Patent 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.
