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.

Claims

1. A transmitting method between a calling facsimile machine and a called facsimile machine, where the calling facsimile machine has a dial number storing means, a transmission rate selection means for selecting a transmission rate from a plurality of transmission rates, and a control signal transmission means where the calling facsimile machine has stored in the dial number storing means, the dial number of the called facsimile machine, said transmitting method comprising the steps of:

storing said dial number in said dial number storing means when a facsimile transmission is made at a highest rate of said calling facsimile machine and said dial number was not previously stored;

performing the following steps when said dial number is previously stored;

selecting the dial number of said called facsimile machine from said dial number storing means of said calling facsimile machine;

calling the called facsimile machine;

transmitting a first control tone signal from said calling facsimile machine to said called facsimile machine;

said called facsimile machine transmitting a digital identification signal to said calling facsimile machine and said calling facsimile machine receiving said digital identification signal from said called facsimile machine;

said called facsimile machine transmitting a second control tone signal to said calling facsimile machine, said second control tone signal indicating that said first control signal has been received, and

said calling facsimile machine transmitting a third control tone signal to said called facsimile machine, said third control tone signal indicating that a facsimile message should be transmitted to said called facsimile machine upon receipt of said second control signal and then,

said calling facsimile machine transmitting the facsimile message to said called facsimile machine.

2. A transmitting method between a calling facsimile machine and a called facsimile machine, where the calling facsimile machine has a dial number storing means, a transmission rate selection means for selecting a transmission rate from a plurality of transmission rates, a judging means for judging a non-standard facilities signal which contains information about the called facsimile machine and if the called facsimile machine can receive a transmission made at the highest available of said plurality of transmission rates, and a control signal transmission means where the calling facsimile machine has stored in the dial number storing means, the dial number of the called facsimile machine, and a control signal receiving means for receiving a control signal, said transmitting method comprising the steps of:

storing said dial number and a receiving station information in said dial number storing means when a facsimile transmission is made at a highest rate of said calling facsimile machine and said dial number was not previously stored;

performing the following steps when said dial number is previously stored;

selecting the dial number of the called facsimile machine from said dial number storing means of said calling facsimile machine;

calling the called facsimile machine;

transmitting a non-standard facilities signal and a digital identification signal to said judging means of said calling facsimile machine from said called facsimile machine;

determining if the facsimile non-standard facilities signal and digital identification signal coincide with information stored in said storing means;

when the facsimile non-standard facilities signal and digital identification signal coincide with information stored in said storing means, then;

transmitting a first control tone signal from said calling facsimile machine to said called facsimile machine;

transmitting a second control tone signal from said calling facsimile machine to said control signal receiving means of said calling facsimile machine, said second control tone signal indicating that said first control has been received, and

said calling facsimile machine transmitting a third control tone signal to said called facsimile machine, said third control tone signal indicating that a facsimile message should be transmitted to said called facsimile machine upon receipt of said second control signal and then,

said calling facsimile machine transmitting the facsimile message to said called facsimile machine after a predetermined time elapses.

3. A transmitting method between a calling facsimile machine and a called station, where the calling facsimile machine has a dial number storing means, a transmission rate selection means for selecting a transmission rate from a plurality of transmission rates, a judging means for judging a non-standard facilities signal which contains information about the called facsimile machine and if the called station can receive a transmission made at the highest available of said plurality of transmission rates, and a control signal transmission means where the calling facsimile machine has stored in the dial number storing means, the dial number of the called station, and a control signal receiving means for receiving a control signal, said transmitting method comprising the steps of:

storing said dial number and non-standard facilities signal including receiving station information in said dial number storing means when a facsimile transmission is made at a highest rate of said calling facsimile machine and said dial number was not previously stored;

performing the following steps when said dial number is previously stored;

selecting the dial number of the called station from said dial number storing means of said calling facsimile machine;

calling the called station;

transmitting a non-standard facilities signal and a digital identification signal to said judging means of said calling facsimile machine from said called station;

judging that the facsimile non-standard facilities signal does not coincide with information about said called station stored in said storing means;

clearing the dial number of the called station and the information containing non-standard facilities signal from said dial number storage means when the facsimile non-standard facilities signal does not coincide with information about said called station; and

transmitting the facsimile communication to said called station through a normal transmission procedure.
