Abstract
A system for transmitting information data packets over a network includes a plurality of parallel transmission channels, each receiving interleaved data words constituting the data packets. Each channel includes a corresponding check sum data generator to compute check sum data for a corresponding sequence of data words. A logic circuit responsive to the interleaved data words from each channel performs an arithmetic operation on the data words from those channels to generate a parity data stream onto a separate channel. A check sum data generator computes checksum data based on the parity data stream. An encoder device downstream from each checksum data generator encodes the data and checksum from each channel for serial transmission over a network.
