An incoming sound source 49 for notifying the extension telephone 52 that there is an incoming call, an extension telephone interface circuit 50 for connecting the extension telephone 52 to a main unit, and an incoming call of the extension telephone 52 when there is an incoming office call. A ring tone designation table 51 for designating a sound destination is provided.

[0005] The ring tone ringing designation table 51 stores data for designating which extension telephone 52 to ring when an incoming line is received, and the content of the data depends on the setting. It is variable.

Next, a conventional ringing tone ringing method will be described. When there is an incoming call from the public network 53 via the office line, the office line interface circuit 48 notifies the CPU 47 that there is an incoming call from the office line by an internal incoming call detection unit. The CPU 47 that has been notified of the incoming central office calls the plurality of extension telephones 5 in order to make the extension telephone 52 ring a ring tone.
2, the ring tone ringing designation table 51 is referred to the ring tone ringing designation table 51, and the extension interface circuit 50 connected to the ring tone source 49 and the designated extension telephone 52 according to the table contents. The time-division switch 46 is controlled to connect the communication path. As a result of the call path connection, a ring tone sounds to notify that there is an incoming office line at the extension telephone designated in advance by the ring tone ringing designation table 51.

As described above, in the ring tone ringing circuit constituting the above-described conventional private branch exchange, it is possible to ring a ring tone to an arbitrary extension telephone set in advance at the time of receiving an office line.

9 is set to "on".

Based on the above result, the number of incoming calls and the circuit N
O. A ring tone sounds to notify that there has been an incoming office line on the extension telephone set that matches the comparison result.

In the first embodiment of the present invention, the number of incoming calls, the circuit NO. In FIG. 3 showing an example of the relationship between the ring tone control and the ring tone ringing control, circuit NO. , The number of incoming calls is given by three bits in binary. The comparison block is defined by the comparison block designating unit 17, and in this example, the comparison can be performed on the lower 1 bit to 3 bits (all bits). Also,
It is also possible to specify no comparison (0-bit comparison), and in this case, the changeover switch 19 is always in the " on " state. It is assumed that

In the present embodiment, when the extension telephone 24 goes off-hook for answering or calling, the extension interface unit 16 detects off-hook and sets the comparison content designation of the comparison block designation unit 17 to "0" (comparison). No), and the changeover switch 19 is always set to “on”. This allows
The other operations are not affected.

As described above, according to the above-described embodiment, each time a certain number of incoming calls is reached, the number of incoming calls and the circuit NO. And the on / off control of the ringtone is possible. For this reason, among the telephones designated to ring, it is possible to further change the telephone to which the ring tone sounds according to the number of incoming calls.

(Modification) FIG. 4 shows a configuration example of a ring tone ringing circuit applied to a modification of the first embodiment.
FIG. 4 shows a ring tone ringing circuit used in the first embodiment instead of FIG. 2. The private branch exchange system shown in FIG. 1 and the configuration example of the ring tone tone designation table 7 shown in FIG. It also applies in the examples.

In the modification of FIG. 4, the ringing sound is simply turned on / off by the changeover switch 19 in the above embodiment, but the changeover switch 37 of this modification changes the ringing sound on / off.
The off type has been changed to the bipolar selection type. The changeover switch 37 has two different ringing sound sources, a ringing sound source # 1 (32) and a ringing sound source # 2, via the time division switch 31.
(33) are connected to each other.

By adopting the configuration of this variation, as is clear from the above embodiment, each time the number of incoming calls differs from the number of incoming calls, the number of incoming calls and the circuit NO. And it is possible to switch the incoming sound source. For this reason, the type of ringing sound can be changed according to the number of incoming calls among telephones designated to ring. Therefore, the circuit NO. By setting the ringing sound classified by the number of incoming calls for each call, it is possible to discriminate the destination by the number of incoming calls based on the ringing sound.

(Second Embodiment) FIG. 5 shows a configuration example of a ring tone ringing circuit applied to the second embodiment.
The second embodiment shown in FIG. 5 differs from the first embodiment in the location of the ringing tone ringing circuit. In the first embodiment, the ring tone ringing circuit is installed in the private branch exchange, but in the second embodiment, it is installed in the telephone device.

In the variation of FIG. 5, the ring tone ringing circuit 6
0 is the extension telephone interface circuit 11, the office line / extension interface circuit 12, and the circuit NO.

The ringing tone ringing circuit 60 of this configuration is connected to the exchange 70 via the office line / extension interface circuit 12.

The extension telephone interface circuit 11 has a circuit NO. The designating unit 13 sets the circuit number in the ringing tone ringing circuit 10. Is uniquely defined. In the present embodiment, for example, the circuit NO. Is given from the young number “0” in the binary definition.

The extension telephone interface circuit 11 is further subdivided and includes an incoming sound source on / off control unit 26 and a ringing unit 61.

The on / off control unit 26 is further subdivided into a switch 19 for selectively turning on / off the incoming sound source, and a comparator 18 for controlling the switch 19. The comparator 18 receives the incoming call count
0 and the circuit number. Designating part 13
Circuit NO. Are performed for the number of bits specified by the comparison block specifying unit 17, and the selective on / off control of the changeover switch 19 is performed based on the result.

The office line / extension interface circuit 12 is further subdivided into an office line interface section 21 connected to the exchange 70, an incoming call detecting section 22 for detecting an incoming call, and an incoming call number converting section 23 for detecting the number of incoming calls. It is configured to have.
The detection result of the number of incoming calls in the central office / extension interface circuit 12 of this configuration is based on the extension telephone interface circuit 1
1 is notified to the number-of-incoming-number receiving section 20.

The ring tone ringing circuit 60 of this configuration has two types of sound sources, the ring tone source 15 and the ringing unit 61. These sound sources differ in the basic configuration of the sound source. For example, the incoming sound source 15 is a mechanical sound source such as a bell buzzer, and the ringing unit 61 is a sound source such as a voice synthesis circuit and a sound memory circuit. I do. The two sound sources are selectively changed by the changeover switch 19, and are selectively used depending on the function, operation state, purpose, destination, and the like.

According to the present invention, as is apparent from the above embodiment, the ringing tone of the extension telephone and the sound source of the extension telephone can be switched according to the number of incoming calls. Therefore, for every preset number of incoming calls,
Responders to incoming line calls can be fairly distributed. Further, since the ringing tone of the extension telephone can be switched according to the number of incoming calls, it is possible to clarify the respondent to the incoming call.

The above embodiment is a preferred example of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention. For example, in the embodiment, two types of incoming sound sources are used, but it is also possible to select from three or more types of sound sources based on various types of sound, such as sound source, gradation, tempo, intensity, interval, rhythm, and the like. is there. Further, there is a method using not only the ring tone but also other recognition means such as flash light.
