Abstract

PURPOSE:To allow a telephone set terminal itself to restrict dialing by providing a terminal control circuit by discriminating whether or not an input number is allowed of dialing when dial input is made for dialing based on information of a storage device and executing the dialing processing only when the dialing is allowed. CONSTITUTION:Whether or not dial input of a required digit number is finished is discriminated at first and when the dial input is finished, whether or not a high-order 2-digit of a station number to be dialed is an object of dialing restriction is checked based on information of a storage device 2 and when the digit is not object of restriction, the dialing is allowed. However, the high- order 2-digit of a station number to be dialed is an object of dialing restriction, whether or not numbers of 3rd and succeeding digits to be dialed are coincident with the number of enable dialing is checked based on the information in the storage device 2 and when dissident, the restriction of dialing is informed to a caller by a display circuit 3 or a speaker 5 at the point of time of the detection to terminate the dialing forcibly.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field 1] The present invention relates to a telephone terminal (including a telephone and a terminal device that transmits and receives data using a telephone line).

[Prior art] Telephone terminals are connected directly or via a private branch exchange (PBX).
It is connected to the lines of NTT (Nippon Telegraph and Telephone Corporation), etc., and is used for private or business communications.

For such telephone terminals, especially those installed for business use, it may be desirable to restrict outgoing calls in order to prevent unauthorized use.

However, conventional telephone terminals do not have a function that makes it possible to restrict outgoing calls as a standalone device.

[Problems to be Solved by the Invention] Therefore, in a configuration in which a business telephone terminal is directly connected to a line of NTT or the like, there is a problem in that it is impossible to restrict outgoing calls even if desired.

On the other hand, in a configuration in which telephone terminals are connected to lines such as NTT via a private branch exchange, calling restrictions can be set for each extension by setting various conditions for calling restrictions in the control circuit inside the private branch exchange. However, there is a problem in that the operations for setting conditions for restricting outgoing calls are generally complicated and troublesome.

There is also the problem that the traffic in the private branch exchange decreases because it is determined whether or not calls are subject to call restrictions.

The present invention has been made in view of the above circumstances, and even if the telephone terminal is directly connected to the line of NTT etc.
It is possible to restrict outgoing calls to lines such as T, and
In cases where telephone terminals are connected to lines such as NTT via a private branch exchange, etc., it is possible to simplify the operation of setting various conditions for calling restrictions on the private branch exchange, and to reduce traffic at the private branch exchange, etc. The purpose is to provide a telephone terminal that can prevent

[Means for Solving the Problems] The telephone terminal according to claim 1 includes a judgment information input means for inputting information for judging whether or not to permit a call, and a judgment information input means for inputting information for judging whether or not to permit a call, and information input from the judgment information input means. A storage device that stores information, and when a dial is input for making a call, it is determined based on the information in the storage device whether or not the input number is permitted to make a call, and the call is permitted. The device is characterized in that it includes a terminal control circuit that executes the outgoing call process only when the call is made.

Further, the telephone terminal according to claim 2 is the telephone terminal according to claim 1, further comprising a private branch exchange connection mode used when connecting to an extension of a private branch exchange, and
The judgment information input means is characterized in that it is possible to input a number to capture the central office line of the private branch exchange and to set whether or not it is possible to make a central office line call to the private branch exchange.

[Operations] The telephone terminal according to the present invention can restrict outgoing calls by itself.

Therefore, even if a telephone terminal is directly connected to an NTT line, it is possible to restrict outgoing calls to the NTT line.
In the case of a configuration connected to a line such as TT, it is possible to simplify the operation of setting various conditions for call regulation in a private branch exchange, etc., and also prevent a drop in traffic in the private branch exchange, etc.

[Example] A telephone terminal according to an embodiment of the present invention will be described below.

The telephone terminal in one embodiment is a so-called telephone set, and includes a telephone body and a handset connected to the telephone body.

As shown in FIG. 1, the telephone main body of this embodiment includes a judgment information input means 1 for inputting information for judging whether or not to permit a call, and the judgment information input means 1.
a storage device 2 for storing information input from the input means 1; a display circuit 3 for displaying information input from the input means 1 and the current status of the telephone terminal; A tone generating circuit 4 that generates a confirmation tone signal and a busy tone signal, a speaker 5 that reproduces the tone signal generated by the tone generating circuit 4, and a speaker 5 that controls the call (such as connecting a path with a handset and a handset). A line/line that interposes between the call control circuit 6, the telephone network (line) 7, and the call control circuit 6 to capture and release the line, and send out dial signals.
It is equipped with a dial control circuit 8 and a terminal control circuit 9 that controls the entire terminal.

