Efficient implementation of X.25 on narrowband packet radio systems

In order to maintain the maximum flexibility in the deployment of components of CIS (command, control and intelligence) systems and to simplify the design, implementation and deployment of the gateways, a common network interface is required. With the NATO policy of applying ISO based protocols (with military enhancements) wherever possible, this suggests the X.25 series of protocols for the bottom three layers of the OSI model. The author describes a combination of communications protocols with signal processing techniques designed to provide data communications in the far forward tactical environment by applying packet switching techniques to conventional combat net radio
