Resumen del manual
Today’s world consists of many different networks and video protocols. Supporting IP networks alone may not be sufficient to address this.The MGC-50 can be easily upgraded to provide multi-network gateway connectivity. Simply adding additional network modules turns your entry-level MGC-50 into a complete video network switch/gateway for IP, ISDN and ATM networks. BROADBAND VISUAL COMMUNICATIONS ARCHITECTURE The MGC-50 provides enterprise class reliability and availability in a stand-alone or rack mountable chassis. • From 6 to 192* ports IP • Connection speeds up to 1.5Mbps (IP) • Mission critical fault-tolerant design • 8 slot chassis • All modules: - Front accessible - Hot-swappable -Self-configuring -Compatible with MGC-100™ MULTI-NETWORK CONNECTIVITY The MGC-50 provides IP, ISDN and ATM in a single platform. • Connects directly with H.323 (IP) networks • Supports H.320 (ISDN) and H.321 (ATM) networks • Designed to incorporate new standards as they emerge, all within a single platform • All supported networks can access and utilize the MGC-50’s advanced features The MGC-50 provides the most advanced features of any MCU. Now you can produce your conference, any way you want, making the remote meeting experience more like a face-to-face meeting. Continuous Presence • Up to 21 different layouts • Layouts changeable ‘on-the-fly’ • Each window within each layout can be set as fixed or voice activated Multi-Way Transcoding • Allows sites with different frame rates, connection speeds, audio algorithms, resolutions, and network protocols to transparently connect with one another • Ensures that all sites connect at their optimal capabilities • Ensures that conferences start on time by simplifying the connection process • Ensures conference reliability Greet and GuideTM (ISDN and ATM) • Customizable conference welcome screens and audio greeting messages • Operator(s) can guide users through every part of the conference: - Greet users as they connect - Drag and drop participants between conferences - Create subconferences Powerful Management System The MGC-50 provides the most flexible suite of system and conference management applications of any MCU. Three different management applications are offered to provide the power and flexibility required for both local and remote access and support. • WebCommander™ empowers users to schedule and manage their own conferences using Netscape or Microsoft Web browsers • MGC Manager™ provides comprehensive operator control - from conference scheduling and management to system configuration, diagnostics and maintenance • Touch Tone Conference Manager (TTCM) empowers users to manage their own conferences using a standard touch-tone telephone Easy Maintenance The MGC-50 reduces the need for on-site maintenance through advanced remote system monitoring tools. • Remote diagnostics and problem resolution • Remote software downloads • Support for multiple MGC systems Advanced Features That Make A Difference! • NO external gateways necessary Rich Media Communications is a real-time virtual communications experience…anytime, anywhere. The Accord Product Line provides the tools that make virtual communications a reality, enhancing the way people communicate and interact.With the Accord Product Line the user is ensured of a networking solution which makes rich media applications such as business conferencing, telemedicine, distance learning, visual enabled e-commerce, visual call centers and visual chat rooms a reality.
