Feature Interactions in Telecommunications III

The demand for better and more convenient communication requires development of a variety of new services as quickly as possible. As the number of services becomes larger, however, feature interactions create incompatibilities between the various functions needed to implement them. In developing telecommunication systems, a large amount of time is spent on software modifications and testing whenever a new function is added. Much of this time is spent detecting and eliminating problems arising from feature interaction. As more services are offered, feature interactions will, it is suggested, become a major bottleneck in the development of software for telecommunications systems. This volume presents opinions on the technical problems involved in feature interactions in telecommunications systems.
