Communication Protocol Options
The SoundStation IP 3000 - 3Com NBX 

uses the NBX protocols and can operate 

in either a shared/switched topology 

or a routed network.
When connected to the same physical 

network as the NBX Call Processor, the 

SoundStation IP 3000 - 3Com NBX will 

auto-discover the NBX Call Processor 

using the NBX protocol. 

If the NBX Call Processor is located 

on a different network segment, or if an 

NBX Call Processor can not be found, 

the SoundStation IP 3000 - 3Com NBX 

will switch to Layer 3 mode and use 

either DHCP or statically configured IP 

parameters to detect and register with the 

NBX Call Processor.
