The U.S. Environmental Protection Agency (EPA) recently published the third draft of its ENERGY STAR® Small Networking Equipment spec (v1). The program covers non-rack-mounted versions of broadband access devices (modems, integrated access devices (IADs), and optical network termination devices) and local network equipment (access points, routers, and switches).
I wrote about draft 2 of the spec last fall (see: Networking with a Little Less Power Consumption?). The main changes in latest draft are revisions in base power allowances.
Table 1: Base Power Allowances
|Product Type||P_BASE (watts)
|Broadband Modem – Cable||5.7*|
|Broadband Modem – ADSL||4.0|
|Broadband Modem – ONT||4.4†|
|IAD – Cable||6.1*|
|IAD – ADSL||5.5|
|IAD – VDSL||7.5‡|

‡ EPA removed the Broadband Modem – VDSL product category after deciding that their features called for them to be placed in the IAD -VDSL category. The result is a lower base value in the IAD – VDSL category.
Other changes include:
- The addition of a telephony adder in order to support 911 capabilities in cable modem and cable IAD products.
- A proposal that products with both ASDL and VSDL functionality be tested using VDSL connections and meet the VSDL base power allowance.
