Abstract

In a communication system that utilizes DMT technology to couple a primary site (102) to a plurality of secondary sites (104-108), the primary site (102) and each of the secondary sites (104-108) includes a DMT transmitter. Such a DMT transmitter includes a discrete multi-tone encoder that receives an ordered data stream and produces an encoded data stream based on bit loading information, and a data formatter operably coupled to the discrete multi-tone encoder, wherein the data formatter receives transmit data entries and produces the ordered data stream based on carrier channel allocation information.
