DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ISDN terminal having a telephone function and a port function, and more particularly to a method for controlling generation of a ring tone.

[0002]

2. Description of the Related Art In an ISDN, a plurality of channels can be communicated through one interface (line), so that a plurality of different parties can be simultaneously communicated. For example, in the case of a basic interface having two B channels and one D channel, it is possible to simultaneously communicate with two partner terminals. As such ISDN-related terminals, there are terminals having a telephone function and a port function (hereinafter, referred to as ISDN telephones). That is, there is an ISDN telephone which functions as a telephone and functions as a connection between a data processing device (non-telephone terminal) such as a personal computer and an ISDN line, and can simultaneously execute these functions.

FIG. 2 is a block diagram showing a configuration of a conventional ISDN telephone. In FIG. 2, an ISDN telephone is connected to an ISDN line via a line interface unit 10. The driver / receiver unit 20 is an ISDN
The signal from the line is received and processed, and the layer 1/2 control unit 30
And sends out a transmission signal from the layer 1/2 control unit 30 to the ISDN line via the line interface unit 10.

[0004] The layer 1/2 control unit 30 performs layer 1 and layer 2 processing, and provides D-channel information (16 Kbps), which is a signal channel, of the received information to the layer 3 control unit 40. The information (64 Kbps) of two B channels as information channels is provided to the B channel selector unit 80. Layer 1
The / 2 control unit 30 forms a transmission signal (transmission frame) from the D channel information from the layer 3 control unit 40 and the B channel information from the B channel selector unit 80.

[0005] The layer 3 control section 40 executes processing of layer 3 and supplies a control signal from the operation panel section 50 to the layer 1/2 control section 30 as D channel information. The control signal is obtained from the D channel information from the / 2 control unit 30 and is given to the operation panel unit 50. Further, it determines whether the information relates to the telephone function or the port function, and provides a selection control signal to the B channel selector unit 80 based on whether the B1 channel or the B2 channel is used. . Further, it detects an incoming call based on the received D channel information and gives a ring tone generation command to the ring tone generation circuit 60.

The operation panel unit 50 receives an operation input by a user and displays a communication status and the like.

[0007] The ringing tone generation circuit 60 includes a layer 3 control unit 4.
When a generation command is given from 0, a ring tone signal having the tone color and volume set in the volume / tone color switching circuit 140 is generated and sounded by the sounder 70.
Note that the volume / tone switching circuit 140 has, for example, three stages of tone and volume, and provides the tone generation circuit 60 with any tone command and volume command according to the switching setting.

[0008] In the B channel selector section 80, layer 3
When the telephone function is selected based on a selection command from the control unit 40, one of the two B channels connected to the layer 1/2 control unit 30 is switched to the audio codec unit 90.
When the port function is selected, one of the two B channels connected to the layer 1/2 control unit 30 is connected to the speed conversion unit 120.

The speech codec section 90 includes a speech circuit 100
For example, the transmission audio signal given by the communication device 100 is encoded into audio data of 64 Kbps, or the received audio data is decoded and supplied to the communication circuit 100. The communication circuit 100 performs processes such as amplifying an audio signal from the handset 110 and amplifying an audio signal to the handset 110.

This ISDN telephone can be connected to a data processing device such as a personal computer via a DTE interface unit 130, and a speed conversion unit 120
Performs speed conversion for matching the communication speed of the data processing device with the communication speed of the ISDN telephone.

As described above, the ISDN telephone having the above configuration can perform simultaneous communication using two B channels (information channels). That is, communication using the telephone function and communication using the port function can be performed simultaneously. The information processing (data processing) during communication naturally differs between the telephone function and the port function, but the outgoing call processing and the incoming call processing are the same for communication relating to any function except for switching channels. For example, a ring tone is similarly generated at the time of an incoming call related to the telephone function and at the time of an incoming call related to the port function.

