Modifications The FCC requires the user to be notified that any changes or modifications made to this system that are not expressly approved by VCON Ltd. may void the user’s authority to operate the equipment.
Safety Notice When you use the MediaConnect 6000 system, observe the following safety guidelines:
WARNING Do not operate the computer with any of its covers removed (including main cover, bezels, filler brackets, front-panel inserts, and so on). Do not remove the cover of the computer or any other accessories. Refer all servicing only to the local VCON distributor or other VCON-certified technicians. To help avoid damaging the computer, make sure that the voltage selection switch on the power supply is set to match the AC power available at your location: T
115 V/60 Hz in most of North and South America and some Far Eastern countries such as Japan, South Korea and Taiwan
T
230 V/50 Hz in most of Europe, the Middle East and the Far East.
Make sure the monitor and attached accessories (VTOP PTZ camera, VCR, document camera, and so on) are electrically rated to operate with the AC power available in your location. To help avoid possible damage to the system boards, wait 5 seconds after turning off the system before disconnecting a device from the computer. To help prevent electric shock, plug the computer’s and accessories’ power cables into properly grounded power sources. These cables are equipped with three-prong plugs to help ensure proper grounding. Do not use adapter plugs or remove the grounding prong from a cable. If you must use an extension cable, use a three-wire cable with properly grounded plugs. Make sure that nothing rests on the computer system’s cables and that the cables are not located where they can be stepped on or tripped over. Keep food and liquids away from the system or accessories. Keep the computer away from radiators and heat sources. Also, do not block cooling vents. Avoid placing loose papers underneath the computer, and do not place the computer in a closed-in wall unit or on a bed, sofa, or rug. iv

For Users in Canada NOTICE: The Industry Canada Label identifies certified equipment. This certification means that the equipment meets telecommunications network protective, operational and safety requirements as prescribed in the appropriate Terminal equipment Technical Requirements document(s). The Department does not guarantee the equipment will operate to the user’s satisfaction. Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations. Repairs to certified equipment should be coordinated by a representative designated by the supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment. Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.
CAUTION Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate. NOTICE: The REN for this device is X.X. The Ringer Equivalence Number (REN) assigned to each terminal device provides an indication of the maximum number of terminals allowed to be connected to a telephone interface.

Pour les utilisateurs au Canada AVIS: L’étiquette d’Industrie Canada identifie le matériel homologué. Cette étiquette certifie que le matériel est conforme aux normes de protection, d’exploitation et de sécurité des réseaux de télécommunications, comme le prescrivent les documents concernant les exigences techniques relatives au matériel terminal. Le Ministère n’assure toutefois pas que le matériel fonctionnera à la satisfaction de l’utilisateur. Avant d’installer ce matériel, l’utilisateur doit s’assurer qu’il est permis de le raccorder aux installations de l’entreprise locale de télécommunication. Le matériel doit également être installé en suivant une méthode acceptée de raccordement. L’abonné ne doit pas oublier qu’il est possible que la conformité aux conditions énoncées ci-dessus n’empêche pas la dégradation du service dans certaines situations. Les réparations de matériel homologué doivent être coordonnées par un représentant désigné par le fournisseur. L’entreprise de télécommunications peut demander à l’utilisateur de débrancher un appareil à la suite de réparations ou de modifications effectuées par l’utilisateur ou à cause de mauvais fonctionnnement. Pour sa propre protection, l’utilisateur doit s’assurer que tous les fils de mise à la terre de la source d’énergie électrique, des lignes téléphoniques et des canalisations d’eau métalliques, s’il y en a, sont raccordés ensemble. Cette précaution est particulièrement importante dans les régions rurales.
AVERTISSEMENT
L’utilisateur ne doit pas tenter de faire ces raccordements lui-même; il doit avoir recours à un service d’inspection des installations électriques, ou à un électricien, selons le cas.
AVIS: Le IES assigné à cette équipment est X.X. L’indice d’équivalence de la sonnerie (IES) assigné à chaque dispositif terminal indique le mombre maximal de terminaux qui peuvent être raccordés à une interface. La terminaison d’une interface téléphonique peut consister en une combinaison de quelques dispositifs, à la seule condition que la somme d’indices d’équivalence de la sonnerie de tous les dispositifs n’excède pas 5.

