Analysis of ISDN limitations based on the user expectations

The results of a major survey carried out in Switzerland on communications in the 1990s are reported. The results are of particular interest because the participants did not focus on the technical possibilities of telecommunications in their replies. They simply formulated their concrete wishes and expectations. The survey showed that the market potential for ISDN exists, but that implementation is still far removed from customer requirements.

It is concluded that suppliers and network carriers concentrate too heavily on major customers
