In the modern presentation multimedia we now have the technology that can begin to movetowards an ability already held by the human beings in that by using computer, technology,software and other technology, such as CD-ROM not only can we bring together audio andvisual images but interactive with other computer users.10、为弥补这些问题，要在基本结构中加入大量的高效中继线。
高效中继线用于直接连接有大量的节点间通信业务量的各交换中心。
通信量常常是通过网络中可用的最低层次传送的。
To compensate for these problems, a large number of high usage trunks augment the basicarchitecture. High-usage trunks are used for direct connection between switchingcenters with high volumes of internodes traffic. Traffic is always routed through thelowest available level of the work.11、光纤网络的革命刚刚开始，并正快速向未来的带宽无线、可靠和低费用的在线世界发展。

通信工程专业英语教程
通信工程专业英语教程The field of communication engineering has experienced remarkable advancements in recent years, driven by the rapid technological progress and the ever-increasing demand for efficient and reliable communication systems. As the world becomes more interconnected, the role of communication engineers in shaping the future of global communication networks has become increasingly crucial. To meet the evolving needs of this dynamic industry, the development of a comprehensive and well-structured English curriculum for communication engineering majors is of paramount importance.The primary objective of an English curriculum for communication engineering students should be to equip them with the necessary language skills and technical knowledge to effectively navigate the global landscape of communication technologies. This curriculum should be designed to not only enhance their proficiency in English but also to provide them with a deep understanding of the specialized terminology, concepts, and methodologies relevant to their field of study.One of the core components of such a curriculum should be a strong emphasis on technical writing and communication. Communication engineers are often required to prepare technical reports, proposals, and presentations, which necessitate the ability to convey complex information in a clear, concise, and professional manner. The English curriculum should therefore include courses that focus on technical writing, report writing, and professional communication, providing students with the opportunity to develop these essential skills.In addition to technical writing, the curriculum should also incorporate language training that caters to the specific needs of communication engineers. This may include courses on academic English, scientific and engineering English, as well as English for specific purposes (ESP) courses that cover topics such as telecommunication systems, signal processing, and network protocols. By providing students with a solid foundation in the language used in their field, they will be better equipped to engage in discussions, read and comprehend technical literature, and collaborate with international colleagues.Another crucial aspect of the English curriculum for communication engineering majors should be the integration of project-based learning. This approach allows students to apply their language and technical skills in real-world scenarios, fostering their ability to work in teams, solve complex problems, and communicate effectively withdiverse stakeholders. Such projects may involve the design and implementation of communication systems, the analysis of network performance, or the development of innovative communication technologies.Furthermore, the curriculum should incorporate opportunities for students to engage in international collaborations and exchanges. This could include student exchange programs, virtual international team projects, or participation in global communication engineering conferences and workshops. These experiences not only enhance students' language proficiency but also expose them to different cultural perspectives and industry practices, preparing them for the global nature of the communication engineering field.To ensure the effectiveness of the English curriculum, it is essential to incorporate ongoing assessment and feedback mechanisms. This may include regular evaluations of students' language proficiency, technical knowledge, and communication skills, as well as feedback from industry partners and alumni to ensure the curriculum remains relevant and responsive to the evolving needs of the communication engineering sector.In conclusion, the development of a comprehensive English curriculum for communication engineering majors is a crucial step in preparing the next generation of communication professionals. Bycombining language instruction with technical knowledge and practical application, this curriculum will equip students with the necessary skills and competencies to thrive in the dynamic and globally interconnected world of communication engineering. As the demand for efficient and innovative communication systems continues to grow, the importance of a well-designed English curriculum cannot be overstated, as it will contribute to the development of highly skilled and globally-minded communication engineers who can drive the future of the industry.。

Ancient systems and optical telegraphy
Early telecommunications included smoke signals and drums. Talking drums1 were used by natives in Africa, New Guinea and South America, and smoke signals in North America and China. Contrary to what one might think, these systems were often used to do more than merely announce the presence of a military camp.
Telephone
The electric telephone was invented in the 1870s; it was based on earlier work with harmonic (multi-signal) telegraphs. The first commercial telephone services were set up in 1878 and 1879 on both sides of the Atlantic in the cities of New Haven and London. Alexander Graham Bell held the master patent for the telephone that was needed for such services in both countries. All other patents for electric telephone devices and features flowed from this master patent.

Communication over Networks
Being able to reliably communicate to anyone, anywhere, is becoming increasingly important to our personal and business lives. In order to support the immediate delivery of the millions of messages being exchanged between people all over the world, we rely on a web of interconnected networks. These data or information networks vary in size and capabilities, but all networks have four basic elements in common:
The external factors affecting communication are related to the complexity of the network and the number of devices a message must pass through on its route to its final destination.
The development of Communication
（1）In ancient times ，information could be transferred through light or sound。
