Figure 2: Managing all components of the Scopia® Solution • Endpoint management Remotely configure, upgrade and monitor both Scopia® Solution and third-party endpoints via the administrator portal. Every dedicated endpoint requires a license to join a videoconference and to be defined and managed by Scopia® Management (see Planning Licenses for Integration with Aura Collaboration Suite on page 20). • Resources and bandwidth management Configure your network devices and endpoints for effective bandwidth control. For example, you can determine when meetings are cascaded between multiple MCUs (for more information, see the Administrator Guide for Scopia® Management). You can also monitor in real-time from the administrator portal's dashboard, or generate reports to see network statistics for a given time period. • User management You can manage user access by creating profiles with a set of capabilities. You can also create virtual rooms and assign endpoints. Scopia® Management also integrates with existing directory servers such as Microsoft Active Directory, IBM Lotus Domino for easy user provisioning. • Meeting management Schedule, moderate, and reserve resources for your videoconferences via the user portal. Scopia® Management can also work with Microsoft Outlook or IBM Lotus Notes for an easy and intuitive calendar application scheduling. Using one of the Scopia® Management plug-ins for Microsoft Outlook, you can easily schedule meetings with resources directly from Microsoft Outlook (2010 or later) or a calendar application on your mobile device (see Planning User Access to Videoconferences on page 22). • Interface to unified communication solutions Scopia® Management provides the interface to market leading unified communication solutions such as Avaya Aura Collaboration Suite, Microsoft Lync Server, Microsoft Office Communications Server, and IBM Lotus Sametime.

Chapter 2 | Planning your Avaya Scopia® Management Deployment When planning your Scopia® Management deployment, it is important to understand the minimum system requirements described in this section. You can deploy Scopia® Management differently, depending on the needs of your organization. There are several solutions defined in the Scopia® Solution Guide, each with its own deployment scenario and network topology. Decide on the type of deployment you need based on your video requirements and your existing network topology. The Scopia® Solution Guide details the considerations for choosing each of the deployments, and the locations to place each of the solution components within the network topology. When planning your deployment, it is also important to consider port security (see Implementing Port Security for Avaya Scopia® Management on page 8) and whether to install redundant Scopia® Management servers for high availability (Administrator Guide for Avaya Scopia® Management). For installation procedures for each of the components of the Scopia® Solution, see the product’s Installation Guide.

Planning the Topology of the Avaya Scopia® Management This section describes the guidelines for deploying this and other Scopia® Solution components in your video network when you integrate with Aura Collaboration Suite. You can deploy Scopia® Solution components either in a centralized or distributed solution: • In a centralized topology (Figure 3: Centralized Scopia® Solution deployment with Aura Collaboration Suite on page 18), all the components are installed in the same location.
Figure 3: Centralized Scopia® Solution deployment with Aura Collaboration Suite When deploying the Scopia® Solution for Aura Collaboration Suite, you gain state-of-the-art enterprise videoconferencing using Avaya Scopia® Desktop and Avaya Scopia® Mobile, while enabling these meetings to also include participants on Avaya UC devices such as Flare, One-X, IP Deskphone and ADVD. The solution includes these mandatory components: – Scopia® Elite 6000 for Aura Collaboration Suite, responsible for combining images from different endpoints into a single continuous presence image to enable effective videoconferencing. – Avaya Scopia® Management for Aura Collaboration Suite, which sits at the core of your Scopia® Solution and offers a comprehensive management solution for video communications where enterprises can efficiently control the videoconferencing network. The MCU can only function and connect calls when managed and controlled by Scopia® Management for Aura Collaboration Suite.

– Scopia® Desktop server for Aura Collaboration Suite, the desktop videoconferencing system turning PCs, Macs and mobile devices into videoconferencing endpoints. The Scopia® Desktop server brings together meetings with Scopia® Desktop Clients and Scopia® Mobile devices, passing their media connections to the MCU. A SIP trunk connects the Aura Session Manager to Scopia® Management, while an H.323 trunk connects the Aura Communication Manager also to Scopia® Management. Scopia® Management synchronizes automatically and periodically with the Web License Manager (WebLM) installed on the Aura System Manager to manage the Collaboration Suite licenses. For detailed information on licenses, see Administrator Guide for Avaya Scopia® Management for Aura Collaboration Suite. You can also optionally add Aura Conferencing (AAC) to transmit media to the MCU. • In a distributed topology (Figure 4: Additional components in other locations for a distributed deployment on page 19), you can add components in other locations to create a scalable and geographically distributed solution. You can deploy a full set of videoconferencing components in the headquarters, and distribute additional MCUs and Scopia® Desktop servers over several branches. Each branch can have one or more of these servers depending on the branch's requirements for videoconferencing capacity and high availability. To provide scalability and high availability with service preservation, you can also cluster the Scopia® Desktop servers behind a load balancer. The Scopia® Desktop servers are typically deployed in the DMZ to provide connection to participants from both the internal and external networks.
Figure 4: Additional components in other locations for a distributed deployment For a detailed description of the Scopia® Solution components, refer to Scopia® Solution Guide.

