摘要
Method and means for controlling digital message information through a switching network, which has at least partially duplicated equipment (DDM-A, DDM-B) enabling the establishment of at least partially duplicated transmission paths and transmission of message information with fault control via each of the duplicated transmission paths. In a method in accordance with the invention the read addresses for a speech store (SS) are also controlled for each transmission path and in a similar way as control of the message information. In detection of an error in a read address the read-out information is transmitted together with fault control result information indicating that a fault affecting this message information has been detected. A switching network in accordance with the invention has control means (CH) and information selection means (PS) for this purpose.
