Abstract

PURPOSE:To provide the tone control system in which the replacement of a tone ROM or the like is not required for each shipped country. CONSTITUTION:A software control section 23 transfers software tone management data of a designated county to a RAM 26 at the restart processing. When part of the software tone management data is rewritten, the operator inputs a desired tone pattern number from a maintenance console or the like. When the setting of the software tone management data is finished, the software control section 23 informs the software tone management data to a hardware control section 21. The hardware control section 21 reads the tone data designated by a tone pattern number and a tone ID of the software tone management data from a common tone ROM 22 to generate a virtual tone pattern. Furthermore, a call processing tone is generated based on a virtual tone pattern and outputted to a hardware interface 24. Thus, a prescribed call processing tone is outputted to a caller.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tone control system for an exchange which produces a call processing sound according to specifications of each country.

[0002]

2. Description of the Related Art A dial tone sent to a subscriber's telephone and an office line (a dial ready tone output to the caller when the handset of the telephone is lifted), a ringback tone (output to the caller when calling the other party) Call processing sounds (tones), such as the sound that is played) and busy tone (the sound that is output to the caller when the other party is talking), differ in each country.

Therefore, conventionally, as shown in FIG. 7, a tone ROM 10a for country A and a tone ROM 10b for country B are provided.
..Preparing tone ROM for each country such as tone ROM 10z for country Z, and when manufacturing an exchange, insert the tone ROM corresponding to each destination into the socket of the tone control unit 11 The control unit 12 reads the tone data from the tone ROM and sends various call processing sounds to the caller.

The tone ROM for each country stores frequency data such as dial tone, ringback tone, and busy tone used in each country and their interval data.

[0005]

However, the method of manually replacing the tone ROM according to the destination is as follows.
Since the tone ROM may be erroneously inserted or a contact failure may occur, a test process for finding a defect during assembly is required, which causes a problem of manufacturing cost and test cost.

In the above method, the tone ROM is divided by country.
However, there is also a problem that the number of development man-hours is increased. Further, when the destinations increase, the types of tone ROMs also increase and the management becomes complicated, which is a problem.

In addition, when developing a switchboard for a new destination, if the tone of the destination is slightly different from the tone of the existing tone ROM, a new tone ROM must be created and the tone changed. There was also a problem that it could not be easily dealt with.

An object of the present invention is to provide a tone ROM for each destination.
Is to provide a tone control scheme that does not need to be replaced.

[0009]

FIG. 1 is a block diagram showing the principle of the present invention. In the figure, the tone data storage means 1 stores a plurality of tone data constituting call processing sounds that differ for each one or a plurality of countries. The tone data storage means 1 classifies call processing sounds, which are different for each country, into a tone data group consisting of a combination of a plurality of tone data, and the tone data of each group is designated by a tone pattern and each tone pattern. The tone type is stored in association with the tone ID designating the tone type.

The selection means 2 selects any combination of tone data stored in the tone data storage means 1. The tone sending means 3 sends a predetermined call processing sound to the caller based on the tone data selected by the selecting means 2.

[0011]

In the present invention, the tone data storing means 1 in which the tone data constituting the call processing sound that differs for each country is made common.
A call processing sound corresponding to the specifications of each country can be generated by selecting a combination of the tone data stored in (for example, ROM) and stored in the tone data storage means 1. In this case, at least one type of tone data common to multiple countries needs to be stored.
The storage capacity of the tone data storage means 1 can be reduced.

Further, this eliminates the need for exchanging the tone ROM depending on the destination of the exchange as in the prior art, so that the number of assembling steps, the number of test steps and the number of developing steps of the tone ROM can be reduced, and the management of the tone ROM can be simplified.

Further, since a new tone can be generated by combining arbitrary tone data, it is possible to flexibly meet the specifications of a new country different from the existing tone pattern.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 is a diagram showing a configuration of an exchange to which the tone control method of the embodiment is applied.

In the software control section 23, country type data is R
It is stored in the OM or the like, and a specific country type, a tone pattern corresponding to the country type, and a tone ID are designated and notified to the hardware control unit. The hardware control unit 21 reads tone data corresponding to the tone pattern and tone ID notified from the software control unit 23 from the common tone ROM 22 and outputs it as call processing sound to the caller as necessary.

The common tone ROM 22 stores a plurality of tone data (dial tone,
The tone data of a plurality of tone patterns is stored with a combination of data (ring back tone, busy tone, etc.) as one tone pattern.
The pattern stores dial tones, ring back tones, busy tones, etc. of the United States and Mexico.
The dial tone, ringback tone, busy tone, etc. of Australia and New Zealand are stored in the pattern. Similarly, different tone data are stored in correspondence with tone patterns.

Next, the tone control system of the embodiment will be described with reference to FIG. In FIG. 3, the soft tone management data is data including a tone pattern and a tone ID corresponding to a destination created by the software control unit 23. The soft tone management data is designated by a target country. When read, it is read from the ROM 25 of FIG. 4 described later.

The soft tone management data is notified to the hardware control unit 21, and the tone pattern corresponding to the tone pattern and tone ID designated by the soft tone management data is read from the common tone ROM 22 in the hardware control unit 21. Then, a virtual tone pattern is created. Then, a call processing sound is generated based on the virtual tone pattern, and the call processing sound is generated by the hardware interface 2
4 to the caller.

