What is DSL?
DSL stands for Digital Subscriber Line because it involves transmitting data in digital form. DSL technology uses ordinary copper telephone wire — the same wire already installed in hundreds of millions of homes and businesses throughout the world — to transmit data at speeds of up to 8 Mbps. DSL is an “always-on” service, with no need to dial an external phone number for connectivity.
DSL is a modem technology that turns your existing phone line into a three-channel data delivery system. One channel transmits voice services, so normal phone and fax usage continues whether or not you are accessing the Internet. A second channel transmits data downstream at high speeds, and a third bi-directional channel transmits data upstream. The downstream and upstream channels carry information to and from the Internet. Therefore, phone or fax calls occurring on the first channel are not affected by your activity. There are modems at each end of the phone line. One is at your home; one is at the Verizon Central Office. Working together, these modems provide a dedicated connection that avoids the need to dial-up for access to the Internet. The modem in the Verizon Central Office points your Internet traffic to the DSL network and on to the Internet. With DSL Internet access, you have a fast connection to the Internet.
DSL stands for Digital Subscriber Loop. It is a name that encompasses a group of technologies, the most common being ADSL, or Asymmetric Digital Subscriber Line. DSL technologies make use of your existing telephone line. It splits the signal into two, one for voice communications and the other for the high speed data connection. The data line uses a range of frequencies not used in normal voice communications.
