P1704 - Standard for Utility Industry End Device Communications Module
This document defines the hardware physical interface and interface signals between IEEE 1703 Devices (such as IEEE 1377 meters or distribution automation devices) and IEEE 1703 communication modules. The communication modules are described as being attachable and removable to/from the IEEE 1703 Devices, and are not intended to be internal to the metering devices. Included in this standard are the physical dimensions, electrical connections, communication hardware interface signals, and module positioning which involves the secure physical mounting, weather elements, and communications propagation considerations. This standard serves as the extension of (but not limited to) IEEE 1703, MC1222, and ANSI C12.22 standards in regard to the communications module hardware interfaces, reference signals, their description and specification.
