Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device, and more particularly to a telephone device in which ringtones of different tones are produced between terminal phones.

(Prior Art) Among telephone devices including a private branch exchange, a key telephone device, etc., for example, a button telephone device is generally a button telephone main device (hereinafter abbreviated as main device) accommodating a telephone line, and the main device. It consists of a number of key telephones connected to.

When an incoming call is received on the telephone line, the main unit detects and decodes the incoming call information, and usually determines which one of a large number of key telephones should ring the ring tone. The key telephone selected by this determination rings with a predetermined ring tone and notifies a person that an incoming call has arrived.

(Problems to be Solved by the Invention) In recent years, telephone devices such as button telephone devices have come to be used in large capacity. In many cases, one office of this type has a large-capacity device of this type, specifies a line to be used for each department and section, and shares one device for each group to improve efficiency.

For example, assuming that the device accommodates 10 office lines, 5 of them are dedicated to the A section, the remaining 3 are used in the B section, and the remaining 2 are used in the C section. Similarly, button telephones will be arranged in units of 30, 20, and 10 units, and will be used for each department.

On the other hand, in this type of key telephone device, the ring tone of the key telephone is the same for all the telephones.

Therefore, as in the office, etc.
If the departments A, B, and C all live together,
A large number of button telephones are concentrated in a certain narrow place, and when there is an incoming call, it is difficult to determine which department's telephone is ringing. Therefore, there is a problem that it sounds as if an incoming call is received even though it is not actually received, and there is a trouble that the handset of the key telephone is wrongly picked up.

In addition, when a person (handler) who answers an incoming call is set in advance for each group, only the key telephone at that operator may be made to ring as the group representative, but even in such a case, there is no operator. In this case, someone in that group should answer, but if you leave it without knowing the absence of the operator, someone in another group close to that operator will erroneously recognize that it is an incoming call to your group and will respond. There was a problem that it would end up.

These problems are the same not only in the key telephone, but also in the private branch exchange or the like.

The above-mentioned conventional technique has the above problems.

An object of the present invention is to solve the above problems by making the ringing tone different for each terminal telephone or each group and for each line type or rotation.

(Means and Actions for Solving Problems) In order to solve the problems described above, the present invention determines the type or the line of the line 1 which has received an incoming call as shown in the block diagram of FIG. Identifying means 2 for identifying, storage means 3 for storing ringing tone data corresponding to line type or line by terminal phone alone or group, line type or line and terminal phone identified by the identifying means 2. The control means 4 reads out the ringing tone data from the storage means by using as an address, and the ringing tone generator means 5 outputs the tone color selected by the ringing tone data.
The point is that different ringtones are generated for each terminal telephone or each group and for each line type or line corresponding to the incoming call.

(Example) With reference to the drawings, a detailed description will be given below based on an example in which the present invention is applied to a key telephone device of a telephone device.

FIG. 2 is a block diagram showing the overall configuration of the key telephone device of the present invention. ME is a telephone main unit that accommodates a telephone line and controls button telephone buttons by a stored program method, KT
-1, ..., KT-m are key telephones, CO-1, ... CO-n are office lines (including the extension of the private branch exchange BX), LN-11, LN
-21, LN-1m, LN-2m are cables for connecting the key telephone main unit ME and the key telephone KT-1, ... KT-m.

In this figure, the power supply units for control and operation are omitted for simplification, and the internal structure of the button telephone KT-m is the same as that of the button telephone KT-1. There is.

The KEY included in the button telephone is a keyboard including rotation selection keys, numeric keys, setting keys, etc., LED is a light emitting diode as an indicator light for indicating the usage status of office lines and extensions, and HS is a hook switch. . Further, 5 is an incoming sound source that generates different tones according to the present invention,
Line tone (ring tone from general line mode), PBX extension ring tone (ring tone via private branch exchange PBX), extension ring tone (ring tone from outside key telephone KT-j) and dedicated A line ring tone (a ring tone from a terminal connected to a dedicated line) is generated, and one of the ring tones is selected by the control information of the control circuit CPU and output to the speaker SP. SP is a speaker that emits the ringing tone of the tone color selected by the ringing tone source 5.

