Technical Specifications

Figure 1-1. MultiVOIP Gatekeeper

The Gatekeeper conforms to the following technical specifications.

Chassis

 6-slot PCI/ISA backplane

 SBC

 10/100Mb PCI EtherNet NIC

 One half-height 1.44Mb 3½-inch floppy disk drive

 One half-height IDE hard drive

 One 250-watt power supply

 One 32x CD-ROM Drive

 Power on/off switch on front panel with built in power LED.

 Full security locking

Power Supply

AC Input

 Power requirement: 115/230V; 7A/4A (RMS) selectable by slide switch

 Frequency: 50-60 Hz

 Efficiency: >65% @ full load, nominal line

DC Output

 Outputs: +5 @ 25A, +12 @ 10A, -5 @ 0.5A, -12 @ 0.5A

 Inrush current: <30A peak @ 115VAC, cold start at 25

 Line regulation: +/- 5% at full load for +/-5V, +/-12V, +/-10% for -12V

 Hold Time: 12ms at full load @ 115VAC

Note: 3.3 volts, DC, is available at PCI expansion slots on one side of the backplane only,

because PCI expansion cards made by some other manufacturers may require 3.3 volts. Any

such boards must be installed in the Gatekeeper on the side of the chassis where the Single-

Board Computer is located. Since there is no 3.3-volt supply on the other side of the backplane,

such PCI expansion cards will not operate properly in those positions.
