Network evolution towards ISDN services: a management perspective

Abstract

ISDN (Integrated Services Digital Network) has been recognized by technologists as a major step in the evolution of public network architecture. However, a large percentage of network users do not recognize any bottom line improvements that can result from ISDN nor do they know how to exploit the benefits of the technology. This study evaluates and summarizes the ISDN implementation experiences of nine organizations that are currently using ISDN. Along with their experiences, the study also investigated potential problems and critical success factors associated with ISDN implementation. Understanding these critical issues provides IS management with new insight, enabling them to strategically expedite their ISDN implementation and diffusion.
