A system architecture offering services comprises a Connection Management, a Service Management, and a Communication Session Management CSM. A special adaptation software forms a description of the logical configuration of the communication between the parties of the service, and a description of the status of the connection organs, which describes the physical connection between the subscribers or subscriber and a legacy exchange. In response to the system service request by the telecommunication network, the Service Management gives a description of the desired communication status which corresponds to the requested service of the communication status, and the description of the state of the connection organs. The Communication Session Management CSM determines what kind of communication status corresponds to the given connection status, utilizing the description of the status of the connection organs that has been transmitted to it. In response to the connection status, the Connection Management makes the connections in such a way that a connection corresponding to the desired service will be created.
