Abstract

PURPOSE:To save labor for changing bell signal information by providing a variable data memory part at each extension key telephone system and on the other hand, providing a fixed data memory part at a main unit so as to store the plural bell signal information, separately from a program memory part. CONSTITUTION:A fixed data memory part 104 stores the plural bell signal information to determine a bell tone, ringing pattern and volume, etc., in advance. A variable data memory part 109 copies the plural bell signal information such as the bell tone, bell ringing pattern and bell volume, etc., to be stored in a main unit 100 and stores those information as the bell signal information. When a ringing request is generated to ring a bell at an extension key telephone system 105 with an incoming call, a bell transmission request processing is executed for each kind of a bell signal corresponding to the respective bell signal information in the variable data memory part 109. Thus, the variable data memory part can be designed at low cost so as to store one kind of bell signal activation information at least on the extension key telephone system.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an extension key telephone that controls the ringing of a bell signal of an extension key telephone connected to an extension of a main unit.

Conventional technology FIG. 7 is a block diagram of a conventional key telephone device.

700 is a main device; 704 is an extension telephone housed in each extension of the main device 700, that is, an extension key telephone; the main device 700 exchanges control data with each extension key telephone 704, makes calls, performs connection work, etc. In addition to implementing various other service functions. 7
11 is an extension communication line.

First, the configuration of main device 700 will be explained. A communication unit 703 is connected to the extension communication line 711 and sends and receives control requests and control responses to and from the communication unit 706 of the extension key telephone 704 . 701 is a control unit. The control unit 701 uses the communication unit 703 to send various signals to each extension telephone according to the operation program stored in the program storage unit 702 (shown as a flowchart in FIG. 8), and also controls the communication from each extension telephone. Controls the operation of each part by receiving various signals.

The one-way line button telephone 704 has the following functions. A communication unit 706 is connected by the extension communication line 711 and sends and receives control request signals and control response signals to and from the communication unit 703 of the main device 700. Also 7
08 includes bell signal information (a, b, . . . ) such as the tone of a plurality of bell signal ringing sounds, a bell ringing pattern, and a bell volume.
n.

m, etc.) is a fixed data storage unit in which data is stored in a fixed manner in advance. 709 is a D/A conversion amplification section, which converts the previous bell signal information into an analog signal on the amplitude axis or time axis,
The power is amplified. 710 is the D/A conversion section width section 7
This is a speaker that converts the 09 power signal into an audible sound signal. 7
Reference numeral 07 represents a program storage unit that stores the program shown in the flowchart of FIG. 9, and 705 represents a control unit that performs control operations based on the program stored in the program storage unit 707.

FIGS. 8 and 9 are flowcharts showing operating programs for main device 700 and extension key telephone 704, respectively.

In the flowchart of the main device 700 shown in FIG.
When it becomes necessary to ring a bell on the extension key telephone 704 due to an incoming call or the like (step 801), the process moves to step 802. In step 802, the requested bell ringing type is confirmed, and each bell signal information (a, b, . . . , m, Performs bell sending request processing corresponding to n). That is, from Bell (a) sending request processing (step 803) to Bell (n)
Out of the processes up to the transmission request process (step 804), a process appropriate for the requested bell ringing type is executed;
Through this processing, the communication unit 703 transmits a request signal to ring an appropriate bell signal.

In the flowchart of the extension key telephone 704 shown in FIG. 9, step 901 is a reception process for receiving various requests sent from the main device 700, and the next step 902 is a determination as to whether request reception is complete. Waiting for receiving a request in steps 901 and 902 is repeated. When the request signal is received in step 902, the process moves to step 903 and the content of the request is analyzed.

If the request is not related to ringing of a bell signal, the process jumps to step 908, but if the request is related to ringing of a bell signal, the process moves to the next determination of the type of ringing of the bell signal. In the bell signal ringing type determination in step 904, the bell signal information (a) in the fixed data storage section 708 is based on the received request signal.

b, . . . , n, m) is selected. For example, if the bell (a) is specified, step 905 is executed and the bell (a) is transmitted. In the case of (n), step 906 is executed. In step 907, a response is sent to the main device 700 to the effect that the bell signal activation has been completed. Then, the process moves to step 908, and after checking other received requests and controlling the start/stop of various operations, the process returns to step 901, and continues the standby state for receiving the various requests described above.

Problems to be Solved by the Invention By the way, some key telephone devices, if they are included in the same system, may change the operation program of the main device to an operation program with a new function, or the main device itself may change. Even if a telephone has been replaced with one with new functions, it is now possible to connect and use the extension telephones that were previously used as is.

