickle current. Built-in circuitry automat-
ically switches to battery power when AC power is lost.
With batteries at full charge, a fully loaded system will
operate for a minimum of one hour without AC power.
No class of service programming is required.
Call Announce With Handsfree
Answerback
The internat speaker at each muttiline station provides
call-announce capability over the intercom link. A
handsfree response to a call-announce call can be
made. This response is transmitted by the microphone
built into the handset. Also refer to the discussion
titled Voice AtVWutE8 Blocking
Call Pickup - Directed
A user at any station can dial a special prefix code, fol-
lowed by the number of a ringing station, to answer a
ringing call at that station.
