One novel impleemntation of digital cross connect system with self-test
一种具有自动测试功能的交叉连接设备的新方案

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. This can greatly ease the test of connect and system and save the investment with only a little increment of system's complexity. The idea to contain the self-test function in the system would he very helpful for accelerating the development of system and also for the verifying of the products.
