E.
Premium resolution
Explanation:
The Dual display, High definition, and Presentation option keys need not be installed on a Cisco
TelePresence System Codec C60. The following option keys can generally be installed on devices that run
Cisco TelePresence TC software, such as the C series codecs:
Dual display
MultiSite
Presentation
High definition
Premium resolution
The Dual display option key enables dual-display functionality on systems. However, dual-display functionality is
native to the C60 and quad-display functionality is native to the C90. The C20 and C40 all require an option key
to enable full dual-display functionality.
The MultiSite option key enables systems to create ad-hoc conferences without requiring an external multipoint
control unit (MCU). Ad-hoc conferences are on-demand conferences and are limited to four simultaneous
participants. The C60 requires the MultiSite option key in order to support native ad-hoc conferencing.
The Presentation option key, which is sometimes called the Natural Presenter option key, enables systems to
send presentations. This key is supplied by default on new systems. The EX series models include presentation
functionality natively without an option key.
The High definition option key allows 720p definition at 30 frames per second. The C40 and C60 support this
feature natively; the C20 requires the High definition option key to support high-definition functionality.
The Premium resolution option key allows higher resolutions up to 1920 x 1080 at 60 frames per second. All C
series models require an option key to support these higher resolutions.Cisco: Troubleshooting Guide TC 6.0: Option keys (PDF)
