Polycom realpresence group series Administrator's Manual

Call Speeds and Resolutions
Polycom, Inc. 274
The values in the Max Speed for Each Site (ICE Enabled, Lync 2013, Skype for Business 2015) column are
applicable only when both of the following criteria are met:
● The Lync Interoperability option is disabled, so that calls are negotiated with H.263 using Lync 2013
or Skype for Business 2015 clients.
● The ICE calls go across the firewall boundary.
High-Profile Call Speeds and Resolutions
This section includes the H.264 high-profile resolutions and frame rates sent in calls between two
RealPresence Group systems. Resolutions and frame rates are based on both the call speed and the
Optimized for setting of your Camera input.
The values for sharpness and motion are the same from 4 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

Note: Lync interoperability option and CCCP calls
These values do not apply when the Microsoft Lync Interoperability option is enabled, whether it is in a
Lync 2013/Skype for Business 2015 environment. When this option is enabled, all calls are CCCP
calls and are capped at 1920 kbps due to ICE restrictions.
Note: Resolutions and frame rates for disparate endpoints
Due to the complexities of the systems and their capabilities, it is not possible to include tables of the
resolutions and frame rates for calls between a RealPresence Group system and a different type of
endpoint or a multipoint resource. RealPresence Group systems attempt to provide the highest
resolutions and the best frame rates in all types of calls.
