Chapter Review

The organizations that develop and publish the primary standards covering the specification and installation of residential system wiring are: ANSI, EIA, IEEE, ISO, NFPA, TIA, UL, and OSHA.

ANSI is an agency of the United States federal government that is charged with the responsibility of developing and approving standards that cover a variety of technology, including computers and data communications, and weights and measurements. ANSI works with other agencies to develop and publish standards. Examples of jointly issued standards are the ANSI/TIA/EIA 568, 569, and 570 wire and cabling standards.

EIA is an alliance of trade and industry associations that work together to sponsor and promote data communication standards. Most of the EIA standards that apply to residential wiring are issued jointly with ANSI and TIA, including the ANSI/EIA/TIA 568 and 570 standards.

The IEEE is a worldwide, technical, professional association of engineers that is a leading standards authority in a variety of technical areas. The IEEE standards include the 802 computer networking standards.

The ISO is an international, non-treaty organization of voluntary members that develops and maintains a variety of technology standards, including standards governing computers, networking, and communications. An emerging standard of ISO is the residential gateway, which defines a network interface device that provides service access to a home for such services as telephone, cable television, and Internet access.

The NFPA is an international association focused on the development and publishing of fire safety codes, standards, and research to minimize the possibilities and impact of fire and other safety risks. The NFPA publishes the National Electrical Code (NEC), which includes coverage for the installation of electrical conductors, including the wiring used in structured residential wiring systems.

TIA is a trade organization of telecommunication product and service providers that develops and publishes a variety of wire and media specifications and testing standards for residential applications. The TIA/EIA 568 and 570 standards govern Cat 5 wiring connections and testing for home networking installations.

UL is an independent, nonprofit product safety testing organization that tests cable and wire products for fire and electrical safety testing against the NEC and other NFPA standards.

The primary home technology standards are ANSI/EIA/TIA wiring standards, IEEE Ethernet wire standards, the NEC, the OSHA job safety practices, and the International Building Code (IBC).

The ANSI/EIA/TIA 568 standard provides specification for generic telecommunication cabling that prescribe the performance testing criteria for standard system configurations and their components . The 568 standards specify horizontal cable, work area or room cabling, and central distribution termination. The 568 standards also specify the UTP cabling categories for use as horizontal cabling and patch cords.

The 568 standard defines two separate cable termination standards for UPT cabling: 568a and 568b. The 568 standards also specify IDC (Insulation Displacement Connector) connectors at the distribution or telecommunications center and the use of the RJ-45 connector.

The EIA/TIA 570 standard defines the basic requirements for residential structured wiring and is the nationally accepted standard covering the design and installation of low voltage wiring in residential dwellings.

The IEEE 802 standards designate network media standards for use on an Ethernet network with a special coding scheme that generally describes a media’s characteristics. The National Fire Protection Association (NFPA) publishes the National Electric Code (NEC) as a guideline to avoid and prevent electrical shock and fire hazards from residential wiring systems.

Each country has a governmental agency that publishes job safety and health codes and regulations. In the United States, it’s the Occupational Safety and Health Administration (OSHA); in Canada, it’s the Human Resources Development Canada (HRDC); in England, it’s the Health and Safety Executive (HSE); and in Japan, it’s the Japan Occupational Safety and Health Office (JOSHO). OSHA publishes the “Selected Construction Regulations (SCOR) for the Home Building Industry (29 CFR 1926).”

The term “powerline” describes the use of the electrical lines inside a home’s walls to transmit information. The three primary standards for powerline technology are CEBus, HomePlug, and X-10. Phoneline communications technologies use the existing telephone wiring or coaxial cable in the walls of a home to communicate. The leading phoneline standard is the Home PhoneLine Networking Association (HPNA) standard. The primary wireless media standards are IEEE 802.11a, IEEE 802.11b, Bluetooth, and HomeRF.
