    摘要： Even if a signal line is momentarily disconnected while data communication, such as image data communication, is being performed by using, for example, an ITU-T Recommendation V.34 modem, communication is suitably continued. A main controller (CPU) determines the operating state (status) of a modem having the following mode. In this mode, the receiving operation of an image signal is automatically shifted to control signal communication upon detecting a pattern of a training signal. The main controller enables the above mode if it determines that the receiving status of the modem is not normal. It is thus possible for the modem to shift from the receiving of an image signal to control signal communication when the signal line is momentarily disconnected.

    摘要翻译： 即使通过使用例如ITU-T V.34建议书V.34调制解调器来执行诸如图像数据通信的数据通信时，信号线被短暂地断开，通信也适当地继续。 主控制器（CPU）确定具有以下模式的调制解调器的操作状态（状态）。 在该模式中，当检测到训练信号的模式时，图像信号的接收操作被自动移位以控制信号通信。 如果主控制器确定调制解调器的接收状态不正常，则启用上述模式。 因此，当信号线暂时断开时，调制解调器可以从图像信号的接收转移到控制信号通信。

    摘要： A communication apparatus and method is arranged such that, when executing a communication protocol conforming to V.34 recommendation, the communication procedure is appropriately recovered even if a second tone signal (a tone A or a tone B) is not received within 2 seconds. A CPU (central processing unit) recognizes a state of execution of the communication procedure by a modem. When the second tone A signal (or tone B signal) has not been received, the CPU causes the modem to receive the tone A signal for a defined time period. When the tone A signal has been received within the defined time period, the CPU returns the communication procedure conforming to the V.34 recommendation by the modem to the first half portion of phase 2.
