Frame Relay (FR) represents one of the most important paradigm shifts in modern
telecommunication. This technology is beginning to evolve from data only application to
broad spectrum of multimedia users and potential to provide end users with cost effective
transport of voice traffic for intra office communication. In this project the recent
development in voice communication over Frame relay is investigated. Computer
ssimulations were carried out using the powerful simulation software OPNET. Performance
measures such as delays, jitter, and throughput are reported. It is evident from the results
that real-time voice or video across a frame relay network providing acceptable
performance is possible
