Operating cable modems in a low power mode

摘要

An apparatus may include a receiver configured to receive chunks of data on a downstream channel from a cable modem termination system. The receiver may be further configured to enter a low power state in which the chunks of data cannot be received. Wake up circuitry may be configured to monitor data in the downstream channel for a wake up signal when the receiver is in the low power state.
