This European Standard specifies all the information necessary to facilitate the exchange of data and control
information over the power line medium.
This European Standard establishes a minimal set of rules for compliance. It does not rule out extended
services to be provided, given that the rules are adhered to within the system. It is the intention of the
standard to permit extended services (defined by users) to coexist.
Certain aspects of the standard are defined in other documents. These documents are referenced where
relevant. In the case where a referenced standard conflicts with this European Standard, this European
Standard will prevail.
