1. A transmission relay circuit for relaying a broadcast signal generated by a broadcast provider to a local loop provider, the transmission relay circuit comprising:

  • a microcontroller; and

    a broadcast signal sensing and discerning circuit communicating with the microcontroller and configured for sensing and reporting a broadcast signal type of the signal received from the broadcast provider, wherein the broadcast signal sensing and discerning circuit comprises;

    an isolation/buffer amplifier communicating with the broadcast signal generated by the broadcast provider;

    a signal detector portion communicating with the isolation/buffer amplifier for detecting a type of broadcast signal generated by the broadcast provider;

    a logic circuit portion communicating with the signal detector for receiving a signal from the signal detector corresponding to the type of broadcast signal detected by the signal detector; and

    a relay responsive to the logic circuit and providing an output signal corresponding to the type of broadcast signal detected by the signal detector.
