Network Security
Network Separation
RMX 4000
On the RMX 4000 Media, Signaling and Management networks are
physically separated to provide enhanced security. In contrast to the RMX
2000, where the media, Signaling and Management use the same physical
port when there is no network separation, on the RMX 4000 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 a MPM+ 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 Intel
Processor on the MCU.
