3.1 C̲O̲N̲F̲I̲G̲U̲R̲A̲T̲I̲O̲N̲
The terminal equipment located in the Communications
Centre is listed in table 3.2-1 according to operator
positions. The equipment list includes government furnished
equipment, such as optical character reader and telex
terminals. The interfaces to the terminals are to the
greatest extend possible serial line interfaces (V24).
This provides for the maximum flexibility and allows
the user to exploit the full capacity of the delivered
interface units as well as allowing the cheapest modular
increase in interface capacity. Chapter 2 provides
a full description of the types of line interfaces
and the data sheets provides the details. Due to the
concept of standard interface, no maximum connection
capacity can be given per type of terminal.
Table 3.2-2 shows the Interface for the individual
terminals. All serial line interfaces are via LTU,
which can handle up to four terminals with the same
low level protocol (levels 1 and 2). The parallel and
special interfaces are directly dimensioned for the
individual terminal units, however, more interfaces
can be installed. The limitations to expansions are
governed by the maximum expansion of the ZVA.
But the central computer system can due to its extremely
good modularity be greatly expanded and this is particularly
true for the interface modules thereby giving the system
a total high connection capacity.
The standard serial line interface shall be in accordance
with V24/V28 standard. Christian Rovsing A/S has as
a standard option, long line low level serial adaptors,
which can be employed. These provide a driving distance
of 1000 m. These adaptors have also a very low EMI
Profile suited for stringent security requirements.
A third possibility for serial line communication is
fibre optic cables, which are fully secure and have
maximum legth of 2000 m.
The terminals offered can all function simultaneously,
and the ZVA is dimensioned to provide good response
time and through-put at simultaneous terminal use.
Note: the figures in this chapter are for guidance
only. In case of discrepancy, the equipment numbers
in the equipment delivery list are to be followed.
All the required technical data for the individual
terminal equipment types are provided in the data sheets
for the equipment as an appendix. This chapter provides
an overview of the types and their main features.
The availability of the service of individual types
of equipment is in general ensured by having more of
the same type and a possibility to redirect the function.
However, for units, where only one are delivered, i.e.
Line Printer, the service can be temporary suspended
or cannot, for the lineprinter, the printing could
be done on the document Printing System. Another possibility
is to change the specification to more than one unit
with a lower throughput, which would result in a degraded
throughput in case of unit failure.
3.2 T̲E̲R̲M̲I̲N̲A̲L̲ ̲E̲Q̲U̲I̲P̲M̲E̲N̲T̲
For the central processing of incoming and outgoing
information the following terminal input/output devices
are expected to be connected to the central computer
system in the communications centre. Subsequent paragraphs
show the configuration at individual locations.
Table 3.2-1 provides the overview of the terminal equipment
sorted according to location. Table 3.2-2 provides
a list of the equipment with total numbers and interface
specifications.
3.2.1 O̲p̲t̲i̲c̲a̲l̲ ̲C̲h̲a̲r̲a̲c̲t̲e̲r̲ ̲R̲e̲a̲d̲e̲r̲
The government furnished optical character reader,
Alphaword III+, will be the terminal device for scanning
typed messages. The interface to the central system
will be a serial V24 Interface.

The papertape readers are intended for input of:
1) Messages from Telexnet.
2) External encoded and decoded messages.
3) Test messages, inserts, redirected messages.
4) Crypto keys.
The advanced GNT 28 papertape reader in the 5 channel
version more than fulfill the requirements. The main
features are:
- reading speed up to 1000 chars/sec.
- high reliability
- easy loading
It is expected that the built-in control panel will
be sufficient for the tape input. The message control
is done through one of the VDU's.
The AA forsee only a requirement for the 5 channel
version of the GNT 28, should AA require one or more
8 channel units, these can also be delivered.
3.2.3 P̲a̲p̲e̲r̲t̲a̲p̲e̲ ̲P̲u̲n̲c̲h̲
The Papertape Punch Equipment provides output of the
following data:
1) Messages for Telexnets, not directly connected
to the central computer system.
2) Messages for external en/decoding.
3) Special messages, for external treatment.
The papertape punch equipment will consist of a set
of GNT 3601 Tape Punch Stations. See appendix for data
sheet. The individual stations have a punching speed
of 75 char/sec. and to meet the required throughput,
a complement of 4 would be required. This provides
the following advantages over three faster units:
1) More messages can be produced in parallel, which
is relevant with an average tape length of only
8m.
2) Higher availability due to more identical units
and better redirection possibilities.
3) Higher individual reliability, due to lower speed
and therefore less mechanical wear. Note: electromechanical
units are inherent less reliable than for example
computers.
4) Less noise due to lower speed.
In connection with the individual tapepunch units a
printer will be installed. See para 3.2.8 for description
of printer.
3.2.4 P̲r̲i̲n̲t̲i̲n̲g̲ ̲S̲y̲s̲t̲e̲m̲s̲
The printing systems installed in the Communication
Centre are of two types:
1) A fast line printer for in principle internal operationally
oriented information.
2) A document printing system for messages primarily.
3) Terminal printer, described in 3.2.8
Table 3.2.4-1 shows the major characteristics or the
reference to description of data for the individual
systems.