WELCOME TO MEDIACONNECT 6000
Welcome to VCON’s MediaConnect 6000 series – high quality, TV-based videoconferencing and collaboration system. The MediaConnect 6000 system is friendly, yet sophisticated, with high video and audio quality and powerful videoconferencing capabilities.
1.1
MediaConnect 6000 Models
The MediaConnect 6000 series includes two product configurations: MediaConnect 6000
LAN and ISDN compact TV-based Videoconferencing System
MediaConnect 6000Pro
LAN and ISDN complete Rollabout Videoconferencing system, including a large TV monitor and a specially designed cart.
The products are available in the following models, supporting different communication interfaces and bandwidths: Model 1
Provides a single ISDN Basic Rate Interface (BRI) connection at 128 Kbps and a LAN connection for up to 1.5 Mbps.
Model 3
Provides three ISDN BRI up to 384 Kbps, LAN connection up to 1.5 Mbps, and support for VCR playback and recording.
MediaConnect 6000 and 6000 Pro models meet technical recommendations prescribed in the H.323 and H.320 ITU-T standards for networking. T H.323 is the worldwide accepted standard for transmitting video, audio and
data across local-area and wide-area networks (LANs and WANs) using the Internet Protocol (IP). T H.320 is the worldwide accepted standard for transmitting video, audio and

1.2
MediaConnect 6000 Features
MediaConnect 6000 systems provide several distinctive attributes and features which make them ideal solutions for group videoconferencing environments. Version 2.1 provides the following enhancements and abilities: T
Superior video and audio quality over IP and ISDN Videoconferences may be transmitted over IP at a bandwidth up to 1.5 Mbps.
T
Media Xchange Management™ Support VCON’s Media Exchange Manager™ (MXM) provides centralized management of an organization’s videoconferencing network. If MediaConnect 6000 logs into an MXM server, it receives gatekeeper services, bandwidth management, and telephony functions, such as call forwarding, call pickup and IP-to-ISDN connection through a gateway.
T
Data and Application Sharing All parties can see and work together on the same program, and transfer files to each other. Internal data sharing requires the connection of a VGA monitor, in addition to the main TV monitor, to the MediaConnect 6000. External data sharing requires the additional connection of a second computer to the MediaConnect 6000.
T
Quality of Service (QoS) VCON’s PacketAssist™ Architecture preserves optimum quality of your videoconference according to available bandwidth and network traffic. MediaConnect 6000 applies mechanisms such as IP Precedence to prioritize the video, audio and control bits, and DiffServ to transfer packets according to the MediaConnect 6000’s specific needs.
T
Interactive Multicast Using VCON’s Interactive Multicast, all parties in the videoconference see and hear the same video, audio, and data sharing. Control over these streams, as a whole or separately, may be switched between the conference manager (Chair), and the other parties (Participants). The result is greater centralized control during a multipoint conference over IP, combined with interaction among all parties.
T
H.323 and H.320 Multipoint Videoconferencing In multipoint videoconferencing through a Multipoint Control Unit (MCU), the parties may see and switch among the video of several participants, through functions such as Continuous Presence and Voice-Activated Switching.

QoS Settings VCON’s PacketAssist™ Architecture simplifies Video over IP bandwidth management and delivers true Quality of Service (QoS) for IP networks. PacketAssist automatically adapts video meeting transmissions to current network conditions, while ensuring optimal video and audio performance. For example, if MediaConnect detects the possibility of network congestion, it automatically decreases the transmission rate until it finds the optimal point for continuing transmission, while maintaining good video quality at this lower rate. A message appears on the screen stating that the system is adjusting itself.

More Video Options MediaConnect 6000 offers advanced video features, such as still image control and control over the type of video compression to be used during ISDN calls. Sending/Requesting Still Images You can send a still image, which is a captured frame from the local video, to the remote party. For example, you can display a paper on an optional document camera and then send a still image of this paper. While the remote party is viewing the still image, you can take the paper off the camera and prepare a new one. You can also take still images of the remote party’s video. For example, you could ask the remote party to hold an object up to the camera and then take a still image of it. Then you could study this object while continuing to communicate. Sending and receiving still images is only available in videoconferences between parties that use at least one TV monitor. If any of these parties has only a VGA monitor (such as the MediaConnect 8000 Single Monitor configuration), this feature is disabled. ³ To send a still image T

VIDEO OVER IP
VCON provides quality videoconferencing products which conform to the H.323 recommendation for network communications over IP, set by the ITU-T. This chapter summarizes the H.323 Recommendation, its equipment and services, and describes the roles and uses of the different components of an H.323 Video over IP solution. Video over IP is a new and sophisticated technology. If you come to an unfamiliar term in this chapter, you can find the definitions in the glossary on the VCON website (go to www.vcon.com, click the links to Publications and Glossary).
6.1
H.323 Recommendation
Recommendation H.323 describes equipment that provides services for packetbased multimedia communications.
Equipment H.323 equipment includes: T Conferencing endpoints T Gateways T Gatekeepers T Multipoint Conference Units (MCUs).
Services The main objective is for people to conference with each other, no matter how far apart they are physically located, or how differently their systems were designed by their manufacturers. The H.323 Recommendation details how the components of a Video over IP system cooperate to fulfill this task.

