1. A VoIP drop amplifier for connecting equipment to a broadband signal, the VoIP drop amplifier comprising:

  • an input connector adapted for accepting a broadband cable signal from a cable system and returning broadband signals to the cable system;

    a plurality of output connectors, the output connectors having at least one non-essential output connector and at least one essential output connector, the at least one essential output connector including an output adapted for connection to VoIP telecommunication equipment;

    an amplification path connecting the input connector to the plurality of output connectors, the amplification path having;

    a diplex filter for separating the broadband signal into return and forward signals;

    a forward amplifier for amplifying the forward signals;

    a path for the return signals; and

    a splitter for connecting signals traveling on the amplification path to each of the plurality of output connectors;

    a bypass path connecting the input connector to the at least one essential output connector;

    a switching circuit for switching between the amplification path and the bypass path; and

    a dc current and voltage sensing circuit connected to the switching circuit for selecting the bypass path upon the dc current and voltage sensing circuit detecting an abnormal condition, and for selecting the amplification path when the dc current and voltage sensing circuit detects absence of an abnormal condition.
