mounted on a 4’ x 6’ x 3/4” plywood. A fullyloaded cabinet can weigh approximately
130 lbs. Make certain proper mounting
procedures are followed.
Check local building and electrical codes
before mounting the system. For example,
certain areas may require a flame
retardant plywood back board.
1. Mount the cabinet to the plywood using
3/4” #12 pan-head sheet metal screws
such that the top of the cabinet is approxi-
mately three feet 
( 1 meter) from the ceiling,
and bottom is at least six feet (1.8 meters)
from the floor. Make certain before mount-ing the cabinet that circuit cards slide
easily in and out of their respective card
slots.
2.Use the mounting template supplied with
the cabinet to locate the mounting holes.Also refer to Figure 500-3 Basic KSU
Cabinet Mounting Dimensions.

3.Drill the holes and mount the cabinet.
C.Central Processor Unit (CPV)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.
wRefer to Figure 200-2 Central ProcessingUnit (CPU). The master CPU also providessoftware and hardware 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-232C (modularconnector) 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 the
front of the PCB.System software is provided in EPROM
memory and is installed on the CPU. The
CPU contains 512 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.When two power supplies are installed on
the same system and you want to remove
the 
Centml Processor Uirit jbm service,Bm power supplies MUST be turned off?
LEDs & Indicators
Three green 
LEDs located along the front
edge of the CPU provide an indication of the
presence of 
- 12V dc, + 12V dc & +5V dc. Twored 
LEDs provide the system heartbeat
indications.I/O Ports 
- Wiring/Pinouts/ConnectionsThe Central Processor Unit contains one
RS-232C, 8 pin modular jack type connec-
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. Refer to Figures 500-5
and 500-6 for additional information.

D. Voice Control Board 
(VCB)The Voice Control Board 
(VCB) provides
the time slot switch to control the digital
switching information. The system tones
are also generated on this board. The board
contains one 
DTMF receiver for DISA use.
LEDs h Indicators
There are two 
LEDs on the board to indi-
cate the 
+5V dc and - 5V dc.
Modem Interface
The Voice Control Board (VCB) contains an“On-Board” modem that is capable of
transmitting data at a rate of 1200 baud.
The modem supports and is compatible
with the Hayes command protocol.
The Bell System (Western Electric) stand-ards 103 and 2 
12A for design is incorpo-
rated into the design of this . The operateson-line in both Full and Halfduplexmodes.
Wiring 
/ Pinouts / Connections
There are two phono input connectors on
the board. One connector is for back-
ground music and the other is for music on
hold. There are also two potentiometers to
adjust each music source.

E.Key Telephone Board (KT12)
This board provides the interface to twelvedigital telephones. This board can be
plugged into any designated station slot.
Refer to Figure 500-S Key Telephone Board
(KT12) for location of connectors.
LEDs & Indicators
The board contains two 
LEDs to indicate
the presence of 
+5V dc and -5V dc. The
LEDs are located on the top portion of the
board.
Line/Station InterfacesThe board has one male 
50-pin amphenol
connector on the front edge. This will inter-
face the circuits on the board to the MDF.The card also provides proper fusing or
protection to comply with the requirementsof UL 1459 Second Edition and CSA C22.2
No. 225 standards.
A Digital DSS Console, a Single Line Tele-phone Adapter 
(OPX), or other specifically
designed adapter with a digital interface
can be assigned to any one of the interface
circuits. The Key Station interface circuitsare protected from mis-wiring and 
over-
current.
