Until all participants connect to conference, the conference shows the Not Full status. If Dial-out Manually was not selected for the conference, the system automatically dials out to all listed participants and connects them to the conference. Defined, dial-in participants status is Waiting for dial-in until they connect to the conference.
Monitoring On Going Conferences
You can monitor On Going Conferences and perform various operations while conferences are running. Three levels of monitoring are available with the MGC Manager:
General Monitoring - You can monitor the general status of all On Going Conferences and their participants in the MGC Manager main window. Conference Level Monitoring - You can view additional information regarding a specific conference and modify its parameters if required, using the Conference Properties option. Participant Level Monitoring - You can view detailed information on the participant's status, using the Participant Properties option. During attended conferences you can monitor the status of the participants waiting in the Participants Queue.
This chapter describes the available options and methods of monitoring Audio Only conferences in the MGC Audio Look and Feel mode, according to monitoring levels and according to the type of participant or the type of connection to the conference. When the Audio Look and Feel mode is set for the system, the video parameters are hidden, but you can still monitor video conferences if they are run on any of the connected MCUs. The Audio Look and Feel mode is set in the Options menu. For more details, refer to the MGC Administrators Guide, Chapter 5, Audio Look and Feel.

Chapter 4 - Operations Performed During On Going Conferences
Management Functions Overview
The MGC Manager operator performs different roles during attended and unattended conferences. Attended Conferences On Going attended conferences require an active Operator conference to run on the same MCU as the attended conference. In attended conferences, participants accessing an Entry Queue or an IVR queue are moved to the Participants Queue where they wait for the operator to assist them. The operators role during this stage is to use the Participants Queue management tools to move the participants from the Participants Queue to the destination conference. During an On Going Conference, the operator can take part in the conference and perform various tasks, for example assist participants privately; conduct a voting session, manage a Question-and Answer session, place participants on hold, and lock the conference to dial-in participants.For a detailed description of Attended Conferencing, see Chapter 7, Attended Conferencing on page 7-1. Unattended Conferences In unattended conferences, participants use DTMF codes in response to menu-driven voice prompts and in this way are guided to the conference. Unless there is a problem in the connection or the participant did not enter the correct conference Numeric ID or password, operator intervention is not required. In unattended conferences the operator usually leaves the management of the conference to a designated participant, usually the chairperson/meeting organizer. The conference chairperson can perform certain operators functions, such as start a voting session, control the Q&A session, mute incoming parties, place the conference on hold and lock or unlock the conference. All chairperson functions can be performed either via the WebCommander interface or using DTMF codes from the participants endpoint.
Participant and Conference Level Operations
Operators can perform functions on conferences that affect individual participants or can affect the conference on the whole. Participant Level Operations The following operator actions are performed at the participant level:
Make dial-out connections Change the participant connection type (dial-in/dial-out) Disconnect and reconnect participants Name undefined dial-in participants Change the properties of a disconnected participant Designate a participant as an Exclusive Speaker Designate a participant as a VIP Control the participant's listening and broadcasting volume Mute or un-mute a participant Modify user defined parameters for the participant (MGC Manager only) Move a participant to an operator conference (attended conference only) Move a participant to the home conference (attended conference only) Place a participant on-hold (attended conference only)

Roll Call can be activated during different conference statuses:
Enabling Roll Call Roll Call must be enabled or disabled at the conference level by assigning a Roll Call enabled IVR Service and by enabling it in the Conference Properties- Settings dialog box. However, if the Roll Call option is not enabled in the IVR Message Service, it cannot be activated for the conference. For more details on enabling Roll Call during a conference and a list of Roll Call DTMF options, see Chapter 4, Roll Call on page 4-73.

Using SilenceIT

The SilenceIT feature is part of the IVR Service used to automatically mute audio participants who placed their phone lines on hold during an On Going Conference, causing all other conference participants to hear the background music. When the audio participant is muted, an IVR message may be played to the conference, informing the other participants that one of the participants was muted due to a noisy line. When muted participants return to the conference, they hear a message informing them that their line was detected as noisy and muted. At this point, the participant can press <9> to listen to a menu offering one of the following options:
Return to the conference unmuted (default) Return to the conference muted Reduce the level of the SilenceIT Sensitivity and return to the conference unmuted Disable the SilenceIT feature for this conference and return to the conference unmuted
SilenceIT IVR messages are described in Table 6-10 on page 6-34. SilenceIT guidelines SilenceIT is supported for Audio Only participants in IVR-enabled Audio Only and Video conferences. SilenceIT is not supported when the participant is moved to the Operator conference (Attended status).
SilenceIT is not supported in recording ports. SilenceIT is not supported in cascading conferences.

