Abstract

PURPOSE:To easily decide a holding passage time by changing an informing sound for alarming the holding of a line wire in stages in accordance with the passage of time at the time of holding the line wire. CONSTITUTION:A holding state deciding and commanding part 16 allows a timer to count up the holding time during the holding state, updates the holding time of a memory 18 every fixed period, and when the holding time exceeds a previously set holding time in each stage, specifies the volume of a holding alarm sound source 22 and a visual display. The volume data of the sound source 22 and visual display data are sent to a corresponding key telephone set through an telephone interface 13 to control visual and audible display. The volume data of the sound source 22 are sent to a holding alarm sound source control part 23 in the key telephone set to control the volume in stages.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a button telephone device, and more particularly to a button telephone device having a call hold function and a hold warning function.

In this type of conventional key telephone device, in response to a call being put on hold, an audible sound is emitted after a predetermined period of time has elapsed in response to a call being put on hold, thereby issuing a hold warning and prompting the user to answer the call. In such conventional key telephone devices, when the hold time exceeds a certain predetermined time, an audible (or visible) warning that the phone is on hold is displayed; There is no means for generating a warning regarding the passage of time. Therefore, there is a drawback that it is not possible to identify the length of the hold time of the other party.

OBJECTS OF THE INVENTION An object of the present invention is to provide a key telephone device that can prompt a call response early by periodically generating a hold warning.

Structure of the Invention According to the present invention, there is provided a button telephone device having a notification means for generating a hold warning after a predetermined period of time has elapsed in response to a call hold operation, wherein the notification means is configured to issue a hold warning in stages as the hold time elapses. A button telephone device is obtained, characterized in that it is configured to generate a hold alert.

Example Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, and FIG. 2 is an external front view of the button telephone main body in the block of the embodiment of FIG. Referring to these figures, each of the button telephones 1 to n has a hold button 21 . Hold warning sound source 22
．． Hold warning sound source control section 231 display 24. speaker 25
Contains.

Note that 20 indicates a handset.

The main unit 11 of the button telephone device is capable of accommodating the above-described button telephones 1 to n having the structure shown in FIG. For this purpose, it has an outside line interface part 12 and a key telephone interface part 13, and further includes a call path switch 14 for enabling not only mutual calls between the outside line and the key telephones, but also mutual calls between the key telephones. It includes a memory 17 and a main control section 15 for controlling these various sections.

The memory 17 is provided with a hold information memory unit 18, and this memory unit 18 stores data such as the call hold time 9 of the outside line and the extension number on which the call was put on hold, corresponding to each of the outside lines 1 to 1 m. Stored. The main control unit 15 is also provided with a hold status determination command unit 16, which has a function of determining the hold status based on the data stored in the hold information memory unit 18.

When the pushbutton telephone i (i=1 to n), which is in the middle of an outside line call, receives an operation to press the hold button 21, the outside line in the middle of the call is placed on hold. In response, the main control unit 15 receives the hold signal and holds the hold status determination command unit 1.
Control 6. This hold status determination command unit 16 is a memory 1
In the memory area corresponding to the corresponding outside line of the hold information memory section 18 in 7, hold data consisting of the fact that the telephone is on hold, the hold time, and the number of the key telephone set on hold is stored. During the hold state, a hold time timer (not shown) is counted to update the hold time in the memory 18 at regular intervals, and the updated data is checked by the hold status determination command unit 16 and set in advance. When the hold time for each stage is exceeded, the hold status determination command unit 16 issues a corresponding hold warning sound (I!). Specify the volume and visual display of 22. The volume data and visual display data of the same sound 11Ft22 are sent to the corresponding button telephone i through the telephone interface 13, and the visual and audible display is controlled. The volume data of the hold warning sound source 22 is sent to the hold warning sound source control section 23 in the key telephone, and the control section 23 controls the volume of the sound source 22 in stages based on the volume data.

During this time, the hold time timer continues to count. When the main control unit 15 receives a signal for re-answering the held outside line from the key telephone, in response, the main control unit 15 receives a signal for re-answering the held outside line from the hold data in the hold information memory unit 18. The call path switch 14 is controlled so that the put-on hold button telephone set is again in a call state. Thereafter, the pending data corresponding to that outside line in the pending information memory 18 will be erased.

By doing this, a warning is generated periodically during the elapsed time of the hold state, and in particular, in the case of a warning sound, the volume is increased as the time increases, so that the outside call that is on hold can be canceled early. This will prompt the user to return to the talking state.

Effects of the Invention As described above, according to the present invention, when an outside line is on hold, a hold warning notice is made in stages as time passes, so the party who put the call on hold can easily keep track of the elapsed time of the call. This has the effect of not making the other party wait for a long time.
