Description
Up to 8Mbps Speed
The modem features G.dmt modulation for speeds of up to 8 Mbps downstream and 640 Kbps upstream. G.lite is also supported, allowing up to 1.5 Mbps downstream and 512 Kbps upstream. G.lite is sufficient for most Internet applications today, and has the advantage of not requiring the installation of a splitter at the subscriber end. The modem auto-senses the connection type and auto-negotiates the best modulation scheme, G.dmt or G.lite using the G.hs (handshake) protocol.
Uses Existing Telephone Line
The ADSL modem operates over the existing telephone wire and does not require new transmission media such as fiber-optic cabling. ADSL makes possible high-speed multimedia services, Internet access, and video conferencing for anyone using a standard copper phone line.
No More Busy Signals
ADSL service, once installed, is always on. There is no need to dial the ISP or corporate LAN at the other end.
No Shared Bandwidth
Unlike traditional and cable modems, ADSL does not use shared bandwidth, a phenomenon that reduces connection speed as more users get on-line. With ADSL, the entire bandwidth is dedicated to a single connection.
Maximum Utilization of Resources
Regular telephone service uses only a tiny portion of the actual capacity of a conventional telephone line, while ADSL uses the remaining bandwidth for high-speed data transfer. This is accomplished by setting different frequency channels for different functions, so that voice communication occurs at thelower end of the frequency spectrum, while data transmission takes place at higher frequencies.
Increased Productivity
ADSL makes possible simultaneous voice and data transmission. It also lets users download lengthy documents and graphics files quickly.
USB Interface
This modem provides a plug-and-play interface with the host PC through the USB port, a standard port on many of today's PCs. The modem connects to this USB interface through a provided USB cable.
