The Isdn Bandwagon Is Coming, But Who Will Be There To Climb Aboard?: Quandaries In The Economics Of Data Communication Networks

Abstract
The Integrated Services Digital Network (ISDN) is a ‘movement’ seeking consensus among vendors and users of telecommunications equipment about future data communication networks. The current literature rarely considers what ISDN will mean for user organizations who are already engaged in building Local Area Networks (LANs) or in establishing connections with existing Wide Area Networks (WANs). This paper analyzes how the interaction between user demands and vendor solutions will shape the ISDN movement. In particular, the economic capabilities, decision making structures, and preferences that organizations have previously developed will influence the success of ISDN. Among the paper's conclusions: The acceptance of ISDN and ISDN services cannot be reliably predicted by examining technical designs. Demands for ISDN services and technology depend on the evolution of complementary and substitute technologies. Public policies may have overwhelming importance for the rate at which ISDN is deployed and the economic characteristics of ISDN services and technology.
