1.2.1 PLC PHY Coupling Service
The PLC PHY Coupling service can be used in conjuction with a PLC Driver (PHY or G3 MAC RT) to facilitate the configuration of the PLC Transmission Coupling PHY parameters (PIBs).
If the application/middleware using the PLC Driver does not need to perform PLC transmissions, e.g. PHY sniffer, this service is not needed.
