What is DSL?
DSL (Digital Subscriber Line) is a service that offers a faster Internet connection than a standard dial-up connection. DSL technology uses existing 2-wire copper telephone wiring to deliver high-speed data services to homes and businesses.
DSL uses the existing phone line and in most cases does not require an additional phone line. This gives "always-on" Internet access and does not tie up the phone line. No more busy signals, no more dropped connections, no more waiting for someone in the household to get off the phone. DSL offers users a choice of speeds ranging from 144 Kbps to 1.5Mbps. This is 2.5x to 25x times faster than a standard 56Kbps dial-up modem.
This digital service can be used to deliver bandwidth-intensive applications like streaming audio/video, online games, application programs, telephone calling, video conferencing and other high-bandwidth services.
