Abstract
The identification of the path and termination points of copper landlines is performed through the use of natural events without the aid of network provisioning information. At least one sferics detector detects at least one sferics event. A listening device, which may be separate from, or integrated with, the sferics detector, is attached to at least one wire that is capable of detecting a noise related to the at least one sferics event. A computing device, possibly attached to the listening device, is capable of matching the noise to the at least one sferics event. The computing device is further capable of determining the location of at least part of the wire based on the location of the listening device and locations of at least two sferics events.
