However, the terminal equipment used in the above-mentioned systems only stores and displays the received calling party's subscriber number on a visual display, so that the called party cannot It is a hassle to confirm the caller on the display device and then pay for the processing of the call.

An object of the present invention is to eliminate the above-mentioned problems, to store a specific subscriber number in advance in a terminal device, and to specify the subscriber number of the calling party received in the terminal device and the stored specific subscriber number when a call is received. It is an object of the present invention to provide a terminal device that can reduce the annoyance of a called party by checking the number and informing the called party of the caller's classification by visual and audible signals.

[Means for solving problems]

The terminal device of the present invention comprises a receiving means for receiving a subscriber number of a calling party sent from an exchange when a call is received, a storage means for storing a plurality of subscriber numbers, and a subscriber number received by the receiving means. It is constituted by a collation means for collating the number and the subscriber number stored in the storage means, and a display means for distinguishing and displaying matches and mismatches in the collation means.

Further, in the terminal device of the present invention, in the above configuration, the storage means stores subscriber numbers in groups, and the display means stores the subscriber numbers that are matched in the matching means. and display means for distinguishing and displaying each subscriber number and the unmatched subscriber number.

In the above configuration, a subscriber who has a terminal device of the present invention can store the subscriber numbers in a batch or in groups in advance in the terminal device. incoming calls from subscribers with subscriber numbers that are not stored and subscribers with subscriber numbers that are not stored can be recognized by differentiated visual and audible indications.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, in which the terminal device is a digital telephone connected to a digital exchange. This digital telephone has an interface circuit (hereinafter referred to as PHI) 1 that sends and receives digital signals to and from an exchange, and a bidirectional analog-to-digital converter circuit (hereinafter referred to as AD) 2 that connects one side to the PHI and the other to the handset 3. , a serial interface circuit (hereinafter referred to as 8I) that transmits and receives serial data between PHIl and PHIl.
4 and a fixed memory circuit (hereinafter referred to as ROM) that stores the program.
) 5 and an arbitrary memory circuit (hereinafter referred to as RAM) that stores data.
6, a microprocessor (hereinafter referred to as CPU) 7 connected to ROM 5 and RAM 6, an input circuit (hereinafter referred to as INP) 8 connected to this CPU 7, and an output circuit (hereinafter referred to as OUP) 9 connected to CPU 7, IN
The dial circuit (hereinafter referred to as DIAL) 10 connected to P8 and the visual display connected to 0UP9 are the same (OUP
an audible sound generator SP connected to
4. Note that SI4 is connected to INP8 and 0UP9 to perform parallel transfer of input data to CPU 7 and output data from CPU 7, respectively. Furthermore, the subscriber numbers stored in this telephone are in two groups, the first group and the second group, and the subscriber number and this group can be displayed on the visual display, and the audible tone generator 8P
In addition to the normal ringing tone when a subscriber receives a call, the system generates a distinct ringing tone when the above two groups of subscribers receive a call.

In the above configuration, in addition to the program that performs normal processing of control data sent and received with the exchange, the kLOM 5 also contains a program for storing subscriber numbers, and a calling party that is sent from the exchange when a call is received. A verification processing program is stored that verifies the subscriber number stored in the RAM 5 with the subscriber number stored in the RAM 5 and drives a visual display and an audible sound generator SP in accordance with the verification result.

FIG. 2 is a diagram showing the allocation of subscriber numbers stored in RAM 6.
Addresses 101 to 120 as the first group and second group, respectively.
An example is shown in which 20 subscriber numbers can be stored in each of addresses 201 to 22o.

Next, proceeding with the explanation of the operation shown in Figure 1, the function key F
K1 is a display key for the subscriber number stored in RAM6;
With each change, the address and stored subscriber number are sequentially displayed on the visual display through the first and second groups. The subscriber then displays the address he wishes to remember in function-11'. The function key FK is a write instruction key, and by operating this key and operating DIALIO, the dialed number is written to the displayed address and the written number is displayed.

The function key FK3 is a key for erasing the memorized subscriber number, and it is displayed on the function key PK, and by operating the function key FK3 after giving a writing instruction to the function key PK, The memory of the subscriber number of the displayed address is erased. By combining the above operations, the first and second groups
It is possible to store the subscriber number that the group wants to store.

Therefore, when incoming call data is sent to this telephone from the exchange, PH11 recognizes that it is control data and transfers this data to SI4. Send it to CPU7 via INF8.

The CPU 7 extracts the calling party's subscriber number from the format of the incoming call data, and compares this subscriber number with the subscriber number read by mhM6-tL and the like. This verification is performed by a normal verification method in which the subscriber number at address 101 is read out, and if there is a mismatch, the subscriber number at the next address 102 is read out and repeated at address 220t. If a match is found during this process, an output corresponding to the matched group is provided to the visual display and the audible display SP via 0UPQ. If a match is not obtained with all stored subscriber numbers, normal paging output is provided to both displays via 0UP9.

Therefore, the called subscriber can immediately make an appropriate response without confirming the calling subscriber number from the call display and ring tone. The call from this subscriber is made by dialing after going off-hook and operating the function key FK4.

〔Effect of the invention〕

As explained above, in the present invention, when a call arrives, the terminal device compares the pre-stored subscriber number with the calling subscriber number, and visually and audibly informs the group of callers.
This has the effect that the called subscriber can take appropriate action at the same time as the call is made.
