12、,000 6. Average Demand Pool 1-5 6,000,000 7. Months of Average Demand 6/2 60 8. Months to Exhaust 4+7 70 Step 1 The quantity of spare numbers provided by SMT is 8,000,000. Step 2 Average demand as provided by SMT is 100,000 numbers a month. Step 3 The OBF SNAC with input from SMT has determined that
13、 200,000 should be used as an estimated monthly accelerated demand. Step 4 The OBF SNAC with input from SMT has also determined that 10 months should be used as the estimated number of months there will be accelerated demand during the remaining months to exhaust. Step 5 The total quantity of number
14、s used during the estimated 10 months of accelerated demand is 2,000,000. (10 months X 200,000) Step 6 The spare numbers minus the total accelerated demand equals the total quantity of numbers used during the months of average demand. ( 8,000,000 - 2,000,000 = 6,000,000) Step 7 The average demand po
15、ol divided by the average demand will give the number of months of average demand. ( 6,000,000 / 100,000 = 60) Step 8 The number of months of average demand plus the estimated number of months of accelerated demand equals the total months to exhaust. ( 60 +10 = 70) Since there is an estimated 70 mon
16、ths to exhaust, the projected announcement date of the new NPA is 40 months away. The new NPA would be available for assignment to REPS ORS 27 months after the announcement date. Toll Free Exhaust Relief Planning Guidelines ATIS-0300057 July 1998 _ 4 3. Explanation of Forecast Model 1. Spare - This
17、is a value tracked monthly by SMT. Spare = value provided monthly by SMT 2 . Average Demand - The Average Demand is the actual average demand provided monthly by SMT. Average Demand = value provided monthly by SMT monthly 3 . Accelerated Demand - Accelerated Demand is an estimate provided by the OF
18、SAC with input from SMT of demand for numbers during a month when there is higher than average demand. This number is used to add a factor above average demand such as would be expected as the current resource is exhausting. One method of deriving the accelerated demand is to use historical data. Ex
19、amples of this are the average of the previous 10 high months or average of the 5 previous high months. Accelerated Demand = provided by OBF SNAC with input from SMT 4 . Months of Accelerated Demand - This is an estimate provided by the OBF SNAC with input from SMT of the number of months there may
20、be accelerated demand as per item 3. Months of Accelerated Demand = provided by OBF SNAC with input from SMT 5 . Total Quantity of Accelerated Demand - This value is derived by multiplying the quantity of accelerated demand by the months of accelerated demand. This will give the total quantity of nu
21、mbers utilized during the estimated periods of accelerated demand. Total Quantity of Accelerated Demand = months of accelerated demand X accelerated demand = 6 . Average Demand Pool - The average demand pool is the quantity of numbers used during the periods of average demand. This is derived by sub
22、tracting the total quantity of accelerated demand from the spare numbers. Average Demand Pool = Spare Numbers - Total Quantity of Accelerated Demand 7 . Months of Average Demand - The months of average demand is derived by dividing the average demand pool by the average demand. Toll Free Exhaust Rel
23、ief Planning Guidelines ATIS-0300057 July 1998 _ 5 Months of Average Demand = Average Demand Pool / Average Demand 8 . Months to Exhaust - The months to exhaust is derived by adding the months of average demand to the months of accelerated demand. Months to Exhaust = Months of Average Demand + month
24、s of accelerated demand Announcement Date - The announcement date is the date that the industry announces the relief NPA and its availability date. The announcement is triggered when the Months to Exhaust = 30. Announcement Date = The date that Months to Exhaust = 30 Availability Date - The availabi
25、lity date is the date that the relief NPA will be able to be disable by end users. The availability date is 27 months after the announcement date. The twenty seven month network preparation interval used in this document was developed using the most current information available at the time and is subject to change. This interval should be adjusted as vendors and service providers develop additional network capabilities for activating subsequent toll free NPAs. Availability Date = Announcement Date + 27 Months
