Telecom Egypt Company (TE) is the unique copper fixed line network operator in Egypt and its primary aim is to improve the efficiency of this network to face the increasing demand for high data rates communications. The severe fault affects the copper network is the resistance fault. The most commonly used testing and measuring instrument in TE is “Dynatel 965DSP” which has some drawbacks. This paper introduces a new methodology for the determination of Resistance Fault locations of a three resistance faults twisted pair telephone line. This method is based on the three voltmeter method and automated by using NI USB-6281 Data Acquisition Card (DAQ). The simulation results accuracy of one of the faults does not exceed 1.63% for faults up to 100 KΩ and 350 m length cable.
