The standard provides the methodology by vendors and third party independent laboratories in the formation of a telecommunications energy efficiency ratio. The requirements and definitions in this document are for Wireline Access equipment that provides standards-based asymmetric broadband service and is deployed in the telecommunications industry. This supplemental standard represents one part of the larger ATIS suite of standards concerning Telecommunications Energy Efficiency (ATIS-0600015). This supplemental standard (ATIS-0600015.07.2013) specifically addresses access equipment and is to be used in conjunction with ATIS- 0600015. The initial scope is limited to this specific type of equipment. The current document addresses asymmetric Broadband equipment that includes Digital Subscriber Line Access Mulitplexers (DSLAMs) with ADSL or VDSL technology. Symmetric DSL technologies@ vectoring@ self-test@ and bonding are not included within this standard. Other categories of Access Equipment may be addressed in other supplemental standards. This may include Optical Access@ Edge equipment@ Network Termination Equipment (NTE)@ and CPE. These devices are outside the scope of this document. Purpose This standard provides a set of definitions@ measurement methods@ configuration requirements@ and guidelines for calculating the Telecommunications Energy Efficiency Ratio (TEER) of the associated access equipment. The standard will also provide standardized definitions of access equipment interfaces. These definitions may include operational data rates and conditions to be used when calculating the TEER of any given configuration. The general test methodology used to independently verify the energy consumption used as part the TEER calculation is addressed in ATIS-0600015.
