An augmentation of a time-division switch is proposed so that this switch has an additional property of fault self-detection. Data patterns from normal operation (i.e. speech samples and control signals) serve as test patterns and a failure occurrence caused by some intermittent or solid fault can be detected by means of a built-in testing circuit
