Common use of Responsibility of Parties Clause in Contracts

Responsibility of Parties. 51.3.1 The Parties agree to abide by the following if a forecast cannot be agreed to: Local Interconnection Trunk Groups will be provisioned to the higher forecast. A blocking standard of one percent (1%) during the average busy hour shall be maintained. Should the Parties not agree upon the forecast, and the Parties engineer facilities at the higher forecast, the Parties agree to abide by the following: a. In the event that CLEC over-forecasts its trunking requirements by twenty percent (20%) or more, and CenturyLink acts upon this forecast to its detriment, CenturyLink may recoup any actual and reasonable expense it incurs. b. The calculation of the twenty percent (20%) over-forecast will be based on the number of DS1 equivalents for the total traffic volume exchanged between the Parties. 51.3.2 In addition to the joint trunk group forecasting established in Section 51.1, discussions to provide relief to existing facilities can be initiated by either Party. Actual system augmentations will be initiated upon mutual agreement. 51.3.3 Both Parties will perform a joint validation to ensure current Interconnection Facilities and associated trunks have not been over-provisioned. If any facilities and/or associated trunks are over-provisioned, they will be turned down where appropriate. Trunk design blocking criteria described in Section 64.3.4 will be used in determining trunk group sizing requirements and forecasts. 51.3.4 If, based on the forecasted equivalent DS-1 growth, the existing facilities are not projected to exhaust within one year, the Parties will suspend further relief planning on this Interconnection until a date one (1) year prior to the projected exhaust date. If growth patterns change during the suspension period, either Party may re-initiate the joint planning process. 51.3.5 Both Parties will negotiate a project service date and corresponding work schedule to construct relief facilities prior to facilities exhaust.
