What is ADSL and how does it work?

ADSL is a digital communications system that operates over a standard BT telephone line. The communication is made possible via two ADSL modems - one at the user premise and one at your local BT exchange.

A 'splitter' (or Micro Filter), separates the telephone voice signal from the digital ADSL signal, and allows telephone calls to be made at the same time as data is being transmitted on ADSL.

In order for you to use ADSL in your Home/Office PC - you must utilise a Router/Modem and one or Micro Filters.

The micro filters should be placed between the wall socket and your telephony equpment - such that no telephone device is connected direct to the telephone service.
