A digital transceiver configured as a PHY that 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.
