TIA Updates Residential Telecommunications Infrastructure Standard

Addendum Includes Additional Requirements for Broadband Coaxial Cabling

Arlington, Va. – The Telecommunications Industry Association (TIA), the leader in advocacy, standards development, business development and intelligence for the information and communications technology (ICT) industry, recently released an addendum to ANSI/TIA-570-B Residential Telecommunications Infrastructure Standard: TIA-570-B-1 Addendum 1 – Additional Requirements for Broadband Coaxial Cabling.

In 2005, TIA recognized that there was no single standard, including ANSI/TIA-570-B, which contained the requirements for a coaxial cabling system capable of supporting current and emerging technologies. TIA agreed to develop these requirements as an addendum, TIA-570-B-1, to ANSI/TIA-570-B. The addendum replaces and supersedes the requirements for coaxial cabling, cables, and connectors in ANSI/TIA-570-B.

TIA-570-B-1 establishes performance and technical criteria for coaxial cabling system configurations for accessing and connecting their respective elements. In order to determine the requirements of a generic coaxial cabling system, performance requirements for various telecommunications services were considered.

TIA-570-B-1 specifies additional requirements and recommendations for 75 ohm broadband coaxial cabling, cables, cords and connecting hardware to support community antenna television (CATV, commonly referred to as cable television), satellite television and other applications in single- and multi-dwelling residential buildings as part of a telecommunications infrastructure as defined by ANSI/TIA-570-B. Included are transmission and mechanical requirements and requirements related to electromagnetic compatibility (EMC) for cabling, cables and connectors; cabling installation and connector termination procedures; and field testing procedures.

The diversity of services currently available, coupled with the continual addition of new services, means that there may be cases where limitations to desired performance occur. When applying specific applications to these cabling systems, users are cautioned to consult application standards, regulations, equipment vendors, and system and service providers for applicability, limitations, and ancillary requirements.

TIA-570-B-1 was formulated under the cognizance of TIA Engineering Committee TR-42 User Premises Telecommunications Cabling Requirements, TR-42.2 Subcommittee on Residential Telecommunications Infrastructure.
