Description

[Detailed Description of the Invention] This invention provides a subscriber line and a telephone, a telephone terminal,
Regarding a terminal calling device for disconnecting a terminal such as a simple data terminal, the device attempts to distinguish the originating subscriber number sent by If/IK and call a predetermined terminal.

Previously proposed technologies of this type include caller ID display. When a telephone connected to a subscriber line receives an incoming call, this system receives the subscriber number information sent from the exchange network and displays the caller's telephone number on the telephone's numeric display. be. However, unlike the case where only one telephone set is connected to one subscriber line, when multiple terminals can be connected to one subscriber line, there are multiple terminals connected to multiple subscriber lines. In cases where interconnection is possible, simply displaying the calling party number is not enough.As the number of subscriber lines and terminals increases, the number of objects to be identified increases. There is a drawback that it takes 11ml1K to identify the original. Furthermore, if it is inappropriate for you to respond on your own terminal due to identification, for example, if you can tell from the caller number displayed on the display of the telephone terminal that the other party is only for making 7Aku V scolding calls, you can use this. The person who makes the decision must connect the designated 77-phone terminal to the incoming call area and activate it. occurs.

The present invention provides a simple exchange device, such as a private branch exchange center button telephone device installed in a subscriber's premises, which is provided with a number storage means, in which the combination of the subscriber number and the terminal to which the call is to be received is stored in advance. Then, when a call is received, the calling party number transmitted from the network side is compared with the stored subscriber number, and depending on the result, a communication path switch for mutual connection between the subscriber line and the terminal is used. It is also possible to provide a nine-calling device that eliminates the above-mentioned drawbacks and the like by controlling the closing of the telephone, and controlling the visible display of incoming calls and special audible ringing tones as necessary.

FIG. 1 shows an embodiment of the present invention, in which the switching device 2 accommodates at least one subscriber, in the example of a third party, three subscribers, as well as telephones 3 to 5, a facsimile terminal 6, and a simple data A terminal 7 is housed therein, and the subscriber line 1 and terminals 3 to 5 can be interconnected through a communication path switch 8.

In the switching device 20, the circuit that is always connected to the subscriber line IK is the originating subscriber number receiving circuit 10, and the circuit that is always connected to the terminal side communication line is the ring tone 1 line 140 that is always connected to the subscriber line IK.
This is the output side. Each terminal, on the other hand, often has a limited number of calling subscribers who frequently make calls. A combination (pair) of the originating subscriber number and its corresponding terminal O response terminal number is stored in the number storage circuit 11 in advance. The output of the originating subscriber number receiving circuit 1G and the nine subscriber numbers stored in the number storage circuit 11 are compared in the number matching circuit 12, and the comparison output is inputted to the twist control circuit 9. The output of the Hiro terminal Sorabatake viewing circuit 13 is also input to the control circuit 9 . The first output side of the control circuit 9 is connected to the control input side of the communication path switch 80, and the second output side is connected to the input side of the flexible ringer circuit 140 and the input side of the incoming visual display circuit 18. connected to. The output state of the incoming visual display circuit 1s is configured to be input to the incoming visual display 16. The calling subscriber number receiving circuit 1G is also connected to the threat code storage path 11.

FIG. 2 is a flowchart showing the operation when the configuration shown in FIG. 1 receives a paging signal from the switching network.The operation of the first WJ will be explained below in accordance with the flowchart.

When the calling subscriber number receiving circuit 10 detects the arrival of the calling signal in step (a), it immediately starts receiving calling party number information from the switching network. In the next step (b), the calling subscriber number circuit 10 outputs to the number matching circuit 12 whether or not the calling party number information has been received at a certain timing after the calling signal is detected. If calling party number information is not received in step (-), proceed to step 4.0 If calling party number information is received, in step (c), the calling subscriber number receiving circuit 10 switches to the number storage circuit. 11 is activated.The number storage circuit 11 sequentially reads out pairs of previously registered subscriber numbers and response terminal numbers and outputs them to the number verification circuit 12.

The number verification circuit 12 receives the calling party number reception completion signal and the calling party number from the calling subscriber number receiving circuit 10, and compares and checks this with the subscriber number sequentially output from the number storage circuit 11. do. If the comparison operation ends without finding a match in the numbers in this step), step (
Move on to the operation.

