PCT No. PCT/GB95/02802 Sec. 371 Date Apr. 4, 1997 Sec. 102(e) Date Apr. 4, 1997 PCT Filed Nov. 30, 1995 PCT Pub. No. WO96/19072 PCT Pub. Date Jun. 20, 1996The invention provides a method and apparatus for testing a telecommunications network between timed intervals to detect a fault in order to determine an approximate location of a fault. The method comprises measuring a change in capacitance of a line in the network and then determining from a known ratio of capacitance to length of line, a length of line that corresponds to that change. This length will give an approximate location of a fault from a subscriber's equipment located at premises remote from the measuring apparatus. |
