BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital telephone connected to an ISDN line, and more particularly to a function of editing caller ID information for identifying the other party in the case of an incoming call within a terminal device and notifying the user.

0002

2. Description of the Related Art Conventionally, this type of digital telephone has been equipped with a display, a caller ID information receiving section, a display information editing section, and an I/O
The caller ID information received from the SDN line was edited and displayed in a form that the user could recognize. Furthermore, in a private exchange network such as a PBX, a host computer supplies information on the other party to a terminal via the PBX.

0003

[Problems to be Solved by the Invention] However, with the above-mentioned conventional digital telephone, only the telephone number of the other party is determined by the caller ID information at the time of receiving a call, so it is not possible to know what the name of the other party is. Also, without a host computer, information on the other party cannot be obtained.

The present invention has been made in view of the above-mentioned conventional circumstances, and therefore, an object of the present invention is to provide a novel digital telephone device capable of solving the above-mentioned problems inherent in the conventional technology. There is a particular thing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a preferred embodiment of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.

Referring to FIG. 1, a control section 1 controls the operation of the digital telephone device according to the present invention.
It is connected by bus to the following components. S-INF2
is an interface that takes in an ISDN line, and has the function of separating the D channel, which is a signal channel, and the B channel, which is an information channel, and is directly connected to the LAP-D 3 and the telephone circuit section 9, and is also It is connected. The LAP-D3 has a function of transmitting/receiving information on the D channel, which is a control channel of the ISDN line, and is connected to the control unit 1 by a bus. The caller ID information receiving unit 4 is connected to the control unit 1 by bus, and is further connected to the information search/read unit 5, and receives the caller ID (caller ID) from the incoming call information sent from the D channel of the ISDN line when a call is received.
is selected and passed to the information search/read unit 5. The information search/readout section 5 is connected to the control section 1 via a bus, and is also connected to the electronic telephone directory section 6 and the display information editing section 7, and receives caller ID information and uses that information as a clue to search the corresponding information from the electronic telephone directory 6. Search your data. If applicable data exists,
The information search/read unit 5 reads out the subscriber name and address associated with the data from the electronic telephone directory 6 and passes it to the display information editing unit 7. If the corresponding data does not exist, a message to that effect is passed to the display information editing section 7. The electronic telephone directory section 6 has a function of reading information from a CD-ROM telephone directory, and is connected to the information search/read section 5. The display information editing section 7 is connected to the control section 1 via a bus, and re-edits the message for outputting the information from the information search/reading section 5 to the display 8 and outputs it to the display 8. The display device 8 is connected to the control section 1 via a bus, and displays the display information output from the display information editing section 7 to notify the user. Telephone circuit section 9
is connected to the control unit 1 via a bus, and is also connected to the B channel of the S-INF 2 to realize a telephone conversation function.

Next, the operation of the digital telephone device according to the present invention will be explained.

In the digital telephone device of the present invention, the caller ID information sent from the ISDN network when a call is received is separated from the incoming message by the caller ID information receiving unit 4, and based on that information, the caller ID information is implemented in the electronic telephone directory unit 6. Using the subscriber number as a clue, the name and address of the other party are read out from the CD-ROM telephone directory by the information retrieval/reading section 5 and displayed on the display 8 via the display information editing section 7.

[0011]

[Effects of the Invention] As explained above, according to the digital telephone device according to the present invention, information recorded in the telephone directory such as the name and address of the caller can be confirmed from the caller ID information at the time of receiving a call on the display. Since you can answer incoming calls, you don't have to answer calls from unknown parties such as wrong calls or harassing calls, and if you store customer information on the CD-ROM in advance, the recipient's information will be displayed on the display when you receive a call. Since the phone appears on the screen, you can have the effect of smoothly answering the phone.
