...Chapter 2 NT1230 10/3/2014 1. When was the first major standard describing a structured cabling system released? c. 1995 2. What doe EIA and TIA stand for? i. EIA – Electronics Industries Alliance ii. TIA – Telecommunications Industry Association 3. What are the three parts of the EIA/TIA 568-B standard? i. EIA/TIA-568-B.1: Commercial Cabling Standard, Master Document ii. EIA/TIA-568-B.2: Twisted-pair Media iii. EIA/TIA-568-B.3: Optical Fiber Cabling Standard 4. Identify the six subsystems of a structured cabling system. i. Building Entrance (Also called (EF) Entrance Facilities) ii. Equipment Room (ER) iii. Telecommunications Closet (Also called (TR) Telecommunications Room or (TE) Telecommunications Enclosure) iv. Backbone Cabling v. Horizontal Cabling vi. Work Area 5. Which subsystem does permanent networking cabling within a building belong to? i. Backbone Cabling 6. What is a cross-connect? i. Cross-connect – A space where you are going to take one or multiple cables and connect them to one or more cables or equipment. 7. What is the main cross-connect? i. Main Cross-Connect (MC) – Usually connects two or more buildings and is typically the central telecommunications connection point for a campus or building. It is also called the Main Distribution Frame (MDF) or Main Equipment Room. The MC connects to telco, an ISP, and so...

...1. Application: Application is the term used within the Information Technology industry to reference software. The software can be for the end user which is known as the application software or it can be a Systems application software. 2. Unshielded twisted-pair: UTP, is also known as Category 5, and or Category 6. Consisting of 2 twisted pair of copper wire. UTP is the main type of cable used in LAN topography. 3. Shielded Twisted-Pair: Is similar to UTP, the main difference is that it is has an additional layer of shielding, this shield helps in preventing EMI, and other interference. STP is great application when a cable is being applied near power lines, metal pipes and is not in protected by plenum or conduit. 4. Fiber Optic Cable: Is a great long distance cable. There is Single mode, in which laser is transmitted and there is multimode, in which LED is transmitted. Both fiber cables are use to cover great distances up to allow data to traverse the fiber optic cable near the speed of light. 5. Dark Fiber is fiber optic cable is this idle and is not currently being used. 6. Coaxial Cable is an older cable that has a grounding copper core that is surrounded by a plastic protective insulating sheath, and then a protective grounding shield, and then there is the black outer protective plastic covering. 7. Plenum is a space or area that is intentional provided to allow for cables, pipes, tubing and other various plumbing. This space is typically...

...Physical Networking Unit 2 Assignment 1. The American National Standards Institute is a private non-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems, and personnel in the United States. The organization also coordinates U.S. standards with international standards so that American products can be used worldwide. For example, standards ensure that people who own cameras can find the film they need for that camera anywhere around the globe. ANSI accredits standards that are developed by representatives of standards developing organizations, government agencies, consumer groups, companies, and others. These standards ensure that the characteristics and performance of products are consistent, that people use the same definitions and terms, and that products are tested the same way. ANSI also accredits organizations that carry out product or personnel certification in accordance with requirements defined in international standards. 2. The Institute of Electrical and Electronics Engineers (IEEE, read I-Triple-E) is a non-profit professional association headquartered in New York City that is dedicated to advancing technological innovation and excellence. It has more than 400,000 members in more than 160 countries, about 51.4% of whom reside in the United States. IEEE is one of the leading standards-making organizations in the world. IEEE performs its standards making and maintaining functions through the...

...Fritz Dorcelus _ Physical Networking Cable Structure Week 3 assignment 1-What are the most common cables used today? Unshielded twisted-pair (UTP), shielded or screened twisted-pair (STP or ScTP), coaxial, and fiber-optic (FO) 2. Simply installing STP cabling does not guarantee that you will improve a cable’s immunity EMI or reduce the emissions from the cable. What are several critical conditions must be satisfied to achieve good shield performance? * The shield must be electrically continuous along the whole link. * All components in the link must be shielded. No UTP patch cords can be used. * The shield must fully enclose the pair, and the overall shield must fully enclose the core. Any gap in the shield covering is a source of EMI leakage. * The shield must be grounded at both ends of the link, and the building grounding system must conform to grounding standards (such as J-STD-607-A). 3. What are the distinct advantages of fiber optic? • Transmission distances are much greater than with copper cable. • Bandwidth is dramatically higher than with copper. • Fiber optic is not susceptible to outside EMI or crosstalk interference, nor does it generate EMI or crosstalk. • Fiber-optic cable is much more secure than copper cable because it is extremely difficult to monitor, “eavesdrop on,” or tap a fiber cable. 4. Cable bandwidth is a function of three interrelated, major elements. What are these major elements? Distance, Frequency, and Signal-level-to-noise-level...

...the members interested in developing a particular standard. b) ANSI standards include, SCSI interface specifications, programming language specifications, and specifications for character sets. c) ANSI helped to coordinate the efforts of the Electronic Industries Alliance (EIA) and the Telecommunications Industry Association (TIA) to develop ANSI/TIA/EIA-568, the cabling specification in the United States. 2) Electronic Industries Alliance (EIA) d) The Electronic Industries Alliance (EIA) was originally known as the Radio Manufacturers Association. Since then, the EIA has evolved into an organization that represents a wide variety of electronics manufacturers. e) The EIA is organized along specific product and market lines that allow each EIA sector to be responsive to its specific needs. These sectors include components, consumer electronics, electronic information, industrial electronics, government, and telecommunications. f) The EIA (along with the TIA) was the driving force behind the original ANSI/TIA/EIA-568 Commercial Building Telecommunications Cabling Standard. 3) Telecommunications Industry Association (TIA) g) The Telecommunications Industry Association (TIA) is a trade organization that consists of a membership of over 1,100 telecommunications and electronics companies. The TIA membership manufactures and distributes virtually all the telecommunication products used in the world today. h) TIA’s mission is...
