Estimating the term…
A software system written in a nonprocedural language for controlling a telecommunication system in which an internal software signal is generated when a state is exited and another internal signal is generated when a state is entered to control common operations for the state transitions. For each state, a group of instructions written in the nonprocedural language is autonomously executed in response to the exit signal to perform common exit operations for that particular state. A second group of instruction is autonomously executed in response to the entrance signal to perform common entrance operations for that particular state. Various services performed by the telecommunication system are written in scripts of groups of instructions called triples. Each triple has an event definition defining the signal that the triple will respond to and a state definition defining the state in which the system must be in before the triple can respond. Programmer productivity is increased because when new features are added, the common operations previously performed on exiting and entering a state will continue to be performed plus the programmer can add new functions to be performed upon the entrance or exiting from a state without detailed knowledge of the program implementing the previous services.
