Appendix F Compaq/Lucent V.90 56K PCI Modem

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.
