Key Features and Benefits
The Cisco Unified Videoconferencing 3515 MCU offers important features and benefits for
videoconference users—and for your organization.
Multiprotocol Support that Enables Broad Video Interoperability
Cisco Unified Videoconferencing systems support multiple video and audio compression
standards, codecs, and protocols, including H.323, Session Initiation Protocol (SIP), Skinny Call
Control Protocol (SCCP), and H.320, to ensure broad connectivity with traditional and emerging
video environments. This degree of support provides flexibility that enables Cisco Unified
Videoconferencing solutions to interoperate with traditional room and desktop video conferencing
systems, newer high-definition video solutions, and Cisco Unified Communications Manager video
telephony environments. Providing a single video infrastructure solution for a broad range of
endpoints and access methods improves usability for users and simplifies management, enabling
effective video communications and a lower total cost of ownership.
High-performance, Flexible Solution that Delivers an Optimized Experience for All Users
The Cisco Unified Videoconferencing 3515 MCU is designed using an encoder-per-port hardware
architecture, which provides dedicated resources for every endpoint connected to a conference.
This architecture allows the product to support a wide range of video and audio compression
standards, codecs, continuous-presence features, and video resolutions at high performance
levels and in any combination, without adversely affecting the capacity of the product.
High-quality standard definition (SD) video conferencing—Because every port has
dedicated audio and video encoders, any SD endpoint can connect to any conference, at
any supported bit rate, with any supported audio or video codec, at any supported SD
resolution, and with any screen layout. The Cisco Unified Videoconferencing 3515 MCU
automatically implements audio and video transcoding and connection speed transrating
capabilities that allow each SD endpoint to use its preferred codec and connection speed
and still connect to conferences with endpoints using different codecs and connection
speeds. This approach helps ensure an optimal video and audio experience for each
participant without sacrificing scalability or performance. The encoder-per-port hardware
architecture also significantly reduces planning, provisioning, and scheduling requirements
by eliminating the need to define or limit the bit rates, video formats, and conference
features that video conferencing endpoints and conference participants can use.
High-capacity personal video conferencing—The Cisco Unified Videoconferencing 3515
MCU now has unmatched flexibility to distribute processing resources that are not being
fully used by personal or desktop video conferencing endpoints that do not require high
connection rates. If the available bandwidth is not fully used, the number of available ports
automatically increases, providing a reduced cost per port. This new MCU service can run
concurrently with the high-quality SD service and adds powerful flexibility that makes the
Cisco Unified Videoconferencing 3515 MCU an even more cost-effective choice for desktop
video and videotelephony deployments.

Data Sheet
High definition (HD) conferencing—The Cisco Unified Videoconferencing 3515 MCU 5.1
also introduces support for standards-based HD video conferencing endpoints. HD
endpoints are shown in full screen, and switching between participants is determined by the
active speaker. The HD switched service has the same port capacity as the transcoded SD
services and can run simultaneously on the MCU with SD and high-capacity personal video
services, automatically providing the optimal experience and capacity for the entire
spectrum of video users and deployments.
Extensive Features that Provide Meeting Control and Flexible Video Presentation
The solution offers two modes of video display: voice-activated video selection and continuous
presence. In a voice-activated conference, participants see a full screen of the person who is
actively speaking. As the speaker changes from one location to the next, the video follows to show
the new speaker. In a continuous-presence conference, the display shows the video of 2 to 16
participants simultaneously, with any additional meeting participants being cycled from off to on
screen as they speak. In either mode, a conference moderator can manually control every aspect
of the conference display through an easy-to-use Web-based interface, including determining how
many participants should be shown on screen at once, which windows should be voice-activated
vs. continuous presence, and many other options.
Conference management functions—The Cisco Unified Videoconferencing 3515 MCU provides
extensive conference management functions so users can control all aspects of their meeting.
Users and conference moderators can control the meeting from a Web-based user interface, a
dual tone multifrequency (DTMF) interface from video endpoints or standard phones, or video
endpoint remote controls. For example, the conference moderator can lock the conference to
prevent additional or uninvited participants from attending, as well as add, mute, or disconnect
participants. In multiple-image continuous-presence conferences, the administrator can specify the
screen position in which the locations appear and switch between multiple- and single-image
displays at the click of a mouse. Having access to these integrated controls improves meeting
effectiveness, particularly in large videoconferences or educational environments.
Integrated Unified Communications and Rich-Media Conferencing Solution
The Cisco Unified Videoconferencing 3515 MCU is integrated with the Cisco Unified
Communications System to enable multiple video environments and usage scenarios, including
impromptu conferences that can be initiated from desktop communications clients and phones;
collaborative conferences that integrate voice, video, and Web conferencing; and traditional
multilocation video conferencing. Users can easily transition across and between applications,
such as presence, instant messaging (IM), IP telephony, unified messaging, and rich-media
conferencing as interactions warrant, independent of where they are or what device they are using.
These broad integration capabilities enable Cisco Unified Videoconferencing solutions to deliver
advanced productivity and simplify the implementation and deployment of unified communications
and rich-media conferencing solutions. Unified communications interoperability also delivers
investment protection by ensuring that organizations can fully use their investment in video
conferencing systems. The Cisco Unified Videoconferencing 3515 MCU enables three types of
solutions, which can be deployed and used separately or together.
®
Rich-media conferencing—The Cisco Unified MeetingPlace solution—also part of the
Cisco Unified Communications System—is a complete rich-media conferencing solution
(Figure 1). The Cisco Unified Videoconferencing 3515 MCU, when combined with the Cisco
Unified MeetingPlace Video Integration option, delivers the video conferencing capabilities

