Abstract
In a communication system that utilizes DMT technology to couple a primary site (102) to a plurality of secondary sites (104-108), carrier channel allocations may be updated as follows. At periodic intervals, the primary site requests updating bit loading information from the secondary sites. Upon receiving the updated bit loading information, the primary site (102) determines an updated call bit loading table for each active call. From this, the primary site (102) determines whether current carrier channel allocation provides sufficient bandwidth. When the current carrier channel allocation does not provide the sufficient bandwidth, the primary site modifies the current carrier channel allocation to meet the bandwidth requirements.
