The MGC unit can connect the endpoints via ISDN, T1-CAS, IP, ATM and serial connections (MPI), allowing participants from any deployed network to participate in a conference, without the need for external gateways and other equipment. Figure 2-1 shows a basic multipoint conferencing scheme and connection types. Figure 2-1: Multipoint Video Conferencing using MGC 2-1 Chapter 2 - MGC Manager Overview MCU Management The MGC unit is controlled by the MGC Manager application installed on a customer-provided computer or server. The application works with the following operating systems: Windows 98 R / ME R / NT R / 2000 R / XP R . The operator's workstation connects to the MGC unit using: · · · · Ethernet LAN (other than the LAN used for conferencing) TCP/IP Internet RS-232 Dial-up modem Up to 30 local or remote MGC Manager workstations can connect to a single MGC unit simultaneously. A single operator can control multiple MGC units and conferences. The MGC unit can also be controlled through a Web browser via the MGC WebCommander application. Using the MGC Personal Scheduler add-on, conferences can be scheduled from the MCU in Microsoft's Outlook. Figure 2-2 illustrates the MGC Manager system components. Figure 2-2: MGC Manager - MCU Connection 2-2 MGC Manager User's Guide - Volume I MGC System Main Features This section briefly describes the main features of the MGC system. Universal Transcoding For each endpoint connected to a conference, the MGC's Universal Transcoding gateway automatically resolves: audio compression, video protocol, video resolution, frame rate, bandwidth, and T.120 transfer rate. The gateway then performs any necessary translations "on the fly". This capability makes the connection fast and seamless for multipoint calls, and ensures that each endpoint operates at their optimal capability. Figure 2-3 shows an example of a transcoding scheme. Figure 2-3: Transcoding performed by the MGC unit 2-3 Chapter 2 - MGC Manager Overview Dynamic Continuous Presence The dynamic Continuous Presence capability of the MGC system enables user friendly viewing flexibility and conference interaction. This type of video session offers multiple viewing options and window layouts for video conferencing. Continuous Presence for video conferencing is available in three modes: · · · Classic Quad Views Software The Continuous Presence Classic mode offers 21 layouts to accommodate different numbers of participants and conference settings. Figure 2-4 shows these layouts. Figure 2-4: Continuous Presence Classic Mode - Video Layouts 2-4 MGC Manager User's Guide - Volume I The Continuous Presence Quad Views mode offers three additional window layouts for larger conferences with more than 10 participants, for example: 4x4, 2+8, 1+12. Figure 2-5 shows these layouts. Figure 2-5: Continuous Presence Quad Views - Additional Video Layouts For conferences with more participants than display windows, the MGC's dynamic video mix capability allows the site mix (which sites can be seen) to be modified throughout the conference. The video layout can be defined during conference definition (reservation stage) or changed during an On Going Conference, allowing participants to view different screen layouts of other conference participants. These layout options provide greater flexibility when displaying a large number of participants and help maximize the effectiveness of the video conference. When Continuous Presence Classic or Quad Views conferences are set to Auto Layout, the MGC system automatically selects the conference layout based on the number of currently connected participants in the conference. In addition, when video participants are connected or disconnected, the conference video layout automatically adjusts to reflect the changed number of participants. The selected video layout is not affected by the Audio Only participants, when they connect or disconnect to or from the conference. The Continuous Presence - Software (Software CP) is a software solution for IP only conferences that resembles Continuous Presence but saves video card resources. In Software CP, only two types of video layouts are available: 2x1 and 2x2, and the Lecture Mode options are disabled. For system requirements and a detailed description of this feature, refer to the MGC Manager User's Guide Volume II, Chapter 1, "Advanced Conference Settings". 