DSL-604+ ADSL Ethernet Router User’s Guide

It is important to understand the difference between the SSID and a BSSID (Basic Service Set Identifier) or
Preferred BSSID. The Preferred BSSID is defined by wireless stations to designate an access point used for
access to the wireless network. The Preferred BSSID is the MAC address of the access point. Therefore any
wireless stations (wireless clients) that use the DSL-604+ through the wireless interface must use its MAC
address for the Preferred BSSID. A wireless station that scans the network for available access points may
present the user with a choice of access point identified by their BSSID.
ADSL Technology
Asymmetric Digital Subscriber Line (ADSL) is a broadband technology that utilizes ordinary copper telephone
lines to enable high-speed digital data transmission and interactive multimedia applic ations for business and
residential customers.
ADSL greatly increases the signal carrying capacity of copper telephone lines without interfering with regular
telephone services for faster downloads and more reliable connectivity. ADSL devices make it possible to enjoy
benefits such as high-speed Internet access without experiencing any loss of quality or disruption of voice/fax
telephone capabilities.
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, depending on local telephone line conditions. 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.
