Abstract:

Research in the area of packet voice over the past ten years has proven the value of packet technology for voice transmission. Continuing research in this area has led to the development of a packet satellite network for use as a testbed for packet voice telephone services. In order to allow a wide range of users to participate in the testing of this technology, ISI has developed the Switched Telephone Network Interface card to allow interconnection between the packet network and the commercial telephone system. This report describes the design of this device and the discusses the techniques used to implement functions such as soundsilence detection, echo suppression, and dialing.
