Claim:
1. A method for channel scanning comprising: receiving a downstream network signal; identifying a first wideband frequency block in the network signal; identifying a number of demodulators available in a communications device; identifying a plurality of subfrequencies within the first wideband frequency block, wherein the plurality of subfrequencies identified matches a number of available demodulators; for each respective one subfrequency of the identified plurality of subfrequencies, attempting to lock onto the respective one subfrequency with a respective one demodulator of the available demodulators, wherein the individual processes of attempting to lock onto each of the identified plurality of subfrequencies occur in parallel to each other; identifying a first subfrequency from the identified plurality of subfrequencies on which one of the number of demodulators has achieved lock; and performing ranging and registration for the first subfrequency if demodulator lock has been achieved for the first subfrequency by one or more of the demodulators.
