Circuit arrangement for avoiding overload in a broadband switching system

Abstract

Abstract To avoid overload in a broadband switching system, in which the message is divided into blocks and transmitted via broadband transmission paths using an asynchronous time-division multiplexing method, it is known for bi-directional counters (VRZ) which are allocated to the different users to be disposed in the switching nodes (VK). By referring to the counter reading of the bi-directional counter it is possible to check in simple fashion that the maximum and mean transmission speeds, which can be pre-defined by the user terminal (T), are maintained. <??>To avoid overload and to register call charges, two forward counters (Z1, Z2) are in each case allocated in the switching node to each user terminal instead of a bi-directional counter. This allows both the call duration and the blocks transmitted during the call duration to be registered. An overload detection criterion is derived from the relationship between the counter readings. <IMAGE>
