What is the distance limit for DSL service?
Distance limits vary by service type (SDSL, ADSL, and IDSL). The nearer a customer is to the telephone company central office, the more DSL options they have. The appropriate measure of distance is the length of cable, which twists and turns underground, between the customer and the central office. The distance in cable feet is always longer than the distance measured as the crow flies and may not follow logical driving directions.
The distances are measured in cable length, not as the crow flies. Generally the cable connecting a customer to a Central Office does not run in a straight line. Instead, the cable twists and turns underground so the distance measured in cable feet is always longer than the distance measured as the crow flies. The limitations are different for the different flavors of DSL. Customers who are located further from the Central Office than the distances listed below will not qualify for that particular DSL service. All distances are approximate.
