It features a temperature-compensated crystal oscillator or a rubidium atomic clock timing unit, along with an advanced frequency‑keeping prediction model, making it ideal for industrial control applications and delivering secure, reliable time‑synchronization services over physically isolated networks.
Product Features
Time source: Optional support for BeiDou, GPS, and other satellite inputs;
Time synchronization output: NTP output is provided by default; other output interfaces can be expanded via optional accessories.
Timekeeping: Temperature-compensated crystal oscillator and rubidium atomic clock timing units, supporting advanced frequency‑keeping prediction models;
Processor Platform: Domestically produced high-performance ARM processor;
Operating System: Embedded Linux;
Network Interface: You can select 1 to 8 Gigabit Ethernet interfaces; every pair of ports is associated with a completely independent CPU, storage space, and operating system environment, and there is no communication between any two sets of network interfaces.
Monitoring Platform: Supports the DNTS-Manager centralized monitoring software and provides multiple monitoring platform interfaces, including SNMP and Syslog.
It is suitable for cost-sensitive industrial control applications and can provide secure, reliable time‑synchronization services to multiple physically isolated networks.

Product Overview
The DNTS-9SE series is a high-performance time server product developed by Beijing Zhongxinchuang Technology Co., Ltd.
This product series supports high‑precision time synchronization via all major GNSS satellite systems, including GPS, BeiDou, GLONASS, and Galileo (DNTS‑9SE‑GB). Optional accessories also enable a single‑BeiDou configuration that supports only the BeiDou system (DNTS‑9SE‑B). In addition to satellite‑based timekeeping, the series accommodates multiple terrestrial time‑source inputs, such as IRIG‑B code, NTP, PTP, 1PPS+ToD, and even manual time entry for local holdover. Priority among these diverse time sources can be freely configured.
When using a GNSS satellite receiver, priority levels can be configured, and both single‑receiver/dual‑receiver and single‑antenna/dual‑antenna setups are supported. Each receiver can operate in standalone or combined timing modes. If all time sources lose signal, the DNTS‑9SE relies on its built-in temperature‑compensated crystal oscillator or rubidium atomic clock to maintain accurate timekeeping, continuously providing external time services. Its proprietary all‑digital phase‑locked loop technology and frequency‑control algorithm deliver superior timekeeping stability and more precise time dissemination.
The DNTS-9SE can provide precise standard time signals for distributed networks, computer security systems, file management systems, e‑commerce platforms, B2B systems, cloud computing centers, large database systems, industrial control systems, and more. It has been successfully deployed across government, finance, mobile telecommunications, public security, petroleum, electric power, transportation, industry, and national defense sectors.