The fast line printer will be the Data products B-1000
Band Printer as described in the data sheet in appendix.
The B-1000 is a standard unit often used in the CHRISTIAN
ROVSING A/S systems and is one of a family of line
printers, the others being B-300, B-600, B-1500, B-1800.
the selected options are available for all the models,
see datasheets. The B-1000 offers high reliability,
good fount and is delivered with a sound proofing cabinet
for quit operations. The printing speed of B-1000 is
900 lines per minute. The printer provides 10 chars/inch,
136 chars wide, 6/8 lines per inch switchable. The
Appendix C provides a printing sample for the B-1000.
Through the standard CR80 operating system facilities
the individual information can be printed on the line
printer.
The control information between the printer and the
printer controller is shown in Appendix C, datasheets.
3.2.4.2 D̲o̲c̲u̲m̲e̲n̲t̲ ̲P̲r̲i̲n̲t̲i̲n̲g̲ ̲S̲y̲s̲t̲e̲m̲
The advanced computer controlled printing system with
online connection to the central computer system will
automatically provide the 3 functions: printing, copying
and sorting. The actual output of the message printing
system varies considerably betweeen the three dimensioning
years as well as between lower and upper limits. Based
on a busy hour of some 1400 pages, CHRISTIAN ROVSING
A/S offers the RANK XEROX 2700 laser printing system
with 2 parallel units, which provide for a graceful
degradation without reverting to manual operations.
More units will enhance this. Based on actual analysis
during the detailed specification phase an option of
adding more units exists.
The System provides an extremely wide range of typefaces,
inclusive teletex-vorm, in that the lase printing principle
allow for the generation of any figure on paper. The
size and orientation can also be varied and more than
fulfil the AA requirements to character spacing, line
spacing and positioning (right or left oriented). The
2700 offer only a front page printing on the DIN A4
page, the option, the 8700 can however print on both
sides.
The control of the printing system is done from the
host via a protocol based on escape characters. The
protocol allow for changing front (typeface), size,
position, left right or top/bottom margin, horizontal
or vertical printing and various other options. The
sorting is done by displacing the next copy left or
right from the previous copy; this is also effected
through escape sequence. The printing of the copy is
done through repetition of the whole sequence.
Font size tables, lines per page tables, error and
display code tables are attached in Appendix C.
The printing quality is extremely high as shown in
the sample print with various examples. The examples
also shown some of the type face possibilities. The
range of typefaces can futhermore be enhanced. The
paperquality is normal paper. The logical addressing
is expected accomplished with an addressing header
or page and a defined copy sequence.
The units are unique in that the sorting requirement
is integral in the system and is flexible with up to
500 addresses of 1 page each without any mechanical
changes. For the typical two page message the printer
can deliver 250 copies without manual support.
As an alternative the high capacity Rank Xerox 8700
Printing System can be included in the system. The
capacity is here some 3600 DIN A4 pages in the busy
hour.
Furthermore this system provides the facility of printing
on both sides of the paper. The printing system is
fully capable of being expanded with more units at
a later date corresponding to the increased traffic.
Note that the sample print is valid for both Rank Xerox
2700 and Rank Xerox 8700 since they employ the same
printing system and have the same resolution.
3.2.5 T̲e̲l̲e̲x̲ ̲S̲t̲a̲t̲i̲o̲n̲
The Telex Stations are government furnished equipment
of types T1000 and PT80. The Interface which for the
T1000 is described as "to be specified by customer"
is assumed to be CCITT V24/V28, in the cases where
the telexstation shall be connected to the Central
Computer System.
3.2.6 T̲e̲l̲e̲t̲e̲x̲ ̲S̲t̲a̲t̲i̲o̲n̲
The Teletex Station for communication to the Ttx lines
will be a Siemens T4200 Model 40 with CRT, printer
and keyboard. The Data Sheet is at Appendix C.
3.2.7 V̲i̲s̲u̲a̲l̲ ̲D̲i̲s̲p̲l̲a̲y̲ ̲U̲n̲i̲t̲ ̲(̲V̲D̲U̲)̲
The VDU for the system is the product: CR16.
The VDUs will be used for the following functions as
described in chapters 3 and 4:
1) System Supervisory Functions
2) Message Distribution Functions.
3) Message Service Function inclusive Message Editing
and Correction.
4) Radio Link Service.
5) Word Processing.
6) Office Support.
The keyboard in the tempest version will be equipped
with keylock, and software password is a standard feature
of the secure operating system. The individual operator
positions will furtermore enjoy the multiple independent
areas on the display, which provide for the CHRISTIAN
ROVSING advanced man-machine interface. The keyboard
is equipped with both fixed (FFK) and variable (VFK)
function keys for editing and for function selection.
The display screens will have adjustable tilt and the
keyboard is a physically separate unit.
The new modern CR16 Display with not only alphanumeric
capabilities, but also some graphic features. The advantages
of the CR16 Display System are the following:
- All display requirements inclusive graphics, word
processing and office support can be met.
- The CR16 is small and compact in design.
- The CR16 can be delivered with a keyboard to the
customers requirements inclusive keylock.
- The CR16 can be deliverd in a TEMPEST version (CR86T).
