摘要: 針對傳統(tǒng)的交叉連接設(shè)備在進行通路測試時的缺點,作者提出了一種新設(shè)計方案,用戶可以不購買專門的測試設(shè)備而利用交叉連接設(shè)備本身的功能就能進行交叉連接通路的測試。故方便了用戶,也節(jié)省了投資,而交叉連接設(shè)備的復(fù)雜性并沒有太大的增加。這種在系統(tǒng)內(nèi)部包含自動測試功能的想法,對于加速系統(tǒng)的開發(fā)調(diào)試和生產(chǎn)中的產(chǎn)品檢驗都有較大的意義。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.
