    • A facsimile communication system and a communication apparatus reduce a loss time due to the synchronization of transmission/reception and shorten a communication time.
      They also shorten a communication time in a full duplex communication mode and allow proper switching of the full duplex communication at the transmission/reception replacement.
      DIS-CFR signals, EOP-DCN signals, NSS-TSI signals and TSI-DCS signals of a facsimile communication protocol are connected by synchronization signals so that the synchronization signals are sent even after the sending of the protocol signal. Thus, the sending of the synchronization signal for one second when the next protocol signal is sent is not necessary and a time required for the protocol signal is shortened.
      An ANSam signal to disable a function of an echo suppressor is sent when a call is detected and a calling station thereafter sends a protocol signal and an image signal in a manner not to cause signal interruption of 50 ms or longer, and at transmission/reception replacement at the end of the image signal from the calling station, a called station sends an ANSam signal and sends a protocol signal.
    • 传真通信系统和通信设备减少了由于发送/接收的同步造成的丢失时间并缩短了通信时间。 它们还缩短了全双工通信模式下的通信时间,并允许在发送/接收更换时正确切换全双工通信。 传真通信协议的DIS-CFR信号,EOP-DCN信号,NSS-TSI信号和TSI-DCS信号通过同步信号连接,使得即使在发送协议信号之后也发送同步信号。 因此,当下一个协议信号被发送时,发送同步信号一秒钟是不必要的,并且协议信号所需的时间被缩短。 当呼叫被检测到并且呼叫站此后以不引起50ms或更长的信号中断的方式发送协议信号和图像信号时,发送用于禁用回声抑制器的功能的ANSam信号,并且在发送/接收 在来自呼叫站的图像信号的末尾进行替换,被叫站发送ANSam信号并发送协议信号。
