ITU-T G.9977 PDF

This Recommendation specifies functionality of a mechanism to mitigate interference caused by in-home powerline communication (PLC) devices to an x-type digital subscriber line (xDSL) network termination (implementing transceivers in compliance with ITU-T Recommendations such as [ITU-T G.993.2] and [ITU-T G.9701]). This Recommendation addresses various in-home network types and wiring topologies.

The coordination of both the xDSL access network and in-home PLC network is facilitated by an arbitration function (AF), in order to reduce interference and optimize the performance of both networks and meet the throughput requirements to the end customer across both networks, by appropriately configuring relevant parameters of PLC devices and xDSL network termination (NT) based on a coordination policy that is usually determined and provided by the operator.