Enabling SilenceIT

In some cases, the SilenceIT algorithm is not sensitive enough to the noise level causing speech to be muted, or not muting music and noise. To prevent this problem SilenceIT includes a mechanism that enables the system to measure the audio energy, and based on this measurement, fine-tune the system usage of the SilenceIT algorithm. To reliably measure the audio energy and apply the SilenceIT fine tuning mechanism, speech and noise/music must have sufficient energy, and be consistent across all audio ports.
SilenceIT is enabled by performing the following steps:
Measure the audio energy and based on this measurement, configure a system.cfg flag that enables the SilenceIT option for the MCU. For a detailed description, see Fine Tuning the SilenceIT Algorithm on page 6-63. Enable the SilenceIT option in the IVR Message Service and select the voice messages for this feature. For a detailed description, see Defining a New IVR Message Service, on page 6-17. Optional: Modify the DTMF codes assigned to the SilenceIT options (in the IVR Message Service). For a detailed description, see Defining a New IVR Message Service, on page 6-17. Select the SilenceIT-enabled IVR Message Service in the Conference Properties Settings tab. Select the SilenceIT option in the Conference Properties Settings tab. For a description of new conference definition, refer to Chapter 2.

Setting the Participants Connection to the Conference to Attended Mode
The participant connection to the conference is set to Attended Mode either at the Entry Queue level (if the conference is accessed from the Entry Queue) or at the conference level (if the conference is accessed directly via an IVR Queue).
If a conference is accessed via an Entry Queue and an IVR Service is also assigned to the conference, the attended mode is set only for the entry queue. The Attended Mode is set for a conference only when dial-in participants connect to it directly.
Setting the Entry Queue to Attended Mode
To set the Entry Queue to Attended Mode you define an Entry Queue Service in which the On-hold for Operator Assistance option is selected in the Welcome dialog box.
For a detailed description of the Entry Queue Service definition see Chapter 6, Defining a New Entry Queue Message Service. This Entry Queue Service must be assigned to the Entry Queue which will be used for attended dial-in connections to conferences.
Setting the Conference Connection to Attended Mode
The connection to the conference is set in the IVR Service assigned to the conference by selecting On-hold for Operators Assistance in the IVR Welcome Message dialog box.
This IVR Service is then assigned to the conference to which dial-in participants connect and are assisted by the operator.
Participants Queue Management
The Participants Queue window lists all the participants waiting for the operators assistance. Participants are automatically added to the Participants Queue in the following circumstances:

State Queue Access Time

Table 7-2: Participants Window Columns (Continued) Column Destination Conference Description The name of the destination conference, when known, or the name of the Entry Queue to which the participant has connected. The conference name is known when the participant was connected to the conference and is moved from the conference to the Participants Queue or the Operator conference. For example, when the participant has requested assistance. The login name of the operator who is assisting the participant. This information is useful when there are several operators logged into the same MCU from different computers. The number the participant has dialed. Usually identifies the dial-in number assigned to the Entry Queue or Meeting Room. Indicates whether the participant status is defined as VIP.

Operator

Called Number
The Participants Queue window can be moved to any position on screen and you can configure its size as you can do with the MGC Manager Main Window and the Templates window.
The new placement of the window at the time you close the MGC Manager application is saved for the next time you start MGC Manager - it is displayed in the same location.
Participants Queue Toolbar
The Participants Queue toolbar is enabled when an Operator Conference is running and a Participant icon or Operator icon is selected. The Participants Queue toolbar contains the following buttons:
Table 7-3: Participants Queue Toolbar Buttons Button Function Attend Participant Place Participant on Hold Move to Home Conference Description Moves the participant to the Operator conference for operators assistance. Places the attended participant on Hold. The participant hears an IVR message while on hold. Moves the participant to the Home (destination) conference.
Participant Queue Filter Toolbar
The Participant Queue Filter toolbar options enable displaying the list of participants who are waiting to be connected to the conference, according to selected criteria.
Table 7-4: Participant Queue Filter Toolbar Buttons Button Function Participant Queue Filter List Participant Queue Filter Delete Filter Description Lists the Participant Queue filters currently defined in the system. Opens the Participants Queue Filter dialog box where you define a new Participants Queue Filter. Deletes the selected Participant Queue Filters.
Using Participants Queue Filters You can determine the types of participants to be displayed in the Participants Queue window by creating filters that set criteria according to which participants appear in the list. Use the Participants Queue window to view participants connecting to a specific Entry Queue according to the Entry Queues dial-in number, or according to a specific status. Filters may be used in two modes: when you are connected to the database and locally without logging into the database. When you are connected to the database, filters created and saved in the past may be used for the current session. If you are not connected to the database, you can only create a filter to be used immediately and locally - without being able to save the filter for future use or add it to the list of filters. Two types of filters may be defined: Personal Filters and Public Filters. Personal Filters are created by operators for their personal use. Public Filters can only be defined by a database user with permission to create Public filters and who has logged into the database.

