2.2 Installation of the Hybrid IP-PBX
2.2.14 Lightning Protector Installation
Overview
A lightning protector is a device to 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 should be installed with lightning protectors. In addition, earthing
(connection to earth) is very important for the protection of the Hybrid IP-PBX.
Be sure to comply with applicable local regulations (e.g., law, guidelines).
