Information on Asymmetric Digital Subscriber Line (Asymmetric digital subscriber line)
Asymmetric digital subscriber line allows broadband data services
to be carried on conventional copper pair telephone cables. The
capacity provided depends on the distance between the subscriber's premises
and the local telephone exchange; Asymmetric digital subscriber line provides higher capacities
for subscribers who are closer to the exchange
The term "asymmetric"
in Asymmetric digital subscriber line refers to the difference in uplink and
downlink capacities; typically a much higher capacity is provided for
the downlink than for the uplink.
