A novel method and system for fault identification is provided. A test head that is operable to generate a test signal along a pathway is employed. The test head is based on time domain reflectometry, and is thus operable to provide an estimated physical distance of where a fault occurs along the pathway. The response test signal is matched with a known set of information about the cable and junctions and other components associated with the pathway, including information about the physical location of those components. As part of the matching, an actual real-world physical location can be identified as to where the fault likely occurs, thereby reducing the need for a service technician to attempt to physically locate the fault himself.
