ABSTRACT:
A switching network for the pick-up and forwarding of data streams has a plurality of input line units and output line units which respectively accept or output data streams in fixed multiplex frames, and which are connected in common to an exchange bus. A respective data memory whose memory cells are individually allocated to the bit places of a multiplex frame for the individual output line units is provided in the input line units. The data bits of a multiplex frame are entered bit-by-bit into the corresponding memory cells in the data memories based on the criterion of allocation information. The memory cells of the individual data memories are synchronously driven by a central control unit in a fixed sequence for the output of stored data bits onto the exchange bus. Only one of the data bits corresponding to one another in the individual data memories is thereby enabled based on the criterion of enable information, whereas the others are masked. The output line units are driven in a corresponding sequence for the acceptance of valid data bits.
