High speed broadband connection enabling download speeds of 2Mb per second - around 40 times faster than a standard 56k modem.
An abbreviation of Asymmetric Digital Subscriber Line. ADSL is a technology that transforms a standard twisted pair of copper wires telephone line into a high-speed always on, internet connection capable of simultaneously carrying voice and data. It is termed 'asymmetric' because data moves in one direction faster than in the other i.e. data is transmitted faster from the exchange to you rather than from your premises to the exchange.

Calls made through a VOIP system are typically cheaper than through a regular telephone line.
A device which allows more than one PC to use a broadband connection at the same time wirelessly. You are able to use such a device with your Hebrides.Net connection as long as it has an Ethernet connection that you can plug the IDU into.
