Network fax is fax storage based on PSTN (Switched Network) and the Internet, also known as electronic fax. It integrates the best network, intelligent network and Internet technology. The principle is to transfer files to a fax server through the Internet, which converts them into a common graphic format received by the fax machine, and then sends them to ordinary fax machines around the world through PSTN.

There are three common definitions of network fax: network fax.

1.Network fax, also known as electronic fax, known as efax in English, is a fusion of traditional telecommunication lines (PSTN) and soft switching technology (NGN), without the need to purchase any hardware (fax machine, consumables) and software of high-tech fax communication products. 2.

Network fax is fax storage based on PSTN (Switched Network) and the Internet, also known as electronic fax. It integrates the best network, intelligent network and Internet technology. The principle is to transmit files to the Eastfax fax server over the Internet, which converts them into a common graphic format received by the fax machine, and then sends them to ordinary fax machines or any electronic fax number around the world via PSTN.

3.Network fax refers to a new type of fax method that sends and receives faxes through the Internet and does not require traditional fax machines. Through the fax, users can receive and send faxes as if they were sending and receiving e-mails, which has the advantages of convenience, environmental protection, and easy management.

In the literal sense, this is to use a computer to send and receive faxes. Electronic fax is divided into two situations: the first is to install certain hardware (such as fax cat, fax card, etc.) on the computer, install a software system that matches the hardware, and finally connect the first line to the hardware, so that you can use the computer to send and receive faxes.

This electronic fax principle is the same as the traditional fax machine, and it also sends and receives fax through the ** line.

The second type of electronic fax does not require any specific software or hardware to be installed on the computer, but rather to operate electronics on the computer.

Send and receive faxes like mail. This type of electronic fax is an interconnected network that sends a fax signal to a specific fax server (provided by an electronic fax service provider) and then from that server** to the corresponding fax machine or computer. The electronic fax system integrates the computer Internet and PSTN** network to realize mobile fax sending and receiving.

This is also what we commonly refer to as web faxing.

To sum up, network fax refers to two kinds of electronic fax, that is, electronic fax in a narrow sense. Generally speaking, electronic fax should also be referred to as network fax.

Electronic fax is a high-tech fax communication product that integrates traditional telecommunication lines (PSTN) and softswitch technology (NGN) without purchasing any hardware (fax machine, consumables) and software. It integrates the best network, intelligent network and Internet technology. E-fax (.e.b.)

The principle is to transmit the file to the fax server through the Internet, and the server converts it into a common graphic format received by the fax machine, and then sends it to the ordinary fax machine or any electronic fax number around the world through PSTN.

Fax, known as fax in English.

To put it simply: it refers to the transmission of authentic handwritings such as **, charts, letters, documents, etc. to distant places through wired or radio devices.

The working principle of the fax machine: The working principle of the fax machine is very simple, that is, it first scans the file that needs to be sent and converts it into a series of black and white dot information, and then converts the information into an audio signal and transmits it through the traditional ** line. The receiver's fax machine"Hear"After the signal, the corresponding point information is printed out so that the receiver receives a copy of the original sent document.

But the way this kind of fax machine prints after receiving the signal is different, and the difference in their working principle is basically in these aspects.

The actual operation of the fax machine: you can look at the manual, simply say that you only need to write the article or a certain document, gently insert the fax machine file input port, dial the fax number of the other party, after the other party replies, press the "start" (some are "send") button, and it's done!

It is that the other party's documents are copied directly to your hand, which requires a fax machine.
