Abstract

A coupling fault diagnosis procedure is proposed for digital switching networks constructed of uniform time-division switches. The procedure is executed in two phases. Each phase consists of eight test steps; the number of tests for detecting the most likely coupling faults inside a single switch is independent of the network size. The concept of primitive and convolutional test vectors is introduced in order to analyze test stimuli applied to successive switches during the test. The approach can be easily adapted for use in many modern digital exchanges
