    • In an apparatus that has a main power supply and a sub-power supply and that halts a main power supply in the standby state, the main power supply is turned on for an incoming call for facsimile communication, while the main power supply is not turned on for an incoming call for speech communication. Therefore, the unnecessary turning on and off of the main power supply can be prevented. When the DRPD (Distinguish Ringing Pattern Detect) service is provided, a plurality of telephone numbers are assigned to a single communication line, and a plurality of call signals whose pattern differ are employed for receiving calls. When one of these telephone numbers is used for facsimile and another telephone number is used for a telephone, an incoming call can be identified as being either for facsimile or for telephone by distinguishing between the patterns of the call signals. When the pattern of the call signal is for facsimile, the main power supply is turned on to perform data communication. When the pattern of the call signal is for telephone, the main power supply is not turned on.
    • 在具有主电源和副电源并且在待机状态下使主电源停止的装置中,主电源在用于传真通信的来电时打开,而主电源未被打开 接通语音通信的来电。 因此,可以防止主电源不必要的打开和关闭。 当提供DRPD(区分振铃模式检测)服务时,多个电话号码被分配给单个通信线路,并且多个呼叫信号的模式不同被用于接收呼叫。 当这些电话号码中的一个用于传真而另一个电话号码用于电话时,可以通过区分呼叫信号的模式来将来电识别为传真或电话。 当呼叫信号的模式用于传真时,主电源打开以执行数据通信。 当呼叫信号的模式用于电话时,主电源未打开。
