01/22/2003NOWG NANC Report3 PAS Forecasting Work Around Recommendation NANC 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 SPs 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 SPs 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.