The judgment information input means 1 includes a numeral 10 for inputting numbers.
Types of keys (“O”, “Bill”, , , , , 11
9 keys) and multiple function keys. and,
The function keys include a registration key for setting the registration mode and a registration end key for notifying the end of data input in the registration mode.

Such judgment information input means 1 is also used as an input section for a subscriber number to be called.

The "information for determining whether or not to permit outgoing calls" inputted from this judgment information input means 1 includes (a) station number to be restricted from calling, (b) calling permission number, and (c) private branch exchange connection mode setting. information, (d) central line collection number, and (e) central line calling regulation setting information.

As the area number for which calling is restricted in (a) above, the upper two digits of the relevant area code (usually the area code) are input.

Furthermore, the maximum number of call restriction station numbers that can be registered in the storage device 2 is 10 (from 00 to 09). This arrangement was made in order to simplify the registration process.
This is because rough regional regulations can be made using two digits.

If the calling permission number in (b) above is restricted to two digits as in (b) above, the restriction may be too broad and lead to deficiencies (for example, some subscribers whose dialing area numbers are restricted, This method was adopted in order to prevent such defects from occurring (such as when a subscriber who should be allowed to make a call is included).

The call permission number is a (X-3) digit number from the third to the Xth digit of the subscriber number (including area code) that is dialed in when making a call, and can be registered in the storage device 2. The number is set to a maximum of Y (X and Y can be arbitrarily set depending on the capacity of the storage device 2, etc.).

The private branch exchange connection mode setting information in (c) above is used when the telephone terminal is connected to the extension of the private branch exchange.
This information is used to set the "private branch exchange connection mode" on the telephone terminal in advance, and in this embodiment, it can be input by pressing a specific key on the input means 1.

The private branch exchange connection mode is set by setting the input state of the input means 1 to the private branch exchange connection mode registration mode and inputting certain data (private branch exchange connection mode setting information).

In this embodiment, the private branch exchange connection mode is set by pressing a specific key on the input means 1, but the method of setting the private branch exchange connection mode is limited to the method of this embodiment. Instead, various known techniques can be used, such as mode switching using a dip switch or a method using software.

The central office line acquisition number in (d) above is the number (usually number 0゛°) used to acquire the central office line of the private branch exchange when the telephone terminal is connected to the extension of the private branch exchange. be.

If the private branch exchange connection mode described above is set and a central office line acquisition number is also set (input), the central office line acquisition number will be automatically added to the beginning of the dialed number (or preset dial). This eliminates the need to dial in the central office line acquisition number each time you make a call.

The above (e) central line call restriction setting information is information indicating whether or not central line call restriction is applied to calls from the telephone terminal when the telephone terminal is connected to an extension of a private branch exchange. In this embodiment, input can be made by pressing a specific key on the input means 1.

In addition, in this embodiment, if a specific cow in the input means 1 is
Although the central line calling restriction is set by pressing , the setting method for the central line calling restriction is not limited to the method of this one embodiment, and there are other methods such as changing a dip switch or using software. , various known techniques can be used.

The above-mentioned information (a) to (e) are input by calling up the corresponding registration mode by pressing the registration key of the input means 1.

FIG. 2 shows the input procedure for each of the information (a) to (e) in this embodiment, together with the operations of the registration key and the registration end key.

That is, when the registration key is pressed once, input of "information for determining whether or not to permit a call" begins (step 100), and first, the call restriction station number is entered for inputting the information in (a) above. Registration mode is set (step 101)
).

Next, after inputting the information in (a), when the registration key is further pressed, a calling permission number registration mode for inputting the information in (b) is set (step 102).

Next, after inputting the information in (b), when the registration key is further pressed, the private branch exchange connection mode registration mode for inputting the information in (c) is set (step 103).
), then it is determined whether the private branch exchange connection mode has been set (step 104).

And if the private branch exchange connection mode is set,
Automatically, first, the station line acquisition number registration mode for inputting the information (d) above is set (step 105).
, (d), the central office line transmission regulation registration mode for inputting the information (e) is further set (step 106).

Next, press the registration end key (step 107)
, the input of "information for determining whether or not to permit the outgoing call" is completed (step 108).

Note that if the private branch exchange connection mode is not set in step 103, mote', step 1 is immediately executed.
Proceed to 07.

