Highly accurate master clocks with redundant time reference

Brochures

The NTS-5000 is a PTP/IEEE1588 grandmaster, NTP Stratum1 time server and ePRTC*, PRTC-A & B clock. It supports ref. time from GNSS or external atomic clocks. Server is equipped with Rubidium (Rb) and supports 2x standard (and 2x optional) 1 GbE output SFP, 1x 100/10 Mbps RJ45 for management, NTP/PTP software timestamping. Network cards have own private PTP stack stored inside private FPGA. This approach ensures best cybersecurity and high stability of synchronisation. Product is suitable for any critical infrastructure and datacenter.

The NTS-5000 Rb OCXO is a carrier-grade GRANDMASTER clock with advanced cyber-security capabilities. Server is created from scratch in 2024, keeping 100% backward compatibility to original 2004 appliance. It has built-in dual redundancy for each critical function. It is based on a state-of-the-art FPGA chipset that offers a powerful free space margin for flexible product growth through the coming decades. It offers a technology suite to meet the synchronization needs of evolving Industry 4.0 IT / OT networks - especially 5G, smart grid, data centres, financial markets. The server provides robust synchronization services ensuring accuracy, stability, security and reliability for any wide-area distributed architecture or any critical infrastructure. When used with Elproma’s external LEVEL-2** GPS L1 anti-jamming filter and LEVEL-3** GNSS simulator, the NTS-5000 time server ensures resilient timing, even in GNSS-denied, heavily jammed RF environments. It is PRS / PRC / PRTC compliant. Custom built options grooves to 3U**.
