● On the RealPresence Collaboration Server (RMX) 2000/4000, both RTM ISDN or RTM LAN can be
used for Multiple Services configuration. However, if RTM ISDN is installed and used for Multiple
Services configuration, only one Network Service can be associated with the media card to which the
RTM/ISDN card is attached.
● On the RealPresence Collaboration Server (RMX) 1500, when Multiple Network Services option is
enabled, the two networks must differ in their subnet masks.
● On the RealPresence Collaboration Server (RMX) 1500 and 1800, LAN redundancy cannot be
enabled in parallel to Multiple Networks and the LAN_REDUNDANCY flag must be set to NO when
the Multiple Networks option is enabled.
● Participants on different networks can connect to the same conference with full audio, video and
content capabilities.
● Traffic on one network does not influence or affect the traffic on other networks connected to the same
MCU, unless they are connected to the same media card. If one network fails, it will not affect the
traffic in the other connected networks, unless they are connected to the same media card and the
card fails.
● Maximum number of services that can be defined per Collaboration Server platform:
● From Version 7.8 onwards, a DNS server can be specified for each IP Network Service and for the
Collaboration Server Management Network Service.
In the Network Services that do not include the DNS, use the IP addresses of the various devices
to define them in the Network Services.
● Participants are associated with a Network Service and use it resources as follows:
Dial-in participants - according to the network used to place the call and connect to the
Collaboration Server.
Dial-out participant - according to the Network Service selected during the participant properties
definition or during conference definition, according to the Network Service selected as default.
