The software 129 of the SW unit 104
Detects that a special number for broadcasting control activation has been input from the subscriber side, and performs a process of setting a path to the CH distribution unit 122 and the voice response unit 124.

(Embodiment) Next, an embodiment of the facsimile simultaneous broadcasting system of the second embodiment will be described.

In FIG. 6, the transmission FAX terminal 110 of the subscriber circuit (0) 106 is connected to the reception FAX terminal (A) (TEL 03-9876-5432) of the subscriber circuit (1) 107 and the subscriber circuit.
(2) 108 reception fax (B) F (TEL 03-1234-5678)
A configuration for performing AX broadcast communication will be described below as an example.

The operation flow is shown in FIG. 9, and the broadcast protocol sequence is shown in FIGS.

First, a special number, here, for example, 1234 is inputted from the subscriber side.
A number is input with, for example, # (301). As an example, “234 # 0398765432 # 0312345
678 # "or the like. Thereafter, the broadcast communication is started (301).

The SW unit software 129 sets a path from the special number 1234 to the CH distribution unit 122. For example, as shown in FIG. 7, the transmitting FAX terminal 110 is assigned to CH0 of HW0.
FAX terminal (A) 11
1 (FAX of 03-9876-5432), a path is set to CH2 so that data can be transmitted to the receiving FAX terminal (B) 108 (FAX of 03-1234-5678).

Also, as described in FIG.
In H0, data transmission to the transmission FAX terminal 110, CH
1 receives data from the receiving FAX terminal (A) 107, C
A path is set in H2 so that data can be received from the receiving fax terminal (B) 112.

When a path is set and an incoming call arrives at the receiving FAX terminal, the receiving FAX terminals 111 and 112
01 and 402 and DISs 403 and 404 are transmitted.

Monitoring unit (1) 201 and monitoring unit (2) 202
The monitoring unit (31) 231 sequentially monitors the PCM data from the CH1 and the PCM data from the CH2 of the HW1, and performs CSI 401, 402, DIS 40 shown in FIG.
When 404 and 404 are detected, the TEL number and the like are read from the CSI 401 and 402 and stored in the memory 240.

At this time, DIS is the earliest among the channels.
Is received, the timer 451 is reset and started.

CSI / DIS / CFR / MCF sending unit 2
At 41, when the time exceeds the time set by the timer 451, the improved C
The SI 403 is sent to CH0 and sent to the sending FAX terminal 110 (303).

The value of the time-over at this time is determined by T.P. in each phase, including timers 452 and 453 described later. The time is set so as not to exceed the time defined in 30.

Next, the information from each of the DISs 403 and 404 is read and an improved DIS 406 is created under AND conditions.
Send to CH0 and send to sending FAX terminal 110.

At this time, for example, the modem speed setting and EC
In M (Error Correction mode), CH1
9600bps, with ECM, 4800b for CH2
If there is no ps and no ECM, 4800 bps ECM
An improved DIS 406 is created, such as none.

Here, the processing without ECM will be described first.

In the process with ECM, there is also a process of retransmitting an image, which will be described later.

All signals from the transmitting FAX terminal 110 to the receiving FAX terminal (A) 111 and the receiving FAX terminal (B) 112 are distributed and transmitted as they are. That is, D
CS 407 to DCS 408 and DCS 409, CFR
413 and CFR414 to CFR415, PIX42
0 to PIX421 and PIX422, ECP423 to ECP424 and ECP425, DCN429 to DC
MCF444 to MCF4 to N430 and DCN431
45 and the MCF 446.

Next, according to ITU-TT. The monitoring unit (1) 201 and the monitoring unit (2) 202 transmit the received FAX
The CFRs 410 and 411 sent from 107 and 108 are monitored.

At this time, the timer 452 is reset and started when the CFR is received at the earliest in the CH where the DIS is detected.

When the timer 452 times out or when CFR is received from the CH in which DIS is detected, the sending unit 241 sends the CFR 415 from the sending FA.
Send to X terminal 110. Then, PIX420,4
21, 422 and EOPs 423, 424, 425 are transmitted and received.

Next, according to ITU-TT. 30 sequences,
In the procedure signal of the phase after transmitting the image information, the monitoring unit 1
(201) The monitoring unit 2 (202) monitors the MCFs 426 and 427 sent from both the receiving FAX terminals (A) 111 and the receiving FAX terminals (B) 112.

At this time, the timer 453 is reset and started when the MCF is received as soon as possible in the CH where the DIS is detected.

Then, M corresponds to the number of CHs where DIS is detected.
When a CF is received, an MCF 428 is sent from the sending unit 241 as shown in FIG.

Here, for example, as shown in FIG. 14, it is assumed that the MCF 426 is received from CH1, and the MCF 427 (which is originally transmitted as shown in FIG. 12) cannot be received from CH2, so that the time is over.

At this time, whether or not the MCF has been received is recorded in the memory 240 described in the CSI / DIS described above. Here, the CS of the receiving FAX terminal (A) 111
The MCF426 received flag is described together with I401. (However, if there is a CH that returns FTT without entering the image signal phase, it is determined that the line state is bad and abnormal termination is performed).

At this time, the MCF 444 is transmitted to CH0, the DCN 429 is transmitted from the transmitting FAX terminal 110, and the transmitting FAX terminal 110 and the receiving FAX terminal (A) 1 are transmitted.
The 11 side is terminated normally.

After the end of the broadcast, the operator on the transmitting FAX terminal 110 again sends the special number and the voice response unit 1 again.
TEL to 24 (305).

The special number at this time is the aforementioned improved CSI4
Enter the password described in 03.

Based on the password and the TEL to the voice response unit 124, a path is connected to the voice response unit 124 activated by the password on the software 129 side of the SW unit.

The voice response unit 124 checks the normality of the password, reads the CSI 401 and 402 and the MCF reception flag stored in the memory 240 of the CH distribution unit, converts them into voice patterns, and converts them into voice patterns. Voice guidance is provided to the 110 operator.

In the voice response unit 124, CSI / DIS /
Monitors the reception memory 240 of the MCF, starts when the DIS is described in any CH, converts it to a voice pattern at all times, sets a path, and can always send it using a counter. Keep it.

For example, “1st, 03-9876-543
Sent to 2 successfully. 2nd, 03-1234
It was not sent to -5678. As described above, by giving voice guidance to the operator of the transmitting FAX terminal 110, the transmitting-side operator can confirm the incoming call state of the broadcast (306).

Since the CSI is a non-standard signal, some received faxes are not transmitted. In this case, the other party's telephone number is unknown, and at this time, only the voice saying, "Sent to the first party successfully."

Here, in the ECM communication, in the phase after image transmission, there is retransmission control when the line condition is poor, so the control is different.

If the line condition is poor, a retransmission request is made from the receiving FAX terminal using a PPR signal composed of information requesting retransmission of image data.

At this time, the retransmission frame requested by the PPR from all the receiving FAX terminals is ORed to request the transmitting FAX terminal 110 by the PPR.

Although the broadcast control of FAX has been described above, this broadcast communication method is not limited to FAX communication, but can be applied to other data communication. That is, by storing ACK information after transmission of data information (an MCF-equivalent signal in a facsimile) in a memory, a similar service can be provided.

[0079]

As described above, according to the present invention, the reception FA
The information of the X terminal is stored in the memory, the broadcast is performed based on the information, the MCF from the receiving FAX terminal is monitored, and the result of the incoming call is converted into a voice.
Communication can be performed all at once without using a special FAX terminal, and the caller of the sending FAX terminal can confirm the incoming information to each receiving FAX terminal by voice after broadcasting. There is an effect that it becomes possible.
