摘要: 针对传统的交叉连接设备在进行通路测试时的缺点,作者提出了一种新设计方案,用户可以不购买专门的测试设备而利用交叉连接设备本身的功能就能进行交叉连接通路的测试。故方便了用户,也节省了投资,而交叉连接设备的复杂性并没有太大的增加。这种在系统内部包含自动测试功能的想法,对于加速系统的开发调试和生产中的产品检验都有较大的意义。Abstract: One novel method of Self-Test is proposed in this paper to avoid the shortcomings of the traditional testing ways for digital cross-connect systems. By implementing the self-test functions in the system, the established connect can be easily tested with no need for special testing equipment. This can greatly ease the test of connect and system and save the investment with only a little increment of systems complexity. The idea to contain the self-test function in the system would be very helpful for accelerating the development of system and also for the verifying of the products.
