    The authors present the commercial strategy for introducing ISDN in France. This strategy is based on the favorable technical elements of the French network, and on the past experience of Videotex and Transpac. Market studies appear to be helpful in determining this strategy. This strategy consists of four actions: reducing the cost of terminals; having attractive tariffs; creating a special sales...
