DMA Operations Guide MCUs

Note

MCU pools and pool orders are not used to select an ISDN gateway for simplified gateway dialing. See “ISDN Gateway Selection Process” on page 147.

When a Polycom RMX MCU is functioning as an ISDN gateway, each call through the gateway consumes two ports, one for the ISDN side and one for the H.323 side. The ports used for gateway calls aren’t available for conferences, so gateway operations may significantly reduce the available conferencing resources.

The following table describes the fields in the dialog box.

Table 6-3Add MCU dialog box

Field	Description
External MCU
Name	Name for the MCU (up to 32 characters).
Type	Lists the types of MCUs the system supports. Must be
	set to the correct MCU type in order for the DMA system
	to be able to connect to it.
Management IP	IP address for logging into the MCU (to use it as a
address	conferencing resource).
Admin user ID	Administrative user ID with which the Polycom DMA
	system can log into the MCU.
	For a maximum security environment, this must be a
	machine account created on the RMX MCU. Note that
	the RMX MCU uses case-sensitive machine names
	(and thus FQDNs) when creating machine accounts.
Password	Password for the administrative user ID.
Video ports reserved for	The number of video ports on this MCU that are
CMA system	off-limits to the Polycom DMA system.
	Set this to the number of ports you want to reserve for
	your Polycom CMA system to use for scheduled
	conferences (requires RMX v6.0 or later).
	Note: This feature is not for use with a Polycom
	RealPresence Resource Manager system. The
	RealPresence Resource Manager system must have
	exclusive use of any MCUs on which it directly
	schedules conferences. Those MCUs should not be
	added to the DMA system’s conferencing resources.
