Abstract:
An apparatus for protecting an asynchronous transfer mode (ATM) header from burst error comprising:an ATM exchanger for generating an ATM cell; an encoder for dividing said ATM cell into an ATM header and a ATM payload by deframing and reverse-multiplexing said ATM cell and for encoding an overhead bit of said ATM header by using a reed-solomon (RS) error correction code without changing the structure of an ATM cell for multiplexing said ATM header by applying said ATM header into a header error correction bit; a modulator for framing said ATM header and said ATM payload which are inputted from said encoder according to physical layer convergence protocol and for modulating said ATM header and said ATM payload; a demodulator for demodulating modulated data of said a modulator; and a decoder for dividing said ATM cell into said ATM header and said ATM payload by reverse-multiplexing said ATM cell by deframing the demodulated data of the demodulator according to the physical layer convergence protocol, and for decoding and correcting the burst error generated in said ATM header in order to multiplex and transmit the ATM header to said ATM exchanger.
