Port Capacities of the 3545 MCU
The Cisco Unified Videoconferencing 3545 MCU can be configured to support a wide range of audio
and/or video ports.
The Cisco Unified Videoconferencing 3545 MCU supports switched High Definition video service
types. HD services enable Voice Activated single-screen displays at up to 2 Mbps, and offer resolutions
of 1280 x 720 pixels (720p) and 1920 x 1080 pixels (1080p).
HD service types also enable you to set a minimum downspeeding bandwidth rate which is common to
all endpoints participating in a conference.
Cisco Unified Videoconferencing 3545 MCU conferencing includes two types of cards:
• Cisco Unified Videoconferencing 3545 MCU—An MCU card that is responsible for the signaling
and the audio. When working alone, this card can only do audio conferencing of 96 audio ports. It
can be mixed and matched with up to four EMP cards to create a 96 flat port video bridge. The
Cisco Unified Videoconferencing 3545 MCU card has no video capabilities.
• Cisco Unified Videoconferencing 3545 EMP Enhanced Media Processor (EMP)—A video
processing card that can support 36 standard rate video ports (up to 384 Kbps) or 24 high rate video
ports (up to 2 Mbps).
Table 1-2 shows the port capacity for different Cisco Unified Videoconferencing 3545 MCU
configurations.
