Scope
Introduction This document is to be used for forecasting the months to exhaust of the current tollfree NPAs. The months to exhaust will@ in turn@ trigger an announcement to the industry of the relief NPA and the date it will be available. All references to number(s) or NPA(s) in this document are toll-free number(s) or NPA(s). According to Section 2.4@ Service Management System For 800 Numbers@ of the OBF/SNAC Guidelines toll free numbers fit into one of nine categories: NNX Not Open Assigned Transitional Spare Working Suspend Reserved Disconnect Unavailable Spare numbers are defined as follows - The 800 Number is available for assignment by a RESP ORG. The other eight status's for numbers are for those numbers that are unavailable for assignment. This forecast will estimate the months to exhaust of the Spare numbers. There are two factors used in estimating the months to exhaust. The first is the actual monthly average demand which is provided by the SMS800 Management Team (SMT)1@ or its successor. The second is an estimated monthly accelerated demand which is determined by the OBF SNAC with input from SMT. The forecast model uses the actual average demand and the estimated accelerated demand to estimate the months to exhaust of the spare numbers. The SMT will run the forecast model monthly. When the months to exhaust equals 30 months@ the SMT will notify the OBF SNAC of the situation. The OBF SNAC will notify the INC@ in writing@ that the current toll free resource will exhaust within 30 months. The INC will review the OBF SNAC notification and request NANPA: (1) to assign a new tollfree NPA and (2) to announce its availability in 27 months via a NANPA Planning Letter (PL). The INC will provide to NANPA as much detail as possible@ e.g.@ date of implementation@ for inclusion in the PL. Section 2 of these guidelines gives an example of the forecast model using fictitious numbers. Section 3 provides definitions for the items in the forecast model. The items in the model have one of three sources; they are provided by SMT@ provided by the industry@ or are derived from two other values in the model. 1 The SMS800 Management Team (SMT) is comprised of representatives from each of the Regional Bell Operating Companies and is responsible for managing all aspects of 800SMS service.
