The ConneXtions software requires a dedicated computer system that is
running Windows 2000. The system hardware must be certified by
Microsoft. The installation software checks for the presence of Windows
2000 and then loads the correct packet driver from the NBX Resource
Pack CD.
Although the ConneXtions software requires little disk storage,
processing and memory requirements are crucial, and you might need
multiple gateways. Microsoft server licenses do not apply because no
additional operating system logons are involved.

Compatibility List.
Processor, Memory, and Bandwidth Requirements
Each G.711 call needs about 50 MHz on a Pentium II or 20 Mhz on a
Pentium III. Each G.723 call needs about 128 MHz on a Pentium II or 75
Mhz on a Pentium III. These speed requirements increase directly with the
number of ports. The IP router bandwidth requirements also increase
directly with the number of ports.
The bandwidth requirements for a Pentium II and a Pentium III are
identical.
Table 88 shows the speed and bandwidth requirements for different
numbers of ports. It assumes that each packet carries a 50-byte overhead.
