  • Splitter architecture for a telecommunications system
    Publication number: 20080260142
    Abstract: An interface card adapted to be mounted at the back plane of a splitter chassis. The interface card includes card edge connectors for providing connections with a splitter card. The interface card also includes cable connectors for inputting mixed voice and data, and for outputting data and voice signals. Tracings are provided on the interface card for interconnecting the cable connectors and the card edge connectors. The tracings are configured such that first tracings carrying data signals from the splitter card to the cable connectors do not cross second tracings carrying voice signals from the splitter card to the cable connectors.

  • Amplifier switch controller and system
    Patent number: 5963843
    Abstract: An amplifier switch controller is provided for use in a headend cable transmission system having first and second amplifiers and amplifier input and output paths connected to one of the first and second amplifiers, which becomes the currently activated amplifier. The amplifier switch controller comprises an input sampler for sampling a combined signal on the input signal path and measuring an input signal level. The amplifier switch controller also comprises an output sampler for sampling the amplified combined signal on the output signal path and measuring an output signal level. A program means receives the input and output signal levels and determines whether the currently activated amplifier is not functioning properly. If it is not functioning properly, the program means generates a control signal to a switch.
