JPH04170136A - Catchphone call signal informing system - Google Patents

Abstract

PURPOSE:To inform the arrival of a call signal of a catchphone even during the data communication of a facsimile equipment or a data terminal equipment by connecting a call-waiting telephone call signal detector to a subscriber line so as to detect the call signal. CONSTITUTION:Suppose that a changeover switch 31 is thrown to a picture facsimile transmission section 32 and a facsimile equipment 3 is in data communication with a facsimile equipment 4. In this case, when a telephone set makes a call to a telephone set 2, a call-waiting telephone incoming call signal is sent from a general public line network 6 to a subscriber line. When a call- waiting telephone call signal detector 1 detects the arrival of the call-waiting incoming call signal, an LED 11 goes off, a buzzer BZ 12 is energized and the presence of the incoming call is informed to the operator of the telephone set 2. Thus, the operator of the telephone set 2 recognizes the presence of the incoming call by the LED 11 which goes off and the sound of the BZ 12, hooks off a handset of the telephone set 2, the changeover switch 31 selects the line to the position of the telephone set 2 and the talking with the operator of the telephone set 5 is attained by hooking from the telephone set 2.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a call waiting signal notification system.

[Conventional technology]

The conventional call-waiting ring signal notification system sends a call-waiting ring tone from the subscriber's line to the handset of the telephone during the call via the subscriber's line.

[Problem to be solved by the invention]

The conventional call-waiting ring signal notification method described above sends a call-waiting ring tone from the subscriber's line to the handset of the telephone during the call via the subscriber's line. facsimile machines and data terminals that sometimes perform image and data communications have the disadvantage that they cannot hear the signal tone during communication, so they cannot tell when a call comes in.

[Means to solve the problem]

The call waiting ring signal notification system of the present invention connects to a subscriber line to which at least a communication device including a telephone is connected, detects an incoming call signal of a call waiting from the subscriber line, and sends out a visual display and an audible sound. It has a call waiting signal detection device that notifies you of the call waiting signal.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram showing an example of application of an embodiment of the present invention.

In FIG. 1, this application example is a call waiting calling signal detection device 1 connected to a general public line network 6 via a subscriber line.
, a facsimile device (hereinafter referred to as FAX) 3 connected to a general public line network 6 via a call waiting ring signal detection device 1, a FAX 4 connected to the general public line network 6, and a telephone 5. There is.

The call waiting ringing signal detecting device 1 includes a buzzer (BZ) 12 that audibly displays when an incoming call signal of a call waiting from a subscriber line is detected, and an LED II that visually displays the ringing signal.

The FAX 3 includes a changeover switch 31 for switching connection to the telephone 2.

Next, the operation of an application example of this embodiment will be explained.

The changeover switch 31 switches to the image transmission section 32 and the FA
Assume that X3 is performing data communication with FAX4. At this time, when the telephone 5 makes a call to the telephone 2, a call waiting signal is sent from the general public line network 6 to the subscriber's line. When the call waiting ringing signal detection device 1 detects the arrival of the call waiting ringing signal, the LED 1
1 is turned off and BZ 12 is made to ring, notifying the operator of telephone 2 that there is an incoming call.

The operator of telephone 2 must turn off the LED II and turn off the BZ12.
Knowing that there is an incoming call from the sound, pick up the handset of telephone 2, switch the line to telephone 2 using the changeover switch 31, and hook from telephone 2 to telephone 5.
You can talk to the person handling it.

〔Effect of the invention〕

As explained above, the present invention detects a call signal by connecting a call waiting ring signal detection device to a subscriber's line. It has the effect of letting you know.
