HDSL (High bit-rate Digital Subscriber Line Broadband) is
a DSL technology that provides a high rate, symmetric data
communication link over conventional twisted-pair copper cable. HDSL
provides symmetric upstream and downstream data rates of 1.5 Mbps
using two copper pairs and up to 2 Mbps using
three copper pairs. The maximum range of HDSL
is 4.6 km, which usually limits its availability.
Typical applications of
HDSL include feeder segments from local exchanges to
remote nodes, cross-campus connections and as alternatives to T1/E1 repeaters.
