Digital Subscriber Line (DSL) is a family of technologies that transmits digital data over a local telephone network line. For over a decade, DSL has been the most adopted last-mile technology in the broadband market. As it makes use of telephone lines, DSL is the most convenient and cost effective way to enable Internet connections on legacy infrastructure.


Asymmetric Digital Subscriber Line Version 2 Plus (ADSL2+), a technology of the xDSL family, is widely adopted nowadays among other xDSL technologies. Commonly offered in highly-populated metropolitan areas, ADSL2+ is also a favored solution for sparsely populated areas with fewer multidwelling units, where DSL is more cost-effective than FTTH/B (Fiber to the Home / building) solutions. ADSL2+ data rates can be as high as 24 Mbps downstream and up to 1.4 Mbps upstream depending on the distance from a Central Office (CO) to the business or home premise.


Designed to support the wide deployment of triple play services, Very High Speed Digital Subscriber Line 2 (VDSL2) offers ultra-high data rates of up to 100 Mbps (at 500m from a CO), providing sufficient bandwidth for VoIP, HDTV, and on-line gaming services. To maintain the high data rate, a typical deployment scenario of VDSL2 uses FTTB/C (Fiber-To-The-Building / Curb) as its backbone.

D-Link provides an array of ADSL2+/VDSL modems and routers to fulfill the various demands of Service Providers and end-customers. With the support of Remote Support System (RSS), D-Link DSL routers minimize the time needed to troubleshoot problems on home networks, reducing operating costs and service expenses. Compliant with the Home Gateway Initiative Smart QoS, D-Link DSL routers automatically detect the type of connected devices and assign a pre-defined priority for each device. This QoS support allows users to enjoy high transmission for applications such as IPTV, VoIP, and on-line games over the Internet. The D-Link DSL modems and routers provide all the essentials that a home or small office needs to establish a high-speed remote link to the outside world.