If the numbers match in step), step (e)
The matching contents and the corresponding response terminal number are sent from the number matching circuit 12 to the control circuit 9. The control circuit 9 identifies whether the O call is for the stain filling machines 3 to 5 or the call is for terminals 6 and 7 other than telephones based on the O response terminal number. In the pigeonhole step (to) in which the identification result is a telephone call, the control circuit 9 determines whether the telephone specified by the input answering terminal number is idle based on the output of the terminal idle monitoring circuit 13, If it is empty, the special audible ringing circuit 14 is instructed to exit the special audible ringing tone. This ring tone number storage circuit 11 contains a ring tone different from the ring tone used when receiving a call from a caller having an unregistered subscriber number. If the designated Kyuden system is blocked, the call is not called, but the incoming call visual display path 1s is operated to visually display the incoming call on the incoming call visual indicator 16. Next, if the station is called and the Kyuden system responds, the terminal air occlusion monitoring circuit 1 will be activated.
3 detects this, the signal is transmitted to the control circuit 9, and the control circuit 9 connects the call path switch circuit 8 with the subscriber line where the incoming call is received and the call line of the answering telephone. At the same time, the special flexible ring tone circuit 14 is instructed to finish sending out the ring tone. Communication between the originating subscriber and the terminating subscriber starts from the point of time.

If it is identified in step (E) that the call is to a terminal other than a telephone, in step (G) the terminal idle monitoring circuit 13 detects the idleness of the terminal specified by the responding terminal number inputted to the control circuit 9ei. After making a judgment based on the output, if it is empty, the call path switch circuit 8 is instructed to interconnect the subscriber line receiving the call with the call line of the terminal having the answering terminal number. When the mutual connection is made in the communication path switch circuit 8, an O call 1 signal from the switching network side reaches the connected terminal, so that terminal is activated by the O call signal, and in response, an automatic If you press "K" to answer, the incoming call will be answered automatically. Alternatively, incoming call visual display 1 may be indicated by control circuit 90 instruction.
) The recipient may see the called terminal number displayed at 16 and manually activate and respond to the terminal.

If the calling party number information cannot be received in step (cl), the number verification circuit 12 outputs a verification rate-condition O signal to the control circuit 9. Upon receiving this, circuit 9 takes step (9
) to check whether telephones 3 to 41 among telephones 3 to 4 are connected to reception telephones, and if they are empty, instruct call path switch circuit 8 to connect to the reception telephones.

Show. ζO11! In the next step), an O ring signal arrives at the reception telephone from the switching network side, and a call is made. Step (If the reception telephone is occupied by a man, the incoming call is visually displayed on the incoming call visual indicator 16. At this time, when the reception telephone becomes empty, the control circuit 90 controls 0% and the call path switch circuit 8 receives the call. When a call is made to the subscriber, the reception telephone enters the ringing state.Then, when the reception telephone receives a response, the telephone immediately shifts to the talking state.

As mentioned above, the calling subscriber number sent from the network side is received by the switching device on the terminal side, and the terminal
After checking the subscriber number with the subscriber number, it will ring or display an incoming call as necessary while connected to the answering terminal corresponding to that subscriber number, making it easy to identify the terminal that should answer when the call arrives. This eliminates the burden of response operations on the user on the receiving side. Nine, the user on the calling side also has the advantage of being able to call the target terminal directly if the subscriber number of the caller is sent to the other party and the terminal to respond is also specified.

In the above, a plurality of O terminals such as telephones and facsimile terminals are accommodated in the exchange 2, but this invention can also be applied when 1') D terminals are accommodated, and in that case, the registered number corresponds to the subscriber number. The calling subscriber can be identified by the sound of a special ring tone. Furthermore, in the above description, a so-called microcomputer may be used to not only operate the control circuit 9 but also to receive the calling subscriber number, verify the number, and monitor whether the terminal is idle or not. The ζO calling device assumes that the calling subscriber number is sent from the network side, but even if it is configured to send it automatically on the company line side, when there is an incoming call, the calling subscriber number will be sent from the terminal side to the calling side. If the configuration is configured to meet the requirements, it can be applied to current communication networks.
