  • Patent number: 10135998
    Abstract: A key telephone system includes a terminal and a primary device. The primary device transmits a command for transition into a power-saving state to the terminal, together with a power-saving duration time datum and/or a power-saving deactivating time datum, when the time reaches a power-saving state transition time. The terminal specifies the power-saving duration time and/or the power-saving deactivating time in the timekeeper means, and halts the communication means for communicating with the primary device at the time of receiving the command for transition into the power-saving state from the primary device, and activates the communication means being halted at a time when the timekeeper means has measured the lapse of the power-saving duration time and/or the power-saving deactivating time.

  • Patent number: 9787833
    Abstract: In nurse call systems that enable communication from a plurality of cordless handsets with a plurality of extension terminals carried by nurses belonging to a group, a nurse call conversion unit is provided between a nurse call control device and a private branch exchange. A call signal for a group representative call in which only an identification number for a group is given is transmitted by the nurse call conversion unit from the nurse call control device to the private branch exchange. From this call signal, the private branch exchange generates a call signal for extension terminals belonging to a group and calls the extension terminals.
