Abstract

1. Circuit arrangement for telecommunication exchanges, in particular telephone exchanges, with centralized and decentralized information-processing switching devices, which have a limited capability with regard to the information-processing capacity, and with a centralized switching matrix (K), and with decentralized line trunk groups (LTG), to which in each case a decentralized switching device is assigned, and to which subscriber lines, connecting lines, for example local and long-distance junction lines, and connection-individual switching facilities, for examples connector sets and selection receiving facilities, are connected, and which conduct an exchange of data, for example of selection information and control and setting information, with the central switching device, this exchange serving the execution of the individual switching operations, and with measuring facilities for determining when there is a discrepancy between the acute information-processing workload of a centralized switching device and its capability, in particular for detecting information-processing traffic overloads and for averting such overloads, and with rejection facilities which are assigned to the decentralized line trunk groups and in which the quantity of information-processing orders occurring is reduced by a certain percentage of these orders being rejected, and with transfer switching means for the signalling of data on the discrepancy between the acute information-processing workload and the capability of a centralized switching device to the decentralized switching devices, in which the percentage is stored and in which memory switching means, provided for the storage of this percentage, reduce or increase the stored percentage step by step whenever data signalling an increase or decrease arrive, the data serving to signal the increase or decrease of this percentage being transferred from the centralized switching device to the decentralized switching devies and in the latter to the memory switching means, together with the data transferring the execution of the switching operations from the centralized switching device to the decentralized switching devices, in particular the setting and control information, characterized in that the data serving to signal the changing of the percentage and to transfer in each case from the centralized switching device to a decentralized switching device are passed on when connections are established via the switching matrix (K) and via two of the connection-individual switching facilities, which are connected to various line trunk groups, together with switching identifier information, in particular transit information, to be transferred connection-individually and from connection-individual switching facility to connection-individual switching facility and, thereby transmitted from the decentralized switching device just mentioned to the other decentralized switching devices.
