Zhongxin Chuangwei provides a time synchronization server to Shijiazhuang Tiedao University.

Recently, Shijiazhuang Railway University Co., Ltd. issued a request for time servers. Beijing Zhongxin Chuang Company responded proactively by preparing a detailed proposal for the client and recommending products independently developed and manufactured by Zhongxin Chuang. The DNTS‑8 time server, the product submitted for this tender, emerged victorious after a fiercely competitive bidding process. Thanks to its high quality and comprehensive after-sales service, Zhongxin Chuang outperformed competitors’ offerings and was ultimately awarded the time server project from Shijiazhuang Railway University Co., Ltd.

Shijiazhuang Tiedao University ( Shijiazhuang Tiedao University, abbreviated as “Tieda” [37] “Shi Tie Da,” located at Hebei Province Shijiazhuang City ， Hebei Provincial People’s Government and Ministry of Education of the People’s Republic of China 、 National Defense Science and Technology Industry Bureau 、 National Railway Administration Jointly built by all four parties National Key Universities , selected “ 2011 Plan ”, “ Project for Enhancing the Basic Capabilities of Universities in Central and Western China ”、 National Undergraduate Innovation and Entrepreneurship Training Program 、 National-Level New Engineering Research and Practice Project 、 “ Outstanding Engineer Education and Training Program ”。

Shijiazhuang Tiedao University Co., Ltd. Developed independently by Zhongxin Chuang DNTS-8 Time Server Conduct an in-depth evaluation and arrive at the final results. All are superior to the parameter requirements. ， And also 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 acquires 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.