2-5 Chapter 2 - MGC Manager Overview Multiple Switching Modes Switching between video participants can be performed using these features: · · · · Voice activation Operator-force via the MGC Manager to and/or the MGC WebCommander Selecting certain participant display windows as fixed and others as voice-activated Lecture Mode and Lecture Show - The lecturer is viewed in full screen by all conference participants, while the audience is "scanned" for the speaker's view. Presentation Mode - available in Continuous Presence conferences. When the speaker's presentation extends beyond a predefined time, that speaker becomes the lecturer and the conference switches to Lecture Mode. · You can select multiple switching options at the reservation stage or during the On Going Conference. IVR-Enabled Conferencing The Interactive Voice Response (IVR) is a software module that automates the connection process and lets participants and chairpersons perform various operations during the On Going Conference. By combining the input of the caller with the menu-driven scripts (DTMF codes), participants can call the conference dial-in number and use a touch-tone telephone or the endpoint's remote control to interact with the conferencing system. The Entry Queue Service is a subset of the IVR Service, and it can be used in conjunction with IVR for routing dial-in participants. An Entry Queue Service must be used in Ad Hoc (reservation-less) conferencing. This allows callers to initiate an On Going Conference without prior scheduling, based on conference parameters taken from a Profile that was assigned to the Entry Queue. This service also enables the system to verify the participant's right to start an Ad Hoc conference or to join an On Going Conference. Using a set of voice prompts, the system routes the callers from the Entry Queue to the appropriate conference. 2-6 MGC Manager User's Guide - Volume I The IVR service enables the following operations that let operators facilitate and manage conferencing: · · · · · Personally guide individual participants to the conference Monitor all participants who are currently waiting in the Entry Queue and IVR Queue regardless of their conference association Assist participants in the Entry Queue, IVR queue, or during the conference Conduct Voting sessions Control Question and Answer sessions Using IVR and DTMF codes, participants and chairpersons can perform various management operations during a conference, for example: · · · · · · · · · · · · · · · · · Request personal assistance Request assistance for conference (Chairperson) Lock or unlock conferences to dial- in participants (Chairperson) Adjust the participant's broadcasting and listening audio volume (All) Mute or unmute the participant's audio channel (All) Mute all participants except the requesting participant (Chairperson) Cancel the Exclusive Speaker mode (Chairperson) Mute "Meet Me" dial-in participants upon their connection to the conference (Chairperson) Change the conference password (Chairperson) Place the conference on-hold (Chairperson) Reinstate an on-hold conference (Chairperson) Manage a Question-and-Answer session (Chairperson) Conduct a Voting session (Chairperson) Play the Help menu Enable or disable the Roll Call feature (Chairperson) Request a Roll Call and stop the Roll Call names review (Chairperson) End (manually terminate) the Conference (Chairperson) The IVR software module requires the installation of the Audio+ card in the MCU. For a detailed description of the IVR module, refer to the MGC Manager User's Guide Volume II, Chapter 2. 2-7 Chapter 2 - MGC Manager Overview Entry Queue An Entry Queue is a special routing lobby to which one or several dial-in numbers are assigned. When callers dial this number, they access this Entry Queue where they wait to be routed and connected to the conference. The following Entry Queue options are available: Unattended Entry Queue Both video and audio participants (including IP phones) connect to the Entry Queue and, using voice prompts, are routed to their conference according to the conference numeric ID or password (depending on the MCU configuration) they submit. This process is automatic, unless the participant requires help. Depending on the Entry Queue service configuration, operator assistance may be available to all participants during the connection process. Attended Entry Queue Dial-in participants are personally greeted by an operator (in an Operator conference) who accompanies them to their conference. Ad Hoc-enabled Entry Queue An On Going Conference is initiated from an Entry Queue that is configured to support Ad Hoc (reservation-less) conferencing. The conference is created according to the Profile assigned to the Ad Hoc-enabled Entry Queue. For a detailed description of this feature, refer to the MGC Manager User's Guide Volume II, Chapter 3, "Ad-Hoc Conferencing and External Database Authentication". 