SERVICE ORDER ACTIVITY NOTES:

1. The LRN FID is used to provide Service Management System (SMS) with subscriber routing information when the subscriber's telephone number is associated with number portability. Although the LRN value is drawn from valid NPA-NXX-XXXX number space, it has been specifically selected by Number Administration to represent a geographic/rate center area (perhaps serving many NXXs within the NPA) served by a specific switch. Check with your local Number Administration for valid values.
