Main Features and Benefits
The Cisco Unified Videoconferencing 3545 System offers important features and benefits for video users-and for your organization.
Multiprotocol Support: Broad Video Interoperability
The Cisco Unified Videoconferencing System supports multiple video and audio compression standards, codecs, and protocols, including H.323, Session Initiation Protocol (SIP), Skinny Client Control Protocol (SCCP), and H.320, to help ensure broad connectivity with traditional and emerging video environments. This degree of support provides flexibility that allows Cisco Unified Videoconferencing solutions to interoperate with traditional room and desktop video conferencing systems, Cisco WebEx
™ Meeting Center, Cisco TelePresence solutions, Cisco video telephony environments, and unified communications clients, including Cisco Unified Personal Communicator, Microsoft Office Communicator, and IBM Lotus Sametime. Providing a single video infrastructure solution for a broad range of devices and access methods helps simplify the user experience and system management, facilitating effective video communications and enabling a lower total cost of ownership (TCO).
High-Performance, Flexible Solution: Optimized Experience for All
The Cisco Unified Videoconferencing 3545 System uses a powerful hardware design with flexible processing capabilities to provide an exceptional user experience that is also scalable and cost effective. The products are specifically designed to meet the needs of today's heterogeneous video environments by maintaining HD quality for HD endpoints while simultaneously providing highly scalable SD and desktop video conferencing.
• HD conferencing: Connections to HD-capable endpoints deliver full-screen voice-activated switching in HD, full interoperability with SD endpoints in the same conference, and continuous presence. The HD services run simultaneously on the MCU with both the high-quality and high-capacity SD video services. For the best HD experience and capacity, the next generation Cisco Unified Videoconferencing 5230 MCU is recommended.
• High-quality SD video conferencing: Every port has dedicated encoders, and the system automatically implements transcoding and connection-speed transrating so endpoints can connect to any conference, at any supported bit rate, with any supported audio or video codec, at any supported resolution, and with any screen layout. This approach helps ensure an optimal experience for each participant. 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.
• High-capacity SD video conferencing: The Cisco Unified Videoconferencing 3545 System has the flexibility to redistribute processing resources. If available bandwidth is not fully used, the number of available ports automatically increases, making the solution highly cost effective for desktop video and video telephony deployments.
Extensive Features for Meeting Control and Flexible Video Presentation
The Cisco Unified Videoconferencing 3545 System offers two modes of video display: voice-activated video selection and continuous presence. The H.239 standard is also fully supported, allowing conference participants to share content in real time. The solution provides extensive conference-management functions. 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 as well as add, mute, or disconnect participants. Having access to these integrated controls improves meeting effectiveness, particularly in large video conferences or educational environments.
Integrated Unified Communications and Rich-Media Conferencing Solution
The Cisco Unified Videoconferencing 3545 System is integrated with the Cisco Unified Communications solution to enable multiple video environments and use scenarios, including impromptu conferences that you can initiate from desktop communications clients and phones; collaborative conferences that integrate voice, video, and web conferencing; and traditional multilocation video conferencing. You 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. Unified communications interoperability also delivers investment protection by helping ensure that your organization can fully use your investment in video conferencing systems. The Cisco Unified Videoconferencing 3545 System supports the following deployment modes, which can be used separately or together:
• Traditional IP videoconferencing: The solution provides flexible, scalable, and high-performance multiparty video conferencing for traditional room-based video conferencing systems across a wide variety of endpoints, including H.320, H.323, SCCP, and SIP devices.
• Cisco TelePresence interoperability: When used in conjunction with the Cisco TelePresence Multipoint Switch, the Cisco Unified Videoconferencing 3545 System provides an SD bridge between traditional video conferencing endpoints and Cisco TelePresence endpoints, allowing your business to protect and take full advantage of your investments.
• Cisco WebEx Meeting Center interoperability: When used with the Cisco Unified Videoconferencing Manager, the Cisco Unified Videoconferencing 3545 System provides more advanced video capabilities for Cisco WebEx Meeting Center. The solution lets you display standards-based video clients, room systems, and Cisco TelePresence endpoints in Cisco WebEx Meeting Center meetings. The Cisco Unified Videoconferencing with WebEx® solution also increases the number of video participants that can be viewed, improves the resolution of displayed video, and adds video controls.
• Rich-media conferencing: The Cisco Unified Videoconferencing 3545 System, when combined with the Cisco Unified MeetingPlace® Video Integration option, delivers video conferencing capabilities for Cisco Unified MeetingPlace 6.0 conferencing and earlier. The solution integrates enterprise-class voice, video, and web conferencing with industry-leading video setup and control capabilities.
