发明名称 CONNECTOR FOR DIGITAL CORDLESS TELEPHONE SYSTEM
摘要 PROBLEM TO BE SOLVED: To obtain the connector whose connection number to the digital cordless telephone system is increased through the adoption of a distribution processing system. SOLUTION: The digital cordless telephone system is provided with plurality of connectors connecting to an extension bus from a master set such as a home telephone set and plurality of slave sets connecting to the connectors through radio channels adopting the TDMA/TDD system. In this case, each connector for the digital cordless telephone system is provided with a means that generates a reference clock and a reference timing from outgoing bus data from the master set through the extension buses and with a means that individually sets a time width from a reference point of time of the reference timing till its own transmission reception slot so that slots used by the respective connectors are not timely overlapped. Furthermore, in the case that the connectors whose number is more than number of transmission reception slots connect to the master set above, carrier sense is conducted and different transmission frequencies are used as required.