Chapter 6 Video over IP
Packet Based In a packet-based network, multimedia streams are broken into packets, sent over the network through various routes, and reassembled into streams when they reach their destination. Packet-based bandwidth is dynamic—it depends on how busy and capable the network routes are at the time of the call. IP (Internet Protocol) is a set of rules (a protocol) governing how packets are sent and received over a packet-based network. Packet-based networking greatly differs from circuit-switched networking (used for ISDN lines), which opens a dedicated route by turning on switches along the way to make a permanent circuit between the caller and the party being called for the duration of the call. ISDN bandwidth is fixed—other calls are not allowed to use the same circuits until the call has ended. Although ISDN networking offers a fixed bandwidth, and therefore a Quality of Service unavailable to IP, there are certain advantages to packet-based networking:
6-2
T
Packet-based networks use the existing network and infrastructure. This means lower costs for setup and maintenance. ISDN lines are expensive to buy, install, manage and service.
T
While packet-based endpoints connect to the existing network at the office, ISDN-based endpoints require separate installations for each.
T
Only IP can integrate interactive and streaming video into a single solution, such as VCON’s Interactive Multicast.

Multipoint Conference Units (MCUs)
H.323 conferencing systems can communicate with each other in point-to-point conferences, but if we add a Multipoint Conference Unit (MCU) to the LAN, several users can join in a single video meeting. An MCU is a device that centralizes the connections and characteristics of a multipoint video meeting. To join multipoint meetings through an MCU, a system must be registered with a gatekeeper which is registered with the same MCU. A system enters a meeting by either calling the MCU (dial its IP address, as you would any endpoint) or answering a call from the MCU.
ViGO Basic
ViGO Professional
MCU Desktop Conferencing System (VCON/non-VCON)

During the call, participants will see either the person currently talking (VoiceActivated Switching) or a composite screen of all active participants (Continuous Presence). For non-VCON endpoints, the MCU is the only available solution for fully interactive multiparty video meetings. VCON offers an affordable software solution for multiparty conferences: Interactive Multicast. If your system does not support it, and you want to add it, contact your local VCON distributor.

Gatekeeper
Gatekeeper Zone: all network equipment registered and managed by the Gatekeeper
Every conferencing system that registers with the Gatekeeper provides its User Number (also called an E.164 Number) and a User Name (also called an H.323 Alias). The Gatekeeper keeps a database so it can map between the IP address, the User Number and the User Name of each system. Therefore, you can dial these numbers or names instead of IP addresses. Example
Explanation
IP Address
122.29.65.203
Dynamic address assigned by a network server.
User Number
290
User selected number, such as a phone number.
User Name
Boardroom
User selected name, or the name of the system.
User Numbers and Names are static. They do not change, as long as a system remains registered with the same Gatekeeper. IP addresses are usually dynamic; they may change without notification. Ask your system administrator what your User Number and Name are.

VCON MediaConnect 6000 User’s Guide
Chapter 6 Video over IP
Gatekeepers also provide access control, which means that you cannot communicate with non-registered systems. Fortunately, Gatekeeper zones are not limited to LAN segments; they can connect international WANs. If you want to call someone who is registered with another Gatekeeper, ask the system administrators to set the Gatekeepers as neighbors. Neighboring Gatekeepers share databases; their endpoints can contact each other. Make sure that your conferencing contacts are registered either with your Gatekeeper, or with one that neighbors it.

MULTI-PARTY CONFERENCING WITH INTERACTIVE MULTICAST
Interactive Multicast for multi-party videoconferencing is a software alternative to the expensive MCU (see Chapter 8 for more information on MCUs). Interactive Multicast uses bandwidth more efficiently than an MCU does, and it does not limit the number of users in a session or the number of sessions per license; most MCUs do. During an Interactive Multicast, identical video streams, audio streams, and data application sharing packets are sent from one party to multiple parties. The initiating party (Chair) calls one or more parties (Participants) at the start of the meeting and controls its progression. All parties receive identical transmissions. MediaConnect provides the capability to carry out Interactive Multicast video meetings over a Local Area Network (LAN), in which the Chair and all Participants may be seen and heard during the duration of the meeting. Interactive Multicasts can proceed in the form of a lecture or demonstration, in which Participants’ participation is restricted and controlled by the Chair, or as a free discussion, in which everyone has the right to be seen and heard without the need to receive permission from the Chair. During the meeting, the Chair can decide to receive questions from Participants or to grant the floor temporarily. In addition, other Participants may join in an Interactive Multicast while it is in progress. If data sharing is active, all Participants receive identical copies of any application opened by the Chair. If the Chair permits, Participants may collaborate on the application. The Chair and Participants can also send and receive files.