Alternatively, press the selected shortcut key combination as it appears on the Hold button (the default shortcut key is <F4>). When you place a participant on hold who is the last participant in the Participants Queue, the following message appears:
Click Yes to attend a participant that was placed on hold. Click No to leave the participant on hold in the Participants Queue.
Operator Joining a Conference An operator can join a conference for a short announcement or to check the conference status. To join a conference as operator: In the Conferences box of the Attended Participant window, select the conference you want to join, and then click the Join button in the Operator box.
The operator joins the selected conference. Attended participants remain in the operator conference until the operator returns to the operator conference and moves them or places them on hold. To end the Join state of the operator: In the Operator box of the Attended Participant window, click the End Join button. The operator returns to the Operator conference.
Managing Attended Participants from the Browser, Status and Monitor Panes
The same operations that can be performed in the Participants Queue Window can also be performed when selecting participants in the Browser, Status and Monitor panes, using the following methods:
Using the participant right-click menu Using the Attended Participant toolbar Using Shortcut keys Using drag and drop
Selecting the Participants to Manage
The participants can be selected from the following places:
Browser, Status, and Monitor pane, On Going Conference list
Browser and Status pane, Participants Queue list

Appendix A: Glossary

This appendix lists the terms and abbreviations that relate to the MGC functionalities and technologies, and are commonly used in the MGC Manager documentation.
Abbreviation/ Term AMI Asynchronous
Explanation Alternate Mark Inversion. A T1 line coding format, inverting alternate ones. A transmission method used by dial up modems. Data is transmitted using a start bit at the beginning of a character and a stop bit at the end. The time interval between characters may be of varying lengths. Asynchronous Transfer Mode. High speed (up to 155 Mbps) high bandwidth network that integrates voice, video and data. ATM provides connectivity to LANs, WANs, private networks and sub-networks. ATM supports applications requiring high transmission speeds, large transmission capacities, and bandwidth on demand. Used to mix multiple audio inputs and to output composite audio to each of the endpoints connected to a conference. Bipolar 8-Zero Substitution. A T1 line coding format substituting each group of eight consecutive zeros with an established pattern. See also T1 line.

Audio Bridge B8ZS

Abbreviation/ Term Bandwidth
Explanation Defines the information carrying capacity of a channel. In analog systems, it is the difference between the highest frequency that a channel can carry and the lowest, measured in hertz. In digital systems, bandwidth is measured in bits per second The larger a connection's bandwidth, the more data can be transmitted in a given amount of time, allowing for greater video resolution and more sites in a conference. See Line Rate. Bitrate Allocation Signal. BAS codes are used to exchange information about capabilities and commands between devices at opposite ends of a digital video connection. Bearer Channel. A channel in a span or in a group of spans, that carries audio-visual data.The ISDN circuit-switched bearer channel is capable of transmitting 64 Kbps of digitized information. Bandwidth ON Demand INterpolarity Group. A transmission protocol that aggregates two 64 Kbps B channels to function as one 128 Kbps channel. When using several BRI channels, Bonding means that only one D-channel serves all BRI channels, while the remaining D-channels are used for data transfer. See also: BRI. Bits and kilobytes per second; a unit of bandwidth, that is the amount of data that can flow during one second over a communications line (using a transmission medium). 1 Kbps=1000 Bps Basic Rate Interface. A type of ISDN connection for transmitting data, consisting of 3 channels: two B-channels (each of 64 Kbps) and one D-channel (16 Kbps). A telephone or other company that provides telecommunication transmission services. The use of two MCUs in a multipoint video conference, allowing for multipoint conferences with more than 12 video participants.
