Abstract
In the present invention, a transmission control procedure from the time when a calling facsimile receives a digital identification signal from a called facsimile to the time when the calling facsimile transmits a facsimile message is carried out by control signals using tone signals. For example, the calling facsimile sends out to the called facsimile a first control signal indicating that facsimile transmission should be performed through a particular procedure if it receives the digital identification signal from the called facsimile. The called facsimile sends to the calling facsimile, if it receives the first control signal, a second control signal indicating that the first control signal is received. The calling facsimile sends out to the called facsimile a third control signal indicating that a facsimile message should be sent and then, sends out the facsimile message to the called facsimile if it receives the second control signal.
