3.1.1 G̲e̲n̲e̲r̲a̲l̲ ̲D̲e̲s̲c̲r̲i̲p̲t̲i̲o̲n̲
The CAMPS Remote Terminals (CRT) system supports the
capability of moving some terminal operations from
the main sites to remote locations.
This does not mean that the max. connectivity of each
CAMPS-site as specified in ref. e) has been expanded.
The feature is obtained by means of statistical multiplexers
and customer supplied crypto/modem lines between main
and remote sites.
Thus 8 V24 channels connect each remote site to the
related main site.
The CRT equipment is contained in EMI shielded racks.
At the main sites the CRT rack(s) are bolted to the
main CAMPS Line Termination racks and form a 4 or 5
bay configuration, except Site 10 where a stand alone
rack is used.
3.1.2 F̲u̲n̲c̲t̲i̲o̲n̲a̲l̲ ̲R̲e̲q̲u̲i̲r̲e̲m̲e̲n̲t̲s̲
The remote terminal concept shall provide the following
possibility:
The transmission shall consist of 8 channels connecting
each remote site with the related main site.
The communication between each remote site and its
main site shall use a single multiplexed link.
3.1.2.1 R̲e̲m̲o̲t̲e̲ ̲S̲i̲t̲e̲ ̲C̲o̲n̲n̲e̲c̲t̲i̲o̲n̲s̲.̲
A single channel is saved for an OCR-option while the
7 channels are used as follows:
a) Primarily the 7 channels are used for transmission
of CAMPS-channels (connection to CAMPS expansion
or CRT LTUX at main site).
At the remote site 4 of these channels are terminated
with OMDTs for opto-cable connection to the terminals,
and 3 are terminated with V28(L/L) adaptors for
connection with electrical cables (auxiliary channels).
b) Secondary (option 1) it shall be possible to implement
a changed configuration, where the 3 auxiliary
channels are disconnected from CAMPS at the main
site and used as separate channels.
3.1.2.2 M̲a̲i̲n̲ ̲S̲i̲t̲e̲ ̲C̲o̲n̲n̲e̲c̲t̲i̲o̲n̲s̲
At the main site the remote terminal equipment shall
include one LTUX per remote site (4 channels).
a) Primarily these 4 channels are connected to the
stat.mux. and used for transmission to the remote
site.
b) Secondary (option 2) it shall be possible to implement
a changed configuration, where the stat. mux. is
disconnected, and the LTUX channels are used for
expanding the number of connected terminals in
the main site. The terminal connection points thus
made available shall have an optical interface.
3.1.3 D̲e̲s̲i̲g̲n̲ ̲R̲e̲q̲u̲i̲r̲e̲m̲e̲n̲t̲s̲
a) The system design shall be such that the same hardware
can be used to provide the required capability
at any of the installations.
b) The equipment provided at all installations covered
by this specification shall differ from one another,
if at all, only in the number of hardware units
of any given type in each configuration.
c) An operating CRT link includes both CR delivered
and SHAPE supplied equipment. The division of responsibility
of the equipment is defined by the responsibility
demarkation line, which will be on the feed-through
connectors mounted in the filter box. This applies
both on main sites and remote sites.
3.2 F̲U̲N̲C̲T̲I̲O̲N̲A̲L̲ ̲P̲R̲I̲N̲C̲I̲P̲L̲E̲
3.2.1 B̲a̲s̲i̲c̲ ̲C̲o̲n̲f̲i̲g̲u̲r̲a̲t̲i̲o̲n̲
Fig. 3.2.1-1 shows the configuration of a typical CRT-link
between a main site and its related remote site(s).
All CR supplied CRT-equipment are contained in separate
racks at the main site and remote site.
3.2.1.1 M̲a̲i̲n̲ ̲S̲i̲t̲e̲ ̲C̲o̲n̲f̲i̲g̲u̲r̲a̲t̲i̲o̲n̲
a) The connection to main CAMPS is obtained by means
of CTX crates, equipped with TDX-modules, connected
to the TDX-busses of CAMPS.
b) The statistical multiplexer multiplexes 8 V24 channels,
of which normally 4 channels are obtained from
the CRT-LTUX, 3 are auxiliary channels, which
are obtained from CAMPS expansion LTUX, (wherever
possible), and the last is reserved for a future
positioning of an OCR at the remote site.
c) The stat.mux. takes care of:
1) C̲h̲a̲n̲n̲e̲l̲ ̲m̲u̲l̲t̲i̲p̲l̲e̲x̲i̲n̲g̲. Statistical multiplexing
gives an improved modem line utilization compared
to none or conventional time division multiplexing.
2) T̲r̲a̲n̲s̲m̲i̲s̲s̲i̲o̲n̲ ̲e̲r̲r̲o̲r̲ ̲p̲r̲o̲t̲e̲c̲t̲i̲o̲n̲ by means of a
cyclic redundancy check and automatic retransmission
request on errors.
3) T̲r̲a̲f̲f̲i̲c̲ ̲f̲l̲o̲w̲ ̲c̲o̲n̲t̲r̲o̲l̲, which takes care of possible
data peak load effects by controlling the sending
activities of the data terminal equipment.
d) The mux-line of the stat.mux. is connected to a
feed-through connector in the filter box (responsibilities
demarkation line).
e) The mux. line is connected by customer supplied
wiring from the filter box to the red patch jack
field in the crypto room. In the crypto-room customer
supplied equipment takes care of encryption and
modulation of information to be transmitted through
the transmission media to the remote site and the
reverse function for information received from
the remote site.
3.2.1.2 R̲e̲m̲o̲t̲e̲ ̲S̲i̲t̲e̲ ̲C̲o̲n̲f̲i̲g̲u̲r̲a̲t̲i̲o̲n̲
a) Purchaser supplied equipment performs the same
function as described in 3.2.1.1.e) on information
received from/transmitted to the main site, ending
up with the mux line interface in the filter box.
b) The stat.mux demultiplexes the message and the
channels are connected to V28(L/L) adaptors and
Opto Mux/Demux Transceivers (OMDT) respectively.
c) The output of these devices leaves the EMI shielded
rack through the filter box.
d) The opto channels are connected to
1) the CR supplied Delta VDUs and/or
2) the CR supplied TRACOR medium speed printers.

