Claim Text:
1. A method, comprising: creating a plurality of profiles that describe one or more downstream modulations for each data-subcarrier in a channel to be used by a plurality of cable modems, wherein each of the profiles includes a list of modulation orders for one or more subcarriers within an orthogonal frequency-division multiplexing (OFDM) channel, wherein the plurality of profiles are associated with the OFDM channel for a downstream path between a cable modem termination system (CMTS) and the plurality of cable modems; receiving at least one testing measurement from the plurality of cable modems; and assigning a selected one of the plurality of profiles to each of the plurality of cable modems based, at least in part, on the one testing measurement that was received.
