Enabling HD Video Switching
For the MCU to run HD Video Switching conferences the following 
criteria must be met:
The HD_THRESHOLD_BITRATE flag must be set in the System 
Configuration. The value of this flag is the system minimum threshold 
bit rate. 
The line rate selected in the conference Profile must be the same as or 
higher than that specified by the HD_THRESHOLD_BITRATE flag.
The High Definition Video Switching option must be selected in the 
The RMX 2000 must have available resources (ports).
The endpoints must support HD.
Modifying the HD Video Switching Threshold Bit Rate
To Modify the HD Video Switching Threshold:
1
Click Setup>System Configuration.
The System Flags dialog box opens.
2
Set the HD_THRESHOLD_BITRATE flag to the required line rate 
value (range 384kbps to 4Mbs, default is 768 Kbps).
3
Click OK.
The MCU must be reset the MCU for flag changes to take effect.
For more information see "System Configuration” on page
Creating a High Definition Video Switching Profile
An HD Video Switching enabled Profile must be created prior to running 
HD Video Switching conferences.
High Definition Video Switching conferences, Entry Queues and Meeting 
Rooms are created by selecting an HD Video Switching-enabled Profile 
and must be set to the same line rate as the target conference.
To connect to an HD Video Switching conference via an Entry Queue, the 
Entry Queue must be HD Video Switching enabled. It is recommended to 
use the same Profile for both the target conference and Entry Queue.
The HD_THRESHOLD_BIT RATE flag is responsible for negotiation only,
It does not guarantee that the endpoint will open an HD channel or transmit on 
an opened HD channel.
