[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone terminal that rings or does not ring depending on the ring pattern of a ringing signal coming from a line.

[0002]

2. Description of the Related Art Conventionally, some private branch exchanges have different ringing patterns of ringing signals (bell signals) depending on whether the calling telephone is from an outside line or an extension line. This allowed the responder to obtain only information as to whether it was a call from an outside line or an extension line. Nor was there any control using the ringing pattern. In addition, when a telephone terminal connected to an analog telephone network (hereinafter referred to as a telephone as an example here) receives a ringing signal (bell signal) when receiving a call, the ringing sound of the ringing pattern of the received ringing signal is unchanged. Was being output. Even if the call responder wants to answer only the telephone that he / she has, there is no way to select the calling telephone from the responder. Conventionally, the method of specifying a telephone to ring from the outside line, which is conventionally selected by the calling party, is a dial-in of an additional number method in which an incoming call is answered once and then a PB signal is received, or a telephone network service. There was a method of using a dial-in system, but it required a device such as a PB receiver and was costly.

[0003]

A call signal (bell signal) depends on whether the calling telephone set is from an outside line or an extension line.
In a private branch exchange in which the ringing patterns of No. 2 are different, it has not been performed to control anything by using the ringing patterns. Therefore, all the telephones connected to this private branch exchange always ring regardless of whether they are necessary or not, which is annoying. It is to provide a simple and economical telephone that prioritizes responders.

[0004]

The present invention has the following constitution in order to achieve this object. A ringing signal detector that detects a ringing pattern of a ringing signal coming from a line, a storage unit that stores the ringing pattern of the ringing signal, and a ringing signal that stores the ringing pattern of the ringing signal coming from a line in the storage unit. The telephone terminal in which the ringing portions of only the telephone terminals that are identical to each other are made to operate or not to be operated in comparison with the ringing pattern of.

Reference numeral 40 is a cordless telephone master unit connected to the extension 9 of the private branch exchange, and 50 and 60 are cordless telephone slave units connected to the master unit 40 by a wireless line. 47, 57, 6
7 is a control unit, 48, 58 and 68 are transmitting / receiving units, 52 and 62
Is a storage unit. In the present embodiment, the extension 9 is connected to a private branch exchange (not shown). In addition, those having the same numbers indicate those having the same function.

First, the telephone set 10 is set so as not to ring the telephone call coming from the extension telephone set of the private branch exchange (that is, the incoming call is restricted), and to the telephone calls coming from other telephone lines of the outside line. The operation unit 4 is set in the control unit 7 so as to ring (no incoming call restriction). The private branch exchange can be accessed from an outside line telephone from TEL10
When there is a connection request at 30, the call signal of the normal ringing pattern A shown in FIG. 4 (1) is sent to the extension 9 to which the called telephone is connected. On the other hand, in the telephone 10, as shown in the flow chart of FIG. 5, the ringing signal detection unit 1 detects an output of 16 hertz for the ringing signal of the arriving ringing pattern A, and the detection output of 16 Hz is sent to the control unit 7. To reach.
Then, the control unit 7 compares the ringing pattern stored in the storage unit 2 and determines whether the input ringing pattern is the ringing pattern A or the ringing pattern B. If the ringing pattern is A, the incoming call restriction is not set,
The control unit 7 controls the ring tone generation unit 31 to generate a ringing sound from the speaker 33. If the telephone 10 responds, the telephone of the outside line and the telephone call circuit unit 6 of the telephone 10 are brought into a telephone call state via the extension 9.

Next, when a connection request is made to the TELs 10 to 30 from a telephone of the extension of the private branch exchange (not shown), the private branch exchange sends the ringing signal of the ringing pattern B of FIG. 4B to the extension to which the called telephone 10 is connected. 9 is sent. On the other hand, telephone 1
At 0, as shown in the flowchart of FIG. 5, the ringing signal of the ringing pattern B that has reached is detected by the ringing signal detection unit 1, and the detected output reaches the control unit 7. Then, the control unit 7 determines whether the input ringing pattern is the ringing pattern A,
It is determined whether it is the ringing pattern B. If the ringing pattern B is present, incoming control is set, so the control unit 7
Does not activate the ringing tone generator 31, so no ringing sound is generated from the speaker 33. So phone 1
0 is set to ring when the call is made from the telephone of the outside line, but does not ring when the call is made from the telephone of the extension line. Note that the telephones 20 and 30 (internal circuit is the same as the telephone 10) have neither registration nor incoming call regulation.
The ringing pattern A or B shown in FIG.

Next, the telephone set 20 is made to ring when a call is made from an extension line telephone (that is, the incoming call is not restricted), and the telephone call made from an outside line phone is not ringed (the incoming call is restricted). The operation unit 4 is set in the control unit 7 in advance. When the private branch exchange receives a connection request from an external telephone, it sends a ringing signal of the normal ringing pattern A shown in FIG. 4 to the extension 9 to which the called telephone is connected. On the other hand, in the telephone 20, as shown in the flow chart of FIG. 5, the reached ringing signal of the ringing pattern A is detected by the ringing signal detector 1, and the detected output reaches the controller 7. Then, the control unit 7 determines whether the input ringing pattern is the ringing pattern A or the ringing pattern B. If the ringing pattern is A, the incoming call restriction is set and the control unit 7 does not activate the incoming call sound generating unit 31. Therefore, no ringing sound is generated from the speaker 33.

