Dear ENERGY STAR® Telephony Partner or Other Interested Stakeholder:With this letter, the U.S. Environmental Protection Agency (EPA) is launching the data assembly efforts tosupport the development of the Draft 1 Version 3.0 ENERGY STAR specification for Telephony, based on
the attached Draft 2 ENERGY STAR Test Method. EPA will host a stakeholder webinar to discuss theTest Method and questions regarding the data assembly on Tuesday, December 18, 2012, from 2 to
4 pm Eastern Time and invites stakeholders to submit written comments by December 28, 2012.
Although the Test Method is still under development, major changes are not expected.
The latest changes to the Test Method were informed by feedback on the previous draft and participationin the webinar held on June 19, 2012, which informed the latest changes to the Test Method.
Brief Summary of Modifications to the Test Method:•Excluded Telephones capable of transmitting full-motion video from the scope of the Version 3.0
specification.

•Revised and reviewed Section 3 B) Operational Modes to harmonize terms with IEC 62542,
Standardization of Environmental Aspects, where possible and avoid confusion with existing
industry terms.

•

Updated the Power over Ethernet (PoE) definition to reference the recently finalized standard
IEEE 802.3-2012 and include only methods covered under its scope (e.g., “4-pair” (Mode A + B)
powering schemes are prohibited).

•

Updated the PoE input voltage requirements to allow for the use of both Type 1 and Type 2
Power Sourcing Equipment (PSE) as well as lower voltages during detection and classification.

•Clarified the definition of Unit Under Test (UUT) in situations where a Cordless Telephone ispackaged with Additional Handset, by specifying their operation and placement during testing.

•Modified the Partial On Mode power measurement to ensure batteries are fully charged and toaccount for charging cycles.

Telephony Data Assembly – Submit to EPA by February 28, 2013
EPA will develop proposed ENERGY STAR levels based on data developed using this Draft 2 Test
Method and submitted via the Test Reporting Template. Products may be tested by in-house laboratories
and do not require third-party verification. Please submit all data to EPA via e-mail totelephony@energystar.gov by February 28, 2013.
Timeline and Next Steps
EPA will host a stakeholder webinar on Tuesday, December 18, 2012, from 2 to 4 pm Eastern Time todiscuss revisions to the test method and address any data assembly questions. To RSVP, please e-mailtelephony@energystar.gov. As always, the exchange of ideas and information among EPA, industry, and1

other interested parties is critical to the success of ENERGY STAR. Stakeholders are strongly
encouraged to e-mail feedback on the Draft 2 Version 1.0 Test Method to telephony@energystar.gov byDecember 28, 2012.
