    摘要: The invention concerns an ATM exchange, and is directed in particular to the provision of a cell bandwidth control apparatus for performing bandwidth control for ATM cells sent from the ATM exchange onto the line side. The cell bandwidth control apparatus includes forced empty cell inserting means for forcibly inserting empty cells in a highway connected to an ATM switch. The forced empty cell inserting means inserts forced empty cells in an outgoing highway leading from the ATM switch to a line adapter and thereby limits the line bandwidth of the outgoing highway to within the bandwidth of the line accommodated in the line adapter.

    摘要: A plurality of input lines are respectively connected to separate multiplexing units that are connected in cascade by cascading lines. Select signals are transferred in parallel with fixed length packets over the cascading lines. Each separate multiplexing unit is responsive to a select signal received from the cascading line to select one of fixed length packets received over the corresponding input line and the upstream cascading line and output it over the downstream cascading line. The most downstream separate multiplexing unit provides a multiplexed output of the input lines.

    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: A device for discriminating timeout comprises an event discrimination unit, a calculation unit, a timing storage unit and a timeout discrimination unit. The event discrimination unit outputs each communication information concerning each communication to the calculation unit, when an event indicating a start of timeout discrimination occurred. The calculation unit calculates a timeout timing for every communication on the basis of the each communication information and the timing in which the event has occurred, and writes the calculated timeout timing into the timing storage unit. The timeout discrimination unit compares the timeout timing read out from the timing storage unit for every communication with the present timing, and discriminates that the timeout has occurred in reference to the communication when the present timing exceeds the timeout timing.
