This standard presents engineering design procedures for the electrical protection of metallic wire-line telecommunication facilities serving electric supply locations through the use of on-grid isolation equipment. Other telecommunication alternatives, such as radio and microwave systems, are excluded from this document.
This standard presents engineering design procedures for the electrical protection of telecommunication facilities serving electric supply locations through the use of optical fiber systems for the entire facility. Other telecommunication alternatives such as radio and microwave systems are excluded from this document.
