RMX 2000 Administrator's Guide Version 7.6.1 - Polycom

Table 15-25 Maximum Number of Network Services per RMX System
RMX Platform IP Network Services
RMX 4000 Up to 4 (Up to 2 RTM ISDN cards and the
remaining RTM LAN cards)
Up to 8 (using 4 RTM LAN, less when
using up to 2 RTM ISDN cards)
Chapter 15-Network Services
• Only one DNS server can be defined for the entire configuration. It is recommended to
define it in one of the IP Network Services (signaling) and not the Management
Network to enable dialing in/out using names.
— 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 RMX.
— 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.
Resource Allocation and Capacity
Management
Services
The Video/Voice Port Configuration and the Resolution Configuration settings are configured
per MCU and affect the resource capacity of the MCU. They are reflected in the port gauges
displayed on the RMX management application’s main screen. In Multiple Networks mode,
the overall resources as configured in the Video/Voice Port Configuration are divided between
the Network Services. However, the port gauges do not reflect the resource availability per
Network Service.
Fixed and Flexible Resource Allocation Mode
On RMX 2000/4000 resources are divided between services according to the number of
media cards associated with each service and the card assembly type (for example, MPM+40
vs. MPM+80). If two identical media cards are installed in the system and each card is
assigned to a different Network Service, the resources are split between the services.
If two cards are installed but each card is of different assembly type, the resources are
allocated according to the card capacity ratio. For example, in a system with one MPM+40
and one MPM+80, the capacity ratio is 1 to 2, therefore a third of the resources will be
assigned to the network service associated with MPM+40 and two thirds will be assigned to
the Network Service associated with MPM+80.
On RMX 1500 and RMX 2000/4000 with two Network Services associated with one media
card, the resources of the two Network Services associated with one media card are not split
between the network services. In such a case, resources are used per their availability by
both Network Services equally.
On RMX 2000, if RTM ISDN is installed and used for Multiple Services configuration, only
one Network Service can be defined per media card.
In Fixed Resource Allocation Mode if the resources cannot be divided into whole numbers,
they will be rounded up to the nearest whole number, assigning that resource to the Network
Service with the higher capacity (i.e. more media cards or media cards with higher capacity
due to a different card assembly).
