Gigabit Non-Isolated DNTS-9SC

The DNTS-9SC series is a high-performance time server, featuring a standard 19-inch 1U form factor. It supports multiple GNSS systems or a single BeiDou system and incorporates an internal temperature-compensated crystal oscillator for timekeeping, making it ideal for cost-sensitive applications where rack‑mount U‑space is limited.

- Commodity name: Gigabit Non-Isolated DNTS-9SC
The DNTS-9SC series is a high-performance time server, featuring a standard 19-inch 1U form factor. It supports multiple GNSS systems or a single BeiDou system and incorporates an internal temperature-compensated crystal oscillator for timekeeping, making it ideal for cost-sensitive applications where rack‑mount U‑space is limited.

Product Features
Time source: Optional support for satellite inputs such as BeiDou and GPS, 1PPS+ToD input, IRIG‑B code input, NTP input, and more.
Size: Standard 19-inch 1U;
Time synchronization output: By default, NTP output, 1PPS output, and IRIG‑B code output are provided.
Timekeeping: Standard configuration includes a temperature-compensated crystal oscillator timing unit, supporting universal digital frequency‑locking technology; optional configurations feature a temperature‑controlled crystal oscillator or a rubidium atomic clock timing unit, with the option to support an advanced frequency‑keeping prediction model.
Processor Platform: INTEL® x86-64 processor;
Operating System: Full-featured Linux server;
Network Interface: 6 onboard 1 GbE RJ45 network ports;
Monitoring Platform: Supports the DNTS-Manager centralized monitoring software and provides multiple monitoring platform interfaces, including SNMP and Syslog.
Suitable for cost-sensitive applications with moderate network performance requirements and limited rack space.
Product Overview

The DNTS-9SC 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‑9SC‑GB), and can also be configured with an optional accessory to operate as a single‑BeiDou‑only device (DNTS‑9SC‑B). In addition to satellite‑based timing, the series accommodates multiple terrestrial time‑source inputs, such as IRIG‑B code, NTP, 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‑9SC relies on its built-in temperature‑compensated oscillator to maintain accurate timekeeping and continues to provide uninterrupted time services. Its proprietary all‑digital phase‑locked loop technology and frequency‑steering algorithm deliver superior timekeeping accuracy and more precise time dissemination.

The DNTS-9SC can provide precise, standardized time signals for distributed networks, computer security systems, file management systems, e‑commerce platforms, B2B systems, cloud computing centers, large‑scale 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.
