Abstract: PURPOSE:To attain quick data communication by sending constitution section addition information identifying each constitution section via a communication line together with data information so as to relieve the operating load of a control section. CONSTITUTION:The constitution section additional information 25 is added to a format of a data signal sent/received between a communication terminal equipment 8 and a center 7. In the case of constitution section additional infor mation 'A', a display part or a data input part is represented, and in the case of information 'B', a data recording part is expressed and in the case of infor mation 'C', a control section is expressed. Thus, in the case of the reception, the data signal is shared by destination of the data information only with the additional information and in the case of transmission, at which constitution part the data information of the signal is generated is recognized quickly by the center side.
