ADSL is an acronym for Asymmetric Digital Subscriber Line

ADSL does not require an additional phone line. With ADSL, your data connection is an "instant on" connection (no busy signals), and is a dedicated, point-to-point connection to a particular service, such as an Internet service provider.

Why is ADSL better than Dial up Modems?

Dial up Modems is a shared medium, unlike ADSL which offers a dedicated line for each user.When too many users in one area try to share the same connection, performance can suffer dramatically as users compete for the limited resources one connection can afford.

Using a shared medium such as modems also creates security problems and modem users are much more vulnerable to data interception, unauthorized monitoring and hacking from other users along the same dial up network.

How does it work?

ADSL operates over an existing telephone line; a new line is not required. The ADSL signal is carried by two ADSL modems - one in your premises and one in the exchange.

These ADSL modems have a splitter (which is a filter) that separates the telephone signal from the ADSL signal. This means that on the same line telephone calls and data is being sent or received (i.e. a customer can surf the Internet and still make or receive telephone calls.

How fast is ADSL?

We expect to offer data transfer speeds ranging from 512 Kbps (thousand bits per second) to 2.04 Mbps (million bits per second).

An ADSL connection is typically at least 8-10 times faster than a 56K modem and at least 8 times faster than single channel ISDN!

What is ADSL?

• ADSL is an acronym for Asymmetric Digital Subscriber Line.
  

• ADSL is a technology that allows data to be transmitted over a dedicated digital circuit using ordinary copper phone lines between a business or residence and a telephone company's central office. ADSL technology transmits at much higher speeds than traditional, analogue technology (Dial up Modems).
  

• ADSL technology can also allow you to make a phone call while transmitting data (while using the Internet, for example) on the same line.
  

• ADSL does not require an additional phone line. With ADSL, your data connection is an "instant on" connection (no busy signals), and is a dedicated, point-to-point connection to a particular service, such as an Internet service provider.