Note: Cisco Unified MeetingPlace 7.0 and later unify voice and video conferencing in a single media server appliance that does not require Cisco Unified Videoconferencing. Cisco Unified Videoconferencing complements Cisco Unified MeetingPlace 7.0 by providing HD conferencing and interoperability with Cisco TelePresence and WebEx solutions.
• Cisco video telephony: Cisco Unified Communications Manager video telephony dramatically simplifies your video experience by making video communications as easy as placing a telephone call (Figure 1). The Cisco Unified Videoconferencing 3545 System provides multiparty conferencing support for video telephony environments. The solution makes initiating or adding a user to a conference as easy as pressing the conference control on a Cisco Unified IP Phone or video telephony application, such as Cisco Unified Personal Communicator.
Figure 1. Cisco Video Telephony: Video Calls Are as Easy to Place as Telephone Calls
• When deployed with the Cisco Unified Videoconferencing Manager, Cisco Unified Videoconferencing enhances the collaboration capabilities of Microsoft Office Communicator and IBM Lotus Sametime by adding support for standards-based, multiparticipant video. Microsoft Office Communicator and Lotus Sametime users can initiate impromptu video communications with other Microsoft Office Communicator and Lotus Sametime users and with any video solution that can connect to Cisco Unified Videoconferencing, including the Cisco TelePresence System.
Modular, Scalable Solution That Uses an Intelligent Network
Each Cisco Unified Videoconferencing 3545 System consists of a modular chassis that supports MCU, EMP, and ISDN gateway modules for a wide variety of video conferencing features and capacities. The Cisco Unified Videoconferencing ISDN Gateway modules allow ISDN H.320 endpoints to participate in the same conferences as IP-based H.323, SCCP, and SIP endpoints, providing investment protection for ISDN video conferencing deployments. The Cisco Unified Videoconferencing 3545 System also works with the Cisco Unified Videoconferencing 3515 MCU and the Cisco Unified Videoconferencing 3522 Basic Rate Interface (BRI) and 3527 Primary Rate Interface (PRI) Gateway appliances, which you can readily deploy at remote network sites to provide a distributed video environment, optimizing WAN bandwidth use for geographically dispersed organizations.
Video conferencing deployments with the Cisco Unified Videoconferencing 3545 System often require the presence of an H.323 gatekeeper in the video network to provide functions such as telephone number-to-IP address resolution and zone bandwidth management for video conferencing endpoints. Based on Cisco IOS
® Software, the Cisco IOS Gatekeeper runs on a wide variety of Cisco integrated services routers. The Cisco Unified Border Element, also a Cisco IOS Software product, can enhance a video conferencing deployment by providing session-border-control services, quality-of-service (QoS) functions, and enhanced security with firewall traversal capabilities, all of which allow you to extend your video conferencing capabilities beyond your network to partner and customer networks, or even to video endpoints using the public Internet.
The Cisco Unified Videoconferencing System can be managed as standalone devices or with the Cisco Unified Videoconferencing Manager, which helps organizations of all sizes use their video conferencing resources more effectively and extend desktop video access to new classes of users. The Cisco Unified Videoconferencing Manager allows you to easily schedule video conferences from a web browser or a Microsoft Outlook or IBM Lotus Notes calendar, where you can view, check availability, and reserve video resources, such as Cisco Unified Videoconferencing MCU devices and gateways. Additional features such as custom meeting templates that identify bandwidth, layout, and terminal setting preferences; Lightweight Directory Access Protocol (LDAP) integration; email notifications; and automatic dial-out to video terminals help make the scheduling and attending experience flexible and efficient, thereby reducing TCO and the need for support. You can also record and play back video conferences.
Cisco Unified Videoconferencing Manager reduces the hurdles to deployment of 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 in-meeting controls.
Cisco Unified Videoconferencing Manager also includes desktop video capabilities, including fully interactive video, one-way video streaming, and interoperability with Microsoft Office Communicator, IBM Lotus Sametime, and Cisco WebEx Meeting Center. Anyone with a PC, web browser, and webcam can join a video conference as a fully interactive video participant whether the person is inside or outside the corporate firewall. The streaming video features allow anyone with a web browser to view a live video stream of a conference, which is well suited for meetings such as panel discussions with a large audience but in which only a subset of the attendees actively participates. Eliminating the need to be connected to the enterprise network or have access to traditional video endpoints makes it easier for traveling or remote employees, partners, and customers to participate and gain the benefits of visual communications. Microsoft Office Communicator and Lotus Sametime interoperability provides interoperability with standards-based video solutions and lets you initiate multiparticipant video directly from a buddy list or an instant message.
