1.3 Detailing The 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 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, systems
•
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. The
Impression telephone provides headset capability through its handset jack.
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 II Digital Telephone System 1–5
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 2.18.1, 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 pager’s 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 switches 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 II Digital Telephone System
1.4 Summarizing The Hardware
The digital telephone system consists of an electronic Digital Service Unit (DSU)—usually
referred to as “common equipment”—optional 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.
The station and line capacity of the base unit and optional expansion modules are detailed in the
following chart.

1.5 Describing The Common Equipment
The common equipment base unit for the DSU II digital telephone system 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.
All DSU II systems have analog, loop-start line interfaces to the public switched network.
Special intergrated circuits (COder/DECoder or CODEC chips) in the line circuits translate
analog voice information to and from the digital domain. Internally, the system is fully digital
and has Pulse Code Modulation (PCM) highways that are time-division multiplexed into PCM
channels. Each digital station has two B-channels available for voice and/or data and one
D-channel available for telephone control. This arrangement is known as 2B+D. The system
maintains communication with the stations with digital loop transceiver circuits that are under
system software control. A time switch intergrated circuit, also under system software control,
routes calls, creates conferences, and set padding levels as required.
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.

1.6 Describing The Stations
The digital telephones used with the DSU II 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.