- The CR16 can be delivered with teletex alphabeth.
- The CR16 can be delivered with the teletex capabilities
(except printer).
Therefore the diverse requirements to the displays
can be met by one type of display hardware with flexible
firmware and reconfiguration capabilities.
The features relevant for word processing and office
support are described in chapter 4.
3.2.8 P̲r̲i̲n̲t̲e̲r̲
The printer for the system is for all operator positions
the Siemens PT88 Inkjet Version which fully meets the
requirements.The Inkjet Version is selected due to
the higher printing speed, the virtually maintenance
free operations and that printing is constant in the
lifetime of the ink cartridge. Attached in appendix
C is therefore only one sample of the printing quality.
Should the customer desire the needle-version of the
PT88, this can be accomplished without problems.
The PT88 has a simple interface protocol to the host,
see datasheet, appendix C. This poses no problem since
the system can sense error conditions by printer busy,
a host buffer is available and the printers located
next to an operator for his convenience. The detailed
specifications are given in the data sheets in the
appendix.
The speed of 150 character/second more than meets the
requirements for all applications In addition the PT88
is using the same operating principle for the Inkjet
Printing System as the PT80 already in use by the client.
The line spacing is programmable on the PT88 and can
therefore meet the requirements.
3.3 M̲E̲S̲S̲A̲G̲E̲ ̲R̲E̲G̲I̲S̲T̲R̲A̲T̲I̲O̲N̲ ̲O̲P̲E̲R̲A̲T̲O̲R̲
The CHRISTIAN ROVSING A/S System is based on similar
advanced military and civilian systems. The individual
operator positions in 3.3 to 3.8 are described according
to the RFP, but it is advised to adjust the definition
of the functions during the detailed specification
phase to take advantage of the hardware commonality
and the dynamic reassignment possibilities offered
in the system.
The message registration operator is a subfunction
of the message service functions or the message distribution
function and is treated accordingly in the software
description.
The hardware for the operator is one VDU, which can
be a physical VDU or any available position with a
VDU according to the preference of the client and the
system supervisor assignment.
The functions as well as the commands and system messages
are all a function of the detailed system specifications.
The described hardware as well as the software allow
for a very advanced user- system dialogue for the monitoring
and control, both of the system, and of the handling
of the message.
Furthermore due to the high speed of the VDU and the
serial line (9600 baud), the format requirements for
commands can be much more user oriented, written in
the correct user terminology and executed faster. Warnings
and messages to the operator can also be shown in clear
text without undue delay. Note that the 9600 baud provides
for approximately 1000 characters per second compared
to the required printer 30 characters per second.
3.4 M̲O̲N̲I̲T̲O̲R̲I̲N̲G̲ ̲A̲N̲D̲ ̲C̲O̲N̲T̲R̲O̲L̲ ̲O̲P̲E̲R̲A̲T̲O̲R̲S̲
The concept described in 3.3 covers also the monitoring
and control positions required in the following subparagraphs.
The indicated expansion requirement can always be met
by the offered system, but due to the dynamic reassignment
feature in the system the larger number of individual
positions might only be required at a fully expanded
system. The hardware requirements of the individual
locations are nevertheless described based on the client
stated hardware requirements.
Three types of monitoring and control functions are
required:
1) System Control and Monitoring.
2) Message Processing Control, Monitoring and Adminstration.
3) External Communications Control and Monitoring.
The individual positions are equipped with the CR16
with the multiple split screen concept, the operators
can therefore receive multiple alarms, warnings and
status data without a requirement that he interrupts
current activity. The total screen dialogue is of course
in german with minimal use of abbreviations and codes.
The optional printer on the other hand can record the
events as they occur, provide a record of all events
pertinent to the function without interfering with
the operator task, and without being interspersed with
operator commands. Furthermore the VDU- printer concept
allow for a modern man-machine interface with various
levels of operator support e.g. menu selection, fill
in the blanks, and help functions, all of which provide
for on the job training and support to the uninitiated
user.
3.4.1 S̲y̲s̲t̲e̲m̲ ̲S̲u̲p̲e̲r̲v̲i̲s̲o̲r̲ ̲(̲S̲y̲s̲t̲e̲m̲ ̲K̲o̲n̲t̲r̲o̲l̲l̲p̲l̲a̲t̲z̲)̲
The Technical System Supervisor has as the main purpose
the operational condition of the ZVA inclusive the
watchdog peripheral equipment, all workstations, all
external communication lines to modems, radio or external
lines.
Control of the total system is done from this position
through status display, summaries and direct commands
to redirect functions to different equipment and lines.
The equipment for the display and control is a CR16
VDU and a PT88 printer, where all changes in status
of any equipment and line as well as all actions are
printed with the associated time. Any change in equipment
status or workstation status or operator request of
a technical nature generate a message on the system
supervision queues. The message will be in clear text
and will also contain reference number, date and time.
The message will additionally indicate the required
actions possible.
The position described in 3.4.3, Netzuberwachungsplatz,
provide the external communication line status and
complement therefore the position.
The position will more than fulfil the stated requirements
relative to format, AA terminology, user friendliness,
flexibility and clarity as to type of message, e.g.
system warnings, standard messages, or action messages.
