Installation Requirements 417
Table 79 lists the theoretical maximum number of ports that typical
Pentium processors can handle.
The maximum number of ports can be limited by the number of licenses.
If your port processing requirements exceed the capacity of a single
processor, ConneXtions software supports either multi-processor (dual
and quad Pentium processors) or multiple gateway solutions. A Windows
2000 or Windows NT system that uses a dual 800 MHz Pentium
processor achieves the same result.
Other System Requirements
Each H.323 port requires 6 Mb of memory. 3Com recommends a PC with
at least 128 Mb of memory. Disk storage requirements are minimal. In
addition to memory and disk storage, the operating system needs:
■
A compact disk for loading ConneXtions software.
■
A 3Com Network Interface Card for connecting to the NBX LAN
(10BASE-T or 100BASE-T).
■
A 3Com Network Interface Card for connecting to a separate firewall
or router (optional).
The Call Processor coordinates its activities with the gateway through
a Network Interface Card (NIC) in that gateway system. The same NIC