MULTI-PARTY VIDEOCONFERENCING THROUGH AN MCU
An MCU (Multipoint Control Unit) is a machine which enables multi-party videoconferencing. MediaConnect supports both H.320 and H.323 MCUs. This chapter explains multi-party videoconferencing through an MCU.
8.1
Joining an H.320 MCU Videoconference
You can join a multi-party videoconference through an MCU either by answering an incoming call from the MCU, or by calling the MCU session. You can call an MCU session just as you would call another ISDN number. However, before you attempt to call, consult with the network administrator or the remote parties to make sure that you are calling the MCU number currently assigned to you. Each party, yourself included, calls the address or ISDN number of the MCU (or a set of ISDN numbers, if you are calling to more than one BRI). The MCU collects the calls and mixes them to create the multi-party videoconference. ³ To join a multi-party videoconference T
Dial the MCU from the Phone Book or manually.

8.2
Managing the MCU Videoconference
An important feature of managing an MCU videoconference is controlling which of the multiple participants is seen and heard. T
The session can be managed by the MCU itself, either by Continuous Presence or by Voice-Activated Switching. This configuration must be defined in the MCU’s session properties. Continuous Presence Voice-Activated Switching
Up to four participants in an MCU session are viewed and heard simultaneously. The participants see the video of the participant whose audio signal is strongest. For example, the non-speaking participants see the person speaking.
Video Display of Continuous Presence T
Participants can view the full-screen of a selected party. Participant View overrides Continuous Presence and Voice-Activated Switching.

The Chair can force one party’s video to be broadcast to all the participants. A Chair Force overrides Continuous Presence, Voice-Activated Switching, and Participant View.

Users that are registered with the MXM receive all the regular Gatekeeper services, plus more call exchange services from the MXM features. One Gatekeeper service is zone control: registered users can call each other, but calls to and from an unregistered user are rejected. Another service that users receive is address translation. MXM-registered users can use the regular Gatekeeper H.323 Alias, which you choose for yourself when you configure MeetingPoint, and a User Number. The MXM assigns every registered user a new User Number, to ensure that every user has a unique number, which overrides any User Number you chose for yourself during MeetingPoint configuration. Supported Address Type

DNS Name “johns.best.com”
Every registered user receives a User Number (directory number). The MXM keeps a directory of numbers and assigns an available number to every new user. This number overrides user-determined User Numbers. If the user is registered with a Domain Name Service server as well as the MXM, you can send DNS names.
In this version of the MXM, dialing and receiving videoconferencing calls are only available among users registered in the same MXM. Calls to and from unregistered users are rejected.

Call Pickup Call Pickup enables you to answer a videoconferencing call intended for another user. To do this, the MediaConnect 6000 must be given Pickup Permission for the destination user by the administrator in the MXM Administrator application. The available types of call pickup are Specific and Non-specific.
T Specific - Picking up a call that’s intended for another specific user. For example, if the conference room was changed but the caller mistakenly calls the original one, the party in the correct room can pick up that call by entering the specific-pickup code and the original destination number.
T Non-specific - Picking up a call that’s intended for the longest-ringing user for which your user has pickup permission. For example, if the conference room was changed but the caller mistakenly calls the original one, the party in the correct room can pick up that call by entering the non-specific-pickup code.

10 DATA AND APPLICATION SHARING The ability to share and collaborate on data and applications is an important feature of videoconferencing. For example, you and the other parties can exchange files, view a business presentation together, or analyze the execution of another application. MediaConnect 6000 applies the requirements of the ITU-T T.120 (User Data Transmission Using a Multi-Layer Protocol) standard for data conferencing. T.120 defines the use of protocols and services for performing a number of data sharing applications, covering a large number of possible complexities. MediaConnect 6000 provides data and application sharing and collaboration through its own Data Mode, and it supports Microsoft NetMeeting 2.1. Internal data sharing is possible only when a VGA monitor is connected to the system (see “Connecting a VGA Monitor” in Chapter 11). While sharing data during a videoconference, MediaConnect performs a dual function: one is the videoconference, shown on the TV screen; the other is the data sharing, shown on the VGA monitor. Using either data sharing method, you can: T Transfer and receive files T Demonstrate (share) and collaborate on shared applications T Draw together with the other participants on a Whiteboard.
Data and application sharing is available either Internally or Externally. Internal Data Sharing
External Data Sharing
The local MediaConnect system shares data and applications directly from its computer. Either the MediaConnect Data Mode or NetMeeting 2.1 can be used. A second (external) PC or laptop is connected to the local MediaConnect system’s COM2 port through a serial cable. NetMeeting 2.1 runs on the external computer. The local MediaConnect system sends and receives data sharing between the external system and the remote party.

