Abstract
An improved method of forward error correction in a data communications system that includes receiving a data frame that includes a filler symbol, detecting an error in the data frame, replacing the filler symbol with a predetermined symbol, and determining when the error has been corrected. Detecting the error includes performing a first parity check, preferably a CRC computation that is repeated a second time, after replacing the filler symbol, to determine when the error has been corrected. When replacing the filler symbol(s) has corrected the error, an automatic retry request may be foregone thus conserving channel capacity.
