		At the initialization, the receiver’s error correction algorithm is in the default mode for  single-bit error correction. As each cell is receive, the HEC calculation and comparison is performed. As long as no errors are detected, the receiver remains in error correction mode. When an error is detected, the receiver will correct the error if it is a single bit error or will detect that multiple error has occurred. In either case, the receiver now moves to detection mode.  The receiver remains in detection mode as long as errored cells are received. When a header is examined and found not to be in error, the  receiver switches back to correction modes.
