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.
