OSA 5335 Modular PTP Grandmaster Clock

The OSA 5335 Modular PTP Grandmaster is a scalable and high-performance IEEE 1588v2 standard compliant Grandmaster Clock for distribution of frequency, phase and time synchronisation over packet-based network infrastructure including IP/MPLS, Carrier Ethernet, PON and DSL networks. Its carrier-class design provides high client capacity and a wide range of redundancy options to deliver scalable performance and maximum availability.

The device is designed to deliver precise and reliable frequency, phase and time-of-day information in telecommunications, media broadcast and power utility communications applications.

The device comes with universal input modules accepting a wide range of input signals. It can be equipped with up to two GNSS input modules, each supporting GPS and GLONASS to achieve precise synchronisation, therefore enabling operators to meet Stratum 1 requirements without the need to install and manage external receivers or Cesium reference clock sources.

Its modular design accommodates up to three high-capacity PTP modules enabling a total capacity of more than 3000 remote PTP slave clients. Each high-capacity PTP module includes a hardware-based PTP engine with highly accurate time-stamping and supports more than 1000 PTP slave clients in IP unicast mode according to the ITU-T G.8265.1 Telecom Profile.

For management and performance assurance, the SyncViewPlus management software provides powerful fault, configuration, inventory, performance and security management of the device through an intuitive graphical user interface either locally or from a remote location.

Benefits include: ITU-T G.8272 Primary Reference Time Clock; supports Synchronous Ethernet timing signals including the Ethernet Synchronisation Message Channel (ESMC) and optional NTP server; intuitive graphical user interface enables full management via SNMP and TL1.
