Increasingly, the use of fiber optic cable as a transport for voice, data, video, and Internet traffic is becoming the norm. SONET (Synchronous Optical Network) and SDH (Synchronous Digital Hierarchy) are being used with high-speed data transmission. Although SONET/SDH was originally intended for use in broadband ISDN and support leased line services like DS-1 and DS-3. SONET/SDH expansion is being fuelled by many of today's biggest industries such as Boeing, Disney and AT&T as these companies move their internal global networks to a SONET/SDH infrastructure. This work provides coverage of SONET/SDH technology written at a level that will be understandable to technicians working in the telecommunications industry. It includes detailed examples of DWDM (dense wavelength division multiplexing) and WDM (wavelength division multiplexing).

This text provides a crash course in the wireless Internet. WAP, SMS, i-mode, and Bluetooth are all compared and contrasted for their respective strengths and weaknesses, along with the existing and potential wireless markets. Other topics are mobile applications development languages and interoperability issues.

This work references some of the most commonly used and transported hazardous materials. Chemicals are conveniently listed alphabetically with the Reactivity Group Number (RGN).

This encyclopedia of wireless telecommunications provides concise articles for the generalist, with extended technical detail sidebars for developers. All of the technology terms are linked to markets and applications. It covers 2G, 5G and 3G technologies at all tiers from handsets to carriers.

This volume offers the reader advice on how to achieve new generation features with enhanced SONET and multi-lambda rings, compares SONET features and services with rival Ethernet-based offerings, and offers design approaches and business models for real-world deployment.

A job manual for the person in charge of the corporate network, explaining its operations and procedures. Topics include: vendor repair and return policies; calculating "true cost"; staff scheduling; system downsizing; asset identification; contingency planning; security tactics; and more.

MPLS is many things to many people. If you're moving IP voice traffic, it may mean performance gains for you. Daniel Minoli's "Voice Over MPLS" gives you the technical and business lowdown on innovative new solutions for packet-based voice. What does it take to build flexible, high-performance networks with enhanced quality of service? Maybe not as much as you think. Reliable voice services that customers can afford. With VoMPLS, you can deliver the quality associated with VoIP over ATM links without the cost in either bandwidth or equipment. Based on label-switching standards from the IETF and the work of a number of leading companies, "Voice over MPLS" lets you packetize voice without the added overhead of IP encapsulation. It also suppresses periods of silence, freeing up bandwidth for other uses.From one of the most experienced names in telecom technology, "Voice Over MPLS" shows you how to - provide multiple, high-quality services without costly leased lines; deliver low-bandwidth voice over ATM, Frame Relay, or IP; add phone "lines" without adding equipment; solve scaling issues for small- and medium-sized users; obtain consistent call quality without crunching bandwidth; discover ways to protect revenues during deployment; evaluate the potential role of VoMPLS in big-picture convergence; and evaluate VoMPLS's impact on public networks. Here, you find the engineering details you need for Label Switched Paths (LSPs), layers, signaling, CoS (Classes of Service), QoS (Quality of Service), VoMPLS in VPNs (Virtual Private Networks), implementation options, deployment, and more.

Because of their small, portable nature, PDAs present a unique security dilemma. This is the essential reference for PSA technicians and IT professionals who need to understand and solve this challenge. Written by a security expert, the book explores PDA security issues and details what must be done to establish privacy in the hand-held medium. It: covers the vast variety of devices available, including Palm, PocketPC, and RIM devices; includes foreword by Rebecca Bace, internationally recognized intrusion detection and network security specialist; includes a case study guide - "PDA Defense - Palm's Choice for Enterprise"; explains why handheld security is largely about OS (Operating Systems); explores hacking problems; answers the questions - when does a handheld become an IT problem and what is a measured IT response?
