- Commodity name: Gigabit Isolated Entry-Level DNTS-7
The DNTS-7 series is a high-performance time server designed for cost‑sensitive applications. It supports multiple GNSS constellations, features an ARMv8 64‑bit processor and the Linux Server operating system, and is well suited for low‑cost deployments that require a fixed outdoor receiving antenna.

Product Features
Time source: Optional support for BeiDou, GPS, and other satellite inputs, as well as 1PPS+ToD inputs, etc.;
Time synchronization output: NTP output and 1PPS output are provided by default;
Timekeeping: High‑performance timing units are not supported; an onboard TCXO can be optionally used for short‑term holdover.
Processor Platform: A domestically produced 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 use cases that require the deployment of a fixed outdoor receiving antenna and have low-cost requirements.
Product Overview

The DNTS-7 series is a high-performance time server product developed by Beijing Zhongxinchuang Technology Co., Ltd.

This product series supports the acquisition of high‑precision timing information via all GNSS satellite systems, including GPS, BeiDou, GLONASS, and Galileo (DNTS‑7‑GB), and can also be configured with an optional accessory to provide a single‑BeiDou‑only solution (DNTS‑7‑B).

When using a GNSS satellite receiver, priority levels can be configured; it supports single-receiver, single-antenna setups, and the receiver can independently configure its timing mode. In the event of satellite signal loss, it provides short-term time‑keeping output capability.

The DNTS-7 can also serve as an expansion clock for other models, such as the DNTS-9S, by cascading via a dedicated interface. This enables unlimited, low-cost expansion of output interfaces within the same rack, making it ideal for field applications involving numerous physically isolated networks.

DNTS-7 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.
