Abstract
A method and an apparatus for measuring electrical properties of communication lines is presented, wherein the communication line comprises a first line and a second line, wherein the first line is connected to a first line driver and the second line is connected to a second line driver. At least one measurement for determining said properties of said communication line is performed with the first line driver or the second line driver set to a high impedance state. With this method and apparatus, detailed line testing can be performed without the need for additional elements in a communication circuit.
