The objective of Supplement X to the ITU-T K-series Recommendations, Additional criteria to protect telecommunication cabling in the event of a power cross event, is enable the implementation of power cross protection for telecommunications cabling connected to [b-ITU-T K.20], [b-ITU-T K.21] and [b-ITU-T K.45] compliant equipment.

This Additional criteria to protect telecommunication cabling in the event of a power cross event supplement aims to:

• Explain the evolution of physical wiring simulators and their drawbacks

• Provide designers with the tools to extrapolate the supplement current-time limitations data to larger and smaller conductor sizes.
