Central Sites
Each side of the Central Controller includes the CallRouter, Logger, and Network 
Interface Controller (NIC). These may be on three separate nodes, two nodes, or 
a single node. Although the NICs are indicated as separate nodes for clarity, in 
fact a NIC is implemented as a process within the CallRouter node. The two sides 
of the Central Controller may be at two different central sites as shown in
