Abstract
A data cell for transmission in asynchronous transfer mode through a switching network of a switching center includes a header containing routing and connection information. This routing and connection information is converted by reducing the number of bits to a neutral connection number and a logical output number at an input peripheral side of the switching network. Multiplexing equipment converts the logical output number into one of many possible route informations for routing along different paths to the same output so that the slices of the data cell are switched along different paths in the switching network. At the output side of the switching network is a demultiplexer for restoring the cell sequence which may have been lost during switching. Output peripheral equipment returns the routing and connection information in the header portion of the data cell to the original number of bits.
