Port Capacities
The Cisco Unified Videoconferencing 3515 MCU supports switched High Definition (HD) video service types. The switched HD service enables Voice Activated
Cisco Unified Videoconferencing 3515 MCU12 Port Capacity
Cisco Unified Videoconferencing 3515 MCU12 supports a fixed number of ports:
•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.
–Mixed QCIF/CIF/4CIF/720p conferences (4CIF is provided with H.263 at 15fps).
–Unlimited number of conferences of which one can be a high definition conference at any given time.
Note When using a High Definition Switched Video service type, only a single screen layout is available.
High definition participants must have H.264 only and receive 720p in order to view the conference in high definition, otherwise the endpoint is considered as a standard definition endpoint.
