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.

IMI66–132 DSU II Digital Telephone System

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.

1.4 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.
