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.
