1. An apparatus for interchange of user data and control data associated with the user data between a communications application and a communications installation which are connected via a packet-switched network, comprising:

  • an application-end primary control unit, which interchanges combined control data with the communications application, the primary control unit having first and second channels;

    a first transmission path to interchange basic control data and the user data, on the basis of a first transmission standard, between the primary control unit and the communications installation, the basic control data being transmitted using the first channel;

    a second transmission path based on a second transmission standard, to transmit extended control data to and from the communications installation;

    an auxiliary control unit to interchange extended control data with the communications installation via the second transmission path, to interchange basic control data with the first channel of the primary control unit, and to interchange combined control data with the second channel of the primary control unit; and

    a splitting-combining element provided in the auxiliary control unit to split combined control data into basic control data and extended control data and to form combined control data by combining basic control data and extended control data.
