What is ADSL?

ADSL (Asymmetric Digital Subscriber Line) is a technology which enables you to use your telephone line for making phone calls, whilst using the same line to access the internet simultaneously. It provides high speed, broadband internet connectivity at speeds of up to 4Mbps per line - and you can bond up to 5 ADSL lines together to increase your download speed to up to 20Mbps.

ADSL uses a telephone line and thus provides a stable, predictable connection to the internet. However, ADSL availability, speed and stability is greatly dependent on your physical distance from the nearest exchange, as well as ADSL port availability on the exchange itself. This leaves a few matters to consider:

• Not everyone will be able to get ADSL.
• Service quality can only be measured on a per client basis - every ADSL line is unique and behaves different from another.

To get ADSL you must already have a normal analogue telephone line - ADSL cannot be installed on prepaid analogue lines. ISS can  then order the ADSL functionality to be added onto your analogue telephone line. The total cost for ADSL is split into four different categories. These are:

• Your analogue line - this is a set monthly fee.
• The ADSL functionality on your analogue line - this is a set monthly fee, decided by the speed of your ADSL.
• Bandwidth - this is a monthly fee which depends on the amount of bandwidth you consume.
• Hardware - this is a once-off fee, normally only necessary for new installations.

Bandwidth can be purchased in a bundled package consisting of a set amount of bandwidth to be consumed every month, or on a pay as you use package where you are billed for the amount of bandwidth which was consumed. The bundled option is the most popular and works out much cheaper per MB than the pay as you use option.

How do I get ADSL?

To enable ISS to process your order for ADSL, you must:

• Verify that your telephone line can support ADSL.
• Visit our ADSL pricing page and decide on the package you require.
• Download and complete the ADSL application form. Once completed, return the application form and supporting documentation (as noted on the download page) to ISS.

ISS will do the rest. We will:

• Arrange the ADSL installation on your analogue line - if required.
• Provide you with the necessary hardware - if required.
• Create your ADSL product, which will be configured with the amount of bandwidth you require.
• Install any required hardware and configure your ADSL credentials.
