F.C.C. Chairman Calls for Transforming the Technology Used by Phone Systems - NYTimes.com: "The chairman of the Federal Communications Commission said on Tuesday that the agency would begin “a diverse set of experiments” next year that would begin to move the nation’s telephone system from its century-old network of circuits, switches and copper wires to one that transmits phone calls in a manner similar to that used for Internet data. The Internet-based systems allow more information to be transmitted at one time, making possible the addition of video to phone calls, as employed by services like Skype and Vonage. While consumers can already use those services, most of the legacy telephone networks still use analog technology, employing an out-of-date system of physical switches that is expensive to keep operating."
