ISDN ( Integrated Services Digital Network) is in a state of rapid growth in Europe. ISDN combines the application of voice, text, illustrations and data in a single network. Thus, only a single ISDN connection is needed for access to a variety of telecommunications services such as telephone, fax, file transfer utilities, etc. The high transfer speed, error-free transmission, quick connect times and growing popularity make ISDN attractive not only for newcomers to data communication, but also for users who have until now depended on analogue Modems.

ISDN operates through the already installed telephone lines to the end device. The main difference with respect to the current telephone network is that signal transmission is entirely in digital form, right up to the end device. Data communication between central and local exchanges is already fully digital.
