Abstract
A gateway (MG1) interconnects telecom networks (N1,N2) of different types with different signal formats (ATM,IP). A first control unit (CC1), connected (C1) to a server, controls connection set up. A second control unit (RC2) provides telecom functions (F21-F28), such as speech coder/decoder or echo extinguisher, to the connection. A third control unit (BC3) establishes connections and sets up switch functions (CP21-CP27) corresponding to the different signal formats (ATM,IP). A signal format converter (CP29) converts to/from a common signal format (COM1) that the telecom functions uses. A speech request goes via the server to the first control unit (CC1), which requests telecom function (F21) by the second control unit (RC2). This returns the address (ADR11) of the telecom function to the first control unit (CC1) which sends the function address (ADR11) and the network address (ADR2) of the connection to the third control unit (BC3). This interconnects the corresponding switch function (CP23) and the telecom function (F21) after conversion to the common signal format (COM1) in the signal format converter (CP29). The first control unit (CC1) thereafter requests connection to the ne…
