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.
