Ethernet CIRCUIT

The Ethernet IC (IC2) is used for the Ethernet interface.
It is connected from IC2 to the Ethernet port (JK1) through a transformer and so is isolated.
Also, Ethernet port (JK1) gets power from the Ethernet line for PoE (Power-over-Ethernet) as shown below.
It is connected between IC2 and the VoIP (IC1) by high-speed bus called MII (Management Independent Interface) bus
operating with 25MHz.
