Application of network voice to Navy and DoD telecommunications

摘要

The application of network voice technology to the Navy and DoD telecommunications offers possibilities for highly integrated communications services including voice, data, and video while maintaining interoperability with legacy communication systems. The need for network voice technology can be understood by considering the level of voice integration being achieved in contemporary shipboard backbone networks. Voice transport across shipboard asynchronous transfer mode (ATM) networks being installed under the Navy's Information Technology for the 21st Century (IT-21) initiative is limited to using the ATM Forum's Circuit Emulation standard. Using Internet Protocol (IP) and application programming interfaces (API) for conducting H.323 multimedia conferencing sessions to handle shipboard voice traffic is an attractive option for overcoming this limitation. We identify options available for developing network voice applications for military communication systems. A specific example of applying network voice technology for developing a solution for interoperating with legacy shipboard communications is discussed.
