Physical Layer
The Physical Layer consists of the transceiver, connector, mis-wiring protection
circuitry, regulator, and optional optical isolation.
shows the block diagram
of the Physical Layer. In this section, the transceiver, mis-wiring protection (MWP),
and optional isolation are explained. For more information on connectors, refer to
