Abstract
Disclosed are a method apparatus for performing periodic ranging with a cable modem. It is determined whether an actual power level of the cable modem requires adjustment to a desired power level and it is indicated to the cable modem that it should adjust the actual power level to an adjusted power level that differs from the actual power level of the cable modem by less than or equal to a first dynamic range associated with the cable modem. In one extension of this method, the first dynamic range represents a difference between a modem dynamic range of the actual power level output by the cable modem and a head end dynamic range for recognizing the actual power level output by the cable modem.
