عربي | 中文 | English | Español | Français | Русский
Monitoring systems for outside plant facilities
Natural disasters such as those caused by strong wind, flood, landslide, and earthquake happen more frequently than ever and their damage is increasing. Human-caused disasters such as those caused by fire, explosion, and collapse also happen on a large scale. Outside plant facilities including telecommunication buildings are exposed to these disasters and may be affected adversely, which implies that preventive measures are needed. Recommendation ITU-T L.81 deals with monitoring systems to mitigate damage and to secure outside plant facilities against disasters.
