DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described with reference to the drawings. The telephone device of the present embodiment corresponds to a calling telephone number display service (pre-communication information notification service) currently provided by Nippon Telegraph and Telephone Corporation (NTT). In this service, a telephone number (caller number) of a telephone device (information receiving terminal) of a calling party is notified to a telephone device of a called party before a central office transmits a calling signal.

This telephone number sending process will be described with reference to the time chart of FIG. When the caller's telephone device makes a call, the central office inverts the polarities of the two telephone lines L1 and L2. Then, the central office sends a CAR (information receiving terminal activation signal) to the telephone equipment of the called party. The telephone device of the called party receiving the CAR goes off-hook and forms a DC loop. At this time, the telephone device does not ring even when receiving the CAR.

The central office detects the formation of this DC loop as a primary response signal and sends out a modem signal (information signal) including the calling party number to the telephone equipment of the called party. Upon receiving the modem signal, the telephone equipment of the called party cuts off the DC loop and sends a reception completion signal to the central office. When the telephone station detects the reception completion signal, it determines that the telephone number transmission processing has been completed and transmits a normal call signal (IR). The telephone device that has received the call signal notifies the incoming call by ringing. In this way, the called party can be notified of the calling party's telephone number before ringing.

FIG. 2 is a block diagram showing a configuration of a main part of the present invention. (1) is a line switch, which is connected to a telephone line, and releases (closes a DC loop) and closes (forms a DC loop) the line. (2) is a 2-wire / 4-wire circuit, which performs 2-wire / 4-wire conversion. (3) is a handset, which has a speaker (31) and a microphone (32).

(4) is a polarity reversal detection circuit which is connected to the telephone line and detects the reversal of the polarity of the telephone line.
(5) is an incoming call detection circuit, which is connected to a telephone line and detects an incoming call (call signal) and CAR. (6) is a primary response detection circuit, which detects whether or not a DC loop is formed by detecting the magnitude of a current flowing through a line connected to a telephone line.

(7) is a caller number detecting circuit which detects the telephone number (caller number) of the caller from the modem signal input via the 2-wire / 4-wire circuit (2). Output to the control circuit (9). (8) is a DTMF detection circuit,
The DTMF signal input through the 2-wire / 4-wire circuit (2) is detected and output to the control circuit (9).

(9) is a control circuit composed of a microprocessor, and a ROM (1) storing an operation program.
Each part is controlled based on 0). (11) is a RAM for storing information necessary for the operation of the control circuit (9), such as a fake caller number and a fake call voice. A hook switch (12) detects whether or not the handset (3) is placed on a handset placing section (not shown). Here, a state in which the handset (3) is placed on the handset placing section is called on-hook, and a state in which the handset (3) is not placed on the handset placing section is called off-hook.

(13) is a bell which outputs a ringing tone when an incoming call is received. (14) is a liquid crystal display means for displaying a telephone number, a name and the like. (15) is an input means, which includes a ten-key (151) for inputting a telephone number and a fake bell key (152) for operating a false incoming call notification.

Next, the main operation of the present invention will be described. FIG.
Is a flowchart showing the operation of the control circuit (9).
The control circuit (9) determines whether an incoming call has been received (S1) or whether the false bell key (152) has been pressed (S2).
To monitor.

When there is an incoming call (Y in S1), the control circuit (9) monitors whether or not a remote mode has been set (S1).
3). The remote mode is a mode in which the telephone device is controlled from an outside line. For example, when the user forgets to set the answering machine, the user sets the answering machine by a predetermined remote operation from a pay phone. In the case of this embodiment,
If a calling signal is received for a predetermined time (it sounds a predetermined number of times), it is determined that the remote mode has been set. If the control mode is not the remote mode (N in S3), the control circuit (9) performs a normal call or incoming call termination processing (S3).
4).

When the control mode is the remote mode (Y in S3), the control circuit (9) closes the line (S5). And
The control circuit (9) monitors whether or not a predetermined false bell request signal has been received from the telephone line within a predetermined time (S6). If a false bell request signal is not received (N in S6), the DC loop of the telephone line is released (S7), and the process returns to step S1.

In step S6, for example, a person requesting a false ringing transmits "8 #" indicating a false bell request signal to the telephone apparatus by another telephone apparatus using a DTMF signal. When the control circuit (9) receives this, the DC loop of the telephone line is released (S8), and the reception of the false bell request signal is terminated.

After a predetermined time T1 (S9, S1
0) The fake caller number stored in the RAM (11) is displayed to impersonate the caller number display by the calling telephone number display service (S11). The fake caller number is not limited to a number, and may be, for example, a character indicating that the caller number cannot be displayed because it is a call from a public telephone (for example, “KOUSHU”).

The bell (13) is caused to ring in order to pretend to receive a call signal (S12).

Further, in order to pretend to be a call, the telephone line is not closed even if the handset (3) is lifted out of the handset placing portion within a predetermined time T2 (S).
13, S14, S15). And handset (3)
Is lifted (Y in S13), the false sound is stopped (S16), and the false call voice stored in the RAM (11) (for example, "There was an urgent call from the hospital") Output from (31) (S1
7). If the handset (3) is placed on the handset placing portion (S18), the display of the caller number in step S11 is deleted (S19), and the process returns to step S1.

When the control circuit (9) detects in step S2 that the false bell key has been pressed, the operation proceeds to step S9. And, as when receiving the false bell request signal,
Pretend to be calling party number display by calling phone number display service, pretend to receive a call signal, pretend to be a call.

In this way, the call by telephone is falsified. This false call corresponds to the calling telephone number display service.

It should be noted that the method of notifying the incoming call is desirably the same as the method of notifying the normal incoming call, and is not limited to sounds such as ringing, but may be light or vibration.

[0027]

As described above, a false incoming call notification can be made by operating a predetermined key or operating another telephone device. This can be used to create a reason to escape the situation you want to avoid.
