The decision to bid IDCN as Sub Contractor to ELBIT
represents a definite commitment on the part of Christian
Rovsing A/S to devote its resources and technical talents
to the successful implementation and performance of
the system. The decision was taken at toplevel after
thorough discussions with the staff of marketing, administration,
and engineering at Christian Rovsing A/S.
Considerable experience in the field of data communication
combined with experience as prime manager of major
computer system projects provide a solid basis for
our participation in this project. Prime contractor
responsibility, particularly for military customers
such as NATO-SHAPE, has demanded a professional approach
to turn-key project management with particular emphasis
on planning and documentation in all phases from system
design and development to production, integration,
installation, training, and maintenance. The contracts
awarded to the company have been typically worth from
several to tens of millions of Dollars.
To provide the necessary talent and facilities, the
IDCN project will be staffed by experts from all divisions
at Christian Rovsing A/S. Thus, exceptionally strong
capabilities will be available in computing and data
communication.
Participating entities at Christian Rovsing A/S are:
o The Systems Division - structured in 1979 to consolidate
management of major computer system projects. The
CAMPS project for NATO is the responsibility of
the Systems Division.
o The Development Division - responsible for the
design of the CR80 Computer product line of which
more than 200 systems are currently on order from
major customers such as NATO, ICL and L.M. Ericsson.
o The Production Division - responsible for manufacturing
of the CR80 Computer product line.
The IDCN Project Group will be supported by the Christian
Rovsing A/S, Integrated Logistics Support Group, which
provides services including site surveys, installation,
training, documentation preparation, maintenance, spares
and other necessary support services.
Product quality will be ensured by the Quality Assurance
Department, which reports directly to company management.
An administratively distinct Project Office will be
established to manage the IDCN Project. This project
office will have total system responsibility and authority
to coordinate in-house activities and to provide close
liaison with the Main Contractors throughout the duration
of the project.
In summary, the decision to bid is based on the confidence
that Christian Rovsing A/S and ELBIT have all the necessary
qualifications for the successful design, implementation
and maintenance of the IDCN.
The processor for the message handling and communication
system is similar to the highly efficient communications
processor used in the FIKS program and also to be used
in extensive airline communication systems like Air
Canada's and American Airlines', where up to 65,000
terminals will be connected to various host computers.
All the Node computers proposed for the IDCN are fully
dualized CR80 computer system, with automatic switch-over
from active to the standby in the event of failure.
Manual switch-over is also possible to accomplish "on-line"
maintenance, i.e. maintenance without loss of function
by using the standby unit for processing while the
formerly active unit is serviced. In addition to fault
tolerant operation and ease of maintenance, the CR80
is characterized by high performance, high system availability,
and growth by simple addition of standard modules.
Christian Rovsing A/S's experience with interfacing
to crypto system is based on various military projects
conducted in the past. Especially in the Integrated
Danish Military Communication System, FIKS, Christian
Rovsing A/S has - in close cooperation with the customer
- designed a unique, very cost effective and secure
crypto system. Christian Rovsing A/S believes that
a similar approach could be taken on the IDCN if so
desired by ELBIT.
The IDCN system design will benefit from experience
gained in the FIKS program, which have been supplied
by the Christian Rovsing A/S and fully accepted by
Danish Military. These elements will provide an important
no-risk aspect to the proposed IDCN Network. Figure
1.1-1 gives an overview of the IDCN Network.

The IDCN will meet all requirements for speed, capacity,
security, reliability and expandability
It will be possible to deliver messages of the highest
priority to the correct address in less than 2 minutes.
The system will manage a significant number of incoming
and delivered messages per hour. The security, that
can be incorporated, will ensure that military messages
of highest classification can now be transferred automatically,
and therefore messages previously sent by courier may
be sent rapidly via IDCN - all traffic can be automatically
encrypted. Availability is ensured by fault-tolerant
equipment, dualization and components of the highest
reliability.

The IDCN network will consist of a number of nodal
switching centers, interconnected by dual internodal
trunk lines, operated at high speeds.
The nodal switching centers are configured with three
functional entities:
NODE - providing access to IDCN for data terminals,
interfacing MEDEs, and performing network-oriented
functions common to both data and message
traffic.
MEDE - Message Entry And Distribution Equipment,
providing access to IDCN for communications
centers and performing terminal-oriented
functions related to message traffic, similar
to CAMPS.
SCC - System Control Center, providing network
supervision and control, functions as a
center for software development and maintenance.
These IDCN system elements will be co-located and physically
integrated.
IDCN will be structured as a multi node grid network
whose topology is shown in figure 1.1 - 1.
