Chapter 16-Network Services
Polycom, Inc. 16-55
• Multiple Network Services are not supported with Microsoft ICE Environments in
versions prior to Version 7.8.
• Only IPv4 is supported for the definition of Multiple Network Services.
•On the RealPresence Collaboration Server (RMX) 1500, up to two Network Services, one
per LAN port, can be associated with each Media card.
•On the RealPresence Collaboration Server (RMX) 2000/RealPresence Collaboration Server
(RMX) 4000, 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, 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.
• An IP Network Service can be associated with one or several media cards.
• If more than one card is associated with the same Network Service, the system routes
the calls to the appropriate card according to resource availability.
• 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:
•Prior to Version 7.8, only one DNS server could be defined for the entire configuration
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.
