摘要： A radio communication system of a multi-channel access type in which an idle one of a plurality of radio channels is detected to perform transmission and reception of voice signals, data signals or the like. In the present system, in the case where a base unit receives an incoming call from a wired line, the base unit transmits to a plurality of radio terminal units a speech channel designation signal as well as a representative radio terminal designation signal specifying a representative radio terminal unit from the plurality of radio terminal units, and when receiving a channel switching completion signal from the representative radio terminal unit, the base unit transmits a signal for generation of ringing tones to the plurality of radio terminal units at the same time to cause the plurality of radio terminal units to generate the ringing tones at the same time.

摘要： Disclosed is a radio channel control method for a system including a main apparatus connected to a telephone line and having a channel control function, a plurality of stationary apparatuses connected to the main apparatus and each having a radio transmitter/receiver, and a portable telephone capable of communicating with the stationary apparatuses through a radio channel. In this method, the main apparatus designates each stationary apparatus in a main or sub state to control communication with the portable telephone and monitors a state signal including information of the main or sub state transmitted from each stationary apparatus. When the state signal from a given stationary apparatus does not coincide with a state of the given stationary apparatus designated by the main apparatus, the main apparatus transmits a state designation signal to the given stationary apparatus to coincide with the state designated by the main apparatus.

摘要： A control method for a cordless telephone system including a main apparatus connected to a telephone line and having a line control function, a plurality of stationary apparatuses connected to the main apparatus and each having a radio transmitter/receiver, and portable telephones capable of communicating with the stationary apparatuses through a radio channel. When the main apparatus receives a simultaneous calling request signal from one portable telephone through a given stationary apparatus, it transmits a simultaneous calling request signal to whichever of the other portable telephones are not in use through corresponding stationary apparatuses. The main apparatus then receives, from that responding portable telephone through the corresponding stationary apparatus, an incoming call response signal including an extension number of the responding portable telephone which received the simultaneous calling request signal, and transmits a response display signal including that extension number to the portable telephone which requested simultaneous calling. The portable telephone which requested simultaneous calling displays the extension number of the responding portable telephone.

摘要： A cordless telephone system comprises a radio telephone set and a connection unit connected to a wire telephone circuit and also connected to the radio telephone set through a radio communication circuit, for interconnection control between the wire telephone circuit and the radio telephone set. When the wire telephone circuit is put in an unusable state or a signal on the radio communication circuit is put in an unreceivable state, the connection unit transmits a disconnecting signal to the wireless telephone set to forcibly cut off the radio communication circuit.

摘要： A cordless telephone having a base unit and a plurality of radio telephone sets. The base unit delivers a ringing signal from a telephone line to a radio telephone set which is in telephone communication with a remote subscriber coupled to the telephone network, and a receiving radio telephone set in accordance with a request for transfer by the transferring radio telephone set. If the receiving radio telephone set responds to the ringing signal and goes off-hook, the telephone communication is transferred to the receiving radio telephone set from the transferring radio telephone set. If the receiving radio telephone set does not respond or does not go off-hook, the transferring radio telephone set responds to the ringing signal and goes off-hook to carry on the telephone communication.
