研制程控交换机是我国目前通信科研中的主要项目之一。诊断维护程序是交换机软件的重要组成部分,虽然引进的程控交换机一般都带有诊断维护程序,但这些程序都是针对具体机器设计的,而设计思想则属厂家机密。因此,要研制程控交换机,在诊断测试方面也有不少工作要做。本文对该项目中的一个不可缺少的技术课题——用户级控制系统的诊断测试进行了研究,主要做了以下三个方面的工作:
The development of program-controlled switches is one of the major projects in China’s current communications research. Diagnostic maintenance program is an important part of the switch software, although the introduction of program-controlled switches are usually equipped with diagnostic maintenance procedures, but these programs are designed for specific machines, and the design ideas are factory secrets. Therefore, to develop program-controlled switches, there are a lot of work to do in diagnostic tests. In this paper, an indispensable technical project in this project - the user-level control system diagnostic test was studied, the following three aspects are mainly done:
