Electrical Protection

The purpose of this ATIS Standard is to assist the service providers, network designers, and system integrators in choosing appropriate protection methods for G.fast communications circuits. It describes protector characteristics that may impact G.fast systems for outside plant, intra and inter-building applications, and the services provided over these links. These protectors are categorized by technology type and configurations.

This document describes protectors in their non-operating states and their effects on these services and also considers the effects of protector response to a surge event and how that operation may affect these services. This is a subtending document and is intended to be used with and is in support of the Broadband umbrella document, ATIS-0600012, Electrical Protection Considerations for Broadband Systems.

Equipment Covered

This ATIS Standard applies to the electrical protection at all G.fast equipment locations. Examples include: G.fast equipment at Central Office (CO)-type facilities, remote sites, and customer location (including the entrance or interface point, and Customer Premises Equipment [CPE]).

The following are examples of equipment/items included in this ATIS Standard:

• Primary protectors.
• Secondary protectors.
• Tertiary protectors.
• CO equipment.

Remote Terminal equipment.

Network Interface Devices (NIDs), Integrated/Intelligent Network Interface Devices (iNIDs), Network Interface Unit (NIUs), Optical Network Terminal (ONTs), Building Entrance Terminals (BETs), and other points of demarcation.
