System and Method for Qualifying Telephone Lines for Very-High-Bit-Rate Digital Subscriber Line Service

Abstract

A method for qualifying a telephone line for very-high-bit-rate digital subscriber line (“VDSL”) service is disclosed. Generally, a telephone line for VDSL service is prequalified based on a length of the telephone line. A VDSL rate of the telephone line is measured and it is determined whether to qualify as VDSL data qualified based on the measured VDSL rate and a VDSL rate threshold. A VDSL video quality of the telephone line is measured and it is determined whether to qualify the telephone line as VDSL video qualified based on the measured VDSL video quality. Finally, a network database is updated with the determined VDSL data and video qualifications of the telephone line.
