Introduction to Public Switched Telephone Networks, POTS, ISDN, DLC, DSL, and PON Technologies, Systems and Services, 2nd Edition Summary
| Public telephone networks are unrestricted dialing telephone networks that are available for public use to interconnect communications devices. This book describes the fundamentals of analog and digital telephone technology and communication and how the different types of analog and digital audio signals are described along with how their forms (PCM coding) differ in various parts of the world. You will learn about plain old telephone service (POTS) analog lines and integrated services digital network (ISDN) lines. The efficient GR-303 digital loop carrier (DLC) system is described along with how remote digital terminal (RDT) can allow a single communication line to provide telephone service for many businesses and homes. You will also learn how passive optical networks (PONs) are being used to deliver high capacity fiber optic communication to the premises (FTTP) communication lines direct to customers locations. The different types of switching systems are explained from circuit switched crossbar and time slot interchange (TSI) switches to packet voice and soft switches. You will learn how switches are interconnected with each other to form a global public telephone system. Multi-channel trunked lines are described including digital signaling (DS) lines, synchronous optical lines, and multi-channel optical (WDM) lines. You will learn how customers may lease lines or portions of communication lines for their own specific purposes. This book describes how telephone systems are controlled using signaling control messages, call processing, and SCP databases. You will learn about the different types of in-band tone signaling and of band common channel signaling system 7 (SS7). Also covered is how the public switched telephone network (PSTN) is beginning to use advanced intelligent network (AIN) to provide for advanced telephone service features. Explained are the key types of telephone voice, data, video and Centrex services. You will learn how customer care syste... |
