Number of Sites in Call Max Speed for Each Site
7 (RealPresence Group 700 only) 1024 kbps
8 (RealPresence Group 700 only) 832 kbps
These values do not apply when the Microsoft Skype Interoperability option is enabled. When this option
is enabled, all calls are CCCP calls and are capped at 1920 kbps due to ICE restrictions.
High-Profile Call Speeds and Resolutions
The following table includes the H.264 high-profile resolutions and frame rates sent in calls between two
RealPresence Group Series systems.
Resolutions and frame rates are based on the call speed and the Optimized for setting of your video
input.
Due to the complexities of system capabilities and the call types and scenarios in your environment, it
isn’t possible to provide the resolutions and frame rates for calls between a system and a different type of
endpoint or multipoint resource. The systems attempt to provide the highest resolutions and best frame
rates in all types of calls.
The values for sharpness and motion are the same from 2 MB to 6 MB for systems that support higher
call speeds. The difference between NTSC and PAL cameras is how frame rates are calculated:
• NTSC 60 fps equals PAL 50 fps
• NTSC 30 fps equals PAL 25 fps
The following table shows the resolutions for People video on systems with NTSC cameras in H.264 high-
profile calls.
