IntroductionIntroductionMany network administrator keep hearingthat the network is down because of someor the other reasons. Various researchesindicates that in many cases, the network isdown because of inferior cabling system
IntroductionIntroductionStructured cabling divides the entireinfrastructure into manageable blocks andthen attempts to integrate these blocks toproduce the high-performance networksthat we have now come to rely on. To theuser, this means investment protection
WHAT IS STUCTURED CABLINGWHAT IS STUCTURED CABLINGStructured cabling is an architecture forcommunications cabling that is specified bythe TIA/EIA. It includes communicationscabling from the point where it enters abuilding, through the equipment andtelecommunications rooms, and up to thepoint where it connects to equipment in thework area. This system supports high speedvoice and data networks.
What is the TIA/EIA?What is the TIA/EIA? TIA/EIA stands for "TelecommunicationsIndustry Association / Electronic IndustriesAlliance." The TIA/EIA is an industry tradeassociation that creates interoperability standardsfor the products made by member companies,including the standards for structured cablingsystems. Following TIA/EIA standards ensuresthat the parts of a structured cabling system willbe compatible and allows for ease of moves, adds,and changes

An equipmentroom is the areawhere incomingbackbone cablinginterfaces withelectronicequipment, such asa telephone switchand/or wide areanetwork (WAN)hardware. It is alsothe cross-connectpoint to theoutgoing backbonecabling.
The backbonecabling is the maintrunk or feeder forthe horizontalcabling that isbrought into thetelecommunicationsroom. It consists ofthe cable andmechanicalterminations forbackbone-to-backbone cross-connects.
A telecommunicationsroom is the area withina building that housesthetelecommunications /networkingequipment, as well asthe connectionsbetween backbone andhorizontal cabling.
As its name implies,the horizontal cablingruns in a horizontaldirection. It extendsbetween thetelecommunicationsroom and the workarea. It includes thecable, work areaoutlet, and any cross-connect (patch) cords.
How is structured cabling used?How is structured cabling used? Structured cabling is sometimes referred to as"low voltage" or "data/voice" cabling. It serves asthe infrastructure for telephone and local areanetwork (LAN) connections in commercialbuildings. It carries voice and data to work areaequipment such as telephones, fax machines, andcomputers. It can also carry video for applicationssuch as teleconferencing. The efficient flow ofinformation is vital to the success of todaysorganizations, and users have come to expect thesame reliability from networks as they do fromutilities such as electric, gas and phone service.
Advantages of Structured CablingAdvantages of Structured Cabling • Consistency - A structured cabling systems means the same cablingsystems for Data, voice and video. • Support for multi-vendor equipment - A standard-based cablesystem will support applications and hardware even with mix &match vendors. • Simplify moves/adds/changes - Structured cabling systems cansupport any changes withinthe systems. • Simplify troubleshooting - With structured cabling systems,problems are less likely to down the entire network, easier to isolateand easier to fix. • Support for future applications - Structured cabling systemsupports future applications likemultimedia, video conferencing etc with little or no upgrade pain.
Advantages of Structured CablingAdvantages of Structured CablingAnother primary advantage of structuredcabling is fault isolation. By dividing theentire infrastructure into simplemanageable blocks, it is easy to test andisolate the specific points of fault andcorrectthem with minimal disturbance to thenetwork. A structured approach in cablinghelps reducemaintenance costs too.
What Types of Equipment CanWhat Types of Equipment CanUse Structured Cabling?Use Structured Cabling?Structured cabling can provide for yourcurrent and future needs for electronicsystems.Installing a wiring system as you build yournew home or office is only a fraction of thecost of retrofitting it later. Plan ahead.Before hanging the first sheet of drywall,consider the electronics youll want in yournew business or home

Why Use Structured Cabling?Why Use Structured Cabling? Consistency - A structured cabling system can use thesame cabling system for everything. Do you really want tofigure out how to install and troubleshoot the phonecabling, then figure out the ethernet cabling, then figureout the ISDN cabling...? What happens when you revisitthis in 6 months to make a change for two-line phones? Long life - Structured cabling is an investment that willlast for the long term. Support for multi-vendor equipment - A standards-basedstructured cabling system will support your applicationsand hardware even after you change or mix & matchvendors. With the proper structured cabling system youwill not have to rework the cabling when you upgrade toanother vendor or model.

Why Use Structured Cabling?Why Use Structured Cabling? Simplify moves/adds/changes - Need to move a computeror TV from one room to another. Add a modem connectionto the office. Add a two-line phone, DSL, AND fax to theoffice. Share files or printers between computers. Simplify troubleshooting - Even cables that were installedcorrectly can fail -- and they do. With a structured wiringsystem, problems are less likely to down the entirenetwork, easier to isolate, and easier to fix. Support for future applications - Your structured cablingsystem will support future applications like multimedia,video conferencing, and who knows what else, with little orno upgrade pain

Structured Wiring vs. Conventional WiringStructured Wiring vs. Conventional Wiring Think of wiring as a pipeline for information.Conventional wiring has the data capacity of a squirt gun.By comparison, structured wiring, using Category 5cables, has the capacity of a fire hose. Structured wiringcan transmit more information, faster. Conventional wiring, which is found in most homes,consists of one or two twisted pairs of wires, and isadequate for basic voice, fax or data communications. Structured wiring is more advanced wiring. Not only can ithandle traditional telephone, fax and datacommunications, but also sophisticated video and datasignals from computers.
