Abstract

In a processor-controlled telecommunications exchange, to avoid overloading the computer the number of call attempts per unit time is checked at clock intervals and limited. A prediction unit assesses from the call distribution and the mix of call types the expected computer occupancy and on the basis of those predictions fixes the number of call attempts to be accepted. <IMAGE>
