随着传真通信的发展,三类传真机得到了广泛应用,传真技术正向着高速化、网络化、保密化和多媒体化等方向发展。文中研究分析了采用V.34建议的高速传真通信规程,阐述了高速传真网关的基本原理。本设计依据系统的具体需求,移植了uC/OS-II实时操作系统,完成了系统的初始化工作以及系统上电自检过程,实现了高速传真网关,满足了系统的开发需求。
With the development of facsimile communication, the three types of facsimile machines have been widely used, and the facsimile technology is developing in the direction of high speed, network, confidentiality and multimedia. This paper analyzes and analyzes the high speed fax communication protocol based on V.34 and expounds the basic principle of high speed fax gateway. The design based on the specific needs of the system, transplanted uC / OS-II real-time operating system, completed the system initialization and system power-on self-test process, to achieve a high-speed fax gateway to meet the system development needs.
