Telecommunications Engineer's Reference Book


Book Description

Telecommunications Engineer's Reference Book maintains a balance between developments and established technology in telecommunications. This book consists of four parts. Part 1 introduces mathematical techniques that are required for the analysis of telecommunication systems. The physical environment of telecommunications and basic principles such as the teletraffic theory, electromagnetic waves, optics and vision, ionosphere and troposphere, and signals and noise are described in Part 2. Part 3 covers the political and regulatory environment of the telecommunications industry, telecommunication standards, open system interconnect reference model, multiple access techniques, and network management. The last part deliberates telecommunication applications that includes synchronous digital hierarchy, asynchronous transfer mode, integrated services digital network, switching systems, centrex, and call management. This publication is intended for practicing engineers, and as a supplementary text for undergraduate courses in telecommunications.

Federal Bureau of Investigation's Management of Confidential Case Funds and Telecommunication Costs


Book Description

The FBI conducts undercover activities as part of its mission to detect & deter terrorist attacks & foreign intelligence threats & to enforce U.S. The FBI uses confidential funds to support its undercover activities. There was a criminal investigation into allegations that an FBI employee stole FBI confidential case funds. As a result of this investigation, in June 2006 a telecomm. specialist at an FBI field division pled guilty to stealing over $25,000 in confidential case funds intended for undercover telecomm. services. This audit evaluates how the FBI & its field divisions: (2) request & track confidential case fund payments; (2) handle telecomm. expenses that support undercover activities; & (3) control & oversee the confidential case funding process.










Telecommunications


Book Description

Explains how selected states have encouraged private investment in advanced telecommunications; how these states have encouraged widespread access; and what lessons their experiences could provide for others. Focuses on the selected states that have started developing their telecommunications infrastructure. Seventeen charts, tables, and graphs.




Impact of Distributed Energy Resources on the Reliability of a Critical Telecommunications Facility


Book Description

Documents a probabilistic risk assessment of an existing power supply system at a large telecomm. office. The focus is on characterizing the increase in the reliability of power supply through the use of two alternative power configurations. Failures in the power systems supporting major telecomm. service nodes are a main contributor to major telecomm. outages. A logical approach to improve the robustness of telecomm. facilities would be to increase the depth and breadth of technologies available to restore power in the face of power outages. Distributed energy resources such as fuel cells and gas turbines could provide one more onsite electric power source to provide backup power, if batteries and diesel generators fail. Illustrations.
