3. PAS Forecasting Work Around Recommendation • NANC 11-19-2002 Action Item: NOWG will consider feasibility of “work arounds” so that carriers can obtain number blocks if request exceeds PAS forecast. • Considered the feasibility of “work-arounds” that would allow service providers (SPs) the ability to be assigned blocks by PAS even if the quantity of blocks requested exceeds the SP’s PAS forecast. • Work-around focused on eliminating the need for an SP to provide the “on the spot” forecast currently required by PAS when the quantity of blocks requested exceeds the embedded PAS forecast. • The NOWG was unable to identify a work-around that could be implemented by SPs. However, the NOWG did identify a solution that may be easily implemented by NeuStar in the short term. • Recommendation: PAS should override and auto-update the SP’s embedded forecast for the current month based upon the actual number of blocks requested and should discontinue the present practice of informing the applicant “Resource Request Denied: Requesting more blocks than forecasted for OCN (XXXX).” PAS would continue to employ its existing logic for pool replenishment, which appears to be triggered by forecasts and not by block assignments.