11 USING VOICEFINDER™ VoiceFinder™ is an optional add-on device for the MediaConnect systems, providing almost hands-free communication through automatic and intelligent visual and audio control. VoiceFinder makes videoconferencing easier than ever and closer to real-life face to face meetings with the following features: T Voice Tracking - VoiceFinder locates participants’ voices during a group
discussion and then positions and focuses the camera on the person currently speaking. It is an intelligent system, keeping statistics on current speakers and automatically learning about new ones. VoiceFinder is able to determine who are speakers and what noises to ignore; the camera moves and focuses quickly on the main speakers, but doesn’t move if someone coughs or interjects a word. When multiple participants speak at once for longer than a few seconds, VoiceFinder zooms the camera out to display the entire group. T Voice Transfer - VoiceFinder includes four high-quality microphones that can
replace the traditional wired tabletop microphone. The Voice Transfer feature operates on intelligent algorithms for audio transmission to the remote side. It also includes AEC (Automatic Echo Cancellation), AGC (Automatic Gain Control) and ANS (Automatic Noise Suppression). Voice Tracking and Voice Transfer are independent features. You can initiate one and not the other, or use both at once.
NOTE The Voice Transfer feature is available only for MediaConnect 6000 Model 3.

Application Viewing In personal conferencing, the users sharing the application can see every keystroke or mouse movement made by the one user who is running the application. The other users have no control over the application. ATM. Asynchronous Transfer Mode A network type that combines the advantages of both packet-switching and circuitswitching network architectures. ATM transfers multimedia with a Quality of Service similar to circuit-switched networks, and makes as efficient use of bandwidth as packet-switched networks. Audio Signals that carry sounds. Audio Bridge Equipment that mixes multiple audio inputs. Then it returns the composite audio result to each station. Automatic Bandwidth Adjustment Algorithm for automatically varying the bit rate of the transmission according to network behavior. B-Channel. Bearer Channel An ISDN circuit-switched channel. B-Channels transmit 64 Kilo-bits per second of digitized information (or 56 Kbps on Restricted networks). B-Channels are logical divisions of ISDN bandwidth; they are not physical wires within the ISDN cable. B-ISDN. Broadband Integrated Services Digital Network A networking standard, incorporating the existing ISDN switching, signaling, multiplexing and transmission standards into a higher-speed specification that will support transmission of different types of information around the public switched network.

Bit rate The number of bits of information transmitted over a channel in a given second. Typically expressed as “bps”. Bonding. Bandwidth ON Demand Interoperability Group Method of unifying ISDN B-channels to attain higher data rates. Bonding synchronizes the B-channels to transmit as one stream. When you set the data rate you want, Bonding ensures that as many channels as are needed to reach that rate are dialed. It is advantageous when calling long distance, when the delay between separate BRI lines without Bonding would make the call impossible. Another advantage is that a Bonding call needs only one number; you dial only one ISDN number to connect at the data rate you want. A disadvantage to Bonding is that the videoconference cannot start until the whole unit of B-channels is connected. Without Bonding, you could start the videoconference as soon as the first channel was connected. Another disadvantage is that with Bonding, either all the channels are able to connect or the videoconference cannot be made. Without Bonding, the videoconference could continue even if one channel was disconnected. bps Bits per second, a unit of measurement of the speed of data transmission and thus of bandwidth. BRI. Basic Rate Interface In ISDN there are two interfaces, the BRI and the PRI (Primary Rate Interface). The BRI offers two circuit-switched B-Channels (bearer) of 64 kbps each and one packet-switched 16 kbps D-Channel (delta) that is used for exchanging signals with the network. Bridge In videoconferencing, a bridge connects three or more conference sites so that they can simultaneously communicate. See also: MCU (Multipoint Control Unit). A networking bridge is a device that interconnects LAN segments to extend the physical LAN environment. An audio bridge is a device used in audio conferencing to connect multiple voice calls so that multiple participants can hear and be heard. Broadcasting In packet-switched networks, this means sending a packet to all users connected to a videoconference session.

Call Multimedia communication between two or more H.323 endpoints. Call Signaling Channel A reliable channel used to convey call setup messages. Caller ID An identification (number, name) of the party being called. This identification is of interest when you transfer or forward a call. For example, when an unanswered call is forwarded to a voice messaging system, the called-ID of the original call is used to locate the mailbox of the called party. CCITT Consultative Committee for International Telegraphy and Telephony. As of 1994 known as the International Telecommunications Union. See ITU. Centralized Multipoint Conference A call in which all participating terminals communicate in a point-to-point fashion with an MCU. CIF Common Intermediate Format, an optional part of the ITU-T's H.261 and H.263 standards. CIF specifies 288 non-interlaced luminance lines, that contain 176 pixels. CIF is to be sent at frame rates of 7.5, 10, 15, or 30 per second. When operating with CIF, the number of bits that result can not exceed 256 K bits (where K equals 1024). Circuit-switched An ISDN bearer service that provides a 64 kbps (sometimes 56 kbps) path between two users for the duration of the call. The term is also used for the networks with behavior similar to ISDN. CODEC A sophisticated digital signal-processing unit that takes an analog input and converts it to digital on the sending end. At the receiving end, another codec reverses this by reconverting the digital signal back to analog. Codec is a contraction of code/decode (some experts in the video industry assert it also stands for compress/decompress). A codec takes the form of a set of hardware or software components, or a combination of both.

