I-SCOUT

an electronic device which aids in the location of ingress and common path distortion in a bi-directional cable television network plant, and which is to be installed at a particular location in the cable television network plant to encode electrical signals, including ingress and common path distortion signals, that emanate from a zone downstream of the particular location, the encoded signals being encoded with an identification code and being detected upstream of the particular location where the identification code is identified and the zone from which the encoded signals emanated is determined