3.2.2.1 O̲p̲t̲i̲o̲n̲ ̲1̲
a) Purpose: It shall be possible to implement a changed
configuration where the 3 auxiliary channels
are disconnected from CAMPS at the main
site and used for separate channels.
b) Design: The option is implemented by addition of
V28(L/L) adaptor equipment on the main
site.
These added adaptors (and crates etc.)
may be placed in the rack during normal
operation. Thus, a configuration change
is implemented by adding the needed cables.
3.2.2.2 O̲p̲t̲i̲o̲n̲ ̲2̲
a) Purpose: It shall be possible to implement a changed
configuration where the stat.mux is disconnected
and the LTUX channels are used for expanding
the number of connected terminals in the
main site. The terminal connection points
thus made available shall have an optical
interface.
b) Design: The option is implemented by adding opto
power supplies to the CRT TDX-crates assemblies.
The OMDTs can not be placed in the racks
during normal operation, so the option
may be implemented by transferring the
remote site OMDTs to the main site along
with the terminals.
Thus, a configuration change is implemented
by removing the unwanted cables, transferring
the OMDTs and adding the needed opto-cables.
3.2.3 I̲n̲t̲e̲r̲f̲a̲c̲e̲ ̲C̲a̲p̲a̲b̲i̲l̲i̲t̲y̲

This chapter presents a more detailed description of
the different H/W assemblies which have been identified
in chapter 3.
To provide a more comprehensive understanding of the
Remote Terminals System, each of the assemblies are
broken down into basic functional elements (i.e. crate,
buses and modules), and each of these is given a detailed
functional/mechanical description. The equipment is
divided in two major assemblies:
1) The main site equipment
2) The remote site equipment
5.1 M̲A̲I̲N̲ ̲S̲I̲T̲E̲ ̲E̲Q̲U̲I̲P̲M̲E̲N̲T̲
The aim of the equipment positioned at the mainsite
is to collect the datachannels for connection to the
remote site and perform the necessary multiplexing/demultiplexing
to enable communication via a single data link.
The datachannels may originate from
1) A LTUX belonging to the CRT equipment and connected
to the TDX-bus of CAMPS
2) CAMPS data channel expansion capacity (Expansion
LTUXs)
3) Separate channels interfaced via the CAMPS filterbox
4) A single data channel reserved for future connection
to a LTUX capable of handling an OCR
For the purpose of point 3) above a low-level signal
adaption capability is necessary.
The major functional subassemblies used on the Main
Site are shown in fig. 5.1-1::
1) TDX crate assembly

(An addressable UART) is the TDX Crate Assy interface
to the CAMPS Watchdog.
Fig. 5.1.1.2-1 shows the BSM-X principle diagram.
The Bus switch circuitry, selecting one of the dualized
TDX buses as the internal TDX bus, is controlled either
by the CAMPS Watchdog Processor or by a switch on the
BSM-X front panel. The source of control is selected
via another front panel mounted switch selecting either
Automatic mode, enabling Watchdog Processor control,
or Manual mode enabling manual TDX bus selection.
The BSM-X is a standard CR80S front crate module occupying
1 crate position.

