Asymmetric Digital Subscriber Line (ADSL) is a new modem technology that enables an ordinary telephone line to reach speeds up to 512kbps (over 9 times that of a dialup connection). It is another connectivity technology that transmits data at a high bandwidth on existing copper telephone lines to homes and businesses. The ADSL system makes use of your existing telephone line and splits the signal into voice communications and high speed data connection. ADSL is capable of simultaneously offering voice information on the same line.
ADSL offers you increased bandwidth. The downstream bandwidth (Maximum 512k) is higher than the upstream (Maximum 256k). Being asymmetric, it means that ADSL uses most of the channel to transmit downstream (refers to the flow of information from the requested information resource to your PC) to the user and only a small part to receive information from the user. Whatever level of your downstream, your upstream level is fixed at 256Kbps.
