Abstract
A telecommunication system for the switching of voice and data controlled by a computer executing a nonprocedural language that allows for the explicit control of interaction between features by the program scripts executing the programs. The program scripts are written in the nonprocedural language that allows for a state definition, an event definition, and an operation definition. The triples automatically respond to the system state and system signal to execute the necessary actions to control the telecommunication system. During the run time of the system, a script whose triples implement a particular feature can control whether or not features of lower precedence are allowed to be implemented by determining whether or not allow the continuation of the processing of the system signals to the scripts of lesser precedence. In addition, a script can control its own deactivation until later conditions are met that allow the deactivation of the script.
