  • Patent number: 5893024
    Abstract: A method and apparatus for reducing ingress noise (304) in the upstream frequency band and reducing power consumption in a cable communication system (200) by not allowing signals generated in the customer premise (104) to enter the upstream frequency band on the cable network (110) unless a customer premise device (102) is attempting to establish a communication link. An RF detector (206) monitors the signals on the coaxial cable for an RF signal. The comparator (208) indicates to the logic circuit (210) when the RF signal has exceeded a minimum threshold. The logic circuit (210) determines if the subscriber premise device (102) is attempting to establish a communication link. If the subscriber premise device (102) is transmitting the logic circuit (210) closes the ingress switch (212) to connect the subscriber premise device (102) to the network.
