Evaluation of landline local loops in Egypt

Abstract

The landline fixed telephone copper network of Telecom Egypt (TE) company is evaluated. A sample of that network is tested using different available tests. The imperfections of the network is discussed and analyzed to specify the reasons for those imperfections. A new methodology to measure the transmission line parameters and determine the Resistance Fault Location (RFL) using “Three Voltmeter Method” is also introduced. The parameters measurement error percentage is acceptable (< 10%) for resistance, capacitance, characteristic impedance, attenuation constant and phase constant. The inductance and conductance suffer from small accuracy values. The RFL measurement has an error percentage of 6.54% for short cable length and small error value. The methodology used the “Three Voltmeter Method” in addition to Data Acquisition System (DAS).
