  • Variable rate digital switching system
    Patent number: 6683872
    Abstract: There is provided a variable rate digital switching system comprising steps of: arranging a plurality of incoming TDM buses and a plurality of sending TDM buses in lattice form; providing cross-point buffers at cross-points of the incoming buses and the sending buses; connecting the cross-point buffers belonging to respective sending TDM buses to respective scheduler; connecting respective contents analyzer to respective scheduler; checking frame headers of input TDM frames by respective cross-point buffers, thereby buffering only data of time slot of destined and belonged sending bus and transmitting contents of the frame header to the contents analyzer; checking the frame header by the contents analyzer, thereby deciding the contents of data stored in the respective cross-point buffers on the own-belonged sending TDM bus, and informing them to the scheduler; performing the scheduling by the scheduler as for how time slots in the sending TDM frame is allocated in respective cross-point buffers according to t

  • Variable rate TDM switching system
    Patent number: 6628650
    Abstract: There is provided a variable rate TDM switching system comprising steps of: arranging a plurality of incoming lines and a plurality of sending lines in lattice form; providing time-division gates at cross-points of the incoming lines and the sending lines; connecting time-division temporal switches having a function of transposing the order of time slots in input TDM frames to forward stage of respective incoming lines of the time-division space switches for performing the switching between the incoming lines and the sending lines with time slot unit while holding the multiplexing, by switching these time-division gates; connecting a scheduler for concentratedly controlling the time-division gates and the time-division temporal switches to these gates and time switches; transmitting the headers of the TDM frames to the scheduler in case of inputting the header of TDM frame, and deciding the temporal switching schedule by the scheduler as to the transposition of the order of time slots in the time-division tem