3.4.2 M̲e̲s̲s̲a̲g̲e̲ ̲D̲i̲s̲t̲r̲i̲b̲u̲t̲i̲o̲n̲ ̲O̲p̲e̲r̲a̲t̲o̲r̲ ̲(̲N̲a̲c̲h̲r̲i̲c̲h̲t̲e̲n̲k̲o̲n̲t̲o̲l̲l̲p̲l̲a̲t̲z̲)̲
The monitoring and control of the processing of incoming
and outgoing messages is done by this operator. The
functional description is covered in part II, paragraph
1.6.3 Message distribution operator (MCDO).
The position is ergonomically equipped with a CR16
and a parallel PT88 printer. The interactive process
as well as all incoming information is provided on
the VDU; the printer provides a log and action recording
(protokollierungsaufgaben). The messages of the position
will always refer to in- or out-going messages relative
to their reference number.
Especially the following functions are covered:
- retransmission of a message, possibly with repeated
encryption.
- encryption of a message, if required.
- papertape punching of a message for various reasons.
- deletion of messages.
- message distribution for corrective actions.
- message distribution.
The functions cover both treatment of incoming, outgoing
messages as well as general administrative tasks relative
to the message control.
3.4.3 S̲y̲s̲t̲e̲m̲ ̲S̲u̲p̲e̲r̲v̲i̲s̲o̲r̲(̲2̲)̲ ̲(̲N̲e̲t̲z̲u̲b̲e̲r̲w̲a̲c̲h̲u̲n̲g̲s̲p̲l̲a̲t̲z̲)̲
The system supervisory position provides the information
on the status of message handling system inclusive
all peripherals as well as the communications lines
connected to the system. The position is an extension
of the position (3.4.1). The supervisory position is
equipped with a colour graphic terminal, Intelligent
System Corporation 8001H, which is the standard display
in the general purpose CHRISTIAN ROVSING Process Control
System. The display is ideally suited for showing the
conditions of all lines and modules. The keyboards
can be used for the line control. The attached printer
PT88, can log all events for subsequent auditing. The
speed should be more than sufficient to cover for a
possible requirement of a second device (RFP).
As for other positions the position can be dualised
with additional graphic displays and printers, if required.
The detailed division of information between the colour
graphic terminal and the attached printer should be
done during the System Requirement Specifications.
The following functional description of display and
printer is therefore only tentative and not exhaustive.
3.4.3.1 C̲o̲l̲o̲u̲r̲ ̲G̲r̲a̲p̲h̲i̲c̲ ̲D̲i̲s̲p̲l̲a̲y̲ ̲F̲u̲n̲c̲t̲i̲o̲n̲s̲
The display functions as the interactive communication
device for the Network Supervisor. The following information
is shown:
- General status and functioning of
- ZVA
- Terminals
- Equipment
- Communication
- Logical control of system and components
- Status, Queue, Workload and traffic on:
- Equipment
- Network
- Message processing
- Printing
- Information on actions and events:
- Line switching
- Equipment and line outage
- Dialoque with the supovisor
- Function switching to any of the other positions
with their capabilities inclusive message processing
supervision.
- Routing changes and control
The presentation of the information and the possible
actions as well as actual actions and alarms is done
in combination of graphic, colour and alphanumeric
in the most user friendly fashion.
3.4.3.2 P̲r̲i̲n̲t̲e̲r̲ ̲F̲u̲n̲c̲t̲i̲o̲n̲s̲
The attached printer provides primarily the protocol
for all messages, events and actions relative to the
responsibilities of the Network Supervisor (Netzuberwachung)
i.e.
- System status changes
- System and configuration control
- Routing changes
- Summaries of information from other positions
- Action and event recording
- Logical control of system and components
The switching or redirection of the printer can be
done as for any othe terminal. Two possibilities exist
either locally controlled switching or from system
supervisor.
3.4.4 S̲e̲c̲u̲r̲i̲t̲y̲ ̲L̲o̲g̲ ̲(̲V̲S̲-̲t̲a̲g̲e̲b̲u̲c̲h̲)̲
The Security Log provides for an audit trail of all
incoming and outgoing messages of classified nature,
and all othe events and actions pertinent to the security.
The log will be done on a permanently coupled printer,
the Siemens PT88. The printout will be according to
the described layout with space for initials and later
amendments.
3.4.5 S̲i̲t̲u̲a̲t̲i̲o̲n̲ ̲M̲o̲n̲i̲t̲o̲r̲s̲ ̲(̲U̲b̲e̲r̲w̲a̲c̲h̲u̲n̲g̲s̲m̲o̲n̲i̲t̲o̲r̲e̲)̲
The overall system and communications situation is
displayed at multiple locations in the computer centre.
The means for the display is a set of BARCO colour
monitors (66 cm), type DCD 2740F. Since only a detailed
site survey and a subsequent equipment layout inclusive
the crypto equipment can substantiate the required
number of monitors, a minimum of 4 is assumed for the
proposal.
The pictures for the monitors can be taken from any
of the operator positions by slaving the monitors to
the displays. This is the method quoted in this proposal.
An alternative is to install a separate position (VDU),
on to which the required subset of messages can be
displayed independently of actions on the other positions.
