ONET/SDH network synchronization


PTP grandmaster, GNSS receiver and sync probe

ADVA Oscilloquartz OSA 5548c Synchronization Supply Unit (SSU) / Timing Signal Generator (TSG)  is a scalable synchronization solution ranging anywhere from 20 unprotected outputs up to a thousand protected outputs by adding up to four expansion shelves to the core unit. Its ultra-compact footprint makes it ideal for telecom operators to provide scalable network synchronization in over-crowded exchanges. The OSA 5548C SSU/TSG’s distributed intelligence message passing system eliminates single points of failure and guarantees reliable uptime. Core unit and expansion shelves share the same modules, minimizing overall administrative complexity and enabling reduced homologation activity.
