Two subscribers A and B are each connected to a network, e.g. by means of a leased line or a dialup connection. Subscriber A sets up a telephone connection to subscriber B. In the course of the telephone connection, a data connection additionally needs to be set up. A service provided by the telephone network operator and an appropriate method taking place on the subscribers data terminal equipment automatically transfer the data network addresses of the subscribers involved in a connection and also the connection configuration of the telephone connection to the subscribers data terminal equipment. This means that a data network connection can automatically be set up for a telephone connection on request.
