What is ADSL?

Asymmetric Digital Subscriber Line (ADSL) technology provides high-speed data access across a telephone line (copper-twisted pair) by making use of previously unused frequency bandwidth above the voice frequency band. By placing the ADSL signal above the frequency of the voice signal, ADSL service is able to coexist on the same line with your telephone service. ADSL is asymmetric because it provides a higher data rate in the downstream (internet provider to your computer) direction than in the upstream (computer to internet) direction. Asymmetric operation is ideal for home and small office use where files and information are downloaded to the computer more frequently than uploaded.

Protocol and Device Driver Selection

The ADSL USB (Universal Serial Bus) Modem can be easily connected to a USB port on a computer via a standard USB cable. The ADSL USB Modem is fully software upgradeable so that new features and updates may be added by simply loading a new version of the device driver onto your Personal Computer (PC).
