- Commodity name: Gigabit-isolated high-performance DNTS-9S
The DNTS-9S series is a high-performance time server, equipped with an ARMv8 64-bit multi-core processor and a full‑featured Linux server. It supports multiple GNSS systems or a single BeiDou system, making it suitable for environments with a moderate number of clients and multiple physically isolated networks.
Product Features
Time source: Optional support for satellite inputs such as BeiDou and GPS, 1PPS+ToD input, IRIG‑B code input, NTP/PTP input, and more.
Time synchronization output: By default, it provides NTP output, 1 PPS output, 10 MHz output, and IRIG‑B code output; additional output interfaces can be added via optional accessories.
Timekeeping ： Supports a high-performance timing unit, with options for temperature-compensated crystal oscillators and rubidium atomic clocks of varying holdover performance levels, and complies with the Advanced Frequency Holdover Precast Model.
Processor platform ： A domestically developed high-performance 64-bit multi-core ARMv8 processor;
Operating system ： Full-featured Linux server;
Network interface ： It supports 1 to 4 fully isolated Gigabit Ethernet interfaces, with each port equipped with a completely independent CPU, storage space, and operating system environment; there is no communication between any of the network interfaces.
Monitoring platform ： Supports the DNTS-Manager centralized monitoring software and provides multiple monitoring platform interfaces, including SNMP and Syslog.
Suitable for a wide range of application scenarios with a moderate number of clients, particularly in environments that require multiple strictly physically isolated networks.

Product Overview
The DNTS-9S series is a high-performance time server 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‑9S‑GB), and can also be configured with an optional module to support only the BeiDou system (DNTS‑9S‑B). In addition to satellite‑based timekeeping, the series accommodates a variety of terrestrial time‑source inputs, such as IRIG‑B code, NTP, PTP, 1PPS+ToD, and even manual time entry for local holdover. Priority among these multiple 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‑9S relies on its built-in temperature‑controlled crystal oscillator or rubidium atomic clock to maintain accurate timekeeping, continuously providing external time services. Featuring a proprietary all‑digital phase‑locked loop and a sophisticated frequency‑control algorithm, it delivers superior timekeeping stability and more precise time dissemination.
The DNTS-9S 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.
