Appendix - Polycom Open Collaboration Network (POCN)
Polycom, Inc. 390
Supported on HDX, Polycom ITP and Cisco CTS systems.
● The following content compatibility options are available:
None (TIP not enabled) – TIP endpoints cannot join the conference.
Prefer TIP - Both TIP and non-TIP endpoints can share content via H.264, base profile, using
resolution and rate as described above.
For more information see Procedure 4: Configure a TIP Enabled Profile on the Collaboration
Server.
Procedure 1: Set the MIN_TIP_COMPATIBILITY_LINE_RATE
System Flag
The MIN_TIP_COMPATIBILITY_LINE_RATE System Flag determines the minimum line rate at which an
Entry Queue or Meeting Room can be TIP enabled.
In Collaboration Servers 2000/4000/1800, CTS version 1.9.1 is required, and if CUCM is present in the
environment, a minimum line rate of 1280 kbps must be set in the conference profile. Calls at lower line rates
are rejected, therefore the System Flag value must be set to 1280 or higher.
In Collaboration Server Virtual Edition, CTS version 7 is required, and if CUCM is present in the
environment, a minimum line rate of 1024 kbps must be set in the conference profile. Calls at lower line rates
are rejected, therefore the System Flag value must be set to 1024 or higher.
HD Video Resolutions for TIP calls are determined according to the following table:
For more information see Modifying System Flags.
