F.4 POWER MANAGEMENT
The modem supports both APM and ACPI power management environments using methods
defined in the PCI 2.2 specification.
F.4.1 APM ENVIRONMENT
In the APM environment, the modem will be placed in Standby (as the result of either a user-
initiated action or by OS timer) unless the modem is online or transferring data. If a thermal
shutdown condition occurs, then the modem will be forced into Standby regardless of the
operational state.
F.4.2 ACPI ENVIRONMENT
The modem supports the ACPI power management environment and is compliant with PCI
specification 2.2 (PME- signaling). The card can provide system wake-up from a ring condition .
F.5 PROGRAMMING
The Compaq/Lucent V.90 56K PCI Modem card is a “controllerless” modem, meaning that all
operating parameters are controlled by the modem driver. Modem updates (if any) will be
facilitated only through the driver. Flash ROM is not involved. The modem is identified on the PCI
bus with the following values:
Vender ID (PCI Configuration space address 00h): 11C1h
Device ID (PCI Configuration space address 02h): 0441h
F.6 CONNECTOR
The card includes an RJ-11 connector for connection to an analog phone line. The signal is carried
on the two center conductors.
