The Fiber Optics Illustrated Dictionary - Part 62 fills a gap in the literature by providing instructors, hobbyists, and top-level engineers with an accessible, current reference. From the author of the best-selling Telecommunications Illustrated Dictionary, this comprehensive reference includes fundamental physics, basic technical information for fiber splicing, installation, maintenance, and repair, and follow-up information for communications and other professionals using fiber optic components. Well-balanced, well-researched, and extensively cross-referenced, it also includes hundreds of photographs, charts, and diagrams that clarify the more complex ideas and put simpler ideas into their applications context | Fiber Optics Illustrated Dictionary LONTalk is powerful. Each node supports Network Management Services NMS such that they can respond to LONTalk commands from any node supporting NMS functions. Hierarchical addressing through domain subnet and node addresses can be used to interact with the network at any level. LONTalk can be implemented over a variety of types of media including twisted pair power line similar to X 10 radio links and coaxial or fiber optics cables. The LONTalk protocol can be implemented into microprocessors under the control networking standard by companies such as Echelon Corporation. See LONWORKS Neuron Chip. LONWORKS An internationally installed open network automation and control system for industrial and residential markets developed and trademarked by Echelon Corporation. LON stands for local operating network. The LONWORKS system uses intelligent control nodes intercommunicating with a common protocol called LONTalk. Each node includes embedded protocol and control functions and a physical interface for coupling the node controller to the communications medium. Nodes may be a variety of drives relays and sensing devices and may be used for automation production lines security and more. Local control nodes are the basic network devices for operational control and actuation. Supervisory nodes collect and log data from the local control nodes or coordinate their behavior. Routers provide connectivity and flow between LONWORKS network channels. The LONWORKS protocol can be embedded into processors from 8-bit microcontrollers to 32-bit microprocessors. The Neuron Chip is a low-cost commercially available processor with LONTalk support built in. In 1999 LONWORKS was approved as an open industry standard by the American National Standards Institute ANSI EIA -A-1999 Control Network Protocol Specification . The protocol is also approved by IEEE and other professional societies. Intelligent Technologies IEC is a significant .
