    							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.

    							1.6 Station Descriptions
    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.
