Embodiments of the home telephone device according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram of a main part of an embodiment of a home telephone device according to the present invention. In the figure, reference numeral 1 is a telephone line, and 2 is an automatic incoming call unit, which detects a calling signal from the telephone line 1 and automatically receives an incoming call to establish a call state with a terminal device which is a caller. A PB signal detector 3 detects the PB signal from the calling terminal. A storage unit 4 stores a code for setting / updating restrictions such as a secret code and data for restricting the secret code. 5 is a discriminating unit, which is the P from the calling terminal.
The data based on the B signal and the data read from the storage unit 4 are compared and discriminated and a signal is output. 6 is a PB signal generator,
It generates and sends a PB signal in response to the calling terminal. Reference numeral 7 is a voice synthesizer, which generates and sends a voice signal of a response to the calling terminal. A control unit 8 controls each unit of the apparatus. Reference numeral 9 denotes a speech path selection switch, which is controlled by the control unit 8 and selectively connects circuits.

Next, the operation of the home telephone device according to the present invention will be described with reference to the communication sequence of FIG. First,
A case where the personal identification number is updated from a public telephone (push-button telephone) when going out (FIG. 2, (a)) will be described. When the dial number of the home telephone device is input by operating the dial button (ST1), the automatic call receiving unit 2 detects the ringing signal input through the telephone line 1 and the predetermined number of times, for example, the bell
After 20 times (about 1 minute), the DC loop is closed and an incoming call is received automatically, and a response message such as "I'm away now,
Please try your call later "(ST2). Next, a code that has been set in advance for setting the personal identification number, for example,
When "# 101 *" is input (ST3), the PB signal corresponding to the input code is transmitted and demodulated by the PB signal detection unit 3 into a number or the like. The data such as the detected number is compared and discriminated by the discrimination unit 5 with the code read from the storage unit 4,
If the entered code matches the code for setting the personal identification number, the home telephone device enters the personal identification number setting mode. Then, for example, a response message such as "Confirmed, please have a number" is returned from the voice synthesis unit 7 (ST4). Therefore,
The password to be updated, for example, "1234" and the "registration" code "*" are input. This input is sent as a PB signal (ST5), processed by the PB detection unit 3, the determination unit 5, and the control unit 8 via the speech path selection circuit 9, and the storage unit 4 receives the code "*" for "registration". Will be registered as a new number. Then, a confirmation message such as "registered personal identification number 1234" is returned (ST6), and the personal identification number update ends. After that, the data is saved until the next update is performed.

Next, description will be made on the case of updating regulations such as a personal identification number from a dedicated external device such as an office (FIG. 2B). With this device, if you enter the dial number of your home telephone device in advance, the secret code for updating, etc., check the contents on the display etc. and press the "Start" button, the required code etc. will be added automatically. You can send a signal to update the setting. The transmitted signals are "0-9, A-D, #,
* "And other PB signals. First, when the dial number is transmitted (ST7), the home telephone device automatically receives an incoming call, returns a predetermined message, and then enters a standby state. The external device confirms the standby state, and sends out a code for instructing the security code update, for example, "ABCD300 *" (ST8). This signal is detected by the PB signal detection unit 3, and the discrimination unit 5 compares and discriminates it with the code from the storage unit 4. It is determined whether the code is the same as the code for updating the personal identification number determined for the dedicated device, and the PB signal generator 6 returns a response PB signal "ABCD300 #" based on the determination result (ST9) to update the personal identification number. Enter the mode. Next, by confirming this response signal, a signal obtained by adding a predetermined code to the personal identification number "1234" to be updated,
For example, a signal "DCBA1234 *" is transmitted (ST10). Upon receiving this signal, the home telephone device calls "12.
34 "as a new number in the storage unit 4, and a PB signal such as a confirmation response signal" DCBA1234 # "is returned (ST11). Confirm this signal, and finally, the end signal "*
"**" etc. is sent (ST12) to disconnect the line. The update of the personal identification number has been described above, but similarly, security-related and other regulations can be updated.

[0009]

As described above, in the home telephone device according to the present invention, the regulation such as the personal identification number can be updated from an external device such as a public telephone or an office. It responds to the operation from the public telephone with a message by voice synthesis and PB to the dedicated external device.
Since it responds with a signal, it is possible to reliably update regulations even from a remote location.
