Abstract

PURPOSE:To recognize a called caller name by displaying a name stored in a memory corresponding to a caller number when the caller number stored in the memory is coincident with the caller number received via an ISDN line. CONSTITUTION:In the case of an incoming call, a caller number included in a call setting message, that is, a caller opposite number is detected by a line monitor 3 and stored in a memory 15. The operation of recognizing a caller while a called party is absent is as follows; A print command is given to a control circuit 14, then the number of the caller is discriminated whether or not the number is coincident with the caller number stored in advance in the memory 15. When coincident, the opposite caller number and a name corresponding thereto are printed out on a recording paper sheet 17 by an output circuit 16. When it is discriminated that the received and stored caller number is dissident with the caller number stored in advance in the memory 15, then only the received and stored caller number is printed out.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to ISDN (Continued digital communication network Intel)
rated 5service DegiLal Ne
The present invention relates to an ISDN communication device that performs communication using a work) line.

BACKGROUND OF THE INVENTION In traditional analog telephone networks, it is possible to record the caller's voice by means of a so-called answering machine when the called party is not present; This increases communication charges and makes it impossible to easily know the caller who made the call when the user was absent.

SUMMARY OF THE INVENTION An object of the present invention is to provide an I5DN communication device that allows the calling party to be easily known even when the called party is not present.

SUMMARY OF THE INVENTION The present invention provides an ISD that sends the calling party's calling number to the called party.
In the N communication device, there is a memory for storing the calling party's calling number and the calling party's name in correspondence with each other, and when the calling party's calling number is received, the calling party's calling number is stored in the memory. means for detecting whether the number is a previously stored number; and, in response to the output of the detecting means, when the calling number of the caller is stored in the memory, the number is stored corresponding to the calling number. and means for displaying a caller's name.

Operation According to the present invention, a calling party's calling number and the calling party's name are stored in correspondence with each other in the memory.

When the called party is absent, for example, when a call is received over the ISDN line, the calling party's calling number is received and it is determined whether the calling number is the calling number stored in memory. To detect. When the received calling number is a calling number previously stored in memory, the name of the caller corresponding to the calling number is displayed by printing it on recording paper, or by displaying it on a liquid crystal display element or cathode ray tube. It can be visually displayed using a method such as the above, or it can be displayed as an audio output using a voice synthesis circuit. In this way, even when the called party is absent, the name of the caller who made the call can be easily known.

Embodiment FIG. 1 shows the entire block opening of an embodiment of the present invention. Terminal R1 has a communication tube F+! It is connected to a line monitor 3 of the device 2 via a line 4, and this line monitor 3 connects to a DSU (Digital Service) via a line 5.
ce Unit) circuit 6, and further connected to the I5DN line 7. The terminal device 1 includes a processing circuit 8 realized by a microcomputer or the like, a facsimile means 9 for performing facsimile communication, a handset 10 for performing telephone communication, and the like.

When making a call using the terminal 1, the processing circuit 8 sends a signal 13 from the line 4 to the communication line 7, including the calling number 11 and the number 12 of the called party, as shown in FIG. Derive. The line monitor 3 monitors and detects the calling party 1>calling number received via the ISDN line 7. A signal representing the caller's calling number detected by the line monitor 3 is given to a control circuit 14 realized by a microcomputer or the like. This control circuit 14
A memory 15 and an output circuit 16 are connected to. The output circuit 16 is, for example, a printer, and is capable of printing and displaying information on a recording paper 17.The output circuit 16 may also be a visual display means including a liquid crystal display element, a cathode ray tube, or the like. Alternatively, when the call is made via the TSDN four-wire 7, which may also be an audio output display means comprising a voice generation circuit, the calling number of the said calling party is included in the call setup message. It is included as an information element in the ISDN layer 3 procedures.

FIG. 3 is a diagram showing the contents of the memory 15.

In this memory 15, calling numbers of callers who may be called and names of callers corresponding thereto are stored in separate correspondence. The caller's name may be, for example, a company name, an individual's name, or the name of the department to which the caller belongs.

The operation upon receiving a call will be explained with reference to FIG.

The process moves from step n1 to step n2, and when it is an incoming call, the process moves to step n3, where the line monitor 3 detects the calling number of the calling party included in the call setting message, that is, the number of the called party, and stores it in the memory 15.・A.

The 511ffi describes the operation for knowing the calling party when the called party is absent. Stella 7
” rn 1 to step f “12, control circuit 1
When the printing command is issued in step 4, in step 113, it is checked whether the number of the called party who received the call matches the calling number stored in advance in the memory 15 as shown in FIG. If they match, step rn
4, the other party's name, 7) calling number, and the corresponding name are printed and displayed on recording paper 17 by output circuit 16.

In step rn3, the caller's ISD
The calling number received and stored via the N line is
As shown in the figure, if it is determined that the calling number does not match the calling number stored in advance in the memory 15, in step m5, only the received and stored calling number of the other party is printed and displayed.

In this manner, in step n14 described above, when the received calling party's calling number matches the pre-stored calling number, the name of the calling party corresponding to the stored calling number is displayed. Now, even when the called party is not present, the person who made the call can be called by l! 1JPf! can be known.

As another embodiment of the present invention, in Stellar 7 RN 4,
Only the name of the caller may be printed.

As another embodiment of the present invention, the processing circuit 8 is provided with touch keys corresponding to each song of the called party, and the memory is
The calling number stored in 5 or the like may be derived to the ISDN line 7 to make a call. Further, as another embodiment, the calling number stored in the memory 15 is used, and the abbreviation key provided in the processing circuit 8 and 'Q' are used.
By operating a single or multiple digit numeric key that individually corresponds to the number, the caller number stored in the memory 15 is used to make a call via the ISDN line 7. Good too.

Effects of the Invention According to the present invention, when the calling number stored in the memory matches the calling number received via the ISDN line, the calling number is stored in the memory corresponding to the calling number. Since the name of the called party is displayed, it is possible to easily know the caller who made the call even when the called party is not present. It is possible.
