Abstract
A telecommunication and development system for the switching of voice and data under computer control in a customer programmable environment that allows real-time modification of communication services. The computer program controlling the system is written in a nonprocedural language that allows for the direct control of the telecommunication system on the basis of state definition, event definition, and action definition. Program scripts define a particular feature, and each script consists of a plurality of triples that automatically respond to the system state and signal information to execute the necessary actions to provide part of a feature to the telecommunication system. During provision of telecommunication services, a customer can add new features that not only add new operations to the system, but modify existing operations without interfering with the present operation of the system. This is possible since the nonprocedural language allows for the direct control of interaction between features and provides for the automatic execution of required operations during state transitions. In addition, the nonprocedural language allows a feature or script to control its own de…
