1 S̲C̲O̲P̲E̲
This handbook constitutes the PC documentation, either
by descriptive sections (e.g. system overview, principle
or operation, and connection specification) or by references,
to the specific equipment manuals or to the applicable
superior CAMPS documents.
2 I̲N̲T̲R̲O̲D̲U̲C̲T̲I̲O̲N̲
2.1 S̲Y̲S̲T̲E̲M̲ ̲O̲V̲E̲R̲V̲I̲E̲W̲
In the following, the system and its relations to interfacing
systems are outlined and the characteristics of the
end-systems are described.
The three systems interfacing to the protocol converter
are:
a) CAMPS implemented on CR80 equipment
b) SCARS implemented on Burroughs equipment
c) CCIS implemented on Honeywell equipment
Transactions are required to be exchanged between any
two of these systems.
CAMPS and SCARS interface to the external environment
in the same way based upon an X25 protocol. These two
systems can therefore be interlinked directly without
involving the PC.
CCIS as implemented on a Honeywell 6000 configuration
with a DN 355 or a DN 6678 front end network processor
interfacing the external environment through the DINDAC
and RCI protocols. These protocols are incompatible
with the ones used by CAMPS and SCARS.
Thus, the objective of the protocol converter is to
provide a facility to support automated exchange of
transactions between CAMPS or SCARS on one side and
CCIS on the other side.
This objective is accomplished by connecting each end-system
to a converter which compensates for differences in
protocols in a way that allows the end system to operate
as if transactions were exchanged with a matching system.

2.4 F̲U̲N̲C̲T̲I̲O̲N̲A̲L̲ ̲P̲R̲I̲N̲C̲I̲P̲L̲E̲
The protocol converter shall exchange information between
the collocated Command and Control Information System
(CCIS), the Computer Aided Message Processing System
(CAMPS) and the Status Control Alerting and Reporting
System (SCARS).
One on-line Processor Unit (PU) is installed for each
link.
One off-line PU is available at each site for back-up
purposes. The off-line PU may be brought on-line by
manual replacement with one of the on-line PU's.
The Protocol Converter is able to support data transfer
between the end systems at up to 9600 baud line speed.
PC and the end systems are collocated and physically
connected by direct cabling.
The driving distance for the interface cables as seen
from the PC is up to 275 m.
The system connectivity is shown in Figure 2.4-1.
2.4.1 C̲A̲M̲P̲S̲/̲S̲C̲A̲R̲S̲ ̲I̲n̲t̲e̲r̲f̲a̲c̲e̲
The Protocol Converter is designed in such a way that
it can be used for signal lines from both CAMPS and
SCARS. PC to SCARS and CAMPS use a full duplex synchronous
electrical level using CCITT V24/V28 restricted by
NATO low level interface criteria.
2.4.2 C̲C̲I̲S̲ ̲I̲n̲t̲e̲r̲f̲a̲c̲e̲
The PC to CCIS interchange circuits are specified by
WWMCCS ADP telecom standards DCA for DN 355 and DN
6678 connections (reference q). I/O ports characteristics
are identical for DN 355 and DN 6678. For the PC to
CCIS interface, the electrical level will provide a
full duplex MIL STD 188C low level interface (reference
c).

