PURPOSE:To eliminate the need for a construction cost and to attain quick call by providing plural telephone sets provided with a weak radio wave transmitter and plural reception slave sets provided with a control section and activating an annunciation section when a number of the weak radio wave receiver receiving a weak radio wave is coincident with the number assigned to itself. CONSTITUTION:The subject telephone system consists of plural telephone sets 31-3m provided with a weak radio wave transmitter 33 and plural receiver slave sets 41-4n provided with a control section 42 activating the annunciation section 43 when the number of a weak radio wave receiver 41 receiving a weak radio wave sent from a weak radio wave transmitter 33 is coincident with the number assigned to itself. Since the dial signal of the dialed number is sent from the weak radio transmitter to the plural receiver slave sets, the plural receiver slave sets 41-4n receive a dial by the weak radio wave receiver and the called party can reply from the telephone set in the vicinity. Thus, no construction cost is required and the called party is quickly called. |
