6.2.11 Lightning Protector Installation
Overview
A lightning protector is a device that must be installed on a trunk to prevent a dangerous surge
from entering the building and damaging equipment.
A dangerous surge can occur if a telephone line comes in contact with a power line. Trouble
due to lightning surges has been showing a steady increase with the development of electronic
equipment.
In many countries/areas, there are regulations requiring the installation of lightning protection.
A lightning strike to a telephone cable which is 10 m above ground can be as high as 200 000 V.
The Hybrid IP-PBX must be installed with lightning protectors. In addition, earthing (connection
to earth) is very important for the protection of the user.
Be sure to comply with applicable local regulations (e.g., law, guidelines).