Compression Reducing the representation of the information, but not the information itself. Reducing the bandwidth or number of bits needed to encode information or encode a signal, typically by eliminating long strings of identical bits or bits that do not change in successive sampling intervals (e.g., video frames). Compression saves transmission time or capacity. It also saves storage space on storage devices such as hard disks, tape drives, and floppy disks. D-Channel A logical division of bandwidth within an ISDN BRI. The D-Channel carries control information, such as transformation confirmation, which gives ISDN its Quality of Service (QoS). One D-Channel is paired with two B-Channels in regular BRI videoconferencing; but the D-Channel is not created when the call uses Bonding. Data Sharing The ability of two or more remote parties to transfer files, and to work together on a software application (even if the same application is not installed at all parties). During data sharing, the owner of the application controls it while the others observe. If the owner enables application collaboration, any participant may take control of the software. Decentralized Multipoint Conference Conference in which the participating terminals multicast to all other participating terminals without an MCU. Document Sharing See Whiteboard and Application Sharing. Dual Monitor An optional configuration for VCON products that adds a second television screen to the basic package, allowing remote video to be shown on one screen while local video is shown on another. E1 Digital transmission format, used mainly in Europe and Asia, for dedicated connections between PBXs and central telephone exchanges. E1 lines can transfer data at a maximum rate of 1,928,000 bps.

Endpoint A Terminal, Gateway, or MCU. Ethernet A LAN running at 10 or 100 Mbps. Every Ethernet endpoint has the capability of sensing whether the cable is active or idle. When idle, an endpoint may transmit. Ethernet endpoints are cheaper than Token Ring endpoints, but Ethernet networks generate more noise and collisions. Ethernet switch A device that provides every sender-receiver pair on an Ethernet network with the full bandwidth available instead of dividing the bandwidth among all users. Full-duplex Simultaneous transmission of data in two directions (send and receive). Compare to half-duplex, where data can only be sent or received in one direction at a time. G.711 An ITU-T Recommendation entitled, "Pulse Code Modulation (PCM) of Voice Frequencies". G.711 defines how a 3.1 kHz audio signal is encoded at 64 kbps using Pulse Code Modulation (PCM) and either Mu-law (US and Japan) or A-law (Europe). This standard is used for videoconferencing when no other standard is equally supported by all of the endpoints. G.722 An ITU-T Recommendation that defines how a 7.5 kHz audio signal is encoded at a data rate of 64 kbps. This standard gives high quality results, but takes more bandwidth. G.723 An ITU-T Recommendation entitled, "Dual Rate Speech Coder for Multimedia Communication Transmitting at 5.3 and 6.4 kbps". This standard offers good quality results for low bitrates. G.728 An ITU-T Recommendation for audio encoding using Low Delay Code Excited Linear Prediction (CELP). The bandwidth of the analog audio signal is 3.4 kHz whereas after coding and compression the digitized signal requires a bandwidth of 16 kbps. This standard gives good quality results for low bitrates. Gatekeeper A Gatekeeper is a software utility used for managing conferencing over IP according to the H.323 standard. The Gatekeeper provides certain services to the endpoints registered into its zone: access control, address translation, gateway management, and call signaling. VCON MediaConnect 6000 User’s Guide

Gateway The gateway allows H.323 systems to interoperate with other H.32x products. For instance, the gateway could connect an H.323 endpoint with an H.320 (ISDNbased) system. Most H.323 gateway implementations are concerned with linking H.323 and H.320 systems. H0 channel An aggregate of six B-Channels and one D-Channel. Its bandwidth and speed is similar to Bonding 6 channels, but it does not add codec synchronization. H.221 Defines Bonding. H.221 specifies synchronous operation in which the coder and decoder synchronize timing. H.222 This ITU-T Recommendation specifies generic coding of moving pictures and associated audio information. H.223 Part of the ITU-T's H.324 standard specifying a control protocol for multiplexing. H.231 A Recommendation added to the ITU-T's H.320 family specifying multipoint control unit used to bridge three or more H.320 compliant codecs together in a multipoint conference. H.233 A multiplexing Recommendation that is part of the ITU-T family of video interoperability Recommendations. The Recommendation specifies how individual frames of audiovisual information are to be multiplexed onto a digital channel. H.242 Part of the ITU-T's H.320 family of video interoperability Recommendations. H.242 specifies the protocol for establishing an audio session and taking it down after the communication has terminated. H.245 Part of the ITU-T's H.323 and H.324 families defining control of communications between multimedia terminals. H.261 The ITU-T's Recommendation that allows dissimilar video codecs to interpret how a signal has been encoded and compressed, and to decode and decompress that signal. It also defines two picture formats: CIF and QCIF.

