Driven by the continuing evolution of radio access networks to support higher data rates, increased coverage and better spectrum utilization, cost-effective delivery of assured phase, frequency and time-of-day synchronization at the edge of mobile backhaul networks has become a challenge. Are you struggling with high packet delay variation and delay asymmetries across your mobile backhaul network? Do you have difficulties in meeting frequency and phase synchronization accuracies required by LTE-TDD and LTE-Advanced technology? Our OSA 5420 Series can help. This family of IEEE 1588v2 Precision Time Protocol (PTP) grandmaster devices optimized for deployment at the network edge ensures that cost-effective and accurate synchronization is no longer a challenge. What's more, with its NTP server and GNSS receiver capability including multiple synchronization fan-out options, our OSA 5420 Series is also ideal for deployment in legacy synchronization architectures. Your Benefits O Leading Edge GNSS Receiver Enables PRTC/PRC and grandmaster clock functionality for frequency, phase and time-of-day delivery using multiple constellations O Unique Flexibility Configurable to operate in PTP grandmaster clock, assisted partial timing support (APTS), boundary clock and slave clock mode as well as NTP server and SSU / TSG O High-Availability Design Automatic clock selection, self-calibrating delay asymmetry compensation, power supply redundancy and DoS protection O Extended Holdover Performance High-end quartz and rubidium oscillator options O Syncjack™ Technology Built-in synchronization accuracy monitoring, testing and assurance functionality O Operational Simplicity FSP Network and Sync Manager platform for superior management and sync monitoring capabilities
