1.3 Modem Wake Up

The Modem Wake Up discussed here is to wakeup from true power off (identified

by fan of power supply is off), This mainboard still supports traditional green PC

suspend mode but it is not discussed here.

With the help ATX soft power On/Off, it is possible to have system totally power

off (The traditional suspend mode of power management function does not really

turn off the system power supply), and wakeup to automatically answer a phone

call such as answering machine or to send/receive fax. You may identify the true

power off by checking fan of your power supply. Both external box modem and

internal modem card can be used to support Modem Wake Up, but if you use

external modem, you have to keep the box modem always power-on. AOpen

AX5T/AX58 and internal modem card implement special circuit (patent applied)

and make sure the modem card works properly without any power. We

recommend you choose AOpen modem card (F56 or MP56) for Modem Wake

Up applications.
