送信する。(a) In the case of priority level The control unit 9 determines whether or not to accept the broadcast based on the number of broadcast destinations. When accepting the broadcast, it uses the memory having the call control memory configuration shown in FIG.
The facsimile terminal 4 is controlled by. The control unit 9 uses the receiving call control memory 12 to send a special signal (for example, a 2100 Hz sine wave signal) to the telephone 1 via the exchange 7, and connects the facsimile terminal 4 to the facsimile storage and conversion device 8 for the caller A. instruct them to do so. The control section 9 uses the reception call control memory 12 to exchange transmission control signals with the facsimile terminal 4, and then stores the facsimile signals in the facsimile signal storage device 11. After the storage is completed, the control unit 9 uses the transmission call control memory 14 to send a special signal to the facsimile terminal 5 via the exchange 7, puts the facsimile terminal 5 into a communication state, and after exchanging transmission control signals, sends a special signal to the facsimile terminal 5 via the exchange 7. At the same time as transmitting the facsimile signal stored in the signal storage device 11 to the facsimile terminal 5, a special signal is sent to the facsimile terminal 6 of the called party C via the exchange 7 using the transmitting call control memory 15, and the facsimile terminal 6 After entering the communication state and exchanging transmission control signals, the facsimile signal storage device 11 transmits the facsimile signal stored in the facsimile signal storage device 11 to the facsimile terminal 6.

The facsimile terminal 4 is controlled by. Using the receiving call control memory 13, the control unit 9 sends a special signal to the telephone 1 via the exchange 7 to instruct the caller A to connect the facsimile terminal 4 to the facsimile storage and conversion device 8. The control section 9 uses the reception control memory 13 to exchange transmission control signals with the facsimile terminal 4, and then stores the facsimile signals in the facsimile signal storage device 11. After the storage is completed, the control unit 9 uses the transmission call control memory 16 to first send a special signal to the facsimile terminal 5 of the called party B via the exchange 7, putting the facsimile terminal 5 into a communication state, and transmitting and receiving the transmission control signal. After going,
The facsimile image signal is transmitted to the facsimile terminal 5. After the transmission to the facsimile terminal 5 is completed, the control unit 9 uses the transmission call control memory 16 again to send a special signal to the facsimile terminal 6 of the called party C via the exchange 7, putting the facsimile terminal 6 into a communication state and controlling the transmission. After exchanging the procedure, the facsimile signal stored in the facsimile signal storage device 11 is transmitted to the facsimile terminal 6.

い。 In the above embodiment, the number of broadcast destinations is 2, but in general, when the number of broadcast destinations is N, (a) at the priority level, one reception call control memory and one transmission call control memory N
(b) At the normal level, only one call control memory for reception and one call control memory for transmission are used. Therefore, for the number of broadcast destinations N, the memory usage amount for (b) normal level may be smaller than the memory usage amount for (a) priority level by N-1 transmission call control memories.

る同報宛先数を決定すればよい。 In the embodiment described above, the number of broadcast destinations is set to a predetermined value, but at the time of accepting a new call, information on the total number of destinations of the priority level and normal level currently being accepted is provided. It is also possible to variably determine the number of broadcast destinations that can be accepted at each subsequent level based on the following. In this case, when the control unit 9 receives the call control information from the exchange 7, the control unit 9 determines the amount of call control memory used at the priority level, the amount of call control memory used at the normal level, and the amount of memory of the entire system. The number of broadcast destinations to be accepted at the priority level and the normal level can be determined based on these values.

効利用が可能である。 Because of this structure, even if a large number of broadcast calls are temporarily input, the amount of call control memory used can be reduced by allowing the caller to distinguish between the priority level and the normal level. It is possible to reduce the number of call acceptance rejections. Furthermore, by separately setting the allowable number of destinations at the priority level and the allowable number of destinations at the normal level, it is possible to effectively utilize the call control memory according to traffic conditions.

This has the advantage that call acceptance rejections can be reduced and serviceability can be improved.

送方式。[Scope of Claims] 1. In a store-and-forward method in which information from a calling terminal is temporarily stored in a storage device in a store-and-forward device, and then the information is transmitted to a receiving terminal, the information is transmitted to a plurality of destination receiving terminals. In this case, the memory for storing call control information for transmission is prepared for one destination in the storage device, and the normal level is used to sequentially use the memory to send to the plurality of destinations. A memory for storing call control information for transmission is prepared for the number of the above-mentioned plurality of destinations, and a priority level is set to simultaneously use the memory to transmit to the above-mentioned plurality of destinations, and new calls requesting broadcast communication are set. Each time a message is accepted, the amount of call control memory used at the priority level, the amount of call control memory used at the normal level, and the amount of memory for the entire system are calculated, and based on the calculated values, the allowable number of destinations for each subsequent level is calculated. A broadcast communication delivery method characterized in that the number of calls is determined to be less likely to be rejected.
