  • Fault isolation system and method
    Patent number: 7830807
    Abstract: A fault isolation system and method. A hierarchical numbering system is applied to devices within a subscriber network. The number system comprises a continuously concatenated string that provides a relative location of each active device with a subscriber network. The numbering system provides “genealogical” information about network devices and their location with the network and facilitates the correlation of non-responsive CPE data with faults in network devices.
    Type: Grant
    Filed: July 2, 2009
    Date of Patent: November 9, 2010
    Assignee: Time Warner Cable, Inc.

  • Fault isolation system and method
    Patent number: 7573828
    Abstract: A fault isolation system and method. A hierarchical numbering system is applied to devices within a cable network. Each subscriber is associated with a “last active device” or “LAD” providing service to that subscriber. The numbering system provides “genealogical” information about the subscriber's LAD so that the LAD can be located within the network. By correlating trouble reports from subscribers, a fault in an active device can be isolated to a particular segment of a cascade if not a particular active device. The number system comprises a continuously concatenated string that provides a relative location of each active device with a cable network.
