Potential points of neighborhood node ingress in a cable communication system are identified based on a neighborhood node ingress map. One or more local test signals are then transmitted at or proximate to the potential point(s) of ingress. A local test signal amplitude is received/monitored at or proximate to the potential point(s) of ingress, wherein the amplitude represents a strength of a received test signal based on ingress of the transmitted test signal into one or more faults of the cable communication system. Accordingly, the one or more faults may be identified based on relatively higher received/monitored test signal amplitudes pursuant to transmission of the test signal(s) at or proximate to the potential point(s) of ingress.
