It is designed to provide telecom operators with reliable synchronization, using the latest in hardware and software technologies. The OSA 5548C system provides a scalable synchronization solution ranging from 20 unprotected up to a thousand of 1:1 protected outputs. MAIN APPLICATION SDH/SONET Synchronization „«ƒnGPS or Cesium-based PRC System „«ƒnSynchronization Supply Unit (SSU) „«ƒnGPS-based time distribution system Mobile network synchronization „«ƒnPRC for Mobile Switching Centers (MSC) „«ƒnGPS-based time distribution system Next Generation Networks synchronization „«ƒnTime-of Day Server (e.g. NTP, PTP, etc) „«ƒnTiming sources for Sync-E, Ethernet Network Equipment (EEC) HIGHLIGHTS „«ƒnLatest generation of SSU with 6U, 19” or ETSI shelves „«ƒnIntuitive and modular architecture adapted to all telecom node sizes „«ƒnUp to 200 protected (1:1) outputs „«ƒnExpandable System to provide up to 1000 protected outputs (1:1) „«ƒnG.811 PRC with optional dual GPS cards and G.812 Type I, II or III SSU holdovers „«ƒnUniversal Output & Input card design „«ƒnFully manageable with intuitive Local and Remote Graphical User Interface „«ƒnOptional NTP/PTP Time modules „«ƒn1:1 Protection for every card and function Extreme Compactness Each card is only 100 mm tall, contributing to a higher overall port/volume ratio, and therefore reducing the size of the 5548C shelf design to accommodate overcrowded Telecom Hub Rooms and Switching Center rack spaces. High Availability All cards are intelligent and communicate with each other to implement a distributed intelligence message passing system. This approach ensures the absence of single points of failure and reliable uptime.
