Zhongxin Chuang has provided clock synchronization equipment to China Railway Urumqi Bureau Group Co., Ltd.

Recently ， China Railway Urumqi Bureau Group Co., Ltd. issued a requirement for a time server. Beijing Zhongxin Chuang Company responded proactively by preparing a detailed proposal for the customer and recommending its own independently developed and manufactured product. The DNTS‑8 time server, as the product being bid for in this round, underwent a fiercely competitive bidding process. Zhongxin Chuang, with its high‑quality products and comprehensive after‑sales service, emerged victorious over its competitors. The manufacturer’s products stand out. And As a result, it ultimately won the Time Server Project of China Railway Urumqi Bureau Group Co., Ltd.

China Railway Urumqi Bureau Group Co., Ltd. is managed by China State Railway Group Co., Ltd. One of the 18 railway bureau group companies, abbreviated as “Wu Bureau.” It is located in a multi-ethnic region on the northwestern frontier and lies at the far periphery of the national railway network.

China Railway Urumqi Bureau Group 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 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 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.
