Abstract: The overload control uses monitoring of the speech processing delay at defined time intervals, with a priority which is less than the speech processing priority, to initiate an overload control procedure with a higher priority than the speech processing priority in dependence on the monitored processing delay. When the central processing unit occupation level does not fall below a defined reference value within a second defined time interval, an overload condition is indicated, with the decentralised processors of lower order informed of the overload.

Abstract: The method controls overloading in a fully electronic exchange system including and operating and a waiting processor which indicates a cut off and makes an interface available to a user. It also has a number translation processor, an internal network processor which connects different floors, and several access processors. The latter are arranged to be distributed about the other processors. An overload control is started by the user, using a release value for the original calls, a value for the incoming calls and a value for the target and outgoing calls, for calls from the user which are accepted over a first period. A delay in each processor in the priority sequence is detected and used to determine a system overload. A CPU busy rate of each processor is determined in a second period and used to determine a traffic overload of a processor. The control procedure used depends on the type of overload, i.e. either a user overload, a system overload or a traffic overload.

Abstract: The method controls the overloading of distributed access switching processors in a fully electric exchange system, in which the subscriber and official lines are arranged in a distributed manner. Thus access for calls and setting calls is carried out also in a distributed manner. First, monitoring is carried out of the call processing delay which is loaded into an access processor in accordance with a priority which is not higher than the call processing process but is higher than an operating and waiting process. The overload process is carried out according to a priority higher than the processing process where an overload in an access processor is determined and controlled. A process of varying a CPU reference value is continually repeated when a request is made by a user. After this the monitoring and overload control methods are started.
