Technical Reference

Imagine trying to link railroads together that are based on different gauges, to build anything with
a combination of metric and American parts, to type a letter on something other than a QWERTY
keyboard, or to wire a building for voice, data and video if all the components had different requirements.
The key to simplifying all these tasks is standardization. Bringing standards to the wiring and cabling
segments of the building industry has enabled the industry to define a common infrastructure that allows
many companies to provide common components. Strict adherence to these standards benefits everyone.
ADC’s Position on Standards
ADC is a strong proponent of standards-based design for structured cabling systems. A strictly
defined set of standards helps ensure uniform application of physical layer networking products
and creates a usable infrastructure for communications networks.
However, ADC also believes that by nature, the standards evolve into a lowest-common denominator
indicator of performance. In order to accommodate various competing interests, a significant amount
of “flexibility” gets built into the allowable tolerances. The cumulative effect of these tolerances can
result in structured cabling channels in which different components can have radically different electrical
performance characteristics.
Consequently, when various standards-compliant components from randomly selected vendors are used,
the net result could be conformance to the standards, but not efficient performance.
The research undertaken by ADC for the TrueNet
®
structured cabling system revealed that only
a impedance-matched structured cabling channel that conforms to a tightly defined subset of the
performance standards is capable of flawless data transmission.
ADC, as a full system supplier, is able to deliver a complete system of impedance-matched components
so there is no guesswork. Choosing standards-compliant components randomly from unrelated vendors
will yield a standards-compliant channel, but may not result in optimum network performance.
Therefore, use the standards as a design guide, then make sure that you purchase standards-compliant
matched components.

Technical Reference
Entrance Facilities
The entrance facility provides a connection point between the outside plant facilities—whether it is
public network services, private network customer premises or a combination of both—and the interior
premises cabling. Products used in this area include cables, connecting hardware, special protection
devices and other connecting hardware.
The demarcation point separating the service provider’s cabling and the customer’s cabling may be

part of the entrance facilities. Because the location of the demarcation point is determined by state
and federal regulations, the local regulated carrier (telephone service provider) or competitive access
provider should be contacted for detailed information.
The primary standards for this area are outlined in TIA/EIA-569-A, Commercial Building Standard
for Telecommunications Pathways and Spaces, and J-STD-607-A, Commercial Building Grounding/
Bonding Requirements.
ADC manufactures special overvoltage blocks, protection devices and building entrance terminals
for both fiber and copper cabling for use in this area.
Equipment Rooms
The TIA/EIA-568-B Series standard makes a distinction between equipment rooms and telecom-
munications rooms because of the nature of complexity of the equipment they contain. However, an
equipment room may alternately provide any or all of the functions of a telecommunications room.
Equipment rooms provide a controlled environment to house telecommunications equipment.
This equipment may include connecting hardware, splice closures, grounding and bonding facilities
and protection devices, where applicable. Switches, routers and other active equipment may reside
in the same rack or cabinet space as the passive cabling infrastructure.
In the premises cabling backbone hierarchy, an equipment room may contain either the main
cross-connect or the intermediate cross-connect. The equipment room may also contain network trunk
terminations and auxiliary terminations that are under the control of the premises cabling administrator.
The primary standards for this area are outlined in TIA/EIA-569-A, Commercial Building Standard
for Telecommunications Pathways and Spaces.
ADC manufactures a wide variety of fiber and copper patch panels, termination blocks and cable
management solutions that are well suited for this area.
Telecommunications Rooms
Telecommunications rooms may provide various functions for the cabling system and because of this
they are treated as a distinct subset in the cabling system hierarchy.
The primary function of a telecommunications room is to provide a termination point for horizontal
cable distribution, that supports all voice, data, video and other applications requiring structured
cabling. The telecommunications room also serves as a termination point for backbone cable.
The cross-connection of these two parts of the premises cabling is an important function of the

telecommunications room. Cross-connections may be accomplished using jumper wires or patch cords,
and ADC products handle both methods equally well.
Telecommunications rooms may also house cross-connects for different portions of the backbone
cabling system. These cross-connects are sometimes used to tie different rooms together in a ring, bus
or tree configuration.

Telecommunications rooms also provide a controlled environment for specific areas of a building. These
rooms may house telecommunications equipment, connecting hardware and splice closures as well as
devices such as routers and hubs. In some instances, the demarcation point and protection devices may
be located in a telecommunications room.
The TIA/EIA-568-B Series standard details cable routing and installation practices for telecommunications
rooms to prevent cable stress and to properly organize and manage cables.
Additional standards for this area are outlined in TIA/EIA-569-A, Commercial Building Standard for
Telecommunications Pathways and Spaces.
ADC manufactures a wide variety of blocks and patch panels capable of providing termination and
cable management for a wide range of wire sizes and cable types found in telecommunications rooms.

