Zero Voltage Wake On Modem - AOpen AX3L User Manual

Overview

1.3 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 Wake
on Modem, but if you use external modem, you have to keep the box modem
always power-on. AOpen AX3L and internal modem card implement special
circuit (patent applied) and make sure the modem card works properly without
any power. We recommend choosing AOpen modem card (MP56) for Wake
on Modem applications.
