    • A telephone apparatus is disclosed wherein the use of the call-waiting service is provided while a dedicated call-waiting operating portion is not required. When there is a call from a third party's telephone apparatus to a first party while the first party is conducting a telephone conversation with a second party, a call-waiting unit switches the first party's line connection from the second party's telephone apparatus to the third party's telephone apparatus. A call-waiting operating portion or button is used to instruct the call-waiting unit to switch the line connection. The call-waiting operating portion is structured so that the operating portion can also be used as an operating portion that has a function other than the call-waiting function. When the call-waiting button is depressed, a CPU determines whether the line is connected and then whether the telephone apparatus is in a dialing or communication mode. Only in a case where the apparatus is in a dialing or communication mode, does the call-waiting button function. In the other cases, the CPU causes the call-waiting button to function as a function button that is normally not used during telephone conversation. For example, the call-waiting button may function as an abbreviated-dialing button, thereby reducing the number of required buttons or component parts, and thus, reduce production costs.
    • 公开了一种电话设备,其中在不需要专用呼叫等待操作部分时提供呼叫等待服务的使用。 当第一方与第二方进行电话通话时,当从第三方的电话设备到第一方的呼叫时,呼叫等待单元将第一方的线路连接从第二方的电话设备切换到第三方的电话 电话机 呼叫等待操作部分或按钮用于指示呼叫等待单元切换线路连接。 呼叫等待操作部分被构造成使得操作部分也可以用作具有除呼叫等待功能之外的功能的操作部分。 当按下呼叫等待按钮时,CPU确定线路是否连接,然后确定电话设备是否处于拨号或通信模式。 仅在设备处于拨号或通信模式的情况下,呼叫等待按钮是否起作用。 在其他情况下,CPU使呼叫等待按钮用作通话期间通常不使用的功能按钮。 例如,呼叫等待按钮可以用作缩位按钮,从而减少所需按钮或组件的数量,从而降低生产成本。
