时分接线器(T接线器)是数字程控交换机等中换网络的核心部件之一,如何对它进行自动测试是国内研制数字程控交换机急待解决的一个课题。本文对这一问题进行了研究,作了以下几项工作: 一、提出了一种基于功能块的T接线器测试算法作者将T接线器表示成功能块的形式(见论文图1-2),并将T接线器划分成图1所示的五个模块。在此基础上,先分别导出这五个模块的测试,再导出整个T接线器的测试。
Time switch (T switch) is the digital program-controlled switches and other network components to change one of the core, how to test it automatically is the development of digital program-controlled switches urgently need to solve a problem. This paper has carried on the research to this question, has made the following several works: First, proposed a based on the function block the T switch test algorithm author T connector said that the successful function block form (see the paper Fig. 1-2) , And divide the T switch into five modules as shown in FIG. 1. On this basis, the first five were derived from the test module, and then export the entire test T switch.
