GENERAL DESCRIPTION
200.1SYSTEM TECHNOLOGY
The infinite family of digital key telephone sys-tems is comprised of three fully digital 
hybridkey telephone systems, the DVX 
I, DVX ’ , and
DVX ‘II. These systems are designed to meet thetelecommunications needs of a small to me-
dium sized business offices. All digital systemsincorporate state of the art digital technology
for command processing and voice switching
utilizing a Pulse Code Modulation/Time Divi-
sion Multiplexing 
(PCM/TDM) voice control
module. The family of infinite Digital systems
are also engineered to allow migration of the
family of infinite digital terminals and terminal
accessories throughout the entire product line.In addition, standard 
2500~type telephone de-
vices are supported by use of a 2x4 SLT Expan-
sion Module on the infinite DVX 
’ system, a 4x8
ZLT Interface Board (CSB) on the infinite DVX
system, a Single Line Interface Board (SL12)on the infinite DVX 
I’ system, or SLA (OPX)
adapters on all three systems.
The DVX 
’ is the smallest member of the infiniteDigital family and fully configured supports a
maximum of 14 CO/PBX/Centrex lines and 28
digital station devices. The 
DVX’ is a “flat pack”,or single mother board system with plug on
modules expanding the system via expansion
and expander modules configured with either
two CO/PBX/Centrex lines by four stations or
four CO/PBX/Centrex lines by eight stations.
A complete system capacity allows for use of upto 112 time slots for stations,CO Lines, DTMF
Receivers, or data switching modules. This ex-tends non-blocking access to all system re-
sources.The DVX 
’ Basic KSU comes fully configured
with power supply, Common control processor,PCM/TDM Voice switching matrix and inter-
face circuits for four 
CO/PBX/Centrex lines
and interface circuits for eight Digital terminalstations. The Basic system is also equipped
with one RS-232C I/O port, one DTMF receiver,a connector for one Music-On-Hold channel
that also provides for background music, and
an on-board 300 baud modem that provides
access to the system for data base program-
ming or remote maintenance and or diagnos-
tics. Modules to provide additional I/O ports,
and an optional 1200 baud modem module can
also be added to the system.The DVX 
I1 system is the middle system in a
family of Digital Hybrid Key Telephone systemsand supports a maximum configuration of 28
CO/PBX/Centrex lines and 56 digital station
devices. The DVX I1 is a typical KSU system with
plug in PCB’s. The system capacity is expandedby installing four circuit CO/PBX/Centrex
lines by eight circuit station expansion PCB’s.
The complete system capacity allows for use ofup to 112 time slots for stations, CO Lines,
DTMF Receivers, or data switching Modules.
This extends virtual non;blocking access to all
system resources.A Basic DVX 
I1KSU ships complete with an
on-board power supply. The CPB which is the
only common equipment required for operationprovides the microprocessor for command
processing and Voice PCM/TDM switching. TheCPB is also equipped with one modular 
RS-232C I/O port, a connector for one Music On
Hold channel that also provides for backgroundmusic, and an on-board 300 baud modem that
provides access to the system for data base
programming or remote maintenance and or
diagnostics. Modules to provide additional I/O
ports, and an optional 1200 baud modem mod-
ule can also be added to the CPB.
The DVX 
‘I1 represents the larger end of the
family of Digital Key Telephone systems. This
system is designed to meet the telecommunica-
tions needs of a medium to large sized business
offices. The system incorporates state of the artDigital Technology for command processing
and voice switching utilizina PCM/TDM voicecontrol module. The DVXIIF
supports the sameinstruments as the DVX 
’ and DVX ‘. In addi-
tion, standard 2500-type telephone devices are
supported by use of a Single Line Board (SL12)and or SLA 
(OPX) adapters.
The DVX 
I’ is a member of the infinite family
and fully configured supports a maximum of 48CO/PBX/Centrex lines and 96 digital station
devices. The DVX” is card slot cabinet orientedwith plug in modules (cards) expanding the
system via station boards and CO boards. The
boards are configured as 12 CO/PBX/Centrex
lines, 12 digital stations, or 12 single line sta-
tions. A complete system capacity allows for useof up to 144 ports for Stations, CO Lines, or
Data switching Modules. This extends 
non-blocking access to all system resources. In its

initial release the system is configured in a pre
mapped arrangement, where peripheral boardsare plugged into designated slots. The hard-
ware architecture is built so that future expan-sion in both CO lines and Stations can be
accomplished by upgrading software and add-
ing plug in boards.
The system KSU is powered by modular power
supplies that are mounted on the sides of the
cabinet. The cabinet is divided so that one
power supply will support a system configured
with up to 48 CO lines and 60 stations (key or
SLT). If the CO line or station requirements
exceed the aforementioned configuration, the
second power supply is needed. The second
power supply will support the 
48/96 configu-
ration as well as possible future expansion re-
quirements.
