It is recommend to set the endpoint to Motion to ensure the transmission of the higher frame rates of 25fps/30fps to 

the 

Collaboration Server.

‡ MXP 990/3000 endpoints transmit 576x448 pixels. Other MXP endpoints may transmit other resolutions 
eg. CIF. 

Sharing and receiving Content is supported.

Bandwidth allocated to the Content channel during Content sharing may cause the video resolution to be 
decreased as from w448p to w288p.

When Content sharing stops and the full bandwidth becomes available, video resumes at the previous 
w448p resolution.

For more information see the 

.

If there is Packet Loss in the network and Dynamic Bandwidth Allocation (DBA) is activated, allocating 
bandwidth for Lost Packet Recovery, video resolution decreases from w448p to w288p. 

When Packet Loss ceases and DBA no longer needs to allocate bandwidth for Lost Packet Recovery, the 
full bandwidth becomes available and video resumes at the previous w448p resolution.

For more information see the 

w448p resolution support for Tandberg endpoints requires setting of the following entities:

● Tandberg endpoint 
● Collaboration Server flags 
● Collaboration Server Conference Profile
