The invention relates to a communications system and a method for establishing a broadband connection, for example a multi-media connection between two or more users (A-Tln, B-Tln), by means of exchanges in a communications network, for example an ATM network. According to the invention, when the exchanges receive a request from a calling user (A-Tln) to establish a broadband connection, said exchanges first establish a minimal connection between the users (A-Tln, B-Tln) and once the minimal connection is in operation between the users (A-Tln, B-Tln), the requested broadband connection is established. The users (A-Tln, B-Tln) of broadband network capacities, which have been reserved by the network at the request of the user (A-Tln), are billed during the call phase. Broadband connections of this type can receive a higher priority than the upgrade of minimal connections to complete connections. A voice connection comprising audio data constitutes for example a minimal connection. The broadband connection takes place for example between video telephones.
