Next, the operation of the telephone having the above configuration will be described with reference to the flowchart.

The flow chart used in this embodiment mainly describes the operation of the telephone section 20.

First, one operation of the incoming call will be described.

There are two types of incoming call operation. One is an operation for making a call from a general subscriber and answering the call, and the other is an operation for making an LCR in the LCR data RAM 13.
This is an operation of storing data. This distinction is made by whether the modulated data for sending the LCR data from the line has been received after responding to the incoming call.

The operation at the time of this incoming call will be described with reference to the flowchart of FIG.

When the ringing signal is received from the line, the incoming call detection circuit 7 outputs a ringing tone from the ringer 8 and informs the telephone control unit 22 that the incoming call is being received. If a call is being received in step i1, the process proceeds to step i2, and if the handset 4 is not lifted, the process returns to step i1 to repeat steps i1 and i2. The operation ends when the incoming call ends while repeating steps i1 and i2. When the handset 4 is lifted in step i2, the process proceeds to step i3, the line is closed by the hook switch 1, and the switches C1 and D3 of the switching circuit 3 are turned on.
N, a path for transmitting and receiving a signal between the line and the modem 11 is created, and a signal is output from the telephone control unit 22 to the telephone side interface control unit 23, thereby giving an incoming command to the LCR unit 10, The side interface control unit 15 receives this and gives a signal to the data transmission / reception unit 12, and the data transmission / reception unit 12 operates the modem 11 to start the data reception operation. In this state, the signal received by the modem 11 is transferred to the data transmitter / receiver 12
If the modulated data for sending the LCR data is received from the line, the telephone control unit 22 is notified via the LCR side interface control unit 15 and the telephone side interface control unit 23.

When a call is received from a general subscriber, the above-mentioned modulated data is not received, so step i
Repeat 4 and i5 for 1 second, and move to step i6. In step i6, the switches C1 and D3 of the switching circuit 3 are turned off and the switches A1 and D2 are turned on to make a call between the handset 4 and the line in order to talk with a general subscriber. Move on to. Step i
Steps 7 and i8 are repeated while the handset is lifted and during a call. When it is detected in step i7 that the operation button 9 has been pressed, the corresponding operation (for example, hold or call recording) is performed.

When it is detected in step i8 that the handset 4 is placed, the process proceeds to step i9 to open the line by the hook switch 1 and turn off all the switches of the switching circuit 3 to end the operation.

When a call is received from the LCR data update center, this is detected in the repetition of steps i4 and i5, and the process proceeds to step i11. Step i
11 and i12 are repeated while data is being received. In step i11, the data transmission / reception unit 12 controls the data reception protocol from the center via the modem 11 and sequentially stores the received LCR data in the LCR data RAM 13. . When the reception of the LCR data ends, the data transmission / reception unit 12 stops the operation of the modem 11, and
This is notified to the telephone control unit 22 via the LCR side interface control unit 15 and the telephone side interface control unit 23. When the telephone control unit 22 detects the end of data reception in step i12, the process proceeds to step i9, the hook switch 1 opens the line, and all the switches of the switching circuit 3 are turned off to end the operation.

Next, the operation at the time of calling will be described with reference to the flowchart of FIG.

When the user wants to make a call, the handset 4 is lifted, this is detected at step j1 and the process proceeds to step j2. At step j2, the line is switched to hook switch 1
The switch circuit 3 is closed by turning on the switches A1 and D2 of the switching circuit 3.
N, enabling communication between the handset 4 and the line and moving to step j3. At step j3, it is judged whether or not the dial button of the operation buttons 9 has been pressed. If the dial button has been pressed, step j4 is skipped. If not, step j4 is skipped and step j4 is skipped.
Go to 5. In step j4, the dial data for the pressed dial button is sent to the LCR unit 10 via the telephone side interface control unit 23, and the LCR unit 10
Then, by the LCR side interface control unit 15,
This is received and sent to the LCR determination unit 14.