[0012]

The above-mentioned conventional ISD
In the case of the N telephone, a ring tone is similarly generated from the sounder 70 regardless of whether it is an incoming call related to the telephone function or an incoming call related to the port function.

However, the conventional ring tone control has the following problems. For example, when an incoming call related to the port function occurs while performing a communication related to the telephone function, a ringtone is generated during the call, which may hinder the call. In order to solve such inconvenience with the conventional configuration, when the communication by the telephone function is started, the operation of setting the volume by the volume / tone switching circuit 140 to the minimum stage may be performed. There is a possibility that the user may not recognize the incoming call related to the next telephone function by forgetting to return the switching to the original stage, and it is complicated to perform the switching operation one by one. Further, even if the ISDN telephone has a telephone function and a port function, there is a possibility that a user who uses only one of the functions may appear, and there are many problems in generating a ringtone for a function that is not used. .

As described above, the conventional configuration has a serious problem in terms of the degree of freedom of the user for the generation of the ringtone.

The present invention has been made in view of the above points, and has as its object to provide an ISDN terminal having a telephone function and a port function in which the user has a high degree of freedom in controlling the tone generation of a ring tone. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an ISDN terminal according to the present invention (hereinafter referred to as an ISDN telephone) will be described in detail with reference to FIG. In FIG. 1, the same or corresponding parts as those in FIG. 2 described above are denoted by the same reference numerals.

As shown in FIG. 1, the ISDN of this embodiment
The telephone has a switching circuit 200 for individual ring tone control and a display unit 300 for individual alert notification in addition to the same configuration as the conventional one.

The ringing tone individual control switching circuit 200 switches the tone control state of the ring tone relating to the telephone function independently of the port function, and switches the tone control state of the ring tone relating to the port function independently of the telephone function. It is for switching.

A telephone function on / off switch 210 and a telephone function display element 220 are provided to control the generation of a ringtone relating to the telephone function. The on / off switch 210 and the display element 220 correspond to the layer 3 control unit 4
It is provided in series between 0 and ground. The on state of the on / off switch 210 means that the generation of a ring tone relating to the telephone function is regulated. When the on state is on, the layer 3 control unit 40 controls the ring tone generation circuit 60 even if there is an incoming call relating to the telephone function. Is not output to the terminal. At this time, the display element 220 is turned on, and informs the user that the on / off switch 210 is on. On the other hand, the off state of the on / off switch 210 means that the sounding of the ring tone relating to the telephone function is not regulated, and the layer 3 control unit 40 determines that the incoming call related to the telephone function has a ring tone when in the off state. A ringing tone generation command is output to the generation circuit 60. At this time, the display element 220 is turned off,
The user is informed that the on / off switch 210 is in the off state.

The switching circuit 200 for individual ring tone control includes a ring tone for controlling the sound generation of the ring tone related to the port function.
A port function on / off switch 230 and a port function display element 240 are provided. The on / off switch 230 and the display element 240 are also provided in the layer 3 control unit 40.
And grounded in series. The on state of the on / off switch 230 means that the generation of the ring tone related to the port function is regulated. When the on state is on, the layer 3 control unit 40 controls the ring tone generation circuit 60 even if there is an incoming call related to the port function. Is not output to the terminal. At this time, the display element 240 is turned on, and informs the user that the on / off switch 230 is on. On the other hand, the on / off switch 230
The off state means that the sounding of the ring tone related to the port function is not regulated, and when the state is off, the layer 3 control unit 40 A sound generation command is output. At this time, the display element 240 is turned off and the user is informed that the on / off switch 230 is off.

The display unit 300 for individual notification of incoming call is composed of two display elements 310 and 320, and the layer 3 control unit 40
It is connected to the. The display element 310 is turned on by the layer 3 control unit 40 when an incoming call related to the telephone function occurs. The display element 320 is turned on by the layer 3 control unit 40 at the time of an incoming call related to the port function.

