flexibility to meet a wide variety of functional and performance application requirements. The dual power supply
provides protection against power system failures. The Cisco IP/VC 3540 Series is easy to install and maintain.
The Cisco IP/VC 3540 Series mix-and-match options include:
• The Cisco IP/VC 3540 Series Multipoint Conference Unit (MCU) module supports multiparticipant
videoconferences, with a capacity of up to 100 conference participants per module.
• The Cisco IP/VC 3540 Series Rate Matching Module offers the flexibility to support multiple video rates in a
single conference.
• The Cisco IP/VC 3540 Series H.320-to-H.323 Gateway module connects ISDN-based H.320 videoconference
systems to H.323 users, or brings legacy H.320 systems into a H.323 multipoint conference.
• The Cisco IP/VC 3540 Series Application Server module and T.120 Data Conferencing Application together host
document sharing, interactive whiteboard, and other collaboration tools critical to multimedia conferences, with
a capacity of up to 100 conference participants per module.
The Cisco IP/VC 3540 Series Multipoint Conference Unit
The Cisco IP/VC 3540 Series MCU module is a powerful, advanced solution for real-time voice- and video-over-IP
conferencing services. Designed for the Cisco IP/VC 3540 Series Videoconferencing System, the module provides
cost-effective, high-quality, high-performance MCU technology. Its rich feature set makes it a superior solution for
IP-centric videoconferencing over large enterprise communications networks.
The MCU supports:
• High-video-quality multipoint conferences, impromptu or scheduled
• Online conference monitoring and control
• 128- and 384-kbps business-quality videoconferences
• 768-kbps high-quality to 2-Mbps super-quality video sessions
• Two video display modes:
–
Voice Switched: All participants see a single location—the location of the current speaker. When the speaker
changes, the MCU automatically switches the video to the new speaker’s location.
–
Continuous Presence: All participants see a four-way view with one conference location in each quadrant. In
conferences with more than four participants, audio detection logic automatically brings an off-screen speaker
into a quadrant in the four-way display
• QCIF to CIF continuous presence for low delay and efficient network bandwidth utilization
• Audio announcements when participants join or leave a conference
• Web-based conference management, including:
–
Participant management—adding or dropping conference participants or locations
–
Chair control—fixing the video source to a selected participant or location
–
Audio source control—mute the audio from a participant or location
–
Video image management—fix any video source in a continuous presence conference to a selected quadrant
of the four-way display
• Dynamic, midconference bandwidth adjustment
• T.120 data collaboration integrated with any multipoint conference
