Abstract: PROBLEM TO BE SOLVED: To provide a method for automatically monitoring the trunk a communication system without needing any operator and without interrupting service to the user of the trunk by installing a means for deciding the next trunk to be tested in accordance with a trunk selection algorithm. SOLUTION: The trunk to be tested is selected by a processor 124 or an exchange 118. The processor 124 uses a selection algorithm for selecting the trunk to be tested. The exchange 118 selects the trunk which is directly connected to all the trunks of all user communication links and is decided from a list or from a prescribed trunk order. The trunk of a communication system can periodically or non-periodically and automatically be monitored without using an operator and without interrupting service to the user of the trunk.
