A typical RADSL connection has a speed between up to
1 Mbps on the upstream and downstream links. Some ISPs
deliberately prevent the RADSL speed from exceeding 512
kbps. Higher speeds may be available to customers located close
to the telephone exchange, or those who pay more for
RADSL 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.
