JPH0371769A - Automatic exchange with extension mutual interrupt propriety selection function - Google Patents

Abstract

PURPOSE:To avoid a trouble between talkers caused when interrupt talking is established forcibly by displaying caller additional information onto a called telephone set when a caller requests an interrupt setting, operating an interrupt propriety selection button of a telephone set by the called party observing the additional information and setting the interrupt at the selection of enabled interrupt. CONSTITUTION:When a caller dials a special number requesting an interrupt setting during a busy state of a called party, additional information 16 stored in an additional information storage area 11 is retrieved from a caller telephone number, displayed on a subscriber additional information display section 14 of a called part telephone set, and when a called party observing the additional information operates an interrupt propriety selection button 13 of the telephone set to select the interrupt enable state, the interrupt is set and when the called party operates the interrupt propriety selection button 13 of the telephone set to select the interrupt rejection, the interrupt talking is rejected. Thus, a trouble between talkers caused when the interrupt talking is established forcibly is reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic switching system, and more particularly to a mutual extension system.

[Prior Art] In a conventional automatic switching system, when the called party is busy, when the caller makes an interrupt request by dialing a special number or the like to interrupt the call, the central control system that receives the request The device forced the caller to connect to the busy line, creating an interrupt call.

[Problems to be Solved by the Invention] In the conventional extension mutual interruption method described above, when the calling party performs an operation to request an interruption, the called party does not know that an interruption is requested or that the interruption is requested. If the person making the interrupt request is not known and the caller requests an interrupt, the caller is forcibly connected to the busy line and the interrupt call is established, which often causes trouble between the callers. The disadvantage is that it occurs.

SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic switching system with a function of selecting whether or not to allow mutual extensions to interrupt, which eliminates troubles between callers that occur when an interrupt call is forcibly established.

[Means for Solving the Problems 1] The automatic switchboard with the function of selecting whether or not to allow mutual extensions to interrupt according to the present invention accommodates a telephone set having a subscriber additional information display section and a button for selecting whether to allow or not to interrupt, and in accordance with the telephone number, Additional information storage area that stores additional information that, when displayed on the subscriber additional information display section of the subscriber's called telephone, allows the called party to select whether or not to accept an interruption from the calling party. When the caller dials a special number requesting interrupt settings while the called party is busy, the additional information stored in the additional information storage area is searched from the caller's telephone number, and the called party Displayed on the subscriber additional information display section of the side telephone, when the called party operates the interrupt permission selection button and selects interruption possible, the called party, the subscriber who is currently talking with this called party, and the calling party are displayed. control means for connecting the three parties via a three-party call trunk.

[Function 1: When the caller requests interrupt settings, additional information about the caller is displayed on the called party's telephone, and the called party who sees this additional information presses the interrupt enable/disable selection button on the telephone. If you select "Interruption enabled" by operating , set the interrupt, and if the called party selects "Interruption refusal" by operating the "Interruption permission selection button", the interruption call will be rejected. To eliminate troubles between callers that occur when an interrupt call is established.

[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 automatic exchange with a function of selecting whether or not mutual extension interrupts can be interrupted according to the present invention, and FIG. 2 is an external view showing the telephones 1, 2, and 3 of FIG. 1.

This embodiment houses a telephone 1, 2.3 having a subscriber information display section 14 and an interrupt enable/disable selection button 13, and a main memory 9 including an additional information storage area 11 and a call status table storage area 12; It has a central control unit 8, a three-way trunk 10, a main switch 7 and subscriber circuits 4, 5.6.

The subscriber additional information display section 14 displays additional information, such as the subscriber's affiliation and name, which, when displayed on the telephone of the called party, allows the called party to select whether or not to accept an interruption from the caller. Is displayed. Additional information storage area 11 stores additional information of subscribers corresponding to telephone numbers.

Next, the operation of this embodiment will be explained.

Assume that telephones 2 and 3 are currently talking. Phone 1 is phone 2
When the user dials the extension number "102", the central control unit 8 performs call processing and connection processing. At this time, since the telephone 2 is busy, a busy tone is sent to the calling party's telephone 1.

When the calling side telephone 1 learns from the busy tone that the called side telephone 2 is busy and dials a special number requesting interrupt setting, an interrupt request signal 15 is sent from the telephone 1 to the central control unit 8.
sent to. Upon receiving the interrupt request signal 15, the central control unit 8 retrieves the telephone number "4" of the calling party telephone 1 that sent the interrupt request signal 15, which is stored in the additional information storage area 11.
The additional information 16 corresponding to "83" is searched and read from the telephone number "483", and the additional information 16 of the calling party is displayed on the subscriber additional information display section 14 of the called telephone 2 via the subscriber circuit 5.
, for example, "483 Kensagoto" (extension phone number, 0 affiliations, last name) is displayed to notify the called telephone 2 that an interruption request has been made. When the called party sees this additional information 16 and determines that it is OK to make an interrupt call if this is the other party, and selects interrupt possible by operating the interrupt enable/disable selection button 13 on the telephone 2, the called party can interrupt the call. An enable signal 17 is sent via the subscriber circuit 5 to the central control unit 8 .

Upon receiving the interrupt enable signal 17, the central control unit 8 connects the telephones 2, 3, and 1 via the three-way call trunk 10 to enable the interrupt call. At the same time as this connection is made, the central control unit 8 stores in the call status table storage area 12 the extension telephone number "483" of the telephone 1 that made the interruption.
Write the phone numbers of telephones 2 and 3 in response to .

The subscriber of the called telephone 2 sees the additional information 16 mentioned above and decides that he/she wishes to refuse the interruption, and presses the interruption permission/denial selection button 13.
If you select to refuse interruption by operating , three-party trunk 1
0 is not established, the interrupt call from telephone 1 can be rejected, and the interrupt call is no longer established.

[Effects of the Invention] As explained above, the present invention displays additional information of the calling party on the telephone of the called party when the calling party requests interrupt setting, and the called party who sees this additional information When the caller operates the interrupt enable/disable selection button on the telephone and selects the interrupt setting, the trouble between callers that occurs when a call is forcibly established can be eliminated by setting the interrupt. .
