Abstract

PURPOSE:To prevent mistaken telephone calls by connecting an audio response device to an originating subscriber by a central controller to allow the originating subscriber to confirm the number of a terminating subscriber when the number of the terminating subscriber transmitted from the originating subscriber in accordance with a dial operation and switching the connection of the originating subscriber to connect him to a service trunk. CONSTITUTION:When an originating subscriber SUBA dials the telephone number of a terminating subscriber SUBB, an originating register trunk 1 receives dial pulses of the telephone number of the terminating subscriber SUBB through the route passing a network NW, a network terminals N1N2 from the originating subscriber SUBA to the originating register trunk 1 and reports counting and reception of them to the central controller. Then, when the central controller detects the call to the terminating subscriber SUBB, the central controller disconnects the originating register trunk 1, which is connected to the originating subscriber SUBA till then, and connects an audio response device 2 to the originating subscriber SUBA for the purpose of allowing the originating subscriber SUBA to hear the telephone number of the terminating subscriber SUBB.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to an outgoing connection system in an automatic exchange.

(Prior Art) In the conventional outgoing connection, a caller's dial operation is used to seize a trunk for a call and make a call to the called party. but,
Due to incorrect dialing by the caller or malfunction of the telephone or exchange, the intended callee may not be connected and the call may be connected to a third party. Such mistaken calls cause great inconvenience to both the caller and the called party. Furthermore, in public telephones that store large sums of coins, it is common for users to end up storing large sums of coins in the telephone without being able to talk to the intended party because the change is not returned. Furthermore, in facunmile communication, it is required that the message be accurately transmitted to the called party.

(Object of the Invention) The object of the present invention is to solve the above-mentioned problems of the conventional art. The object of the present invention is to provide an outgoing connection method that allows telephone calls to be made.

(Structure of the Invention) In order to achieve the above object, the present invention accommodates in a network a voice response device that responds with voice to the dial number sent by the caller, and Is the calling number dialed? When the voice response device is received by the call register trunk, the reception result is sent to the central control unit of the automatic exchange, and the central control unit connects the voice response device with the caller and dials the number operated by the caller. is sent from the voice response device, the caller confirms the number, and then the voice response device is released from the network under the control of the central control unit and the caller is reconnected to the trunk for communication. If the confirmed telephone number is incorrect, the caller 1d immediately hangs up the phone.

(Example) An example of the present invention will be described in detail below with reference to the drawings. The figure is a connection diagram showing an embodiment of the outgoing connection method of the present invention.

In the figure, 5UEA is the calling party, 5UBB is the called party, the network is located, N1 to N8 are network terminals that accommodate various trunks, and 1 is the calling register that receives the subscriber number by dialing from the calling party 5UBA. Trunk, 2 is a voice response device that responds by voice with the subscriber number to the calling party 5UBA, 3 is a trunk for talking between the calling party 5UBA and the called party 5UBB, A is the calling party 5U
A relay that monitors BA, Aa is its relay contact, ca,
cb is a DC blocking capacitor, RO"Rg is a relay controlled by TJIJ by a signal distribution device (SD), To""-
Pg is the relay contact, and VOE is the audio device.

Next, the operation will be explained.

First, when the calling party 5UBA dials the telephone number of the called party 5UBB, the calling party 5UBA - the network NW - network terminal N, N2 - the calling party trunk 1 is connected to the calling party trunk 1 by the route of the calling party 5UBA - network NW - network terminal N, N2 - the calling party trunk 1 Caller SUB
It receives a dial pulse that is B's telephone number, and notifies a central control unit (not shown) that the count has been received.

Then, when the central controller learns that the call is for the called party 5UBH, it sends the called party 5UBB to the calling party 5UBA.
In order to hear the telephone number of , the outgoing caller trunk 1 that has been connected until now is disconnected, and the voice response device 2 is connected.

Calling party 5 UBA - network NW - network terminals N3, N4 - terminal A3 in voice response device 2 - relay A, . . . - 4,8V power supply roof is established, and relay A operates. Therefore, contact A8 of relay A operates to perform scanning transmission (SCN). A central control unit (not shown) reads the SCN transmission result and drives a signal distribution device (SD) (not shown). This signal distribution device (SD) operates the ring-Ro%R9 corresponding to the telephone number of the called party 5UBB. When this relay contact ro-r9 operates, a gate circuit to the audio device VOE is completed. The audio device VOE responds by voice with the numbers in the order in which relays Ro to R9 operate.

That is, the telephone number of the called party 5UBB is answered by voice.

In this case, the route is caller 5UBA - network NW
- Network terminals N3, N4 - DC blocking capacitors Ca, C5 in the voice response device 2 - Voice device VOE - Relay contacts ro with numbers 0 to 9 corresponding to the telephone number of the called party SUB
”-rg - earthly.

Next, the central control device (not shown) controls the calling party 5UBA to the dial ξ route (telephone number of the called party 5UBB) in the signal distribution device (SD) not shown, and when finished, the calling party 5UBA In order to connect to the called party 5UBB, disconnect the voice response device 2 that was connected at the neck,
Connect the telephone trunk 3.

Furthermore, this trunk 3 and the called party 5UBB are also connected. Therefore, calling party 5UBA-network NW-talking trunk terminal N5rN6-talking trunk 3-
Network terminal N 7 r N B - Network Hiro - Route of called party 5UBB A calling party 5UBA and a called party 5UBB make a conversation. Therefore, the calling party 5U
When the BA is connected to the voice response device 2, the telephone number of the called party 5UBB can be confirmed by the numbers provided by the voice response.

If the phone number you checked is incorrect, hang up the phone immediately.

(Effects of the Invention) As explained in detail above, the present invention allows the calling party to confirm the dialed number of the called party using a voice response device, and then connect the called party. This eliminates the possibility of making the wrong call. In addition, in a public telephone set that accommodates high-value coins, it is possible to eliminate the need to store high-value coins due to incorrect calls. Further” 11
For important lines such as ``0'' and ``19'' dials, the timing is taken to confirm whether the dial is incorrect before connecting, but for important lines, it is necessary to shorten the time as much as possible. If the number can be confirmed using the voice response device as described above, there will be no need to take the timing to prevent mistaken connections as described above.Furthermore, in facsimile communication, when performing FAX communication, it is necessary to ensure that the message is sent to the intended party. It can be seen that the message has been sent.It is particularly effective for communicating confidential messages.
