Abstract:
A cell fluctuation absorption receiving system, comprising:a data communication apparatus; an ATM switching network; a cell assembly and disassembly device coupling said data communication apparatus and said ATM switching network; a plurality of input-output interfaces connected to said data communication apparatus; a data highway connected to one of said input-output interfaces for transfer of cell data in frames, each frame having a fixed number of time slots and having a fixed time length; a receiving buffer connected to said data highway for storing time slot data for a plurality of frames; means to store time slot data for a number of frames as dummy data in said receiving buffer before storing first received cell data in said receiving buffer, with said number of frames providing a fluctuation guarantee time; and receiving data storing means for storing said first received cell data in said receiving buffer in an area behind an area in which said dummy data is stored, wherein said cell assembly and disassembly device assembles data made up of a bit string received from said data communication apparatus into cells and disassembles cells received from said ATM switching network into data made up of a bit string each of the assembled and disassembled bit strings having a fixed communication speed.