H.263 The ITU-T's Recommendation that allows dissimilar video codecs to interpret how a signal has been encoded and compressed, and to decode and decompress that signal. This recommendation includes additional techniques for lower bitrate, approximately between 15 and 20 Kbps. H.320 An ITU-T standard including a number of individual recommendations for coding, framing, signaling and establishing connections (H.221, H.230, H.321, H.242, and H.261). It applies to point-to-point and multipoint videoconferencing sessions and includes three audio algorithms, G.711, G.722 and G.728. This standard describes videoconferencing over ISDN lines and circuit-switched networks. H.323 The H.323 extends the H.320 to Intranet, Extranet or Internet over packet-switched networks: Ethernet, Token-Ring, and others that may not guarantee QoS. It also specifies procedures for videoconferencing over ATM including ATM QoS. It supports both point-to-point and multipoint operations. H.323 Alias User logical name used for remote party calling. Translated by Gatekeeper to the network address. H.324 An ITU-T standard that provides point-to-point data, video, and audio conferencing over analog telephone lines (POTS). It can incorporate H.261 video encoding, but most implementations will probably use H.263, a scalable version of H.261 that adds a 128-by-96 Sub-QCIF (SQCIF) format. Because of H.263's efficient design, it may produce frame rates much like those of today's ISDN H.320 systems through inexpensive hardware-assisted modems. The H.324 family includes H.223, a multiplexing protocol. H.245, a control protocol, T.120, a suite of audiographics protocols and V.34, a modem specification. Interoperability The ability of a system or a product to work with other systems or products without special effort on the part of the customer. The trend toward embracing standards has greatly furthered the interoperability process. Inverse Multiplexing See Bonding. IP. Internet Protocol The most popular network protocol in corporate and public networks. May be used by H.323 endpoints for audio, video, and data packets transfer.

ISDN. Integrated Services Digital Network ISDN is a digital telephone service that can be installed by the local telephone company to replace the old analog local loop (the connection to the telephone company's nearest central switching office) with a digital line. As long-distance lines are usually digital already, replacing the local loop with an ISDN line provides "end-to-end" digital service. Two types of ISDN are: BRI and PRI. ITU. International Telecommunications Union One of the specialized agencies of the United Nations that is composed of the telecommunications administrations of 113 participating nations. Founded in 1865 before telephone were invented as a telegraphy standards body. It now develops international standards for interconnecting telecommunications equipment across networks. Kbps Kilobits per second - one thousand bits per second. LAN. Local Area Network A network of computer and other devices for communication within a restricted geographic area, such as a building or a campus. All LAN terminals are connected to a single common highway or bus. LAN types can be either Ethernet or Token Ring. Mbps Megabits per second or approximately one million bits per second. Multicasting Sending a packet that can be received by multiple recipients, all of whom are listening on a single multicast address. Multiplex A method of transmitting multiple signals onto a single circuit so that each can be recovered intact. Multiplexer Electronic device that enables multiple signals to share a single communications circuit. Multiplexing The process of combining multiple signals into a single circuit using various means. Multipoint Communication configuration in which several terminals or stations are connected. Compare to point-to-point where communication is between two stations only.

MCU. Multipoint Control Unit A bridge that connects more than two parties in H.323 and/or H.320 videoconferences. MP. Multipoint Processor A node that provides for the processing of audio and video streams in an MCU. The MP provides for the mixing, switching, transcoding, or other processing of media streams under the control of the multipoint controller (MC). Network A group of nodes (computers, servers, or other devices) connected by communications equipment for exchanging information. Connection can be permanent, via cable, or temporary, through telephone or other communications links. The transmission medium can be physical (copper, wire, fiber optic cable etc.) or wireless, for example via satellite. PSN. Packet-Switched Network A network designed to carry packets of information, such as an IP LAN segment or the Internet. POTS. Plain Old Telephone Service Conventional analog narrowband telephone line using twisted-pair copper wire for transmitting voice calls. PRI. Primary Rate Interface. An ISDN interface (see also BRI for the other interface). PRI offers various logical assignments to multiple physical cables. For example, PRI could divide the 24 channels of a T1 cable in various ways, such as 23 B-Channels and 1 DChannel, or 11 BRIs and 1 D-Channel. Q.931 Protocol for setup, control and termination of calls. Q.931 messages and procedures are usually carried by D-channels in an ISDN-BRI. QoS. Quality of Service A mechanism that ensures optimal video and audio performance during IP videoconferencing by prioritizing the usage of available network resources. According to the priority settings, video, audio, and control packets are transferred in accordance to current network conditions. RAS Channel An unreliable channel used to convey the Registration, Admissions and Status messages and bandwidth changes between two H.323 entities through a Gatekeeper.

