Method and system for increasing power savings in a DOCSIS device

Processing circuitry in a user device detects information concerning periodic station maintenance opportunities provided by a CMTS. The processor determines a quiet interval between the end of one station maintenance opportunity and the beginning of the subsequent opportunity. If offsite power to the user device is lost, the processor counts down a predetermined amount of time with a first timer and then periodically turns off RF circuitry of the device after the ending of a maintenance opportunity that follows the counting down of the first timer. The processor then begins a second timer to count the quiet interval. After counting down the quiet interval, the processor restores battery power to the RF circuitry for the duration of the maintenance opportunity. If an off-hook condition occurs while the second counter counts down the quiet interval, the processor restores battery power to the RF circuitry.
