Full title and description

Information technology — Control network protocol — Part 3: Power line channel specification. This international standard specifies the Power Line (PL) channel aspects of the Control Network Protocol (CNP), providing the physical‑layer definition and guidance needed to implement CNP communications over power line media.

Abstract

ISO/IEC 14908-3:2012 describes the complete OSI physical layer for the power line channel used with the Control Network Protocol. It defines the interface to the Medium Access Control (MAC) sublayer, parameters specific to the PL channel type, and guideline physical and electrical specifications for the power line environment to aid product development and interoperability.

Scope

The standard applies to the Power Line (PL) physical channel used with the Control Network Protocol. It covers the full OSI layer 1 specification for PL media, including the electrical and timing interfaces to the MAC sublayer, channel‑specific parameters (for example signalling, modulation and timing conventions where applicable), and recommended physical/electrical characteristics of the power line environment to support interoperable CNP implementations.

Key topics and requirements

• Definition of the PL physical‑layer functions and services required by the MAC sublayer.
• Channel parameters and signalling conventions specific to power line media.
• Electrical and physical environment guidelines for PL installations (voltages, coupling, immunity considerations).
• Interfaces and timing relationships between the physical layer and MAC sublayer.
• Normative and informative parameters to support product development and testing for interoperability.

These topics reflect the core technical content that implementers must follow to ensure compatible PL channel operation for CNP.

Typical use and users

Implementers and designers of control network devices and transceivers that use power line media; system integrators and manufacturers in building automation, industrial control and similar local area control networks; testing and certification bodies verifying conformance to the PL channel specification; standards developers and network architects designing CNP‑based solutions.
