Electricity Metering —— Data Exchange for Meter Reading, Tariff and Load Control Part 42 Physical Layer Services and Procedures for Connection-Oriented Asynchronous Data Exchange

This standard defines the physical layer services and procedures for connection-oriented asynchronous data exchange in the context of electricity metering, including data collection, billing, and load control. It outlines the specifications for the physical layer, ensuring reliable and efficient communication between devices involved in the process. The standard provides detailed descriptions of the functions, procedures, and parameters required for the physical layer implementation. It is part of a series that addresses various aspects of data exchange in electricity metering applications. The document includes information on signal characteristics, transmission media, and interface requirements. It is intended to support interoperability and standardization in the field of power metering and related data exchange processes. The standard is applicable to systems that require the exchange of metering data, billing information, and load control commands through asynchronous communication methods.
