  • Telephone line monitoring circuit for providing a visual and auditory signal if the telephone line becomes inoperative
    Patent number: 5062131
    Abstract: A telephone line monitoring apparatus which is used to continuously monitor the telephone line and provide both a visual signal and an auditory signal if the line becomes inoperative. The circuit is designed to be plugged into a conventional telephone jack and monitor the line voltage so that if the line voltage falls below about 6 volts DC or if the line is short circuited or becomes disconnected, the telephone line monitoring apparatus will cause a light emitting diode to flash on and off and further will cause an auditory sounder to emit an audible signal. The light emitting diode is a self-flashing type which serves to modulate the auditory signal.

  • Telephone line monitoring circuitry and apparatus
    Patent number: 5056131
    Abstract: A telephone line monitoring circuitry apparatus which is used to continuously monitor the telephone line and causes a light emitting diode to flash on and off and further causes an auditory sounder to sound loud and soft to provide both a visual signal and an auitory signal if the telephone line becomes inoperative. The light emitting diode is a self-flashing type which serves to modulate the auditory sounder. The monitoring circuitry and apparatus is energized by a DC battery, or by an AC power source with DC battery back-up. The monitoring circuitry and apparatus is designed to have acceptable input impedance and ringer-equivalence and complete isolation to prevent interference with the telephone network.
