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.