(Not quoted).
A better alternative is to use a non interactive colour
picture generator with limited graphical possibilities
according to the video text system. All messages can
through this generator be displayed on the monitors
in various colours, for example based on type of messages,
Likewise for load conditions on the system can be shown

The terminal equipment for the operators consists of
CR16 VDUs. The allocation will be done from the system
supervisor or the Message Distribution Operator (MCDO).
These functions are described in part II, chapter 1.
The function will in general cover processing of incoming
and outgoing messages both real or exercise.
The functions also cover display of:
- Messages
- Corrective text
- Queues for incoming messages
- Quiuea for outgoing messages
- Interactive dialoque
The allocation of exercise stations amongst these are
also a function of the system supervisor and is in
line with the flexible system concept. Initially the
system will have 8 VDUs for these positions, later
16 VDUs.

3.6.1 I̲n̲t̲r̲o̲d̲u̲c̲t̲i̲o̲n̲
This chapter describes the Radio Control System, which
is to be used for control and monitoring of the 6 radio
channels from LKSAA to associated foreign offices (Auslandsvertretungen)
and others.
3.6.2 G̲e̲n̲e̲r̲a̲l̲ ̲D̲e̲s̲c̲r̲i̲p̲t̲i̲o̲n̲
The Radio Control System is divided in the following
subsystems:
a) Radio Control Center, located at AA Fernmeldezentrum
in Bonn
b) 2 Remote Receiverstations
c) 2 Remote Transmitterstations
The configuration of the system is shown in Figure
3.6.2-1.
To obtain a very flexible system, the Radio Control
System is configured around a X-Net. This will For
example allow easy extensions to fullfil a future requirement
of 2400 bit/s datacommunication instead of the present
requirement of 100 or 200 bit/s.
The use of the X-Net (Technical Proposal Volume II,
Section 2.1.2.1, and APPENDIX C, page 63)enables remote
monitoring and control of the equipment on the remote
sites and that datacommunication with all receivers
or transmitters on the site can be handled on one telephone
channel per site. Siemens 2400 DX Modems are proposed
for this purpose.
To obtain a high availability of the system major parts
have been dualized.
Basically the proposal is based on Full-duplex ARQ
or FEC communication.

The data communication to take place via the Radio
Control System will pass the Patch Facility (Schaltplatz)
and the Cryptos of LKSAA. The ZVA and the Crypto System
will control encryption and decryption of data (described
in the Technical Proposal Volume II section 3.9)
To communicate information concerning pending traffic,
length of messages, priority, identifications, etc.
a dualized communication line to the ZVA for this purpose
is included
3.6.2.2 P̲R̲O̲C̲E̲S̲S̲I̲N̲G̲ ̲I̲N̲ ̲R̲A̲D̲I̲O̲ ̲C̲O̲N̲T̲R̲O̲L̲ ̲S̲Y̲S̲T̲E̲M̲
The processing in the Radio Control System is handled
by the microprocessors of the intelligent CR 16 work
stations (Section 3.2.1).
The operators of the Radio Control System can interactively
control and monitor the equipment of the system.
Print outs relevant to the operation of the system
is performed on an associated Printer and Teletype.
3.6.2.3 B̲A̲C̲K̲ ̲U̲P̲ ̲F̲A̲C̲I̲L̲I̲T̲I̲E̲S̲
Due to the high availability of the system obtained
by the dualization of vital parts, special back up
equipment for the radio control system is not included.
Via the patch facility (Schaltplatz und Handvermittlung)
of LKSAA, teletypes can be connected to the datachannels
to give back up of the data communication in case of
ZVA failure. (see Technical Proposal Volume II, Section
3.9).

3.6.3.1 G̲E̲N̲E̲R̲A̲L̲
The configuration of the Radio Control Center is shown
in figure 3.6.3-1.
The Radio Control System supports the operator in his
tasks which includes
- setting up of links
- closing of links
- control of message transfer
- monitoring of message transfer
The Radio Control Center is situated in the basement
of the new AA building.
- To obtain an efficient system which requires only
a few telephone lines for exchange of data and
control and status information to be exchanged
with these sites, a dual X-Net configuration with
high reliability is used for multiplexing of remote
control functions.
- To obtain a system where failures only may affect
one channel, all common parts have been dualized,
both at the radio control site and the remote transmitter/receiver
sites.
Errors on the telephone line, the modem or the opto
couplers, through which all the multiplexed information
to one site shall pass, will however result in fall
out of all channels passing to that site. This will
be avoided by dualization of the telephone line modem.
Extra optocouplers to each site would be required.
The datatraffic to/from the ZVA will enter the Radio
Control System via the customer supplied combination
of ATS, FEC and ARQ, and a contractor supplied XTA
(X-Netz Terminal Adapter). An additional XTA is provided
to give interface to the Control and Monitoring part
of the ARQ. According to the datasheet V24 interface
is available for this purpose.
3.6.3.1.1 L̲i̲n̲k̲ ̲S̲e̲t̲-̲u̲p̲ ̲a̲n̲d̲ ̲C̲o̲n̲t̲r̲o̲l̲ ̲o̲f̲ ̲M̲e̲s̲s̲a̲g̲e̲ ̲T̲r̲a̲n̲s̲f̲e̲r̲
Link set-up takes place as described in 3.6 and 3.6.3.1.3.
