Chapter 4 - Setting Up Conferences
4-82
Resource Force
The system automatically selects the cards that will run the conference
according to the conference type and MCU configuration. Audio Only
conferences are always run on the Audio+ card. IVR-enabled Video
conferences are run on the Audio+ card. If the video services are enabled in
the IVR Service, the conference will also run on the Video+ card. Standard
Video conferences (Video Switching and Continuous Presence - Classic) are
run on the Standard Audio card and Standard Video card (Continuous
Presence - Classic). If Continuous Presence - Quad Views is selected, the
conference will run on the Audio+ and Video+ cards.
You can change the automatic selection of the MCU resources to run the
conference. If your MCU contains both standard Audio and Audio+ cards you
can select the Audio card type to run the conference. For example, if you want
to ensure that the Standard Audio card is used to run the conference, to save
Audio+ resources, you can select it in this dialog box. You can also select the
Video card to run the conference.
Manually selecting the cards that will handle the conference allows you to
optimize the system resources when using standard Audio and Video cards
that may be vulnerable to fragmentation. For example, the MCU includes two
video cards (six participants each), and you want to schedule four
conferences; two conferences with two participants and two conferences with
four participants. When running these conferences, the system assigns the
first two conferences (with two participants each) to the same Video card,
while the third conference (with four participants) is assigned to another
video card. This results in insufficient resources for the fourth conference,
since the same card must handle all four participants. Using the Resource
Force tab, you can place the first two conferences (with two participants
each) on different video cards, saving the resources for the other two
conferences (with four participants each).
