Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone exchange device having a transmission restriction system and a transmission restriction function in a telephone exchange device such as a key telephone device and a private branch exchange device.

[0002]

2. Description of the Related Art In a telephone exchange apparatus, a control system is known in which, when a call is made from an extension line to an outside line, an outside line call is prohibited depending on a calling point. This control is called a call restriction control.

In the conventional call restriction control, a call restriction class (hereinafter referred to as a class) is set for each type of call restriction (for example, a class that prohibits all outside line calls, a class that prohibits out-of-town calls, and a foreign country). , A class that prohibits outgoing calls, a class that allows outgoing calls to all outside lines, etc.), or any class for all extension lines.
Further, in the key telephone device, since the outside line can be selected from the telephone, the class is also given to the outside line.

[0004]

As described above, since the class is assigned to the conventional extension line or outside line,
For example, if a person who is allowed to make a call to a foreign country by the class of the phone assigned to him / her uses another phone, if the class of the other phone is a class that prohibits making a call to a foreign country, There is a problem that people cannot call abroad.

This problem arises from the fact that transmission restrictions are set for internal or external lines.
It is an object of the present invention to obtain a new call regulation system that enables the call regulation on a person-by-person basis and a telephone exchange device having a call regulation function by this system.

[0006]

In order to solve the above problems, the present invention sets a second class corresponding to an ID code assigned to each person in addition to the class set for extension extension. , When the ID code is input from the telephone of the extension, the class of the extension is converted from the class assigned to the extension to the class corresponding to the ID code. More specifically, Is extension restriction class information for the extension (hereinafter referred to as class information).
, A second table storing class information corresponding to the ID code, and a class information corresponding to the originating extension from the class information in the first table when a call is originated from the extension. First class information identifying means for identifying, storage means for storing the class information identified by the first class information identifying means together with outgoing extension information, and when the ID code is input from the outgoing extension, the second class information identifying means Second class information identifying means for identifying the class information corresponding to the ID code from the class information in the table, and when the class information is identified by the second class information identifying means, the class information is stored in the storage means. Class information changing means for rewriting the existing class information to the class information identified by the second class information identifying means, and the class information stored in the storage means. Based on, and transmission regulation means for call restriction control of the originating internal, in which as provided in the telephone exchange apparatus.

[0007]

[Operation] By entering the ID code when making a call,
Since the class set for extension is changed to the class for ID code, the caller can make a call to the area within the range approved by himself from any extension (telephone).

And a CPU that collectively controls the telephone exchange PBX.
4 and a memory 5 storing or storing information necessary for control processing in the CPU 4.

The memory 5 has areas allocated to the first table TA1, the second table TA2 and the state storage memory M, and the first table TA1 is shown in FIG. So that each extension S1 to Sn
Class information A, B, C ...
Are stored in advance, and the second table TA2 is shown in FIG.
As shown in (B), each ID code ID1, ID2, ...
Class information A, B, C ...
Is stored in advance. The state storage memory M includes telephones TEL1 to TELn (extension lines S1 to Sn) and an outside line L.
Various states from 1 to Lm (for example, outgoing state, incoming state, etc.)
A memory for storing and monitoring
An area for storing outgoing extension information is related, and in this area, as shown in FIG. 2 (C), information of the extension that has made the outgoing call (outgoing extension information) and class information thereof are provided every time the outgoing call occurs. Are configured to be stored in association with each other.

Various means necessary for carrying out the present invention are obtained by the CPU 4. That is, the transmission extension is detected, and the class information given to the transmission extension is stored in the memory 5
Means for identifying based on the stored information in the first table TA1 (first class information identifying means), means for storing the class information identified by the means together with outgoing extension information (storage means), and an ID code from the outgoing extension. When there is an input, there is a means for identifying the class information corresponding to the ID code based on the stored information in the second table TA2 of the memory 5 (second class information identifying means), and the identification of the class information by the means. In this case, the class information (class information corresponding to the extension) stored in the storage unit is rewritten to the newly identified class information (class information corresponding to the ID code) (class information changing unit), the storage unit. The means for controlling transmission control based on the class information stored in the means (transmission control means) and the like are realized by the program control of the CPU 4.

The classes assigned to the extensions S1, S2, S3 are A, C and B, respectively, and ID codes ID1, ID2.
The operation will be described below with reference to FIG. 3 assuming that the classes corresponding to ID3 are A, B, and C, respectively. Note that classes A, B, and C are set in this order from higher to lower (as they go higher,
It is assumed that transmission to a wider area is allowed. ).

