Abstract
A multi-tone modem supporting multi-tone modulation protocols over multiple bundled transmission lines. The multi-tone modem is configured to transmit and receive communication channels each associated with a corresponding one of a plurality of transmission lines. The modem comprises at least one in-channel forward error correction component and a cross-channel forward error correction component. The at least one in-channel forward error correction component discretely encodes and decodes data from each communication channels transmitted and received over the plurality of transmission lines. The cross-channel forward error correction component encodes data from all communication channels and buffers the corresponding cross-channel redundancy symbols of each cross-channel codeword.
