Abstract

PURPOSE:To give plural functions to one key to extend service, by providing a means, which stores the precode corresponding to an advance operation, and a means which synthesizes the precode and the code, which discriminates the operation key, to discriminate the key operation purpose. CONSTITUTION:The operator of attendant board ATT depresses push-button ADi for the purpose of calling a specific office subscriber. Conversion push-button code adi is detected by scanner SCN and is transferred to central processing unit CC. Meanwhile, fundamental code P1 determined previously is stored in precode storage part KB in memory unit MM. Unit CC synthesizes code P1 and adi and analyzes them to start the trunk originating connection processing and the selection processing for the dial number which purposes selecting the specific office subscriber corresponding to push-button ADi.
