21、Institute, Inc. Abstract This document defines how to measure the Telecommunication Energy Efficiency Ratio (TEER) of DC/DC Converters. The standard also provides requirements for how equipment vendors shall respond to a TEER request based on a specific application description by making use of relev
22、ant data from internal and independent test reports. ATIS-0600015.11.2016 ii Foreword The information contained in this Foreword is not part of this American National Standard (ANS) and has not been processed in accordance with ANSIs requirements for an ANS. As such, this Foreword may contain materi
23、al that has not been subjected to public review or a consensus process. In addition, it does not contain requirements necessary for conformance to the Standard. The Alliance for Telecommunication Industry Solutions (ATIS) serves the public through improved understanding between providers, customers,
24、 and manufacturers. The Sustainability in Telecom: Energy and Protection (STEP) Committee formerly the Network Interface, Power, and Protection Committee (NIPP) engages industry expertise to develop standards and technical reports for telecommunications equipment and environments in the areas of ene
25、rgy efficiency, environmental impacts, power, and protection. The work products of STEP enable vendors, operators, and their customers to deploy and operate reliable, environmentally sustainable, energy efficient communications technologies. STEP is committed to proactive engagement with national, r
26、egional, and international standards development organizations and forums that share its scope of work. ANSI guidelines specify two categories of requirements: mandatory and recommendation. The mandatory requirements are designated by the word SHALL and recommendations by the word SHOULD. Where both
27、 a mandatory requirement and a recommendation are specified for the same criterion, the recommendation represents a goal currently identifiable as having distinct compatibility or performance advantages. Suggestions for improvement of this document are welcome. They should be sent to the Alliance fo

34、logy to be used by vendors and third party independent laboratories in the formation of a Telecommunications Energy Efficiency Ratio (TEER). The requirements and definitions in this document are for DC/DC converters that are deployed in the telecommunications industry. This standard represents one p
35、art of the larger ATIS suite of standards concerning Telecommunications Energy Efficiency (ATIS-0600015.11.2016). This standard (ATIS-0600015.11.2016) specifically addresses DC/DC converters and is to be used in conjunction with ATIS-0600015. 1.2 Purpose This document provides a set of definitions,
36、requirements, and guidelines for calculating the Telecommunications Energy Efficiency Ratio (TEER) of DC/DC converter products. The test methodology employed to verify the power consumption, used as part the TEER calculation, is specific to power equipment and therefore differs from ATIS-0600015. 1.
37、3 Application This document (and supporting documentation) is intended to be used by communication network operators, equipment manufacturers, suppliers, and test laboratories as a standard method for determining the energy efficiency of DC/DC converters. By comparing the TEER reports of various pro
38、ducts, a communications network operator can select equipment that meets their energy efficiency target. 2 Normative References The following standards contain provisions which, through reference in this text, constitute provisions of this ATIS Standard.
