1. Circuit arrangement for telecommunication exchanges, especially telephone exchanges, with packet switching of messages from and to one of a plurality of message processing units via message channels (N), via which packets of messages originating from or to be fed to the said message processing unit and provided in each case with an individual destination address are transmitted, and with a transmission processor, which executes the transmission operations, which passes on the packets of messages on the basis of their respective destination address to and from the message channels and on the basis of routing data stored in it and related to a given message channel network configuration, as well as comprising routing rules, and which receives an amendment request signal for an amendment, in particular due to faults and/or fault suppression, with respect to the actual and/or use-related effective network configuration or for an amendment of routing rules and, according to a stored amendment scheme, issues corresponding commands for the message channels affected by such an amendment or by such amendment, characterized in that the transmission processor is provided in plurality for parallel operation (P1-P6), in that consequently at least two transmission processors operate in parallel, in that they handle their transmission procedures between the message channels on the one hand and the message processing unit concerned on the other hand independently of one another, and in that, when an amendment is to be made, an amendment request signal goes to all of the transmission processors, in that the latter all generate and issue the corresponding commands for the message channel concerned or the message channels concerned and in that a marking which designates one of the transmission processors, is stored at the message channels (V1-VP) or else-where and is transmitted to the message channels, causes the said transmission channels to execute from among the commands corresponding to the respective amendment and divised and issued by all of the transmission processors independently of one another those only of the transmission processor designated by the marking, but to ignore or reject those of the other transmission processors. |