5.1.1.3 L̲T̲U̲X̲-̲S̲
The LTUX-S is the standard interface to the TDX bus.
The LTUX-S provides 4 V24/V28 communication channels.
On the front panel are four switches that can be used
to enable/disable each of the four communication channels.
The LTUX-S is built around a standard microprocessor
using standard microprocessor interface LSIs as interface
between the TDX bus and the user applications.
5.1.1.3.1 T̲D̲X̲ ̲B̲u̲s̲ ̲I̲n̲t̲e̲r̲f̲a̲c̲e̲
The LTUX-S provides up to 16 full duplex individual
logical channels between the user application and the
TDX bus. The microprocessor supports both application
processing of the TDX interface, TDX protocol and TDX
channel set-up. The sum of bandwidth assigned to the
logic channels through the LTUX-S is dynamically changeable
by the CAMPS System.
Overleaf is found the block diagram of the LTUX-S,
fig. 5.1.1.3.1-1.
The TDX bus signals are buffered, by bus receivers
and a tri-statable driver, before they are routed to/from
the code converter circuit. In this circuit the incoming
SPL-D data stream is converted to NRZL data and a clock
(CLK). The outgoing data stream is converted to SPL-D
code synchronized to CLK. When an incoming frame is
received, the State Controller gets a request from
the serial to parallel converter and the contents of
the frame is routed byte by byte to FIFO 1.
During this transfer some of the bytes in the frame
are checked or compared "on the fly" by the State Controller.
The contents of the MUX no. field, indicating the next
device to transmit, is compared with the device number
(set on a DIL-switch), and if equal and no CRC errors
are detected the transmitter part is activated and
a frame will be transmitted when bit 241 of the incoming
data stream has been reached.
FIGURE 5.1.1.3.1-1…01…T̲H̲E̲ ̲L̲T̲U̲X̲-̲S̲
The contents of the DEVICE NO. field, indicating the
destinee of the frame, is compared to the device number,
and if equal the contents of FIFO 1 is transferred
to FIFO 2. If FIFO 2 is not empty this transfer is
cancelled and FIFO 1 is cleared to be ready for the
next incoming frame. When the transfer from FIFO 1
to FIFO 2 has succeeded the LTUX-S CPU is interrupted.
The interrupt routine (FRAME-routine) transfers the
frame from FIFO 2 to a free ringbuffer within the CPU
memory space, and the Incoming Scan routine transfers
the frame from the ringbuffer to a data buffer associated
to one out of ten protocol descriptors identified by
the CR-ID block in the incoming frame and simultaneously
executes the TDX protocol on the frame. Via the protocol
descriptor the frame is fetched by either the System
S/W (channel 0-1) or by Application S/W (channel 2-15).
Transfer is shown schematically on fig. 5.1.1.3.1-2
(2 sheets).
When the transmitter part of the State Controller has
been activated by an incoming frame, it starts to send
the start-FLAG followed by the frame which is transferred
byte by byte from FIFO 3 to the parallel to serial
converter. After the last byte an end-FLAG is generated,
the CPU is interrupted and will now move the next outgoing
frame from a channel buffer in the memory to FIFO 3.
If no frame is available the CPU does nothing and the
next time the transmitter is activated FIFO 3 will
be empty and no frame is transmitted.
The frame to be transmitted comes from a data buffer
fetched, via a protocol descriptor, by the Outgoing
Scan routine and routed to FIFO 3 directly while executing
the TDX protocol on the frame.
The processor part consists of a PROM-memory area,
a data memory area, serial input/output interface circuits
for four V24 channels, a timer and interrupt control
circuit and an I/O port used for reading a mode select
switch (DIL-switch) and for control of the State Controller.
The mode select switch can be used by the Application
S/W. For example to determine characteristics of the
V24 channels such as:
- baudrate
- V24 protocol

with interrupt access to the CPU. It handles one external
interrupt from the State Controller and it controls
two baud rate generators set up by software.

The CR supplied statistical multiplexer features full
duplex statistical multiplexing of 8 V24 channels,
with variable length block transmission, dynamic bandwidth
assignment and error control.
It is housed in a 19" rack-mount case 2U high (8,9
cm).
The status display is visible through the front panel
and all switches are front accessible after removal
of the front panel.