It would also be very convenient if it were possible to distinguish the type of extension terminal from which the call was made, the route of the incoming call, etc. based on the type of bell sound, that is, the tone color and ringing pattern.

However, if you use this method, for example, if the main device itself is replaced with one with new functions several years after first use, and the number of extension terminal types and incoming call routes increases. As mentioned above, the bell signal information that determines the tone and ringing pattern, which was fixedly stored in the fixed data storage section 708, is no longer sufficient, and the user is unable to make full use of the newly added functions. Become.

It is also conceivable to change the bell signal information in each extension telephone as the main device is changed, but this requires a lot of effort. That is, it is necessary to replace all the program storage units and the fixed data storage units in which the bell signal information is written in the plurality of extension button telephones connected to the extension. In reality, these program stores and fixed data stores are generally integrated circuit chips called ROMs, and replacing the program stores and fixed data stores of each extension key telephone means that each extension key telephone's corresponding This means that each ROM must be replaced manually, which requires a great deal of effort in a system that accommodates a large number of extension key telephones.

Means for Solving the Problems In order to solve the above problems, the present invention provides each extension key telephone with a variable data storage section that can be rewritten at any time and has a capacity capable of storing a plurality of pieces of bell signal information. is equipped with a fixed data storage section that stores a plurality of pieces of bell signal information, and before using the bell signal, the plurality of bell signal information in digital format stored in the fixed data storage section on the main device side is stored in the extension line. The data is transferred and copied to the variable data storage unit in the key telephone via an extension communication line.

Effects With the above configuration, when a new bell signal is required due to the addition of a new service to the main device, if the fixed data storage unit that stores the bell signal information is replaced only in the main device, the new bell signal information after replacement can be obtained. is automatically transferred from the main device to the extension key telephone via the extension communication line and is also copied to the variable data storage section of the extension key telephone. The bell sound is generated based on the received bell signal information, and there is no need to change each extension key telephone.

EXAMPLE A first example of the present invention will be described below. FIG. 1 is a functional block diagram showing the configuration of the key telephone device in this embodiment. 100 is a main device; 105 is one of a plurality of extension button telephones connected to the main device 100;

In the main device 100, 102 is connected to the extension communication line 112 and transmits and receives control requests and control responses to and from the communication unit 107 of the extension key telephone 105, and 104 is used to control the bell tone, ringing pattern, volume, etc. Determine multiple bell signal information (A.

This is a fixed data storage unit that stores data (B, . . . , N, M) in advance. Reference numeral 103 is a program storage unit that stores an operating program (shown as a flowchart in FIG. 2).

Reference numeral 101 denotes a control unit that controls each unit according to an operation program stored in the program storage unit 103. Control part 1

N, M) to the extension key telephone 105 via the extension communication line 112.

The one-way edge button telephone 105 is constructed as follows.

107 is connected to the previous extension communication line 112, and the main device 1
00 communication unit 102 and control requests and III II
This is a communication unit that sends and receives various information such as T responses. 10
Reference numeral 9 denotes a variable data storage unit whose storage contents can be freely rewritten. The variable data storage unit 109 copies bell signal information (A, B, . . . , N, M) such as a plurality of bell tones, bell ringing patterns, and bell volumes stored in the main device 100, Bell signal information (a, b, ..., n, m
). Reference numeral 110 denotes a D/A converter width section 110 that converts the previous bell signal information into an analog signal on the amplitude axis or time axis and performs power amplification.

Reference numeral 111 denotes a speaker 111 that converts the output signal of the D/A converter width section 110 into an audible sound signal. Reference numeral 108 denotes a program storage unit that stores an operating program for the telephone set (shown as a flowchart in FIG. 3). Reference numeral 106 denotes a control unit, which controls the main extension key telephone 105 according to the operation program.

Next, the operation of the button telephone device of this embodiment will be explained.

First, in the flowchart on the main device side shown in FIG. 2, after the main device 100 is powered on, bell signal information is transferred in step 201. That is, the communication unit 102,
A plurality of pieces of bell signal information (A, B, . . . , N, M) stored in the fixed data storage unit 104 are transferred to the variable data storage unit 109 via the extension communication line 112 and the communication unit 107.
is transferred.

When the transfer is completed, in steps 202 and 203, the process waits for reception of a data reception completion response from the extension key telephone 105.

That is, step 202 is for receiving processing, and step 203 is for determining whether or not a desired response signal has been received.
Repeat steps 02 and 203.

When a response is received, the process moves to step 204, in which all previously transmitted bell signal information (A.

B, . ,B,...,N.

M) is transmitted.

