    when at least a decode threshold number of the FEC encoded words are retrieved;

    combining the at least a decode threshold number of the FEC encoded words to produce FEC encoded data; and

    FEC decoding the FEC encoded data to produce recaptured data;

    generating recaptured integrity information based on the recaptured data;