The radio operator will check on his VDU the waiting
list of messages to be transmitted, select the highest
priority message and set-up the link as described in
3.6.3.1.2. When the link has been established, the
operator sends a command from the VDU keyboard to the
ZVA, therby activating the transmission of the message
via the established radio channel. This procedure is
fully compliant with the radio system requirement as
specified in "Klarstellungen" para. 3.1.2.1.6
= Customer supplied equipment

By manual set-up of the radio link, the operator and
his counterpart will exchange information relevant
to the set-up of the link by a dialogue performed on
the VDU (Bildschirm) or by morse keying. For this purpose
the operator must give a command to the system which
indicates whether a dialogue is performed or whether
the activiations on the morse key shall be transferred
to the transmitter.
When the link has been established, the operator will
issue a command to the system to activate the ARQ connection
and initiate message transfer. The operator at the
AA will normally issue the command for closing of the
link.
If the transmission of a message has been interrupted,
the Radio Control System will inform the ZVA, so the
whole message can be repeated next time a link to the
affected location in established.
3.6.3.1.3 A̲u̲t̲o̲m̲a̲t̲i̲c̲ ̲S̲e̲t̲-̲u̲p̲ ̲o̲f̲ ̲R̲a̲d̲i̲o̲ ̲L̲i̲n̲k̲s̲
The customer furnished ATS may be used to set up the
link, when communication with an unmanned location
is desired.
After the operator has established the link by use
of the ATS, a command is input to the Radio Control
System, which in turn will request the ZVA to transmit
messages which, according to their classification,
may be sent to that location.
The Software Control of the ATS from the VDU will be
implemented. The customer is assumed to provide an
interface with the ATS which is compatible with the
XTA controlling the ARQ/FEC System.
3.6.3.1.4 M̲e̲s̲s̲a̲g̲e̲ ̲T̲r̲a̲n̲s̲f̲e̲r̲
When the operator has indicated to the system that
a link is ready, the counterpart has to issue an open
identification before the ZVA will request the Crypto
System to load a key and perform Crypto Synchronization.
It is assumed that the equipment at the remote location
by itself can perform the equivalent switching of cryptographic
equipment in case of automatic set-up of the link.
After crypto synchronization is obtained, an additional
exchange of identification takes place. For transmission
of classified information on this may include a password.
When a link to a counterpart has been established,
all messages ready for transmissiion to that counterpart,
which may be sent in accordance with the present security
classification of the link, will be transmitted, unless
a STOP command is issued before the transmission has
been completed.
If the ZVA has no information or no more traffic to
the counterpart, to whom the link has been established,
a corresponding message will be sent.

Each of the 6 operator positions is normally allocated
to a specific radiochannel. Each of the positions is
equipped with a CR16 workstation (non-TEMPEST) with
colour graphic features (See Appendix C). This data
terminal has the same features as the CR86T except
the colour graphic features and the TEMPEST shielding.
Furthermore a special interface box is placed at each
position. This interface box gives connection to a
loudspeaker and the customer furnished morsekey and
headphone. The architectural design and installation
will be coordinated with the BBD.
In this box the position of the morse key is sampled
for regeneration at the corresponding transmitter.
The operator at each radio position (FP) can listen
to an analogue signal representing the original receiver
signal from the receiver corresponding to the selected
channel (on loudspeaker or headphones). For this output
a volume control is provided.
The picture of this signal will be representative for
the equivalent picture which would be obtained from
the receiver. The customer is assumed to provide a
signal on the V24 interface of the receiver, which
will be available for the XTA to transfer to the radio
control site.
3.6.3.2.2 V̲D̲U̲ ̲F̲u̲n̲c̲t̲i̲o̲n̲s̲ ̲(̲C̲o̲m̲m̲o̲n̲ ̲F̲u̲n̲c̲t̲i̲o̲n̲s̲)
From the VDU (Bildschirm) the operator can control
and monitor the equipment associated with the channel
allocated to that position. The screen is divided in
Status-fields, form-fields and free fields. The operator
can only make changes to the contents of the two latter.
The function keys of the keyboard will be allocated
to special funtions.
For the purpose of setting up a link, the operator
can request a form in which he can specify:
- Counterpart (name and call-sign)
- Transmitter and receiver frequencies
- Modulationtype for receiver and transmitter
- Orientation of transmitter antenna
- Bandwith of receiver
- Selection of receiver antenna (by number or direction)
Information, which has not been changed, need not be
specified again. Upon specification of the counterpart,
- the optimum frequency for the selected HF link, will
also be shown on the VDU of the corresponding radio
channel, if the operator requests this information
by a command from the keyboard.
The statistical data includes reliability figures for
the 99 different counterpart and 15 different frequencies
as function of time of year (spring, summer , autumn,
winter) and time of day. The optimum frequency for
the assigned radio channel will be shown on the VDU.
