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.
