Electrical Protection for Ethernet Systems
|Publication Date:||1 October 2017|
The purpose of this ATIS Standard is to assist the service provider in choosing appropriate protection methods for Ethernet communications circuits. This ATIS Standard describes protector characteristics that may impact Ethernet 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 state and their effect 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 the Broadband umbrella document ATIS-0600012, Electrical Protection Considerations for Broadband Systems.
This ATIS Standard applies to the electrical protection at all Ethernet network equipment locations. Examples include: Ethernet equipment at Central Office (CO) Type facilities, remote sites, and at the customer location [including the entrance or interface point, and Customer Premises Equipment (CPE)]. This equipment may interface with various types of cable media, such as coaxial cable or twisted pair that provides the Ethernet signal and possible power.
Although a variety of existing and proposed Ethernet equipment types are considered, the merits of the different technologies, and/or architecture types, are not covered.
The following are examples of equipment/items included in this ATIS standard:
- Primary protectors.
- Secondary protectors.
- CO equipment.
- Remote terminal equipment.
- Cell Site equipment.
- NIDs, iNIDs, NIUs, ONTs, ONUs, BETs, and other points of demarcation.
- CPE such as Set-Top Boxes (STBs), xDSL splitters, telephones, etc.
- Traffic security cameras, WiFi, Wi-max, and hot spots
