PURPOSE: A duplexing apparatus is provided to minimize cell delay by using a header error control in an asynchronous transfer mode(ATM) system. CONSTITUTION: A duplexing apparatus in an asynchronous transfer mode(ATM) system comprises an ATM cell transmitter(30) and an ATM cell receiver(40). The ATM cell transmitter duplexes cell receivers(414,424) and header error control generators(412,422). Each of the header error control generators executes a header error control operation for header information of ATM cells, received via the cell receivers. Each of the header error control generators inserts an operated result to headers of the ATM cells by adding one byte to the operated result, and transmits the operated result. The ATM cell receiver comprises cell receivers(314,324), header error control examiners(312,322), and a cell selector(430). The cell receivers receives the ATM cells from the ATM cell transmitter. Each of the header error control examiners executes an error examination through a header error control operation for the headers of the ATM cells, supplied via the cell receivers. The cell receivers and the header error control examiners are duplexed. The cell selector selectively outputs each of the ATM cells output from the header error control examiners by an error-examining result.
