ABSTRACT:
Loop qualification systems and methods involve evaluating Loop Make-Up (LMU) data to determine whether loops qualify for certain services, such as ADSL service or other digital services. The LMU data includes such information as whether the loop is comprised of copper, fiber, is a DLC, the length, resist zone, carrier zone, loading factor, the existence of a DAML, and taper code information. The loop qualification systems and methods obtain LMU data on existing loops and also information on loops that have not yet been completed. Network service providers (NSPs) interface with the loop qualification systems to determine whether certain lines are qualified for a service. The loop qualification systems also include web-based interfaces to allow both the NSPs and end users to make an inquiry as to the capability of a given loop.