The tone control operation will be described below with reference to the operation explanatory diagram of the software control section 23 and the hardware control section 21 of FIG. 4 and the flowchart of FIG. 5 showing the processing operation of each control section.

At the time of restarting the exchange (processing for initializing the hardware and software), the tone pattern number and tone I of the target country stored in the ROM 25 are stored.
D is transferred to the RAM 26 as soft tone management data (FIG. 5, S1).

This ROM 25 has country-specific data (see FIG. 2).
Tone pattern number and tone I of each country
D and D are stored as soft tone management data. In FIG. 4, tone pattern number A is tone ID 1,
The data of tone ID 2 ...
Transferred from M25 to RAM26.

Next, a person determines whether or not all the soft tone management data matches the tone pattern of the applicable country (target country) (S2). When shipping a switchboard to a new country and the call processing sound of that country is partly different from the call processing sound of the existing country, the tone patterns do not match, so the soft tone management data in RAM 26 is displayed. The tone pattern number is changed by operating the maintenance console (not shown) in the state of being displayed on the screen (S3).

FIG. 4 shows a state in which the tone pattern number of the ring back tone in the soft tone management data of the RAM 26 is rewritten from A to B. Next, the soft control unit 23 notifies the hard control unit 21 of the soft tone management data transferred from the ROM 25 or the soft tone management data in which a part of the soft tone management data is rewritten (FIG. 5, S4).

The hardware control section 21 needs to read the tone data designated by the tone pattern number and the tone ID of the soft tone management data from the common tone ROM 22 to create a virtual tone pattern, and thereafter send the tone to the caller. Each time, a dial tone, a ring back tone, or a busy tone is created based on the virtual tone pattern and is output to the hardware interface 24 (S5).

In the common tone ROM 22, for example, tone data of each tone pattern is stored in the order of dial tone, ring back tone, busy tone and the like. Further, the tone pattern numbers A, B, ... Indicate the type of tone pattern, and at the same time, the start address of the tone data of the A pattern stored in the common tone ROM 22,
Shows the start address of pattern B ...
1, ID2, ... Show the tone type and at the same time show the displacement of the address in each tone pattern.

That is, in any of the tone patterns A to Z, the tone ID1 is the dial tone storage address, the ID2 is the ringback tone storage address, and I
D3 indicates a storage address of the busy tone.

Therefore, when changing the soft tone management data, it is sufficient to change only the tone pattern number while keeping the tone ID. For example, when the tone pattern number A and tone ID 1 and the tone pattern number B and tone ID 2 are designated in the soft tone management data, the hardware control unit 21 is designated by the tone pattern number A in the common tone data ROM 22. The tone data (dial tone data) stored at the address position where the address displacement from the address is ID1 (position # 1 of the A pattern in FIG. 4) is output as virtual tone pattern data and designated by tone pattern number B. The tone data (ringback tone) stored at the address position (position # 2 of the B pattern in FIG. 4) whose address displacement from the stored address is ID2 is output as virtual tone pattern data.

Next, FIG. 6 shows a ROM in the software control section 23.
FIG. 3 is a diagram showing an example of soft tone management data and virtual tone patterns created from soft tone management source data stored in FIG.

For example, as the destination, the United States (country ID
When "1") is specified, the soft tone management source data of ID1 is transferred from the ROM 25 (see FIG. 4) to the RAM 26. In this state, by operating from the maintenance console, RA
Tone ID of tone type e of M26 soft tone management data
Is changed from ID3 to ID6, the tone pattern number and tone I specified by the soft tone management data are changed.
D tone data is read from the common tone ROM 22 to create virtual tone pattern data. Then, a required call processing sound is generated based on the virtual tone pattern data.

As described above, in the above embodiment, the tone data is stored in the common tone ROM 22 in association with the tone pattern number and the tone ID, and the tone pattern number of the common tone ROM is stored according to the specifications of the destination. Since the virtual tone pattern is created by designating the tone tone ID and the tone ID, and the call processing sound is generated based on the virtual tone pattern, the tone data stored in the common tone ROM 22 is combined to generate a virtual tone pattern. Call processing sounds can be created.

In this case, it is sufficient to store at least one same tone data in the common tone ROM 22, and it is not necessary to store all the tone data of each country, so the storage capacity of the ROM can be small.

Further, when manufacturing an exchange that meets the specifications of a new country, for example, a tone pattern number and a tone ID corresponding to the call processing sound of that country can be set in the RAM as soft tone management data. Often, it is not necessary to change the common tone ROM 22, so change the specifications,
Can flexibly respond to additions.

In the above embodiment, the dial tone,
A common tone ROM with a tone data group consisting of ring back tone, busy tone, etc. as one tone pattern
However, for example, dial tones, ring back tones, busy tones, etc. of each country in the world are stored as one group in the common tone ROM 22, and a specific dial tone in each group is stored depending on the destination.
A ring back tone or a busy tone may be selected.

[0034]

According to the present invention, since the storage means for storing the call processing sounds of a plurality of countries, for example, the tone ROM is shared by one, the development man-hours of the tone ROM can be reduced. Moreover, management of the tone ROM is also simplified. Furthermore, since there is no need to manually insert the tone ROM suitable for the destination into the socket as in the conventional case, a test process for inspecting erroneous insertion of ROM, contact failure, etc. becomes unnecessary. Further, since tone data of different tone patterns can be combined to create another tone pattern, it is possible to easily meet the specifications of call processing sounds of a new country without changing the tone ROM.
