Abstract
Binary data is transmitted to a network physical layer from a media access controller as a series of multibit nibbles and is encoded into a multi-level data stream and split among a number of transmission channels, thereby reducing the signal frequency necessary to carry the data on each one of the transmission channels. The multi-level signal is then translated at a receiver back into a binary data stream. In a specific embodiment, the symbol transmission frequency on each of the transmission channels is at the same frequency as the nibble transfer rate between the media access controller and the physical layer.
