ABSTRACT:
A program controlled data processor particularly useful in data transmission systems is described. In this system the central processing units communicate with central storage units, which receive all data and programs for carrying out switching functions. In order to increase the operational reliability at least two identically constructed storage units and/or at least two identically constructed processing units can be connected to operate in parallel performing the same functions concurrently and synchronously. The bits of information supplied by the parallel system units are compared and in case of malfunction or disturbance the transfer of information is inhibited. Comparator circuits are provided which can be selectively connected to any of the system units which are to be connected in parallel.
