The diagram below shows the use of the VFX-250S in a video-conferencing over frame relay application. In this application the VFX-250S takes the H.320 datastream from the end point video-conferencing equipment and packetises it into a frame relay format for transmission over the network. This application also includes a MCU (Multi-point Conferencing Unit) which can interface with multiple VFX-250S units.
