ISDN — The User’s View

The evaluation of the ISDN from the user—s point of view is intended to show the ways in which the ISDN improves communication in terms of meeting user needs and supporting new applications. It also considers those requirements that will for some time have to remain unsatisfied. In general, it should be emphasized that the ISDN improves communication through simpler operation, improved accessibility as well as easier and faster access to information. These improvements ultimately result in a better communications cost/ performance ratio, a speeding-up of communication processes (and therefore greater productivity) and an improvement in the quality of decisions through being better informed. The three main groups of users, each with their own profile of communication requirements, will be considered separately: people in the office, people at home and people on the move.
