JPS61181242A - Method for displaying holding state of telephone set - Google Patents

Abstract

PURPOSE:To make the distinguishment between a holding line and an incoming line easy and to decrease current consumption by using a voice signal such as a holding tone to display that a line is in holding. CONSTITUTION:When a switch 6 of an operating section exposed to a telephone set main body 1 is depressed, a holding request signal is sent to the holding circuit 4. Thus, the holding circuit 4 separates a telephone line 3 and a handset 2 and sends a signal tone or melody decided as the holding tone to the talking party and a receiver 7 of the handset 2. Thus, the holding line and the incoming line are distinguished easily and the power consumption is less than that of visual display such as a lamp.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for displaying when a telephone is on hold, and more particularly to a method for displaying when a line is on hold in a cordless telephone system.

(Prior art) Conventionally, as a display method when on hold in a key telephone that shares all of multiple lines, two methods were used: to send all signals such as hold tone to the telephone line on hold, and to provide a voice service indicating that the communication is on hold only to the other party. At the same time, it was common to turn on a lamp attached to the button switch of the telephone, or to flash it at a predetermined cycle to indicate that the telephone line was on hold.

However, in this conventional method, there was no voice service for the party who put the telephone on hold or for other telephones that shared the central office line with the party who placed the telephone on hold. In many cases, the visual display such as ``blink'' flashes at a different frequency from when the call is on hold.Therefore, if the line on hold and when the call is received are visually displayed at the same time, the difference in the cycle of 1 blink will tell the difference between 1 incoming call and 1 call on hold. The drawback was that it was extremely difficult to distinguish between them.

In addition, for cordless phones that use batteries as a power source for internal circuits, visible indicators such as lamps when on hold will speed up battery consumption, requiring the user to replace the batteries more frequently. It has the disadvantage that it should not be used.
There was a problem in that the conventional method as described above could not be suddenly adopted.

(Object of the Invention) The present invention has been made in order to eliminate the above-mentioned defects in the display method of on hold in conventional telephones, and it is easy to distinguish between the held line and the incoming line, and the current consumption is reduced. The overall purpose of this invention is to provide a method for indicating that a line is on hold, which is suitable for devices that use batteries, such as cordless telephones.

(Structure of the Invention) In order to achieve this object, the present invention provides an audio signal such as a hold tone to notify the handset of a telephone on hold and other telephones sharing a line with the telephone that the line is on hold. Configure it to display by sending all.

(Embodiments of the Invention) The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 1 (al) is a block diagram showing an embodiment of a telephone to which the present invention is applied.

In the figure, 1 is a telephone main body, and 2 is a handset connected thereto.The telephone main body 1 is connected to the outside through a telephone line 3, and inside the main body 1 is a hold circuit added in the present invention. 4, the telephone line 5 is connected to the telephone line 3, and the holding circuit 4 is connected to the telephone main body 1.
A switch 6 with its operation part exposed is connected to the surface of the receiver, and the hold tone output is connected to the handset 7 of the handset 2 described above.

On the other hand, the handset 2 is equipped with a transmitter 8 in addition to the above-mentioned receiver 7, and these transmitters 7 and 8 are connected to the communication circuit 5 of the telephone body 1, respectively.

By operating the switch 6 attached to the hold circuit 4, the telephone line 3 and the handset 2 are separated, and a signal designated as a hold tone is sent to the other party and the handset 7 of the handset 2. It sends out sounds or melodies.

With this configuration, a voice hold indication can also be given to the handset connected to the telephone that has put the line on hold.

Not only the operator who placed the telephone on hold, but also other persons holding the telephone can easily identify that the telephone is on hold.

FIG. 1 (b+ is a block diagram showing an embodiment of a cordless telephone to which the present invention is applied. This shows a master telephone 9 connected to a telephone line 3 and one or more slave telephones 10 connected to this by a wireless line. and constitute a cordless telephone device.

The master telephone 9 is connected to the holding circuit 4 shown in FIG. 1 (at).
In addition to the communication circuit 5, a receiver 11 and a transmitter 12 are built in, and radio waves are transmitted and received via antennas 13 and 14, respectively.

On the other hand, the slave telephone 10 includes a transmitter 15 and a receiver 16 corresponding to the transmitter/receiver of the master telephone 9, and a communication circuit 17 connecting these. Further, a telephone receiver 7 connected to the communication circuit 17. Transmitter 8. It consists of a switch 18 and antennas 19 and 20 connected to each of the transceivers.

It goes without saying that the slave telephone 10 should have a built-in battery 21 as a power source.

When using the cordless telephone device configured in this manner to place a line on hold, a hold request number is sent out and transmitted to the master telephone 9 by operating a switch 18 attached to the slave telephone 10, etc. The holding circuit built in the section operates to separate the telephone line 3 and the telephone call circuit 5, and transmits data to the other party via the telephone line 3, and to the slave telephone 1'llO. The machine 12 transmits a hold tone or a predetermined melody, respectively, via a wireless line.

On the other hand, the slave phone 10 that has received this holding tone transmits the audio output from the built-in receiver 16 to the handset 7 via the communication circuit 17.
Send to.

To release the hold, the hold switch 18 is operated again to send a hold release signal to the master telephone 9.

In this way, the present invention can also be applied to cordless telephone devices.

Since the original operation and functions of the cordless telephone device are self-evident, a complete explanation thereof will be omitted.

(Effects of the Invention) Since the present invention is configured and functions as described above, it is possible to audibly notify the user of the hold state of the telephone line by a signal such as a hold tone on the handset, which is different from the conventional method. It is much easier to recognize than a lamp display, and in cordless phones, it consumes much less power than a lamp or other visible display, which is extremely effective in extending battery life. .
