Voice Switching Control System (VSCS) for Air Traffic Control System for Small Airport

This paper will explain development of IP-based Voice Switching and Control System (VSCS) testbed. VSCS is a component of ATC that provides voice communication facilities as well as recording on the Controller Working Position (CWP) of an Air Traffic Control (ATC) System. Conventional and dominant VSCS technology is currently based on Circuit Switching (CS) and Time Division Multiplexing (TDM) technology. With the development of Packet Switching (PS) technology with TCP / IP protocol, complex and expensive VSCS systems with CS technology can be replaced with more modern and inexpensive systems based on Voice over IP (VOIP). The advantages of IP-based VSCS systems are also easier to integrate with other CNS (communication, navigation, surveillance) components through TCP / IP packet networks. The expensive and complex CS and TDM-based VSCS technologies also make it inappropriate for implementation in small and medium airports in Indonesia. Therefore, in this study, a prototype of IP-based VSCS testbed will be developed for small and developing Airport using VoIP technology.
