5.2 STRUCTURED BUILDING TELECOMMUNICATION SYSTEMS Flashcards
Prior to ________, End-users were frequently confused by manufacturers’ conflicting claims concerning TRANSMISSION performance and were forced to pay high installation and administration costs for __________ systems.
1991, proprietary
The __________________________ (EIA), ____________________ (TIA), and a large consortium of leading telecommunications companies worked cooperatively to create the _________________________ (ANSI)/TIA/EIA-__________ Commercial Building Telecommunications Wiring Standard.
Electronic Industries Association
Telecommunications Industry Association
American National Standards Institute
568-1991
The ANSI/TIA/EIA-568-1991 was revised in 1995, and is now referred to as ANSI/TIA/EIA-568- A Commercial Building Telecommunications _________ Standard.
– goal of these standards is to define ____________ a telecommunications cabling system that can support virtually any voice, imaging, or data application that an end-user chooses.
Cabling, structured cabling
_______________ is the medium through which voice and data move from one TELECOMMUNICATION DEVICE to another. Cabling _________ carries _________ or _________ signals to and from devices and equipment in a telecommunication system.
Telecommunication cabling, physically, electrical, optical
___________ is a passageway, and thus a path, for cable to travel when interconnecting devices, components, and equipment in a telecommunication system.
pathways
_____________ are typically a raceway, a channel, or trough designed
to hold wires and cables.
Pathways
( T/F)
Pathways can carry existing cable and does not allow additional
cabling to be installed to accommodate the addition of equipment or upgrades in technology.
F, it easily allow
_______________ is a generic term used to describe a main pathway or cabling media that interconnects a number of telecommunication devices.
backbone
Backbone is used to connect networks in a building or in separate buildings. ______________ is typically used for this type of backbone.
Fiber optic cable
______________ may be attached from the backbone to connect individual workstations.
Drop cables
A _______________ is the cabling, devices, and equipment that INTEGRATE the voice, data, video, and electronic management systems of a building.
structured cabling system
The ______________ is the cabling and pathways _________ of the building and caries telecommunication services to the building these includes:
• _______ carrying local exchange carrier (LEC) services
(e.g., outside telephone company)
• Internet service provider services
• ____________ telecommunication cable
(e.g., private phone network between buildings at a school campus or business park)
interbuilding backbone, outside
Cables
Private branch exchange
The _______________________ is an entrance to the building for both public and private network service cables. It includes the cables, connecting hardware, protection devices, and other equipment
needed to connect the ____________ backbone cabling to the backbone cabling in the building.
building entrance facility, interbuilding
In buildings with a finished floor area larger than _____________ ft² (1870 m²), a secured (locked), dedicated, _________ room is recommended for the building entrance. An industry standard is to allow __ ft² (0.1 m²) of ___-in (20-mm) plywood wallmountarea for each _______ ft² (19m²) area of finished floor area.
20,000, enclosed, 1 , 3/4, 200
Serves a building or multiple building in a campus or business park environment and the building entrance facilities
It is a room dedicated to provides a CONTROLLED ENVIRONMENT to the important equipments.
It is a centralized space for housing main telecommunications equipment.
Telecommunications Equipment Room
-DEDICATED ROOM ON EACH FLOOR in a building that houses INTERMEDIATE voice and data telecommunications equipment and related cable connections.
- serves as a location where JUNCTIONS between the backbone pathway and horizontal pathways are made at one or more patch panels.
- large buildings will have several ________________ and should be located in a space that is central to the work areas it serves.
Telecommunications Closet x2
-a MOUNTED hardware unit containing an assembly of rows of connecting locations in a communications system, called PORTS.
-located in a TELECOMMUNICATIONS CLOSET to serve as a type of switchboard-like device in a network.
patch panel
is receptacle that is a specific place for physically connecting a device or piece of equipment to another.
Port
a cable that is used to create a connection from one port in a patch panel to another port.
Patch Cord
____________ is the recommended closet size More than 1 telecommunications closet if area exceeds 90m or 940
squares meters.
10 ft x 12 ft
Two walls in a telecommunications closet should be covered with __ft high, ___ mm thick wood to attach equipment.
8, 20
Telecommunications closet should be stacked vertically
above each other or else __in horizontal conduit runs are
required with no more than ___ deg bends between pull
points.
4, 90
An industry standard is to provide at least three 4-in diameter sleeves (a stub of conduit through the floor) per 50000 ft-squared.
FACT
multiple telecommunications closets on a single floor
must be _______________.
interconnected