Planning Licenses for Integration with Aura Collaboration Suite As part of integrating Scopia® Solution with Aura Collaboration Suite, you must plan the number of licenses to purchase and allocate. There are four types of licenses: • Scopia® User for Aura Collaboration Suite licenses offer complete functionality for users of Scopia® Desktop, Scopia® Mobile, and other supported UC clients. • Guest user licenses are free, offering limited functionality guest Scopia® Desktop and Scopia® Mobile users. • Scopia® Named Video Endpoint for Aura Collaboration Suite licenses offer complete functionality for dedicated video endpoints like the XT Series. This license, which grants you the right to join videoconferences, is distinct and separate from other product-specific licenses which activate features in the XT Series. • Scopia® Guest Video Endpoint for Aura Collaboration Suite licenses offer limited functionality to guest users on dedicated video endpoints. You purchase a pool of these licenses to allow a limited number of endpoints without a Scopia® Named Endpoint license to join a meeting, usually joining from an external network. When guest endpoints start or join a meeting, they are placed in the waiting room until the moderator joins the meeting. Guest endpoints are not defined or managed in Scopia® Management.

If you have a personal endpoint like a Scopia® XT Executive, a Scopia® Named Endpoint license enables you to participate in meetings from that endpoint only. You cannot join from a computer (Scopia® Desktop) or a mobile device (Scopia® Mobile) unless you also have a Scopia® User license. Typically, you assign each member of your organization a Scopia® User license, and each dedicated endpoint a Scopia® Named Endpoint license (see Table 7: Estimating the number of Scopia® licenses required on page 22).
Table 7: Estimating the number of Scopia® licenses required License
Number of Licenses
Scopia® User licenses
One license per employee
Scopia® Named Endpoint licenses
One license per dedicated endpoint
Scopia® Guest Endpoint licenses
One license per external dedicated endpoint that will join a meeting simultaneously.
You install licenses on the Avaya Web License Manager (WebLM) server, where Scopia® Management retrieves the license information and uses it to manage users and dedicated endpoints (see Administrator Guide for Avaya Scopia® Management). If you have an existing Aura Collaboration Suite and are integrating Scopia® Solution, you can use existing Aura Collaboration Suite licenses as Scopia® User licenses as well.
Planning User Access to Videoconferences As part of deploying Scopia® Solution, you need to plan how users in your organization start videoconferences. Users can either schedule a meeting in advance, and reserve the required video network resources, or they can start an instant meeting. Scheduling meetings with resources ensures a high quality user experience. Otherwise, if there are not enough resources during the videoconference, the system may either downgrade the video quality or block additional participants from joining. Users can schedule meetings with resources in one of two ways: • From Microsoft Outlook (2010 or later), using a Scopia® Management plug-in for Microsoft Outlook. • From the Scopia® Management User Portal. When scheduling from either one of these plug-ins for Microsoft Outlook, Scopia® Management reserves both the endpoint resources and their required MCU connections. Users can start instant meetings in one of two ways: • Dialing an endpoint directly from another endpoint. To dial more than one endpoint, users dial the MCU dial prefix and a virtual room number (personal or public). • Dialing an endpoint from their virtual room in Scopia® Desktop Client, using the MCU dial prefix. You set up the MCU prefix and virtual room numbers according to your organization's dial plan.

Figure 6: Planning User Access to Scheduling Meetings The most common way for users to schedule videoconferences is from Microsoft Outlook, since they are already familiar with its interface and are using it to schedule all other (non-video) meetings. This requires deploying one of the Scopia® Management plug-ins for Microsoft Outlook. Decide which plug-in is right for your organization by using Table 8: Comparing features of the different Microsoft Outlook Plug-ins on page 23 as a guide. For example, if users in your organization have Mac computers or schedule meetings on-the-go from their mobile devices, deploy Scopia® Plug-in for Microsoft Exchange (see Installing the Scopia® Plug-in for Microsoft Exchange on page 24). The Scopia® Add-in for Microsoft Outlook (64-bit), allows more settings to be configured from Outlook, but requires installation on each client (see User Guide for Scopia® Add-in for Microsoft Outlook).

