Installation Requirements 391
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 multiprocessor (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 drive for loading ConneXtions software from the
NBX Resource Pack CD.
■ 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
can also be used to communicate with the IP router. This single NIC
