							Comdial®strives to design the features in our communications systems to be
fully interactive with one another. However, this is not always possible, as the
combinations of accessories and features are too varied and extensive to insure
total feature compatibility.
Accordingly, some features identified in this publication will not operate if
some other feature is activated.Comdial disclaims all liability relating to
feature non-compatibility or associated in any way with problems which may
be encountered by incompatible features. Notwithstanding anything contained
in this publication to the contrary, Comdial makes no representation herein as
to the compatibility of features.

Describing The 12A Features
Automatic Redial Feature
This feature enhances automatic redial by adding a multiple redial feature.
When installers enable this option, the station can have multiple numbers queued for ARD (automatic
redial). You can enable this feature for as many as 240 stations at a time in DXPPlussystems.
When you enable multiple ARD, a station can store up to the last 10 numbers its user dials as the user
dials the numbers. As the user dials the 11th number, the system drops the oldest number and adds that
last dialed number at the top of the list of the 10 stored numbers. It repeats this sequence as the user
makes more calls during the day. The system will compare a selected line along with a newly dialed
number with its currently stored list. If it encounters a match, it does not store the number again; however,
it does move the matched line/number to the top of the list.
After the station user starts a redial on some of the numbers in the stored list, only the places in the list
occupied by numbers not currently being redialed remain available for new number addition.
When the user starts the ARD feature, the telephone will redial the stored number. With multiple ARD,
the telephone will redial all stored numbers one at a time, in the order that they are stored in the queue,
until (a) the call is answered, (b) the user cancels the automatic redial feature for a particular number, or
(c) the telephone has dialed the number a preprogrammed number of times.
If the system encounters a busy or unavailable line (for lines that have provision for reporting such
matters) or if the system encounters a ring-no answer, and it has not dialed the number the
preprogrammed amount of times, it moves the number to the bottom of the queue and tries the next
queued number just as soon as the redial delay times out.
To completely program the automatic redial feature, the installer must enable the multiple automatic
redial feature and adjust the following feature parameters:

							Suspend ARD
With this Suspend ARD feature selected, user activity at a station suspends automatic redial action until
the user completes the activity. When the user activity ends, the system automatically resumes the
automatic redial action. Also, users can dial a code to manually suspend ARD action until they choose to
restart it by either pressing the ARD button or by dialing the code once more. With the feature disabled,
any user activity cancels further ARD action.
ARD Answer Supervision
With the ARD Answer Supervision feature selected, and the line that the system is using to make the call
provides answer supervision capability, the system stops the ARD activity when the called party answers.
Wait For Answer
The ARD Wait For Answer feature sets the maximum time the system will wait for an answer signal or
user activity before it cancels the ARD action after it redials the number. If neither call answer nor user
activity occurs, the system terminates the call and retries the call unless the maximum number of retries
has been reached.
If the line provides busy detection, the system disconnects the call and provides a five second busy tone to
the calling station. In this situation, the calling station remains in the redial mode until the busy tone
stops. Any user activity during this period deactivates ARD for the number.
ARD Retry Delay
The ARD Retry Delay feature sets the time the system waits before redialing a number or between
redialing one number and the next when multiple ARDs are active. If ARD activity is suspended at the
time the retry delay timer expires, the number to be redialed next remains at the top of the queue to be
redialed first when ARD resumes.
ARD Retries
The ARD Retries feature sets the maximum times the system will automatically redial a queued number.

							Data Interface Unit Support
The Data Interface unit (DIU) provides the capability for using Industry Standard Telephone (IST)
devices on a digital station port. These devices include such items as: an Industry Standard Telephone, a
FAX machine, modem, a cordless telephone, or an answering machine.
The DIU connects to a digital station port and provides connections for both a proprietary multiline
digital telephone and an IST device. The user can switch between the telephone and the IST device by
pressing a DATA button on the telephone. The DATA button’s status light indicates the operating status
on the DIU.
Installers can arrange for remote control of the DIU from station ports other that the local station port (for
example: those stations in the DIU’s security group) by assigning a DATA button to those stations as
well; however, the system blocks their remote command when the local station port is busy with a call.
Installers assign control capability to a system station (either the local station port or a remote port), by
mapping a DATA button on the station.
NOTE: The DIU is not compatible with Impact telephones to which installers have connected an
IST module inside the adjustable pedestal.
Installing The DIU
The DIU is a self-contained unit that includes the DIU cabinet, a wall transformer power supply with
attached power cable, and a telephone line cord for system connection.

							Installing The Mechanical Components For The DSU
Install the DIU in either a free-standing manner or mount it on a wall.
When mounting the DIU on a wall:
1. Select a location that is close to a standard 115 VAC electrical wall outlet. The location you select
should also be convenient to the digital telephone and the Industry Standard Telephone (IST), FAX,
or modem—whichever one you will be connecting to the DIU.
2. Mark two locations for the mounting screws as follows:
a. make the first mark,
b. measure 3 13/16 inches horizontally from the first mark and make the second mark.
3. Install two #8 x 3/4-inch screws in the wall at the marked locations. Tighten the screws until the
screw heads are 1/4-inch from the surface of the wall.
4. Place the DIU on the wall with the screw heads inserted into the slots provided on the bottom surface
of the DIU. Slide the DIU onto the screw heads until it is firmly attached to the screws.

							Making The Cable Connections For The DIU
Four cable connections are required to the DIU—station line cord, digital telephone line cord,
IST/FAX/MODEM line cord, and power cable.
1. Disconnect the line cord on the digital telephone from the digital station port connector and plug it
into the connector labeled PHONE on the DIU.
2. Plug the line cord from the IST device (such as a FAX machine, or modem) into the DIU connector
labeled FAX/MODEM.
3. Plug the power supply transformer into a 115 VAC electrical wall outlet. Connect the other end of the
power cable into the DIU connector labeled POWER. The green LED on the DIU will be on to
indicate power is being supplied to the DIU.
4. Plug one end of a standard line cord into the connector labeled LINE on the DIU. Plug the other end
of the line cord into the digital station port connector.
NOTE:DIU power loss will create the same symptoms as the disconnection of the DIU from the
system. If this occurs, plug the multiline digital telephone directly into a digital station
port connector.
Arranging DIU Security Groups
Installers can program up to eight security groups and assign them to a particular class of service. Stations
that are in the same security group as a Data Interface Unit (DIU) station have access to that DIU station.
Stations that are in different security groups do not.
