This specification contains all the information necessary to facilitate the exchange of data and control information over the power line medium within a home. The document is divided into five sections (1 - 5): 1. An introduction to the specification. 2. A general description of the power line network that is likely to exist in home environments. 3. The specifications of the allowed topology and configuration rules for constructing EIA-709.2 compliant networks in homes. 4. A specification of the EIA-709.2 physical medium. This section covers frequency allocation, physical and electrical specification of the medium, connectors, environmental requirements, and installation considerations. 5. The physical layer specification of an EIA-709.2 compliant node. This section covers the interface to the higher ISO layers, control channel signal characteristics, encoding, transmitter and receiver and signal coupling characteristics.