The classes corresponding to the extensions S1 to Sn and the classes corresponding to the ID codes ID1, ID2 ... Are telephones TEL1 to TEL1.
Of the TELn, the data is input using a telephone (usually a key telephone) used as a data input device, which is set in advance, and the first table TA1 and the second table TA1 are set.
The table TA2 stores the class information as shown in FIGS. 2A and 2B, respectively, by inputting the above data. The data input may be performed by a data input dedicated terminal.

The CPU 4 constantly monitors the states of the extensions S1 to Sn via the extension circuits 11 to 1n, and this state monitoring includes call origination monitoring.

Now, if it is assumed that the telephone TEL2 is used to perform a calling operation (such as an operation to lift the handset), the CPU
4 identifies that the extension S2 is in the calling state via the extension circuit 12 (step S1), and stores the calling extension information "S2" in the state storage memory M of the memory 5 (step S).
2).

Next, the CPU 4 identifies the class information "C" corresponding to the transmission extension S2 by referring to the first table TA1 of the memory 5 (step S3), and as shown in FIG. The class information “C” is stored in the state storage memory M
Then, it is stored in association with the already stored outgoing extension information "S2" (step S4). The information stored in the state identification memory M shown in FIG. 2C indicates that the extension Sn (telephone TELn) is already in the calling state at this point.

With the above control, the telephone exchange apparatus PBX can accept dial information from the telephone TEL2.
The CPU 4 sends a dial tone from the signal source (not shown) to the telephone TEL2 via the extension circuit S2 (step S5).

Next, the CPU 4 monitors the input of dial information from the telephone TEL 2, and when the dial information is input, the dial information is the ID code or the destination code (callee telephone number). ) Is determined (steps S6 and S7).

Now, to the person who makes a call from the telephone TEL2, I
D code ID1 is assigned and the ID code ID
It is assumed that 1 allows transmission within the class A range. The caller from the telephone TEL2 is
Normally, the call cannot be made to an area other than the range of the class C assigned to the extension S2. Therefore, when making a call to an area within the range of class A outside the range of class C, the telephone set TE
The ID code ID1 assigned to itself by L2 is transmitted from L2.

When the ID code ID1 is sent from the telephone TEL2, the CPU 4 sends the ID code through the extension circuit 12.
The code ID1 is read and the second table TA in the memory 5 is read.
2, the class information "A" corresponding to the ID code ID1 is identified (step 7), and the class information "C" stored together with the extension information "S2" transmitted to the state storage memory M is added to the class information. It is rewritten to "A" (step S9), and then waits until the destination code sent from the telephone TEL2 is input up to a digit at which transmission restriction can be judged (step S10).

When the destination code is input without inputting the ID code, it goes without saying that steps S8 and S9 are not performed and the above step S10 is performed.
Control is advanced to (YES step in step S7).

When the destination code is input from the telephone TEL2 to a predetermined number of digits, the CPU 4 causes the state storage memory M
Class information (“A” when the ID code ID1 is input, “C” when the ID code ID1 is not input) corresponding to the extension S2 stored in (1) is compared with the destination code (step S11), It is determined whether or not the call from the extension code to the subscriber from the extension S2 is permitted (step S1).
2).

The destination code is the class information "A".
Or, if it indicates the area defined by "C", C
The PU 4 captures an empty outside line circuit, for example, the outside line circuit 21 (the destination code indicates that the outside line is transmitted), and controls a dial sender (not shown) to send a dial signal corresponding to the destination code to the outside line. It is sent to L1 (step S13).

If the destination code indicates an area other than the area defined by the class information "A" or "C", the CPU 4 sends a busy tone from a signal source (not shown) to the extension circuit. It is sent to the telephone TEL2 via 12 (step S14).

At the end of the call, the stored information in the state storage memory M disappears, and the class of the transmission extension S2 is the first table T.
It will return to the class C defined by A1.

[0027]

As described above, according to the present invention, in addition to the call restriction class assigned for each extension, the call restriction class assigned for each person is set and the ID code is dialed from the telephone. , The code assigned to the extension to which the telephone is connected can be changed to the class corresponding to the above ID code (class assigned to each person), and the code of the telephone (extension) used when making a call Even if the class is lower than the class assigned to the caller, the caller can make a call to an area within the range permitted by the caller.
