Configuring the RMX - Serial Gateway Connection

Configuring the connection between the Serial Gateway and the RMX consists of the
following procedures:
Polycom, Inc.
— An RMX 4000 with 4 RTM-LAN cards installed can support up to 7 Serial Gateways.
(If 8 Serial Gateways are deployed, connection to an external network is not
possible.)
A Serial Gateway can be associated with only one Network Service. When configuring
multiple Serial Gateways, each Serial Gateway can be associated with only one Network
Service. This requires the configuration of Multiple Network Services on the RMX.
For more information see the RealPresence Collaboration Server (RMX) 1500/2000/4000
Administrator's Guide, "Multiple Network Services" on page 16-49.
Although the Media and Signaling Network Service on the RMX can be configured for
IPv6 addressing, the Network Service assigned to the Serial Gateway can only support
IPv4 addressing.
The following System Flags must be set to YES:
— ULTRA_SECURE_MODE
— V35_ULTRA_SECURED_SUPPORT
When using version prior to Version 7.5.2.J, when connecting a Serial Gateway to an
RMX 2000:
— It is essential that an RTM LAN card is installed.
— The Serial Gateway must be physically connected to a
RTM LAN card, LAN 1 port.
— The SEPARATE_MANAGEMENT_NETWORK System Flag must be set to YES.
When using Version 7.5.2.J, a Serial Gateway can be connected directly to any available
RTM-LAN port on the RMX that is associated with a Network Service.
If two Serial Gateways are connected to the same RTM-LAN card using both LAN 1 and LAN 2,
the resources of the Media Card are not available to external IP networks.
Where possible, it is advisable to connect only one Serial Gateway per RTM-LAN card.
The MULTIPLE_SERVICES System Flag must be set to NO.
If Content is to be shared the conference Profile should have Content Protocol set to H.263.
When the RMX is in Ultra Secure Mode, it requires that the Serial Gateway be in Maximum
Security Mode. For more information see the RMX 1500/2000/4000 Deployment Guide for
Maximum Security Environments, "Serial Gateway S4GW - Maximum Security Mode" on
page 5-13.
H.323 connections to the RMX are 1024-bit encrypted TLS.
RTP traffic between the RMX and the Serial Gateway are not encrypted.
If the certificates installed on the Serial Gateway and the RMX are signed by the same
Certificate Authority, that Certificate Authority must be trusted. If the certificate installed
on the Serial Gateway was issued by a different Certificate Authority to the one that issued
the RMX certificate, the Certificate Authority trust that signed the Serial Gateway
certificate must be added to the Trusted Certificate Repository on the workstation.
An RTM LAN card must be installed in the RMX2000 or RMX4000 if an RMX Serial
Gateway S4GW is to be directly connected to the RMX.
