    摘要: The disclosed system includes a declarative language construct for use in programming telecommunications switching systems, comprised of certain natural language elements such as subjects, predicates and objects. The disclosed system also includes an efficient method for constructing prototype telecommunications system software that provides the capability to handle the real-time and parallel nature of operations in telecommunications systems (Figs. 1-3). In yet another aspect, the disclosed system provides a layered software architecture (Figs. 8 and 9) for use in connection with telecommunications switching systems that enhances overall system functionality.

    摘要: The present invention relates to methods and devices for such control and supervision of an oscillator signal from a controllable oscillator that is done mainly to control the frequency variation of the oscillator signal. According to the invention, the controllable oscillator is controlled by a controlling voltage, which in turn is modified by a correction signal, generated in a control loop. A time discrete representation of a secondary phase is generated in the control loop, the secondary phase corresponding to a frequency being the difference between the frequency of the oscillator signal and a constant frequency. A time discrete approximation signal is generated in dependence of the time discrete representation of the secondary phase. A time discrete error signal is generated in dependence of the time discrete approximation signal, the time discrete error signal indicating the difference between the actual frequency slope of the oscillator signal and a desired frequency slope. The correction signal is generated in dependence of the time discrete error signal. The control loop can also be adaptive, meaning that data from one control sequence is being used in a later control sequence.