Each time the LCR determination unit 14 receives dial data, the received dial data string and LC
The contents stored in the R data RAM 13 are compared and LCR
Make a decision. When the dial data is received up to a digit that can be determined, an appropriate carrier is selected, and a dial data string that uses the carrier is sent to the telephone unit 20 via the LCR side interface control unit 15. If the dial data is not received up to the digit that can be judged,
The LCR determination unit 14 does not output the dial data string.
Further, when the LCR data is not stored in the LCR data RAM 13 and after the LCR determination is performed once and the carrier is selected, the LCR determination unit 14 keeps the received dial data as it is via the LCR side interface control unit 15. Send to 20. In the telephone section 20, the LCR section 1
The telephone-side interface control unit 23 receives the dial data sent back from 0.

At the step j5, the LC
It is determined whether or not the dial data string is received from the R section 10, and if it is received, the process proceeds to step j6,
If not received, it skips step j6 and moves to step j7. In step j6, the above step j
The dial data string received at 5 is sequentially sent to the dial circuit 6, and when the dial pulse is output, it is sent to the line through the hook switch 1, and when the DTMF signal is output, the line is sent through the speech network 2. Send to.

Next, move to step j7, and press the operation button 9
When it is detected that a button other than the dial button has been pressed, the process moves to step j10, and the corresponding operation (for example, hold or call recording) is performed. If the operation button 9 is not pressed in step j7, the process proceeds to step j8. In step j8, it is detected whether or not the handset 4 is placed. If the handset 4 is not placed, the process returns to step j3 to repeat the above operation. Step j8
When it is detected that the handset is placed at step j9, the line is opened by the hook switch 1 and all the switches of the switching circuit 3 are turned off to complete the operation.

Next, the operation of the service center for transmitting the recorded data corresponding to the held melody and the response message will be described with reference to the flowchart of FIG.

First, in step l1, it is determined whether or not there is an incoming call from the user's telephone. If there is an incoming call, the process proceeds to step l2. In step l2, the line is closed, and the process moves to step l3. In step l3, for example,
Play message 1 such as "This is a service center. Please press the desired number." After the message is over, move to step l4. In step 14, the process waits until one of the DTMF signals 0-9 is received from the user, and when this is received, the data to be transmitted is selected. The service center always stores 10 kinds of recorded data corresponding to digitally recorded hold melody and response message, and the contents of the hold melody and response message are known to the subscriber in advance. Then, for example, the transmission data for the DTMF signals 0 to 4 is the data of the hold melody, the DTMF signal 5
Information regarding the type that the transmission data for ~ 9 is the data of the response message is also stored.
After receiving the DTMF signal and selecting the data, in step l5, send message 2 such as "I will send you the data. Please press the # button." Move to 16. In step l6, the user waits until the DTMF signal # indicating the start of reception is received, and when this is received, the process proceeds to step l7 and the attribute data including the type of the recording data selected above is transmitted. . Next, the process proceeds to step 18 and the recording data selected above is transmitted. When all the data has been transmitted, the process moves to step 19 to open the line and end the operation.

Next, the receiving operation of the recorded data on the telephone side will be described with reference to the flowchart of FIG.

When the service center call button of the operation button 9 is pressed to receive the recorded data, this is detected in step k1 and the process proceeds to step k2. At step k2, a confirmation command for confirming whether or not the LCR data is downloaded is sent to the LCR unit 10 via the telephone side interface control unit 23. LCR
Upon receiving the confirmation command, the LCR determination unit 14 of the unit 10 reads the LCR data RAM 13 and checks whether or not the LCR data is stored. Then, the confirmation result command including the information indicating whether or not the LCR data is stored is returned to the telephone unit 20 via the LCR side interface control unit 15. In the telephone section 20, the telephone side interface control section 23 receives this and sends it to the telephone control section 22. If it is determined that the LCR data is stored, the process proceeds to step k3. If it is determined that the LCR data is not stored, it is determined that the subscriber is not a legitimate subscriber who can receive the recording data from the service center. Then, the operation ends as an error.

