Secure, reliable, extremely accurate and traceable timing services have never been more important than they are today. In the era of 4G and 5G, precise network synchronisation is critical for nearly all digital networks, and more stringent network stability requirements. Whether you are a company engaged in electronic trading, a telecommunications provider, or a data centre seeking to deliver timing services to tenants, accurate and reliable timing is essential and can make the difference between failure and compliance.

In PDH/SDH networks that require a stable frequency to operate efficiently, independence of your timing can easily be achieved by tracing back to one or more Caesium Atomic Clocks (such as ePRTC). In fact, the current international definition of the second derives from the transitions of Caesium-133. A commercial Caesium Atomic Clock will maintain Stratum 1 timing (1E-11) for the lifetime of the Caesium Beam Tube.

GPS, and now other GNSS sources such as GLONASS, Galileo and BeiDou, has been a major contributor to frequency and time sync in Tier 1 services in telecoms and enterprise for over 20 years. From the release of the first commercial NTP Server – the TymServe 2000 – to the latest generation is capable of serving over 300,000 NTP requests per second in a data centre.
