Zhongxin Chuangwei provides a clock synchronization server to Beijing Traditional Chinese Medicine Hospital.

Recently, Beijing Traditional Chinese Medicine Hospital issued a request for a time server. Beijing Zhongxin Chuang Company promptly collaborated to develop a detailed proposal and recommended its independently developed and manufactured DNTS‑6 model as the bid‑winning product. Following a fiercely competitive bidding process, Zhongxin Chuang stood out thanks to its high‑quality products and comprehensive after‑sales service, ultimately securing the contract for the Beijing Traditional Chinese Medicine Hospital’s time‑synchronization server project.

The Beijing Hospital of Traditional Chinese Medicine, affiliated with Capital Medical University, was founded in 1956 and is located at Nos. 23 and 61, Meishuguan Houjie, Dongcheng District, Beijing. It is a Grade III Class A TCM hospital that integrates medical care, education, scientific research, disease prevention, and health maintenance.

Beijing Traditional Chinese Medicine Hospital conducted an in-depth evaluation of the DNTS-6 time server, independently developed by Zhongxin Chuang. The results consistently exceeded the specified performance parameters, and the hospital expressed high satisfaction with both the product’s quality and our after-sales service, leading to a successful procurement and deployment.

The DNTS-6 network time server, developed by Beijing Zhongxinchuang Technology Co., Ltd., is an intelligent, high-precision NTP network time server. The DNTS-6 obtains standard time information from systems such as GPS, BeiDou, GLONASS, Galileo, 4G, and CDMA, and provides standard time services over the network via NTP/SNTP or other network protocols. Devices in the network that require time synchronization—such as personal computers, servers, and controllers—can synchronize with international standard time. Additionally, when using GNSS satellite receivers, priority can be configured, supporting single-receiver/dual-receiver and single-antenna/dual-antenna setups; each receiver can be set to timing mode individually or in combination.

The DNTS-6 features one or two 10/100 adaptive Ethernet ports, which are physically isolated from each other to ensure data security. These ports can be configured either on the same network segment or on different segments, providing redundancy: a failure in one port will not affect the normal operation of the others. Each Ethernet port must be assigned an independent IP address.
