9. The main design standard applies worldwide is ISO 11801-2nd Edition
10. The main design standard for Canada is the CAN / CSA T529
11. The main design standard for Australia / New Zealand is the AS / NZS
3080
12. The main design standard for the United States is the ANSI / TIA / EIA 568 - B.1
13. relevant standards are written by CENELEC
(European Committee for Electrotechnical Standardization) and the standard for the
Structured cabling is he EN 50173. The CENELEC standards are
Numbered and start in at "European Standard (European Norm)." As
General, there are many other standards that refer to the primary standard. By
Example, the set of standards that might affect an important project
Wiring a campus in the United States rapidly expands
Incorporate the requirements of routes and areas of construction,
Administration and electricity:
TIA/EIA-568-B: Standard wiring. This standard specifies
Transmission requirements and components for media.
TIA/EIA-569-A: Tours and cable spaces.
TIA/EIA-570-A: retail commercial and residential wiring.
TIA/EIA-606: Standard Management including labeling
Cables on the ground.
TIA/EIA-607: Requirements for earthing and connection.
14. which are the standards: allow you to install a generic structured cabling plant to be able to run any voice application or data scheduled for the next ten to fifteen years.
15. is EF, Entrance Facility: the
The point at which the
Cables outside the building through the wall or go to the basement. In some
Cases, the EF is shared with the facilities of income from other services. In other cases, there is a room or a panel for the EF.
Both the ISO and the ANSI / TIA / EIA require
Outside plant cables for telecommunications are
Connected to a few meters from the entrance. Usually this is because the composition of such cables is not eligible for limiting smoke and fire to be met by internal wiring. If burned, the components of filler used to keep the cables free of moisture and without backbone
Other contaminants can be dangerous.
16. which is the TIA/EIA-569-A specifies standards for space
From the point of demarcation. Standards regarding the size and structure
The demarcation point space are based on the size of the building.
For buildings over 2,000 usable square feet (21 528 feet
square), we recommend you have a room inside the building
Specially designated for that purpose and having key.
17. wiring density is: Refers to the number of cables that come in a telecommunications room. Even a small telecommunications room may
Having a high wiring density if it works in an area with many
Network devices. Whenever possible, the size of a TR must
Adjusting to the wiring density of the area in which it operates. The type of
Termination used in the room also can affect the number of wires that can be handled in a given space
18. which is a direct connection: Both ends of the cable must be armed in the same way when looking for drivers. In 10BASE-T Ethernet or 100BASE-TX only uses four wires:
1. Determine the distance between devices, or device and the connector, then add at least 30 cm. The maximum length for this cable is 3 m. The standard lengths are 1.82 and 3 m.
2. Cut a piece of twisted pair Cat 5 unshielded long established. Stranded cable used for connecting cables as it has a more durable when bent repeatedly. Solid wire is perfect for cable runs that are punched down into jacks.
3. Remove 5 cm wrap one end of the cable.
4. Keep tightly together four pairs of twisted wires to which the sheath was removed after the cable pairs rearrange the order of the standard 568-B wiring. Try to keep the braids as this is what provides noise cancellation. (Orange pair, green pair, blue pair, brown pair)
5. Hold the jacket and cable in one hand, Untwist a small stretch of green and blue pairs reorganícelos so as to meet the color wiring diagram 568-B. Untwist and order the rest of the wire pairs according to the color scheme.
6. Flatten, straighten and align the wires, then prune them in a straight line around 1.20 cm - 1.90 cm from the edge of the envelope. Be sure not to drop the jacket and the wires that are now sorted! Should minimize the length of untwisted wires because sections too long connectors located near a major source of electrical noise.
7. Place an RJ-45 cable end with the tab down and the orange pair on the left side of the connector.
8. Gently push the wires into the connector until you can see the copper ends of the wires through the connector end. Make sure the end of the jacket is inside the connector and that all wires are in the correct order. If the jacket is not inside the connector will not be properly protected from the pulls and eventually cause problems. If everything is correct, crimp the connector with sufficient force to force the contacts through the insulation on the wires, thereby completing the conductive path.
9. Repeat steps 3-8 to complete the other end, using the same diagram to complete the direct connection cable (straight-through).
VERIFICATION OF DIRECT CONNECTION CABLE:
First check the cable using as reference the diagram that shows the colors of the wires. After having visually checked the cable, use the multimeter to check the continuity (resistance) of each cable circuits. First press the button with the Ohms (red) to select measures of continuity. Check continuity of each of the circuits (pairs) of the newly built cable ..

23. metal racks which are: Distribution System in treated plywood panels. At least two walls should be covered with 20 mm (0.8 in.) AC plywood, which is at least 2.4 m (7.9 feet) tall. The "A" in the grading system for AC Plywood indicates the side that should be in front. This is the side of the plywood with the best. If the telecommunications room functions as the main hall of the building, then the point of presence (POP) phone, or demarcation point can also be located within the room. In this case, the interior walls demarcate behind the PBX, should be covered from floor to ceiling with 20 mm (0.8 inch) plywood. It must provide a minimum of 4.6 m (15.1 feet) of wall space for connections and related equipment.
24.
25. The equipment must be placed carefully on racks for equipment. Considerations include whether or not to use electrical equipment, the installation and cable management and ease of use. For example, a connection panel should not be placed on top of a frame if you're going to make significant changes after the installation of the systems. Another important consideration is the planning of the provision of facilities

31. What is IEEE: Institute of Electrical and Electronics Engineering (institute of electrical and electronics enginneers)
32. is multimode: Fiber optics is a transmission medium commonly used in data networks, a very fine thread of a transparent material, glass or plastics, which are sent light pulses that represent the data to be transmitted. The light beam is completely confined and is spread through the fiber core at an angle of reflection above the critical angle of total reflection, according to Snell's law. The light source may be laser or LED.
