Major Infrastructure Modifications where CLEC Forecasts its Collocation or Reserves Space. If CLEC’s forecast or reservation triggers the need for an infrastructure modification, Qwest shall take the steps necessary to ensure that it will meet the intervals set forth in this Section, when CLEC submits a Collocation Application. If not withstanding these efforts, Qwest is unable to meet the interval and cannot reach agreement with the CLEC for an extended interval, Qwest may seek a waiver from the Commission to obtain an extended interval.
