PREFACE TO THESECOND EDITIONThe first edition of this book covered signaling for telecommunications through theearly 1990s. Telecommunication technology has continued its remarkable progressin the years that followed. New technologies and services have come into use, andare supported by a number of new or expanded signaling systems. The aim of thissecond edition is to cover some of the most important of these new technologiesand their signaling. Six new chapters, briefly outlined below, have been added forthat purpose.Access systems (Chapter 8) have become a part of the local network architecture.Several access systems (AS) surround a local exchange, each one serving the analogand digital lines of a group of nearby subscribers. Such systems, once called ‘remoteline concentrators’, used to have proprietary interfaces to the local exchanges. Interfacesand signaling have now been standardized, allowing a telecom to purchaseaccess and switching hardware equipment from different product suppliers.In code-division multiple access (CDMA) wireless systems (Chapter 13) alltraffic channels in a cell are carried in two common (forward and reverse) frequencychannels. Individual traffic channels can be separated because the data stream fromthe user is encoded at the sending end with a special bit sequence that identifies thechannel. To recover this information, the receiving end decodes the sender’s datastream with the same sequence. Regardless of the number of cells, a CDMAsystem thus needs only one pair of frequency bands. This is an important advantageover AMPS and TDMA systems, which manage interference by assigning differentRF bands (up to seven pairs) to adjacent cells.INAP (Chapter 18) is the ITU-T-sponsored architecture and protocol for remoteoperations, equivalent to, but much more ambitious and complex than, theAdvanced Intelligent Network described in Chapter 17. INAP standards are basedon a sophisticated multi-level abstract view of features and services.The first edition of this book did not cover networks for data communication,which made their appearance around the 1970s. Data communicationxiii
xivPREFACE TO THE SECOND EDITION(Chapter 20) has expanded tremendously over the last 30 years, reflecting the enormousincrease in the availability of computers and in the number of applications thatrequire distributed data processing. A data message consists of a sequence of‘packets’, short data bursts that have two parts: the ‘header’, which contains signalinginformation used by intermediate nodes to route the packet to its destination, anda second part that carries user information. Among the most important innovationsin communications is the convergence of voice and data in packet networks, popularlyknown as Voice over IP (VoIP). The door to convergence was opened in the1960s with the introduction of digital voice transmission. Digitally coded speechcan be transported in a data network as a sequence of packets, each one carryinga number of speech samples. This technology is revolutionizing telecommunicationsand the driving factors for that are discussed in Chapter 20.The most popular and widely deployed signaling protocols for VoIP, such asH.323, SIP, H.248, and BICC are discussed in Chapter 21.ATM, or asynchronous transfer mode (Chapter 22), closes the book with a discussionof a packet technology that supports broadband multimedia communication,and facilitates the interworking of packet-switched and circuit- switched networks.Although widely deployed in carrier backbone networks and in ADSL access networks,ATM appears to have lost momentum to packet technology based onTCP/IP protocols.Chapters 11 (ISUP), 14 (Introduction to Transactions), and 16 (TCAP) have beenrewritten to cover the newest developments in ITU-T standards. Chapters 1 through7 have also been updated to reflect current standards.We would like to extend our grateful thanks to former colleagues from LucentTechnologies who were invaluable in providing advice and information, as wellas in reviewing parts of the manuscript: Donald W Brown, James R Davis,Thomas S Hornbach, Konstantin Livanos, Alan J. Mindlin, Leon J Peeters, andMakoto Yoshida.We cannot close this preface without also thanking our wives, Maria and Elizabeth,without whose patience, understanding, and loving support this second editioncould not have been written.
