Congratulations to Jiangxi Copper Corporation Limited on procuring the Zhongxin Chuang time synchronization equipment.

 

 

 

Recently, Jiangxi Copper Corporation Limited Published Time server The procurement announcement, with Beijing Zhongxin Chuang Company actively cooperating. For users A detailed plan has been prepared, and products independently developed and manufactured by Zhongxin Chuang have been recommended. DNTS-8 series Type As the product submitted for this tender, Zhongxin Chuang stood out by defeating competitors’ offerings thanks to its high‑quality products and comprehensive after‑sales service, ultimately… Awarded by Jiangxi Copper Corporation Limited Time server Project

Jiangxi Copper Corporation Limited was established in In 1979, the company shouldered the nation’s noble mission of “overcoming the backward state of China’s copper industry and revitalizing it.” Over the past four decades, benefiting from the country’s sustained economic growth and driven by its own expertise and unwavering focus, it has grown into a major producer of cathode copper in China and a comprehensive supplier of a wide range of copper‑processing products.

Jiangxi Copper Corporation Limited To China–Singapore Innovation Independently developed DNTS-8 Time server Conduct an in-depth evaluation and arrive at the final results. All Exceeds the parameter requirements And Regarding our company’s product quality and after-sales service Also quite satisfied. Procured successfully and put into use.

Developed by Beijing Zhongxinchuang Technology Co., Ltd. The DNTS‑8 time server is a high‑tech, intelligent, stand‑alone clock synchronization server that operates on the NTP/SNTP protocols and delivers high‑precision time. It obtains standard time‑signal data from GPS satellites and disseminates this information across the network, enabling devices requiring precise timing—such as computers and controllers—to synchronize with the reference clock. When all external signals are unavailable, the DNTS‑8 relies on its built‑in temperature‑compensated crystal oscillator for holdover, achieving a holdover accuracy of up to 1 × 10⁻⁹. The DNTS‑8 transmits standard time information over TCP/IP networks and supports multiple popular time‑distribution protocols, including NTP and time/UDP; it also accommodates custom‑defined time‑broadcast packets via configurable UDP ports. The port numbers for NTP and time/UDP are fixed at 123 and 37, respectively, as specified in RFC‑123 and RFC‑37. Additionally, the DNTS‑8 supports the broadcast mode of the SNTP protocol.
