Resource Management
RMX units that are used mainly for voice (Audio Only) conferencing can
maximize the resources utilization by designating all or almost all system
resources as voice (audio) resources.
Up to 400 (RMX 1500)/ 800 (RMX 2000 with two MPM+) or 720 (RMX
2000 with two MPMx)/1600 (RMX 4000 with four MPM+/MPMx-D)
voice participants can connect to the RMX, of which up to 400 participants
can connect using PSTN/ISDN connection.
Resource Capacity
The RMX 1500 supports only MPMx cards.
The RMX 2000 can support three card types: MPM, MPM+ and MPMx.
The RMX 4000 can support two card types: MPM+ and MPMx.
MPM+ cards offer higher capacity. Three MPM+ card assemblies are
available, MPM+ 80, MPM+ 40 and MPM+ 20, offering various port
capacities.
MPMx cards offer a high capacity similar to MPM+.
