Abstract

PURPOSE:To efficiently use terminals by automatically calling a general subscriber from an external host computer without an originating terminal to eliminate the restriction time of call from the originating terminal to the general subscriber. CONSTITUTION:Information of a general subscriber 5 to be called is transmitted to a central controller 6 by a host computer 7, and the subscriber 5 is called based on this information. The device 6 confirms the response to connect the subscriber 5 and an announcement trunk 3. In this case, the device 6 informs the host 7 that the subscriber responds. Then, the host 7 gives information of an extension subscriber 2 to the device 6 to disconnect the subscriber 5 and the trunk 3, and subscribers 2 and 5 are connected based on information received from the host 7. Thus, the restriction time of call from the originating terminal to the general subscriber is eliminates to efficiently use terminals.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an outgoing connection system for an electronic exchange, and more particularly to an automatic outgoing connection system in an electronic exchange having an interface function with an external host 1 to a computer.

[Conventional technology]

In traditional outgoing connection methods, the extension subscriber goes off-hook and
A call was being made to a general subscriber on the called side while the caller was in a busy state.

[Problem to be solved by the invention]

In the conventional outgoing connection method described above, when a general subscriber is called from a reception desk terminal that receives many incoming calls, the calling party receives the call.
This has the drawback that the terminal becomes busy and cannot respond to incoming calls, resulting in poor efficiency.

[Means to solve the problem]

The automatic originating connection method of the present invention includes means for receiving connection request information of a general subscriber on the called side transmitted from the host computer to an electronic exchange having an interface function with an external host computer, and a means for receiving the connection request information. means for automatically calling the general subscriber without a terminal on the calling side; means for notifying the host computer of a response when the general subscriber responds; and communication between the general subscriber and an announcement trunk. means for receiving connection request information of a calling extension subscriber transmitted from the host computer; means for connecting the general subscriber and the extension subscriber based on connection request information of the subscriber, and storing information of the general subscriber who requests the host computer for automatic outgoing connection in a database; , means for searching necessary information from the database based on specified information and transmitting it to the electronic exchange; means for receiving a response notification from the general subscriber from the electronic exchange; and receiving the response notification. This configuration further includes means for transmitting information on the extension subscriber to be connected to the general subscriber to the electronic exchange when the general subscriber is connected.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

1, 2, and 3 are relay system diagrams showing an embodiment of the present invention, in which FIG. 1 shows the called party while the called party is ringing, FIG. 2 shows the called party and the announcement trunk connected to the called party, and FIG. FIG. 3 shows the state in which the called party and the extension subscriber are talking, respectively. Also,
FIG. 4 shows the sequence of transmission and reception of control information between the central control unit of the electronic exchange and the host computer.

Referring to each figure, the host computer 7 sends information about the called general subscriber 5 to the central control device 6 (fourth
a) in the figure. Based on this information, the central control device 6 calls the general subscriber 5 (b in FIG. 4). In Figure 2,
When the central control device 6 confirms the response from the general subscriber 5, it connects the general subscriber 5 and the announcement trunk 3. At that time, the central control device 6 notifies the host 1 to the computer 7 that the general subscriber 5 has responded (the fourth
c, d) in the figure. Next, in Figure 3, general subscriber 5
In response to the notification of the response, the host I/computer 7 transmits information about the extension subscriber 2 to the central control unit 6 (e in FIG. 4). The central control unit 6 disconnects the general subscriber 5 from the announcer T-1 rank 3, and connects the extension subscriber 2 to the general subscriber 5 based on the information received from the post computer 7.

1' Effects of the Invention] As explained above, according to the present invention, by automatically calling a general subscriber to an external host combination 1-evening without a calling terminal, the calling terminal can call the general subscriber. You can use the terminal more efficiently by eliminating the time constraints of calling.
