Here are some more paragraphs based on the textbook:
Chapter 1 introduces the basic concepts and terminology of digital telephony, such as analog and digital signals, sampling, quantization, coding, modulation, multiplexing, switching, and transmission. It also explains the advantages and disadvantages of digital telephony over analog telephony, such as improved quality, efficiency, security, and flexibility.
Chapter 2 discusses the structure and operation of the public switched telephone network (PSTN), which is the global system of interconnected telephone networks that provide voice and data services to users. It describes the components and functions of the PSTN, such as local loops, trunks, switches, signaling systems, and network management. It also reviews the evolution and trends of the PSTN, such as the transition from circuit-switched to packet-switched networks, the integration of voice and data networks, and the emergence of new services and applications.
Chapter 3 focuses on the transmission aspects of digital telephony, such as the characteristics and impairments of transmission media, the methods and standards for transmitting digital signals over various media, and the techniques for measuring and improving transmission quality. It covers topics such as twisted-pair wires, coaxial cables, optical fibers, radio waves, pulse code modulation (PCM), time division multiplexing (TDM), line coding, error control coding, synchronization, equalization, echo cancellation, and performance evaluation. 0efd9a6b88
