An ATM technology testbed is currently under development within the European RACE 1022 project and is characterized by the separation of transport and control functions into a transport network and a control network respectively.After mentioning general concepts for an ATM target network architectural model,this paper focus on the control network outlining basic features for this network and for its control stations,and presenting the solution adopted within the R1022 testbed.The ATM Control Adapter which allow control stations to bc connected to this testbed is described in detail.Although some realizations of Intelligent Networks (IN) on existing networks are being carried out in several countries,more research is required for ineluding INs into ATM networks to support multimedia IN services.This paper explains how an advanced IN can be introduced in the future erdaanced R1022 testbed using multimedia control stations whose architecture is described.
