Abstract
A plurality of cable modems (CMs) serviced by a cable management termination system (CMTS) are identified, each of the CMs being associated with a particular bandwidth service tier of a plurality of bandwidth service tiers. The plurality of CMs are grouped into a quantity of groups of CMs based on the bandwidth service tier with which each CM is associated. A CM orthogonal frequency division multiplexing (OFDM) profile is generated for each respective CM in each group of CMs. A plurality of group OFDM profiles are generated. Each respective group OFDM profile is generated based on the CM OFDM profiles of the CMs in a respective group of CMs and, for each subcarrier of a plurality of subcarriers, a quadrature amplitude modulation (QAM) order is identified.
