ActiveInformation technology - Telecommunication and information exchange between systems - DTE to DTE direct connections
信息技术 系统间远程通信和信息交换 DTE到DTE直接连接
Application Summary AI generated
This standard specifies the electrical, mechanical, and functional interface characteristics for direct data terminal equipment (DTE) to DTE connections without intermediate data circuit-terminating equipment (DCE). It is applied in information technology and telecommunications systems where two DTE devices, such as computers or terminals, need to communicate directly over short distances using serial interfaces like RS-232. The standard ensures interoperability in testing, industrial control, and data exchange contexts where a modem or other DCE is not required.