2-8 MGC Manager User's Guide - Volume I Video+ Features The Video+ board supports the following features and enhancements: · · · Ability to run conferences across Video+ cards without fragmentation H.264, H.263 and H.261 video protocol for high quality transmission Conference On Port (COP) mode - Continuous Presence video layouts may be viewed by all participants while using only one video port, increasing the number of participants in a video conference Click&View application - an endpoint application that lets participants select their personal video layout from their endpoints via DTMF codes Continuous Presence video layouts for large conferences (10 or more participants) Improved image quality in Continuous Presence conferences Improved latency in large Continuous Presence conferences Choice of a personal video layout for participant Visual effects for video display (background color, window border color and speaker indication color) Enhanced video quality through the use of 4CIF video resolution Full size window for speaker view in asymmetrical Continuous Presence layouts · · · · · · · · Encryption Encryption is available at the MCU conference and participant level, based on AES 128 Media Encryption and DH 1024 Key Exchange standards. Encryption is supported in all types of audio and video conferences with ISDN and IP participants. ISDN and IP encrypted participants require more resources than non-encrypted participants. Whether the participant's connection to a conference is encrypted or non-encrypted depends on the encryption setting of the conference or the Entry Queue as well as on the participant's own encryption setting. 2-9 Chapter 2 - MGC Manager Overview Conferencing Capabilities and Options Conference Reservations Features MGC Manager provides the following options: · · · · · · Conferences can be reserved and scheduled ahead of time (Reservations) or set up to start immediately (On Going Conferences) Conference resources are defined and reserved during conference setup Recurrent conferences can be scheduled in advance (a reservation can include recurrent conferences) The central reservations database is easily accessed MGC Manager displays all the defined reservations for multiple MCUs Reservation-less features: Ad Hoc conferencing and Meeting Rooms Conference Setup Features The following options are available when setting up conferences: · · · · · · · · · · Dial-in for undefined participants Dial-in with automatic line rate detection for defined participants Meet Me per Conference Meeting Rooms Dial-out (manual or automatic) Automatic line rate detection for undefined dial-out participants On-demand conferencing Entry Queue access (using one dial-in number for all conferences) Interactive Voice Response (IVR) software module for moderated conference access Greet and Guide with manual or automatic guidance to conferences 2-10 MGC Manager User's Guide - Volume I Conference Management and Monitoring Features MGC Manager provides capabilities for management and monitoring of participants and conferences, including the following: · · · · · · · · · · · · · · · · · · · · · · · Lecture Mode, Lecture Show or Presentation Mode in Continuous Presence conferences Far End Camera Control (FECC/LSD) in video conferences H.243 Cascading conferences H.243 Chair Control for video conferences Streaming of video and data according to endpoint type (Dual Stream) Management and monitoring of Voting and Q&A sessions Automatic termination of idle (no participants) conferences Automatic extension of conference duration Control of listening and broadcasting audio volume for individual participants Automatic detection and muting of noisy line participants (SilenceIT) Auto Gain Control (AGC) noise and audio volume regulation for individual participants Advanced control and greetings for attended conferences Conference control via DTMF codes from user's endpoint or telephone Entry, exit and end-of-conference alert tones Media encryption Modification of certain conference properties Option to add new participants during conference Display of all defined reservations for multiple MCUs Easily accessed Call Detail Records (CDR) Cut, copy & paste and/or multiple drag & drop of participants Active display of all system resources Active display of all conferences and participants from multiple MCUs Real-time monitoring of each participant's connection status and properties 2-11 Chapter 2 - MGC Manager Overview MGC Unit Advantages The MGC unit provides the following advantages: Connectivity To provide the flexibility to set up multi-network conferences or to use the MGC unit as a multi-network gateway, the MGC unit can be connected with the following telecommunication lines: · · · · · · · · ISDN T1 lines ISDN E1 lines Leased lines E1/T1 T1-CAS lines ATM (FVC) 25 & 155 Mbit/s IP Networks - LAN (H.323 and SIP) V.35/RS-449/EIA-530 Serial connection (MPI) Scalable Architecture You can increase capacities of the MGC unit by adding ports, software modules or other capabilities as needed, with no performance degradation or capacity bottlenecks.