Also, the control circuit (processor) CP of the button telephone type device ME
U is operated by a program previously stored in the read-only memory ROM, and the control circuit (processor) KPU of the key telephone KT-1 ... KT-m is operated by a program previously stored in the read-only memory KOM. There is.

The tone generator circuit TONE has a function of generating a dial tone and a holding tone of different tones.

The control circuit CPU constantly monitors which station line CO-i has received the incoming call by sequentially referring to the incoming call detection circuits INC-1, ... INC-n. The clock circuit CLK measures the call time of each key telephone KT-j, the ringing time (the time from the start of ringing of a ring tone to the response), and the like.

Also, in the general incoming call mode, if there is a call from the station line,
Which of the key telephones KT-1 to KT-m is to be used for ringing the local line is designated in advance in the RAM. Here, it is assumed that the key telephone KT-m is that.

If an incoming call arrives on any of the station lines CO-1, ... CO-n (CO-i) while operating in the general incoming call mode, the corresponding station line circuit COT
The incoming call detection circuit INC-i of -i detects incoming call information, and this is sent to the control circuit CPU.

The control circuit CPU reads out a key telephone (a KT-m in this example) designated for ringing from the random access memory RAM, reads out sound source selection information, and sounds a ring tone corresponding to the information. The control information is transmitted to the key telephone set KT-m via the transmission / reception circuit XR on the main device ME side and the transmission / reception circuit KXR on the key telephone side.

As a result, on the key telephone KT-m side, the corresponding ring tone is selected and output by the ring tone generator 5. In this case, the line tone is selected, and the line tone unique to the button telephone is emitted from the speaker SP. At the same time, the light emitting diode LED corresponding to the incoming call line lights up or blinks.

On the key telephone KT-m side, if you operate the keyboard KEY to select an incoming call-compatible line and raise the handset to respond, the control circuit KPU of the key telephone KT-m detects this and the key telephone side A response signal is transmitted to the control circuit CPU on the key telephone main device ME side via the transmission / reception circuit KXR, the transformer T6, the transformer T-2m, and the transmission / reception circuit XR on the main device ME side.

In response to this, the control circuit CPU stops transmission of the sound source selection information and causes the office line circuit COT-i to form a loop, and then connects the office line CO-i to the office line circuit COT-i and the communication path. It is connected to the call circuit KSL of the key telephone KT-m designated to ring through the network SW and the transformer T-1m.

In this way, a call path between the office line CO-i and the key telephone KT-m is formed.

Next, the function of one embodiment of the present invention will be described in more detail with reference to FIGS. 3 and 5.

FIG. 3 shows a functional flowchart for setting a ring tone for each key telephone and for each line type in the RAM of the main device ME. Further, FIG. 5 shows a functional flowchart in the case of ringing a ring tone for each key telephone and for each line type when an incoming call is received.

First, according to the function flowchart of FIG.
The function of setting the ringtone to be explained.

The control circuit CPU in the main device ME first determines whether or not the operator has lifted the handset to hook up (step S1). This is because when the handset is lifted, the response information (for example, a signal indicating that the hook switch is closed) is transmitted / received by the key telephone.
It is detected by being transmitted from the KXR to the control circuit CPU via the receiving circuit XR of the main device.

When it is determined that the telephone has been hooked up, the control circuit CPU determines whether or not the key telephone KT is in an idle state (step S2), and the extension DT (dial tone) is set to the key telephone.
Connect to KT (step S3). This is a speech path control circuit
Controls the voice network SW through the SWC, and the sound source circuit T
This is done by connecting ONE to the key telephone KT.

Next, the control circuit CPU determines whether or not the tone color setting key (or function key + other predetermined key) of the key telephone KTB is turned on and an operation for setting the tone color switching is performed (step S4). ), If it is determined that the tone color setting key (or function key + other predetermined key) is turned on, the control circuit CPU enters the incoming tone color switching mode.

