ABSTRACT:
An element for conveying cells which are received on input lines (7a to d) and are destined for an output line 10. The interconnection element includes comparators (9a to d), each coupled to an input line and checking whether path identifications contained in the cells are assigned to the output line. In addition, a multiplexer arrangement (18) is present which by coupling the input lines to buffers (20a to d), uniformly distributes cells arriving during a time frame and destined for the output lines over the buffers in accordance with a predetermined sequence. The system further includes a multiplexer (21) for cyclic reading of the cells from the buffer.