Further, each registration mode shown in steps 101 to 106 described above is set in order in a scrolling manner, and when the registration end key is pressed, the order changes to the first calling regulation station number registration mode. return.

The storage device 2 uses a RAM, and stores various information input from the input means 1 based on instructions from the terminal control circuit 9.

The display circuit 3 is composed of an LCD or the like, and displays information input from the input means 1, the current operating state of the telephone terminal, etc. based on commands from the terminal control circuit 9.

The terminal control circuit 9 is composed of a CPU, ROM, and PIO, and controls the operations of the aforementioned storage device 2, display circuit 3, tone generation circuit 4, line/dial control circuit 8, etc.
When a dial is input to make a call, it is determined based on the information in the storage device 2 whether or not the input number is permitted to make a call, and only if the number is permitted to make a call. Executes outgoing processing.

The call restriction processing in the terminal control circuit 9 will be explained based on FIGS. 3 and 4.

FIG. 3 shows the process when the telephone terminal of the above embodiment is directly connected to a line such as NTT (that is, when the above-mentioned private branch exchange connection mode is released).

First, it is determined whether or not the required number of digits have been dialed (step 20+), and if the dialing has been completed, based on the information in the storage device 2, it is determined whether or not the dialed number has been input.
A check is made to see if the two digits in the - place are subject to call restriction (step 202), and if not, dialing is permitted (step 203).

However, if the third two digits of the dialed area number are subject to restrictions, based on the information in the storage device 2, the numbers from the third digit onward of the dialed number are subject to restrictions. Check if it matches the number Step 2
04) If they match, the process proceeds to step 203 and the call is permitted, but if they do not match, as soon as it is detected, the display circuit 3 or the speaker 5 indicates to the caller that the call is restricted. and forcibly terminates the call (step 205).

In other words, the calling permission number has an advantage over the calling restriction area code, and even if the area code of the phone number you want to make a call is subject to calling restrictions, if it is registered as the calling permission number, the call will not be accepted. is allowed.

Note that the time point at which step 202 is started differs depending on whether the calling method is a preset dial or a normal dial input.

In the case of preset dialing, step 202 starts when all the dialed numbers have been entered, whereas in the case of normal dialing, the top two of the station numbers are entered.
Step 202 begins when the input of digits is completed.

FIG. 4 shows a case where the telephone terminal of the above embodiment is connected to a line such as NTT via a private branch exchange (i.e.,
This is the process when the above-mentioned private branch exchange connection mode is set).

First, it is determined whether or not dialing of the required number of digits has been completed (step 301), and if it has been completed, based on the information in the storage device 2, it is determined whether or not the dialing is from a central office line (i.e., from within the premises). 1. Determine whether the exchange connection mode is set or not.
(Step 302), if the call is not from a central office line (that is, if the call is from an extension), the call is immediately permitted (Step 3
o3).

If it is determined in step 302 that the call is from a central office line, it is determined based on the information in the storage device 2 whether or not a central line calling restriction is set (step 304), and the central line calling restriction is set. If it is detected, the display circuit 3 or speaker 5 notifies the caller that the call is restricted, and the call is forcibly terminated (step 305).

If the central office line calling restriction is not set, a check is performed to see if the first two digits of the dialed station number are subject to the calling restriction.

step 306), and if the device is not subject to regulation, the time cell call is permitted (step 303).

However, if the upper two digits of the dialed station number are subject to regulation, based on the information in the storage device 2,
Check whether the numbers from the 3rd digit onward of the dialed number match the dialing permission number (Step 3).
07) If they match, proceed to step 303 and allow the call, or if they do not match, as soon as it is detected, the display circuit 3 or the speaker 5 sends a message that the call is restricted. to forcefully terminate the outgoing call.

In other words, a spoofed number has an advantage over a dialing restriction area number, and even if the area code of the phone number you want to make a call to is subject to dialing restrictions, if it is registered as a number that is permitted to make a call, this number will be rejected. Outgoing calls are allowed.

Note that the point at which step 302 is started differs depending on whether the calling method is a preset dial or a normal dial input.

In the case of preset dialing, step 3'02 is started when all the dialed numbers have been entered.
On the other hand, in the case of normal manual dialing, step 302 is started when the input of the upper two digits of the station number is completed.

Note that if the telephone terminal is connected to an extension of a private branch exchange and a central office line acquisition number is dialed, all subsequent numbers except for that central office acquisition number are processed in step 306 and step 306. 307 processing target.
