Information on Rate adaptive Digital Subscriber Line Speed
A typical RADSL connection has a speed between up to
1 Mbps on the upstream and downstream links. Some ISPs
deliberately prevent the Rate adaptive Digital Subscriber Line Speed from exceeding 512 kbps.
Higher speeds may be available to customers located close to
the telephone exchange, or those who pay more for high-performance
connections.
Rate adaptive Digital Subscriber Line Speed is not the only limitation on the
user's speed of access: internal congestion in the ISP's network
or congestion in the ISP's external network interfaces can also
reduce speed.
One common approach to the use of RADSL is
to allocate a fixed rate to the downlink, and allow
the uplink rate to adapt to the level of line
noise and interference.