There is an additional plug-in available that does not require a user account in Scopia® Management (see Administrator Guide for Avaya Scopia® Desktop server). Users cannot reserve video network resources with this plug-in.
Installing the Scopia® Plug-in for Microsoft Exchange About this task With the Scopia® Plug-in for Microsoft Exchange, users with a virtual room can easily schedule videoconferences without installing a plugin on their computer or device. Since it works on the Exchange server, users can schedule directly from their Outlook client or other calendar application configured with the Microsoft Exchange server, such as: Microsoft Outlook for Mac, Outlook Web App, and both Windows and iOS-based mobile devices. Install the Scopia® Plug-in for Microsoft Exchange as described below. As part of the installation, you need to define a keyword that users enter when they schedule meetings, to mark the meeting as a videoconference and reserve video network resources. For example, if you defined video as your keyword for the Location field, users must enter video when scheduling videoconferences in Outlook:
Figure 7: Scheduling a videoconference For other scheduling options, see Planning User Access to Videoconferences on page 22. To uninstall the Scopia® Plug-in for Microsoft Exchange, run the uninstall.ps1 file and restart the Microsoft Exchange Transport service.
Important: This procedure is for certified Microsoft Exchange integrators who can access the command shell, are familiar with Exchange's account impersonation and how to restart Exchange's transport service.
Before you begin • The installation of Scopia® Plug-in for Microsoft Exchange typically takes a few minutes and temporarily disconnects the Microsoft Exchange server from the Internet. After the installation, check that both the Microsoft Exchange and the Scopia® Plug-in for Microsoft Exchange is functioning properly by performing tests (for example, send a few test invitations). Consider sending a maintenance notice to all users, alerting them that the Exchange Server is disconnected and cannot send and receive emails during this time. • In Microsoft Active Directory, create a user account (such as scopia_admin) for Exchange impersonation, to allow Scopia® Management to perform scheduling functionality via Microsoft Outlook on behalf of the user by impersonating that login. This account is configured in this procedure to have access to user information and calendars by impersonating users when scheduling meetings and updating calendar information. You need the account username and password to install Scopia® Plug-in for Microsoft Exchange.

For example, when a user (
[email protected]) schedules a videoconference from her mobile device, the message goes through the Scopia® Plug-in for Microsoft Exchange, where the scopia_admin account intercepts and processes the message as a videoconference invitation, and then forwards it to Exchange Web Service as if the sender is
[email protected]. • To schedule videoconferences, each person must have a user account in Scopia® Management (see Administrator Guide for Avaya Scopia® Management). • We recommend creating a Scopia® Management user account specifically for the Scopia® Plug-in for Microsoft Exchange (see Administrator Guide for Avaya Scopia® Management). You use the credentials of this account as part of installing Scopia® Plug-in for Microsoft Exchange. Alternatively, you can use any Scopia® Management user account, such as the administrator's.
Procedure 1. Copy all the setup files for Scopia® Plug-in for Microsoft Exchange to a temporary local folder on the Exchange server (such as c:/temp/scopia_exchange_installation). These files come with Scopia® Management. 2. Configure the following values in the settings.properties file for Scopia® Plug-in for Microsoft Exchange, in the For Administrator area. Whenever you modify these values, restart the Microsoft Exchange Transport service on the Microsoft Exchange server. //For Administrator ScopiaManagement.url=http://111.111.111.111:8080 ScopiaManagement.loginID=admin ScopiaManagement.password=1111

