ABSTRACT:
A network node (10) for switching digital information of different protocol types is described. A plurality of modules (12-x,13-x,14-x) are provided which are arranged in an input stage (12), a central stage (13) and an output stage (14). Each module (12-x) of the input stage (12) is connected to each module (13-x) of the central stage (13) and each module (13-x) of the central stage (13) is connected to each module (14-x) of the output stage (14). A standard interface (15) for all protocol types is in each case provided between the input stage (12) and the central stage (13) and between the central stage (13) and the output stage (14). Each of the modules (13-x) of the central stage (13) is designed for one protocol type. The interfaces (15) comprise means for forwarding information as a function of the protocol type to a module (13-x) of the central stage (13) adapted thereto.
