How x2 Works
U.S. Robotics' x2 technology enables analog modems to receive data at up to 56
kbps over the standard analog, public switched telephone network (PSTN). x2
overcomes the limitations imposed on standard, analog modems by exploiting
the digital connections that most Internet and online service providers have at
their end to connect to the PSTN.
The Shift from Analog to Digital Circuits
When the first telephone networks were established, they were completely
analog. Over time, telephone companies began replacing portions of their
analog networks with digital circuits, which provided a higher telephone signal
quality at a more economical price.
Today, the PSTN is almost entirely digital. Typically, the only portion of the
telephone network that remains analog is the line that connects your home to
the telephone company's central office (CO). The rest of the telephone network
is digital.
Client and Server Modems
x2 will not require changes to your wiring and equipment that's already in
place. All that's required to use x2 is a software upgrade.
