Function Blocks Description
PHY (Physical Layer Device - OSI
Layer 1)
Completely standardized physical layer device for the
functions of each device in the network.
EEPROM Stores the MAC address.
The physical device layer, the lowest layer of the OSI reference model, refers to
the physical components of the network: cables, connectors, etc. OSI, the
Operating Standard Interface, is a framework upon which networking standards are
arranged. It is commonly diagramed as a layered pyramid with the physical layer,
Layer 1, on the bottom of the pyramid, and layer 7, the application layer, at the top.
