On the RealPresence Collaboration Server (RMX) 1500 and RealPresence Collaboration 

Server (RMX) 4000, Media, Signaling and Management Networks are physically separated to 

provide enhanced security. The IP Network Service and the Default Management Network have 

been logically and physically separated from each other. In the IP Network Service each IP 

address is assigned a physical port and media (RTP) inputs are routed directly to an MPM+ 

or MPMx card. This provides for a more secure network with greater bandwidth as each 

media card has its own dedicated port. All signaling communications are processed on a 

single stack of the processor in the RMX.

On the RealPresence Collaboration Server (RMX) 2000 a RTM LAN or RTM ISDN card is 

required to enable the separation between the networks. By defining Multiple Network 

Services, a separate network can be defined for each media card installed in the system.

Media, signaling and management networks can be physically separated on the RMX 

system to provide enhanced security. This addresses the requirement in an organization 

that different groups of participants be supported on different networks. For example, some 

participants may be internal to the organization while others are external.
Up to eight media and signaling networks can be defined for the RealPresence 

Collaboration Server (RMX) 4000, or four for the RealPresence Collaboration Server (RMX) 

2000 and two for the RealPresence Collaboration Server (RMX) 1500. Multiple IP Network 

Services can be defined, or up to two (RealPresence Collaboration Server (RMX) 1500)for 

each media and signaling network connected to the RMX. The networks can be connected to 

one or several Media cards in the RMX unit.
The Management Network is logically and physically separated from the media and signaling 

networks. There can be one Management Network defined per RMX system.
Each conference on the RMX can host participants from the different IP Network networks 

simultaneously.
The following figure shows the network topology with three different media and signaling 

networks and one Management network connected to the RealPresence Collaboration 

Server (RMX) 4000.
