A METHOD AND APPARATUS FOR TESTING LINES IN A TELECOMMUNICATIONS NETWORK. |
| 摘要 |
<p>The invention provides a method and apparatus for testing a telecommunications network (1 to 12) 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 (1).</p> |
