Field	Description
Conference mode	One of the following:
	• AVC only — Standard videoconferencing mode
	supporting the H.264 Advanced Video Coding
	(AVC) compression standard. In an AVC
	conference, the MCU transcodes the video stream
	to each device in the conference to provide an
	optimal experience, based on its capabilities.
	This is the only mode that supports the use of RMX
	profiles, third-party and legacy endpoints, and
	Codian and legacy RMX MCUs.
	• SVC only — Videoconferencing mode supporting
	the Annex G extension of the H.264 standard,
	known as H.264 Scalable Video Coding (SVC). An
	SVC video stream consists of a base layer that
	encodes the lowest available quality representation
	plus optional enhancement layers that each provide
	an additional quality improvement.
	The number of enhancement layers and the
	number of participants’ video included in a video
	stream to a device can be tailored to fit the
	bandwidth available and device capabilities.
	SVC conferencing is only possible with Polycom
	MCUs and endpoints that support H.264 SVC.
	Selecting this setting disables most of the other
	template settings.
	See “SVC Conferencing Support” on page 4.
RMX General Settings
Use existing profile	Links this template to the RMX profile selected in the list
	below.
	For most purposes, we recommend leaving this box
	unchecked and specifying conference properties
	directly. See “Conference Templates” on page 195.
RMX profile name	Identifies the RMX profile to which this template is
	linked. The list contains the names of all the profiles
	available on the currently connected MCUs. If a profile
	is only available on some of the connected MCUs, its
	entry shows how many of the MCUs have that profile
	(for instance, 2 of 3).
	The system will put conferences using this template on
	the least used RMX MCU that has this profile. If there
	are none, it selects the least-used MCU and either uses
	the Codian-specific settings (if it selected a Cisco
	Codian MCU) or falls back to the default conference
	template (if it selected a Polycom RMX MCU).
