    摘要： An asynchronous time division (ATD) switch for carrying out packet switching. In one embodiment a switch has 256 ports running at 155 M bits and is capable of switching incoming data cells at each of the input ports to any one of 256 output ports. At each input port a switch sequentially distributes the received data cells over 16 outputs each of which is connected to a different DMR circuit. There are 256 DMR circuits each having 16 inputs and 16 outputs. A DMR circuit is a fixed space switching device which has N inputs, N time intervals and N outputs and operates cyclically so that each input goes to each output for 1/Nth of the time. The inner stage of the ATD switch comprises 256 central switches each having 16 inputs and 16 outputs. Each central stage switch has its 16 inputs connected to 16 different DMR circuits. The fourth stage of the switch consists of another array of 256 output DMR circuits with each central switch being connected to 16 different output DMR circuits. Each input DMR has its outputs connected to 16 different output ports. The internal circuitry of the ATD switch runs on 20 M bits. When a data cell is received at an input port its destination is derived from a header attached to the cell. Control circuitry enables the receiving port to request three addresses to query three possible routes through the switch. The ability to provide this series of questions is given by staggering the windows through which an output port can communicate with the central switches. Although data streams are received asynchronously the operation of the ATD switch is synchronous.

    摘要： An ATM telecommunications switch includes a plurality of parallel data switching planes and a parallel control plane, each plane having an equal number of input ports and output ports and a central switching unit to switch each input port to any output port. A single data stream is divided between a plurality of input ports and the data is concatenated from a plurality of output ports to reconstitute the data stream. A first rotator connects each input port cyclically to each timelslot of the central switching unit and a second rotator connects each timeslot of the central switching unit cyclically to each output port.

    摘要： A wideband/multislot switching arrangement is provided for use in a digital telecommunications exchange. A call handling device is provided which receives signalling information about a path connection, and which communicates with a switch interface to generate a single switch request. The switch interface includes a map record of each circuit connection controlled by the call handling device and generates multiple switch requests which are used to control a number of switches to make the path connections.
