laboratory. The supplier may also provide additional data for configurations different from

those tested by the third party test laboratory.

Telecommunications Energy Efficiency Ratio

The following guidelines will be followed when defining TEER for equipment:

• The scale will be fully defined in the supplemental standards such that typical TEER

values range from 1 to 1000.

• The higher the TEER value, the more energy efficient the equipment is compared to

other like equipment.

• The supplemental standard will define the TEER calculation details.

TEER is the ratio of useful work over energy consumed,

Application

The standards will be used to establish baselines for minimum acceptable energy efficiency

of network elements. In addition to the General Requirements, the supplemental standards

shall be used to create Telecommunication Energy Efficiency Ratios (TEER) by equipment

type.

The equipment types are currently categorized as Core, Transport, Access, CPE, and Power

Systems based on application and location in the network.

Standards Development

At the time of this issue, ATIS has several standards at various stages of development

ranging from final editing, draft for review, to draft preparation. As ATIS publishes these

and subsequent supplemental energy efficiency standards they shall be adopted first as

objectives and finally as requirements in revisions of this Technical Publication.

Energy Efficiency Report

An Energy Efficiency Report shall be included in any new product evaluation for Carrier

Grade Level 3. A sample TEER reporting form is available from ATIS-0600015.2009. In

addition to this form, data as required for the specific equipment types covered by ATIS-

0600015.01-.04 shall also be reported.
