Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extension terminal control device for a private automatic branch exchange.

[0002]

2. Description of the Related Art Conventionally, a private automatic branch exchange has accommodated several extension lines in a single extension terminal control unit and has increased the expandability by using this as a unit for extension of lines. In addition, the call processing unit performs only logical switching processing, and the input / output control of the extension terminal is performed by the extension terminal control device to reduce the load on the call processing unit and improve the processing capacity of the entire private automatic branch exchange. There is.

FIG. 3 is a functional block diagram when two extension terminals are connected to a conventional extension terminal control device. Reference numeral 13 is a call processing unit, 21 is an extension terminal control device, and 22 and 23 are extension terminals.

When the call processing unit 13 outputs the lamps or bells of the extension terminals 22 and 23, the communication control unit 1
4, the output message to which the numbers of the extension terminals 22 and 23 are added is transmitted to the output control units 15 and 18, and the output control units 15 and 18 convert this message into the output message format of the extension terminals 22 and 23 to control the communication. The units 17 and 20 are used to send a message to the extension terminal and output it. Further, the input messages received from the communication control units 17 and 20 such as pressing the buttons of the extension terminals 22 and 23 are added with the numbers of the extension terminals 22 and 23 by the input control units 16 and 19, and the communication control unit 14 calls the call processing unit. Send to 13.

[0005]

However, in the above-mentioned conventional configuration, a telephone is used as the extension terminal 22 and an operation panel having an extension direct call button is used as the extension terminal 23. When using the call processing unit 13, the call processing unit 13 must read the button press message from the operation panel as a message from the extension telephone and process it, resulting in an increase in the load of the call processing unit 13. Also,
A terminal having a plurality of digital input / output ports is accommodated as the extension terminal 23, and only one of the terminals is used as the extension terminal 2
When used as an input / output port of No. 2, the call processing unit 13 must manage the port of the extension terminal and the extension telephone number that uses the port, which causes a large load other than the logical exchange process. Had.

An object of the present invention is to solve the above problems and an object of the present invention is to provide an extension terminal control device capable of freely configuring an extension terminal without increasing the load on a call processing unit.

[0007]

In order to achieve the above object, the present invention provides, as an extension control device, means for combining input / output devices provided in a plurality of extension terminals and processing them as one logical virtual terminal. When the call processing unit instructs the virtual terminal to output the virtual terminal, the extension terminal control device outputs the virtual terminal to the actual terminal to which the virtual terminal output device is assigned. The terminal control device converts the input device into a virtual terminal number to which the input device is assigned and notifies the call processing unit of the number.

[0008]

According to the present invention, with the above-described configuration, the call processing unit only issues an output instruction to the extension control device that controls the virtual terminal, and the extension terminal control device performs the output to the actual terminal. When receiving a message with a virtual terminal number added from the input, the message is processed only with the virtual terminal number for both output and input, so that an extra load due to message rereading in the call processing unit does not occur. To do.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram when two extension terminals are connected to an extension terminal control device according to an embodiment of the present invention. In FIG. 1, 1 is a call processing unit for performing a logical exchange process, 10 is an extension terminal control device according to an embodiment of the present invention, and 11 and 12 are extension terminals. The virtual terminal control unit 3 manages the input / output resource used for each virtual terminal recognized by the call processing unit 1 and the number of the extension terminal having the resource. The real terminal control units 4 and 7 create an output message of the extension terminal according to an instruction from the virtual terminal control unit, and transmit the output message to the extension terminal via the communication control units 6 and 9. Further, the resource allocation management units 5 and 8 manage the input resource number of the extension terminal and the virtual terminal number using the resource.

Next, FIG. 2 shows a procedure when the extension terminals 11 and 12 are combined and used as one virtual terminal 11. Here, consider a case where a telephone having a button with a lamp is used as the extension terminal 11 and an operation panel having a plurality of buttons with a lamp is used as the extension terminal 12.
First, the extension terminal 11 that has detected the button press notifies the resource allocation management unit 5 of the button press information (24). The resource allocation management unit 5 determines the virtual terminal number 11 using the corresponding button.
Is added to the button press information and notified to the call processing unit 1 (2
5). The call processing unit 1 transmits the lamp display message of the pressed button to the virtual terminal control unit 3 (26). The virtual terminal control unit 3 determines that the lamp is a resource of the extension terminal 11 and sends a lamp display message to the corresponding real terminal control unit 4 (27). Upon receiving the message, the real terminal control unit 4 converts this message into a lamp display message corresponding to the extension terminal, transmits it to the extension terminal 11, and lights the lamp of the pressed button (28). On the other hand, when the button of the extension terminal 12 is pressed, the same procedure is performed (29), but the resource allocation management unit 8 adds the virtual terminal number 11 to the button pressing information and transmits it to the call processing unit 1. (30), the call processing unit 1 determines that this is a button press from the virtual terminal 11, and sends a corresponding lamp display message to the virtual terminal control unit 3 that controls the virtual terminal 11 (31). In the virtual terminal control unit 3, the corresponding lamp is the extension terminal 1
It is determined that the resource is the second resource, and the lamp display message is transmitted to the corresponding real terminal control unit 7 (32). Similar to the real terminal control unit 4, the real terminal control unit 7 sends a message to the extension terminal 12 and turns on the lamp of the pressed button (33).

As described above, according to the present embodiment, the virtual terminal controller that refers to the real terminal number in which the resource exists from the output resource number of the virtual terminal and the resource is used from the input resource number of the real terminal. Since the virtual terminal and the real terminal are associated with each other by providing the real terminal control unit that refers to the terminal number of the virtual terminal, the call processing unit is not overloaded.

[0012]

As is apparent from the above embodiments, according to the present invention, when the input / output resources of a plurality of terminals are controlled as a single terminal, the extension terminal control device is a logical virtual terminal and a real terminal. Correspondence is performed and the call processing unit only needs to instruct the virtual terminal number, so that no extra load occurs. Therefore, it is possible to freely configure the extension terminal without imposing a load on the call processing unit, and it is possible to provide the extension terminal profession apparatus that improves the extension service.
