Factors involved in a smooth transition to ISDNs

The authors deal with the major issues concerning a smooth transition to integrated services digital networks (ISDNs). It is noted that the goals of technology improvements, cost/performance, effectiveness, user acceptance of ISDN services, conversion of networks´ operation to all digital, and standardization are essential for the economic acceptance by the ISDN user. The uses of ISDNs are not completely known at this stage. Therefore, it is not easy to accurately plan for ISDNs. The authors elaborate on these issues, their possible solutions, and their effects on the developments of ISDNs
