Abstract

PURPOSE:To simplify the constitution of a control circuit and also to facilitate the addition and modification of functions, by decentralizing the connection processing of a switchboard and that of a console panel with regard to a hotel control circuit. CONSTITUTION:The central control circuit of automatic switch-board 1 and hotel control circuit 3 are connected together via interface circuit 2, and control circuit 3 and hotel console panel 5 via hotel console panel interface circuit 4. This console panel 5 is provided with printer control circuit 51 for cotrol over printer 6. Control circuit 3, on the other hand, is provided with the program memory, temporary memory, clocking circuit, processor. Through the data transfer bus in control circuit 3, the central control circuit of the switchboard is connected to console panel 5. This connection processing decentralized by the processor and respective memories in control circuit 3 as the connection processing under the central control and that by console panel 5.