33. which is a transpuerto cable: see cable reel is used as the console cable to connect a PC to a roster or switches via the console port. One end of the cable as will tend to the wiring diagram 568-B or A, while the other end by pin pin is reversed. Pin 1 on one end is Pin 8 of the other, the two will be on 7 and so on until everyone is invested. In the phone straight cable, this is achieved by ensuring that the connectors 8P8C Locks appear on the same side of the cable (using cable Union as reference).
34. which is a campus distributor (CD), or Main Cross-Connect (MC) is the main rallying point of a campus or entire building. The MC is actually the telecommunications room (TR) rates. This is the room that controls the rest of the TR (the IC and HC) of a building or campus. It is the central point of the star topology (discussed in Chapter Two, "Basic principles of networking.") In some networks, is where the internal cable plant meets the outside world connectivity (the Demarco). Often, the MC is part of a larger room that contains server communications servers, file servers and sometimes even the desks of those working in network administration and support team.
35. In a star topology: all IC or HC are connected to the MC. The backbone cabling, or vertical, is used to connect the IC and HC from other floors. When the whole network is limited to a single multistory building, so
General MC will be located in one of the central story, although the demarcation point is located on the first floor or basement. For networks comprising several buildings, usually a building housing the MC and each individual building has its own point of concentration (IC) that connects all the HC that it contains.
36. The horizontal cabling networking including methods used in the area that extends from the wiring closet to a station
Work. The horizontal wiring includes the means for networking are
Stretched out along a horizontal path to take or connector
Telecommunications in the workspace, and connecting cables or jumper
In the HC.
According to the standards ANSI/TIA/EIA-568-B.1, the length of horizontal cable
Since the HC to the work area can not exceed 90 m (295.3 ft).
From there, the maximum length of cable from the station takes up
Work is 5m (16.4 feet). In the HC, the maximum cable length is 5m
(16.4 feet). This applies to all types of networking means
Category 5e UTP admitted.
37. as backbone cabling consists of: O vertical, consists of backbone cables, intermediate and main cross-connects, mechanical terminations and patch cables or jumper used in cross-connections of backbone A backbone. The backbone cabling includes
telecommunications rooms on the same floor (from MC to IC, IC to HC)
vertical connections (vertical lines) between the different TR
Flats (from MC to IC)
Cables between the TR and the demarcation point
Cables between buildings (within the same building) on campus with
Several buildings
38. what type of cables used for backbone:
39. which is a fiber optic Backbone:
Very effective means to move the backbone traffic.
This is because these fibers are impervious to electrical interference and radio frequency interference. In addition, fiber does not carry currents that can cause loops in the ground. Fiber optic systems also have a high bandwidth and can operate at high speeds. This means that now when you install a fiber optic backbone with certain characteristics, can be upgraded in the future for better performance when the computer connection is available. This can cause the optical fiber is very economical.
40. which is a multi-copper wire pairs: A method for moving large numbers of signals, like a backbone, is to use a multi-pair cable. A twenty-five pair cable may not be sufficient in a large infrastructure. The multi-pair cable for the use of backbone is available with several thousand pairs.
41. Cables that are the backbone of four pairs tied: fiber optic cables or multiple pairs are not an option, tie the four-pair cables for transport. At one time, the installers used to tie these wires on strict geometric designs such as squares or rectangles (sometimes called "cigarette packages). Although this may seem attractive, now this practice is not encouraged. First, it is difficult to make a simple "proof of lying" when choosing a cable harness, pull gently on one side and see what moves the other end. Second, by forcing the wires closely arranged can stress them and cause problems of radius of curvature. Finally,
Long parallel lines may enhance crosstalk between cables.
42. Connections that are jacks for multi-user telecommunications
(MUTO): Leading standards, we have included additional specifications
On horizontal wiring in work areas with furniture and partitions
Moving, even in TIA/EIA-568-B.1. Methodologies for wiring
Horizontal are specified to an environment of "open office" through connections for multi-user telecommunications outlets (MUTO) and
Consolidation points. These methodologies aim to provide greater flexibility
And economy for installations with office work spaces open
They require frequent reconfiguration.
43. guidelines for better use of MOTU: standard specifies TIA/EIA-568-B.1
at least one is required for each group MUTO furniture.
Can be used up to 12 areas of work for each MUTO.
277
connection cables in work areas should be labeled in
Both ends with unique identifiers.
The maximum length of cable is 22 m (72.2 feet).
44.
45. which are points of consolidation (PC): Provide a function similar to MUTO, but generally access to the point of consolidation is limited. In general, a CP is a panel that is permanently tack on the wall, ceiling or support columns that serve work areas where modular furniture. The panels must be unobstructed areas, which are easily accessible without moving any devices, equipment or heavy furniture. Consolidation points
MUTO differ from that equipment workstations and
Other areas of work is not plugged into the PC as they do MUTO. The
Workstations can be plugged into an outlet on telecommunications, which
It is then connected to the CP.
46. The TIA/EIA-569 standard specifies the following guidelines:
At least one PC for each group of furniture
A maximum of 12 areas of work for each CP
cross connections are not allowed
Maximum length of cable 5 m (16.4 ft
