  • Patent number: 7194001
    Abstract: A packet switch router that processes downstream digital information to provide dedicated bandwidth to each subscriber destination on a hybrid fiber coax (HFC) network. The router includes a network module that terminates a network connection, a switch that forwards data from the network module, and a channel module. The channel module includes a switch interface, a cell processing engine, one or more modulators, and a radio frequency (RF) transmitter network. The switch interface forwards packetized data from the switch to the cell processing engine. The cell processing engine organizes the packetized data into multiple data streams, encapsulates data in each stream into data cells, and multiplexes the data cells into a multiplexed cell stream. Each modulator is configured to modulate a multiplexed cell stream into an analog signal. The RF transmitter network up converts and combines a plurality of analog signals into a combined electrical signal for transmission.

  • Patent number: 6891841
    Abstract: A communication system is disclosed for providing dedicated bandwidth to at least one subscriber location for transmitting to a common point of distribution via an HFC network. In an embodiment of the invention, the communication system includes a channel interface module and at least one gateway coupled across the HFC network. The channel interface module is located at the point of distribution and includes a transmitter that transmits a windowing signal via the HFC network.