The systems are installed using industry stand-
ard blocks, jacks and skinny wire cabling. Thiscombined with the ability to program the sys-
tem using a key terminal (digital display termi-
nal) reduces installation cost and maintenance
requirements.
All CO interfaces are equipped with transformerbarriers, for system classification as an FCC
fully protected system. Each CO circuit sup-
ports rotary (out-pulse) dialing and loop super-
vision (disconnect detection) under software
control. The DTMF tone signals and system
supervisory tones can be generated in each
keyset or on the main PCB. All infinite Digital
systems use a proprietary tone plan for provid-
ing internal progress tones with the exception
of OPX stations which are provided with a “pre-
cise” tone plan.The 
infiite family of digital terminals include
an Executive (display), Enhanced (non-display)Digital Terminals, and a Basic (non-display)
Digital Terminal. Optional station terminals in-
elude a Digital DSS Console, and a Single LineAdapter (Off-Premise Extension 
(OPX) adapter)
which are all upward and downward compat-
ible to the entire infinite digital product line.The system architecture allows system pro-
gramming changes to be made without inter-
rupting state event software control of normal
communications. Call processing continues
while the customer database is updated. All
progrsmming changes to the customer data
base programming are made either from a digi-tal display terminal connected to Port 01 or
from a data terminal or PC connected to eithera I/O port or remotely via the on-board 1200
baud modem (future).The 
infiite product line is tailored to meet
immediate and long term customer needs. Most
commonly used features are activated by directbutton selection. However, many functions
may be alternately accessed by dialing specificcodes or as another option by assigning these
dial codes to a FLEX button on a digital termi-
nal. This permits flexible use of the infinite
Digital systems.Future software enhancements and upgrades
are easily retrofitted and installed in the sys-
tem. This will in most cases provide backward
compatibility with existing 
infinite Digital hard-ware further reducing the cost to upgrade or
add features to an installed system.

the KSU. One terminal position can be
used to connect the ground wire from a
ground source.
Power Supply
The system KSU is powered by modular
power supplies that are mounted on the
sides of the cabinet. The cabinet is dividedso that one power supply will support a
system configured with up to 48 CO lines
and 60 stations (key or SLT). If the CO line
or station requirements exceed the afore-mentioned configuration, the second
power supply is needed. The power sup-
plies provide the system with 24V power.
They are plugged into a 120V ac circuit.
The power supply and cabinet meet all
safety requirements to comply with UL
1459 Second Edition and CSA C22.2 No.
225 standards.
B.Central Processor Unit (CPU)This plug-in card is one of two common
equipment cards required to make the sys-
tem operational. The CPU card controls allsystem activity. The CPU contains the
main micro-processor a 16-bit (68302), the
slave microprocessor (another 
68302), and
a real time clock. The master and slave CPU
chips are connected via a serial communi-
cations link. The CPU is responsible for all
control functions, execution of all logic op-erations, and control of system modules.
The master CPU also provides software andhardware support to ensure the following:
l Watch dog timer and recovery.
l State/Event software design.
l Battery Backup of Customer Database
RAM memory.The slave CPU ensures the following signal
processing functions are done:l PCB status as to presence/absence of
cards for automatic software configura-
tion setup.l Interpret an ID code from each PCB so
that card type can be determined auto-
matically.l Process interrupts from peripheral
cards and scan VCB.
In addition there is one RS-232 (modular
connector) input/output port on the CPU
and a connector to support the use of an
optional Backplane I/O expansion mod-
ule. The Backplane I/O Expansion Moduleadds two RS-232C I/O ports to the system
for a system total of three I/O ports. A reset
(halt) push button switch is located on thefront of the PCB.
System software is provided in EPROM
memory and is installed on the CPU. The
CPU contains 5 12 kilobytes (expandable to4MB) of EPROM memory storage and is
equipped with 256K of battery-backed
static RAM (expandable to 2MB). Provi-
sions have been made on the card to ad-
dress up to four megabytes of EPROM
memory and up to two megabytes of static
RAM.l
A Battery jumper strap is located on theCPU board. Jumpering from pins 1 
& 2
disables the Battery Backup. Between
pins 2 
& 3 enables the Battery Backup
option.l
The CPU allows the use of either 1 Mega-bit or 4 megabit static RAM chips to be
used for RAM memory.
LEDs 8~ Indicators
Three green 
LEDs located along the front
edge of the CPU provide an indication of thepresence 
of-12Vdc, +12Vdc & -5Vdc. Two
red 
LEDs provide the system heartbeat
indication.I/O Ports 
- Wiring/Pinouts/ConnectionsThe Central Processor Unit contains one
RS-232C, 8-pin modular jack type comrec-
tor, I/O Port (future) located near the front
edge of the PCB. This I/O port is capable oftransmitting and receiving data at 300,
1200, 2400, 4800, and 9600 baud rates.
In the future, this I/O port can be used forSMDR output, Remote programming thru
a data terminal or PC, ICLID output, or
interfacing with the infinite 
PC/ACD Re-
porting package.200-4
