Wideband integrated Voice/Data technology

An important challenge in the design of future military communications networks is to achieve overall system economy and adaptability through efficient and flexible allocation of common network resources to voice and data users. The major objective of the Wideband Integrated Voice/Data Technology Program is to address this challenge through the development of techniques for integrated voice and data communications in digital packet networks which include wideband common user satellite links. This report covers work in the following areas: development of a generalized compact vocoder based on digital LSI technology; development of Packet Voice Terminal (PVT) and local access network (LEXNET) facilities for experiments in packet voice; development and experimental application of a flexible internet stream gateway (the miniconcentrator) for packet voice; coordination and execution of multi-user packet speech experiments on the experimental wideband satellite network (WB SATNET); and development and experimental testing of a Voice-Controlled Operator (VCOP).
