NTP Servers

The availability of precise timing not only helps meet quality of service targets and increase customer satisfaction, it also ensures more accurate operations and precise billing systems. Our Network Time Protocol (NTP) servers are designed to provide highly accurate timing for all network elements.


OSA 5420 Series

This solution enables timing to be distributed and assured throughout the network and meets stringent frequency and phase synchronisation requirements. What’s more, despite its compact footprint, the OSA 5420 delivers the best holdover performance on the market.

PTP grandmaster, NTP server, GNSS receiver

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 synchronisation 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 synchronisation is no longer a challenge. What’s more, with its NTP server and GNSS receiver capability including multiple synchronisation fan-out options, our OSA 5420 Series is also ideal for deployment in legacy synchronisation architectures.

OSA 5430

Our OSA 5430 is designed to help network operators achieve stringent phase and time synchronisation requirements and is the first IEEE 1588 grandmaster clock device on the market to support PTP, NTP and SyncE over multiple 10Gbit/s Ethernet interfaces.

Advanced high-capacity synchronisation solution

Only our OSA 5430 offers the space and energy savings of hardware redundancy together with the scale needed for today’s expanding and evolving radio access networks. It is also the industry’s first protected PTP-over-10Gbit/s interface for the delivery of frequency, phase and time synchronisation over packet-based networks.

The technology offers enormous capacity, supporting up to 1024 PTP slaves at 128pps and supports multiple interfaces including 16x E1/2.048MHz output expansion panel to provide a smooth migration from legacy to next-generation sync.
