The "New Edition Telecommunications Technology Overview" provides a comprehensive guide to various aspects of the field. It commences with an introction to fundamental concepts, exploring signal types like sine waves, signal analysis, and the distinction between analog and digital signals. The book then delves into digital systems, focusing on SDH (Synchronous Digital Hierarchy), a standardized framework for digital transmission and synchronization in telecommunications.
Chapter 2 details the process of digitalization, discussing digital terminal technologies, such as A/D conversion and PCM systems, as well as synchronization techniques for ensuring data integrity. It further covers digital transmission methods, including baseband and bandpass transmission, and the intricacies of digital multiplexing like SDH's frame structure and its role in ISDN and B-ISDN.
Data communication technologies are the subject of Chapter 3, where the focus shifts to topics like network architecture, error detection, and the various types of networks like DDN (Digital Data Network) and the Internet, highlighting the role of TCP/IP and IP-VPN (IP Virtual Private Network).
The following chapters delve into fiber communication, discussing the principles, technologies, and advancements in optical fiber, including WDM (Wavelength Division Multiplexing) and the latest fiber types. The book also covers digital microwave and satellite communications, as well as mobile communication systems, from GSM to 3G and beyond, detailing the evolution and key technologies involved.
Access networks, including V5 and DSL (Digital Subscriber Line) connections, HFC (Hybrid Fiber Coaxial), and wireless options, are covered in depth, while the book also delves into the essentials of switching technologies, such as circuit switching, ATM, MPLS (Multiprotocol Label Switching), and soft switching, with a focus on signaling systems like No.7 and multimedia technologies, including compression, synchronization, and multimedia communication in the context of smart networks and TMN (Telecommunications Management Network).
Lastly, the book emphasizes the importance of security in modern telecommunications, exploring techniques for protecting against threats and ensuring the integrity of data in an increasingly digital landscape.
