Meet your new Time Server
The NTP2xx and NTP3xx Series NTP Appliances use multiple GPS/GNSS satellite systems to generate a local Stratum 1 NTP Time source for your equipment. The NTP3xx add IEEE1588-2008/PTPv2 Grandmaster functionality for the most demanding networks.
No stupid app, no online accounts, no subscription service, and no Internet needed. Manage and Monitor using CLI, SSH, and a local web browser.
Our NTP/PTP Appliances bring time synchronization to your isolated, disconnected, and air-gapped internal networks, No Internet needed.
Have Internet access, but want a local NTP source? All of our appliances can provide Stratum 1 NTP to your local data center, enterprise, or ISP.
Our products are trusted by ISPs, schools, TV and radio, utilities, governments, enterprises, hobbyists, and others in over 30 countries.
