Polycom 7000 manual Cascade for bandwidth

Conference Manager Configuration

Field	Description
Cascade for bandwidth	Enables conferences using this template to span Polycom MCUs to conserve
	network bandwidth.
	Cascading for bandwidth requires site topology information, which the
	Polycom RealPresence DMA system can get from a Polycom RealPresence
	Resource Manager system (see RealPresence Resource Manager
	Integration) or you can create (see Site Topology).
	This option and Cascade for size are mutually exclusive. See About
	Cascading for more information about enabling cascading of conferences.
Cascade for size	Enables conferences using this template to span Polycom MCUs to achieve
	conference sizes larger than a single MCU can accommodate.
	This option and Cascade for bandwidth are mutually exclusive. See About
	Cascading for more information about enabling cascading of conferences.
Video switching (VSW)	Enables a special conferencing mode that provides HD video while using
	MCU resources more efficiently. All participants see the current speaker full
	screen (the current speaker sees the previous speaker).
	If this mode is enabled:
	• The minimum line rate available is 768 kbps (except for SD resolution,
	available only on v7 and newer Polycom MCUs with MPM+ or MPMx
	cards).
	• All endpoints must connect at the same line rate, and those that don’t
	support the specified line rate are connected in voice-only mode.
	• The video clarity, layout, and skins settings are not available.
	• LPR is automatically turned off, but can be turned back on.
	If this option is off, conferences using this template are in Continuous
	Presence (CP) mode, in which the MCU selects the best video protocol,
	resolution, and frame rate for each endpoint according to its capabilities.
H.264 high profile	Sets a VSW conference to use Polycom’s bandwidth-conserving H.264 High
	Profile codec (previously supported only in continuous presence mode).
	If this is selected, all endpoints in the conference must support High Profile.
	Endpoints not connecting at the conference's exact line rate and resolution
	are connected in audio-only mode. Available only on v7.6 and newer Polycom
	MCUs with MPMx cards.
Resolution	Available only if Video switching is selected. Offers various resolution
	settings, some of which are only available on Polycom MCUs with MPM+,
	MPMx, or MPMRx cards.
Line rate	The maximum bit rate at which endpoints can connect to conferences using
	this template.
	If Video switching is selected, the minimum line rate is 768 kbps (except for
	SD resolution, available only on v7 and newer Polycom MCUs with MPM+ or
	MPMx cards).
