System Requirements Specification
1. I̲N̲T̲R̲O̲D̲U̲C̲T̲I̲O̲N̲
In 1973, the Military Committe approved a concept for
the improvement of command and control through the
use of ADP. This concept includes a requirement for
the interlinking of host computers supporting an ACE
wide data base which is updated from information primarily
contained in original messages of the ACE reporting
system. The interlinking of CAMPS, SCARS and ACE CCIS
systems is a major step towards the realization of
this concept. The CAMPS (Computer Aided Message Processing
System) will be installed at SHAPE and in the Central
Region (CR) starting in January 1983. As of Jan 1983,
testing will begin and continue until June 1983 Likewise,
sCARS II (Status Control Alerting and Reporting System)
will be installed at SHAPE starting in June 1983.
CAMPS and SCARS II are required to interface with the
Honeywell 6060 at SHAPE and the Central Region (CR)
to permit an automated message flow between the networks
supporting the systems. Interface adaptions are required
at SHAPE and in Central Region Sites supported by existing
CCIS Honeywell 6060 equipments.

3.4.7.4 F̲a̲l̲l̲b̲a̲c̲k̲ ̲p̲r̲o̲c̲e̲d̲u̲r̲e̲s̲
The converter is not required to provide a fallback
capability for the computer systems. When a link with
it is broken, the converter will reflect that state
to the other end of the link.
3.4.7.5 I̲n̲f̲o̲r̲m̲a̲t̲i̲o̲n̲ ̲e̲x̲c̲h̲a̲n̲g̲e̲ ̲p̲r̲o̲t̲o̲c̲o̲l̲ ̲a̲n̲d̲ ̲p̲r̲o̲c̲e̲d̲u̲r̲e̲s̲
a) The converter shall match the different data exchange
protocols implemented in the CAMPS, SCARS and CCIS
systems.
b) The link between CAMPS/SCARS and the converter
shall operate in accordance with the SS document.
c) The converter - CCIS link shall operate with Honeywell
WWMCCS RCI and DINDAC protocols.
d) The converter shall act as a "transparent box"
when there are no protocol/transaction errors.
e) When protocol/transaction errors occur, the converter
will detect the errors and react through the defined
protocol capabilities.
f) A protocol/transaction error is in this respect
defined as a recoverable:
- inconsistency in the level 2 or 3 header of
the CAMPS/SCARS protocol
- inconsistency in the RCI protocol or DINDAC
segment header for the WWMCCS protocol.
g) Unrecoverable protocol/transaction errors can by
definition not be corrected in the converter. These
errors shall be trapped in the converter and the
two interconnected systems notified through the
defined protocol facilities.
h) CR shall as part of the design documentation specify
the protocol/transaction error conditions that
can occur and the actions to be taken by the converter,
the CCIS and the CAMPS/SCARS II system.
3.4.7.6 S̲e̲r̲v̲i̲c̲e̲ ̲M̲e̲s̲s̲a̲g̲e̲s̲ ̲b̲e̲t̲w̲e̲e̲n̲ ̲C̲A̲M̲P̲S̲/̲S̲C̲A̲R̲S̲ ̲-̲ ̲C̲C̲I̲S̲
Service Messages between the interconnected systems
will be passed through the converter transparently
like messages. No special actions shall be taken by
the converter.
3.4.7.7 S̲e̲r̲v̲i̲c̲e̲ ̲M̲e̲s̲s̲a̲g̲e̲s̲ ̲t̲o̲ ̲t̲h̲e̲ ̲c̲o̲n̲v̲e̲r̲t̲e̲r̲
Service messages between a system and the converter
shall be exchanged in accordance with the respective
exchange protocols and procedures on the two links
of the converter.
The service messages are:
- log-on to WWMCCS
- log-off to WWMCCS.

a) To perform all work necessary and pay all
associated costs to make the site ready
for installation of contractor's equipment
according to contractor's Site Civil Work
Drawings as modified by SHAPE or the territorial
host nation, if appropriate, to meet territorial
host nation laws and regulations.
b) Customer will remain responsible for all
site preparation until site has been verified

staff and/or supplies are denied access
to the site, a claim will be submitted
by contractor. This claim will be resolved
under Clause 37 of SHAPE's General Provisions
"SHAPE Delay of Work".
d) Customer shall notify contractor of a site's
readiness at the same time as the relevant
