1.1 Product Overview
DSL (Digital Subscriber Line) refers to a technology used to increase the data capacity
of standard twisted-pair wires that are generally used to connect most households to
the telephone network. In addition, this technology allows simultaneous voice and
high-speed data transmission over a single pair of telephone wires.
ADSL (Asymmetric Digital Subscriber Line), as its name indicates, is an asymmetrical
data transmission technology with higher traffic rates downstream and lower traffic
rates upstream. It is suitable for Internet users because information is usually
downloaded more often than uploaded, such as when surfing the web or downloading
files.
The Aolynk ADSL2+ router with embedded ADSL2+ technology brings up high-speed
internet access and remote connection features, which make it an ideal solution for
small businesses and SOHO users.
DR811/DR814 uses the ATM over ADSL2+ technology to communicate with the central
office providing the ADSL2+ service. As ATM PVC supports connections of various
types such as PPPoE, PPPoA, IPoA and bridge, Aolynk DR811/DR814 delivers great
networking flexibility and accommodates diversified requirements.
This type of router falls into 4 models as below.
