Abstract:
1. A computer-implemented method, comprising: identifying a plurality of fiber node ranging delays, wherein each respective one of the plurality of fiber node ranging delays is associated with a respective one of a plurality of broadband devices, and each respective one of the plurality of fiber node ranging delays is based on information received from the respective one broadband device associated with the respective one fiber node ranging delay via a processing device; establishing a plurality of groups of non-overlapping fiber node ranging delays, wherein each respective one of the plurality of groups is associated with a fiber node and comprises one or more of the identified fiber node ranging delays, the groups being established by wiring the fiber nodes such that each fiber node is associated with a unique range of fiber node ranging delays and none of the fiber nodes include overlapping ranging delays with another fiber node, whereby the established groups allow an assurance system to differentiate between fiber nodes based upon ranging delay; determining one or more fiber node ranging delay windows based on the established groups using the processing device, wherein each respective one of the one or more fiber node ranging delay windows comprises a range of fiber node ranging delays identified from one or more subscriber devices associated with one or more fiber nodes, the range comprising the unique ranges of each of the one or more fiber nodes; storing one or more fiber node ranging delay windows in a datastore associated with the processing device; and determining that a fiber node is faulty at the processing device, the determination being based on the presence of a plurality of impaired broadband devices having fiber node ranging delays within the ranging delay window associated with the fiber node that is determined to be faulty.
