Our OSA 5410 Series is a family of compact and costeffective synchronization distribution and assurance devices that brings the power of Syncjack™ to any access network. The OSA 5410 Series offers unique flexibility by supporting delivery and assurance of synchronization utilizing Synchronous Ethernet and IEEE 1588v2 Precision Time Protocol (PTP). Thanks to its builtin Global Navigation Satellite System (GNSS) receiver and Grandmaster (GM) Clock capability, it can be used as a timing source for frequency, phase and time-ofday delivery, as well as a measurement reference for Syncjack™ tools. Our OSA 5410 Series supports Assisted Partial Timing Support (APTS) for the most stringent timing applications. An internal high-quality oven-controlled crystal oscillator (OCXO) or a rubidium oscillator option enable extended holdover capabilities. Applications The family members of our OSA 5410 Series can be utilized in a variety of network synchronization applications, including IEEE 1588v2 Access Grandmaster, Boundary and Slave Clock, APTS Clock, GNSS receiver and Primary Reference Time Clock (PRTC), synchronization signal conversion and sync probe applications. Our OSA 5410 Series is designed to deliver the accurate phase and frequency required by next-generation network technologies such as LTE-A, LTE-TDD and enterprise networks. Timing can be easily distributed and assured throughout a network over existing packet infrastructure. Timing performance is continuously monitored while in service, and alarms are triggered if needed. A valuable new approach for timing distribution is made available to mobile network operators: the ability to effi ciently distribute timing from the network edge and assure that base station clocks precisely track their master. Syncjack™ Monitoring and Assurance Tools Our OSA 5410 Series supports all Syncjack™ functions and tools. Syncjack™ is a comprehensive technology for timing distribution, monitoring and timing service assurance. Syncjack™ Clock Accuracy measures the frequency and phase accuracy of physical clock signals relative to a synchronization reference. Syncjack™ continuously performs Clock Analysis, including frequency and phase accuracy of the PTP packet domain. Syncjack™ also performs PTP network analysis, as well as monitoring and testing the PTP communication path. Our OSA 5410 Series uses Syncjack™ tools to measure frequency and phase accuracy of a physical clock source or a remote slave clock based on TE, TIE and MTIE. It performs PTP clock analysis by calculating TE, TIE and MTIE from timestamps embedded in PTP messages. The network probe function complements the clock measurement through network analysis of the PTP message transport. All functions are supported by our FSP Sync Manager, an advanced management platform for timing distribution and assurance.
