Abstract

PURPOSE:To vary a calling sound from a caller side by providing a means setting the sound volume of a calling sound of a telephone set of a called party by a caller. CONSTITUTION:When a caller hooks off, a subscriber circuit 3 is connected to an outgoing register trunk 7 via a switch 6 and enters a dial information supervisory state. In dialing tone volume information in addition to an extension number, a called party number and sound volume information are detected from the trunk 7. In detecting the sound volume information, the detected sound volume information is set as it is. In controlling relays 15-18 in subscriber circuits 3, 4 corresponding to the sound volume information next, the calling sound is sent from a telephone set of the called party.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a ring tone volume control device in an electronic automatic switchboard.

[Prior Art] Conventionally, the ringer volume of an extension telephone in an electronic automatic switching system has been set using a volume for adjusting the output volume built into the telephone.

[Problems to be Solved by the Invention] In the conventional volume setting method mentioned above, the ring tone setting is unique to each telephone and cannot be changed unless the called party's telephone is adjusted. The disadvantage is that it cannot be done.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device for setting the ringing volume of a called party's telephone from the calling party side.

[Means for Solving the Problems 1] The ring tone control device of the present invention includes a means for a calling party to set volume information of a ring tone to be sent to a called party, and a means for setting volume information of a ring tone to be transmitted from a telephone of the called party to an external device based on the volume information. The device is characterized in that it has means for controlling the volume of the ringing tone sent to the user.

[Embodiments] Two embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall block diagram of an embodiment of the present invention. 1st
In the figure, 1 is the calling party's telephone, 2 is the called party's telephone, and 3 is the calling party's telephone.
, 4 are subscriber circuits, and 5 is a ringing tone signal generation source. 6 is the switch matrix, 7 is the outgoing register trunk, 8
9 is an input/output interface, 9 is a memory, and 10 is a central control unit.

FIG. 2 shows an embodiment of the ring tone volume control circuit inside the hu person circuit 34. In FIG. In FIG. 2, 11 to 14 are ringing signal current limiting resistors, 15 to 18 are relay contacts,
19 to 22 are relay coils, 23 to 26 are relay driving gates, and 27 is a latch circuit.

FIG. 3 is a flowchart of an embodiment of the present invention.

In the present invention having the above configuration, the calling party sets the volume information of the ring tone to be sent to the called party by dialing the sub-volume information of the called party number after the calling party's off-footer. This is realized by detecting the volume information in addition to the called party number. The means for controlling the volume of the ring tone transmitted from the telephone of the called party to the outside based on the volume information is a relay contact of the ring tone volume control circuit inside the subscriber circuits 3 and 4 in accordance with the set volume information. 15 to 18 as latch circuit 2
This is achieved by controlling through the 7° gates 23-26.

Next, the operation will be explained with reference to the flowcharts of FIGS. 1, 2, and 3. When the caller goes off-hook, subscriber circuit 3
is connected to the calling register trunk 7 via the switch 6 and enters the dial information monitoring state (31). When the caller dials the called party's extension number and volume information (numbers from 1 to Q), the called party's number and volume information are detected by the i-register trunk 7 (S2). If the volume information is not dialed and the volume information is not detected (S3), the volume information is prepared in advance and the file default data (for example, the standard value "
5" etc.), the volume information is dialed,
If volume information is detected, the detected volume information is set as is (S4). Next, by controlling relays 15 to 18 in the subscriber circuit in accordance with the gfJ information as shown in the example in the table below (S5), a ringing tone is transmitted from the telephone of the called party.

In this example, the resistance values of the ringing signal current resistors 11 to 14 are set to have the following relationship: resistance value of resistor 11 > resistance value of resistor 12 > resistance value of resistor 13 > resistance value of resistor 14. 1 corresponding to the size of the information number
You can set 0 levels of money transfer.

[Effect of the invention 1 As explained above, the present invention allows the caller to set the ringer volume of the called party's telephone, taking into consideration the environment in which the called party is placed, and to make a call. The ring tone can be changed from the party's side, especially when a secretary transfers a call to an executive, depending on whether the executive is in a meeting, whether the executive is far away from the phone, whether the secretary is quiet, etc. This has the effect that it can be used as a system that can remotely control the ringtone.
