PURPOSE: A cell/packet switching system configured with planes is provided to configure multiple planes, to compensate an additional time block for bit and word synchronization for output data of an asynchronous cross pointer/cross bar switch for sequential activation and operation. CONSTITUTION: Input/output buffering units(4100,4200,4300) stores cell/packet inputted at a high speed, for waiting. Cross pointer/cross bar switching units(4410,4420,4430) are configured with multiple planes, for interfacing and switching with the input/output buffering units(4100,4200,4300) through a high speed serial bit stream input/output. A cell/packet arbitrating unit(4500) performs arbitration for the output control of the cell/packet stored in the input/output buffering units(4100,4200,4300), outputs shape change information to the cross pointer/cross bar switching units(4410,4420,4430), and sequentially activates the cross pointer/cross bar switching units(4410,4420,4430) to output the shape change information.
