Description of the Invention: [Technical Field to Which the Invention Is Ascribed] The present invention relates to a network, and relates to a technique applied to a network, and more particularly to a method. The function expansion system of the clothing is [previous technology] • The early communication system was transmitted by telephone. / : It is based on the telephone handset. Nowadays, the e-sports and speeds are the same as the applications of Gong Chenghua and computer technology. For example, the e-mail:::network environment can make it easy and effective to share on the computer. That is, the information of "communication, erp system, etc." and the format of the message format are new, and the traditional communication network architecture is changing. For example, the telephone system must swallow the mailbox service for 4', 17 The telephone exchange is connected by digital lines to a computer feeder that provides voicemail storage. Similar to this, in the traditional communication architecture, the network architecture becomes more and more complicated, resulting in high equipment and management costs, but the efficiency and security are greatly reduced. Since the 1990s, the Internet has been booming. The Internet Protocol (IP) has become the mainstream standard in the online world. In addition to the most common www services, people from all walks of life have begun to think about IP in other communication methods. Applications. Although the voice quality of the initial transmission over the Internet is not ideal, the network bandwidth is expanding, and with the improvement of data compression technology, IP voice transmission (Voice over IP; v〇Ip) becomes pure data transmission. Another important service in the Internet. 110163 5 200839528 One of the most important considerations for users to adopt VoIP is to reduce operating costs and communicate with the companies in the South. The VoIP-based lpt system replaces the public switched telephone network (called), which will greatly reduce the cost of voice transmission. In addition, IP it technology can integrate the traditional telephone network and information network into an IP communication network. Companies can benefit from reduced investment in network equipment, maintenance manpower and line costs. • ^白知's IP electro-active system 疋Using the existing Internet standard communication:: (Internet Protocol; Ip), the voice data through the network ^ ^ 〗 P electric tongue and the traditional telephone network Conversion gateway, class, telephone support and digital signal conversion processor (Digitai ^ Xian & 1': 〇CeSS〇r; DSP). Voice Gateway (Voice Gateway), and the general IP t is a user-side device. The Ip phone can be easily used as a network connection, and provides traditional analog phones and all functions. And can provide more complex communication services, such as browsing the WWW, receiving emails, and so on.隹J ΪΡ phone can provide more functions than traditional phone, but it is the same as the software, such as personal computer and other data processing devices = two network communication software IP phone Compared, stand-alone IP phones are less available. In order to solve this problem, the Ip phone developer has also proposed that the device can be connected to a network such as the 113 telephone, which provides more expansion functions of the network communication device. The standard extension of the network communication device function expansion technology is based on the specifications of the different developers, s system, road communication device or support function expansion module developer, design and manufacture to meet the specification The expansion interface and function 110163 6 200839528 group has relatively low selectivity for network communication devices or function expansion. Second, the expansion of the user function expansion module can also increase the cost of the manufacturer. How can we provide a kind of communication that can be applied to the existing universal communication == message, as a network communication device and network communication function 5, and then expand the link and carry out data transfer to provide the renewal network:: In order to solve the above-mentioned various shortcomings of the prior art, the present invention provides a universal communication communication specification communication communication, as a network communication = network communication function expansion The device is connected and data is transmitted, and the functions of the network communication device used for the expansion of the function of the road communication device are supplemented.

The fixing member is fixed to the first fixing portion and the second fixing portion, so that the network communication function expansion device and the network communication device are fixed to each other. In still another aspect of the present invention, the universal communication port and the extended communication port are one of RJ11, Universal Serial Port (usb) or eight IEEE 1394. The method for expanding the function of the network communication device of the present invention by using the network communication device function expansion system of the present invention includes: interconnecting the extended communication port with the universal communication port; and processing the data processing unit The network communication device generates a handshake according to a preset communication protocol, and causes the data processing unit to perform data processing including at least a codec for the data transmitted between the network communication device according to the preset communication protocol; The function expansion unit drives the corresponding function expansion module to perform an expansion function. In one aspect of the present invention, the method for expanding the function of the network communication device of the present invention further comprises providing a display unit, and causing the display unit to receive the driving of the tributary processing unit to correspondingly display the message processed by the data processing unit. . In still another aspect of the present invention, the universal communication transmission port and the extension communication device are RJn, Universal Serial Port (USB) or IEEE1394. Compared with the conventional network communication device function expansion technology, the 7-way communication device function expansion system and method of the present invention expands the general-purpose transmission rim and network communication function expansion device through the aforementioned network communication device Pass: fl: the link of the transmission: and the processing of the network communication device command and the control of the function expansion module by the data processing unit, that is, the communication transmission according to the existing common communication transmission specification 璋== specification 'Implementation of network communication device and network communication function expansion = connection ~, to provide the purpose of the network communication device 4 expansion.
