Creating a test system for a new era of radios

Sammanfattning: As communication becomes more and more vital in defending a country’s borders, better radios are needed. When the Swedish armed forces saw that their existing radios took too much bandwidth in their net, they knew that something had to be done. The existing radio, called Ra 180 RAP, was modified so that it could send X.25 messages into a network. This significantly reduced the use of bandwidth, as a packet switched network only uses the bandwidth when sending info. This final thesis has been aimed to create a system that can test the X.25 function in the upgraded, so called CI-RAP, radio. This system will come in handy both when upgrading and later when performing service on the radios.