Here, it is in a state of waiting for the input of the sound type. Then, the control circuit CPU determines whether or not the tone type key is turned on (step S5), and if the operator operates the X key (dial key) and the setting key after this is YES, the parameter Temporarily store X (step
S6). Here, the parameter X is input with the dial keys, and the operation of the setting keys is performed for division.

When the above operation is completed, the line type input waiting state is entered.
Therefore, the control circuit CPU determines whether the line type key is turned on (step S7). If it is determined that the line type key is turned on, the system waits for the Y key (dial key) and the setting key to be input, and when there is input, the parameter Y is temporarily stored (step S8).

The parameters X and Y are determined by the number of information items, but it is preferable that the information items have up to two digits.

When the series of input operations in steps S4 to S8 above are completed,
Ringing type (determined by the parameter X) information is set in the storage area corresponding to the line type (determined by the parameter Y) of the key telephone KT in which the handset is picked up.

Then, it is determined whether or not the setting operation is completed based on whether or not there is a hookdown (step S10), and in the case of No, the process returns to step S5 to accept the setting of ringing information for another line. If there is a hookdown, the process ends.

FIGS. 4 (a), (b) and (c) are conceptual diagrams of data set in the RAM. From this conceptual diagram, it can be understood that the line type and key telephone are used as the RAM address, and the ring type is entered in the data. (A)
Is an example of data in which the ring type is set for each key telephone,
(B) is an example of data in which the ring tone type is set for each group of key telephones.

In the above embodiment, the ring tone is changed according to the line type, but it may be changed according to the line as shown in (c). As is well known, in a key telephone device, there is a telephone main device because it is possible to freely set in advance the telephone main device or the telephone main device from which terminal telephone to ring when an incoming call arrives on a certain line. When an incoming call is received on a line, it is possible to identify which terminal telephone the incoming call is on this line.

Next, the function of generating a sound according to the type of the incoming line when an incoming call is received will be described with reference to FIG.

The control circuit CPU of the main unit ME judges whether or not there is an incoming call (step S20), and if there is an incoming call, it is checked whether or not the called telephone (eg, KT-i) is available (step S20).
S21). When it is determined that the call is vacant, it is determined whether the incoming call is from the central office line, the PBX extension, or another party (steps S22 and S23).

Then, when it judges that there is an incoming call from the central line, the control circuit
The CPU accesses the RAM by using the KT-i and the station line as an address, and reads out the tone color information corresponding to the KT-i station line incoming (step S24).

When the control circuit CPU reads out the tone color information from the RAM, it transfers this to the KT-i (step S26). Upon receiving the tone color information, the KT-i selects the sound source 5 (see FIG. 2) corresponding to the tone color information (step S27), and causes the speaker SP to ring based on this.

Next, it is determined whether or not the operator has responded to this (step S28), and if there is a response, the process ends.

As described above, according to this embodiment, for each key telephone,
Different ring tones can be generated depending on the line type or line. Similarly, different ringing tones can be generated for each group of key telephones.

In the above embodiment, an example is shown in which each ring tone is generated by the ring tone generator 5 provided on the key telephone KT side, and any ring tone is selected and output based on the control information from the main device ME side. However, the present invention is not limited to this, and the same operation can be performed by collectively accommodating in the tone generator circuit TONE in the main device ME, causing it to occur, selecting it, and then transmitting it to the button telephone KT side. In this case, the key telephone KT side simply outputs any one of the selected and transmitted ringing tones through the speaker SP.

(Effects of the Invention) As is clear from the above description, according to the present invention, the following effects are achieved.

(1) Which terminal phone (or group of terminal phones) and what kind of line received the call, even if many terminal phones are gathered together in a small area such as in an office Can be clearly identified.

(2) When the ring tone color is specified for each line, it is possible to determine which line of the terminal telephone set (or of which group terminal telephone set) has received the call only by listening to the ring tone.

(3) It is possible to easily change the ring tone color for each terminal telephone or each group.
