Features: This textbook focuses on introducing programmable digital switching related to telephone exchange services, primarily aimed at readers with limited theoretical understanding of communication technology. It does not reach a depth that allows readers to design programmable switching equipment, but instead equips readers with fundamental knowledge for engineering practices such as assembly, operation, access, maintenance, and management through learning. It also provides a simple overview of new services in current switching technology. The book introduces the basic concepts and working principles of programmable switching systems, as well as an overview of the maintenance and management methods for programmable digital switches. The book consists of 8 chapters, covering the main content including: the development and basic structure of programmable digital switches; the basic principles of pulse code modulation (PCM) and error control technology; the basic principles of call processing; the basic composition of digital switching networks; the construction and principles of CC08 programmable digital switches; the concepts and construction principles of user line signaling, inter-exchange signaling, and common channel signaling systems; the engineering design and maintenance management methods for programmable private branch exchanges (PBX); the characteristics and development prospects of modern programmable switching technology. This book is suitable for students of communication and electronic engineering majors in vocational and technical colleges, and can also serve as a training textbook and reference for communication engineering technicians.
