The Evolution of Digital Cross-Connect System(DCSS) 数字交叉连接(DXC)系统的演变
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 he easily tested with no need for special testing equipment. 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。
