System security can be enhanced by separating the Media, Signaling and Management
Networks.
On the RMX 1500 and 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 MCU.
On the 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.
