What does ANSI/TIA-570 outline?

• A. Classes of wireless devices
• B. Grades of VDV service for residential premises
• C. Networking cable types
• D. Fire safety regulations

Answer: (B)

The ANSI/TIA-570 standard outlines the grades of Voice-Data-Video (VDV) service for residential premises, focusing on the structured wiring necessary to support a wide range of services. This standard provides guidelines and specifications for the infrastructure that enables high-quality communication and media services within homes. It addresses the types of cabling, installation practices, and performance criteria required to ensure that systems operate efficiently and reliably.

This standard is important because it helps ensure that residential areas have the proper infrastructure to support advanced telecommunications, including voice, video, and data services. By categorizing different grades of service, ANSI/TIA-570 helps designers and installers create systems that meet the specific needs of homeowners and comply with industry standards.
