Abstract

Abstract A system for determining the physical location of a home terminal unit senses that a cable carries a communication signal from a home terminal unit to an optical network unit. The system includes the home terminal unit, the optical network unit, and a cable that connects the home terminal unit to the optical network unit. Additionally, energy detection circuitry associates with the cable to detect the presence of a communication signal on the cable and generates a detection signal in response to detecting the energy on the cable. Status circuitry for reading the detection signal connects with the energy detection circuitry and communicates the detection signal from the energy detection circuitry to the telecommunications network.
