Abstract

PURPOSE:To quickly and surely start a terminal equipment by starting the terminal equipment at a frequency higher than a telephone set call signal frequency and lower than the lower limit frequency of the telephone set voice frequency band. CONSTITUTION:A terminal equipment means 23 starts a facsimile equipment 7 at a frequency 16Hz higher than a telephone set call signal frequency and lower than the lower limit frequency 300Hz of the telephone set voice frequency band and consists of an oscillation circuit such as a multivibrator in an equipment where a terminal equipment call signal coming from a subscriber telephone set circuit is detected and said circuit is switched from a telephone set into a terminal equipment to start it. Thus, a terminal equipment such as a facsimile equipment is started quickly and surely, and in this case malfunction of the terminal equipment due to the telephone set call signal frequency and the telephone set voice frequency is avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a terminal activation device for detecting a terminal device calling signal arriving from a subscriber telephone line and switching the line from the telephone to the terminal device and activating the line.

[Prior art]

In recent years, various terminal devices such as facsimile machines have been attached to subscriber telephone lines.

For example, a known facsimile IJ device is activated by a telephone ring signal consisting of a repeated signal of a 16 Hz AC signal for 1 second and a DC negative voltage for 2 seconds. However, since this conventional device counts the total number of pulses, there is a problem in that startup of the facsimile device is delayed.

〔the purpose〕

The present invention has been made in view of the above-mentioned problems of the conventional device and has been made to solve the problems, and an object of the present invention is to provide a terminal activation device that can quickly and reliably activate a terminal device such as a facsimile machine. .

〔composition〕

The present invention provides a device for detecting a terminal equipment ringing signal arriving from a subscriber telephone line, switching the line from a telephone to a terminal equipment, and activating the same. The configuration includes means for activating the terminal device using a frequency lower than the lower limit frequency.

〔Example〕

Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

First, the overall configuration will be explained with reference to FIG. 1. Reference numeral 1 denotes a terminal call control device, and the lower part of the device 1 is provided with three pushbutton switches 2, 3.4. 3.4 has the function of selecting a mode when the user is at home (at the office) or away by operating a switch. Reference numeral 5 denotes an openable/closable cover member provided at the lower part of the device 1. When the cover member 5 is opened, a push button switch for recording means for recording a telephone answering message is installed inside the cover member (as shown in the diagram). ) is provided. 6 is a telephone, 7 is a facsimile device as a terminal device, and 8.9 is a connection cord for connecting the telephone 6 and facsimile device 7 to the terminal call control device 1. In addition, 10 is a visual indicator for hearing-impaired people, and lamps 11 and 12
The operation procedure of the facsimile machine 7 is displayed by blinking.

Next, the configuration of the control circuit section of the terminal call control device 1 will be explained with reference to FIG. The telephone 6 is connected to the relay contact 14.
A facsimile device 7 is connected to the meter contact side. 15 is the incoming call from the telephone line, L, (16Hz
), 16 is a facsimile ringing signal (1100Hz CNG signal, 13
00Hz silent ring signal), 17 is a ring tone sending means for selecting a telephone ring tone for the calling party, and 18 is a loop for detecting a response when the telephone 6 responds. Detection means; 19, voice response signal sending means comprising a voice synthesis IC for sending a pre-recorded response message from the called side to the calling side; 20, recording means for recording the message from the calling side. , 21 is the telephone line, , L is the telephone 6 or facsimile IJ.
control means for performing various controls such as switching connection to the device 7;
22 is a ringing means for ringing a bell to prompt the telephone 6 to respond, and 23 is a terminal activation means according to the present invention, which has a frequency higher than the frequency of the telephone ringing signal (16Hz) and the lower limit frequency of the telephone voice frequency band. (300Hz).

The facsimile machine 7 is activated by the facsimile machine 7, and can be constructed from an oscillation circuit such as a multivibrator.

In this example, 25Hz is turned ON for 1.4 seconds, 1.4
Adopts a repeating signal with OFF seconds, total number of pulses is 3.
Test results using a 0-pulse facsimile device showed that compared to a conventional device using a telephone ringing signal (16Hz),
It has been confirmed that the device in this example has a quick start-up time and starts up reliably without any malfunction.Next, the operation of this example will be explained. When the pushbutton switch 2 of the terminal call control device 1 is pressed to set the first mode selection function, that is, the at-home mode, the telephone line is %L.

When there is an incoming call, the incoming call detection means 15 detects this, and its output is applied to the control means 21 to form a DC loop, and the control means 21 drives the ringing means 22 to cause the telephone 6 to respond. Ring a bell to prompt. In this way, the bell rings for a predetermined period of time (appropriate number of times), and if the called party takes the handset of the telephone 6 off-hook during this period, this is detected by the loop detection means 18, and its output is applied to the control means 21. The control means 21 issues a command signal based on the detection output of the loop detection means 18,
Since the relay contact 13 operates to switch the contact, if the calling party is making a telephone call, a conversation will be made with the called party. On the other hand, if the calling party is a facsimile device, a facsimile ringing signal is received, this ringing signal is detected by the ringing signal detection means 16, the output thereof is applied to the control means 21, and the called party listens to this ringing signal. Shit no 1
When the handset is turned on-hook, the relay contact 14 is operated based on a command from the control means 21 and the contact is automatically switched to the facsimile machine 7 side, and furthermore, the facsimile machine 7 is started by a start command from the terminal start means 23. It is. After that, the called party identification signal (2100
HzCED signal) to the calling party, and a known protocol based on the recommendations of the Consultative Committee on International Telegraph and Telephone (CCITT) is executed to receive the message. Note that the pushbutton switch 3.4 of the terminal call control device 1 is used to set the mode selection function when the user is away, etc., and when the calling party is a facsimile machine, the relay contact 13.14 is activated. The telephone line L is automatically switched to the facsimile machine 7 side, and the terminal activation means 2
Although the facsimile machine 7 is activated by the activation command from the facsimile apparatus 3 in the same manner as in the above embodiment, a detailed explanation thereof will be omitted.

〔effect〕

As is clear from the detailed description above, the present invention can quickly and reliably start up terminal equipment such as facsimile machines, and at that time, it is possible to prevent the terminal equipment from malfunctioning due to the telephone ringing signal frequency and the telephone voice frequency. This can be extremely effective when using this type of terminal equipment, which is increasing in number.
