The TELEPHONE system was originally designed to carry the voice along copper telephone wires. The voice is converted into small electric pulses which travel along the telephone wires. These electric pulses are then converted back into sound at the other end, so the other person can HEAR you. This happens in both directions so you can have a CONVERSATION.

ADSL also works through the copper wires of your telephone line. However, Internet data travels along the wires at a different frequency to the voice SIGNALS. When ADSL is installed a micro-filter is plugged into your phone connection which separates the frequency of voice signals (telephone line) from that of your Internet data (broadband connection) and it is this that allows you to surf the web and talk on the phone at the same time.
