X-Stream is an internet modem technology that transforms ordinary phone lines into high-speed digital lines for ultra-fast Internet access. DSL modems use digital coding techniques to squeeze up to 99% more capacity out of a phone line without interfering with your regular phone services. This means you can be simultaneously talking on the phone or sending a fax - while surfing on the World Wide Web. Unlike a similar service offered over a cable TV line, when using X-Stream you won't be competing for bandwidth with other subscribers.