Glossary of Terms for Scopia® Solution 1080p See Full HD on page 43.
2CIF 2CIF describes a video resolution of 704 x 288 pixels (PAL) or 704 x 240 (NTSC). It is double the width of CIF, and is often found in CCTV products.
2SIF 2SIF describes a video resolution of 704 x 240 pixels (NTSC) or 704 x 288 (PAL). This is often adopted in IP security cameras.
4CIF 4CIF describes a video resolution of 704 x 576 pixels (PAL) or 704 x 480 (NTSC). It is four times the resolution of CIF and is most widespread as the standard analog TV resolution.
4SIF 4SIF describes a video resolution of 704 x 480 pixels (NTSC) or 704 x 576 (PAL). This is often adopted in IP security cameras.
720p See HD on page 46.
AAC AAC is an audio codec which compresses sound but with better results than MP3.
Alias An alias in H.323 represents the unique name of an endpoint. Instead of dialing an IP address to reach an endpoint, you can dial an alias, and the gatekeeper resolves it to an IP address.
Installation Guide for Avaya Scopia® Management for Aura Collaboration Suite Version 8.3
Glossary of Terms for Scopia® Solution | 39
AGC (Automatic Gain Control) Automatic Gain Control (AGC) smooths audio signals through normalization, by lowering sounds which are too strong and strengthening sounds which are too weak. This is relevant with microphones situated at some distance from the speaker, like room systems. The result is a more consistent audio signal within the required range of volume.
Auto-Attendant Auto-Attendant, also known as video IVR, offers quick access to meetings hosted on MCUs, via a set of visual menus. Participants can select menu options using standard DTMF tones (numeric keypad). AutoAttendant works with both H.323 and SIP endpoints.
Balanced Microphone A balanced microphone uses a cable that is built to reduce noise and interference even when the cable is long. This reduces audio disruptions resulting from surrounding electromagnetic interference.
BFCP (Binary Floor Control Protocol) BFCP is a protocol which coordinates shared videoconference features in SIP calls, often used by one participant at a time. For example, when sharing content to others in the meeting, one participant is designated as the presenter, and is granted the floor for presenting. All endpoints must be aware that the floor was granted to that participant and react appropriately.
Bitrate Bitrate is the speed of data flow. Higher video resolutions require higher bitrates to ensure the video is constantly updated, thereby maintaining smooth motion. If you lower the bitrate, you lower the quality of the video. In some cases, you can select a lower bitrate without noticing a significant drop in video quality; for example during a presentation or when a lecturer is speaking and there is very little motion. In video recordings, the bitrate determines the file size for each minute of recording. Bitrate is often measured in kilobits per second (kbps).
Call Control See Signaling on page 54.
Cascaded Videoconference A cascaded videoconference is a meeting distributed over more than one physical Scopia® Elite 6000, where a master MCU connects to one or more slave MCUs to create a single videoconference. It increases the meeting capacity by combining the resources of several MCUs. This can be especially useful for distributed deployments across several locations, reducing bandwidth usage.
Installation Guide for Avaya Scopia® Management for Aura Collaboration Suite Version 8.3
Glossary of Terms for Scopia® Solution | 40
CIF CIF, or Common Intermediate Format, describes a video resolution of 352 × 288 pixels (PAL) or 352 x 240 (NTSC). This is sometimes referred to as Standard Definition (SD).
Content Slider The Scopia® Content Slider stores the data already presented in the videoconference and makes it available for participants to view during the meeting.
Continuous Presence Continuous presence enables viewing multiple participants of a videoconference at the same time, including the active speaker. This graphics-intensive work requires scaling and mixing the images together into one of the predefined video layouts. The range of video layouts depends on the type of media processing supported, typically located in the MCU.
Control Control, or media control, sets up and manages the media of a call (its audio, video and data). Control messages include checking compatibility between endpoints, negotiating video and audio codecs, and other parameters like resolution, bitrate and frame rate. Control is communicated via H.245 in H.323 endpoints, or by SDP in SIP endpoints. Control occurs within the framework of an established call, after signaling.
CP See Continuous Presence on page 41.
Dedicated Endpoint A dedicated endpoint is a hardware endpoint for videoconferencing assigned to a single user. It is often referred to as a personal or executive endpoint, and serves as the main means of video communications for this user. For example, Scopia® XT Executive. It is listed in the organization's LDAP directory as associated exclusively with this user.
Dial Plan A dial plan defines a way to route a call and to determine its characteristics. In traditional telephone networks, prefixes often denote geographic locations. In videoconferencing deployments, prefixes are also used to define the type and quality of a call. For example, dial 8 before a number for a lower bandwidth call, or 6 for an audio-only call, or 5 to route the call to a different branch.
Installation Guide for Avaya Scopia® Management for Aura Collaboration Suite Version 8.3
Glossary of Terms for Scopia® Solution | 41
Dial Prefix A dial prefix is a number added at the beginning of a dial string to route it to the correct destination, or to determine the type of call. Dial prefixes are defined in the organization's dial plan. For example, dial 9 for an outside line, or dial 6 for an audio only call.
Distributed Deployment A distributed deployment describes a deployment where the solution components are geographically distributed in more than one network location.
DNS Server A DNS server is responsible for resolving domain names in your network by translating them into IP addresses.
DTMF DTMF, or touch-tone, is the method of dialing on touch-tone phones, where each number is translated and transmitted as an audio tone.
Dual Video Dual video is the transmitting of two video streams during a videoconference, one with the live video while the other is a shared data stream, like a presentation.
Dynamic Video Layout The dynamic video layout is a meeting layout that switches dynamically to include the maximum number of participants it can display on the screen (up to 9 on the XT Series, or up to 28 on Scopia® Elite 6000). The largest image always shows the active speaker.
E.164 E.164 is an address format for dialing an endpoint with a standard telephone numeric keypad, which only has numbers 0 - 9 and the symbols: * and #.
Endpoint An endpoint is a tool through which people can participate in a videoconference. Its display enables you to see and hear others in the meeting, while its microphone and camera enable you to be seen and heard by others. Endpoints include dedicated endpoints, like Scopia® XT Executive, software endpoints