The transmission between the statistical multiplexers
is carried out by a special statistical multiplexer
serial communication protocol.
The channel interface control signals are transmitted
via the protocol in form of a special control character,
generated each time one of the control signals changes
from On to Off or vice-versa. Two interface control
signals may be transmitted in each direction per channel.
The transmisson of variable length data blocks according
to the loading of the individual channels, allows the
stat. mux. to take account of average traffic loading
on the mux-line, since it can make use of its buffer
storage to accomodate temporary peak loading on individual
channels.
5.1.3.2 E̲r̲r̲o̲r̲ ̲C̲o̲n̲t̲r̲o̲l̲
Retransmisson on error is implemented automatically
between the stat. muxes using a full-duplex go-back-n-automatic-retransmission-request
(ARQ) scheme. The transmitting stat. mux. appends a
cyclic redundancy check (CRC) scheme. The transmitting
stat. mux. appends a cyclic redundancy check (CRC)
character to each transmitted data-block in the protocol.
This CRC is re-calculated to check the block errors
at the receiving stat. mux.
5.1.3.3 B̲u̲f̲f̲e̲r̲ ̲C̲o̲n̲t̲r̲o̲l̲
The buffer capacity (approximately 15K bytes) is allocated
dynamically to the channels as required, rather than
being fixed portions.
However, buffer overflow may occur, either because
of excessive retransmissions or prolonged peak channel
activity. If a buffer overflow is about to occur, the
stat. mux terminates the flow of data into its buffer,
by dropping the circuit 106 control signal on the V24
channels to the associated equipment.
5.1.3.4 C̲o̲n̲f̲i̲g̲u̲r̲a̲t̲i̲o̲n̲
All configuration parameters are switch selected using
DIP switches to configure the units. To further simplify
system configuration, switch selection of configuration
parameters is required at one site only. This is done
by switch selection of master and slave on each unit.
All configuration data is then automatically down-line
loaded from the master to the slave unit, at power-up
or reconfiguration of channels.

The TDX, Opto and Adaptor Crate assemblies are cooled
by the CR80S fan assembly, see fig. 5.3.1-3.
The fan assembly is used for cooling of two CR80 S
crates placed one above the other with the fan assembly
placed below as shown on fig. 5.3.1-4.
The air intake is at the front of the fan assembly
and air is blown up through the front crate of the
CR80S crates.
The output air stream is directed backwards and will
leave the rack through perforations in the top plate
cover of the rack.

For further description see section 5.1.3/5.1.4.
5.3.2.2 P̲o̲w̲e̲r̲ ̲L̲i̲n̲e̲ ̲F̲i̲l̲t̲e̲r̲
The power supply lines are entering the racks through
power line filters for protection against noise and
spikes on the power lines.
A power line filter is designed as a box placed on
the inside surface of the rack wall and forming a cavity
in the EMI surface.
Power line filters used for CRT are placed in CAMPS
Line Termination Rack E in multibay configurations.
On remote sites and mainsite 10, a powerline filter
is included in the stand alone rack.
5.3.2.3 M̲a̲i̲n̲s̲ ̲S̲w̲i̲t̲c̲h̲ ̲A̲s̲s̲e̲m̲b̲l̲y̲
a) The main switch assembly are placed in the front,
bottom position of all racks.
Power switches and elapsed time indicators are
placed on the front panel. The mains switch is
a dual single-phase assembly sourced from the Power
Line Filter.
b) On Main Site 10 (UKAIR) the Main Switch Assembly
performs a step-down transformation from 240 VAC
to 220 VAC.
5.3.2.4 P̲o̲w̲e̲r̲ ̲D̲i̲s̲t̲r̲i̲b̲u̲t̲i̲o̲n̲ ̲P̲a̲n̲e̲l̲

the assemblies of the rack.
5.3.2.5 F̲i̲l̲t̲e̲r̲ ̲B̲o̲x̲ ̲A̲s̲s̲e̲m̲b̲l̲y̲
All V24 channels to external equipment are passed through
the Filter Box facility of CAMPS Line termination rack
F in multi-bay configurations. On remote sites and
main site 10 a filter box is included in the stand
alone rack. The principle of the Filter Box design
is shown on fig. 5.3.2-1.
The Filter Box forms a cavity in the EMI shielding
surface of the rack.
Electrical cables are conducted from the assemblies
containing V28(L) adapters to a position at the Filter
Box, where a feed through connector, containing RF-filters,
passes the signals through the EMI shield, formed by
the rack.
Opto cables are passed through the waveguide of the
Filter Box in the stand alone racks.
All signal cables are leaving the rack through the
attached cable duct.
A cover has to be removed to get access to the connectors
of the external electrical cables.