3.1 S̲A̲F̲E̲T̲Y̲ ̲P̲R̲E̲C̲A̲U̲T̲I̲O̲N̲S̲
3.1.1 S̲a̲f̲e̲t̲y̲
All necessary safeguards have been taken during the
design, development, production and installation of
the equipment to ensure safety of operating and maintenance
personnel from electrical and mechanical hazards.
3.1.2 H̲i̲g̲h̲ ̲V̲o̲l̲t̲a̲g̲e̲
Where a high voltage is exposed during the maintenance
activities, this warning is provided:
Normal precautions concerning live electrical circuits
should be taken at all times when adjusting or servicing
this equipment or its peripherals.
This is applicable for the following equipment:
a) Power Line Filter
b) Mains Switch
c) Power Distribution Panel
d) S-Fan
e) Minicrate Power Supply
f) Adapter Power Supply
g) V.24 Test Panel
h) Maintenance VDU
3.1.3 L̲i̲g̲h̲t̲ ̲R̲a̲d̲i̲a̲t̲i̲o̲n̲
The major part of the light-power radiated from the
OPTO T/R module transmitters (OUT) are infra-red light.
Thus the visible-red light is n̲o̲t̲ representative for
the total light radiation!
According to safety regulations for infra-red semi-conductor
sources, the minimum safe distance from the source
to the eye is:
a) OPTO T/R transmitter/eye: 1 meter
b) End of opto-cable/eye: 0,5 meter
3.1.4 E̲q̲u̲i̲p̲m̲e̲n̲t̲ ̲S̲a̲f̲e̲t̲y̲
a) Circuit breakers or switches which operate to make
or break AC power lines shall make or break all
conductors at the same time. The neutral wire in
three-phase circuits shall not pass through any
fuse.
b) Fuses and circuit breakers are provided within
the equipment as required for protection of the
equipment from damage due to overload. Each major
assembly is individually protected so that a fault
in one major assembly cannot damage any other major
assembly.
c) All fuses and circuit breakers are located such
that they are readily accessible.
3.1.5 G̲r̲o̲u̲n̲d̲i̲n̲g̲
The grounding system provides effective protection
for personnel and material against insulation defects.
It is arranged so that there are three separate and
isolated ground circuits, namely:
1) AC power neutral
2) Equipment frame ground
3) Signalling and control ground
3.1.5.1 R̲a̲c̲k̲s̲ ̲a̲n̲d̲ ̲R̲a̲c̲k̲ ̲M̲o̲u̲n̲t̲e̲d̲ ̲E̲q̲u̲i̲p̲m̲e̲n̲t̲
a) The A̲C̲ ̲p̲o̲w̲e̲r̲ ̲n̲e̲u̲t̲r̲a̲l̲ provides a return for the
primary current so that the equipment frame ground
is used only to establish a safety ground and is
not used as a normal current grounding element.
No place in the equipment or power filters, the
AC power neutral is connected directly to equipment
frame ground.
b) The panel mounting rails are mounted in the rack
on insulating phenolic blocks and they are tied
together by ground wires. (E̲q̲u̲i̲p̲m̲e̲n̲t̲ ̲f̲r̲a̲m̲e̲ ̲g̲r̲o̲u̲n̲d̲)̲.̲
Thus, they form an insulated mounting frame in
the rack, where all equipment are grounded together.
A ground-wire connects the rack-mounted equipment
to the rack cabinet in one point. This point is
connected to the exterior ground wire connection
point.
c) The s̲i̲g̲n̲a̲l̲l̲i̲n̲g̲ ̲a̲n̲d̲ ̲c̲o̲n̲t̲r̲o̲l̲ ̲g̲r̲o̲u̲n̲d̲ are routed via
the interconnecting wires and cables as appropriate.
3.1.5.2 T̲e̲r̲m̲i̲n̲a̲l̲s̲

3.2.3 S̲e̲c̲u̲r̲i̲t̲y̲
This section addresses or references all requirements
related to security.
3.2.3.1 T̲e̲m̲p̲e̲s̲t̲ ̲P̲e̲r̲f̲o̲r̲m̲a̲n̲c̲e̲
The CR delivered on-line components of the PC equipment
are contained in an EMI shielded rack (except the VDU).
During short periods of corrective and preventive maintenance
e.g. open back doors, the emanation requirements are
degraded.
Operational procedures are required to ensure that
the supervisor is currently informed on activities
concerning corrective and preventive maintenance and
thus is able to decide whether it is acceptable to
continue operation or not.
a) The E̲M̲I̲ ̲s̲h̲i̲e̲l̲d̲e̲d̲ ̲r̲a̲c̲k̲s̲ used for CR delivered PC
equipment are manufactured for the same performance
as the EMI shielded racks used for CAMPS.
b) To meet the i̲n̲s̲t̲a̲l̲l̲a̲t̲i̲o̲n̲ ̲r̲e̲q̲u̲i̲r̲e̲m̲e̲n̲t̲s̲, the equipment,

