56k

If, after reading this information over, you have further questions about x2, V.90, 56K or ISDN, please email support@sover.net.

x2 from US Robotics (USR) is a way to deliver faster download speeds if one has an x2 capable modem and is dialing an x2 capable number from an x2 capable phone line. x2 is referred to as a "56K" technology, as it is theoretically possible to achieve download speeds of 56 Kbps. In practice we have found speeds in the high 40s and low 50s to be the norm for connections that can use x2. (Note that many phone lines seem to be unable to support x2 at all due to the quality of the phone line itself.)

At one point there was a tremendous debate over what type of protocol to use to deliver these higher speed connections. USR was on one side of the debate with their x2 protocol, and many other modem manufacturers were on the other side promoting the K56flex protocol.

On February 6 1998, the International Telecommunications Union (ITU) announced the V.90 protocol, which should end the debate and provide a universal 56K standard for all modem manufacturers.

As things stand at the moment, SoVerNet supports x2 from USRobotics and V.90 in many areas of Vermont. We expect that within a few months we will have V.90/x2 capable numbers in all locations that we service. For those with K56flex modems, they should contact their modem manufacturer to inquire about upgrading to the V.90 standard. For those using x2 capable modems, the upgrade will be optional, as the V.90 equipment we use is expected to continue to support x2.

Please be aware that many phone lines in rural New England are not able to support these faster connections. We have had many people report tremendous success, but we have also had many folks with good quality lines who can regularly get 28.8 and above, yet are not able to get x2 connections.
