Polycom 1500/1800/2000/4000 manual Resource Optimized, Video Quality Optimized

		Defining AVC-Based Conference Profiles
New AVC CP Profile - Advanced Parameters
Field/Option	Description
TIP Compatibility	Select the TIP Compatibility mode when implementing a Collaboration Server
	and Cisco Telepresence Systems (CTS) Integration solution. The TIP
	Compatibility mode affects the user video and content experience.
	The following TIP Compatibility modes are available:
	•	None
	•	Prefer TIP
	From Version 8.1.1, Polycom endpoints can also connect to Entry Queues,
	Meeting Rooms and conferences using the TIP protocol.
	The connection of the Polycom endpoints with TIP protocol to a TIP Compatible
	Entry Queues, Meeting Rooms and conferences using the TIP protocol is
	enabled when the Polycom endpoints are registered to the CUCM and the
	Prefer TIP option is selected in the conference Profile.
	When the Prefer TIP option is selected, conferencing entities can include
	endpoints connected using all protocols, including TIP and SIP protocols.
	When Prefer TIP is selected, Gathering Settings, content settings, Message
	Overlay, Site Names and Network Indication(s) cannot be enabled.
	Note: If an option other than None is selected in this field, the Gathering
	Settings options are disabled.
	For more information, see .
Enable FECC	This option is enabled by default, allowing participants in the conference to
	control the zoom and PAN of other endpoints in the conference via the FECC
	channel. Clear this check box to disable this option for all conference
	participants.
FW NAT Keep Alive	The MCU can be configured to send a FW NAT Keep Alive message at specific
	Intervals for the RTP, UDP and BFCP channels.
	For more information see FW (Firewall) NAT Keep Alive.
Interval	If needed, modify the NAT Keep Alive Interval field within the range of 1 - 86400
	seconds. For more information see FW (Firewall) NAT Keep Alive.
MS AV MCU Cascade	This enables you to set Cascade Mode as either Resource Optimized or Video
Mode	Optimized.
	•	Resource Optimized
		System resource usage is optimized by allowing high resolution connections
		only at high line rates and may result in lower video resolutions for some line
		rates. This option allows you to save MCU resources and increase the
		number of participant connections.
	•	Video Quality Optimized
		Video is optimized through higher resolution connections at lower line rates
		increasing the resource usage at lower line rates. This may decrease the
		number of participant connections.
