Abstract
A method and a circuit arrangement are provided for the transmission of communication signals over switching centers of a first switching network and of a second switching network operating with different transmission procedures. The transmission is executed with the assistance of a decentralized converter in which a fixed assignment between the transmission lines of the first switching network and the virtual channels to be employed on transmission lines of the second switching center for a signal transmission is defined. Of the signals to be transmitted, only the signal portions effecting the execution of network-dependent procedure divisions are converted in the converter. The data signals appearing in accordance with the network-independent procedure divisions are combined in unaltered form with the converted signal portions.
