A new synchronization method called Synchronous Frequency Encoding Technique (SFET) is introduced. SFET can be used to recover the source clock frequency when an isochronous service is emulated on an ATM network. By taking advantage of the synchronization of the network, SFET recovers the source clock frequency almost instantaneously. Simulation shows that the recovered clock is independent of the network cell jitter and has jitter performance comparable to that of the present network.
