1. A two way communication system comprising:

  • a local host having a first primary broadband communication channel and a secondary out of band transmitter; and

    customer premises equipment having a primary communication channel for communicating with said first primary broadband communication channel of said local host and a secondary low power out of band receiver that receives out of band control signals from said out of band transmitter during low power operation of said customer premises equipment;

    wherein said customer premises equipment further comprises one or more peripherals that provide two way communication with one or more communication devices coupled to said customer premises equipment and a processor that monitors activity level of said customer premises equipment and requests a sleep command from said local host when said peripherals have been inactive for a predetermined duration; and

    wherein said local host further comprises a host processor that processes said request for sleep command and grants said request in absence of traffic for said customer premises equipment and wherein said host processor activates a downstream filter that buffers communications addressed to said customer premises equipment when said customer premises equipment has been placed in low power mode.
