[Detailed Description of the Invention] (Field of Industrial Application) The invention is directed to a message transfer method in an automatic switchboard, particularly in an automatic switchboard that displays a predetermined message on the display of a specific terminal in response to a dial signal during a call. Concerning message transfer method.

(Prior Art) Conventionally, hotels and the like have installed telephones connected to private branch exchanges in guest rooms for various services.

Additionally, information on how to dial the phone and main phone numbers is attached as a guide for ease of use. However, when a foreigner who does not speak the language well calls the front desk or restaurant, it can be inconvenient as the request may not be understood in the first place.

There are some cases in which telephone numbers are set up for each call incident to help understand the contents of the communication, but there are limits to setting up telephone numbers for each requirement, and it still does not solve the inconvenience.

(Object of the Invention) The object of the present invention is to eliminate the above-mentioned drawbacks, and to make the dial signal sent during a call correspond to a message, and to provide a signal converter that selects a code string representing a message from the dialed digits. To provide a message transfer system in an automatic converter capable of displaying a message on a display provided on a specific terminal of the other party.

(Structure of the Invention) The message transfer method in the automatic exchange of the present invention is based on a specific terminal means having a display attached to a telephone set, and a dial signal corresponding to a message determined during a call with the specific terminal means. telephone means capable of transmitting a message, signal receiving means for receiving said dial signal arriving during a call, signal converting means for selecting a code string representing a message corresponding to said dial signal arriving during said call, and said signal converting means. and a connecting means for connecting the means and the display of the specific terminal means.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, in which the exchange is an electronic exchange, and the push-button dial telephone (hereinafter referred to as FB telephone) IO has a line circuit 3 having a PB signal receiver.
0 to the communication path switch 50, and the specific terminal 2
0 is PB phone f! The telephone 21 is connected to a line circuit 30 having the same structure as the line circuit 30, and the display 22 is directly connected to a communication path switch 50. Furthermore, the signal conversion device 40
is also connected to the communication path switch 50. Also, the line circuits 30, 31. The communication path switch 50 and the signal converter 40 are connected to a central processing unit 60 via a bus. In addition, in FIG. 1, multiple PBfi
A plurality of specific terminals 20 and a plurality of signal conversion devices 40 are each shown one by one.

The display 22 of the specific terminal 20 is supplied with a stain source by turning off the PB telephone 21, and when it receives a display code, it stores this code and drives the display through a character generator. In addition, new codes are accumulated until there is no gold or white on the display surface, and the oldest codes are erased in sequence. All accumulated codes are erased on hook.

In addition to monitoring the startup and recovery of the terminal, the line circuits 30 and 31 also monitor the startup and recovery of the terminal.
The FB signal receiver receives the connection information (#) and transfers it to the central processing unit 60, but the P.
The B-times signal is received and this numerical information is transferred to the central processing unit 60.

When the digit number conversion device 40 receives numeric information from the central processing unit 60, it sends out one of the code strings representing a plurality of messages stored in correspondence with the digits. Therefore, according to the present invention, the PBfi phone After dialing from the PB telephone 10 and connecting to the specific terminal 20 via the call path switch 50, if you operate the push button of the PB telephone 10 according to the comparison table of dialed numbers and predetermined messages, this The PB multiplication signal line circuit 30 receives the number, and the number is given to the central processing unit 60. Then, the central processing unit 60 finds the line circuit 31 on the slope call side connected to the line circuit 30 from the connection table, and connects the display terminal paired with the seventh line circuit 31 with the signal converter 40. Close the communication path between. The central processing unit 60 then provides the signal conversion device 40 with the received push button number. The signal conversion device 40 selects a message from the given numbers and provides the stored code string to the display 22 via the communication path switch 50. Display 'a22 stores the received code string and displays the message through a character generator. On the other hand, after the code string has been accumulated, the signal converter 40 and the electronics of the display 22 are connected and the communication path switch 50 is restored for 7 seconds, so that the signal converter 40 can be used for another display. Become.

In the above embodiment, the PB telephone 10 and the line circuit 30 handle the PB double signal as a dial signal, but there is no problem even if the dial signal is an impulse signal from a rotary dial instead of the PB double signal. The present invention can be carried out in exactly the same way by using a rotary dial filling machine and a line circuit for detecting dial impulses. In order to avoid imparting impulse noise to the other party, once the line circuit 30 gets used to the first impulse, a method of not relaying the pulse to the other party can be developed.

