Abstract
Communications systems will have to support diverse services, which will lead to more complicated software within those systems. This will be a problem particularly because of the system's inability to meet required real-time constraints. This paper describes an object-oriented model based on functional layers for switching systems. Our model enables to improve the productivity, maintainability, and expandability of software while retaining its real-time capability of communications systems. To verify the effectiveness of the model, we implemented it on a computer and telephony integration (CTI) system, and provide the Voice over IP (VoIP) functions.
