How fast are V.90 modems?
With a reasonably good phone line and if you live within 3 1/2 miles from your central office (local phone company building), you should get connect speeds between 40K and 53K. Some lines have impairments on them, like digital pads or robbed bit signaling (RBS), which decreases the highest achievable speeds. However if you are getting pretty good V34 connections, you should be able to significantly benefit from a V90 modem.