FIG. 2 is a block diagram of another embodiment of the present invention. Like in FIG. 1, the exchange is an electronic exchange, but unlike the case in FIG. The PBL signal receiver 34 is not connected to the signal converter 400.
This shows a case where a general PB telephone is connected to the specific terminal 20, but it is relatively rare to use the display 22 to transmit a message.
It provides an economically viable means of implementation. Note that the symbols in FIG. 2 that are the same as those in FIG. 1 represent the same functions.

Line circuits 32 and 33 connected to PB'1 and depletion 10 and 21 respectively have standard line circuit functions, such as supplying terminal ultra-fine/recovery monitoring 9 call current, etc.
The PB signal receiver monitors the terminal and, if detected at 7 times during a call, requests the central processing unit 60 to connect to the signal converter 41 .

Therefore, after the PB telephone 10 is connected to the specific terminal 20 via the communication path switch 50, the central processing unit 60 connects the line circuit 32 and the line (b) path 33 by hooking from the PB telephone 10. With the switch 50 left as is, the C1 line circuit 32 and the FB signal receiver connect the signal converter 410 to the PB13 receiver 34, and connect the display 2 of the specific foam terminal 20 that is also communicating with the signal converter 40.
The connection path with the second accommodation terminal and the seven communication path switch 50 are configured. Therefore, when the FB signal receiver 34 receives the dial digit information corresponding to the message from the PBi talk machine, this information is immediately given to the signal converter 40 and the first
As in the illustrated embodiment, a code string representing a message is applied to the display 22. The display unit 22 stores this code string and displays it as a message.
This is the same as in the illustrated embodiment. However, in the embodiment shown in FIG. 1, the connection path of the decoding converter f, 40 is restored to the code string sending condition in preparation for another service request, but in this embodiment, the message is transferred again, and the switching is performed each time. In order to avoid the trouble of making a call, the connection path is put on hold until the eldest caller.

It should be noted that in the above embodiment as well, an impulse signal from a rotary dial may be used instead of the <PB flaw signal as in the embodiment of FIG. 1. Moreover, when using the rotary dial, the first number is 1 instead of the shoe king.
can be dialed to configure a connection path to the FB signal receiver 34.

FIG. 3 is a block diagram of still another embodiment of the present invention.
As shown in the figure, the exchange is an electronic exchange.

In this embodiment, the No. 1g changing device 40 constantly changes the line/control of the telephone 21 of the specific terminal 20 via the dial signal receiver 37.
In addition to being connected to the circuit 36, the output of the signal conversion device 40 is also constantly connected to the display 22.

Therefore, an effective connection means is provided when a telephone connected to a specific terminal wants to frequently send messages to the display.

General PB'! The line circuit 35 that intersects the filling machine only has a standard line monitoring function and a communication current supply function, and rarely needs to have a 7-bit/g detection function. The dial code from the general PB telephone 10 can always be received by the dial receiver 437 connected to the line circuit 36 of the specific terminal 20 and immediately sent to the signal converter 40.

Therefore, the signal conversion device 40 can immediately display the message corresponding to the dialed number on the display 22, as in the case of FIGS. 1 and 2.

It is clear that in the above embodiments as well as in the case of FIGS. 1 and 2, the same VC invention can be carried out by using a dial impulse signal instead of the FB multiplied signal.

Furthermore, in the embodiments of the present invention shown in FIGS. 1, 2, and 3, the exchange is an electronic exchange, but if it is a common control exchange, it will be a crossbar type exchange, and there is no problem in the main direction. .

Furthermore, in the above-mentioned embodiment, the Ig number conversion device 40 encodes a character string representing a message character by character and stores it as a code string, and assigns a number to each message type. A code string is selected upon receiving the numerical information representing the code. However, the message may be stored as a pattern on the display screen without being encoded. In this case, a character generator is not required for the display, but it is advantageous to have a pattern memory for one screen. Note that the memories used in these signal conversion devices and used in storage devices and displays can be easily constructed from integrated circuits, floppy disks, and the like.

(Effects of the Invention) As explained in detail above, the present invention enables not only voice calls to a specific terminal, but also messages with predetermined multiplicity.
T? Since it can be forwarded by adding f ¥ 1, there are many foreign customers, and the story goes that it is attached to the telephone equipment of hotels, etc., and is effective for communicating. The present invention also has the advantage that by using the message memory of the signal conversion device, it can be easily used as a message service even when the other party is busy talking.
