Abstract

PURPOSE:To provide a facsimile equipment in which whether or not the classification of a connected DP line is 10pps or 20pps can be automatically recognized. CONSTITUTION:A tone detecting part 3 detects a dial tone inputted from a dial line 5, and communicates it to a control part 1. The control part 1 controls a dial pulse signal generating part 2, and allows the dial pulse signal generating part 2 to transmit a 20pps dial pulse to a line. A tone signal from the line is detected by the tone detecting part 3 within a fixed time just after the transmission of the 20pps dial pulse. At that time, when the tone detection is not judged from a communicated content from the tone detecting part 3 to the control part 1, the control part 1 recognizes the connection of a 20pps DP line, and when the tone detection is judged from the communicated content from the tone detecting part 3 to the control part 1, the control part 1 recognizes the connection of a 10pps DP line. And also, the recognized classification of the DP line can be held in a storage circuit part 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a faricilim device, and more particularly to a line type discrimination system for dial lines.

[0002]

2. Description of the Related Art A conventional Falisimili device has a line type changeover switch, and the changeover switch is manually changed according to the type of dial line to be connected.

When connecting the Farisimili device to the dial line, it is necessary to set it according to the type of dial line to which the Farisimili device is connected. The installer investigates the type of dial line to be connected and matches the type of dial line. I had to change the switch manually.

[0004]

However, in the conventional Falisimili device, since the changeover switch is manually changed according to the type of dial line to be connected as described above, unattended operation cannot be performed.

Further, there is a drawback in that the setting of the Farisimili device suitable for the type of dial line to be connected cannot be automatically performed. Furthermore, when the telephone line to which the subscriber is subscribed has a dial pulse of 20 pps, the setting of the connected Farisimili is a dial pulse of 10 pps, and even if a dial call is made, the subscriber telephone network side does not accept the 10 pps dial pulse. The dial tone remains on.

The same applies when the subscriber telephone line is 10 pps and the farsimile setting is 20 pps.

The present invention has heretofore been made in view of the above-mentioned circumstances, and therefore an object of the present invention is to provide a novel facilitary apparatus capable of eliminating the above-mentioned drawbacks inherent in the conventional art. It is in.

[0008]

In order to achieve the above object, a faricilimi device according to the present invention comprises a tone detector for detecting the type and presence of a tone input from a line, and
A dial pulse signal generator that sends out 0 pps dial pulses and 10 pps dial pulses, and a tone detector that informs the presence / absence of a tone input from the line after sending 20 pps dial pulses to the line by controlling this dial pulse generator. It is configured to include a control unit that automatically determines the type of the dial line of 20 pps and 10 pps, and a storage circuit unit that stores the type of the dial line determined by the control unit.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will now be described in detail with reference to the accompanying drawings with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a faricily apparatus according to the present invention.

With reference to FIG. 1, an embodiment of a faricilimi device according to the present invention comprises a tone detector 3 for detecting the type and presence / absence of a tone input from a dial line 5, and 20.
Dial pulse signal generator 2 for sending pps dial pulse and 10 pps dial pulse to dial line 5
By controlling the dial pulse signal generator 2 to send a 20 pps dial pulse to the dial line 5 and recognizing the presence or absence of a tone input from the dial line 5 after sending by the notification from the tone detector 3, The control unit 1 automatically discriminates the type, and the storage circuit unit 4 stores the type of the dial line 5 automatically discriminated by the control unit 1 by the notification from the control unit 1.

FIG. 2 is a flow chart showing the operation of the faricily apparatus according to the present invention.

The contents of claim 1 according to the present invention will be described below with reference to the block diagram of FIG. 1 and the flowchart of FIG.

Referring to FIGS. 1 and 2, the dial line 5
In the Farisimili device connected to, the tone detection unit 3 performs the dial tone detection 101 input from the dial line 5. The tone detection unit 3 that has detected the dial tone sends a dial tone detection notification 102 to the control unit 1. Control unit 1 that recognizes the detection of dial tone
Controls the dial pulse signal generator 2 to perform 20 pps dial pulse transmission 103 to the dial line 5. 20
Within a certain time after sending the pps dial pulse,
The tone detection unit 3 performs the presence / absence detection 104 of the tone input from the dial line 5 and notifies the control unit 1 of the detection result.

When the tone detection presence / absence notification from the tone detection unit 3 to the control unit 1 is the tone detection absence notification 105,
The control unit 1 recognizes 106 the dial line type of 20 pps. When the tone detection presence / absence notification is the tone detection presence notification 107, the control unit 1 recognizes 108 the dial line type 10 pps.

Based on the contents described above, the control unit 1 automatically determines the line type of the dial line 5 to be connected.

Next, the content of claim 2 according to the present invention will be described with reference to the block diagram of FIG.

Referring to FIG. 1, in the description of claim 1, the control unit 1 that automatically determines the type of the dial line 5 is used.
Notifies the storage circuit unit 4 of the determined type of dial line 5. The storage circuit unit 4 stores the type of the dial line 5 in response to the notification from the control unit 1.

Thereafter, the control unit 1 reads the type of the dial line 5 from the storage circuit unit 4 and stores the stored dial line 5.
Dial pulse generator 2 with the same dial pulse as
To send to the dial line 5.

[0020]

As described above, according to the falisimili device of the present invention, the type of connected dial line can be automatically determined and the type of dial line can be stored. This has the effect of automating the setting of the Farisimili device suitable for the type of dial line.
