GR-63-CORE Issue 5, released by Telcordia (now Ericsson) in December 2017, is the foundational standard for physical protection and environmental criteria for telecommunications equipment, with a focus on NEBS Level 3 compliance. The standard introduces updated requirements for fire resistance, seismic testing, and thermal conditions to ensure equipment durability in controlled environments. The full standard is available through authorized distributors, such as Intertek Inform and Telcordia's database .
