Abstract:
1. A method of reporting an accurate count of outage minutes during a predetermined time period in a Synchronous Optical NETwork (SONET) facility, predetermined time period defined as including a sequence of time intervals of a predetermined length, the method comprising the steps of: defining a plurality of transport communication elements included within the SONET facility; organizing the defined plurality of transport communication elements in a hierarchy from the greatest number of bits per minute transported, defined as the highest level in the hierarchy, to the least number of bits per minute transported, defined as the lowest level in the hierarchy; ascertaining any planned maintenance outages during the predetermined time period; designating all recorded outages for each transport element during the predetermined time period; comparing the recorded outages to the ascertained planned maintenance outages for each element and deleting all overlapping minutes from the recorded outages for that particular element; comparing all recorded outages occurring during that same time interval and retaining only the minutes associated with the element at the highest level in the hierarchy; counting all remaining outage minutes to define the accurate count of outage minutes; and generating an outage impact report of the defined accurate count of outage minutes.
