IEEE-1588 and Synchronous Ethernet in Telecom

Service providers are moving from voice services to bundled services, delivering voice, data, video and wireless (quad-play). TDM services continue to represent significant revenue for carriers, and must be supported in this new model. As the network moves to a packet switched infrastructure, there are still applications that require synchronization, e.g.; traditional TDM services, cellular base stations. Timing synchronization is key to distributed networks and it is critical for today´s network environments. As the network services continue to increase, the challenges involved with providing accurate time to systems and applications also increase. This paper addresses the use of IEEE1588^TM in conjunction with synchronous Ethernet to deliver accurate synchronization for the telecom network.
