摘要： A cordless telephone consisting of base and handset units is disclosed wherein a control circuit incorporated in the base unit comprises first and second D/A converters, first and second A/D converters, and first and second sync. signal generation circuits. The first and second D/A converters respectively convert digital signals from the handset unit and a PBX. The first and second A/D converters convert the analog signals provided from the first and second D/A converters to transmit them to the PBX and handset unit, respectively. The first sync. signal generation circuit regenerates a first clock signal synchronously with a sync. signal provided from the PBX to render the first A/D and second D/A converters to operate in synchronism with the sync. signal from the PBX. The second sync. signal generation circuit generates a second clock signal which is independent of the sync. signal from the PBX to render the first D/A and second A/D converters to operate in synchronism with the second clock signal. Accordingly, the synchronization between the base and handset units is effected independently of the synchronization signal from the PBX.

摘要： Provided is a multi-wireless connection device that point-to-multipoint connects a communication link between a plurality of cellular phones to be connected to a cellular network, and a cordless phone that remote controls an outgoing call from the plurality of cellular phones to the cellular network or an incoming call from the cellular network to the plurality of cellular phones. The multi-wireless connection device maintains the synchronization within the Bluetooth network and performs point-to-multipoint connection by transmitting and receiving control data between the plurality of cellular phones via an ACL link.

摘要： The cordless telephone system according to the present invention comprises a synchronization inhibiting circuitry for inhibiting, when a calling station sends a communication end request code, synchronization with a called station in communication therewith for a prespecified inhibit time after transmission of the communication end request code, and a communication terminating circuitry for terminating communication if a state where synchronism with the called station is lost continues for a prespecified reference time during communication. Thus, communication is terminated without fail when a call ends, and transactions of unnecessary electric waves are reduced.

摘要： A cordless telephone set comprises a base unit and a handset unit connected by a radio frequency (RF) link which is established by digital burst data transmission and is synchronized by a unique word which is included in the digital burst data. The radio transmission signal is not continuous and it requires the synchronization. The unique word is detected by the unique word detecting means and is used to establish the burst data synchronization. The unite word consists of frequency channel information and fixed unite data. By using this information, the base unit and the handset unit are prevented from trying to establish a radio link at incorrect frequency when a spurious signal, not intended for the base unit and/or handset unit is erroneously received.
