Polycom RealPresence Collaboration Server (RMX) 1500/2000/4000 Administrator’s Guide
9-2 Polycom, Inc.
—RealPresence Collaboration Server (RMX) 4000 MPMx-D Mode: 1440 (180 video).
• System resources are calculated according to the RMX’s license. For more information
see "Video/Voice Port Configuration” on page 21-10.
• System resource availability is partially checked when reservations are created:
—If a conference duration extension request is received from an ongoing conference,
the request is rejected if it would cause a resource conflict.
—If several reservations are scheduled to be activated at the same time and there are
not enough resources for all participants to be connected:
• The conferences are activated.
• Participants are connected to all the ongoing conferences until all system
resources are used up.
• If sufficient resources are not available in the system and a scheduled Reservation cannot
be activated, the Reservation is deleted from the schedule.
• Resources for Reservations are calculated using the Reserve Resources for Audio/Video
Participants fields of the New Reservation dialog box. For more information see "New
Reservation – Reserved Resources” on page 9-9.
• Resources are reserved for participants at the highest video resolution supported by the
Line Rate specified in the conference Profile and up to the maximum system video
resolution specified by the Resolution Configuration dialog box.
If the RMX is in MPM+ or MPMx Mode and Fixed Capacity Mode is selected, the number
of resources allocated to this type of video participant (CIF, SD, HD) is also checked. If
resource deficiencies are found an error message is displayed.
• When a new Reservation is created in the Reservation Calendar, the effect of the new
Reservation (including its recurrences) on available resources is checked. If resource
deficiencies are found an error message is displayed.
Defined dial-in or dial-out participants, Meeting Rooms, Entry Queues and new
connections to Ongoing conferences are not included in the resources calculation.

Reservations

•A Reservation that has been activated and becomes an ongoing conference is deleted
from the Reservation Calendar list.
• The maximum number of concurrent reservations is 80. Reservations with durations
that overlap (for any amount of time) are considered to be concurrent.
• System resource availability is partially checked when reservations are created:
—If a conference duration extension request is received from an ongoing conference,
the request is rejected if it would cause a resource conflict.
—If several reservations are scheduled to be activated at the same time and there are
not enough resources for all participants to be connected:
• The conferences are activated.
• Participants are connected to all the ongoing conferences until all system
resources are used up.
•A scheduled Reservation cannot be activated and is deleted from the schedule if an
Ongoing conference has the same Numeric ID.
From Version 7.1, MPM media cards are not supported.