If the extension button telephone 105 has successfully received the bell signal information (A, B, . . . , N, M) in step 204, the process moves to the next step 205, and a request for ringing the bell signal is made. If there is no request, the process jumps to step 211 and performs control communication processing other than the bell signal transmission request processing.

Here, a case will be described in which a ringing request for ringing the bell is generated on the extension key telephone 105 due to an incoming call or the like. If it is confirmed in step 206 that a ringing request has been made, the process moves to the next step 206. Step 206
First, confirm the type of bell ringing requested. Then, each bell signal information (a.

b, . . . , n, m) is executed. For example, if a bell (a) is requested, step 207 is executed, and a request signal corresponding to bell (a) is transmitted from the communication unit 102. Further, if Bell (n) is requested, step 208 is executed, and a request corresponding to Bell (n) is transmitted from the communication unit 102.

Thereafter, the process moves to step 209, in which a response is received indicating that the transmitted bell sending request has been received by the extension key telephone 105, and in the next step 210, it is determined whether or not the response reception has been completed. Unless reception of a response signal is confirmed in step 210, the process returns to step 209 and continues in the response reception standby state in steps 209 and 210.

By the way, when the reception of the response is confirmed in step 210, the process moves to the next step 211, and control communication processing other than the bell signal transmission request processing is performed, and when all processing is completed, the process returns to the previous step 205, and the request for ringing the bell signal is processed. Repeat the presence/absence determination again. The subsequent operations after step 205 are similar to those already described.

Next, the flowchart of the extension button telephone set shown in FIG. 3 will be explained. At step 301, when the power is turned on,
As described above, the communication unit 107 receives the bell signal activation information (A, B, . . . I N IM) transmitted by the main device 100, and stores a plurality of pieces of bell signal activation information (a) in the variable data storage unit 109.

b, ... n, m). Then, in the next step 302, all the information received (a.

b, .
An abnormal reception response is sent.

If the security information is normal, a normal reception response is transmitted in step 304. 305 is a step of receiving the request signal, and 306 is a step of determining whether or not reception of the request signal is completed. In this step 305 and the next step 306, the main device 100 waits to receive various requests sent from the main device 100. That is, in step 306, it is determined whether or not the request reception has been completed, and if it has not been completed yet, the process returns to step 305 and repeats the request reception standby.

By the way, when a request is received, the received request goes to step 3.
In step 07, it is determined whether or not the request is related to ringing of a bell signal. If the request is not related to ringing of a bell signal, the process jumps to step 312, but if the request is related to ringing of a bell signal, the request is made to ring the bell signal in the next step 308. Move to type determination. In the bell signal ringing type determination in step 308, based on the received request, the corresponding bell signal information is selected from among the bell signal information (a, b*..., n, m) in the variable data storage unit 109, Appropriate processing is executed from among the processes from Bell (a) transmission activation processing (step 309) to Bell (n) transmission activation processing (step 310). Then, the process moves to step 311. In step 311, a response is sent to the main device 700 to the effect that the bell signal activation has been completed. Next, the process moves to step 312, where other received requests are checked and various operations are started/stopped, and the process returns to step 305, where the operations from step 305 described above are performed.

As described above, this embodiment eliminates the need to equip the extension button telephone with a fixed data storage section that stores a plurality of pieces of bell signal activation information, and instead stores the main unit's information in a variable data storage section that can be rewritten at any time. When the power is turned on, prior to normal operation, a plurality of bell signal activation information in the fixed data storage section of the main device is transferred to the variable data storage section in the extension key telephone.

Furthermore, although the above explanation describes the operation in response to a request to start ringing a bell signal to the extension button telephone 105, it is obvious that it is possible to similarly explain the operation in response to a request to stop the ringing of the bell signal. It is.

However, in the above embodiments, it is necessary to estimate the capacity of the variable data storage section that is pre-equipped in the extension key telephone, which may result in high costs. Accordingly, in the following second embodiment, the variable data storage section of each extension key telephone can store at least one piece of bell signal ringing information.

Next, a second embodiment will be described. FIG. 4 is a block diagram showing the configuration of the key telephone device in the second embodiment.

400 is a main device, and 405 is an extension key telephone.

In the main device 400, 402 is an extension key telephone 40
The communication unit 404 sends and receives control requests and control responses to and from the communication unit 407 of 5, and the communication unit 404 sends and receives a plurality of bell signal ringing information (A, B, ・
. . , N, M>, a fixed data storage section 40
3 is a program storage unit, and 401 is a control unit.

In the one-way line button telephone 405, 407 is a communication section. 409 can freely rewrite the memory contents, and the main device 4
Bell signal ringing information such as multiple bell tones, bell ringing patterns, and bell volume (A, B, . . .
, N, M) and can be stored as bell signal ringing information (0). 410 is a D/A conversion section width section 11 is a speaker;
08 is a program storage unit, and 406 is a control unit.

