OSI IN THE VOICE ENVIRONMENT HERE’S STRAIGHTFORWARD EXPLANATIONS OF THE OSI LAYERS AND THEIR RELATIONSHIP TO TELECOM SERVICE AND EQUIPMENT. WHETHER YOU NEED ANWERS ON HARDWARE, SOFTWARE, ERROR CONTROL OR INTERFACES, LOOK INSIDE FOR BASIC FACTS AND HOW TO MANAGE THOSE CRITICAL “SPECIAL CIRCUMSTANCES” The OSI (Open System Interconnection) Reference Model is a cornerstone of modern network design. Although the OSI model has become almost synonymous with data communications, it serves the public switched telephone network (PSTN) as well and is a productive way to organize and teach the building blocks of telecom systems. In OSI Reference Model for Telecommunications, hands-on expert Debbra Wetteroth provides telecom staffers the information they need to gain a working knowledge of this essential telecom service architecture and equipment. Her style that breaks down the barriers between data and voice vocabularies. This quick reference to the OSI model puts the data you need everyday at your fingertips. Look inside for an understandable schematics of: * Mapping PSTN functions to OSI * The basics of successful data transmissions * What OSI is and does * The components that make up OSI * OSI “common knowledge” (the kind that’s not always so common), such as numbering system, signaling rates, and noise distortion data * A detailed description of Layers 1 to 3 and a thorough review of the Transport Layer. For each layer, you’ll learn roles, functions, definitions, and more This unique volume will prove invaluable to telecommunications technicians, field supervisors, switch managers, network analysts, network designers, and anyone else who needs detailed explanation of the many components of OSI.

IP (internet protocol) Telephony, enabled by softswitches, isgoing to usher in a new era in telecommunications. By putting voiceand data over one IP network, operators can enjoy lower costs andcreate new, revenue-generating "multimedia" services. This valuable reference offers a comprehensive overview of thetechnology behind IP telephony and offers essential information tonetwork engineers, designers and managers who need to understandthe protocols and explore the issues involved in migrating theexisting telephony infrastructure to an IP-based real timecommunication service. Drawing on extensive research and practical developmentexperience in VoIP from its earliest stages, the authors giveaccess to all the relevant standards and cutting-edge techniques ina single resource. IP Telephony: Deploying Voice-over-IP Protocols: Assumes a working knowledge of IP and networking and addressesthe technical aspects of real-time communication over IP. Presents a high level overview of packet media transporttechnologies, covering all the major VoIP protocols – SIP,H323 and MGCP Details specific strategies to design services for publicnetworks where endpoints cannot be trusted and can be behindfirewalls. Explores the problems that may arise from incomplete protocolimplementations, or architectures optimized for private networkswhich fail in a public environment. This amply illustrated, state-of-the art reference tool will bean invaluable resource for all those involved in the practicaldeployment of VoIP technology.

Annotation Demystifying the operation of Intenet telephone protocols and technologies, IP Telephony, by Walter Goralski and Matthew Kolon, establishes a solid framework for Internet-powered voice communications. This quick-study reference explains the world of central office switches and signaling protocols, exploring every phase of telephony from billing to caller ID to voice routing protocols. Conversely, it explores the existing structure of the Internet and the IP protocol stack to explain the world of routers and connectionless IP. You'll find a bonanza of examples that demonstrate how organizations; local, national and global can employ Internet telephony both to save money and to provide services ranging from Internet faxing to solving a multitude of business problems. This plain-English guide lets you.*See how to make your existing data network do double duty as your phone system*Explore voice-enabled Web sites for everything from Internet telemarketing to customer support*Understand the implementation standards, SS7, H.323, RSVP, the ITU G.x series, and more*Recognize the role of Internet telephone gateways*Understand the relationship between quality of service (QOS), frame relay, and ATM network as voice vehicles*And much more.

All you need to know about deploying VoIP protocols in one comprehensive and highly practical reference - Now updated with coverage on SIP and the IMS infrastructure This book provides a comprehensive and practical overview of the technology behind Internet Telephony (IP), providing essential information to Network Engineers, Designers, and Managers who need to understand the protocols. Furthermore, the author explores the issues involved in the migration of existing telephony infrastructure to an IP - based real time communication service. Assuming a working knowledge of IP and networking, it addresses the technical aspects of real-time applications over IP. Drawing on his extensive research and practical development experience in VoIP from its earliest stages, the author provides an accessible reference to all the relevant standards and cutting-edge techniques in a single resource. Key Features: Updated with a chapter on SIP and the IMS infrastructure Covers ALL the major VoIP protocols – SIP, H323 and MGCP Includes a large section on practical deployment issues gleaned from the authors’ own experience Chapter on the rationale for IP telephony and description of the technical and business drivers for transitioning to all IP networks This book will be a valuable guide for professional network engineers, designers and managers, decision makers and project managers overseeing VoIP implementations, market analysts, and consultants. Advanced undergraduate and graduate students undertaking data/voice/multimedia communications courses will also find this book of interest. Olivier Hersent founded NetCentrex, a leading provider of VoIP infrastructure for service providers, then became CTO of Comverse after the acquisition of NetCentrex. He now manages Actility, provider of IMS based M2M and smartgrid infrastructure and applications.

Tehrani's IP Telephony Dictionary -2nd Edition, The Leading VoIP and Internet Telephony Resource provides over 11,000 of the latest IP Telephony terms and more than 450 illustrations to define and explain latest voice over data network (VoIP) technologies and services. It provides the references needed to communicate with others in the communication industry where many new terms and concepts are being added each day. It includes directories of magazines, associations and other essential trade resources to help industry professionals find the information they need to succeed in this rapidly growing industry. To ensure this dictionary contains the latest definitions, a senior editor, a panel of 15 experts, and more than 1,025 industry reviewers added, validated, and edited definitions. This book is an essential reference book for those involved in all aspects of the Internet and voice over data network (VoIP) industry.

This book presents end-to-end system basics for IP telephony—the technology that enables private data networks to provide extended communication services and multimedia transmission over standard phone lines. Written by the chief architects of H.323, the governing protocol for IP telephony, this book delivers the most authoritative coverage of what is considered the hottest topic in networking today. Network and telecommunications professionals will find clear discussions of the principles and implementations of next generation architectures and services, as well as comprehensive coverage of the related protocols, addressing and routing issues, interworking IP with legacy systems, deploying gateways, and more. Mobility, security, and QoS aspects of H.323 systems are also explained in detail.
