I.Background of Donjin e-Fax Service

“e-Fax” is a value-added telecommunication service that combines the fax and email together. The “e-Fax” user will be assigned with a telephone number to function as the dedicated fax number and with an email address as same as this fax number. Thus, when a user is sending faxes, and especially, some faxes in the form of electronic documents, it is possible to send out these faxes through the Internet without the need of either printing or telephone lines. Besides, the user can also complete the receiving of faxes over the Internet, so that the operations can be simplified and costs can be saved. However the address of an “e-Fax” user changes, his/her fax number will never changed. Even if this user is in other places or abroad, he/she can receive faxes in a most cost-efficient way. Furthermore, the email address can be easier to remember, and can be more helpful to the storage and management of faxes. For corporate users, the extension function of e-Fax service can be seamlessly integrated with the business enterprise post office so that enterprises can readily manage their own fax communications, while the super capacity group sending function of this service can realize the easy transmission of 10,000 faxes.


1.1 User Demands

Development of telecommunication technologies has led to an exceptional exuberance of information exchange means such as E-mail, IM, and SMS and so on, yet fax communication as one of most traditional communication approaches has always retained a higher utilization rate. According to statistics, the amount of information transmitted by means of faxes would account for 63% of total load of information in the manufacturing industries. Yet some problems also exist in the fax uses.

The first problem would be the management of faxes. In such enterprises as foreign trade, logistics and tourism companies where there would be frequent exchange of faxes, the number of faxes received per day would be often counted in several hundreds. Due to the paper property of fax documents, they can not be preserved for a long period, while there is also a lack of uniform standards and yardsticks for the distribution, arrangement, filing and retrieval of faxes. As a result, the management on faxes can become extremely difficult. Meanwhile, the amount of information that an enterprise sends out per day can be likewise substantial, where there are often such critical commercial correspondence papers as contracts and orders. A huge load of sending of faxes can also give rise to such abnormally complicated processes as drafting, approval and countersignature for faxes. A common case is that a critical fax to be sent can be circulated with some other unimportant faxes in the approval process of an enterprise, thus reducing the business efficiency of this enterprise to a certain degree. Faxes can be frequently exchanged between different enterprises; while there can be various levels of importance and sensitivity of fax contents. However, it is often hard to differentiate these faxes by means of the currently available traditional monitoring measures. Therefore, enterprises would have urgent demands for an effective fax management solution.


The secondary problem would be the junk faxes. Due to continual increases in the amount of social information, there has been a surge in the emergence of various kinds of useful or useless information from all quarters, while business enterprises would more often than not set up their fax machines into the state of auto receiving or sending just in case of miss of any critical fax. Consequently, it is impossible for fax machines to carry out an effective filtering of the received information, thus creating a sharp increase in the amount of junk faxes.    

According to investigations, nearly 42% of faxes would be junk faxes in a small or medium enterprise. The increased junk faxes would not only compound the mechanical wear of fax machines and consumption of toner and papers thereof, but also lead to a rise in corporate manpower costs and business costs in that business enterprises often tend to assign special personnel to search among a great pile of faxes for valid ones. 


1.2 Demands of Telecommunication Operators

Subsequent to the changes of telecommunication mechanism in recent years, there has been further development of telecommunication technologies , while the telecommunication market has entered into a phase of mutual competition between multiple operators. Nearly no discrepancy exists between the basic telecommunication services provided by different telecommunication operators, while the charging strategies of each of these operators can be easily simulated by its competitors. As such, competitions in the basic telecommunication services have become significantly intensified to result in a case of increase in the number of users with no increase in revenues and decrease in the ARPU of users. 

Exacerbation of competitions requires the telecommunication operators to further expand the volume of their services through service creations, and attain the continual growth of their revenues. While telecommunication operators are also making efforts to drive their business growth by way of data services, such services can account for insignificant shares of their total business volume all the way. According to statistics, voice services can still occupy over 80% of total business volume and especially for fixed telephone network operators, revenues accruing from their basic telecommunication services would nearly account for more than 90% of their total revenues. Therefore, Donjin Tech believes that such creations in terms of basic telecommunication services as the management of business opportunities in call traffic, integration of old and new services and organic merge of basic services and value-added voice services can provide a driving force to the effective growth in the basic telecommunication services.

Among the clients to telecommunication operators, those commercial customers and high-end personal users can play an important role in supporting the service volume. The so-called satisfaction of service needs of commercial customers refers to the practice that telecommunication operators would carry out an in-depth analysis of business modes and features of their commercial customers, make the full exploitation of service needs of such commercial customers, and embed different types of basic telecommunication service into the business processes and business logics of these customers in order to enhance and enrich the business means and methods of commercial customers and thus promote their market sales. Based on the intrinsic differentiation of their business management and their meticulous operations of low costs that are customer-oriented, these telecommunication operators can well realize a win-win situation with their commercial customers.

In those basic telecommunication services targeted at commercial customers, fax communication serves as a critical service just secondary to voice services, where the Donjin e-fax service serves just as a key creation to traditional fax services.