This information is also entered from any of the VDUs,
but due to the flexibility it will be possible at a
later time to extend the system so these data can be
entered directly from some other source. The frequency
can be changed either by entering the frequency on
the keyboard or by using special function keys (up
or down) allocated to slow and fast change of frequencies.
This function is generally available for all frequencies.
In the status fields the following information will
be shown:
- date and time
- channel status (free/occupied/during call/closing)
- status information received from receiver (RF input
level and FSK signal), transmitter, Antennarotor
and Antennamatrix
- ARQ status (transmit and receive disturbance, efficiency)
The status information most suitable for graphic presentation
(RF input level and FSK signal) will be shown as such,
and colours may be used to point out significant information.
The free field is intended for the dialogue with the
counterpart.
The waitlists which may be recalled by the operator
will list messages pending for transmission (all or
for a specific location)
This list will contain information on message number
receiving part, priority, expected time for transmittion
etc.
Before allocation to a link has taken place the duration
will be calculated by 100% efficiency. After the allocation
has taken place the actual efficiency will be calculated
together with the expected time for transmission, which
will be updated every minute based on actual efficiency.
The VDU will show the "expected time for transmission",
Link number and channel number.
The allocation of links to a channel and initiation
of message transfer for that link is performed by the
operator.

One of the positions, FP4 can additionally be nominated
as supervisor position. At this position all other
channels can be controlled and monitored, and the allocation
of channels to operator position may be changed.
The common bus system makes it possible to perform
the according allocation of all the equipment belonging
to one operator position at the same time.
The status (active, inactive, interrupted) of all 6
channels is displayed at the supervisor position.
A microphone and loudspeaker to be connected to the
intercom system is also placed at this position.
3.6.3.2.3.2 V̲o̲i̲c̲e̲ ̲(̲S̲o̲n̲d̲e̲r̲p̲l̲a̲t̲z̲ ̲F̲P̲6̲)
At FP6 a special program is scanning a number of channels
for incoming traffic. When an incoming call is detected,
the scanning is stopped automatically the signal is
validated and if the name or call-sign is recognized,
the operator will be informed by an acoustic signal.
The scanning starts again after identification of the
signal. The ID (identification) of the calling station
will be shown on the VDU.
Additionally the voice communication may take place
from this position. This requires additionally one
telephone line to the transmitter station and one telephoneline
to the receiver station.
For the purpose of the voice communication, this position
is equipped with a microphone.
3.6.3.3 R̲A̲C̲K̲S̲
2 Racks for ARQ, FEC , Modems, XTA's, XCT's, XCP'S
at the radio Control Center is included. These racks
are equipped with key lock on the doors.
3.6.3.4 L̲O̲G̲ ̲P̲R̲I̲N̲T̲E̲R̲
A common printer serves as log for all events pertinent
to the radio center. The printer connected to the ZVA
in the basic proposal is now connected to the Radio
Control System.
The log will contain
- Time for start and end of connection
- Number of received and transmitted characters
- Counterpart (name and call-sign)
- Channel number
- ARQ-value (average efficiency value for the duration
of the connection)
- Transmit and receive frequency.
3.6.3.5 T̲E̲L̲E̲T̲Y̲P̲E̲ ̲F̲O̲R̲ ̲R̲A̲D̲I̲O̲D̲I̲A̲L̲O̲G̲U̲E̲
The dialogue which the operator has performed via the
VDU with his counterpart during set up and closing
of the link, can be typed on a common teletype (customer
supplied) which is connected to the system.
3.6.3.6 B̲A̲C̲K̲-̲U̲P̲ ̲F̲A̲C̲I̲L̲I̲T̲I̲E̲S̲
Instead of a special back up facility, which would
require several telephone lines to the remote stations
and special equipment which could control the remote
equipment on an individual basis, a widely dualized
system is proposed.
By the degree of dualization implemented in the proposal,
most failures will only result in loss of one radio
channel. Only failures on telephone lines, modems and
optocouplers will result in loss of connection to one
complete site.
For even higher availability the telephone lines should
also be dualized.
This will require 8 extra optical modems at AA Central
Site.
3.6.3.7 S̲I̲M̲U̲L̲A̲T̲I̲O̲N̲ ̲F̲O̲R̲ ̲T̲E̲S̲T̲I̲N̲G̲
During the Factory Test it is necessary to simulate
transmitters, receivers and rotors. If this equipment
is unavailable at the time of installation, the simulation
equipment used for the factory tet will also be used
for final testing.
3.6.4 R̲e̲c̲e̲i̲v̲e̲r̲ ̲S̲t̲a̲t̲i̲o̲n̲
The configuration of a Receiver Station is shown in
figure 3.6.4-1.
Each of the 2 remote receiver stations is built around
a dualized X-Net, which acts as subbranch to the dualized
X-Net of the Radio Control Center.
By the selected dualization concept only failures of
the telephone line, modem and antennamatrix may affect
the operationalbility of the complete site.
Each Receiver Station is equipped to perform monitoring
and control of 4 receivers and 6 antennas.
The receivers and antennas are customer furnished.
For the control of the receivers, it is assumed that
the receivers can be remote controlled via V24 interface.
Racks for Receivers, Matrix, Modems and X-Net equipment
is included.
To select the operating antenna for the receivers an
KMX 6-4 antennamatrix is supplied. (see Appendix C,
page 196).
