- Commodity name: Non-isolated DNTS-7SC
The DNTS-7SC series is a high-performance time server designed for cost‑sensitive applications. It features a standard 19‑inch, 1U form factor, supports multiple GNSS systems, and incorporates an internally mounted temperature‑compensated crystal oscillator for clock stability. It is well suited to environments where cost efficiency is paramount yet network performance remains a key requirement.

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 equipped with a temperature-compensated crystal oscillator timing unit, supporting universal digital frequency‑locking technology.
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 application scenarios where a fixed outdoor receiving antenna can be deployed, cost sensitivity is a key consideration, there are certain requirements for network performance, and rack‑mount U‑space is limited.
Product Overview

The DNTS-7SC 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‑7SC‑GB). Optional accessories also enable a single‑BeiDou configuration that supports only the BeiDou system (DNTS‑7SC‑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 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‑9 relies on its built-in temperature‑compensated oscillator to maintain accurate timekeeping and continues to provide uninterrupted time services.

The DNTS-7SC 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, power, transportation, industry, and national defense sectors.
