Claims (12)

(57) [Claims] 1. A first notifying means for notifying whether or not a receiver has a function of receiving a sub-address signal to a transmitter, and receiving even if the information amount of the information field of the sub-address signal is extended. A second notifying unit for notifying whether or not the facsimile has a function of performing the facsimile. 2. A signal according to claim 1, wherein a signal indicating whether or not a sub-address signal is transmitted from the transmitter to the receiver, and whether or not the information amount of the information field of the sub-address signal is expanded and transmitted. A facsimile apparatus characterized in that a signal to be represented is included in a digital command signal and transmitted. 3. The facsimile apparatus according to claim 1, wherein said first and second notification means include each notification information in a digital identification signal. 4. A notification that the receiver has a function of receiving a sub-address signal from the receiver and has a function of receiving even if the information amount of the information field of the sub-address signal is extended. A facsimile apparatus characterized in that the amount of information in an information field of a sub-address signal is extended and transmitted from a transmitter to a receiver only when the transmission is performed. 5. The transmitter has selected to transmit by expanding the amount of information in the information field of the sub-address signal, and the receiver has a function of receiving the sub-address signal. A facsimile apparatus characterized in that when there is no function of receiving an expanded amount, a subaddress signal is not transmitted and the fact is displayed. 6. The transmitter has selected to extend and transmit the information amount of the information field of the sub-address signal, and the receiver has a function of receiving the sub-address signal. A facsimile apparatus characterized in that when there is no function of receiving an extended amount of data, communication is not executed and the fact is displayed. 7. The transmission device has selected to extend and transmit the information amount of the information field of the sub-address signal, and the receiver has a function of receiving the sub-address signal. If there is no function to receive the data by extending the amount, the device has means for selecting whether to display the effect without transmitting the sub-address signal or to display the effect without executing the communication. A facsimile apparatus for performing control based on a situation. 8. The presence or absence of a function of receiving a plurality of sub-address signals, a plurality of selective polling signals, and a plurality of password signals, and a function of receiving a modulatable sub-address signal, a variable-length selective polling signal, and a variable-length password by a digital identification signal. A facsimile apparatus having means for notifying the presence / absence of the presence / absence of the digital identification signal. In the case where is selected, means for notifying the length of each sub-address signal by a digital command signal is provided, and the number of password signals, the presence / absence of transmission of a variable length password signal, and transmission of a variable length password signal are selected. In the case of a password, the length of each password signal is Facsimile apparatus having means for notifying the user of the facsimile. 9. The presence or absence of a function of receiving a plurality of sub-address signals, a plurality of selective polling signals, and a plurality of password signals, and a function of receiving a modulatable sub-address signal, a variable-length selective polling signal, and a variable-length password by a digital identification signal. A facsimile apparatus having means for notifying the presence or absence of a polling receiver, wherein the polling receiver, based on the reception of the digital identification signal, determines the number of selective polling signals, the presence or absence of a variable-length selective polling signal, and the variable-length selective polling signal. When transmission is selected, means for notifying the length of each selective polling signal by a digital transmission command signal, the number of password signals, the presence / absence of transmission of a variable length password signal, and the Is selected to send Facsimile apparatus characterized by the having means for notifying a digital transmission command signal and the length of each password signal. 10. The method according to claim 8, wherein said plurality of sub-address signals, a plurality of selective polling signals, and a plurality of password signal reception functions are provided.
The means for notifying the presence / absence of the reception function of the variable sub address signal, the variable length selective polling signal, and the variable length password includes one sub address signal of a predetermined length,