This antennamatrix contains separation amplifiers with
more than 40 dB isolation. The insertion loss is less
than 1 dB.
The output from the antennamatrix is independant of
the number of receivers connected to the same antenna.
From one of the receivers voice can be received. The
corresponding signal is connected to the Radio Control
Center via its own telephone line.
The control of the receivers and antennamatrix is performed
from the Radio Control Center, and available status
informations are transferred to the Center.

The configuration of a Transmitter Station is shown
in figure 3.6.5-1.
Each of the 2 remote Transmitter Stations is built
around dualized X-Net, which acts as subbranch to the
dualized X-Net of the Radio Control Center.
By the selected dualization concept only failures on
the telephone line and the modem may affect the operationability
of the complete site.
Each transmitter station is equipped to perform monitoring
and control of 4 transmitters and 4 antennarotors.
Transmitters, antennas and rotors are customer supplied.
Control and status to/from the transmitter is interfaced
via an XTA. For this purpose it is assumed that the
transmitters are equipped for remote control, and that
this interface is a V24 type. If a special interface
unit is required such unit could be designed for direct
interface to the X-Net.
To interface the rotors to the X-Net, an XTA and a
special Interface Unit is used.
The special Interface Unit contains 2 relays for control
of the motor, and A/D (Anglog/Digital) converter to
sense the orientation. Due to the noise performance,
the Interface Unit shall be mounted near the rotor.
The Voice signal for one of the transmitters is received
on a separate telephone line, and connected directly
to the A3 input of the transmitter.
The control of transmitters and rotors is performed
from the Radio Control Center, and the available status
informations are transferred to the Center. A Rack
for modems and X-Net equipment is included.

The Net Supervisor Function is one of the basic system
supervisory functions and can be allocated to any of
the available positions from the master system supervisor
console. If required, the position can employ the graphic
display for analysis of medium and long term planning
and control.
The Net Supervisor can control and change routing and
distribution list entries, as well as activate/deactivate
those.
The tables and transactions can be printed on any of
the printers, on the Line Printer or the Document Printing
System according to requirements and detailed specifications.
The format for the interactive control should be made
in the System Requirement Specifications. The full
interactive dialogue should be done based on the ergonomic
keyboard.

The switching of the Communication Lines and the Crypto
Units is illustated in figure 3.9-1. The switching
must employ two switching units to substitute a defective
Crypto-Unit with a spare. The red switching unit will
also provide the fallback or manual switching to individual
telex and teletex work stations. Additionally all switching
actions are printed on a log-printer.
A baseline solution is offered providing the basic
functions as a set of physical switching and patching
panels. In addition Christian Rovsing A/S has described
a completely electronic switching arrangement which
provides all required functions.

The Physical Units for patching, fallback- and bypass
switching are illustrated in figure 3.9.1-1 for a single
line with a spare Crypto-Unit. The switching function
between the Central System (ZVA) and the fallback telex
stations is accomplished through a set of fallback
switches which can be individually controlled or switched
together, see Red Fallback A/B on figure. Two sets
of patch panels on either side of the Crypto Units
(RED and BLACK) allow for a manual patching in of a
spare Crypto-Unit, should the normal crypto fail. The
patch panels are equipped with monitor access and a
monitor unit, which can be attached to any of the lines.
Additionally on both RED and BLACK sides of cryptos
a Bypass A/B switching panel is provided for the purpose
of bypassing the cryptos, when this is required on
Telex or Teletex Lines.
The switching of the Fallback A/S and/or Bypass A/S
switches will be controlled by the crypto system. The
switching of Fallback A/B can be performed independently
from the Bypass A/B switching for each channel or all
channels simultaneously.
Bypass A/B switching can likewise be controlled per
channel or all channels.
Switching commands will be issued by the ZVA to the
crypto system, which will send the proper ASCII command
to the switching panel.
The switching panel will acknowledge the command by
returning with the status of the channel switch to
the crypto system.
All switching actions will be recorded on the crypto
system log printer.
The only disadvantages are the lack of central electronic
control of patching and the lack of logging of patching
actions on a printing device.

The functions described in the customer requirements
can be realized through 2 X-Net facilities, a red (un-encrypted)
system and a black (encrypted) system (figure 3.9.2-1).
The black (c) X-Net would transfer the messages from
an input port (crypto or communication line) and electronically
transfer the message to the corresponding output port
(Communication Line or Crypto). In case of failure
on a Crypto only change of address would be required.
The red (A/B) X-Net would perform the same function
but between the Central Communication Unit (ZVA) and
the Cryptos. A telex station can be coupled to any
communication line solely through an address change
on the red X-Net. All activities can both be centrally
controlled and logged in the security log.
Further advantages of this electronic faciltity are:
(1) The Central Communication Unit (ZVA) needs only
to be implemented with a few high-speed interfaces
to the red X-Net.
(2) All Crypto-Units can be used to their full capacity.
(3) Speed Conversions can be done between Communication
Lines, Crypto Units, ZVA and individual telex and
teletex stations.
(4) A direct one-to-one correspondance between number
of communication lines and number of Crypto Units
need not to be established.
