What is ADSL and how does it work?
ADSL (Asymmetric Digital Subscriber Line) is a high-speed Internet access service that uses your telephone line to send and receive Internet data at much faster speeds than a conventional dial-up connection. With ADSL you are connected to the Internet 24 hours a day ("Always On"). You no longer need to dial up to open your Internet connection. You can also make and receive telephone calls while online. The "asymmetric" in ADSL refers to the fact that the data being received by your computer from the Internet (downstream data / downloading), travels at a faster speed than data travelling from your computer to the Internet (upstream data / uploading).
ADSL works through the copper wires of your telephone line. However, Internet data travels along the wires at a different frequency to the voice signals. Your ADSL connection comes through the SPTC phone line network, directly to your house, so it is the most popular type of broadband available.
How fast is ADSL?
ADSL is fast. Compared to a dial-up modem, which does 33kbits per second upstream and (in theory) can do 56kbits per second downstream, ADSL is up to ten times faster. That means that a large download that might take ten minutes on a dial-up modem will happen in around a minute on ADSL.
