ABSTRACT:
A method and apparatus for connecting networks of different types of transmission wherein, in a first network, the data are transmitted in a circuit-switched manner, and in a second network, the data are packet switched and transmitted connectionlessly on the lower three protocol levels. To be able to perform the signaling in a simple manner, signaling units are used which process signaling messages of the circuit-switched network.