Next, the operation program of the button telephone device of this embodiment will be explained based on FIGS. 5 and 6.

First, in the flowchart of the main device 400 in FIG.
The main device 400 determines whether or not a bell signal request has occurred in step 501, and if it has not occurred, step 511
If a request has occurred, proceed to the next step 5.
02, a bell signal activation request is sent to the extension key telephone 405 via the extension communication line 412, and after sending the request, the process waits for a response to the previous bell signal activation request in steps 503 and 504. , if no response is received, steps 503 and 504 are repeated to continue receiving the response.

By the way, in step 504, the extension key phone Wk405
Upon receiving a response from , the process moves to the next step 505,
Selects the transfer of request bell signal activation information. Step 5
The transmission bell signal activation information selected in step 05 is
It is any one of the bell (a) pattern data of step 06 to the bell (n) pattern data of step 507. Thereafter, in steps 508 and 509, the extension key telephone 405 waits for a response indicating that the bell signal activation information has been successfully received.If the response is not received yet, steps 508 and 509 are repeated, and the response is received. Continue waiting. By the way, when a response is received, step 510
The content of the response is determined, and if the response is that the response could not be received normally, the process returns to step 505.
Attempt to send the bell signal activation information again. By the way, if the response is that it was received normally, then proceed to the next step 51.
1, and if there is another request, a communication processing operation is performed in accordance with the request, and the process returns to step 501 to wait for a request.

Next, a flowchart of the extension key telephone 405 shown in FIG. 6 will be explained. Step 601 and Step 602
monitors the reception of some kind of request from the main device 400,
If no request is received, step 601 and step 60
2 is repeated, and when it is determined in step 602 that a request has been received, the process moves to the next step 603, in which it is determined whether the request is related to ringing the bell signal, and the bell signal is activated. If the request is not related to the above, the process jumps to step 610, and if the request is related to the activation of the bell signal, the process proceeds to the next step 604, and a response is sent to the extension key telephone indicating that the previous request has been received. do. Thereafter, in step 605, at least one piece of bell signal information transmitted from the main device 400 is subsequently received and stored in the variable data storage section 409 as bell signal activation information (0). Next, in step 606, the normality of the previously received information is checked, and if it is not normal, the process moves to step 607, a response of abnormal reception is sent, and the process returns to step 605, where the bell signal activation information is received again. I do. By the way, if the reception is normal, the process moves to step 308, and after transmitting a response indicating normal reception, the process moves to step 609, where the A/ The D conversion converter width section 410 outputs a bell signal to the speaker 411. After that, the process moves to step 610, and other reception request checks and operation start/stop control for the extension key telephone 405 are performed, and then step 610 is performed again.
It returns to 1 and waits for a request to be received.

The above explanation describes the operation in response to a request to start ringing a bell signal to the extension button telephone 405, but it is obvious that it is possible to similarly explain the operation in response to a request to stop the bell signal. be.

As described above, in this embodiment, each time a need arises, the main device sends the bell signal information to the extension key telephone one by one and stores it in the variable data storage section in the extension key telephone. It is possible to design a variable data storage section of an extension key telephone at low cost by simply equipping it with a variable data storage section that can store one piece of bell signal activation information.

Effects of the Invention As described above, in the present invention, each extension key telephone is equipped with a variable data storage section that can be rewritten at any time and has a capacity capable of storing a plurality of bell signal information, and the breeding device is equipped with a program storage section. Separately, it is equipped with a fixed data storage unit that stores multiple bell signal information, and before using the bell signal, the multiple bell signal information in digital format stored in the fixed data storage unit on the main device side is temporarily stored. It is configured to be transferred and copied to the variable data storage section of the extension button telephone via the extension communication line, and when ringing a bell signal, the information obtained by accessing the variable data storage section of each extension button telephone is used. By creating a bell signal based on the base and sending that signal to the speaker, if new bell signal information is required due to the addition of a new service to the main device, the bell signal information can be stored only in the main device. By replacing the fixed data storage unit, it is possible to operate with the new bell signal information as is, so there is no need to change each extension button telephone, and the effort required to change the bell signal information can be greatly reduced. I can do it. Also, with this configuration, it becomes possible to provide the user with a program storage section that stores various services and a fixed data storage section that stores new health signal ringing information in the form of a memory bag. By simply replacing the main unit's memory pack, it is now possible to use the multiple extension button telephones currently in use with the main unit that provides the new service.
It is extremely versatile (and can be made highly expandable).
