E. TACTICAL CCIS - TOSCA
I̲I̲I̲ ̲ ̲T̲O̲S̲C̲A̲
1. O̲B̲J̲E̲C̲T̲I̲V̲E̲
The TOSCA System was initially delivered to the Royal
Danish Air Force in 1972 with the objective of providing
the airforce with fast status reporting from several
national centers and fast communication and display
facilities for summary logistics displays and free
text messages and commands.
2. B̲E̲N̲E̲F̲I̲T̲S̲
The TOSCA System is a limited CCIS type system. It
provides the Danish Airforce with facilities for collecting
status information on national resources, and displaying
this information on the Danish Control and Reporting
sites for subsequent consolidation with NATO Air Defense
Ground Environmental data (NADGE).
The main features of the TOSCA system are:
- to c̲o̲l̲l̲e̲c̲t̲ information from various reporting sites
where the information is entered at local VDUs
or from magnetic tape equipment
- to s̲t̲o̲r̲e̲ this information at a number of selected
main sites
- to c̲o̲n̲t̲r̲o̲l̲ ̲a̲n̲d̲ ̲d̲i̲s̲t̲r̲i̲b̲u̲t̲e̲ the data-traffic between
the sites internally and between the sites and
the computer installations
- to d̲i̲s̲p̲l̲a̲y̲ the selected information at the individual
sites on video monitors,
- to s̲e̲c̲u̲r̲e̲ all information by the use of encrypted
data traffic.
Information reporting and display uses an operator-friendly
man-machine interface. All inputs are made on VDU's
through a format mask with protected and unprotected
field facilities and syntax checking.
3. S̲Y̲S̲T̲E̲M̲ ̲D̲E̲S̲C̲R̲I̲P̲T̲I̲O̲N̲
The system was initially developed in 1972 and is based
on communication technology of that time. A generic
diagram of the system is shown in figure 1.
The system consists of a number of main sites interlinked
with two multidrop leased telephone lines. The equipment
at the main sites consist of computer facilities, VDUs
for update of information and test masks, and monitors
and printers for presentation of the information.
Each site is linked to several airbases and reporting
centers with multidrop leased telephone lines. Each
of these sites can be equipped with alfanumeric VUDs,
video monitors and printers.
The system has reasonly been upgrated to include encryption
on all data lines through use of DOLCE equipment.
4. E̲q̲u̲i̲p̲m̲e̲n̲t̲ ̲a̲n̲d̲ ̲E̲x̲p̲a̲n̲d̲a̲b̲i̲l̲i̲t̲y̲
The installed system is based on 1972 technology. The
original modular design of both hardware and software
provides an excellent background for adapting the system
to modern computer and communication technology.
The rapid development within computer technology will
facilitate many improvements, such as:
- redundant communication facilities
- extended storage facilities
- improved man-machine interfaces with highly intelligent
VDUs
- improved status display facilities
- improved security.
