Summary

Recommendation ITU-T L.330 identifies facilities, items, typical frequency and criteria to be inspected by operators, along with fundamentals of telecommunication infrastructure facility management. Its intended users are not only operators who need to improve life-cycle management, but also developers who consider applying rapidly progressing technologies.

Extensive outside telecommunication infrastructure facilities that support information technology continue to deteriorate due to aging. To provide telecommunication services continuously and to upkeep infrastructure safety, it is important to maintain service functions based on appropriate facility management as a series of maintenance tasks that includes inspection, diagnosis and repair. Demand is dramatically increasing for cost-effective technologies that can improve maintenance productivity for various types of infrastructure.
