Abstract

With the advent of ISDN / OSI products conforming to international standards, interconnectivity or interoperability has been attracting users’ attention over the world. By means of interconnectivity testing, domestic or international, interconnectivity of H. 320 terminals through commercial ISDN networks is getting more and more reliable.

Currently, ratio of successful calls is about 90% according to measurements made by HATS Conference (Japan). This means one out of ten (10) calls will be incomplete on the average. To make users very comfortable with H. 320 terminals, higher ratio is expected and it is well within our reach according to the author’s experience.

In order to realize higher reliability and better utility of H.320 terminals, international cooperation throughout the world is strongly desired.
