Standards

The importance of standards

The importance of standards in today’s structured cabling

systems can’t be underestimated.

A standards-based system provides a generic base for building

a communications infrastructure without compatibility worries.

Standards establish

technical criteria

and ensure uniform

performance among

network systems and

components. They enable

you to build modular

networks that can easily

accommodate new technologies,

equipment, and users.

Before 1985, there were no

structured cabling standards. Phone

companies used their own cabling.

Businesses generally used a vendor’s

proprietary system. Eventually, the

Computer Communications Industry

Association (CICIA)

approached the Electronics

Industries Alliance, formerly

Association, (EIA) about

developing cabling standards,

which they did. Discussions

centered around developing

standards for voice,

data, commercial, and

residential cabling

systems. (The TIA

was formed

in April 1988

after a merger

of the United States

Telecommunications Suppliers Association

and the Information and Telecommunications Technologies

group of the EIA. Thus the TIA/EIA.)

In 1991, the TIA/EIA published its Commercial Building

Telecommunications Wiring Standard, TIA/EIA-568. It was

the first standard to define a generic telecommunications system

that would support a multiproduct, multivendor environment.

It enabled wiring systems to be planned and installed without

definite plans for telecommunications equipment installed later.

The standards committees meet and review standards every

five years, and the issuance of TSB (Technical Service Bulletins)

is on-going. The TIA/EIA has issued a number of standards covering

everything from types of cabling, cabling installation, administration,

and more. This guide covers the most relevant standards to

commercial buildings.

Standards organizations.

Today, there are a number of organizations developing

standards related to cabling and communications.

ANSI (American National Standards Institute). This group

coordinates and adopts national standards in the U.S.

EIA (Electronics Industries Alliance). Best known for developing

cabling standards with the TIA, this trade organization is accredited

by ANSI to help develop standards on electronics components,

telecommunications, Internet security, and more.

TIA (Telecommunications Industry Association). Best known

for developing cabling standards with the EIA, the TIA is the

leading trade association for the information, communications,

and entertainment technology industry. The TIA provides standards

development and represents the communications sector of the

Electronics Industries Alliance (EIA).

ISO (International Organization for Standardization). This group

is the world’s largest developer of standards and includes standards

groups from member nations around the world.

IEC (International Electrotechnical Commission). This international

standards organization prepares and publishes international standards

for all electrical, electronic, and related technologies.

IEEE (Institute of Electrical and Electronics Engineers, Inc.).

This international organization is a leading developer of industrial

standards in a broad range of disciplines, including electric

power, information technology, information assurance,

and telecommunications. This group is known for its 802.3

committee, which sets the standards for Ethernet.

BICSI (Building Industry Consulting Service International, Inc.).

This association supports the information transport systems (ITS)

industry with information, education, and knowledge assessment.

CSA (Canadian Standards Association). Electrical and electronic

goods in Canada must be CSA approved.
