Signaling In Telecommunication Networks Second Edition is the updated version of the highly acclaimed book first released in 1997. It has been enhanced to cover the most recent developments in signaling systems and procedures. It covers both subscriber and network signaling in both fixed as well as mobile networks.

The book is divided into 22 chapters that begin with an introduction to telecommunications and a broad overview of communication networks and how telecommunications systems work. The next 18 chapters are devoted to what this book is about; signaling in communications networks in the traditional sense with circuit-switched networks. The last three chapter cover packet networks with the focus on convergence of voice and data.

Coverage begins with an introduction to circuit-switched telephone networks, including an examination of trunks, exchanges, access systems, transmission systems, and other basic components. Next, the authors introduce signaling concepts, beginning with older Channel Associated Signaling (CAS) systems and progressing to today's Common Channel Signaling (CCS) systems. The book then examines packet networks and their use in transmitting voice (VoIP), TCP/IP protocols, VoIP signaling protocols, and ATM protocols.

In the past ten years, new technologies have come in to use and hence there are now new as well as expanded signaling systems available. To this end Signaling In Telecommunication Networks Second Edition has added six new chapters.

Chapter eight examines how "Access Systems" have become part of the local network architecture. How such systems, once called remote line concentrators, which use to have proprietary interfaces, now have become standardized.

Chapter 13 explores how in code-division multiple access wireless systems, originally developed for the military because of it's superior anti-jamming and anti-eavesdropping characteristics is now being use for the civilian market. It has now become the technology of choice for third generations of wireless systems worldwide.

Chapter 18 covers Intelligent Network Application Part (INAP) which is the ITU-T standard protocol used for communications between application entities in an intelligent network. The authors explain about the four different planes and how they relate to the four different ways of looking at an intelligent networks and services.