I/O PORT LAY-OUT
a) The CPU part of the CPU-SCM module is a general
purpose processing unit with a 16 bit word length
and capable of addressing 2 x 64K words of memory.
The standard instruction repertoire has 274 basic
arithmetic, logic, transfer and special instructions
including bit, byte, word and multiple word manipulations.
Internal context registers include 8 general purpose
accumulator or index registers, a base register,
a program base register, a program counter, a timer
register, a process status word, and a modify register.
Instructions are addressed in 16 bit words. Data
may be addressed in multipla of bits, bytes or
words.
Two ALU's (Arithmetic Logic Units) are included,
allowing address and data manipulations to be performed
simultaneously. In the system mode, all instructions
in the instruction set can be executed and the
CPU has access to all main memory locations.
In the user mode, only a subset of the instruction
set may be executed, and access to parts of the
main memory is prohibited.
I/O interrupts are grouped in 4 priority levels.
Only interrupts with higher priority than the priority
of the process executing in the CPU are serviced.
I/O interrupts can either be handled by a user
defined micro-program or result in context switching
of software process.
b) The SCM acts as a supervisor for the CPU.
The SCM generates the timing signals necessary
for synchronization of the modules belonging to
the CR80 system.
Detecting and receiving of serially transmitted
I/O interrupt code are carried out in the SCM.
The two interrupt priority bits are fed through
to the CPU for control of process switching and
thereby fetching of the interrupt code in parallel
form. The SCM senses on the power lines, and generates
a power failure interrupt if a drop occurs.
The memory part of the SCM provides for the boot
strap loader and communicates with the CR80 system
via the main bus.
The SCM supports a serial I/O interface, asynchroneous/synchroneous
in full or half duplex.
Reception/transmission speed is determined by the
software. The following baud rates are available:
50, 75, 110, 134.5, 150, 300, 600, 1200, 2400,
3600, 4800, 7200, 9600, 19200 baud.
Parity is software selectable.
1, 1 1/2 or 2 stop bits are software selectable.
Electrical, mechanical, and logical the I/O slot
conform to CCITT V24/V28 recommendation.

3.3.1.6 L̲T̲U̲
The LTU is a CR80 standard 1M front module. The communication
with the CR80 computer is controlled by FIFO oriented
block transfer I/O commands decoded internally in the
LTU.
The CR80 interface is one part of the LTU, the other
one is the microprocessor part with the 4 communication
lines. The LTU has two RAM areas of 16K words. One
is the microprocessor program RAM, the other one is
a shared RAM between the CR80 interface and the microprocesssor.
The two parts communicate in this RAM area. The CR80
computer only has access to the shared RAM, therefore
it is necessary to have a bootloader (in a 2K PROM
area) to control the download of the LTU firmware from
the CR80 computer. See Figure 3.3.1-14.
The microcomputer is capable of handling higher level
protocols. For PC, X25 level 1, 2, 3, and RCI/DINDAC
are used.
The 4 communication lines can be served with a speed
of up to 9600 baud full duplex on each channel.
Immediately after power up, a selftest is started internally
in the LTU. This test can also be activated by pushing
a button placed on the board.
3 LEDs are mounted on the front panel.
POWER: green Indicates when +12, -12
and +5 power supply is
present at the module.
BOOTL: yellow Indicates when the LTU
is in bootload mode.
TEST: red If the LTU's selftest has
succeeded, the LED is turned
off. If failure, the LED
is flashing.

The LINE INTERFACE ADAPTER (LIA-N) provides the interface
between a Line Termination Unit (LTU) and four serial
V24 communication channels with a D25 connector each,
J1-J4.
As shown on the block diagram (Figure 3.3.1-17), all
signals between the LTU and the four serial communication
lines are running through a strap area.
No power connection is necessary since all received
and transmitted signals are according to the V24/V28
recommendations.
The LIA-N interfaces the LTU through a 64 pole flat
cable connection.
The standard application pin assignments are shown
in Figure 3.3.1-18 and in ref. i-1).
Four 25 pole standard D25 connectors provide the interface
to the serial communication lines. For special applications,
it is possible to change the signals to the connector
through strap-areas (SA1-SA4) on the module.
This is used to implement the configuration given
in ref. i-2), which supports the CAMPS/SCARS X.25 application.