Technical Reference
The TIA/EIA-568-B Series standard addresses two basic wiring schemes for the telecommunications
room: interconnection and cross-connection.
Both the backbone and the horizontal cabling are terminated on connecting hardware that meets
the requirements of the TIA/EIA-568-B Series standard. However, the standard prohibits the use of these
terminations for moves, adds and changes. Any connection between the backbone and horizontal
cabling must be accomplished through the use of a “horizontal cross-connect” between the common
equipment and the connecting hardware to which the horizontal cabling is terminated. This connection
may be made using an interconnection or a cross-connection cabling scheme.
An interconnection is a cabling scheme that provides for a direct connection between two cables
without the use of patch cords or jumper wires.
A cross-connection is a cabling scheme between cabling runs, subsystems and equipment using

patch cords or jumper wires that attach to connecting hardware on each end.
Common equipment that utilizes cables that extend an individual port may be permanently terminated
or interconnected to the connecting hardware for the horizontal cabling. Direct interconnections such as
this reduce the number of connections in a channel, but may also reduce the flexibility, especially as the
volume of moves, adds and changes increases.

Backbone Cabling
Backbone cabling provides interconnections between the telecommunications rooms, equipment
rooms and entrance facilities. Backbone cabling consists of cables, main and intermediate cross-connects,
mechanical terminations and patch cords or jumper wires. Backbone cabling can be within buildings
(intrabuilding) or between buildings (interbuilding).
The TIA/EIA-568-B Series standard requires that backbone cabling use a hierarchical star topology.
Each horizontal cross-connect in a telecommunications room is cabled to an intermediate cross-
connect and then to a main cross-connect (or directly to a main cross-connect), with no more than two
hierarchical levels of cross-connect in the backbone cabling. These cross-connects may be located in
telecommunications rooms, equipment rooms or entrance facilities.
Recognized cables for use in backbone
cabling include the following:

100 Ohm UTP (unshielded twisted pair)
cable (four or more pairs)
150 Ohm STP-A (shielded twisted pair) cable
62.5/125µm, multimode optical fiber cable
50µm, multimode optical fiber cable
Singlemode optical fiber cable
Backbone cabling uses a hierarchical star topology.

Horizontal Cabling
Horizontal cabling extends from the work area telecommunications outlet to the horizontal cross-connect
in the telecommunications room. Horizontal cabling includes the cables, the telecommunications outlet
in the work area, the mechanical termination and patch cords or jumper wires and cable management
solutions located in the telecommunications room.
• Voice service

• Internet service

• Video and conferencing services

• Premises switches, routers and hubs

• Data communications to support fax,

storage servers, network printers

• Local area networks (LANs)

• Life safety systems such as security,

fire alarm and door entrance

• Automation systems such as lighting

and HVAC control

• Other building signaling systems,

such as CCTV, nurse call, paging,

audio and others
Relocation of offices is a common occurrence in enterprises. Horizontal cabling is often one of the
more dynamic areas of the premises system. However, after installation, horizontal cabling is often much
less accessible than backbone cabling, and the time, effort and skills required to change or modify it
can be extremely high. Horizontal cabling should be designed with the intention of minimizing ongoing
maintenance and relocation so that moves, adds and changes can be accomplished from the telecom-
munications and equipment rooms. Additional consideration should be given to accommodating a wide
range of applications in order to reduce the necessity of changes to the cabling as users’ needs evolve.

Care should be given to separate telecommunications cabling from electrical facilities that generate
high levels of electromagnetic interference (EMI). Fluorescent lights, copy machines, heating/cooling devices,
motors and transformers that support the building’s mechanical requirements all contribute to EMI. TIA/
EIA-569-A specifies separation of horizontal cabling pathways from common sources of EMI.
Horizontal cabling is required to use a star topology. Each work area telecommunications outlet is to be
connected to a horizontal cross-connect in the telecommunications room. Each work area is to be served
by a telecommunications room.
Maximum Distances
The maximum distance of a copper horizontal cabling run is 90 meters (approximately 295 feet) from
the mechanical termination at the horizontal cross-connect in the telecommunications room to the
telecommunications outlet in the work area.
Cross-connect jumper wires and patch cords used in the cross-connect facilities should not exceed
six meters in length (approximately 20 feet).
