PURPOSE:To attain data transmission with a master set by adding a present set identification code to a data stored in a storage means, sending the result in a radio wave, receiving the radio wave including present set identification code and storing the received data into the storage means. CONSTITUTION:Present identification signal, a destination identification signal and a data entered from a keyboard 11 to a modulator 18 are modulated into a transmission data signal, radiated externally from an antenna 19 and are received at a base station for a radio telephone set and sent to a master set connected via a communication wired line. The master set adds an identification signal for a destination portable equipment to a data to be sent and sends the resulting data and the data radiates externally from the base station. A portable terminal equipment receives the electromagnetic wave at its antenna 19, the reception data signal composed of the data and the destination identification code demodulated by a demodulator 20 is inputted to computing element 15. The computing element 15 confirms whether or not the destination identification code points out its own equipment. When the destination identification code is addressed to present equipment, the data is stored in a memory 12 and the mode restores to the entry by the keyboard 11. |
