ADSL (Asymmetric Digital Subscriber Line) is a high-speed Internet access service that utilizes existing copper telephones lines to send and receive data at speeds that far exceed conventional dial-up modems. ADSL uses standard telephone lines to transmit upstream and

downstream data on a digital frequency, which sets these data streams apart from the analog signals telephones and fax machines use. Because the ADSL signal is operating on a different frequency, the telephone can be used normally, even when surfing the Web with ADSL service. Click here for more information about ADSL Services.
