摘要

Seizable, connection-associated switching devices of various types emit processing requests with different urgency degrees to a central sequential logic system for information which are to be processed with different urgency dependent on type. A limit value which may be set in an occupation rejection device based on the measure of a continuously-measured, momentary sequential logic system load serves as a comparison normal and effects that processing requests are rejected (accepted) when the urgency value is lower than (greater than) the limit value. In accordance with the constant, type-associated residual acceptance value stored in the request rejection device for each of the various types of processing requests, a respective rejection character is assigned in cyclical succession to a plurality of processing requests corresponding in number to a respective cycle via the urgency value of the respective processing requests of the appertaining type when the critical limit value is exceeded, being respectively assigned to all but one of these processing requests, whereby this one processing request has an acceptance character assigned thereto.
