RADSL (Rate Adaptive Digital Subscriber Line) is a variant
of ADSL in which the quality of a line is
tested at connection startup, and the modems negotiate the maximum
data rate that can be supported.
The negotiation of line rate
is carried out using a startup handshaking protocol.
Because it is
able to adjust its rate, RADSL can operate over
may lines over which ADSL operation fails.
