Features: This book is divided into three parts, totaling 18 chapters. Part 1 consists of the first 10 chapters: Chapter 1 provides an overview of circuit-switching technology, packet-switching technology, and their development; Chapter 2 covers voice coding and digital transmission; Chapters 3 to 6 introduce the principles of digital switching, terminal equipment in digital switching systems, control methods of stored-program control (SPC) exchanges, program execution management, and the basic principles of call processing; Chapter 7 focuses on the fundamentals of switching technology, introducing basic call traffic knowledge, internal blocking in switching networks, and the system's call-handling capacity; Chapter 8 primarily discusses the concept, functions, and classification of signaling; Chapter 9 covers the services, functions, development, and applications of soft-switching systems; Chapter 10 mainly emphasizes applications, introducing the engineering design of switches, equipment usage, and management and maintenance. Part 2 primarily covers communication networks, including Chapters 11 to 17. Chapter 11 discusses public packet-switched data communication networks and the switching methods in data communication networks; Chapter 12 introduces B-ISDN broadband network technology, covering the basic concepts, characteristics, technologies, protocols, and connections of ISDN, as well as the services and applications of B-ISDN; Chapter 13 covers the technologies and access network solutions for broadband networks, briefly introducing wireless access methods, optical access networks, hybrid fiber-coaxial networks (HFC), and the applications of broadband networks; Chapter 14 discusses xDSL broadband network technology, covering modulation methods and classifications of xDSL, as well as an overview of ADSL, its working principles, coding technologies, protocol standards, applications, and development; Chapter 15 covers ATM asynchronous transfer mode, introducing the basic concepts of ATM, ATM switching systems, and ATM applications; Chapter 16 introduces the fundamental principles and implementation methods of optical switching technology, optical switching devices, and the development of optical switches; Chapter 17 covers intelligent networks, briefly introducing the architecture of intelligent networks, key technologies of broadband intelligent networks, and their applications. Part 3 (Chapter 18) is dedicated to practical training content. To facilitate readers in learning theoretical knowledge while acquiring practical skills, the book highlights the applied nature of higher vocational education. When designing and developing practical training projects, considerations such as new service function settings, operator console operation training, and system programming operations are fully taken into account. This book systematically introduces the principles of modern switching technology, the composition and applications of communication networks, and closely follows the mainstream technologies in the telecommunications industry. It emphasizes the integration of fundamental concepts, system structures, and practical application environments. This book is divided into three parts, totaling 18 chapters. Part 1 primarily introduces modern switching technology, covering topics such as the principles of digital switching, voice coding and digital transmission, switching technology parameters and metrics, terminal equipment in digital switching systems, control equipment in stored-program control exchanges, the basic principles of call processing, signaling methods, soft-switching technology, and typical examples of stored-program digital private branch exchanges (SPDNBX), as well as the engineering design, management, and maintenance of stored-program private branch exchanges. Part 2 primarily covers communication networks, including broadband network fundamentals, public packet-switched data communication networks, B-ISDN broadband network technology, xDSL broadband network technology, ATM asynchronous transfer mode, optical switching technology, and intelligent networks. Part 3 is dedicated to practical training content. Training projects are designed and developed to align with the applied nature of higher vocational education, such as operator console operation and system programming to provide practical skill training. Selected chapters in Part 1 include practice questions at the end. This book can serve as both a textbook and teaching reference for higher vocational colleges in electronic information-related fields, as well as a reference for telecommunications technicians.
