This document establishes the methods for a standard earthquake resistance test and determination of the earthquake resistance strength rank used to evaluate and rank the earthquake resistance strengths (physical damage and functional problems) of communications equipment in NTT DOCOMO, INC. . Ensure that the building can withstand an earthquake equivalent to intensity 7 (minimum value). Communications equipment enclosure 560 × 500 × 1800 mm, 150 kg JIS C 60068-3-3 Environmental test methods – Electrical and electronics – Guidelines for seismic test methods for equipment, JIS C. . When a 7. 8-magnitude earthquake struck Türkiye in February 2023, communication base stations with subpar seismic ratings collapsed within minutes, delaying rescue operations. This raises urgent questions: How do we quantify structural resilience in telecom infrastructure? What makes seismic. . Do earthquakes affect communication base stations? Analyzing and summarizing these observed seismic damages can enhance our understanding of the impairment of communication base stations during earthquakes, providing valuable information for establishing a Bayesian network model for functionality. . NTT DOCOMO has "Earthquake Resistance Standards for Communications Equipment" and "Earthquake Resistance Test Specifications for Communications Equipment" defined to apply to communications equipments with the view to securing their reliability and cost-effectiveness.
