Network transformation, driven by IP services and Ethernet technologies, presents multiple challenges. Equally important to introducing a packet-transport solution in an SDH/SONET network is meeting TDM- or packet-based synchronization requirements. In mobile networks, 3G/LTE mobile technologies with multiple traffic types and synchronization requirements must find common ground for a cost-effective solution. Using a synchronization and timing-distribution strategy based on the interworking of IEEE 1588v2 and ITU-T Synchronous Ethernet, and ensuring synchronization continuity that leverages existing SDH/SONET networks, the Nokia 9500 MPR platform guarantees carrier-class transport while reducing the need for external synchronization sources. This paper explains the functionality and benefits of the synchronization technologies and describes how the Nokia 9500 MPR uses them in mobile backhaul networks.
