Abstract

A media independent interface and circuitry of a forward error correction (FEC) sublayer are provided, the circuitry of the FEC sublayer to perform forward error correction, the FEC sublayer coupled to a physical coding sublayer and a physical medium attachment (PMA) sublayer. The FEC sublayer include an encoder having a reverse gearbox, a compressor coupled to said reverse gearbox, a selector coupled to said compressor, a parity generator coupled to said compressor, a multiplexer coupled to said compressor, selector and said parity generator, a scrambler coupled to said multiplexer, and a pseudo-noise generator coupled to said scrambler.

First claim

The invention claimed is:

1. An apparatus, comprising:
a media independent interface; and
circuitry of a forward error correction (FEC) sublayer to perform forward error correction, the FEC sublayer coupled to a physical coding sublayer and a physical medium attachment (PMA) sublayer, the FEC sublayer comprising an encoder having:
a reverse gearbox;
a compressor coupled to said reverse gearbox;
a selector coupled to said compressor;
a parity generator coupled to said compressor;
a multiplexer coupled to said compressor, selector and said parity generator;
a scrambler coupled to said multiplexer; and
a pseudo-noise generator coupled to said scrambler.