At step k3, the line is closed by the hook switch 1, and the process goes to step k4. Step k4
Then, first, after waiting for about 3 seconds before dialing, the dial data string indicating the service center number stored in advance in the telephone control unit 22 is sequentially sent to the dial circuit 6, and the dial pulse or DTMF like the dialing operation number is sent. The signal is sent to the line, and the process proceeds to step k5. In step k5,
Turn on the switch D4 of the switching circuit 3 to turn on the speaker 5
So that you can hear the line signal, move to step k6,
The operations of steps k6, k7 and k8 are repeated. By the above, the telephone is connected to the service center that provides the recorded data, and the user presses the dial button to send the DTMF signal according to the message, select the recorded data to download, and then press the # button to record the recording. The data is downloaded.

After listening to the message 1 from the service center during the repeated operation of steps k6, k7 and k8, the user presses the operation button 9 to dial the dial button 0.
When ~ 9 is pressed, it is detected at step k6 and the process proceeds to step k7. At step k7, dial data is sent to the dial circuit 6 and D corresponding to the pressed dial button is pressed.
The TMF signal is sent to the line via the speech network 2.

After that, while listening to the message 2 from the service center during the repeated operation of steps k6, k7 and k8, when the user presses the # button with the operation button 9, it is detected in step k8, Move to k9. In step k9, # dial data is sent to the dial circuit 6, the # DTMF signal is sent to the line through the speech network 2, and the process proceeds to step k10. At step k10, the switch D4 of the switching circuit 3 is turned off.
Then, the switches C1 and D3 are turned on to enable communication between the modem 11 and the line. Further, a reception start command is transmitted to the LCR section 10 via the telephone side interface control section 23, and the LCR side interface control section 15 of the LCR section 10 receives the command, and the data transmission / reception section 12
Send to. Upon receiving this reception start command, the data transmission / reception unit 12 starts the operation of a series of protocols for receiving the attribute data and the recording data.

First, the modem 11 is put into operation,
Wait for data from the line. When the carrier indicating the start of communication is received from the center and then the attribute data is received, the data transmitting / receiving unit 12 receives it by the modem and sends it to the telephone unit 20 via the LCR side interface control unit 15. In the telephone section 20, the telephone side interface control section 23 receives it and sends it to the download control section 24. In step k11, the download control unit 24 waits until the attribute data is received, and when this is received, the process proceeds to step k12. Step k12
Then, since the data to be received later is stored in the recording RAM 31 of the recording unit 30, according to the received attribute data,

Operation of the LCR side interface control unit 1
An end command is sent to the telephone unit 20 via 5. Telephone section 2
The telephone side interface control unit 15 of 0 receives this and sends it to the download control unit 24. Upon receiving the end command in step k15, the download control unit 24 moves to step k16. At step k16, the download control unit 24 sends a stop command to the recording / reproducing unit 30 to end the storage operation, and at the same time, receives the final address of the storage from the recording / reproducing unit 30, and the attribute of the stored data. Is sent to the recording / reproducing control unit 25 to be stored therein, and the process proceeds to step k17. At step k17, the line is opened by the hook switch 1, all the switches of the switching circuit 3 are turned off, and the series of operations is completed. Next, a method of reproducing recorded data received from the service center by the above operation will be described.

First, the reproduction of the hold melody will be described.

During a call after incoming or outgoing, the line is closed by the hook switch 1 and the switches A1 and D2 of the switching circuit 3 are turned on. Operation button 9 at this time
When the hold button is pressed in, the input section 21 inputs it and a signal is sent to the telephone control section 22.

