Abstract: A system for a digital subscriber line (DSL) network with a DSL interface can operate with processing circuitry that can generate symbols in multicarrier communications with codewords for modulation of a parity check.

The processing circuitry reduces a number of parity bits by puncturing and a number of data bits for shortening of the codewords so that a codeword boundary is aligned with a symbol boundary for one or more symbols, or a transmission frame of symbols.
