20 MultiVOIP Gatekeeper User Guide
Introduction
This chapter introduces some of the features of the Multi-Tech Single Board Computer (or SBC), Model
IPC-551, used in the Gatekeeper. Further details can be found in Appendixes A, B, and C.
About the SBC
The IPC-551 SBC is a full size plug-in PC board with PCI bus architecture, a 233 MHz Intel Pentium
processor with MMX, 256 MB of dynamic random access memory (DRAM), Award PnP flash ROM BIOS,
a watchdog timer, and a Green PC function that enables the system to operate at a decreased power
level after it senses a period of inactivity.
The memory interface on the SBC consists of four 72-pin single in-line memory module (SIMM) sockets
(two double DRAM banks) that can be used to configure memories ranging from 8MB to 256 MB.
(Details are provided in Appendix C.) The 256 MB memory supplied with each Gatekeeper consists of
four 64 MB memory modules.
The system BIOS and VGA BIOS on the SBC can be updated as necessary using the Awdflash.exe
program provided on the system CD-ROM. (Details are provided in Appendix C.)
A watchdog timer (WDT) is provided on the SBC in case your system configuration requires that the
Gatekeeper be remotely rebooted from time to time. Setup instructions for the WDT are also provided
in Appendix C.)
The default condition for the Green PC function on the SBC board is Off. When activated, however,
the green function slows down the Gatekeeper and shuts down certain computer functions in order to
reduce power consumption. The three reduced-power operating modes built into the green function
are: CPU Doze mode, System Standby mode, and System Suspend mode. See Appendix C for further
details concerning the Green PC function.
