A method and apparatus is disclosed that allows data communication within a packet based communication system by incorporating information within the physical link layer. Information is communicated from a transmitter to a receiver within the physical link layer by substituting idle data fields with input data fields. The transmitter comprises a data insertion multiplexer to generate and insert physical link layer data, and the receiver comprises a data extraction de-multiplexer to detect and extract the physical link layer data.
