Patent ID: 7729384

Claim:
A multicarrier transceiver comprising: a digital signal processor; and a framer, the framer including: a scrambler coupled to the digital signal processor; and a Reed-Solomon encoder coupled to the digital signal processor configured to accept user and control data in one or more logical channels, partition the user and control data into one or more frames, wherein the frame boundaries are implicitly accounted for by processing the one or more logical channels independently; randomize the user and control data through the scrambler, and multiplex the one or more logical channels into a single data stream; a FIFO buffer configured to alter the user and control data in the one or more logical channels to enable processing on codeword boundaries to enable context changes between the one or more logical channels to occur independent of a saved context, the FIFO buffer configured to be shared by one or more interfaces that do not operate simultaneously and the FIFO buffer configured to receive user and control data from an interleaver or directly from the Reed-Solomon encoder as a function of a type of logical channel.
