Service providers and network operators are required to meet stringent specifications for frequency and phase/time synchronization in 5G mobile transport networks. In addition, they must address the challenges involved in planning, provisioning, operating, maintaining and providing service assurance for robust and resilient synchronization distribution networks. To succeed, they need new tools that will enable them to automate these functions, simplify network operations and ultimately improve synchronization performance. This white paper summarizes the advanced synchronization protocol control, maintenance and operations capabilities, and synchronization operation, administration and maintenance (OAM) functions provided by the Nokia 1830 PSS Network Elements, which fully implement the recent editions of ITU-T synchronization standards. It also introduces the WaveSuite Synchronizer application, which is part of an optical network management system that provides a holistic view of the end-to-end synchronization services and topology in support of Synchronization as a Service (SyncaaS).
