ANSI SCTE 231-2019 pdf free download – General Test Procedures for Evaluation of Energy Efficiency Metrics and in Support of Functional Density Metrics.
1. Introduction
1.1. Executive Summary
A series of SCTE documents are being created to provide the cable operator with standard references fordetermining how well a piece of access network equipment performs in terms of minimizing the powerrequired to do its particular job. In addition, the standards provide the means to quantify the amount ofuseful work the equipment provides per physical space.This document supports the series of
supplemental standards by providing a common set of testing procedures and methodologies to be usedfor evaluating the power consumption metrics defined by those standards.
1.2. Scope
Cable operator networks are large expansive networks that involve hundreds if not thousands of miles ofcoaxial or fiber cable powered by power supplies in the outside plant and connecting customers to criticalinfrastructure facilities such as hubs, headends, data centers, regional, and national distribution
datacenters. In these facilities is a vast array of equipment responsible for the production and support ofthe cable operator’s products and services such as voice,video, data, home automation and security, andWi-Fi. The importance of powering all of these devices in the critical facilities is ever increasing as thecustomer expectation is for 100% availability due to the critical nature of the services being provided tobusiness and residential customers. Standard methodologies are needed to measure the energy
consumption for the various network element classes as well as measuring the density of hardware tomeet the needs of optimizing critical space.
This document covers the general test procedures that are common to all equipment types and specifiesthe environmental conditions for evaluating cable equipment energy efficiency metrics. Expectations ofmeasurement equipment as well as guidelines on the recording of results are also covered.This standardwill be included as a normative reference in each supplemental standard in the series covering metrics andspecific test procedures for the various equipment types.
The requirements in this document are applicable to all equipment types unless superseded by thatequipment type’s supplemental SCTE standard.
1.3. Benefits
This standard defines general testing configuration and procedures in support of energy-specific
performance metrics based on service features that are inherent to the type of equipment. This standardwill contribute to improve the overall energy footprint by enabling engineering driven decisions thatreduce energy consumption at the source of power consumption.
1.4. Intended Audience
Cable operator headend and hub engineers and testing staff, procurement teams, and operations staff;cable equipment vendor testing staff.
1.5. Areas for Further Investigation or to be Added in Future Versions
As the industry migrates towards Distributed Access Architectures (DAA), these specifications may beexpanded to accommodate these changes.
