    Abstract: The facsimile apparatus of the present invention is featured, by the functions of selecting transmission modes of picture signals according to a receiving mode informed of from a called party, for example, of transmitting picture signals representative of a picture reduced in size in case an original documents is larger in size than a recording sheet of paper of activating, in case a called machine is in a automatic reception mode, an acoustic output device incorporated in the called machine through a preliminary telephone talk function to request telephone talk with a called subscriber; and of maintaining a transmission line in its active state to call a called subscriber after transmission of picture signals in case a telephone talk is reserved or, otherwise, releasing the connection after transmission of picture signals in case a telephone talk is not reversed. The above-mentioned functions may be incorporated into a certain transmission protocol thereby accomplishing communication compatibility with other transmission-reception modes of picture signals.

    Abstract: A call transfer apparatus comprises a discriminating circuit to discriminate whether a transfer destination of a call can respond or not and a control unit to control a holding state of the call in accordance with the result of the discrimination. When a speech communication with the transfer destination can be performed, the control unit holds the call. When the communication with the transfer destination is impossible, the control unit releases the holding of the call.

    Abstract: PURPOSE:To keep the quality of speech by improving the utilizing efficiency of a non-voice period and noise immunity by adopting the level of the amplitude of a transmission signal for the method detecting the section of a non-voice block in a conventional system at a receiver side so as to send a non-voice signal for a non-voice period. CONSTITUTION:The system is provided with a voice transmission reception section 11 such as a telephone set sending receiving a voice signal, a non-voice signal insert section 12 inserting a non-voice signal for the non-voice period of the voice signal, a general communication network 13, transmission lines 14, 15, a voice non-voice signal demultiplexer section 16 separating the voice signal and the non-voice signal, a non-voice signal transmission reception section 17 sending/receiving the non-voice signal and a control section 18 controlling the entire communication. Through the constitution above, in place of provision of a period without no signal for the switching of the voice signal and the non-voice signal, a signal with a maximum amplitude decided in advance and the signal is switched by detecting the signal for the switching of noise and signal. Thus, noise immunity and ease of block identification and efficiency are implemented.

    Abstract: PURPOSE:To effectively utilize a control channel by informing a state change at power application and interruption of a mobile set to a stationary set so as to limit a useless occupancy of the control channel. CONSTITUTION:A control section 308 discriminates the presence of other mobile set to which the arrival of a call is to be informed and designates other mobile set to which the arrival of a call is not informed when the other mobile set is in existence. Moreover, when other mobile sets are already noticed of the arrival of the call or the power of all the mobile sets to receive the arrival of the call is turned off, a call tone is outputted through a speaker 3B provided to the stationary set. Thus, even when the power of all the mobile sets is turned off, the power for the mobile set is applied after a call tone outputted from the stationary set is heard and the reply to the arrival of a call is attained by the mobile set.
