Abstract
An example apparatus comprises a processor, and a memory element in communication with the processor. The processor configured to send a first message to at least a first cable modem of a plurality of cable modems. The first message indicates an upstream test signal to be generated by the first cable modem within a predetermined portion of a frequency spectrum allocated for downstream communication. The processor is further configured to send a second message to at least a second cable modem of the plurality of cable modems. The second message indicates a downstream interference measurement to be performed on the upstream test signal by the second cable modem. The processor is further configured to receive at least one interference measurement result indicative of the downstream interference measurement, and determine at least one interference group for the plurality of cable modems based upon the at least one interference measurement result.
