Port Capacities
The Cisco Unified Videoconferencing 3515 MCU supports switched High Definition (HD) video
service types. The switched HD service enables Voice Activated single-screen displays at up to 4
Mbps,
and offers resolutions of 1280 x 720 pixels (720p) and 1920 x 1080 pixels (1080p). Switched HD service
types also enable you to set a minimum downspeeding bandwidth rate that is common to all endpoints
participating in a conference.

• 72 ports of fully transcoded audio.
• 24 ports of fully processed desktop video (up to 384 Kbps).
• 12 ports of fully processed high rate video of up to 4CIF and up to 2 Mbps (6 ports when using
encryption above 768 Kbps or when using a bit rate above 2 Mbps).
• 4 ports of high definition continuous presence video.
–
Fully transcoded high rate video.
–
Any Continuous Presence layout.
–
All ports are fully video processed.
–
Any mixture of H.261/H.263/H.264.
