RAD Slide 10 How Does TDMoIP Work? The synchronous bit stream is segmented Headers are added to each segment to form the packet Packets are forwarded to destination over the PSN network At destination, the original bit stream is reconstructed by removing headers, concatenating frames and regenerating the timing TDM Frame TDM Frame Ethernet/IP Packets Packet Switched Network
