Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic automatic telephone exchange having a transfer function.

[Prior Art] Conventionally, in this type of electronic automatic telephone exchange, when a call is made to the opposite station via a trunk line, if the called party has moved to another subscriber, the call is temporarily interrupted. After that, it was necessary to dial again and make the call to the called party, or to have the called party at the opposite station transfer the call to the called party.

[Problems to be Solved by the Invention] The above-mentioned conventional electronic automatic telephone exchange requires dialing again to access the opposite station when making a re-call via a trunk line, and also requires a relay that is a common device. As the call volume is higher than usual on the line, there are many cases where the caller has to wait on the trunk line, and the caller requests to be transferred to a different called party than the actual called party. This has the disadvantage that the operation requires the called party who is not directly involved in the conversation with the calling party.

[Means for Solving the Problems] The electronic automatic telephone exchange with an automatic caller transfer function of the present invention, when connected to a call from a partner station via a repeater,
When the subscriber of the call at the other end confirms the second dial tone and dials the subscriber number corresponding to the destination of the call, a transfer center that analyzes this dialed number and a relay When a subscriber who answers a call from a remote station via the line dials a predetermined common fixed forwarding number, the call is forwarded to a forwarding center, and then the call is forwarded to the forwarded subscriber according to the analysis result of the forwarding center. and control means for setting up a bus between the call and the transferred subscriber after the call is transferred and the transferred subscriber responds.

[Operation] When the called party dials a common fixed forwarding number, which is defined as a special number to request transfer of the call to the transfer center, the call is transferred to the transfer center, and the calling party receives a second dial from the transfer center. After confirming the tone and dialing the forwarding extension, the call is transferred to this forwarding destination, eliminating the need for the called party to dial the forwarding number requested by the caller and The caller from the station need only redial the extension number as the subscriber number to which the caller is being transferred.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an electronic automatic telephone exchange with an automatic caller transfer function according to the present invention.

The electronic automatic telephone exchange 7 of this embodiment has a relay trunk 1
1 and connected to the electronic automatic telephone exchange 1 via a trunk line 19, it has a transfer center 12, a central control unit 9, a switch network 8, a main memory 10, a trunk trunk 11, and a telephone set 13.14. It accommodates. The electronic automatic telephone exchange 1 has a central control processing unit 3, a switch network 2, a main storage device 4, and a relay trunk 5,
It houses a telephone 6.

When the transfer center 12 is connected to a call from the electronic automatic telephone exchange 1 of the destination station via the trunk line 19, it sends out a second dial tone, and the subscriber of the calling telephone 6 dials the second dial tone. After confirming the tone, transfer this call to phone 1.
When the subscriber number corresponding to 4 is dialed, this dialed number is analyzed.

Next, the operation of this embodiment will be explained.

First, logical bus 15 is set up to make a normal call from telephone 6, which is a push-button dialing (DTMF) telephone housed in electronic automatic telephone exchange 1, to telephone 13. The call was routed through trunk line 19 to electronic automatic telephone exchange 7.
, the electronic automatic telephone exchange 7 sends out a ringing signal to the telephone 13 , and when the subscriber of the telephone 13 answers, the central control processor 9 of the electronic automatic telephone exchange 7 sends a ringing signal to the telephone 13 . is set, and telephones 6 and 13 are placed in a talking state. However, now the called party desired by the subscriber of telephone 6 has moved to telephone 14, and telephone 1
It is assumed that the called party No. 3 is not the corresponding calling party desired by the subscriber of the telephone set 6. At this time, the called party on the telephone 13 inputs a common fixed transfer number (for example, hook + "1" (number "1" to be dialed after hooking)), which is a special number that requests transfer of the call to the transfer center 12. When dialed, the central control processing unit 9 transfers the call from the telephone 6 to the transfer center 12, which is a common device.
Calls from
The transfer center 12 sends out a second dial tone, and after confirming the second dial tone, the subscriber of the telephone 6 presses the extension number of the telephone 14 to which the telephone is to be transferred and dials with a button dial signal. do. The central control processing unit 9 transfers the call from the telephone 6 to the transfer destination telephone 14 according to the analysis result of this push button dialing signal by the transfer center 12, and after the subscriber of the telephone 14 responds, the central control processing unit 9 transfers the call from the telephone 6 to the transfer destination telephone 14, and after the subscriber of the telephone 14 responds, the call is transferred to the logical bus 18 is set, and the telephones 6 and 14 are placed in a talking state.

[Effects of the Invention] As explained above, in the present invention, when a subscriber who answers a call from a partner station dials a predetermined common fixed transfer number,
When this call is transferred to a transfer center and the subscriber at the other station dials the subscriber number of the transfer destination after confirming the second dial tone sent out by the transfer center, the call is transferred to the transfer destination. This has the effect that the subscriber who answered the call does not need to dial the forwarding number according to the request of the subscriber at the other station.
