ABSTRACT:
In a communication system that employs DMT technology to couple a primary site (102) to a plurality of secondary sites (104-108), call support infrastructure is obtained as follows. Having received a call request, the primary site (102) identifies targeted subscribers and target secondary sites, i.e., the secondary sites having a targeted subscriber affiliated therewith. Next, the primary site determines a call bit loading table from the site bit loading tables of the target secondary sites. Having done this, the primary site selects, based on bandwidth requirements of the call, at least one carrier channel to provide the infrastructure support for the call.
