Abstract

PURPOSE:To ensure the talking independently whether a person resides in the opposite party or not by generating a command by a telephone call signal, sending it, allowing the called terminal equipment uses the command so as to identify a telephone number of a caller terminal equipment, forming it into a format set in advance and printing out the result. CONSTITUTION:In giving a dial from a caller terminal equipment 10, the called terminal equipment 30 receives a call tone to send a called identification signal. In depressing a button at that time, an LCD display section 36 displays the telephone reservation and a generating circuit 14 generates a command to change the procedure from the conventional facsimile communication procedure into the telephone reservation procedure. Then a system control circuit 12 analyzes the command to execute the result of analysis. When the operator resides in the called terminal equipment 30 and depresses a reply button on an operation panel 37 within a prescribed time, an analysis circuit 33 sends a retrain affirmative signal to switch the line 50 from the caller terminal equipment 30 into the telephone set side.

Description

[Detailed description of the invention] Industrial applications The present invention relates to facsimile communication systems.

Conventionally, in a facsimile communication system, as shown in FIG. 4, when the calling station turns a dial (step (hereinafter referred to as ST) l), the called station detects a ringing tone, and this detection causes the CED ( tonal signal), N5F (non-standard function identification signal), C3l (called station identification signal) and DI
S (digital identification signal) is sent to the calling station, and the calling station receives these signals (Sr1, 5T3) and proceeds with the facsimile communication procedure.

In addition, in such facsimile communication systems,
For example, in a facsimile communication system that allows telephone calls, a switch for telephone reservations is installed on each of the calling station and the called station. There is a known system in which a telephone call is started after the facsimile communication is completed by operating a switch.

Problems to be Solved by the Invention However, in such conventional facsimile communication systems, when a call is made for the purpose of making a call to the called party connected via a telephone line, the telephone reservation is not made immediately after the call is made. Even if the user presses the switch, the push signal is not accepted, so a call cannot be made, and there is also a problem in that a message indicating that a call is to be made cannot be sent to the other party.

The above problem arises for the following reasons. In other words, in the case of automatic call origination, when CED is detected from the called station, the calling station sends NSF.
, C8I, and DIS commands, so the push signal for the telephone reservation switch could not be accepted. Further, in the case of manual call origination, the press-down signal of the switch for switching lines between the telephone side and the facsimile side was not accepted.

The present invention has been made in view of the above-mentioned problems, and is a facsimile communication system that allows a user to easily communicate with a called party or leave a telephone message on the other party's facsimile machine by performing normal facsimile communication procedures. The purpose is to provide a system.

Means for Solving the Problems In order to achieve the above object, the present invention provides means for the calling side terminal to send a telephone call signal to the called side terminal according to the facsimile procedure, while the called side terminal It has a means for identifying the oscillation source of the telephone call signal, a means for receiving the telephone call signal and transmitting a response signal to the calling side terminal, and a predetermined format. The present invention is characterized by comprising a means for adding the processing result of the identification means to this format and outputting the result.1) Function The present invention is characterized in that when a telephone call signal is sent by the above-mentioned structure, if there is an operator on the other party's side, the telephone If there is no operator available, identification information of the calling party can be added and indicated in a predetermined format.

Embodiment FIG. 1 is a block diagram showing a facsimile communication system according to an embodiment of the present invention.

In FIG. 1, 10 is a calling terminal, and Node is a called terminal connected to the calling terminal 10 via a telephone line.

Further, 3] is a line control circuit that controls the connection between the telephone line and the called terminal I, 32 is a modem that demodulates commands and document information received from the calling terminal 10, and 33 is a control circuit that analyzes commands. A command analysis circuit (hereinafter referred to as analysis circuit), 36 is a system control circuit that controls each circuit of the called terminal, a recording device that prints out the analysis results and document information of the open analysis circuit 33, and 36 is a recording device of the analysis circuit 33. an LCD display section that displays the analysis contents in response to the analysis; 3;
Reference numeral 7 denotes an operation panel having a response button operated to respond to a command and establish a call state.

The analysis circuit 33 takes in the command, identifies the telephone number of the source of excavation, and identifies the contents of the command.

The analysis circuit 33 also uses the operator's I/O at the calling terminal IO.
Identify when the D number is pressed.

For example, as shown in Figure 2, open the system control circuit.
I received a phone call from... Format information including the text "Please call the contact number below" is prepared in advance, the year, month, date and time are calculated, and the year, month, date and time and the processing result of the analysis circuit 33 are added to the predetermined positions of the format information. Transfer to the recording device 35.

The operation of the facsimile communication system configured as described above will be explained with reference to the flowchart shown in FIG.

When dialing is performed on the calling terminal 10 (step (
(hereinafter referred to as ST) 61), the called terminal side receives CNG (ringing tone) (ST 62), sends CED (called identification signal) (ST 63), and then N5F (non-standard function). identification signal), C3l (called station identification signal), and DIS (digital identification signal) are sent to the calling terminal IO (ST64). On the other hand, when the calling terminal 10 detects CED (ST65), NSF and C8
It enters the state of waiting for I and DIS (ST66).

If the button is pressed at this time (ST67), the LCD display will open and display for telephone reservation will be displayed (ST68), and at the same time, the creation circuit 14 will generate a command to change from the normal facsimile communication procedure to the procedure for telephone reservation. . and,
The system control circuit 12 analyzes the command and executes the analysis result.

Next, the calling terminal IO sends N5S (non-standard setting command) and TSI (transmitting station identification signal) (5T69),
At that time, a telephone reservation command is also sent. Note that the operator's ID number is also sent at this time. On the other hand, when the called terminal side receives NSS and TSI (S, T2O), the analysis circuit 33 identifies the telephone number of the calling terminal 10 and analyzes the command contents.

Then, the LCD display section 35 displays that a telephone reservation has been made (ST71).

When an operator at the called terminal side presses the response button on the operation panel 37 within a certain period of time (ST72), the analysis circuit 3
3 sends an RTP signal (retrain affirmation signal) 5T
73), the line is switched from the called terminal (9) to the telephone side.

On the other hand, after the calling terminal 10 issues NSS and TSI,
Wait for the RTP signal! 0 (ST74), upon receiving this signal, it recognizes that the called terminal is ready for a call, and displays this on the LCD display section 13, while transmitting the signal between the telephone lines from the calling terminal 10 to the telephone. Switching, called terminal I
(ST 75. ST 76)
.

If there is no operator on the called terminal side yet and the answer button is not pressed even after a certain period of time has passed after receiving the telephone reservation command (ST72), the system control circuit will change to a predetermined format after the certain period of time has passed. Image information is generated in which the current date and time and the telephone number of the calling terminal IQ are added, and this is transferred to the recording device 35 and printed out as a message (ST77). An example of the message print output is shown in FIG. On the other hand, after issuing N5SXTSI, the calling terminal 10 waits for an RTP command from the called terminal I as described above (
ST74), and if no RTP command is received after a certain period of time, the connection to line I is disconnected (ST78).

Effects of the Invention As is clear from the above explanation, the present invention creates and sends a command using a telephone call signal, while the called terminal uses the command to identify the telephone number of the calling terminal and sets this in advance. Since you can subscribe to the format and print it out, you can make a call if there is someone on the other end, and even if there is no one on the other end, you can leave a message and be sure to let the other person know that you have called. has.
