There are several different types of DSL technology, offering speeds from 15 to 50 times faster than today's analog modems. The speed at which homes and businesses can send and receive text, video and other data depends, in part, on how far away they are located from the central office where the D-slam is installed. DSL speeds run up to 1.5 Mbps at this time. Faster DSL speeds are under development. The maximum speed will depend on such factors as the distance between your home and the TTE serving office and the condition of your line.
Cable modems offer service over a shared cable.
Tens and possibly hundreds, of users may be connected to this local cable line. Access speed is compromised as more users access a cable data network. The capacity available to any one user inevitably drops. The DSL technology provides a dedicated service over an existing telephone line. Because DSL provides dedicated service you don't have to share your access connection with other users and therefore you see more consistency and persistency in your connection.