The telephone control unit 22 turns off the switches A1 and D2 of the switching circuit 3 and turns on the switches B1 and B4 to send a signal from the recording / playback unit 30 to the line.
A path for outputting the same signal to the speaker is also created, and a signal is output to the recording / reproducing control unit 25 to request the reproduction of the hold melody. The recording / playback control unit 25 receives the signal from the download control unit 24 so that the hold melody has a RA for recording.
Whether it is stored in M31 and, if so, the final address is stored. When the hold melody is stored in the recording RAM 31, the start address, end address, and reproduction command thereof are sent to the recording / reproducing unit 30, and the recording RAM 31 is recorded.
The data stored in is sequentially read, converted into an analog signal hold melody, and sent to the line. Also,
If the hold melody is not stored in the recording RAM 31, the start address, the end address, and the reproduction command corresponding to the melody of the reproduction ROM 32 are sent to the recording / reproducing unit 30, and the data stored in the reproduction ROM 32 are sequentially read. Convert it into a hold melody of an analog signal and send it to the line. Then, when the reproduction of all the data in the recording RAM 31 and the reproduction ROM 32 is completed, the same contents are reproduced again.

Next, reproduction of the response message will be described.

In the answering mode, when there is a predetermined number of incoming calls from the outside line (for example, four times), the telephone control unit 22 detects this, the hook switch 1 closes the line, and the switching circuit 3 switches the switch B1. And turn on D5
Then, the line and the signal path of the recording / reproducing unit 30 are formed. Then, the telephone control unit 22 outputs a signal to the recording / reproducing control unit 25 to request the reproduction of the response message. Recording / playback control unit 25
Stores whether or not the response message is stored in the recording RAM 31 according to the signal from the download control unit 24 and, if stored, the final address thereof. When the response message is stored in the recording RAM 31, the start address, end address and reproduction command are sent to the recording / reproducing unit 30,
The data stored in the recording RAM 31 is sequentially read, converted into an analog signal response message, and sent to the line. If the response message is not stored in the recording RAM 31, the start address, the end address, and the reproduction command corresponding to the response message in the reproduction ROM 32 are sent to the recording / reproducing unit 30, and the data stored in the reproduction ROM 32 is stored. Are sequentially read out, converted into a response message of an analog signal, and transmitted to the line. And
When the reproduction of all the data in the recording RAM 31 and the reproduction ROM 32 is completed, the analog signal from the line is converted into digital data and recorded in the recording RAM 31 as a matter.

As described above, the recording data corresponding to the hold melody or the response message from the service center is received by the simple operation and stored in the recording RAM 31.
If necessary, they are sent to the line as a hold melody or response message, so you can select a high-quality hold melody or response message from many, even if you do not record the melody or response message yourself. In addition, when servicing a new melody or response message, the user can immediately use it by simply replacing or increasing the accumulated data in the service center.

Moreover, in this embodiment, the modem and the response message etc. are digitized and recorded, and since the invention is applied to the answering machine with the LCR function equipped with the recording circuit for reproducing this, a special additional circuit. The above functions can be realized at low cost without the need for.

It is needless to say that the present invention can be similarly applied to a telephone having no LCR function.

Further, although the recording and reproduction of the hold melody and the response message have been described in the above-mentioned embodiments, the present invention is not limited to these, but can be applied to a ring tone and various voice guidance.

[0072]

As described above, according to the present invention, digital data such as a hold melody and a response message are received and demodulated from a service center by a simple operation, stored in a memory, and reproduced as necessary. It can be sent as a hold melody or response message. Therefore, even if the user does not record the melody or response message by himself / herself, a high-quality hold melody or response message can be selected from many lines. Can be sent to.

Moreover, when the present invention is applied to a telephone having an LCR function, the above function can be realized at low cost without providing a special additional circuit other than the reproducing means and the memory.

Further, it is possible to restrict the telephone set which receives the recording digital data such as the held melody and the response message from the service center, so that only the person who subscribes to the service can receive the recording digital data. Can be memorized.
