JPS6384241A - Message tone transmission system - Google Patents

Abstract

PURPOSE:To prevent unnoticed or looked over even though a message is displayed by sending a special tone to a caller side terminal equipment in calling a terminal equipment with the presence of a message. CONSTITUTION:A message key is depressed at a terminal equipment 1n, a message number is inputted from a dial pad and the message key is depressed again, the message is set in the memory of an main equipment 2. Then when other terminal equipment 11 dials to call the terminal equipment 1n, a guide display is given to the display device of the terminal equipment 11. As soon as the terminal equipment 1n is called according to the display, a special tone representing the presence of a message is returned from the equipment 2. The special tone is changed into a conventional ring tone and the message of the terminal equipment 1n is displayed on the display device of the terminal equipment 11. Thus, the looking over of the display is avoided.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a message transmission system in a key telephone device or the like.

(Prior Art) Conventionally, message transmission in a key telephone device is performed in the following format.

In this system, when another terminal in the system calls a terminal that has a message stored in its memory in advance, if a certain period of time elapses without the called party responding, the message is sent to the calling party's terminal. This method displays a message that the caller has stored in memory. To briefly explain this message display example, if the 25th terminal sets a message, other terminals in the system
When the second terminal is called, the dialed terminal number is displayed on the display of the calling terminal, and if a certain period of time elapses without the called party responding, the display changes to a message.

In the conventional message transmission system as described above, the same callback tone is returned to the caller regardless of whether the called party has set a message or not. Therefore, the state of the calling terminal when the dial was displayed before the message was displayed was no different from a normal extension call when the called party had not set up a message, regarding the ringback tone. .

(Problems to be Solved by the Invention) As described above, in the conventional message transmission system in key telephone devices, etc., only the display on the display is handled,
Tone was not considered at all. For this reason, when calling the other party, the caller may not notice the other party's message displayed on the display on his or her own terminal.
There was a problem with things being overlooked.

Therefore, the present invention is directed to the above-mentioned conventional button telephone equipment, f1
This system was developed to improve the message transmission system used in other systems, and its purpose is to use audible sounds to notify the caller of the presence or absence of a message from the called party.

[Structure of the invention]

(Means for Solving the Problems) The present invention includes means for transmitting a special sound to the calling terminal when a terminal with a message is called.

(Function) Since the present invention adopts the above-described configuration, it is possible to generate a special sound to inform the calling terminal that has made a call to a terminal with a message that a message is stored.

(Example) FIG. 1 is a block diagram showing an example of the present invention.
m is the terminal, 2 is the main device, 3~3m is the interface circuit with the terminal, 4 is the control circuit, 5~5m is the interface circuit with the office line, 6~6 is the office line, 7 is the tone generation trunk circuit (TOU) ).

FIG. 2 is a top view of the terminal shown in FIG. 1, where 11 is a handset, 12 is a display, 13 is a dial pad, and 14 is other function keys including a central office line, an extension line, and a message key.

When setting a message, the dial pad 13 and function keys 14 are used. Also, the message is displayed on display 1.
2.

FIG. 3 is a diagram for explaining an example of a message setting method. To set a message, press the message key (MSG) on the device and press the message number (1 to 4).
0 (specify one of the four types of messages) from the dial pad, and then press the message key (MSG) again.
). Then, the main device automatically moves the message to the message area of each terminal, which has been previously stored in the memory, and completes the setting. Further, to cancel the message setting, operate the dial "5" and similarly press the message key (MSG) again. This situation is shown in FIG.

FIG. 4 is a simple configuration diagram of the main device and the terminal. 2 is main outfit C
11 to ln represent terminals, ln is the terminal of A-25,
1, to 16 are terminals A10 to /I&15.

Now @BACK AT 3:00 on Ya25 terminal
Assume that a message PM' is set using the method described above. And after that, another terminal (say AIO)
When the user calls the terminal 1o of A-25 by dialing, the display on the terminal 11 of A10 becomes as shown in FIG. First, grab the extension (Fig. 5-51) and dial r2Jr5J (Fig. 5-52). The terminal 1n of mu 25 is called and at the same time a special tone indicating "1 message available" is sent back. The special tone changes to a normal ringback tone and the display displays a message from the called party (Figure 5-53).

When a terminal with a message is called, the tone to be given to the caller may be as shown in FIG. 6, for example. In the example shown in Figure 6, after the caller grabs the extension and dials the number, a tone of 4 is used to indicate that there is a message from the called party.
An intermittent sound of 00Hz and approximately 80m5 is returned for approximately 1 second. After that, a normal ringback tone (1 second on, 3 seconds off cycle) is returned.

Figure 2g7 is a diagram showing an example of a memory for writing a message. Each terminal has a corresponding storage area for 16 characters, and can store multiple characters, numbers, etc. In the figure, the memory contents of terminals M10 to 24, which do not have a message setting, contain FFH, and terminals with messages have FFH.
On p&25 - BACK AT 3:00
A code corresponding to "PM" is stored in ASCII format.

FIG. 8 is a flowchart showing the sequence of sending out this special tone. Perform Φ-manpower with l (step 8
1), if the input is the INT (extension) key (step 82
), turns on the INT key flag in the rewritable memory (step 83).

If it is not the INT key (step 82), a check is made to see if the input is a dialed terminal number, and if the input is a terminal number that exists in the system (step 84), the INT key is pressed in the next step 85. If it is determined that the dial operation was performed after the INT key was pressed (step 87), the message area corresponding to the input dial (Figure 7) is checked to see if there is a message (step 87). 87.88). If a message is set on the other party's terminal, message tone transmission processing and message display processing are performed in step 89, and then normal ringback tone transmission processing is performed (step 90).

The message tone and ringback tone generate periodic sounds as shown in Figure 6 by turning on and off the XP (call path) in TOU7 shown in Figure 1 and the XP corresponding to the calling terminal in 5TU3. - Sent. Here, TOU7
A 400Hz sound source is available.

〔Effect of the invention〕

As explained above, when the calling party calls the called party, the calling party can obtain information from the sound as to whether or not the called party has left a message. Therefore, there is an advantage that when an extension call is made, it is possible to prevent the problem of overlooking or not noticing the message display even if the other party has already set a message.
