ABSTRACT:
An arrangement for detecting defective communications circuits in a telecommunications system. Communications circuits are arranged in groups according to destination. Unacknowledged communications are counted for each group. A group whose incidence of such unacknowledged communications is especially high is likely to contain one or more defective communication circuits. More detailed measurements, including a count of attempts to use each member of such a group, are then taken to identify individual defective communication circuits. A communication circuit having an especially high count of attempts to use is likely to be defective.
