Field	Description
Enable for conference	Makes the MCU available as a conferencing resource
rooms	for the Polycom DMA system’s Conference Manager.
	Up to 64 MCUs can be enabled for conference rooms.
	Caution: Before adding an MCU to the DMA system’s
	conferencing resources, make sure that MCU isn’t
	already a RealPresence Resource Manager system
	conferencing resource. The RealPresence Resource
	Manager system must have exclusive use of any MCUs
	on which it directly schedules conferences.
Enable gateway profiles	Makes the MCU available for selection as an ISDN
	gateway device and enables the Gateway Profiles tab
	for configuring gateway session profiles.
	Gateway session profiles indicate to the MCU the
	bandwidth parameters to be used for the ISDN
	connection. They can be used for:
	• ISDN gateway calls to the MCU’s direct dial-in
	prefix. In this case, the caller specifies the session
	profile prefix in the dial string:
	<direct dial-in prefix><session profile
	prefix><delimiter><E.164 number>
	• Calls to simplified ISDN gateway dialing prefixes
	(see “Add Simplified ISDN Gateway Dialing Prefix
	Dialog Box” on page 277). In this case, the DMA
	system selects the MCU/gateway and its session
	profile. See “ISDN Gateway Selection Process” on
	page 147.
Class of service	Select to specify the default class of service and the bit
	rate limits for this MCU.
	If specified, calls to the MCU use its class of service or
	the calling endpoint’s, whichever is better.
Maximum bit rate (kbps)	Select the maximum bit rate for calls to this MCU.
Minimum downspeed bit	Select the minimum bit rate to which calls to this MCU
rate (kbps)	can be downspeeded to manage bandwidth. If this
	minimum isn’t available, the call is dropped.
	The minimum that applies to a call is the higher of the
	MCU’s and the calling endpoint’s.
Permanent	Prevents the MCU’s registration with the Call Server
	from ever expiring. For MCUs, this option should always
	be selected (the default).
