Polycom 1500/1800/2000/4000 manual That Include ICE, Cards Up to 2 per Media Card Services

Network Security

●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:

Maximum Number of Network Services per Collaboration Server System

	Total Media	Network Services	Management	Network Services
MCU				that Include ICE
	Cards	(Up to 2 per Media Card)	Services
				(1 / Media Card)
1500	1	Up to 2	1	1
1800	3 (DSP Cards)	Up to 2
(Excluding			1	1
1800-0)
2000	2	Up to 4 when using 2 RTM LAN
		cards.
		Less when using a combination	1	2
		of RTM ISDN and RTM LAN, or
		2 RTM ISDN cards.
4000	4	Up to 8 when using 4 RTM LAN
		cards.
		Less when using up to 2 RTM	1	4
		ISDN cards and the remaining
		RTM LAN cards.

●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.
