TELECOMMUNICATIONSSPACES

WORK AREA • WA •

Work Area

• Work Areas are those spaces in a building where occupants interact with their telecommunications devices

• Work Area elements are situated between the Horizontal cabling system end point on the Telecommunications Outlet and Work Area active equipment

• The Work Area cabling system efficiency has a great impact on the distribution system operation

• The special feature of the Work Area cabling system is its versatility and ability to introduce changes easily

Work Area

• Work Area elements are:

– Telecommunications Outlet or Multiuser Telecommunications Outlet

– Equipment cables (cords)

– Adapters, converters, couplers/splitters

– Telecommunications equipment (telephones, computers, modems, terminals, etc.)

• Active telecommunications equipment and adapters (converters, couplers) are not considered part of the telecommunications cabling system and are not included into the Signamax Cabling System

Telecommunications Outlet

• Telecommunications Outlet/connector is a fixed connecting device where the horizontal cable terminates

• The Telecommunications Outlet/connector provides the interface to the Work Area cabling

• The Telecommunications Outlet/connector in the Work Area is the point at which end-user equipment "plugs into" the building telecommunications utility formed by the pathway, space, and building cabling system

• The Telecommunications Outlet/connector at the same time is an element of the Work Area and Horizontal subsystem

Telecommunications Outlet

7 Specialized devices designed to support specific applications shall not be used as part of the Horizontal cabling subsystem of the Signamax Cabling System, and, in case of application they shall be kept external to the Telecommunications Outlet

Outlet Mount Box

• The mounting box of the Telecommunications Outlet is an intermediate element between the Horizontal subsystem cable and the Work Area cable

• The following are the most widely used ways to install the mounting boxes:

– in or on the wall (or on any surface applicable for mounting)

– in the perimetral pathway (cable raceway)

– in the furniture pathway

– on the flexible hose or conduit.

Outlet Mount Box

9 Telecommunications Outlet shall provide

• termination protection• support the required bend radii• ensure the recommended cable slack of

the Horizontal cabling subsystem

TELECOM ROOM • TR •

Telecommunications Room

• Telecommunications Rooms (TRs) offer many different functions to the cabling system and are often considered as a distinct subsystem within the hierarchical cabling system

• The most important function of a Telecommunications Room is the termination of Horizontal and Backbone subsystem cables to compatible connecting hardware

• A Telecommunications Room may also includethe Intermediate Cross-connect or the Main Cross-connect for different parts of the Backbone cabling subsystem

Telecommunications Room

• A Telecommunications Room provides the means for administration and routing of the equipment cables/cords from the Horizontal Cross-connect to the telecommunications equipment

• In some cases, the Demarcation Point and associated protection apparatus may also be located inthe Telecommunications Room

• A Telecommunications Room also provides a controlled environment to house telecommunications equipment, connecting hardware, and splice closures serving a part of the building

Space

4 The Telecommunications Room space shall be designed and equipped to provide installationof active telecommunications equipment, connecting hardware for termination of Backbone and Horizontal subsystems and cross-connect cabling(cross-connect jumpers, equipment and patch cords)

Location and Size

3It is recommended thatthe TelecommunicationsRoom be located onthe same floor asthe Work Area it serves

8 Work Areas shall be servedby the Horizontal Cross-connect located inthe TelecommunicationsRoom on the sameor adjacent floor

Location and Size

• Based on standards Work Area sizes 10 m2 (100 ft2), recommended minimum sizes of the Telecommunications Room can be found in the table below

Floor Serving Area,m2 (ft2) TR Size, m (ft)

1,000 (10,000) 3.0 х 3.4 (10 x 11)

800 (8,000) 3.0 х 2.8 (10 x 9)

500 (5,000) 3.0 х 2.2 (10 x 7)

Alternative Spaces

• In buildings with total size of the service area of up to 500 m2 (5,000 ft2), on floors with service area size of up to 100 m2 (1,000 ft2) and in cases when there is no opportunity to make a separate TR on the floor, small closets (for example, built-in closets) and equipment cabinets(floor and wall mount) can act as TRs

Alternative Spaces

13Equipment cabinets can be used in the Signamax Cabling System as a Telecommunications Roomif they are protected against unauthorized access, located in a strictly fixed place and all applicablecodes such as electrical and occupational safety regulations are complied with

EQUIPMENT ROOM • ER •

Equipment Room

• The main function of the telecommunications Equipment Room is to provide a specially equipped area to terminate Backbone subsystem cables on connecting hardware of the Main and Intermediate Cross-connects

• Equipment Rooms (ERs) are considered different from Telecommunications Rooms because of the nature or complexity of the equipment contained in them

• An Equipment Room may provide any or all of the functions of a Telecommunications Room or Entrance Facility

Equipment Room

• An Equipment Room provides a controlled environment to house telecommunications equipment, connecting hardware, splice closures, grounding and bonding facilities, and protection apparatus where applicable

• An Equipment Room may also house equipment terminations (and may contain Horizontal subsystem terminations for a part of the building)

• In many cases, the Equipment Room has access provider trunk terminations, premises network terminations, Demarcation Point (DP), and auxiliary terminations

Space

4 The Equipment Room space shall be designedand equipped to provide installation of active telecommunications equipment, connectinghardware for termination of Backbone andHorizontal subsystems and cross-connect cabling (cross-connect jumpers, equipment and patch cords)

Location and Size

• The Equipment Room should be sized so as to comply with the known requirements of specific equipment

• Sizing should include expected future as well as present requirements

• Where a room or space is intended to be used for more than equipment (e.g., equipment and either or both the Cross-connect/main terminal and Entrance Facility hardware), it shall be increased in size accordingly

• When during the Equipment Room design the type of equipment to be installed there is unknown, (for example, when designing a new general-purpose office building), the following rules should be followed

Size

3When designing the Equipment Room floor space, 0.07 m2 (0.75 ft2) of Equipment Room space for every 10 m2 (100 ft2) of Work Area space should be allowed.

The Equipment Room should be designed to a minimum of 14 m2 (150 ft2)

ENTRANCE FACILITY • EF •

Entrance Facility

• The Entrance Facility (EF) consists of the telecommunications service entrance to the building, including the entrance through the building wall, and continuing to the entrance room or space

• The Entrance Facility may contain the Backbone pathways that connect to the Main or Intermediate Cross-connect and to other buildings in campus situations

• Antenna entrances may also constitute part of the Entrance Facility

Entrance Facility

• The Entrance Facility includes the cables, connecting hardware, protection devices, and other equipment required to connect the outside plant facilities to the premises cabling

• The Demarcation Point (DP) between the regulated access providers and the customer premises cabling may be part of the Entrance Facility

Pathways and Spaces

• The entrance room or space is the element of the Entrance Facility that gives space for the placing and termination of protectors on the entrance cable and may include network interface devices

• If network interface devices and telecommunications equipment are necessary in the entrance room, additional space will be required

• Where an entrance room or space is intended to be used for more than protectors and interfaces (e.g., PBX equipment, cross-connect termination fields), its size shall be increased accordingly

Pathways and Spaces

4 The Entrance Facility space shall be designed and equipped to provide installation of active telecommunications equipment, connecting hardware for termination of Backbone and Horizontal subsystems and cross-connect cabling(cross-connect jumpers, equipment and patch cords)

8 The Entrance Facility room or space shall be located in a dry area not subject to flooding
