document.writeln('<DIV> 	<dd> 		A technology developed by U.S. Robotics (now 3COM) for delivering data rates up to 56  		<A href="../k/default.asp?name=kbps">Kbps</A> over plain old telephone service  		(POTS). It was long believed that the maximum data transmission rate over  		copper telephone wires was 33.6 Kbps, but X2 achieves higher rates by taking  		advantage of the fact that most phone switching stations are connected by  		high-speed digital lines. X2 bypasses the normal  		digital-to-analog conversion and sends the digital data over the telephone wires  		directly to your <A href="../m/default.asp?name=modem">modem</A> where it is decoded.      </dd> </DIV>');
