ABSTRACT:
In a communication system utilizing DMT technology to couple a primary site (102) to a plurality of secondary sites (104-108), infrastructure control channels are established in the following manner. Having obtained a plurality of site bit loading tables, the primary site (102) generates a control channel bit loading table from the plurality of site bit loading tables. From the control channel bit loading table, the primary site selects at least one carrier channel to function as the control channel. The selection is based on bandwidth requirements for the control channel.
