There are three common definitions of network fax:

1. Network fax, also called electronic fax, is called efax in English. It is a high-tech facsimile communication product that combines traditional telecommunication line (PSTN) and soft switch technology (NGN) without buying any hardware (fax machine, consumables) and software.

2. Network fax is the fax storage and forwarding based on PSTN (Telephone Switching Network) and Internet, also known as electronic fax. It combines telephone network, intelligent network and internet technology. The principle is that the file is transmitted to the fax server through the Internet, converted into the general graphic format received by the fax machine, and then sent to the ordinary fax machine or any electronic fax number around the world through the PSTN.

3. Network fax refers to a new way of sending and receiving faxes through the Internet without the need of traditional fax machines. Through fax, users can send and receive faxes like e-mail, which has the advantages of convenience, environmental protection and easy management.

Facsimile types, advantages and disadvantages

1. Traditional fax machine: you need a telecom PSTN line, you need to buy a fax machine or moden (you must have a computer) to send and receive faxes through the telecom PSTN line;

Disadvantages: waste of consumables, slow sending time and unclear fax;

Advantages: the fax quality is stable and the success rate is over 95%;

2. Online fax software: fax software provided by computer manufacturers, which can be used by connecting the telephone line to the RJ 15 interface behind the computer through the program provided by the computer;

[Edit this paragraph] The development history of fax communication

Fax communication is a communication method that uses scanning and photoelectric conversion technology to transmit static images such as words, images and photos from the sender to the receiver through wired or wireless channels, and reproduce the original static images in the receiver in the form of records.

1843, American physicist Alexander Bess invented the fax machine according to the pendulum principle. 1850, christopher baker Weil in the United States began to replace Alexander Bain's pendulum mode with "roller and screw" device, which made fax technology take a step forward. 1865, Iranian Abakatri made a practical fax machine according to the principle put forward by Bain and Bakewell, and conducted fax communication experiments among French cities such as Paris, Lyon and Marseille. It can be seen that fax has a history of 150 years since its invention, but its popularity has been in recent decades. Prior to this, its development was very slow, mainly limited by the use conditions and backward technology. Since 1970s, countries all over the world have opened fax services on the public switched telephone network, and fax has been widely developed. Especially in 1980s, with the progress of fax machine standardization and the maturity of technology, it became the fastest developing non-voice service. To sum up, fax has gone through the following three stages from production to development;

(1) basic stage (1843— 1972)

At present, fax machines basically adopt mechanical scanning mode, and most of them adopt roller scanning. The circuit of fax machine adopts analog technology and discrete components. In terms of transmission, low-efficiency modulation technologies such as amplitude modulation and frequency modulation are adopted, and low-speed transmission is basically carried out by using special wired circuits. At this time, the application scope of fax is also very narrow, mainly used for news and weather broadcast.

(2) Development and promotion stage (1972-1980)

Since 1969, especially after 1972, fax has entered a new historical development period compared with ITT's progress in fax standardization and the development of fax technology itself. During this period, fax technology developed from analog to digital, mechanical scanning was replaced by solid-state electronic scanning, and low-speed transmission developed to high-speed transmission. Represented by document fax machine, its appearance and popularity have changed people's traditional views on fax machines and accelerated the development of fax communication. In addition, the application scope of fax has also expanded. In addition to transmitting documents, news photos and weather maps, it is also used in medical treatment, printing, book management, information consultation, financial data, electronic post and so on.

(3) Multifunctional Stage (after 1980)

At present, fax machine is not only widely used as communication equipment, but also plays an important role in office automation system and e-mail, and will transition to a comprehensive processing terminal. Now, it has been combined with microcomputer, using computer technology to increase the functions of fax in information collection, storage, processing and exchange, and gradually incorporated into the integrated services digital network (ISDN).

[Edit this paragraph] Purchase Guide

With the deepening of enterprise informatization, it is the only way for enterprises to bring fax into information management. In the face of the surging electronic fax market and a dazzling array of fax server software brands, how to choose the right products is particularly important. Buying a fax server can be considered from the following aspects:

1, system stability

Stable performance is the most basic index for selecting a fax server. Improper choice will lead to endless troubles. It mainly includes the following three reference items: first, see if the software will crash or paralysis after long-term operation; The second is to see if the software takes up too many system resources; The third is to see whether the server system (including software and hardware) can continue to bear the pressure of heavy workload without exception in the case of a particularly large number of faxes.

2. Applicability of functions

In addition to the basic sending and receiving functions, most fax software has also developed many auxiliary functions, such as sending and receiving emails, fax approval, fax signature, fax editing, SMS notification, voice function, multi-computer integration, group free fax, etc., which greatly facilitates our work. However, not all functions are necessary for every enterprise, and each software has its own uniqueness when realizing the same function, so it is necessary to choose the product that suits you according to the actual needs and the existing working environment.

3. Compatible with all kinds of fax equipment

At present, people are using various methods to send and receive faxes, such as fax machine, fax software, network fax, fax server, all-in-one machine and so on. Each method and equipment has many brands and models, which requires the fax server to have strong compatibility with fax signals given by various fax methods. According to statistics, under the same conditions, the success rate of fax server with low compatibility is less than 80%. The success rate of highly compatible fax servers can reach over 98%. Such obvious differences require us to pay special attention to the good compatibility of products when purchasing, so as to avoid the loss of the company's business caused by abnormal fax sending and receiving.

4. Extensibility of products

Enterprises should not only consider the existing fax lines, daily average fax volume, number of users, functional requirements, etc. , but also consider the upgrade and expansion after future business growth. If we can only meet the current demand, but can't meet the future expansion demand, it will not only bring repeated investment to enterprises, but more importantly, fax data can't be continued and managed uniformly.

5. Ease of use

In the fast-paced working environment, we require the software to be easy to use, easy to learn, as convenient and humanized as possible. After all, the computer level of employees in the company is uneven, and it is a headache to spend a lot of time and manpower on training, which is also a burden for employees.

6. Reasonable price

When the performance and function conditions are basically the same, price becomes the main consideration in selecting products. After all, affordable is the last word. Therefore, when shopping, you might as well shop around and choose "cheap and good quality" products in combination with your own cost positioning and the company's investment budget. At this point, the domestic fax server brand has obvious advantages.

7. Choosing a brand is choosing a service.

Although fax system is only a small member of enterprise information system, it plays an irreplaceable role for most enterprises. The lifeblood of sales, procurement, orders and contracts is inseparable from fax, which is also inextricably linked with other systems. Therefore, the service of fax software should not only be realized, but also need long-term protection. As a "soft power", service cannot be quantified or felt in advance, so it is necessary to conduct market research on various brands before buying, and look for products with good reputation and real strength among many brands. The foreign well-known brand worthy of recommendation is RightFax, and the domestic well-known brand is EastFax.
