Abstract
Abstract A program arrangement for a telephone system is disclosed in which operator position key action signals are rehoppered for a call whenever the signals are received by the base level processor during short real time breaks of a priorly initiated base level key action program that has not yet completed its work function for the same call. When the program takes a real time break of a significantly longer duration, such as queuing for an available facility, the rehoppered key signals and any newly arrived key signals for the same call are analyzed to determine whether they represent logical or illogical service requests. Illogical requests are disregarded. Logical requests are used to change the state or progress of the call.