The above-described operation panel section 50 has a display section, and displays a message indicating an incoming call at the time of an incoming call. For example, if there is an incoming call related to the port function during communication by the telephone function, the operation related to the port function is performed. Only the incoming call is displayed. Conversely, if there is an incoming call related to the telephone function during communication by the port function, only the incoming call related to the telephone function is displayed, and it is not possible to display whether or not both are communicating. As described above, when the ring tone can be regulated for the telephone function and the port function, the user cannot recognize the incoming call and the communication being performed by the ring tone.
0 and 320 are provided.

In the above arrangement, for example, the user turns on the port function on / off switch 230 before making a call for a call related to the telephone function or when starting a call due to an incoming call related to the telephone function. At this time,
The port function display element 240 is turned on to notify that it is in the on state. In such a call state, if there is an incoming call related to the port function from the outside to the ISDN telephone, the layer 3 control unit 40 detects the incoming call. The layer 3 control unit 40 includes the port function on / off switch 2
Since the switch 30 is in the ON state, no ring tone generation command is output to the ring tone generation circuit 60 regardless of the incoming call. In this way, it is possible to regulate the sounding of a ringtone for an incoming call related to the port function during a call related to the telephone function. By turning on the display element 320, the user can recognize an incoming call related to the port function.

For example, when using the ISDN telephone only with the port function, the user turns on the telephone function on / off switch 210. At this time,
The telephone function display element 220 lights up to notify that it is in the ON state. In such a state, when there is an incoming call related to the telephone function to the ISDN telephone from outside, the layer 3 control unit 40 detects the incoming call. Since the telephone function ON / OFF switch 210 is in the ON state, the layer 3 control unit 40 does not output a ring tone generation command to the ring tone generation circuit 60 despite the incoming call. In this way, it is possible to regulate the sound of a ring tone for an incoming call relating to an incorrect telephone function to the ISDN telephone. By turning on the display element 310, the user can recognize an incoming call related to the telephone function.

In the above, two usages of the switching circuit for individual ring tone control 200 by the user have been described. However, the usage of the switching circuit for individual ring tone control 200 is left to the user and can be used in any manner. be able to.

Therefore, according to the above-described embodiment, the ringing tone individual control switching circuit 200 is provided to determine whether or not a ringing tone is generated when an incoming call related to the telephone function is made. Since the user can individually set whether or not to generate a ring tone, it is possible to realize an ISDN telephone having a high degree of freedom relating to ringtone control.

In this way, the display elements 220 and 2 for visually confirming the setting state of the switching circuit 200 for individual ring tone control.
By providing 40, the user can easily confirm the individual control state of the ringtone.

Even if a ring tone is not generated, the incoming call can be confirmed by the display elements 310 and 320 if necessary, and there is no problem with the regulation of sound generation.

In the above-described embodiment, both the telephone function and the port function can individually control the ring tone. However, in practice, the biggest reason for restricting the ring tone is that the port number in the call state is the largest. Since it is a ringtone relating to a function, it is sufficient if at least a configuration for restricting a ringtone relating to a port function is provided.

In the above embodiment, the ISDN
Although the present invention is applied to a telephone, it can be applied to other ISDN terminals such as a so-called video telephone and a facsimile apparatus using an ISDN line. In short, the present invention can be applied to an ISDN terminal having a telephone function and a port function.

Further, in the above-described embodiment, the individual control of whether or not the ring tone is generated is described. However, the volume of the ring tone may be individually controlled. In this case, it is necessary to provide a control signal from the layer 3 control unit 40 to the volume / tone switching circuit 140 as well.

[0039]

As described above, according to the present invention, at least the port function is provided for the corresponding function.
Set the volume of the ringtone for notifying the incoming call according to the instruction of the terminal user.
A ring tone switching means for setting a call function according to a port function generated during the communication of the telephone function.
When a call is detected, a ring tone generation command corresponding to the setting of the ring tone switching means is given to the ring tone generating means, so that the user can have more flexibility in controlling the sound generation of the ring tone than before.
