Claim:
A method, comprising: determining, by a service provider system associated with a service provider and comprising one or more computers, respective linear impairment information for a plurality of customers of the service provider; assigning, by the service provider system based at least in part upon an analysis of the determined linear impairment information, each of the plurality of customers to one of a plurality of groups, wherein the customers assigned to each of the plurality of groups are associated with similar linear impairments; determining, by the service provider system, for each of the plurality of groups, a range of frequencies at which communications will be output by the service provider for receipt by the customers assigned to the respective group, the determination of the range of frequencies further comprising: determining, by the service provider system, for each of the plurality of groups, an approximate amount of linear impairment associated with the respective group; determining, by the service provider system, for a first group of the plurality of groups having a first approximate amount of linear impairment, a first range of frequencies based at least in part on the determined amount of linear impairment; and determining, by the service provider system, for a second group of the plurality of groups having a second approximate amount of linear impairment greater than the first approximate amount, a second range of frequencies based at least in part on the determined amount of linear impairment, wherein the second range of frequencies is lower than the first range of frequencies.
