    摘要: An optical space switch is formed in such a manner that switch elements having two inputs and two outputs are arranged in an n.times.n matrix form and optical signals from n input highways are switched to n output highways. The switch elements are connected in such a manner that the optical signals are always passed through the same number of switch elements, from the input highways to the output highways.

    摘要: The object of the present invention is accomodating local connectionless information (data that is immediately transferred without establishing a path to a receive side), such as LAN data in a local area network, by an asynchronous transfer mode (ATM) network using a connection-oriented communication system (which makes data transfers after verifying that a path to the receive side has been established), thereby performing efficient, fast routing of connectionless information. A connectionless communication system of the present invention is equipped with connectionless information cell assembly/deassembly means for bi-directional conversion between variable-length connectionless information and fixed-length connectionless cells, routing control means for analyzing a destination address of information in connectionless cells and controlling the routing of the connectionless cells; and an ATM network for connecting the connectionless information cell assembly/deassembly means and the routing control means by a permanent virtual channel serving as a fixed path and connecting the routing control means together by a virtual channel serving as a semi-fixed path, whereby connectionless information is segmented into connectionless cells and the connectionless information is exchanged within the ATM network in connectionless cell units.

    摘要: An Asynchronous Transfer Mode (ATM) cell error processing system includes a plurality of error detectors for respectively detecting predetermined cell errors and for respectively generating decision signals and an error editing unit which is operatively coupled to the error detector and determines, based on the decision signals, whether or not a cell related to the decision signals should be discarded. A buffer, which is coupled to at least one of the error detectors, temporarily stores the cell. An error cell discarding unit, which is coupled to the error editing unit and the buffer, discards the cell from the buffer when the error editing unit determines that the cell should be discarded and relays the cell when the error editing unit determines that the cell should not be discarded.

    摘要: A switch includes a plurality of memories respectively having write terminals connected to input ports and output terminals, each of the memories including an input acknowledgement signal generating block for generating an input acknowledgement signal when data is received thereto. A multiplexer, which is coupled between the read terminals of the memories and an output port, connects one of the memories to the output port in response to a port number signal. An output controller, which is coupled to the memories and the multiplexer, receives the input acknowledgement signal from each of the memories in order of receipt and generating the port number signal so that data stored in the memories is selected by the multiplexer in order of receipt of the input acknowledgement signal.
