SDH站点的交叉功能是实现业务配置和SDH网络保护倒换功能的基础，它联系起了支路信号和线路信号。首先通过对交叉架构的设计，使用软件仿真实现SDH站点中的交叉连接系统，完成SDH站点的交叉功能；其次，针对现网SDH站点的业务配置中，有时会出现内部阻塞的情形，该交叉仿真系统能对低阶交叉配置出现的内部阻塞问题进行模拟，以利于实际中的业务配置相关问题的分析与解决。为实现以上两个主要仿真功能，这里结合VC?12帧的特点，提出了一种基于改良TST结构的低阶交叉仿真部署方案CFTT。

The cross connection function of SDH station is the basis for service configuration and SDH network protection switching function. Due to the important role of the cross connection function in the SDH network,the cross connection architec?ture is designed in this paper and software simulation technology is used to achieve the cross connection function of SDH station. this cross connection simulation system is able to simulate the phenomenon of the inner obstruction which appears in the SDH low?order cross configuration sometimes. Therefore the simulation system can analyze and solve the problems of service configura?tion in reality. To achieve the above two major simulation functions,a low?order cross connection simulation program called CFTT(Connect First Test Then)based on the improved TST structure is proposed in combination with the characteristics of VC?12.
