BellSouth Mileage Authority

• For any distance measurement from/to a BellSouth Central Office, use the V&H coordinates and mileage calculation formula filed in NECA 4. NECA is updated monthly. Ensure that you are using the most current copy.

• For any distance measurement from/to an End User, POP, CLEC Switch, etc. (i.e. any non-BST CO), use a tool like Telcordia® Technologies’ LocateIt product that converts an address to the appropriate V&H before calculating mileage.

• Never use an off-the-shelf mileage PC program to calculate mileage. This information is not updated monthly like the Telcordia® product.

Host/Remote Mileage Calculations

• Common Transport mileage is measured as the sum of the mileage from the Tandem to the Host and the mileage the Host to the Remote, rather than from the Tandem directly to the Remote.

• The common transport mileage in the previous example would be 25 + 15 = 40, not 20.
