The Norwegian-Swedish ISI project (Inter System Interface) is a development scheme between Norway and Sweden. The purpose is to facilitate cross-border command and collaboration through creating possibilities for stakeholders in both these countries to utilise their own equipment within the framework of Nødnett (Norwegian Public Safety Network) and Rakel (Swedish Emergency Communication Network). The project is carried out during the period 2013-2016 and involves Norwegian and Swedish representatives from the ambulance service, the rescue service, the police and health/amulance service. The responsible authorities are the Swedish Civil Contingencies Agency (MSB) in Sweden and the Directorate for Emergency Communication (DNK) in Norway.
