Abstract
A method of estimating a physical location of a network fault is provided. Information is received concerning the physical topology of the network by data pulls of information concerning network components and terminal network elements and geographic locations thereof. A network fault is detected by monitoring at least one performance parameter transmitted via upstream communications from the terminal network elements, and a physical location of a network fault is estimated based on the performance parameter, the physical topology of the network, and the terminal network element or elements from which the performance parameter was received that indicated the network fault. A list of network components that require inspection and that may provide a source of the network fault is generated. A signal processing electronic device for mapping the network fault and a non-transitory computer readable storage medium having computer program instructions are also provided.
