GENERALDESCRIPTION
200.1 SYSTEM TEcHN0LoGY
The In&f& 4096 Hybrid Key Telephone System
is an expandable modular system engineered
for growth through modular card IPCB) expan-
sion as well as KSU module expansion and
provides a flexible assortment of features
through software options and optional circuit
cards. F&p-e 200-l is a block diagram of the
System.
The Zn$nf& 4096 Hybrid Key Telephone System
is the upper end of a family of Electronic Key
Telephone Systems designed to meet the needs
of telephone users from small to large. The
other members of this family are the In&f&
816 and 1224.
The In&&e 4096 Hybrid Key Telephone System
is a modular system designed for growth using
state of the art Di&al Technology for switching
control. command processing and also utilizes
a CMOS based microprocessor controlled cross
point switching matrix, and provides a fl&ble
assorunent of features.
This family of systems Is englneered ‘to allow
the same telephones to migrate through the
complete product line.
This system has a capacity of up to 40 outside
lines. 96 internal telephone stations. and 14
intercom channels. The system architecture
allows for non-blocking access to all 40 CO
lines. The KSU is designed as two cabinets.
The Basic cabinet will support 24 outside lines
and 48 internal stattons. The Expansion cabi-
net will support an additional 16 outside lines
and 48 internal statlons. Standard single-line
(2500 type) telephones can be installed in the
system by exchanging key telephone boards for
single-Une boards.
200.2 COMMON EQUIPMENT

Basic Key Sewice Unit (BKSIJj
The Basic KSU is housed in a wall-mount
cabinet that contains card slots for modu-
lar boards and associated pre-wired con-
nectors. The KSU provides card slot
positions for DC/DC Converter (DC/DC),
Central Processing Board (CPB), 24
CO/PBX lines (3 COB’s), 48 stations (6
KIB’sl. an Application Board (APL), and
two Power Failure Transfer untts. One (1)
BKSU is required per system.
Expansion Key Service Unit [EKSUJ
The Expansion KSU is an add-on cabinet
that mounts next to the Basic KSU with
ribbon cable connectors to interface to the
Basic KSU, card slots to support up to 8
PCB’s and a pre-wired CO line interface
connector (a). The lQcpa.nsion KSU will
support a configuration of 16 CO lines and
48 Key Telephones/DSS Units/Phone
Boxes. One (1) EKSU is required when the
system exceeds 24 CO lines or 48 stations.
Two power supplies are required in the
External Power Supply Housing (EPS) for
Expansion KSU operation.
External Power Supply Housing (EPS)
The External Power Supply Housfng (EPS)
is a wall mountable cabinet that houses
the EPS motherboard (backplane), two
Power Supply Units 0%). the Single Lfne
Ringing Generator and Message Waiting
Power Supply Unit (RG), and the Battery
Charging Unit (BC). The EPS contains an
ON/OFF power switch. an AC input cord.
a DC output cord, battery connector panel
for connecting 24V dc of battery power, an
AC ON LED, a DC ON LED and a RING ON
LED for the Battery Charging Board (BC).
One (1) EPS Is required per system.
