ATM cell error processing system

An ATM cell error processing system includes a plurality of error detectors (30) for respectively detecting predetermined cell errors and for respectively generating decision signals, an error editing unit (31) which is operatively coupled to the error detector and determines, on the basis of the decision signals, whether or not a cell related to the decision signals should be discarded. A buffer (32), which is coupled to at least one of the error detector, temporarily stores the cell. An error cell discarding unit (33), which is coupled to the error editing unit and the buffer, discards the cell from the buffer when the error editing unit determines that the cell should be discarded and relays the cell when the error editing unit does not determine that the cell should be discarded.
