CAUTION

Power supplies used with this desktop board must be able to provide enough standby current to
support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby
current necessary to support multiple wake events from the PCI and/or USB buses exceeds power
supply capacity, the desktop board may lose register settings stored in memory.

• Requires only one call to access the computer
• Detects incoming call similarly for external and internal modems
• Requires modem interrupt be unmasked for correct operation

Wake from USB