Reliable Transmission Connection-oriented data transmission which guarantees sequenced error-free, flow-controlled transmission of messages to the receiver. RSVP. Resource Reservation Protocol IETF specification. Allows applications to request dedicated resources. RTP/RTCP. Real-Time Transport Protocol/Real-Time Control Protocol IETF specification for audio and video signal management. Allows applications to synchronize and spool audio and video information. RTCP maintains QoS. Router Equipment that facilitates the exchange of packets between autonomous networks (LANs and WANs) of similar architecture. Routers move packets over a specific path or paths based on the packet's destination, network congestion and the protocols implemented on the network. Switch A device that establishes, monitors, and terminates a connection between devices connected to a network. Switching The process of setting up a connection between an input and an output. It enables a subscriber to establish communications with multiple parties by sending their address to the switch, which will then attempt to make a connection. SCN. Switched Circuit Network A public or private switched telecommunications network such as GSTN or ISDN. Switch Type The type of ISDN network you are connected to. This information is available from the ISDN provider and provided to the buyer when purchasing an ISDN line. T.120 The ITU-T's "Transmission Protocols for Multimedia Data", a data sharing/data conferencing specification that lets users share documents during any H.32x videoconference. Like H.32x specifications, T.120 is an umbrella Recommendation that includes a number of other Recommendations. Data-only T.120 session can be held when no video communications are required, and the standard also allows multipoint meetings that include participants using different transmission media. The mandatory components of T.120 include recommendations for multipoint file transfer and shared-whiteboard implementation.

TCP. Transmission Control Protocol A reliable transport layer on top of IP. Teleconferencing The use of telecommunications links to provide audio, video and graphics capabilities. These systems allow distant workgroups or individuals to meet. An endpoint which provides for real-time, two-way communications with another terminal. Token Ring A LAN type (see Ethernet for the other type) that uses a token (a signal) passed around all stations, telling each station whether the network is busy or idle. When a station receives an idle token, it may transmit. A Token Ring LAN is more controlled, and uses bandwidth more efficiently than an Ethernet LAN; but Token Ring endpoints are more expensive than Ethernet endpoints. UDP. User Datagram Protocol An unreliable but faster transport layer on top of IP. Videoconferencing transmits video, audio and data by UDP packets. Unicast Application of conferencing, usually over packet-switched networks, where only one user receives data. In contrast to this, multicast application, where data is received by more than one user. Unreliable Transmission Connection-less transmission which provides best-effort delivery of data packets. Messages transmitted by the sender may be lost, duplicated, or received out of sequence. User Alias (H.323 Alias) A character string given to an H.323 endpoint by the user or the system administrator. If this endpoint is registered with a Gatekeeper, the Gatekeeper can translate the User Alias into the endpoint’s IP Address. Therefore, calls can be made by entering someone’s User Alias in place of their IP Address.

User Number (E.164 Number) A numeric string given to an H.323 endpoint by the user or the system administrator. If this endpoint is registered with a Gatekeeper, the Gatekeeper can translate the User Number into the endpoint’s IP Address. Therefore, calls can be made by entering someone’s User Number in place of their IP Address. If an ISDN endpoint wants to contact this H.323 endpoint through a Gateway, the ISDN user must use the User Number to contact the H.323 endpoint. The ISDN user enters the destination address as follows: V.35 The physical connection between a network access device (such as a modem) and a packet network at data rates higher than 19.2 Kbps. V.35 may use the combined bandwidths of several telephone circuits as one group. Videoconferencing A collection of technologies that integrate video with audio, data, or both to convey in real-time over distance for meeting between dispersed sites. Video Server A specialized file server with enormous hard disk capacities (often measured in terabytes or trillions of bytes). These servers store MPEG compressed audio and video images and provide service to end-users over high-speed LANs and WANs. Applications that require video servers include entertainment, training/education, and video-enabled databases. WAN Wide Area Network. A communications network that services a geographic area larger than that served by a local area network or metropolitan area network. Whiteboarding A term used to describe the placement of shared documents on an on-screen "shared notebook" or "whiteboard". Multiple users can simultaneously view and annotate a document.
