Aren some DSL services faster?
There are a variety of DSL technologies being developed, but the speed of DSL depends on the length of the copper line from the phone company central office to the installation point. DSL varieties such as HDSL can deliver higher speeds at very short distances, but their limitations make them impractical for dedicated Internet access in most situations. For this reason, AstraGate offers several speeds of SDSL that are appropriate solutions for most businesses and power-users. Another advantage of SDSL is that you get the same speed both up and down stream.
