  • Addressable tap units for cable television networks and related methods of remotely controlling bandwidth allocation in such networks
    Patent number: 8132222
    Abstract: Addressable tap units for a cable television network include a radio frequency input and a radio frequency output. These tap units may further include a radio frequency receiver that is configured to receive a radio frequency signal input at the radio frequency input. A filter circuit, which may be a plug-in filter circuit, is coupled between the radio frequency input and the radio frequency output. The filter circuit includes at least one filter that filters out signals in one or more frequency bands. The tap units also may include a plurality of switches that select one of a plurality of signal paths through the filter circuit. The plurality of switches may be controlled in response to data contained in the radio frequency signal. The tap unit may also include an alternate radio frequency path that bypasses the plug-in filter module so that signals incident at the radio frequency input traverse the alternate radio frequency path if the plug-in filter module is not installed in the addressable tap unit.
