In a data communications system including an infrastructure and a subscriber unit operating with a protocol that mandates proactive scanning, a method of power conservation practiced at the subscriber unit including monitoring a registered data channel during an active time period (403), assessing the data channel during the active time period to provide a channel quality value (407), comparing the channel quality to a first threshold (413), assuming a sleep state when the channel quality satisfies the first threshold (417), and scanning another data channel for another channel quality value that satisfies a second threshold when the channel quality does not satisfy the first threshold (415).
