1.2 Zero Voltage Wake on Modem
The Wake on Modem discussed here is to wakeup from true power off
(identified by fan of power supply is off), This motherboard 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 0V Wake On Modem,
but if you use external modem, you have to keep the box modem always
power-on. AOpen MX59 Pro 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 (For example, FM56-P,
FM56-H, etc.) for 0V Wake On Modem applications.
