Common use of Design Blocking Criteria Clause in Contracts

Design Blocking Criteria. 2.1.9.1 Forecasting Trunk projections and servicing Trunk requirements for Interconnection Trunk Groups shall be based on the average time- consistent busy hour load of the busy season, determined from the highest twenty (20) consecutive average Business Days. The average grade-of-service for Interconnection final Trunk Groups shall be the industry standard of one percent (1%) blocking, within the time-consistent twenty day average busy hour of the busy season. Trunk projections and requirements shall be determined by using the industry standard Xxxx Xxxxxxxxx B.01M Trunk Group capacity algorithms for grade-of-service Trunk Groups. (Prior to obtaining actual traffic data measurements, a medium day-to-day variation and 1.0 peakedness factor shall be used to determine projections and requirements). 2.1.9.2 The engineered blocking objective for common transport Trunk Groups (CTTG) from SBC-13STATE End Office Switches to the access Tandem switch is one-half of one percent (0.5%). The engineered blocking objective for alternate final (AF) Trunk Groups from SBC-13STATE End Office Switches to the local Tandem switch is one percent (1%). The engineered blocking objective for direct Trunk Groups from SBC-13STATE End Office Switches to Carrier's MSC is one percent (1%) for direct final (DF) Trunk Groups and economic centum call seconds for primary high usage groups. The engineered blocking objective for the Trunk Group from the SBC-13STATE Tandem switch to the Carrier’s MSC is one percent (1%). 2.1.9.3 When Trunks exceed measured blocking thresholds on an average time consistent busy hour for a twenty (20) Business Day study period, the Parties shall cooperate to increase the Trunks to the foregoing blocking criteria in a timely manner. The Parties agree that twenty (20) Business Days is the study period duration objective.