Cisco Video Telephony—Cisco Unified Communication Manager video telephony extends
video to desktop communications. Video calls are now as easy to place as telephone calls
(Figure 2) and have familiar phone features such as hold, transfer, and call forward;
integrated dial plans; common call detail records (CDRs); and administration capability.
Cisco Video Telephony personalizes communications and extends the benefits of video
communications from the conference room to the end user’s desktop and dramatically
simplifies the user experience. The Cisco Unified Videoconferencing 3515 MCU provides
multiparty conferencing support for video telephony endpoints, including both traditional
room-based systems and desktop applications and devices. The solution provides a simple
user experience that makes adding users to a conference as easy as pressing the
conference control on a supported video telephony application or device, such as a Cisco
Unified IP phone or Cisco Unified Personal Communicator.

conferencing environments, the Cisco Unified Videoconferencing 3515 MCU provides
flexible, scalable, and high-performance multiparty video conferencing for traditional roombased video conferencing systems across a wide variety of endpoints, including H.320,
H.323, SCCP, and SIP devices.
Scalable Solution Deployed Over an Intelligent Network
Each Cisco Unified Videoconferencing 3515 MCU is a self-contained, preconfigured highperformance appliance that provides audio and video processing for small to medium-sized
conferences. The solution can be deployed with the Cisco Unified Videoconferencing 3522 and
3527 Gateway appliances, which allow ISDN H.320 endpoints to participate in the same
conferences as IP-based H.323, SCCP, or SIP endpoints, providing investment protection for
existing video conferencing deployments. Readily deployable at remote network sites, the Cisco
Unified Videoconferencing 3515 MCUs also work with the Cisco Unified Videoconferencing 3545
systems at larger sites to provide a distributed video environment that optimizes WAN bandwidth
usage for geographically dispersed organizations while preserving solution performance and
quality of the user experience.
Video conferencing deployments with the Cisco Unified Videoconferencing 3515 MCU requires the
presence of an H.323 gatekeeper in the video network to provide functions such as telephonenumber-to-IP address resolution and zone bandwidth management for video conferencing
®
endpoints. Based on Cisco IOS Software, the Cisco IOS Gatekeeper product runs on a wide
variety of Cisco integrated services routers. The Cisco IP-to-IP Gateway, also a Cisco IOS
Software product, can enhance a video conferencing deployment by providing session-bordercontrol services, quality-of-service (QoS) functions, and enhanced security with firewall traversal
capabilities, all of which allow customers to extend their video conferencing capabilities beyond
their network to partner and customer networks, or even to video endpoints using the public
Internet.
Advanced Solution Management—Cisco Unified Videoconferencing Manager
Cisco Unified Videoconferencing systems can be managed as a standalone device or with the
Cisco Unified Videoconferencing Manager, which helps organizations of all sizes improve
communications by using their video conferencing resources more effectively. The Cisco Unified
Videoconferencing Manager enables any user to easily schedule video conferences from a Web

browser or a Microsoft Outlook calendar where they can view, check availability, and reserve video
resources, such as Cisco Unified Videoconferencing MCUs, and gateways. The application
minimizes complexity and ensures optimal resource usage by automatically communicating with
multiple MCU and gateway devices across multiple geographical locations to reserve the
appropriate resources at the most efficient locations. Additional features such as custom meeting
templates that identify bandwidth, layout, and terminal setting preferences; Lightweight Directory
Access Protocol (LDAP) integration; e-mail notifications; and automatic dialout to video terminals
help make the scheduling and attending experience flexible and efficient, thereby reducing the
need for help desk support and the total cost of ownership.
Cisco Unified Videoconferencing Manager reduces the hurdles to deploying video conferencing to
large or geographically dispersed environments. Video conferencing devices are registered with
Cisco Unified Videoconferencing Manager, which then combines the device information, network
topology, and bandwidth information to help simplify user and administrator interactions and make
intelligent resource allocation decisions. Cisco Unified Videoconferencing Manager also helps
improve meeting effectiveness by providing powerful in-meeting controls, such as the ability to
invite new users, mute and unmute participants, and change the meeting video layout for any
video conference on the network from a single, centralized Web user interface.
