Abstract

PURPOSE:To enable transfer without any operator's work. CONSTITUTION:When a trunk 1 detects reception from a telephone set 6, it notifies a control device 5 of this and, in result, the control device 5 controls a switch 2 so as to connect the trunk 1 with an announcement trunk 3. It gives indication to the trunk 3 and permits the telephone set 6 to transmit announcement. When the transmission of the announcement ends, the control device 5 controls the switch 2 so as to connect the trunk 1 with a register 4 and permits the register 4 to transmit a special dial tone. A caller hears the announcement so as to recognize the dial number of a desired connection destination and additionally dials the number after he hears the special dial tone. The register 4 receives the dial number so as to hold it and the control device 5 controls the switch 2 so as to connect the telephone set 7, for example, being the telephone set of the number with the trunk 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic private branch exchange, and more particularly to a transfer system thereof.

[0002]

2. Description of the Related Art An example of a conventional private branch exchange is shown in FIG.
In this exchange, when an incoming call arrives at the trunk (TRK) 21 from the telephone 6 through the public network, the exchange switch (SW) 2
2 connects the trunk 21 and the relay stand (ATT) 8 (connection A). As a result, a call can be made between the caller and the operator of the relay stand 8. The operator recognizes the transfer destination desired by the caller from the call to the caller, and performs a predetermined operation to transfer to the transfer destination, for example, the telephone set 7. The trunk 21 is connected (connection B).

[0003]

As described above, in the conventional private branch exchange, the operator of the relay stand intervenes at the transfer destination, the operator listens to the information of the transfer destination from the caller, and then selects the transfer destination. It was transferred after performing a predetermined operation. Therefore, there is a problem that the transfer is labor-intensive and cannot be transferred when the operator is absent.

An object of the present invention is to solve the above problems and to provide a transfer selection system for an electronic private branch exchange which enables transfer without requiring human labor.

[0005]

SUMMARY OF THE INVENTION The present invention provides an announcement device for transmitting a predetermined announcement signal and a dial number in a transfer selection system of an electronic private branch exchange having a switch and connecting a telephone and a line. And a register for receiving and holding the line, first control means for controlling the switch to connect the announcement device and the line when an incoming call from the line is detected, and the announcement device makes the announcement. A second control means for controlling the switch to connect the register and the line when the transmission of the ment signal is completed, and the telephone having the dial number received and held by the register and the line. A third control means is provided.

[0006]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 shows an example of an electronic private branch exchange based on the transfer selection system of the present invention. The exchange switch (SW) 2 is connected to the public network through the trunk (TRK) 1, and under the control of the central control unit (CC) 5, the announcement switch
A plurality of telephones including the trunk (ANM) 3, the register (RGT) 4, and the telephone 7 are connected to the trunk 1. The control device 5 is composed of an information processing device, and operates based on a predetermined program. announcement·
The trunk 3 sends an announcement signal including information about users of the plurality of telephones connected to the switch 2 and information about dial numbers of the telephones to the switch 2 under the control of the control device 5. To do. The register 4 receives the dial number through the switch 2 and holds it. The control device 5 is also connected to the trunk 1, the announcement trunk 3, and the register 4, and controls them.

Next, the operation will be described. When the caller turns the dial on the telephone 6 and receives an incoming call to this exchange, the trunk 1 detects the incoming call and notifies the control device 5, and as a result, the control device 5 controls the switch 2 to announce the trunk 1 and the announcement. -Connect to trunk 3 (connection C).
Then, the trunk 3 is instructed to send the announcement signal, and the announcement signal is sent to the telephone 6 through the switch 2, the trunk 1, and the public network. When the transmission of the announcement signal is completed, the control device 5 controls the switch 2 to connect the trunk 1 and the register 4 (connection D), and further the register 4
Send more special dial tone (SDT).

The caller hears the announcement from the trunk 3 and recognizes the dial number of the desired connection destination,
Then, after hearing the special dial tone, additional dial the number.

The register 4 receives this dial number from the switch 2 and holds it, and then the control device 5 receives the number held by the register 4 from the register 4 and connects the telephone of that number, for example, the telephone 7 and the trunk 1. The switch 2 is controlled so as to do so (connection E).

As described above, in the exchange of this embodiment, the caller can select the transfer destination by himself / herself based on the announcement sent from the exchange and can connect to the transfer destination. It is unnecessary.

[0011]

As described above, according to the present invention, an announcement device for transmitting a predetermined announcement signal in a transfer selection system of an electronic private branch exchange having a switch and connecting a telephone and a line, and a dial. The register that receives and holds the number, the first control means that controls the switch to connect the announcement device and the line when an incoming call from the line is detected, and the announcement device sends the announcement signal. When finished, the second control means for controlling the switch to connect the register and the line and the third control means for connecting the telephone and the line of the dial number received and held by the register are provided. And

Therefore, in the electronic private branch exchange based on the transfer selection method of the present invention, a predetermined announcement is sent to the caller, and the caller can select the transfer destination based on the announcement. Then, when the caller dials the transfer destination dial number, it is once held in the register and connected to the telephone of that number by the third control means. That is, since the caller can select the transfer destination and connect, the operator does not need to perform the transfer connection as in the conventional case. Further, since the operator does not need to operate, the caller can always connect to the desired partner regardless of the presence / absence of the operator as in the conventional case.
