When HDSL makes senseHDSL is an ideal solution in any situation where dispersed sites need to be connected, and when time, budget and performance are significant factors. It is being used today to provide telephone companies and organizations deploying campus area networks with a way to offer advanced high-speed digital services to end users that previously would have required the installation of other costlier and time-intensive alternatives.The installation of fiber optic or coaxial cable is a long-term and costly proposition. For example, it has been estimated that it would take up to 20 years to reach the majority of customers in a large U.S. regional Bell operating company through the use of fiber optic or coaxial cable. HDSL on the other hand, can reach most of a telephone company's customers almost immediately since the copper infrastructure is already in place.
