Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for confirming central office line number information at the time of a call in an automatic private branch exchange.

[Background technology]

Heretofore, the results of dialing an outgoing call in an automatic private telephone exchange could not be reconfirmed unless the caller was provided with a visual indicator to display the results.

Therefore, if this visual indicator is not present, a call made with incorrect central office number information due to a dialing error will be received by the other party, and the caller will not know that he or she has dialed incorrectly until he/she speaks with the other party. This was one of the reasons for the wrong call.

[Purpose of the invention]

The present invention has been proposed in view of the above-mentioned points.In an automatic private telephone exchange, immediately after the dialing operation at the time of making a call is completed, the central office line number information is transmitted by voice to the caller by a voice synthesizer. To provide a dial confirmation system using voice synthesis that prevents a wrong call due to an erroneous dial operation by informing the caller of the caller's information and having the caller reconfirm it.

[Structure of the invention]

In the dial confirmation method of the present invention, in an automatic local telephone exchange, the called party's office line number information given by a dial operation is determined by a destination identification device, and a dial operation end signal outputted from this distinguishes the central control device from memory. The system is characterized in that the core station line number information stored in the voice synthesizer is given to the voice synthesizer to activate it, and the information is output in the form of voice from the caller's telephone to confirm the dialing operation.

〔Example〕

An embodiment of the present invention will be described below with reference to one drawing.

1 to 3 are explanatory diagrams showing each communication system according to an embodiment of the present invention, and FIGS. 1 and 2 show how an extension subscriber telephone connects an extension subscriber circuit to a communication route switch. Figure 3, which are connected to the outgoing register and the speech synthesizer, respectively, through
The figure shows that a central office line trunk is connected to an extension subscriber telephone via a dial signal sending device or an extension subscriber circuit via a communication path switch.

In the figure, 1 is a central control unit, 2 is a call path switch, 3 is an extension subscriber circuit, 4 is a call register, 5 is a dial numeric keypad, 6 is a destination identification device, and 7 is a destination memory. , 8 is a voice synthesizer, 9 is a central office line trunk, 10 is a dial signal sending device, and 11 is an extension subscriber telephone (note that the calling party is A), and these constitute a communication path system.

Next, a method for confirming office line number information according to the present invention will be explained. In FIG. 1, caller A lifts the handset of extension subscriber telephone 11, hears the dial tone from call register 4, and dials extension subscriber telephone 11 to 4M.
Suppose it is at i.

Here, when the calling party A operates the dial of the extension subscriber telephone 11 to make a call to a predetermined office line, for example, this dial signal, that is, the office line number information is sent to the subscriber circuit 3 and the call path switch 2. i1 sequentially by the sending register 4 via
are counted and accumulated.

This counted and stored office line number information is transferred from the calling register 4 to the central control unit 1, and from there is further stored in the dial number memory 5, and at the same time is directly transferred to the destination identification bag fi6. .

Based on the transferred RLJ line number information, this destination identification device 6 receives a signal indicating that the call is from a central office line and a result of counting the number of digits to determine the end of the dialing operation. The dial operation end number 4T is sent to the central control unit v1.

The central control unit 1 transfers the signal of the destination identification result to the destination memory 1 and temporarily stores it there, while the central control unit fW1 receives the dial operation from the destination identification device 6 as shown in FIG. After inputting the end signal, the office line number information stored in the dial number memory 5 is read out and transferred to the voice synthesizer 8, and the voice synthesizer 8 is switched to the extension line by controlling the call path switch y-2. Subscriber circuit 3-\connect and station i!
Activate voice output of J1 number information.

When the voice synthesis device 8 finishes outputting the office line number information to the calling party A, the voice synthesis device 8 sends output completion information to the central control device 1.

Upon receiving this, the central control unit @1 controls the call path switch 2 to disconnect the speech synthesizer 8 and the extension subscriber circuit 3, and then confirms from the destination memory 7 that the call is from a central office line. Then, as shown in FIG. 3, the communication path switch 2 is controlled to connect the empty office line trunk 9 and the dial signal output path 10 as shown in the communication path (2).

Having finished controlling this connection, the central control device 1 reads the central office line number information from the dial number memory 5 again, transmits it to the dial signal transmitting device 10, and starts transmitting the central office line number information from there. By this activation, the central office line number information is changed to the call route switch? 2 and the central office line connected to the central office line trunk 9 to call the other party. When the other party is called, the central control unit 1 receives a transmission end signal from the dialing signal transmission device RLT10, controls the communication path switch 2, and switches the communication path 9 to the central office line trunk 9 as shown in FIG. 3. is disconnected from the dial signal sending device 10 and connected to the extension subscriber circuit 3 to complete the series of processing.

At this point, caller A reconfirms the office line number information using the voice of voice synthesizer 8, notices a dialing error, etc., and puts down the handset of extension subscriber telephone 11, interrupting the transmission. If the request is abandoned, the series of processes described above will also end midway at that point.

〔Effect of the invention〕

As described above, the present invention has the effect of preventing callers from calling due to erroneous operations by allowing the caller to hear the number dialed using a voice synthesizer and confirming the number.

Claims (1)

[Claims] In an automatic private telephone exchange, there is a memory for storing the telephone number information of the destination, and the central control unit reads out the telephone number information from the memory and outputs it as voice via the caller's telephone. Equipped with a voice synthesizer,
The office line number information of the destination accumulated in the dialing register by the caller's dial operation is stored in the memory via the central control device, and the information is directly transferred to the destination identification device, and the information is transmitted to the destination identification device. In response to a dial operation end signal supported by the discrimination of the information by the destination identification device, the central control device reads out the office line number information stored in the memory and supplies it to the voice synthesizer to activate it, and then starts the call path. A voice synthesizer characterized in that the voice synthesizer connects the voice synthesizer to a caller's telephone by controlling a switch, outputs the office line number information in the form of voice from the handset of the telephone, and confirms dialing operation.
