What is ADSL and what will it do for me? ADSL (Asymmetric Digital Subscriber Line) is a service applied to an ordinary BT telephone line (PSTN - Public Service Telephone Network). To others it is simply known as “Broadband”. It is a normal pair of BT telephone wires that are permanently connected to your Internet Service Provider (ISP). Broadband enables a standard line to use frequencies far higher than can be heard by the human ear. The use of a simple filter (microfilter) ensures separation of voice and data. These high frequencies carry the data signal, leaving the lower range for normal telephone conversation. As technology improves data speeds are increasing. Some providers (ISP's) boast download speeds up to 8Mb, but 2Mb is the current norm. Advantages: High speed download, quicker connection, always on, fixed price.
