Field	Description
Cascaded conference	Enables conferences using this template to span RMX
	MCUs.
	Cascading requires site topology information, which the
	Polycom DMA system can get from a Polycom
	RealPresence Resource Manager or CMA system (see
	“Resource Management System Integration” on
	page 185) or you can create (see “Site Topology” on
	page 283).
	See “About Cascading” on page 198 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 RMX v7 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 RMX
	v7.6 or later MCUs with MPMx cards.
