Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a special line aggregate reception stand suitable for use as a telephone for exclusive use of multi-line incoming calls such as reception of an emergency call special line.

[0002]

2. Description of the Related Art Emergency call special line reception (generally 5 to 5) that does not have a general command center of a wide area municipal area maintenance association (wide area fire department) in a local small and medium-sized city that has been operated as a conventional emergency call reception device. 10 lines) have the following problems.

(1) Telephone line for each direction (for example, PFT)
An old black telephone is installed for each (via a special line trunk such as a police fire trunk), and a reverse switch (control signal for a special line) required for reception is also used as a device for transmitting a changeover switch such as A Tenkanki. It took up space such as installing each one, and it was inefficient and aesthetically problematic.

(2) Since a modified business phone is used and a power source is used, it is necessary to install a spare battery, and at the same time, the most important factor is the one seen at the time of the previous Hokkaido-Oki earthquake. There was concern that there would be a delay in responding to calls from all directions, as only the number of telephones (usually 2 to 3) could be received.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is compact and lightweight, does not require a power source, and allows a plurality of special lines to be integrated into a single reception board, and the special lines can be easily provided. It is an object of the present invention to provide a special line aggregate reception board having a control signal transmission function.

[0006]

In order to achieve the above object, the special line aggregate reception board of the present invention is a device that accommodates a plurality of special lines and is capable of answering an incoming call and making a call. A special line reception circuit that includes an incoming call display circuit that displays an incoming call from the special line, a signal transmission circuit that sends out a control signal for the special line, and a telephone circuit that has a function of talking to the incoming call and disconnecting the line. It is characterized by accommodating multiple special lines in a one-to-one correspondence and storing them in a single housing. It is compact and lightweight and does not require a power supply. It is capable of transmitting a special line control signal easily.

[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a structural explanatory view showing an embodiment of the present invention. In the figure, reference numeral 1 denotes a set reception board for special lines, which accommodates 10 special lines L00 to L09. 100-1
Reference numeral 09 is an incoming call display circuit for displaying an incoming call from the special line L00 to L09, 200 to 209 is a telephone circuit having a function of talking with the incoming call and disconnecting the line, and 300 to 309 is a signal for sending a signal for controlling the special line. The sending circuit, E, is ground.

FIG. 2 is a specific circuit diagram of FIG. 1. The special lines L00 to L09 are composed of lines L1 and L2, respectively, and the lines L1 and L2 are respectively connected to the modular jacks MJ00 to MJ90. . Each of the modular jacks MJ00 to MJ90 corresponds to the telephone TE through the connectors of the telephone circuits 200 to 209.
It is connected to L0 to TEL9. Between the modular jacks MJ00 to MJ90, there are correspondingly corresponding incoming indicator lights REC0 to REC9 such as neon lamps and resistors R.
Incoming call display circuit 100 to which R00 to R90 are connected in series
109 is connected. Each modular jack MJ0
0 to MJ90 correspond respectively to the reverse signal transmission key RC0
It is connected to the case earth E through RC9. The reverse signal transmission keys RC0 to RC9 form signal transmission circuits 300 to 309, respectively.

FIG. 3 is an explanatory diagram showing an example of a relay system according to the present invention, which is a special line L00 consisting of 10 lines.
The reception co-operated telephones TEL0 to TEL9 of L09 are integrated into one set reception table 1.

4 and 5 show an embodiment of the present invention,
4 is a perspective view, FIG. 5 (a) is a plan view, FIG. 5 (b) is a front view, FIG. 5 (c) is a rear view, and FIG. 5 (d) is a side view.
In the figure, S0 to S9 are auxiliary switches for additional functions.
That is, ten compact telephones TEL0 to TEL9 are installed in parallel on the set reception table 1 of the iron plate assembly. Each of the telephones TEL0 to TEL9 is installed on the set reception desk 1.
Corresponding to the respective incoming call indicators REC0 to REC9, reverse signal sending keys RC0 to RC9 and spare switches S0 to S
9 is added as an external equipment. In one housing of the set reception board 1, the incoming call display circuits 100 to 109, the signal transmission circuits 300 to 309, and the telephone circuits 200 to 209.
The reception circuits for the special lines L00 to L09 are collectively housed in a plurality of special lines L00 to L09 in a one-to-one correspondence. The device dimensions are, for example, width 900 mm, depth 30
It is compact and lightweight with a height of 0 mm and a height of 190 mm, does not require a commercial power supply or battery, and can be used even during a power failure.

That is, when a call is made to the telephones TEL0 to TEL9 arranged in parallel via the special lines L00 to L09,
At the same time that the ringing signal rings for each line by the calling signal, the incoming call indicators REC0 to REC9 blink, so that the calling direction can be identified immediately. By turning on the reverse signal transmission keys RC0 to RC9, the control signals for the special lines L00 to L09 can be transmitted for each line, and the telephones TEL0 to TEL9 can respond to the incoming call and talk.

According to this embodiment, there are the following effects.

(1) This device (for 10 lines) can be applied to a plurality of emergency call special lines, and a special line reception device with a reverse signal transmission function simply by connecting the first type earth to the ground terminal. Can be used as

(2) This device is small and lightweight and can be easily carried to any place. It does not require a power source and is not affected by lightning damage or power failure, so it can be used in emergency situations such as temporary disaster response headquarters. If you have a telephone line, you can use up to 10 lines. (It can be used as a semi-command board simply by placing it on an ordinary office desk.) (3) This device is compact and lightweight, does not require a commercial power source, and can be easily installed anywhere on the desk as long as a telephone line can be secured. Up to 10 lines can be used as an emergency call reception device.

(4) If this device is used as a backup telephone for a special line, which is accommodated in a command board (including a general command board) that uses the current power source, it can be stored compactly without taking up space.

(5) If this device is used as a telephone for exclusive use of multi-line incoming calls, it can be used for occasional events or events in which inquiries are inundated at one time.

(6) The calling status of the telephones arranged in parallel in this apparatus can be recognized by the blinking (calling signal) of the neon lamp installed for each telephone, and the reverse signal transmission function switch and the auxiliary switch of the additional function are provided.

[0019]

As described above, according to the present invention, it is possible to combine a plurality of special lines into a single reception board without the need for a power source, which is small and lightweight, and is equipped with a special line control signal transmission function. It is possible to provide a group reception desk for special lines.
