Integrated Services Digital Network (ISDN) is a speedy, two-line digital telephone network that works over regular residential and business copper phone systems. With free ISDN access, anyone can benefit from the flexibility and ease of high-speed internet capabilities.

Free ISDN access is fast because of its digital connection, which can manage and transfer information more than four to fives times as quickly as a regular analogue telephone network. This works with the help of an ISDN adapter, which integrates analogue or voice data with digital data, allowing them to be sent at the same time, over the same line, and at the same speed (up to 128 kbps). That means users can upload and download information at the same speed.

The quest for increasingly fast internet links has resulted in the creation of broadband connections that are capable of transmitting high-fidelity images at top speed, but practice dictates that many users don't require that kind of connection. In fact, most tasks undertaken by the average user, such as a student or a small business owner, can be performed with ease using the 'always on' 128 kbps connection that comes with free ISDN access. Some marketers would have you believe faster is always better, but all that speed comes at a steep price. Why pay for lightening-fast service you don't need and wouldn't use? It doesn't make sense.

One of the best advantages of free ISDN access is the ease with which it can be deployed nearly anywhere in the world. ISDN is available in many remote towns and villages that have a digital exchange, but where broadband service has yet to make an appearance.

Before signing up for high-speed broadband service, examine your internet usage to determine whether free ISDN access might be the best option to meet your needs.
