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.
