ABSTRACT:
An accurate method of reporting “minutes of outage” for a SONET facility applies a set of business rules and hierarchical definitions to delete certain minutes that would otherwise be counted as “outages”. In particular, any outage minutes reported for a network element taken out of service for “planned maintenance” activities are removed prior to performing the final count. Additionally, outage minutes for a “lower level” element (such as, for example an OC1 element) that overlap in time with outage minutes reported for a “high level” element are likewise removed before the count is performed. The elimination of these non-service impacting outage minutes thus results in a more accurate reporting of the actual service impact of the counted outage minutes.
