This Power Supply Circuit supports the power supply through an Ethernet line called PoE (Powerover Ethernet) as well as the input
from a regular AC adapter.

In addition, there is a battery backup circuit for the preservation of the Call Log Data, the telephone book, and time at the power-off.

The power supply is as follows;

Reset Signal is output from IC109 and input IC101,IC102 and IC410.
After IC101 is started, execute the reset cancellation on the peripheral.

It is connected from IC505 to the Ethernet port (CN502) through a transformer and so is isolated.
Also, LAN port (CN502) gets power from the Ethernet line for PoE (Power over Ethernet) as shown below.It is connected between
IC505 and the VoIP (IC101) by high-speed bus called MII (Media Independent Interface) bus operating with 25 MHz.
