2. Description of the Related Art Conventionally, an automatic transmission device of this type has been used for the purpose of controlling the start / stop of automatic transmission, line switching control, and selection of a telephone number of a destination from a terminal device. For example, Japanese Patent Laid-Open No. 61-288645 discloses a means for detecting a dial signal transmission start signal from a terminal device, a means for storing a telephone number of the other party and transmitting it to a subscriber line, and a response completion signal for the other party. A technique is disclosed in which a means for transmitting to a terminal device automatically makes a call to one partner telephone number with a single dial signal transmission start signal.

[0003]

In this conventional automatic transmission device, since the transmission is limited to one destination telephone number for one transmission request, the connection to the terminal of the destination telephone number is made. If it was not possible, there was a problem that the call was terminated with the connection failed. for that reason,
It was not efficient because the terminal side had to issue a call request again and instruct automatic calling.

[0004]

In order to solve the above-mentioned problems, the automatic transmission device of the present invention is provided with a storage means for storing a plurality of telephone numbers of the other party, and further, a failure of the transmission to a certain telephone number of the other party. When it is detected, a calling means for calling another telephone number of the other party is provided.

[0005]

By storing a plurality of telephone numbers of the other party in advance, even if the line cannot be connected by one telephone number of the other party, the other telephone numbers are successively transmitted. This enables an efficient automatic transmission operation.

[0006]

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention.
In FIG. 1, an automatic transmission device 1 is connected between a terminal device 2 and a subscriber line 3. The configuration includes a control line interface circuit 10, a dial control circuit 11, a partner number recording circuit 12, and an input means 13. Further, the terminal 2 uses the control lines 21 and 20 to connect the dial control circuit 1
1 and the control line interface 10, respectively.

The control line interface 10 includes a control line 2
When the transmission start signal a sent from the terminal 2 via 0 is detected, the transmission request signal b is output to the dial control circuit 11. The dial control circuit 11 is connected to the control line interface circuit 10, the partner number storage circuit 12, the control line 21, and the subscriber line 3, and when the call request signal b is detected, a number preset from the partner number storage circuit 12 is set. Is read and transmitted to the subscriber line 3. When the dial control circuit 11 detects the response of the other party, the control line 2
The connection completion signal c is sent to the terminal 2. If no response is detected, another number is read from the other party number storage circuit 12 to make a call.

Next, the operation of the circuit shown in FIG. 1 will be described. When the control line interface circuit 10 detects the transmission start signal a from the control line 20, it generates a transmission request signal b and outputs it to the dial control circuit 11. The other party's number storage circuit 12 can store a plurality of telephone numbers, and these telephone numbers can be read by the dial control circuit 11 by being input by the input means (ten-key etc.) 13. The other party's telephone number is not the input means 13, but the terminal 2
You may be able to input from.

The dial control circuit 11 sends a call request signal b
When one is detected, one telephone number is read from the partner number storage circuit 12 and the number is transmitted to the subscriber line 3. When the dial control circuit 11 cannot detect the other party's response within a certain period of time or detects a connection failure (for example, a busy tone is detected), it reads out another telephone number from the other party number storage circuit 12 and transmits it. To do.

The dial control circuit 11 sends out a connection completion signal c to the terminal 2 through the control line 21 when the response of the other party can be detected. The dial control circuit 11 can connect to a partner of one number, fail to connect to all telephone numbers set in the partner number storage circuit 12, or connect to a partner of any one number. Before that, when the transmission request signal b is turned off, the transmission operation is ended.

FIG. 2 is a block diagram showing a configuration example of the dial control circuit 11 in this embodiment. 2, the dial control circuit 11 includes a timer circuit 41, a connection completion detection circuit 42, a connection failure detection circuit 43, and a transmission circuit 4.
4, the other party number reading circuit 45. Each of the circuits described above may be configured by hardware (electronic circuit) for each circuit, and a part of the circuit may utilize a computer to realize a function of each circuit by operating a CPU according to a predetermined program. You can also

When the timer circuit 41 receives the signal d during transmission from the transmission circuit 44, it starts counting the time, and when the counter value reaches a certain value, the next number transmission request signal e
To the transmitting circuit 44. As for the counter value, the signal d during transmission is O
It is reset when it becomes FF.

When the connection completion detecting circuit 42 receives the response signal from the subscriber line 3, the connection completion detecting circuit 42 outputs the connection completion signal c to the control line 21.
It is supplied to the transmitting circuit 44. Connection failure detection circuit 43
Detects a signal indicating a connection failure from the subscriber line 3 and sends a connection failure signal f to the transmission circuit 44. The other party number reading circuit 45 reads the other party number h from the other party number storage circuit 12 according to the number request signal g from the originating circuit 44 in a predetermined order and supplies it to the originating circuit 44.
In addition, when all the other party numbers have been supplied, the other party number end signal is issued to the transmitting circuit 44.

When the transmission circuit 44 receives the transmission request signal b from the control line interface circuit 10, it outputs a number request signal g to the other party number reading circuit 45, and when it receives the other party number h, it sends to the subscriber line 3 with this number. At the same time as making a call, the signal d during transmission to the timer circuit 41 is once turned off and then turned on. After that, when the connection failure signal f is received from the connection failure detection circuit 43, or when the next number transmission signal e is received from the timer circuit 41, the number request signal g is again output to the partner number reading circuit 45 and received. Call the subscriber line 3 with a number. The transmitting circuit 44 receives the partner number end signal from the partner number reading circuit 45, receives the connection completion signal c from the connection completion detecting circuit 42,
When the transmission request signal b from the control line interface circuit 10 is turned off, the transmission operation is finished.

The above operation will be described in summary with reference to the flow chart of FIG. 3. First, the transmission circuit 44 checks whether the transmission request signal b is issued (301), and if it is issued, one telephone number of the other party is sent. Send (302). After that, it is checked whether it is connected to the other party's telephone number (303) and whether the connection is unsuccessful (304). If not, it is checked whether a fixed time has passed (305). If not, the process returns to step 302. The same operation is repeated. If the time has passed, another phone number will be sent (30
6), steps 302 to 304 for other telephone numbers
The same operation as is repeated (306). If you cannot make a connection by calling all the stored phone numbers of the other party (30
8) Then, the transmission operation ends (309).
