Symicron Computer Communications Ltd, the UK's leading independent
manufacturer of ISDN systems, has provided the advanced technology to
enable the Ministry of Defence to save thousands of pounds by
transmitting secure encrypted data, at high speed, between military
units and platform integrators, over public ISDN Primary Rate networks
instead of over expensive private leased lines.

Symicron is working with the Public Private Partnership that is
developing the LION secure information transfer system and
interoperability network between units from all three services that may
be using different communications platforms. The other partners in this
project, worth approximately £3million, are the MOD, Aerosystems
International (prime contractor) and Zaxus, who are part of Racal
Electronics. Symicron are providing the end-to-end WAN communications
over ISDN that will enable the Lincoln based Sentry aircraft platform
rig to communicate directly with those for Sea King AEW helicopters,
Type 42 frigates, Sea Harrier and Tornado F3 aircraft in different
locations. Any additional locations can easily be added to the network
whenever required.

Symicron have provided ISDN Primary Rate Interfaces in PC-based
communications controllers and Basic Rate terminal adapters at the
remote sites that collect all the encrypted streams and send them, via
secure dial up connections over the public network, to a central site.
Symicron are also configuring and controlling the network using Zaxus IP
encrypters as well as installing and maintaining all the network hubs
and BT services.

According to Martin Wilson at Aerosystems International, "Because of the
new technology available from Symicron and Zaxus, this new system is
costing only about an eighth of what it would cost using traditional
leased lines to carry the IP traffic. The system is completely
automatic, transparent and self-managing. So far, two sites are up and
running and we expect the full system to be installed by the third
quarter of 2001. Symicron have responded magnificently to resolve any
small problems that have occurred and we have now got completely stable

John Tilbrook, Chairman of Symicron, commented, "The combination of
Symicron's communications and Zaxus' encryption technology has saved the
MOD a fortune for this specific solution. It would also be ideal for any
other government departments requiring fully encrypted SoHo operation."
