Abstract

PURPOSE:To indentify the elapse of holding time stepwise through visual display and audible means by visually displaying the lapse of holding time and warning by audible means. CONSTITUTION:In case line wire is set in a holding state, a main control part 14 receives a holding signal, and controls a holding control part 15. The holding control part 15 stores, in the memory area for the corresponding line wire of a holding information memory 17 in a memory 16, the state of holding, the holding time, and the information of holding constituted by the number of the push-button telephone set being held. The part 15 also controls a timer 18 to count the holding time as fat as the holding state lasts, and rewrites the holding time in the holding information memory 17 at every constant period. The rewritten information is checked by the holding control part 15. Every time when the said counting exceeds respective grades of holding time, holding- warning sound and the display correspounding to the exceeded grade are selected, and the signals of them are transmitted to a corresponding push-button telephone set 201 through a push-button telephone interface 12. In the telephone set 201, the warning and the display are executed by a holding-warning source and a displayer.

Description

[Detailed Description of the Invention] [Industrial Application Field] The key telephone device of the present invention includes an outside line interface that accommodates a plurality of outside lines, a button telephone interface that accommodates a plurality of button telephones, and an outside line and a button telephone. It is composed of a main device consisting of a communication path switch that connects the main controller, a memory, and a main controller that controls each of the above-mentioned parts, a button telephone that is equipped with a display, and a hold alarm sound source. is equipped with a function to place an outside line or other key telephone on hold in response to an instruction from an outside line or a key telephone that is in use, and to re-answer the held outside line or key telephone from any key telephone within the device. The present invention relates to a button telephone device.

[Prior Art] Conventionally, in this type of key telephone device, the hold alarm sound is generated by a single sound source with an audible display after a certain period of time, and the alarm state of the elapsed hold time does not change after the certain period of time.

[Problems to be Solved by the Invention] The conventional button telephone device described above returns a visual display of a hold warning and a sound of a hold alarm when the hold time exceeds a certain time, but after a certain time, the hold time elapses. Since there is no means to notify the user of the call, there is a drawback that it is not possible to identify the length of the hold time of the other party.

[Means for Solving the Problems] The button telephone device of the present invention includes a plurality of hold alarm sound sources that emit different hold alarm sounds, and the main control unit:
When the hold button of any button telephone during a call to an outside line is pressed, means for storing hold information of the outside line in the navigation memory, and based on the hold information and elapsed hold time stored in the memory, the hold button is pressed. means for selecting a step-by-step display to be displayed on a display of the telephone and an alarm sound to be generated by the pending source, and transmitting data of the selected display and alarm sound to the button telephone via a button telephone interface; It is characterized by including.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the button telephone device of the present invention.

The main device IO has an outside line interface 11 accommodating outside lines 1, 2, . . . , n, and key telephones 201.20, .
..., button telephone interface 1 accommodating 20n
2, outside lines 1 to n, and key telephones 201 to 20n or key telephone 20. ~20, includes a call path switch 13 that connects mutual calls, a memory 16 including a hold information memory 17, and a hold control unit 15 that controls hold based on the information in this hold information memory 17, and controls each part in the main device. It is composed of a main control section 14 that controls the main control section 14.

Figure 2 shows a button telephone 20. ~20n20n front view.

Each button telephone 20. ~20n is the hold button 21 and 3
It has a hold alarm sound source 22 having two hold alarm sounds, a display 23, and a speaker 24.

Next, the operation of this embodiment will be explained.

Key telephone during outside call 20. hold button 2
When 1 is pressed and the outside line is put on hold, the main control unit 14

be in a pending state in the memory area of the corresponding external line;
Stores hold information consisting of the hold time and the number of the key telephone that placed the hold. While in the hold state, the timer 18 counts the hold time, and updates the hold time in the hold information memory 17 at regular intervals. The rewritten information is checked by the hold control unit 15, and when the hold time of each stage is exceeded, the hold control unit 15 selects the corresponding hold alarm γt and display, and transmits the selected sound source and display data to the button telephone. Through the interface 12, the corresponding button telephone 20. send to Button telephone 20. The hold alarm sound source 22 and display 23 issue an alarm and display. At this time, the timer 18 continues counting the holding time. The main control unit 14 then controls the button telephone 20. When a signal is received to re-answer the outside line that was on hold, the hold information memory 1
From the hold information in step 7, the outside call that was on hold and the key telephone that held hold are determined. The communication path switch 13 is controlled so that the line is placed into a talking state again, and the hold information corresponding to the outside line in the hold information memory 17 is erased.

[Effects of the Invention] As explained above, the present invention provides a visual display and an audible alarm for the elapse of the holding time using a display and several types of hold alarm sounds when an outside call is on hold, thereby making it easier for the party who placed the call on hold to place the call on hold. The elapsed time can be identified step by step with visible and audible display.
This has the effect of warning the other party of being placed on hold for a long time.
