Apparatus and method for data interchange
First Claim
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.

Abstract
Data are interchanged between a communications application and a communications installation via an IP network. To this end, the communications application uses an application-end primary control unit to communicate with the communications installation. A first transmission path is used 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, and a second transmission path based on a second transmission standard is used to interchange extended control data between an auxiliary control unit and the communications installation. For transmission in the direction from the communications installation to the communications application, the basic control data are first transferred from the primary control unit to the auxiliary control unit, are combined with the extended control data by the auxiliary control unit, and are then transmitted as combined control data from the auxiliary control unit to the primary control unit for forwarding to the communications application, and vice versa.

13. A method for interchanging 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:
-
interchanging basic control data and the user data on the basis of a first transmission standard between a primary control unit and the communications installation, the basic control data and the user data being interchanged via a first transmission path;
interchanging extended control data between an auxiliary control unit and the communications installation, the extended control data being interchanged via a second transmission path and a second communications standard;
upon transmission from the communications installation to the communications application;
passing the basic control data from the communications installation to the primary control unit via the first transmission path, transferring the basic control data from the primary control unit to the auxiliary control unit, combining the basic control data with the extended control data in the auxiliary control unit to thus form combined control data, transferring the combined control data from the auxiliary control unit to the second control data channel of the primary control unit, and forwarding the combined control data from the primary control unit to the communications application; and
upon transmission from the communications application to the communications installation;
passing combined control data from the communications application to the primary control unit, forwarding the combined control data from the primary control unit to the auxiliary control unit using the second control data channel of the primary control unit, splitting the combined control data into basic control data and extended control data in the auxiliary control unit, transmitting the basic control data to the first control data channel of the primary control unit, forwarding the basic control data to the communications installation via the first transmission path, and forwarding the extended control data via the second transmission path.
