Recently, the Macao Transport Affairs Bureau issued a request for quotation for time servers. Beijing Zhongxin Chuang Co., Ltd. proactively collaborated to develop a detailed proposal and recommended its self‑developed and manufactured DNTS‑8 time server as the bid‑winning product. Following a highly competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, securing the contract for the Macao Transport Affairs Bureau’s Beidou timing equipment project.

The Transport Bureau of the Macao Special Administrative Region of the People’s Republic of China is an entity that participates in the People’s Republic of China. Government of the Macao Special Administrative Region Formulate, implement, and evaluate policies for the land transport sector, and delineate responsibilities. Continuously plan, promote, and assess the development of the land transport system, ensuring coordination and seamless integration with other modes of transport; conduct extensive research and introduce innovative solutions in the field of land transport, particularly intelligent transportation systems; undertake studies on traffic management and recommend necessary measures to ensure the safety and smooth flow of vehicular and pedestrian traffic. 。

Macao Transport Affairs Bureau Developed independently by Zhongxin Chuang DNTS-8 Time server The in-depth evaluation yielded results that exceeded the specified performance parameters, and we were highly satisfied with both our product quality and after-sales service. Procurement proceeded smoothly, and the products have now been put into operation.

The DNTS-8 network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an intelligent, high-precision NTP network time server. The DNTS-8 obtains standard time information from the GPS navigation and positioning satellite system and provides standard time services over the network via NTP/SNTP or other network protocols. Devices on the network that require time synchronization—such as personal computers, servers, and controllers—can synchronize with international standard time. When using a GNSS satellite receiver, users can define priority levels and configure single-receiver/dual-receiver or single-antenna/dual-antenna setups; each receiver can be set to operate in standalone or combined timing modes. If both receivers and other available time sources lose signal, the DNTS-8 relies on its built-in temperature-compensated crystal oscillator to maintain accurate timekeeping and continuously provide time services to external devices.

In addition to serving as a primary‑level network time‑synchronization device, the DNTS‑8 can also function as a secondary‑level time server, enabling more effective time synchronization in large‑scale network environments. It provides precise standard time signals for systems such as distributed networks, computer security systems, file management systems, e‑commerce platforms, online B2B systems, and cloud database storage and maintenance. The DNTS‑8 has been successfully deployed across government, finance, mobile telecommunications, public security, petroleum, power, transportation, industrial, and defense sectors. Installation and operation of the DNTS‑8HG network time server are exceptionally straightforward: simply connect the satellite receiving antenna and link the Ethernet port to a network switch to achieve time synchronization across all devices on the network.

◆GNSS satellite reference clock, with a built-in temperature-compensated crystal oscillator or rubidium atomic clock, serving as a stratum‑1 network time server.

◆ High throughput enables simultaneous synchronization of the clocks of tens of thousands of clients, servers, workstations, and other devices.

◆Optional 12-port 10/100M Ethernet, facilitating network configuration and deployment, and enabling easy system upgrades.

◆ Supports management via SSH, Telnet, Web, SNMP, and DNTS-Manager, enabling easy remote network login, administration, configuration, and maintenance.

◆ A single device with multiple network interfaces, or multiple devices with multiple network interfaces, can be configured to use the same IP address for hot backup.

◆ High reliability, with an MTBF of 90,000 hours

◆ Supports heartbeat detection and hot switchover across multiple devices and network interfaces.
