Recently, CITIC Central Hospital has deployed a time server. of the Demand , Beijing Zhongxin Chuang Company is actively cooperating. For users A detailed plan has been prepared, and the independently developed and manufactured products of Zhongxin Chuang have been recommended. Type DNTS-8 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 the CITIC Central Hospital’s Synchronous Server Project.

Zhongxin Central Hospital is located on the western section of Jinghua Road, Jianxi District, Luoyang City, Henan Province, and covers an area of… With a site area of 11,000 square meters and a total floor space of 46,000 square meters, the hospital was founded in 1956. It is a national general hospital integrating medical care, preventive services, rehabilitation, occupational disease prevention and control, scientific research, and education. It also serves as a designated hospital for the New Rural Cooperative Medical Scheme and for supplementary medical assistance (insurance) programs for urban and rural residents in financial need.

CITIC Central Hospital To China–Singapore Innovation Independently developed 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. DNTS-8 A time server is a high-tech, intelligent device that can operate independently and is based on… High-precision clock synchronization server compliant with the NTP/SNTP protocol. DNTS-8 The time server from Standard clock signal information is obtained from GPS or BeiDou geostationary satellites and transmitted over the network, enabling devices that require time synchronization—such as computers and controllers—to align with the standard clock. When both GPS and BeiDou receivers are in use, a priority can be configured; by default, BeiDou takes precedence, with GPS serving as a backup. If neither receiver receives a signal, the DNTS‑8 relies on its built-in temperature‑compensated crystal oscillator for holdover, achieving a holdover accuracy of up to 1 × 10⁻⁹. DNTS-8 Using standard clock information via TCP/IP network transmission: DNTS-8 supports multiple popular time‑broadcast protocols, such as NTP and time/UDP, and also accommodates Sinotech‑defined time‑broadcast packets on 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. DNTS-8 Also supports The broadcast operating mode of the SNTP protocol.
