D Link DSL-100D PCI ADSL Modem Adapter - Other

Up to 8Mbps Speed: this adapter features a DMT full rate for downstream line of up to 8 Mbps and upstream line of up to 640 Kbps. G.lite rate for downstream line is up to 1.5 Mbps and upstream line is up to 512 Kbps, high enough for most Internet applications today. G.lite support eliminates the need to install a line splitter at the residential end of the line. The adapter auto-senses the installed line and auto-negotiates between the full rate and G.lite.

Uses Existing Telephone Line: the ADSL adapter operates on the existing installed twisted-pair copper telephone wire and does not require new transmission media such as fibre optic cable. ADSL enables high-speed multimedia services, Internet access and video conferencing for everyone using a standard, copper phone line.

No More Busy Signals: ADSL is always on once it is installed. There is no need to dial up to establish a connection to an ISP or to a corporate LAN.

No Shared Bandwidth: unlike traditional or cable modems, ADSL does not use cross-user shared bandwidth, a phenomenon that has a significant detrimental effect on the connection speed as more users get on-line. With ADSL, the entire bandwidth is dedicated to a single connection.

Maximum Utilisation of Resources: regular telephone services use a minimal portion of the actual capacity of the telephone lines, while ADSL uses the remaining bandwidth for high-speed data transfer. This utilisation is accomplished by setting different frequency channels for different functions, so that voice communication happens at the lower end of the frequency spectrum, while data transmission takes place at a higher frequency.

Increased Productivity: ADSL enables simultaneous use of voice and data transmission. It also lets users download lengthy documents and graphical files quickly.
