ATIS 0600030.2021

There are various standards that define telecommunications line-powering voltage limits, power limits, and safety-related precautions. This standard attempts to bring all those requirements into one document. This standard also addresses performance of line-, express-, and span-powering systems (also known as Remote Feeding Telecommunications Circuits [RFT]) in fault conditions and provides manufacturers, installers, and users of line power systems with a consistent fault condition testing and recording method. The fault current levels determined through this analysis can be compared to standards IEC 60479-1, Effects of Current on Human Beings and Livestock, Part 1- General Aspects and IEC 60479-2, Effects of Current on Human Beings and Livestock, Part 2- Special Aspects.
