Polycom, Inc. 2-9
—Video forcing works in the same way as in Lecture Mode when Presentation Mode
is activated, that is, forcing is only enabled at the conference level, and it only
applies to the video layout viewed by the lecturer.
•Telepresence Mode (CP Conferences only) - enables the connection of numerous high
definition telepresence rooms and of different models (such as TPX and RPX) into one
conference maintaining the telepresence experience. This mode is enabled by a special
license.
•Encryption – Used to enhance media security at conference and participant levels. For
more information, see "Audio Algorithm Support” on page 4-35.
•Conference Recording - The RMX enables audio and video recording of conferences
using Polycom RSS 2000 recording system.
•Packet Loss Concealment (PLC) - for Siren audio algorithms improves received audio
when packet loss occurs in the network. PLC is enabled by the SET_AUDIO_PLC
System Flag in system.cfg
—PLC for Audio is supported with MPM+ and MPMx cards only.
—The speaker’s endpoint must use a Siren algorithm for audio compression.
—The following audio algorithms are supported:
•Siren 7 (mono)
•Siren 14 (mono/stereo)
•Siren 22 (mono/stereo)
•Auto Brightness - detects and automatically adjusts the brightness of video windows
that are dimmer than other video windows in the conference layout.
—Auto Brightness is supported with MPM+ and MPMx cards only.
—Auto Brightness only increases brightness and does not darken video windows.
•Audio Clarity - improves received audio from participants connected via low audio
bandwidth connections, by stretching the fidelity of the narrowband telephone
connection to improve call clarity.
—Audio Clarity is supported with MPM+ and MPMx cards only.
—Audio Clarity is applied to the following low bandwidth (4kHz) audio algorithms:
• G.729a
• G.711

TIP Support

TIP is a proprietary protocol created by Cisco for deployment in Cisco TelePresence systems
(CTS). Polycom’s solution is to allow the RMX to natively inter-operate with Cisco
TelePresence Systems, ensuring optimum quality multi-screen, multipoint calls. For more
information, see "Collaboration With Cisco’s Telepresence Interoperability Protocol (TIP)” on
page I-1.

Operator Conferences (CP only Conferences)

Offers additional conference management capabilities to the RMX users, enabling them to
attend to participants with special requirements and acquire participant details for billing
and statistics. This service is designed usually for large conferences that require the personal
touch. Operator assistance is available in MPM, MPM+ and MPMx Card Configuration
Modes. For more information, see Chapter 10, “Operator Assistance & Participant Move” on
page 10-1
