Broadband

Overview

Broadband or ADSL (Asymmetric Digital Subscriber Line) is a technology for transmitting digital information at a high bandwidth on existing phone lines to homes and businesses. Unlike regular dial-up Internet services, ADSL provides a continuously available, "always on" connection.

ADSL is asymmetric in that it uses most of the channel to transmit downstream to the user and only a small part to receive information from the user. It was specifically designed to exploit the one-way nature of most multimedia communication in which large amounts of information flow toward the user and only a small amount of interactive control information is returned.

In simple terms, the higher bandwidth available (up to 2Mb) transforms an existing telephone wire into a high-speed digital line capable of carrying data at up to 40 times the speed of a conventional modem. This allows you to gain the advantages of high-speed Internet access and data transfer without the cost implications of having a separate dedicated line installed.

How it works?

Broadband service makes use of your existing BT telephone line by splitting the line into two distinct channels: one for voice and the other for the high-speed data connection. The high-speed data connection uses a higher frequency range not used in normal voice communications.

The broadband signal is carried by two specialised modems - one at the user end and one in the local exchange. These modems are designed to exploit the physical transmission capabilities of the copper line to achieve higher data rates over the line than ever before.

A 'splitter' (which is basically a filter) separates the telephony signal from the data signal at the user end and at the exchange end. This allows telephone calls to be made at the same time that data is being sent or received (i.e. a customer can surf the Internet and still make telephone calls), removing the need for customers to purchase a second line solely for Internet access.