5.3.3 E̲M̲I̲ ̲S̲h̲i̲e̲l̲d̲e̲d̲ ̲R̲a̲c̲k̲s̲
A CRT Main Site Installation includes 1 or 2 Racks,
named Rack G and H. The CRT Remote Site Installation
includes a single rack.
The Racks serve 2 major tasks.
a) They contain a 19" Rack-system for mounting of
assemblies, units, and cables.
b) The rack assemblies provide an EMI shielding to
reduce electromagnetic radiation from the enclosed
equipment.
Fig. 5.3.3-1 shows a single rack. The max. dimensions
shown give the maximum envelope of the rack.
The rack has 2 doors, a front door and a rear door.
The front door allows full access to the mounted equipment.
Front and rear door are of equal size and are hinged
at the same side of the rack.
The doors and the cabinet are made of steel.
Two perforated areas in the front door allow air intake
for cooling of equipment. The top cover plate of the
cabinet is perforated to allow output of cooling airflow.
The gaps between doors and cabinet are blocked by gaskets
of conducting material.
The tightness of these gaskets is important for TEMPEST
performance. The gaskets are wear-out items with a
3 to 5 year service lifetime.
The 19" panel mounting rail system included in the
cabinet is mounted on insulation blocks and the mounted
equipment is thus galvanically insulated from the EMI
Shield.
The "useful depth" of the rack is the distance between
the mounting surfaces of the front and rear mounting
rails. The useful depth is 101 cm.
FIGURE 5.3.3-1…01…S̲I̲N̲G̲L̲E̲ ̲E̲M̲I̲-̲R̲A̲C̲K̲,̲ ̲D̲I̲M̲E̲N̲S̲I̲O̲N̲S̲
5.3.3.1 S̲t̲a̲n̲d̲ ̲A̲l̲o̲n̲e̲ ̲R̲a̲c̲k̲s̲
The stand alone racks are used on all Remote Sites
and on Main Site 10 (UKAIR).
The stand alone racks have side walls welded to the
cabinet to form one continuous EMI shield, when doors
are closed.
The stand alone racks have provisions for 6 knock-outs
in the top cover plate. All cabling (power and data
channels) will enter the stand alone racks in the top.
A schematic of the top cover plate is shown in fig.
5.3.3-2.
5.3.3.2 M̲u̲l̲t̲i̲-̲B̲a̲y̲ ̲R̲a̲c̲k̲-̲A̲s̲s̲e̲m̲b̲l̲y̲
At all main sites, except no. 10, the racks containing
the CRT main site equipment will be connected to the
CAMPS Line Termination Rack Assembly to form a multi-bay
rack. These multi-bay racks consist of single racks,
bolted together with conducting gaskets inserted. No
side walls are mounted between neighbouring racks.
When the doors are closed the multi-bay rack forms
one continuous EMI shield. The racks to be assembled
in a multi-bay configuration have provisions for 3
knock outs in the top cover plate and 3 in the bottom.
However they will not be used in the standard CRT design,
as the cabling normally will enter through the CAMPS
Line Termination Racks.
5.3.3.3 P̲o̲w̲e̲r̲,̲ ̲H̲e̲a̲t̲,̲ ̲a̲n̲d̲ ̲W̲e̲i̲g̲h̲t̲
In fig. 5.3.3.3-1 is shown the phases of Start-up.
a) Initial peak period.
In the initial period the current is defined by
initial currents due to saturation in transformers
and load currents for capacitors.
Period length and current waveform are depending
on the characteristics of the power source as well.
Peak current values of 10-50 times the current
value in use and a period length less than 100
ms are expected.
The power line filters inserted on the power lines
entering the equipment room will influence the
initial peak period.
b) S̲t̲a̲r̲t̲ ̲P̲e̲r̲i̲o̲d̲
The start period is defined by the start-up of
AC-motors in the racks.
AC-motors are used in Fan assemblies.
The start period will be in the range 2-20 secs.
c) U̲s̲e̲ ̲P̲e̲r̲i̲o̲d̲
Use period characteristics are the characteristics
of the equipment in normal use after termination
of start-up phenomena.
The power and weight data of the individual racks are
tabulated in fig. 5.3.3.3-2.
The values shall be considered as typical.

The panel mounting rails in the racks are mounted insulated.
Thus, all equipment in one rack is grounded together,
but basically insulated from the exterior rack.
A ground-wire connects the rack-mounted equipment to
the rack in one point. This point is connected to the
exterior ground wire connection point.
When more racks are joined to form a multi-bay rack
assembly, they are connected around the joining perimeters
to form one continuous cabinet. In the cabinet the
rack mounted equipment is connected to one common point.
This point is connected to the exterior ground wire
connection point of the cabinet.
