Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subscriber line voice information transmission device, and more particularly to a subscriber line voice information transmission device for realizing a voice information providing service for analog general subscribers in a public network.

[0002]

2. Description of the Related Art An example of a conventional method for transmitting voice information during a call is shown in FIG. 2 and will be described. As a conventional method for transmitting voice information to a calling subscriber who is calling a called subscriber, as shown in FIG. 2, the control device 15 in the subscriber exchange 11 controls the communication path switch 12 to make the subscriber telephone set. There is a method of changing the connection of the ringing tone trunk 16 from the ringing tone trunk 13 to the voice information sound source 14. Such a method is, for example,
It is disclosed in JP-A-62-176255.

[0003]

In the conventional method of transmitting voice information to the calling subscriber who is calling the called subscriber, in the case of a subscriber exchange of the stored program control method, a program in a control unit of the exchange main body is used. Since it is necessary to realize the function by the above, there is a problem that the program needs to be changed in the exchange that is already in operation. Further, when transmitting individual information according to the subscriber, there is a problem that the subscriber data needs to be changed. Further, there is a problem that it is not possible to flexibly meet the needs because the above-described operation needs to be performed for each model of the exchange.

The present invention has been made to solve such a problem, and enables voice information from a sound source to be transmitted during a ringing tone in an analog general subscriber line of a public network without changing the subscriber exchange side. The purpose is to obtain a subscriber line voice information transmission device.

Switch and the subscriber circuit side of the subscriber times than switch to
A ringing tone detection circuit that detects the ringing tone from the line, and a switch
A response detection circuit for detecting the response of Chakukanyu's phone from the subscriber lines Chiyori subscriber circuit side, the subscriber electrodeposition from the switch
A disconnection detection circuit for detecting the disconnection of the subscriber telephone set from the subscriber line talking machine, the sound subscriber telephone controls the switch if the ringing tone is detected by the call ringer detection circuit
Subscriber telephone by switching and connecting to the voice information source
It starts the transmission of various kinds of audio information to machine, if the response of the destination subscriber telephone is detected by the response detection circuit or
Others are detected disconnection of the subscriber telephone set by the disconnection detection circuit
Subscriber times the subscriber's phone to control the switch in the case was
By switching and connecting to the roadside, each
In which Ru and a control circuit for stopping the delivery of the seed audio information.

[0006]

In the present invention, by inserting and connecting the subscriber line voice information transmission device of the present invention to the subscriber line, the voice information can be sent to each subscriber during the ringing tone without changing the subscriber exchange side. It can be transmitted accordingly.

1 is a block diagram showing an embodiment of a subscriber line voice information transmission apparatus according to the present invention. In FIG. 1, reference numeral 1 is a subscriber line voice information transmission device which is inserted and connected to a subscriber line connecting a subscriber circuit 8 of a subscriber exchange 9 and a subscriber telephone 10, and 2 is a ringer tone connected to a subscriber line. A ringing tone detecting circuit for detecting 3; a response detecting circuit for detecting a response of a called subscriber connected to the subscriber line; 4 for disconnection detecting circuit connected to the subscriber line for detecting disconnection of the calling subscriber;
Reference numeral 5 denotes a switch which is inserted into the subscriber line and connects the subscriber line to the voice information sound source 7. Reference numeral 6 controls the switch 5 based on the detection signals from the ringing tone detection circuit 2, the response detection circuit 3 and the disconnection detection circuit 4. It is a control circuit for controlling. And
It is configured to transmit voice information to the calling subscriber while calling the called subscriber.

Next, the operation of the embodiment shown in FIG. 1 will be described. First, the ringing tone detection circuit 2 detects a ringing tone when a call is made from the subscriber telephone set 10 to another subscriber, and notifies the control circuit 6 as a detection signal. Here, the control circuit 6 normally controls the switch 5 to which the subscriber telephone 10 and the subscriber circuit 8 are connected, connects the subscriber telephone 10 and the voice information sound source 7 and starts the voice information sound source 7. The voice information is sent to the subscriber telephone set 10. Then, this voice information is transmitted until the answer of the called subscriber or the disconnection of the calling subscriber.

Next, when the called subscriber responds, the response is detected by the response detection circuit 3 and is notified to the control circuit 6 as a detection signal. The control circuit 6 controls the switch 5, connects the subscriber telephone 10 and the subscriber circuit 8, and stops the voice information sound source 7. Now the call is ready.

When the calling subscriber disconnects during calling, disconnection of the subscriber's telephone set 10 is detected by the disconnection detection circuit 4 and is notified to the control circuit 6 as a detection signal. The control circuit 6 controls the switch 5, connects the subscriber telephone 10 and the subscriber circuit 8, and stops the voice information sound source 7. This is the recovery state.

In the embodiment shown in FIG. 1, the subscriber line voice information transmission device 1 is installed for each subscriber circuit.
A configuration in which the control circuit 6 is separated and the ringing tone detection circuit 2, the response detection circuit 3, the disconnection detection circuit 4, and the switch 5, which are detection circuits connected to a plurality of subscriber lines, are controlled by one control circuit 6. May be

[0012]

As described above, according to the present invention, the subscriber line voice information transmission device is inserted and connected to the subscriber line. Therefore, the voice information is transmitted during the ringing tone without changing the subscriber exchange side. Can be transmitted according to each subscriber, and a new voice information providing service can be easily realized.
