Abstract

PURPOSE:To simplify the operation and to improve the convenience by storing a tentative call restriction class. CONSTITUTION:When a function button (a button of tentative conversion function of call restriction class of extension) of an attendant hoard 2 while an extension telephone set 1 and the attendant board 2 are busy, a CPU 4 receives the information, identifies the telephone set 1 busy with the attendant hoard 2 and a 2nd storage device 5 corresponding to the extension telephone set 1 changes the tentative class memory into a trunk line call enable class. Moreover, the attendant board 2 is in idle state, the extension telephone set 1 dials a trunk dial special number and when a tentative class is set, it is read from a storage device 5. When the readout class is disabled of trunk line dialing, a restriction tone is sent to terminate the processing. Thus, the tentative class between the attendant board 2 and the extension telephone set busy therewith is revised by the operation of the attendant board 2 to simplify the operation and to improve the convenience.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an electronic exchange that has a call restriction class for each extension and is capable of temporarily changing this call restriction class, and particularly relates to Concerning easy electronic exchanges.

[Prior Art] Electronic exchanges are used that store call restriction classes for each extension and restrict calls from the extension to the central office line in accordance with the class.

This call restriction class is set at the time of setting the call period, but it can be changed, especially if it has to be changed temporarily. I was able to change the calling restriction class for that extension phone.

[ff, d to be solved] The above-mentioned conventional electronic exchange temporarily changes the calling restriction class of the extension telephone by manually inputting a specific PIN number from the extension telephone, but the operation method is complicated and it is difficult to use. There was also the problem that it was difficult to maintain the confidentiality of the personal identification number entered manually.

The present invention was made in view of the above problems, and when temporarily changing the calling restriction class of an extension telephone,
To provide an electronic exchange that is easy to operate and requires little trouble in maintaining confidentiality.

[Means for Solving the Problems] In order to achieve the above object, the electronic exchange of the present invention includes a plurality of extension telephones, an exchange that accommodates the extension telephones and central office lines and performs line switching connections, and a switching and connection system in the exchange. In an electronic exchange that is equipped with a control means for controlling the above, and a relay board for instructing switching connection of the exchange, and has a call restriction class for each extension telephone, the control means is configured to control the call restriction class in normal times. This configuration includes a first restriction class storage means for storing temporary transmission restriction classes, and a second restriction class storage means for storing temporary transmission restriction classes.

Under such a configuration, in order to temporarily change the outgoing call restriction class, the second restriction class is temporarily stored in the extension telephone connected to the relay stand in response to an instruction from the relay stand. The transmission restriction class accumulated in the means is applied.

[Example] Hereinafter, the present invention will be explained in detail based on the drawings.

FIG. 1 is a flowchart showing the processing procedure when calling a central office line in an electronic exchange according to an embodiment of the present invention, FIG. 2 is a relay system diagram showing a schematic configuration, and FIGS. 3 and 4 are memory diagrams showing a memory configuration. FIG.

First, the general configuration will be explained.

In Fig. 2, 1 is the housed extension telephone (STA)
, 2 is a relay stand (ATT) that instructs various switching controls, 3 is a switch (SW) that switches connections between extension lines and central office lines, and 4
is a central control device (hereinafter referred to as CP) that controls the connection of exchange 3.
), 5 is a record 1 that stores the calling restriction class etc. of each extension! equipment (MEM). Further, as shown in detail in FIGS. 3 and 4, this storage device 5 is temporarily connected to a first storage device 5a that stores the normal calling restriction class (fixed class) regarding the calling restriction class of the extension line. It has a second storage vfl 5b for storing a call restriction class (-time class).

In the above configuration, when the extension telephone l and the relay console 2 are in a conversation state, the person handling the relay console 2 presses the function button installed on the relay console 2 (temporarily converts the calling restriction class of the extension). When the function button) is pressed, the information is sent to the CPU 4.

When the CPU 4 receives this information, it identifies the extension telephone 1 that is currently communicating with the relay stand 2, and changes the temporary class memory in the second storage device corresponding to the extension 1 to a class that allows calls to the central office line. In addition, relay console 2 is left vacant, and when extension 1 dials the central office line dialing special number,
Control is executed according to the flowchart shown in the figure.

In this process, when the extension telephone 1 dials the central office line calling special number (step 10), it is determined whether a temporary callback is set (step 12). If the determination is No, the fixed class of the storage device 5a shown in FIG.
Step 16) of reading the temporary class of the storage device 5b shown in the figure.

Next, it is determined whether the class that has been read is capable of making a call on the local line (Step 18). If it is determined as YES, the call is made on the local line (Step 20), but if it is determined as No, a restriction sound is sent out (Step 20).
Step 22) End the process.

Therefore, after pressing down the relay console 20 function button, the temporary class has been set, so the judgment in step 12 is YES, the temporary class is read out, and the read temporary class is used to transmit the central office line. Since this is possible, step 20 is executed to allow the central office line call based on the determination in step 18.

Note that the temporary error will be canceled when the extension telephone 1 is restored.

[Effects of the Invention] As explained above, the present invention simplifies the operation of the extension telephone and improves convenience, since it is possible to temporarily change the class of the extension telephone that is in communication with the attendant console by operating the attendant console. This has the effect that it is possible to provide an electronic exchange that can improve the performance.

In addition, since the information is performed by the person handling the relay stand, it is easy to maintain confidentiality.
