摘要
2M是采用子速率复用技术的DDN专线入网方式,本文首先提出了一个将2M线路的31个时隙里包含的串口数据透明转换为31路Winsock进行传输的组网方案,然后说明了基于工业PC的通信前置机系统硬件组成和多串口与网口的数据转换软件设计思想。
M is a mode of accessing network by using velocity multiplex division technology.In this paper,the scheme of transforming between 31 timeslots in a single 2M line and 31serial ports is introduced.The hardware and software design of data transfer base on industrial PC is described.
