What is DSL?
DSL stands for Digital Subscriber Line because it involves the transmission of data in digital form. DSL technology uses ordinary copper telephone wire to transmit data at broad- band speeds of up to 7+ Mbps. This is the same wire that is already installed in hundreds of millions of homes and businesses throughout the world. DSL is an “always-on” service, thus eliminating the need to dial an external phone number for connectivity.
DSL (Digital Subscriber Line) 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 sends data upstream.
DSL is an “always-on”, dedicated service, similar to T-1s or Frame Relay, available from ISDN speeds (144Kbps) through T-1 speeds (1.5Mbps), but much less expensive. Like Frame Relay, DSL is distance insensitive within the service area, and with several competing telephone companies, DSL “loop” pricing (the line to your home or office) is significantly less expensive than Frame Relay. DSL speed ranges from 3 to 50 or more times faster than a modem connection. It is a 24 hour, 7 day connection, with no per minute phone charges, no waiting for modems to connect, and no dropped connections. You do not need to purchase a second phone line for DSL. On the same phone line you will be able to use your DSL and phones as you always have.
