  • Early warning fault identification and isolation system for a two-way cable network
    Patent number: 7930725
    Abstract: A system and method for determining an operational status of a segment of a hybrid fiber coax (HFC) cable network. Subscriber premises units (SPUs) connected to the HFC cable network are “pinged” and their responses recorded. The two most responsive SPUs in each node of the HFC cable network are identified. The most responsive SPU is added to a primary ping list and the next most responsive SPU is added to a secondary ping list. The SPUs on the primary list are “pinged” and their responses recorded. If an SPU on the primary list fails to respond, the secondary SPU associated with the node is pinged. If both the primary and secondary SPU associated with a node fail to respond to the “ping,” the node is identified as non-responsive. If all of the nodes associated with a modulator (or a demodulator) are identified as non-responsive, the modulator (or demodulator) is identified as “non-responsive.” Additionally, network devices are pinged and their responses noted.