Next, when there is a connection request from the extension telephone, the private branch exchange sends a ringing signal of ringing pattern B to the called telephone 20.
To the extension 9 to which is connected. On the other hand, in the telephone 20, as shown in the flow chart of FIG. 5, the ringing pattern B that has arrived is detected by the incoming call detection unit 1,
The detection output reaches the control unit 7. Then, the control unit 7 determines whether the input ringing pattern is the ringing pattern A or the ringing pattern B. Now, with the ringing pattern B, the incoming call regulation is not set, so the control unit 7 activates the ringing tone generation unit 31 and causes the speaker 33 to generate the ringing tone. If the telephone 20 responds, the telephone of the extension and the telephone 20 are brought into a call state via the extension 9. Therefore, the telephone set 20 does not ring when the call is made from the extension telephone, but does not ring when the call is made from the outside telephone. Since the telephone set 30 does not have the incoming call restriction set, the telephone 30 rings in the same pattern as the ringing pattern A or B shown in FIG.

In the above embodiment, the telephone having the same function in which a plurality of telephones are connected in parallel to the extension 9 has been described. Next, as shown in FIG. 3, the extension 9 is housed in the cordless telephone master unit 40 and is also cordless. A case will be described in which the ringing pattern of the ringing signal is detected by the ringing signal detection unit 1 and the control unit 7 provided only in the telephone base unit 40. When the private branch exchange receives a connection request from an outside line telephone, it sends a ringing signal of the normal ringing pattern A shown in FIG. 4A to the extension line 9 to which the master unit 40 is connected. On the other hand, base unit 40
Then, as shown in the flow chart of FIG. 5, the ringing signal of the ringing pattern A thus reached is detected by the ringing signal detection unit 1, and the detected output reaches the control unit 7. Then the control unit 7
Is the input ringing pattern A ringing pattern A?
It is determined whether it is the ringing pattern B. Now, since the ringing pattern A is set, the handset 50 for which the incoming call restriction is not set performs the ringing operation as follows. That is, the control unit 7 controls the transmission / reception unit 48 to emit data indicating that a call has occurred as radio waves. In the handset 50, the transmission / reception unit 58 receives this data, the control unit 57 activates the ring tone generation unit 31, the amplification unit 32 performs signal amplification, and the speaker 33 is activated.
The ringing sound is output from. If there is a response from the handset unit 50, the call circuit unit 6 of the handset unit 50 enters a call state with the calling telephone set via the transmitting / receiving unit 58, the base unit 40 and the extension 9. In addition,
Since the slave unit 60 performs the same operation as the slave unit 50, the description thereof will be omitted. On the other hand, when the ringing pattern A is set for the parent device 40, the incoming call restriction is set, so the control unit 47 of the parent device does not activate the ringing tone generation unit 31, and no ringing sound is output.

Next, when there is a connection request from the extension telephone,
The ringing signal of the normal ringing pattern B shown in FIG. 4 (2) is sent to the extension 9 to which the parent device 40 is connected. In the master device 40, as shown in the flow chart of FIG. 5, the ringing signal of the ringing pattern B that has arrived is detected by the ringing signal detection unit 1, and the detected output reaches the control unit 47. Then the control unit 4
7, the input ringing pattern is B, and therefore the slave units 50 and 60 for which incoming call regulation is set are not controlled. On the other hand, in base unit 40, when ringing pattern B is set, incoming call restriction is not set, so control unit 47 of the base unit activates ringing tone generation unit 31 and causes speaker 33 to output a ringing sound.

When the ringing signal is the ringing pattern B, the cordless handset 5
If you want to make a private call that rings only 0, you can do as follows. The controller 47 of the handset 50, which has detected the ringing pattern B, controls the transmitter / receiver 48 to insert the identification data of the handset 50 and emit a radio wave. Handset 50
Is received by the transmission / reception unit, and if the identification data of the user is included in the data, the control unit 57 detects this and activates the ring tone generation unit 31 to generate a ringing sound from the speaker 33. The handset 60 does not ring because it does not include its own identification data in the received data.

In the above description, the ringing pattern of the ringing signal is two types, that is, the outside line and the inside line. However, the ringing pattern of the ringing signal is made different for each extension telephone set, or the ringing signal is set for each extension telephone group. If the ringing pattern of is different, it is possible to perform various controls other than the private call and other ringing operations. For example, when a ringing signal of a certain ringing pattern is received, the telephone can be automatically switched to a facsimile, and the telephone can be automatically switched to a telephone terminal other than the telephone.

Although the call signal coming from the private branch exchange has been described in the above description, it may be the main unit of the key telephone apparatus or the exchange of the central office as long as it produces various ringing patterns.

[0015]

In the telephone of the present invention, when the ringing pattern of the ringing signal coming from the line is different,
By judging the ringing pattern of the received ringing signal, if the caller does not want to answer the call, he / she does not ring his / her own phone and rejects the incoming call. It can be said to ring and respond. If a plurality of telephones are connected to the line, the settings can be changed individually. Further, in order to add the above-mentioned function, it is possible to easily realize it by adding a means for judging a ringing pattern to the telephone terminal, so that it is economically possible.
