Comdial strives to design the features in our communications systems to
be fully interactive with one another. However, this is no t 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.

IMI66–107 Digital Telephone System
1.3 Accessory Information
The digital telephone system is capable of supporting several accessory software and hardware
devices. You can add voice mail, industry standard telephones, and headset capabilities to your
digital telephone system.
1.3.1 The Analog Terminal Interface
By employing the Analog Terminal Interface device (ATI-D), the digital telephone system can
support the operation of the following accessories:
ExecuMail and Versatile Voice Processing,
•
Industry-standard telephones and telephone devices.
•
For more information on the ATI-D, see section 2.19.2, Installing The Analog Terminal
Interface.
1.3.2 Headset Operation
The Comdial DigiTech speakerphones with product codes of 7700S, revision H and earlier,
include a built-in headset port. Speakerphones with a revision of I and later and Impact LCD
speakerphones with product code 8024S provide an auxiliary jack for headset interface.
Contact your Comdial Inside Sales Representative for a list of compatible headset
manufacturers.
NOTE: The system delivers subdued off-hook voice announce (SOHVA) messages to the headset
port. Because a telephone headset exhibits a coupling effect between the ear piece and
the microphone, it may allow the outside party to hear the SOHVA message.
Introducing The DSU 1 – 5
Digital Telephone System IMI66–107
1.3.3 Battery Back Up
You can install an optional battery backup that provides power to the system in the event of a
power failure. For more information, see section 2.20.1, Installing The Battery Backup.
1.3.4 DSS/BLF Console
You can add a separate DSS/BLF console to provide additional DSS/BLF buttons to a particular
station (such as an attendant). These additional DSS/BLF buttons work just like the DSS/BLF
buttons on the telephone. For more information, see section 2.6, Installing The DSS/BLF
Console.
1.3.5 Caller ID
Using the Caller Identification Interface (product code CID08), the digital telephone system
provides caller ID information as part of the SMDR printout and as ASCII data input for use
with personal-computer-based application programs.
1.3.6 Tracker
With Tracker you can send messages to Tracker Pagers assigned to a station extension number.
When the pager is activated the user reads the message on the pagers LCD display. The system
delivers alpha/numeric or numeric-only messages depending on the Tracker Model being used.
1.3.7 DVA
Digital voice announcing uses a hardware peripheral device (product code DVA01) connected to
a digital station port to play recorded messages during an in-progress call. The DVA stores the
messages in its memory for recall when needed.
1.3.8 DIU
The Data Interface Unit (DIU) is a device connected to a digital station port of a DSU. The DIU
provides connections for a digital multiline telephone and another device such as a industry
standard telephone (IST), FAX, or modem. The DIU swithces the voice path from the DSU to
either the digital telephone or the IST by pressing a button on the digital telephone.
1 – 6 Introducing The DSU
IMI66–107 Digital Telephone System
1.4 Hardware Summary
The digital telephone system consists of an electronic Digital Service Unit (DSU)usually referred
to as common equipmentoptional expansion modules to extend station and line capacities,
dedicated digital electronic key telephones, and interconnecting wiring consisting of small, 2- or
4-conductor, twisted-pair cable. The digital telephone system supports all Comdial proprietary
digital telephone models.
NOTE: Sxxxx software only supports DigiTech telephones; Ixxxx software supports all digital
telephones.
The station and line capacity of the base unit and optional expansion module are detailed in the
following chart.

1.5 Common Equipment Description
The common equipment base unit is a fully electronic device. It is essentially a special purpose
computer system acting as a communications controller between central office (CO), private
branch exchange (PBX), or CENTREX supplied lines and the proprietary digital telephone
stations. The software design of the common equipment provides complete system support and
great flexibility of operation.
The system is fully digital with two usable time slots available for each station. Digital
information is computer-encoded voice transmission and control signals. After a computer
translates analog voice transmissions to digital information, the digital signals travel through
time division multiplexing (TDM) highways. The TDM highway can transmit several signals
over a single pair of wires at the same time. A system clock partitions TDM information into
time slots. A time slot is a portion of time assigned to a particular position of the system clock.
Each time a particular clock position is reached, the computer reads information associated with
that position. As the system clock goes through its cycle, the computer passes digital information
between pieces of equipment sharing time slots.
The common equipment consists of a base unit, which provides complete feature support, and
optional expansion modules for additional lines and stations. It is contained in a contemporary
metal housing designed to be inconspicuous in a modern office environment. It is engineered to
be wall or rack mounted.

The digital telephones used with the digital telephone system are electronic,
microprocessor-controlled, devices. They allow not only multiline pickup but also single button
access to features available from the serving CO, PBX, CENTREX, or common equipment. The
digital telephones are available in several different styles with several models available in each
style. The following list details the available telephones.
