Networking ch. 2 pt 1

TIA/EIA-568 Commercial Building Wiring standard or structured cabling describes what?

Uniform, enterprise wide cabling systems regardless of who the manufacturers are or sells the various parts used in the system.(also the best way to install network media to maximize performance and minimize upkeep.)(Principles of structured cabling apply no matter what type of media or networking speeds are involved, and uses hierarchical star topology.)

.cables or wireless links that provide interconnection between the entrance facility, mdf, and between mdf and idf?

Backbone cabling

Radius of the maximum arc you can loop a cable without impairing data?

Bend radius( usually 4x diameter of cable in twisted pair)

Difference between fiber optic and copper cabling?

Copper transmits data with electric signals and fiber optic uses pulsing light from a laser or led.

Data closet or equipment room or telecommunications room that is an enclosed space that holds network equipment that may have requirements like cool temps?

Data Room.

Main components for a network?

Demarc, MDF and IDF's.

Things to remember about termination?

Don't leave more than 1 inch exposed when terminating twisted pair to avoid interference of transmission between lines(crosstalk).

Location where incoming network like internet connects with school or corporate network that can be an equipment room or cabling on a building, where telecommunications service provider(ISP/or local) accepts responsibility for the external connection, has providers equipment and protective boxes, and has the most important piece, the demarc?

Entrance facility.(network begins at demarc and ends at work station).

Things to consider about racks?

Height(42U tall=6 feet, or half racks 18u-22u), width(19-23 inches) and depth.

Cabling that connects workstations to the closest data room and to switches houses in the room (maximum of 100m long), up to 90m for connecting network device in data room to data jack in work area wall, and up to 10m to connect wall jack to work station?

Horizontal Cabling.

In typical rack system chassis, air moves from front to back but in data centers with multiple rows of racks what is the system?

Hot aisle/cold aisle layout pulls cool air from vents into the rows of the racks and hot air aisles are used to direct heated air away from racks into exhaust vents for cooling.)(hot air pumped out cool air pumped in).

How to avoid electromagnetic interference(EMI)?

Install cable at least 3 feet away form fluorescent light sources including tv, power lines, sources of electricity motors etc.(avoids noise and interference of signals).

Provides an intermediate connection between MDF and end user equipment on each floor in each building that can be racks holding network or room for both racks and equipment, can be many of these per user that are connected to internal network, must be one per floor according to TIA EIA, connections branch out to workstations in extended star topology?

Intermediate Distribution frame(IDF).

Racks have one______ that connects all devices on rack to console?

KVM(keyboard video and mouse switches).

Tips for managing cabling documentation?

Keep things centrally accessible and make sure it has locations, install dates, lengths and grades, label every data jack or puch panel or punchdown block or connector/circuit,use color coded cables for different purposes update things.

Main cross connect that is the centralized point of interconnection for an organizations LAN or WAN, can refer to racks holding up network equipment or room that houses racks, can be in same room as entrance facility?

MDF(Main distribution frame/facility)(has ethernet cables, idf cables and incoming connection from provider,).

Often houses an orgs main servers, is a connection for cables, might have a demarc, transreceiver for signal conversion from isp to ethernet, switches, and transmission media like fiber optic?

Main Distribution Frame (MDF).(one per user)

Helps verify each segment of cabling transmits data reliably?

Verify continuity with cable tester(prevents testing long stretches of cable)

Panel of voice or data receptors that has twisted pair wire or wire that is punched down to complete a circuit?

Punchdown block (110 is for data connections and 66 is used for phones, 1110 is not to be twisted more than one half inch and is newer).

A large data center that can contain rows of racks to hold various network equipment and makes good use of space to ensure adequate access and ventilation?

Racks

Increasing humidity is caused by?

Rising levels of water in the air that can damage sensitive electronic equipment

Components of backbone cabling?

Vertical cross connect that runs between buildings floors.(often made in thick fiber optic cabling.

Often connected by VoIP PX's that might be telephones sitting at each users location or apps hosted on a user's computer or other device?

VoIP Endpoints.

Converts signals from a campus analog phone equipment into IP data that can travel over the internet or converts VoIP data from an internal IP network to travel over a phone company's analog telephone line?

VoIP Gateway

Dedicated telephone or switch or a virtual switching device that connects and manages calls within a private organization and manages call connections that exit the network through a voIP gateway?

VoIP PBx(Private Branch exchange).

IP telephony that is the use of any network(public/private) to carry voice signals using TCP/IP Protocols?

Voice over IP

Must contain at least one voice and one data outlet?

Wall Jacks( for TIA/EIA outlets voice hole is small and on top and data hole is big and on the bottom).

Areas for workstations printers and network devices and allpatch cables, wall jacks and horizontal cabling necessary to connect these devices to a data room?

Work area.

Organization that has a single cabling standard most companies follow?

Telecommunications Industry Association, and Electronic Industries alliance.

Come is 2, 4 and sometimes 6 post racks that can be open for great accessibility or closed for protection, have side posts for bracketing and attaching devices like routers and switches that come with rack ears to secure attachment?

racks(post hoels can be square or threaded or non threaded, square is most recent with bolt free mounting).(wall or ceiling mounted or freestanding or bolted to the floor)

Panel of data receptors that can be mounted to a wall or a rack and provide a central termination point when many patch cables converge on a single location?

Patch Panel.

Relatively short (3-25) feet length of cabling with connectors at both ends?

Patch cabling

Used to organize and connect lines and does nothing to the data transmitted on a line other than pass the data along through the connections, run from walls to racks to network devices and make it easy to switch out things?

Patch panels'

Structured cabling installation types?

Patch, horizontal and backbone cabling?

Coated with flame resistant jacket that produces less smoke than regular cable with polyvinyl chloride, requires you to check with electric installation codes if you run it above ceiling tile or below subflooring?

Plenum rated cabling.

3 cabling types for horizontal cabling?

UTP(copper with 1 or more twisted wires encased in plastic sheath), STP(copper with twisted wire that's individually insulated and surrounded by shielding made of metallic substance like foi) or fiber optic cable(has one osr several glass or plastic fibers in core & has two types single or multimode fiber)

Place where providers network ends and users begins?

demarc(ISp responsible for network beyond demarc and user is responsible for the other side of demarc.
