(This book is the material I read in the past two years. It was sent during training. I have seen similar ones on the Internet, but the scan is rough and the color is cast. This attachment is the electronic version of the book, not a copycat version downloaded from the Internet. Shared with everyone, I hope it will be effective for everyone: Chapter 1 Introduction to Integrated Cabling; Chapter 2 Design of Integrated Cabling System Chapter 3 System Engineering Testing and Acceptance Appendix Part I: Project Bidding Part II: Project Overview (Budget) Part 3: Supervision of Integrated Wiring Projects Part 4: Postscript Back Cover of Integrated Wiring System Project Implementation)
