Abstract: The advancements in embedded systems with mixed signal technology have not only benefited various civil applications but also defence, especially in communications and networking. ICS is an integrated communication system developed for Naval ships to cater to their onboard external communication requirements. It consists of various types of radios to be interfaced by using generic gateways along with the User Access Terminals to enable communication from. ICS system and its interfaces got evolved along with the available technologies. The development of ICS started during early 80’s, initially with a centralized switching based system with analog based terminals. During late 90’s, utilizing the 10Mbps LAN technology for both voice and data, ICS MK-II was developed. There a generic microcontroller based User Terminal was developed to combine the functionalities of various terminals. Now in a pursuit to upgrade the existing system, an IP based system called AICS is being developed to satisfy all the basic and emerging communication requirements of Navy. Communication Access Terminal (CAT) and Radio Interface Unit (RIU) are the two main units being designed for providing user’s and radio’s audio and data interface respectively to Ethernet network, enabling communication through VOIP sessions. This project focuses on design and development of upgraded Interface and Switching Board (ISB) for final prototypes of CAT and RIU.
Keywords: ICS, CAT, Radio Interface Unit, Interface and Switching Board.
