Abstract

A circuit arrangement for telecommunications exchange systems, particularly telepone exchange systems, comprising information processing sequential logic systems and traffic measuring devices, is provided for handling processing requests. Processing requests are marked by a sequential logic systems as partially acceptable and input into a waiting list formed as a FIFO buffer. Processing requests marked not acceptable are input into a FIFO-LIFO memory which ejects a processing request in a FIFO mode when it is full and when the waiting list is at least partially filled and marks them as not acceptable, but marks processing requests as acceptable and outputs the same to the waiting list in the LIFO mode when the waiting list is empty or nearly empty.
