Comdial’s Quality Management System Is
Certified To The ISO 9001 Standard.
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.

1.2 Understanding The DXP Plus
Station and line
capacity
The DXP Plus system is a 480-port, three-cabinet, digital communications system
consisting of one main cabinet and two expansion cabinets. With analog,
loop-start, DID, or multipurpose line boards, the maximum configuration is 0
lines and 480 stations, or 232 lines and 8 stations. By using the digital carrier
transmission option (E1 or T1), however, you can enhance the system’s capacity
to a maximum of 560 ports, with a 240 line and 320 station maximum
configuration.
How the system
works
The Comdial DXP Plus digital communications system provides cost-effective
voice and data communications using the latest PCM-TDM (pulse code
modulated/time division multiplexing) digital switching technology. The DXP
Plus switching architecture provides a non-blocking switching array that gives all
ports simultaneous access through the system. The digital technology allows
simultaneous voice and data transmission using 2B+D signaling (CCITT
specification for basic access data transfer rate for ISDN on a single twisted pair)
when data terminals become available. The design is a fully modular, ISDN
(integrated services digital communications network) system with 1024 usable
time slots and the flexibility for upgrade and expansion as needed. The DXP Plus
digital communications system supports the current Comdial line of DigiTech,
Impact, and ExecuTech telephones.

Reviewing The Hardware
3.1 Understanding The Printed-Wire Boards
The basic system consists of a main cabinet, which accepts 14 printed-wire boards, and two expansion
cabinets; the upper expansion cabinet accepts twelve printed-wire boards, and the lower cabinet accepts
eleven (see Figure 7). Some of the printed-wire boards also hold smaller circuit cards that mount
directly to the boards (See section 3.5 for card information) The line boards are listed in section 3.3;
station boards are located in section 3.4. The complement of circuit boards include the following (for
information on the main DXP Plus package, see section 3.6, Locating The Boards):
Auxiliary Board:
A utility board that provides interface for a maximum of four special-purpose circuit cards.
Actual make-up requirements depend upon system configuration.
Central Processing Unit (CPU) Board:
Provides central processing and control for the system and other miscellaneous functions. The
CPU board has the time switch and conference circuitry and two serial data ports, which have
been dedicated for PC-based programming and a remote maintenance modem.
Conference Board:
Provide additional conference capability. Each board provides 5 additional 3-way conferences.
Interface Boards:
Ties the main cabinet to the expansion cabinet. Each expansion cabinet has an interface board;
that connects the main cabinet with the expansion cabinets. Interface boards are included with the
expansion cabinet packages.
Memory Card:
Provides the memory storage and operating system control. The card mounts directly onto the
CPU board, and it is available with two (four megabyte as a future feature) of memory. The
system uses re-programmable random access memory, known as “flash memory” or “flash
RAM” —not replaceable memory chips, known as “EPROM”.
Services Board:
Provides an interface for music-on-hold and background music inputs; it also provides an output
to an external paging amplifier. The services board includes four dry-contact relays for external
control functions. You can also add up to three additional cards onto the services board for data
communications, DTMF tone receiving, and E1 or T1 synchronization.

GCA40–130 DXP Plus General Description
12 – Reviewing The Hardware
3.2 Defining The Line Boards
The DXP Plus accepts several different types of lines. In order to use these various lines, you must
install the correct line board. The following list details all of the current DXP Plus line boards.
Direct Inward Dialing Line Board:
Direct Inward Lines (DID) are incoming only and are employed to reduce the number of channels
between the DXP Plus and the Central Office (CO). DID lines allow incoming CO calls to reach
internal intercom extensions without going through the attendant station. DID operation requires
a group of published directory numbers provided by the CO. The number of DID lines is limited
only by the number of installed DID boards. The DID translation tables have limits that may
affect DID capacities. The system supports a maximum of 400 DID lines.
Loop-Start Line Board:
The loop-start line board provides system interface for loop start lines. Loop start lines are the
most common CO line type (loop-start lines do not usually offer disconnect supervision)
Multi–Purpose Line Board:
The multipurpose line board provides system interface for ground start lines, loop start lines, and
E & M Tie lines; these are typically the three line types that the central office (CO) makes
available for connection. The multipurpose line board is programmable for each line type. You
can have a maximum of two Tie lines on each multipurpose line board.
E1 Line Board (available for international applications):
The E1 board provides 30 channels of voice transmissions over a single, four-wire, 120 ohm
cable or over two 75 ohm coaxial cables using multiplexing techniques. The system accepts a
maximum of eight E1 boards.
T1 Line Board (available for domestic U.S.A. applications)
The T1 board provides eight, 16, or 24 channels of voice transmissions over a single, four-wire,
cable using multiplexing techniques. The system accepts a maximum of ten E1 boards.
DXP Plus General Description GCA40–130
Reviewing The Hardware – 13
3.3 Defining The Station Boards
The DXP Plus accepts digital, analog, and industry standard telephones. In order to use these different
types of stations, you must install the correct station board. The following list explains each station
board.
Analog Station Board
The analog station board provides support for Comdial’s proprietary analog telephones (such as
the various ExecuTech models). Each board supports either 8 or 16 stations. A precharge port is
provided for board removal or insertion without system power-down.
Digital Station Board
The digital station board provides support for Comdial’s proprietary digital telephones (such as
the Impact and DigiTech). Each board supports either 8 or 16 stations. A precharge port is
provided for board removal or insertion without system power-down.
Industry Standard Telephone Board
The industry-standard station board provides support for industry-standard telephones. Each
board supports either 8 or 16 stations. A precharge port is provided for board removal or insertion
without system power-down.
GCA40–130 DXP Plus General Description
14 – Reviewing The Hardware
3.4 Defining The Option Circuit Cards
Many of the DXP Plus boards accept smaller circuit cards. These boards mount directly into the DXP
Plus, while the optional circuit cards mount only onto boards. You can install these optional cards on
any of the following boards: the Auxiliary Board, the Services board, and the Interface boards.
Synchronization Card
Adjusts the E1 or T1 transmit frequency to match the frequency from the CO. The
synchronization card mounts onto the Services board only.
Communications Card:
The optional communications card provides extra serial ports for the DXP Plus. The
communications card contains four serial communication ports and is attached to either the
Auxiliary board, the interface boards, or the Services board. You can install two communications
cards onto the lower two slots of any of these boards. The system supports a maximum of 18
serial data ports.
DTMF Tone Card
The DTMF Tone card expands the system’s industry-standard dialing capability. The system has
one IST DTMF receiver located on the services board while each DTMF card provides four
additional DTMF receivers.
