Add MCU Dialog
Lets you add an MCU, gateway, or combination of the two to the pool of devices available to the Polycom 
RealPresence DMA system. 
The following table describes the fields in the dialog. 
Note: MCU support
The Polycom RealPresence DMA system supports the use of Cisco Codian 4200, 4500, and MSE 
8000 series MCUs as part of the Conference Manager’s conferencing resource pool, but their Media 
Port Reservation feature is not supported. This feature must be set to Disabled on Cisco Codian 
MCUs in order to use them as part of the Conference Manager’s conferencing resource pool. 
The Polycom RealPresence DMA system supports the use of Polycom MGC MCUs, but not as part of 
the Conference Manager’s conferencing resource pool. They can register with the Call Server as 
standalone MCUs (dialed by IP or prefix) and/or ISDN gateways. Their model designation is Polycom 
MGC gateway
, even if being used as standalone MCUs. 
Note: MCUs and ISDN gateway selection
MCU pools and pool orders are not used to select an ISDN gateway for simplified gateway dialing. 
See 
When a Polycom 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.
Note: Resource usage reporting
The RealPresence DMA system reports port numbers based on resource usage for CIF calls. Version 
8.1 and later Polycom MCUs report port numbers based on resource usage for HD720p30 calls. In 
general, 3 CIF = 1 HD720p30, but it varies depending on bridge/card type and other factors. 
See your Polycom RealPresence Collaboration Server or RMX system documentation for more 
detailed information about resource usage.
Field 
Description
External MCU 
Name 
Name for the MCU (up to 32 characters; must not include any of the following: 
, " ; ? : = *). 
Type 
Lists the types of MCUs the system supports. Must be set to the correct MCU 
type in order for the RealPresence DMA system to be able to connect to it. 
For an MGC MCU, this must be set to Polycom MGC gateway, even if it’s 
being used as a standalone MCU.
