SYSTEM OVERVIEW
System Overview
SECTION 1
INTRODUCTION
The digital telephone system is an expandable
communications system with many attractive
characteristics including the following:
Unitized base unit which includes all system
features. 
The base unit is full featured and
self-contained.
Expansion modules which increase station and
line capacity. 
A 4-line, 8-station expansion module is
available. It can be added singly or in pairs to
increase the station and line capacity of an existing
base unit installation.
Secure off-hook voice announce (SOHVA) feature.
The SOHVA feature allows a station user to talk to a
busy station without being heard by the outside party
at the busy station. The called user can easily send
back a pre-programmed LCD message or talk to the
caller without being heard by the outside party.
Programmable buttons. Many of the telephone
buttons can be programmed to provide functions such
as direct station selection (DSS), auto dial, systemfeature access, line access, messaging and more.
Programmed buttons helps station users eliminate
manual dialing errors.
Service 
observing. Supervisors can help insure
quality of service without interrupting calls by
monitoring a trainee’s call without being heard by the
distant party at the trainee’s station.
Handset volume control on all stations. Handset
volume can be set to a comfortable listening level for
each individual user of the telephone.
Call cost display. Built-in software records all
outside call costs. Special programming allows an
LCD speakerphone to display the accumulating cost of
a call.
Dual intercom. A second intercom key can be
provided so that station users can handle two intercom
calls at once. One intercom call can be placed on
hold while a second intercom call is serviced or both
calls can be 
conferenced together.

HARDWARE SUMMARY
System Overview
The digital telephone system consists of an electronic
Key Service Unit (KSU) base unit, usually referred to
as common equipment, optional expansion modules to
extend station and line capacities as required, a
software cardridge containing the operating 
System
programming, dedicated digital electronic key
telephones, and interconnecting wiring consisting of
small, 
2-- or 4--conductor, twisted-pair cable.
The station and line capacity of the base unit and
optional expansion module are per the following chart.

The digital telephone system is full featured, and
supports the digital telephone models.
The digital system is expandable in both line and
station 
capacity with the addition of add-on expansion
modules.Refer to 
Figure 3-14 on page 3-24 for an
illustration of the expansion configurations.COMMON EQUIPMENT 
DESCRlPTlON
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 off ice (CO), private branch exchange
(PBX), or 
CENTREX supplied lines and the proprietary
digital telephone stations. The software architecture
of the common equipment provides complete system
support 
and great flexibility of operation.
The system is fully digital and is 
ISDN up-gradable
with two usable time slots available for each station.
The digital information passes over time division
multiplexing (TDM) highways. The digital information
is an encoded version of the voice transmission and
control signals that are translated into computer
language. The TDM highway can transmit several
signals over a single pair of wires at the same time.
The signals are governed by a system clock. This
clock creates an overall point of reference against
which the TCM information is synchronized and
partitioned 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 information associated with that positioncan be read. As the system clock goes through the
clock cycle, all necessary digital information is passed
between the pieces of equipment sharing the highway.
The common equipment consists of a base unit, which
provides complete feature support, and optional
expansion modules which provide extended station
and line coverage.
The wmmon equipment is contained in a functional,
modem-style metal housing of contemporary design in
keeping with the needs of the modem off ice
environment. It is engineered to be wall or rack
mounted. The outline dimensions of the common
equipment base units are illustrated in 
Figure l-l.
STATION DESCRIPTION
The digital telephone stations employed with the
digital system are electronic, 
microprocessor-
controlled, devices. They allow not only multiline
pickup but also single key access to features available
from the serving CO, PBX, or 
CENTREX switch as
well as the wmmon equipment. The digital telephone
is available in two different images. The features of
the images are as listed below and as detailed in
Figure l-2 and in Figure l-3.
The wide-image digital telephone provides the
following features:
