BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of the present invention will be described by way of an example of a hold tone changing process in a key telephone. FIG. 1 is a block diagram showing the configuration of a key telephone device which is an embodiment of the present invention. The key telephone main unit 1 accommodates telephone lines or ISDN lines 2, 3 and extensions 6, 7 connected to digital key telephones 4, 5.
The office line interface circuits 10 and 11 are CODECs,
It has a built-in NCU etc. and interfaces with the telephone lines 2, 3 etc. In this embodiment, all signals in the main unit 1 and the key telephones 4 and 5 are digital signals.

The register circuit 12 is a circuit for exchanging signals between the CPU 18 and communication line devices such as the office line interface circuits 10 and 11, and the communication digital signal is also transferred to the switch circuit 13 via this circuit. It The switch circuit 13 has a built-in crosspoint matrix switch, and based on an instruction from the CPU 18, the station line interface circuits 10 and 11, the extension line interface circuit 14,
15, or arbitrary circuits such as the CODEC 17 are connected. The extension interface circuits 14 and 15 include, for example, a ping-pong transmission control circuit for exchanging voice signals and control signals with the key telephones 4 and 5.
Interfaces with key telephones 4 and 5.

When the CPU 18 designates the holding tone number via the register circuit 12, the holding tone generating circuit 16 outputs one of the holding tone melody patterns of, for example, about eight songs.
It is an IC capable of generating one and the output is an analog signal. Such an IC is commercially available.
The CODEC 17 converts the output signal from the hold sound generation circuit 16 into a digital signal and outputs the digital signal to the switch circuit 13.
The CODEC 17 is not necessary if the hold tone generation circuit 16 directly generates a digital signal of the hold tone.

The CPU 18 is a central processing unit that controls the entire key telephone main unit 1 based on a control program stored in the ROM 19. The RAM 20 is used as a work area and a buffer, and may be backed up by a battery or the like. The bus 21 connects each circuit in the main device.

FIG. 2 is an explanatory diagram showing the exchange of signals between the circuits of the key telephone apparatus during the hold tone change processing. When off-hook from any or a particular button telephone, the CPU 18 causes the extension interface circuit 14,
Off-hook is detected via 15 and the key telephone that has gone off-hook, for example, 4 is instructed to send a dial tone for extension connection. Here, the operator performs a specific key operation that means a hold tone change request, for example, pressing the "function" key and then pressing "0" twice. This key operation information is the extension interface circuit 1
4 is transferred to the CPU 18, and the CPU 18 recognizes that the key operation is a hold sound change request.

The CPU 18 gives an instruction to the switch circuit 13 to connect the output of the CODEC 17, which converts the output of the hold tone generation circuit 16 to a digital signal, and the extension interface circuit 14 to which the key telephone 4 is connected. Therefore, the current hold tone (A) is sent to the key telephone 4 as at the time of hold, and the operator holds the hold tone (A).
You can learn the current music on hold music pattern by listening to.

Here, when the operator wants to change the holding tone, he or she performs a key operation for changing the holding tone. As the operation method, for example, a method of directly specifying a holding tone number using a ten-key pad, a method of sequentially changing the holding tone number each time an arbitrary key is operated, or the like can be adopted. When the on-hold tone number is directly specified using the ten-key pad, for example, if the on-hold tone number is 5, then "5" is pressed and then "#" is pressed. The CPU 18 detects the key operation,
When the holding tone number is changed, a new holding tone number is set in the holding tone generating circuit 16 via the register circuit 12.

The hold tone generation circuit 16 immediately generates a new hold tone (B), and the hold tone is sent to the key telephone. If the operator wants to make a further change, he or she repeatedly selects the holding tone, but if the holding tone is acceptable, the operator goes on hook as it is. When the CPU 18 detects the on-hook, it releases the connection and stores the current music on hold number in the RAM 20 for backup.

FIG. 3 is a flowchart showing the hold sound changing process of the CPU 18. In step S1, waiting for an off-hook of any or a specific key telephone, for example, 4 and when the off-hook is detected, in step S2, the key telephone 4 is instructed to send a dial tone for extension. In step S3, the key operation information is sent to C via the extension interface circuit 14.
It is taken into the PU and it is determined whether or not the content is a hold tone change request. Then, if the result is negative, the process shifts to other processing corresponding to the input key operation, but if the result is affirmative, that is, if the key operation information is a specific key operation indicating a hold sound change request. Then, the process proceeds to step S4.

In step S4, the CPU 18 gives an instruction to the switch circuit 13 to convert the output of the hold sound generating circuit 16 into a digital signal and the output of the CODEC 17,
It connects to the extension interface circuit 14 to which the key telephone 4 is connected. In step S5,
The key operation of the key telephone 4 is monitored, and it is determined whether or not the key operation for changing the hold tone is performed. Then, if the result is affirmative, the process proceeds to step S6, and the CP
U18 sets a new holding tone number in the holding tone generating circuit 16 via the register circuit 12, and returns to step S5. In step S7, it is determined whether or not the key telephone set 4 is on-hook. If the result is affirmative, step S7 is performed.
8, the connection between the CODEC 17 and the extension interface circuit 14 is released, and the current holding tone number is stored in the RAM 20 for backup. Through the above processing, the user can change the held sound pattern by a simple operation while monitoring the held sound.

Although the embodiment has been described above, the following modifications are also possible. If you enter the music on hold change process,
A hold tone may be sent to the key telephone, and the display device of the panel of the key telephone may display that the hold tone changing process is currently in progress, and may further display the current hold tone number or song name. .

The holding tone is 1 at the same time for the entire key telephone device.
Although an example in which only types can be generated has been disclosed, it is possible to generate a large number of holding tones at the same time by, for example, a time division operation. It is also possible to transmit the hold tone so that the hold tone number used for each key telephone can be individually set and changed.

Although the example of changing the holding tone is disclosed in the embodiment, in addition to the holding tone, the present invention, for example, makes a ringing tone at the called side, a ringback tone at the calling side, an (extension) dial tone, It can be applied to any audible signal such as a busy sound and an alarm (alarm) sound.

In the embodiment, the example in which the dedicated holding tone generating circuit is used is disclosed. However, the holding tone PCM data stored in the ROM is read out, or the pitch data of the holding tone stored in the ROM CPU based on data)
May generate the hold sound waveform data by calculation, and the CPU may directly output to the switch circuit to generate the hold sound. In the embodiment, the example applied to the key telephone device is disclosed, but the present invention is, for example, a normal telephone,
The present invention can be applied to any communication device that transmits an audible sound signal, such as a facsimile, a mobile phone, a private branch exchange, and a central office exchange.
