JPH08223319A - Information exchange provided with a telephone line type discrimination circuit - Google Patents

Abstract

PURPOSE: To discriminates a type of a telephone line automatically or semi- automatically by providing a circuit to send sequentially a call signal depending on each type of telephone lines and discriminate the type of the line based on an accepted call signal. CONSTITUTION: When the operation of a line type discrimination circuit 14 is started, an exchange 3 is connected to a telephone line 4. Then a DTMF pulse for a touch-tone line is generated at first and a call signal of dial 0 is sent to a telephone line 4 through a communication control circuit 13 and an exchange 3 by using the DTMF pulse. In this case, when the line type is correct, no tone is caused but when the line type is different, since a dial tone is produced, then the presence of the dial tone is discriminated. As a result of the discrimination, when no dial tone is detected, it indicates that the line type is correct.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information exchange apparatus for receiving desired information from an information distribution apparatus having a database through a telephone line and using the same, and more particularly to multimedia such as karaoke song data and game data. The present invention relates to an information exchange device that uses information and is configured to automatically or semi-automatically determine the type of a user's telephone line at the time of installation.

[0002]

2. Description of the Related Art In recent years, an information exchange system in which desired information recorded in a central database can be called and used by a terminal through a telephone line has entered a practical stage, and a user can use it to perform personal computer communication. , Karaoke song data, game data, stock information, weather information,
Various information such as town information can now be obtained and used.

When exchanging information between these information processing devices through a telephone line, a MODEM (modulator / demodulator) or a communication control circuit is used. These MOD
When connecting an EM, etc. to a telephone line, there are three types of telephone lines to which the MODEM, etc. is connected (push line, dial line 10 pps, 20 pps). Will be done.)
It is necessary to check the specifications of the input / output circuit of the MODEM or the like with the specifications of the telephone line, but since a normal user does not know the specifications of the telephone line owned by the user, there are many troubles.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and its purpose is to enable automatic or semi-automatic determination of the type of telephone line. The object is to provide the configured information exchange device.

[0005]

SUMMARY OF THE INVENTION The above object is to provide an information exchange apparatus for receiving and using desired information from a database through a telephone line, by sequentially transmitting a call signal for each type of telephone line, and receiving an accepted call signal. This can be achieved by an information exchange device characterized in that a circuit for determining the type of line is provided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings. FIG. 1 is a block diagram showing an overall configuration of an embodiment of an information exchange apparatus according to the present invention, FIG. 2 is a flow chart showing the operation of the line type determination circuit, and FIGS.
6 is a flowchart showing an operation when a user sets his / her own registration number and the like in the information exchange device according to the present invention.

In FIG. 1, 1 is an information exchange apparatus according to the present invention,
11 is the terminal device, 12 is a remote control device for operating the terminal device, 13 is a MODEM or other communication control circuit,
Reference numeral 14 is a line type determination circuit, 2 is a user's telephone, 3 is an exchange, 4 is a telephone line, 5 is a database on the information provider side, 6 is an exchange, and 7 is a telephone on the information provider side.

A user operates a terminal device 1 such as a karaoke device.
In order to newly install the information exchange apparatus 1 including 1 and to communicate with the information provider through the telephone line 4, it is necessary to adapt the input / output circuit of the communication control circuit 13 to the type of the telephone line 4. Therefore, the type of the telephone line 4 needs to be determined.
It is automatically performed according to the procedure shown in.

That is, in FIG. 2, when the operation of the line type determination circuit 14 is started in the first step "START" indicated by 21, the second step "OFF" indicated by 22.
-HOOK ", the exchange 3 is connected to the telephone line 4. Next, in the third step indicated by 23, a DTMF pulse for the push line is first issued, and the DTMF
The fourth step "DIAL" indicated by 24 by the pulse
In "0", a calling signal of dial "0" is sent to the telephone line 4 through the communication control circuit 13 and the exchange 3. At this time, if the line type is correct (that is, in this case,
If it is a push line, there will be no sound, but if it is different, a dial tone of "Two" will occur, so the presence or absence of this is indicated by the fifth step "DIAL TONE".
? ] To determine. If the result of this determination is “NO”, that is, if the dial tone is not detected, it means that the line type is correct (it is a push line).
In the sixth step "ON-HOOK" shown by a, the connection with the telephone line 4 is cut off, and the setting that the line type is the push line is saved and set, and the seventh step "EN" shown by 27
D ”, the line type determination work ends.

On the other hand, the fifth step "DIAL" indicated by 25
TONE? If the determination result in “” is “YES”, that is, the dial tone “Two” is detected,
Since it indicates that the line type is different (other than push line), the sixth step "ON-HO" indicated by 26b.
"OK", once the connection to the telephone line 4 was cut off, and then 2
Returning to step "OFF-HOOK" shown in 2, the exchange 3 is connected to the telephone line 4. Then, in the step indicated by 23, this time 20p for the dial line 20pps
A ps dial pulse is emitted, which causes 2
In step "DIAL" 0 "" shown at 4, the dialing signal of the dial "0" is sent to the telephone line 4 through the communication control circuit 13 and the exchange 3. At this time, if the line type is correct (that is, if the dial line is 20 pps in this case), there will be no sound, and if they are different, a dial tone of "two" will occur. ? ], And if the result of this determination is “NO”, then 26a
And 27, the setting that the line type is the dial line 20 pps is stored and set.

Again, the "DIAL TONE" indicated by 25
? Is YES, the process returns to step "OFF-HOOK" indicated by 22 again, and this time, a calling signal is issued by a 10 pps dial pulse for the dial line 10 pps and the same judgment is performed.

By the above operation of the line type determination circuit 14, the type of the telephone line 4 used by the user is automatically determined, and the result is displayed on the display screen of the terminal device 11. Seeing this, the line type is manually registered in the information exchange device or is automatically registered in the information exchange device.

In addition, "DIAL TONE" indicated by 25
? The detection of the dial tone in the step of "" is an operation of recognizing a signal of 400 Hz called "two", and therefore can be detected by using an LSI for telecontrol or the like.

FIGS. 3 to 5 are flow charts for executing a series of operations for performing telephone number registration, telephone line type determination, password registration, karaoke piece reservation, and karaoke performance in the information exchange apparatus according to the present invention. Of which
The display contents on the display screen of the terminal device 11 in the first "display explanation screen" step in FIG. 3 are shown in FIG.
