Introduction
This section provides a brief description of the Router, its associated technologies and a list of Router features.
What is ADSL?
Asymmetric Digital Subscriber Line (ADSL) is broadband access technology that provides high-speed digital
data transmission and interactive multimedia applications for business and residential customers over ordinary
telephone line.
ADSL greatly increases the signal carrying capacity of copper telephone lines without interfering with regular
telephone services. For the ADSL user, this means faster downloads and more reliable connectivity. ADSL
devices enable high-speed Internet access without any loss of quality or disruption of telephone services.
ADSL provides a dedicated service over a single telephone line operating at speeds of up to 8 Mbps downstream
and up to 640 Kbps upstream. A secure point-to-point connection is established between the user and the central
office of the service provider.
D-Link ADSL devices incorporate the recommendations of the ADSL Forum regarding framing, data format,
and upper layer protocols.
