The DMCS-1 is a fully digital mobile communications system developed by China Electronics Technology Group Corporation (CETC). The system provides both wired and wireless voice and data communications for ground troops. The transmissions and encryption are fully digitised to achieve better performance and security.

DMCS-1是一种由中国电子科技集团公司（CETC）发展的全数字式移动通信系统。系统为地面部队提供连线和无线两者语音和数据通信。传送和加密完全数字化达到较好的性能和安全。

The system provides 12 frequency channels to form a radio communication network, in which both wired and mobile users can use voice/data transmission services simultaneously. The maximum transmission radius is 15km. The system has a transmission speed of 1,200~2,400bps. The system can also be connected to a local telephone network via analogue relays. Users can get access to the PTSN by the secondary dialling. When the system is used as a sub-system of a global network, its users can also become direct dialling users of the global network.

系统提供12个频道去构成一个无线电通信网络，连线和移动使用者能同时使用语音/数据传送服务。最大传送半径15公里。系统传输速度1,200~2,400 bps。系统也能经由模拟中继连接到一个当地电话网络。使用者通过代理拨号能访问“软交换网络窄带业务”（PTSN）。当系统被当作全球网络一个子系统使用的时候，它的使用者也能成为全球网络的直接拨号用户。
