ADSL Subscriber/Loop Qualification • Typically an automated process Self directed, Web-based for individuals Bulk load and batch process for corporations Third-party test equipment available 2H ’99

• Rule of thumb for one key customer Relaxing ADSL disturber model 1 db or adding 1k feet of reach = 100k new loops

On Average, Less Than 5% of the Copper Loops Qualified Require Conditioning 207 1111_06F9_c1
