What are the main benefits of xDSL?
– Uninterrupted, high-speed Internet access that’s always on-line – Cost-effective solution for residential customers, telecommuters and small businesses – Data Security that exceeds other technologies How does xDSL compare to cable modems? xDSL provides a dedicated service over a single telephone line; cable modems offer a dedicated service over a shared media. While cable modems have greater downstream bandwidth capabilities (up to 30 Mbps), that bandwidth is shared among all users on a line, and will therefore vary, perhaps dramatically, as more users in a neighborhood get online at the same time.

The big difference between xDSL and cable modems, however, is the number of lines available to each. There are no more than 12 million homes passed today that can support two-way
