Configuration as a PHY uses a Media Independent Interface (MII) to interface to a MAC
is common in switch applications in which the digital transceiver interfaces between the
VDSL link using the AFE and the Ethernet MAC implemented by the switch itself. The
digital transceiver acts as a standard Ethernet PHY and can connect directly to the
standard MII interface of a switch. This MII interface is compatible with the IEEE 802.3
standard.
