What is the V.90 Standard?
Speed equals productivity. The new V.90 standard announced March 1998, replaces two previously incompatible modem protocols--x2 and K56flex. Using the best of the two previous standards, V.90 technology allows modems to receive data at up to 56Kbps over regular phone lines. This new speed is ideal for individuals and businesses that want faster access without having to upgrade to more expensive telephone connections such as ISDN.
How Does it Work?
Dial-up 56Kbps (V.90) access is possible using the new V.90 Standard. The V.90 technology is based on a new transmission technique which bypasses the analog-to-digital conversion in the downstream path so that nearly all of the available 64Kbps network bandwidth is used. Upstream data, which is typically less speed sensitive, travels at the standard V.34 rate.
Do You Always Connect at 56Kbps?
Note that current FCC regulations restrict transmissions to a maximum of 53Kbps. In addition, there are a couple of other factors that can affect the connection speed. Firstly, the speed of connection will vary with the quality of the individual customers' telephone line (this has always been the case with 28.8Kbps or 33.6Kbps modems as well). The V.90 modems will automatically adjust transmission speed as required. Secondly, there can only be one analog-to-digital conversion in the phone network along the path of the call. This means that users connecting through a PBX (e.g. at a hotel) may not achieve 56Kbps (V.90) speeds, because there is typically an extra analog-to-digital conversion for calls through a PBX.
What do I need?
All you need is a modem which supports 56Kbps (V.90) transmission. Information on upgrading and modem selection is available at http://www.56k.com.
