ABSTRACT: This release in the Notes on...series, Telcordia Notes on SS7 and CCS Network Evolution, discusses the ongoing evolution of the
Signaling System 7 (SS7) protocol and wireline Common Channel Signaling (CCS) network architectures. This document provides high-level
information on the currently deployed and evolving SS7 protocol and carrier CCS networks, recent developments, and future directions.
With Telcordia Notes on SS7 and CCS Network Evolution, you will learn about:
- The history of the SS7 protocol and CCS, the network architectures, and deployments
- The status of recent SS7 standards related to protocol and network capabilities, and activities related to deployments of such
capabilities, with an emphasis on Local Exchange Carrier (LEC) CCS networks in North America
- Current industry directions for the ongoing evolution of SS7-based signaling and control as carrier networks begin to evolve beyond
conventional circuit-switching and dedicated Time-Division Multiplexed (TDM) link and circuit facilities toward distributed Voice Over
Packet (VoP) architectures based on Asynchronous Transfer Mode (ATM) and/or Internet Protocol (IP) data transport technologies.
- The interworking capabilities of the evolving SS7 protocols with the new IP-centric protocols, such as the Session Initiation
With the Notes on...series, Telcordia Technologies has devised a starting point for your search through the rapidly developing world of
telecommunications. Written by the authors of the successful Telcordia Notes on the Networks document SR-2275, this series
similarly contains technical material of interest to engineering and planning groups, as well as descriptions of the characteristics
and background of these subjects in layman's terms. The difference is that Telcordia Notes on...zeroes in on one technology in each
document and breaks it down into manageable terms. From the history, background, and basic elements through a discussion of what the
future may bring, our subject matter experts cover the important aspects in as few words as possible.
