ABSTRACT:
In an asynchronous transfer mode (ATM) system, interleaved cells are formed at the transmit end by combining into each interleaved cell certain bits from each of plural different original ATM cells, the interleaved cells are transmitted over the communications link, and then deinterleaved at the receive end. Any bursty errors occurring on the communications link will, after deinterleaving, be spread out over multiple original ATM cells, maximizing the error correction for ATM cells and error detection for AAL capability and minimizing loss of data. The C1 byte in the Physical Layer Convergence Protocol (PLCP), which indicates the location of end of the PLCP frame, is protected against the burst errors by replication of C1 byte through inserting them in the growth bytes Z1 through Z4.
