| Abstract: | The Subscriber Line Circuit(SLC)board in SPC switching system is a hybrid-circuit board that contains digital and analog circuits.It is very difficult in testing and diagnosing faults by traditional methods.A functional test method based on units is proposed.In the paper,the test and diagnosis strategy,method of partition the board into units and algorithm of generating optimum diagnosis tree for the analog circuit part are also given. |