The patch panel is a modular device consisting of a
front panel able to carry up to 13 patch modules, each
mounted in a shielding box.
Each of these patch modules supports 16 circuits as
shown in Figure 3.3.3-1.
The patch connector sockets are located on the front
panel while the D25 connectors are mounted on the back
of each patch module. Any channel may be monitored
by using the monitor socket.
The "normal-through" operation of the patch modules
eliminates patch-cables for standard connections. Figure
3.3.3-2 shows the patch module function.

3.3.3.2 B̲r̲e̲a̲k̲o̲u̲t̲ ̲T̲e̲s̲t̲ ̲P̲a̲n̲e̲l̲
The Breakout Panel enables a set of tests to be performed.
Each V24 circuit can be monitored by LED without interruption
of the signal path. Serial access to each digital line
is provided. Switches permit each lead to be exercised
to simulate "handshake" signals. A pulse trap is provided
which will latch and hold, until reset, if a polarity
change of duration greater than 3 microseconds occurs.
This model provides for 15 leads plus 1 unassigned
lead.
The diagram in Figure 3.3.3-3 indicates in simplified
form the interrelationship of the various parts of
each lead circuit. Provided on the same panel is +12
V, -12 V, ground and a 3K Ohm load to aid in circuit
testing. To help find and define short pulses, such
as responses to poll or line hits, the panel also includes
a pulse trap. This resetable circuit will detect, lock
and hold a pulse of either polarity. It is patched
into the lead in question with one of the patch cords
provided.
a) I̲n̲d̲i̲c̲a̲t̲o̲r̲s̲:
Each CCITT V24 circuit shown on the panel has a
tri-state (red-off-green) LED associated with it.
The LED's will turn on as follows:
More positive than +3 V RED
More nagative than -3 V GREEN
The area between -3V and +3V is considered undefined,
and the LED will be off for voltages in this range.
b) T̲e̲s̲t̲ ̲P̲o̲i̲n̲t̲s̲:
Each V24 circuit shown on the panel has two test
points associated with it. The top test points
are wired to the patch jack marked DCE. The DCE
jack is located at the left end of the test panel.
The bottom test points are wired to the patch jack
marked DTE. The DTE jack is located at the right
end of the test panel.
c) S̲w̲i̲t̲c̲h̲e̲s̲:
A switch is provided to open or close each of the
V24 circuits represented. All the leads will be
closed when all switches are in the up position.
d) P̲o̲w̲e̲r̲ ̲S̲u̲p̲p̲l̲y̲:
On the right side of the panel are nine test points;
three are available for +12 V DC and three are
available for -12 V DC. Both +12 and -12 V test
points are current limited and short circuit proof.
Two test points are wired to signal ground, and
one is wired to ground through a 3K Ohm resistor.
e) P̲u̲l̲s̲e̲ ̲T̲r̲a̲p̲:
This circuit will latch and hold (until reset)
when a 3 micro-second or longer duration pulse
occurs. The circuit will detect pulses of either
polarity.
f) I̲n̲p̲u̲t̲ ̲P̲o̲w̲e̲r̲:
220 VAC (+/-10%), 50 Hz, less than 30 watts.
Fuse: 1/4 amp slow blow.

The VDU is a Delta 7260 TC system consisting of a video
display screen and a keyboard.
The VDU is a system, in which each component is specially
shielded for security purposes. The terminal has two
vents on its rear side; an air outlet vent on the upper
section and an air inlet vent on the lower right section.
The AC fuse, AC power cord and backplane panel are
also located on the back of the terminal.
The keyboard connector is located on the lower right
front of the terminal, along with the power "ON" switch,
and control knobs for the bell tone, screen focus and
brightness (character and screen intensity).
The PCB card cage is found on the front of the terminal
just below the video screen and behind the keyboard.
The boards containing the circuits that enable the
VDU system to function are housed here.
On the front on the right side of the video screen,
a key-lock switch is located to prevent unauthorized
persons from using the VDU. The key-lock must be in
the ON position for the VDU-keyboard to be operational.
Inside the VDU the OPTO T/R, OM-1 is located in the
rear, right side. Refer to Figure 3.3.4-1
The dimensions of the terminal are as follows:
a. 492 mm wide
b. 730 mm long (depth of detachable keyboard,
279 mm, included)
c. 424 mm high
The terminal weighs approximately 34 kg.
The terminal has an air inlet vent along the bottom
left side.
