SCTE 271 2021 PDF

This specification provides precision, sampling rate, and configuration requirements if vendors choose to measure and report voltage and/or current in hardware and software to enable advanced power sensing in cable and utility networks. Included are requirements for sensing and communicating power quality observations from both the 60/75/90 VAC quasi-square wave HFC network and the 120/240 VAC supply from the electric power grid. For systems that require remote communication of measurements, requirements for the control plane and communications security are specified. This specification does not require any particular measurements, but if supply voltage and/or current is measured, it specifies how those measurements must be made to realize the benefits described in section 1.3.
