With short copper loops required by G.fast Distribution Point Units (DPUs) that push the deployment of the DPU/MDUs closer to the customer premise, local power and forward power may not be viable to cost or location. To power the DPU, power will come from the customer premises location over the copper pair; this is referred to as Reverse Power Feed (RPF).
This document specifies tests for the RPF functions of a DPU and the customer premises’ Power Supply Equipment (PSE) either as a stand-alone device or as a function integrated in a G.fast Network Termination.
Issue 3 will define a set of RPF-over-coax functional and safety test cases for the Power Source Equipment (PSE) implemented according to ETSI specification TS 101 548-2, either as a stand-alone device or as a function integrated in the G.fast (G.9700 and G.9701) network termination, and reversely powered DPU implementations. It will include also RPF integrated in G.hn Access and MoCA Access network termination.