like Scopia® Desktop Client, mobile device endpoints like Scopia® Mobile, room systems like XT Series, and telepresence systems like Scopia® XT Telepresence.
Endpoint Alias See Alias on page 39.
FEC Forward Error Correction (FEC) is a proactive method of sending redundant information in the video stream to preempt quality degradation. FEC identifies the key frames in the video stream that should be protected by FEC. There are several variants of the FEC algorithm. The Reed-Solomon algorithm (FECRS) sends redundant packets per block of information, enabling the sender (like the Scopia® Elite 6000) to manage up to ten percent packet loss in the video stream with minimal impact on the smoothness and quality of the video.
FECC Far End Camera Control (FECC) is a feature of endpoint cameras, where the camera can be controlled remotely by another endpoint in the call.
Forward Error Correction See FEC on page 43.
FPS See Frames Per Second on page 43.
Frame Rate See Frames Per Second on page 43.
Frames Per Second Frames Per Second (fps), also known as the frame rate, is a key measure in video quality, describing the number of image updates per second. The average human eye can register up to 50 frames per second. The higher the frame rate, the smoother the video.
Full HD Full HD, or Full High Definition, also known as 1080p, describes a video resolution of 1920 x 1080 pixels.

Full screen Video Layout The full screen view shows one video image. Typically, it displays the remote presentation, or, if there is no presentation, it displays the other meeting participant(s).
Gatekeeper A gatekeeper routes audio and video H.323 calls by resolving dial strings (H.323 alias or URI) into the IP address of an endpoint, and handles the initial connection of calls. Gatekeepers also implement the dial plan of an organization by routing H.323 calls depending on their dial prefixes. Scopia® Management includes a built-in Avaya Scopia® Gatekeeper, while ECS is a standalone gatekeeper.
Gateway A gateway is a component in a video solution which routes information between two subnets or acts as a translator between different protocols. For example, a gateway can route data between the headquarters and a partner site, or between two protocols like the TIP Gateway, or the Scopia® 100 Gateway.
GLAN GLAN, or gigabit LAN, is the name of the network port on the XT Series. It is used on the XT Series to identify a 10/100/1000MBit ethernet port.
H.225 H.225 is part of the set of H.323 protocols. It defines the messages and procedures used by gatekeepers to set up calls.
H.235 H.235 is the protocol used to authenticate trusted H.323 endpoints and encrypt the media stream during meetings.
H.239 H.239 is a widespread protocol used with H.323 endpoints, to define the additional media channel for data sharing (like presentations) alongside the videoconference, and ensures only one presenter at a time.
H.243 H.243 is the protocol used with H.323 endpoints enabling them to remotely manage a videoconference.
Installation Guide for Avaya Scopia® Management for Aura Collaboration Suite Version 8.3
Glossary of Terms for Scopia® Solution | 44
H.245 H.245 is the protocol used to negotiate call parameters between endpoints, and can control a remote endpoint from your local endpoint. It is part of the H.323 set of protocols.
H.261 H.261 is an older protocol used to compress CIF and QCIF video resolutions. This protocol is not supported by the XT Series.
H.263 H.263 is an older a protocol used to compress video. It is an enhancement to the H.261 protocol.
H.264 H.264 is a widespread protocol used with SIP and H.323 endpoints, which defines video compression. Compression algorithms include 4x4 transforms and a basic motion comparison algorithm called Pslices. There are several profiles within H.264. The default profile is the H.264 Baseline Profile, but H.264 High Profile uses more sophisticated compression techniques.
H.264 Baseline Profile See H.264 on page 45.
H.264 High Profile H.264 High Profile is a standard for compressing video by up to 25% over the H.264 Baseline Profile, enabling high definition calls to be held over lower call speeds. It requires both sides of the transmission (sending and receiving endpoints) to support this protocol. H.264 High Profile uses compression algorithms like: • CABAC compression (Context-Based Adaptive Binary Arithmetic Coding) • 8x8 transforms which more effectively compress images containing areas of high correlation These compression algorithms demand higher computation requirements, which are offered with the dedicated hardware available in Scopia® Solution components. Using H.264 High Profile in videoconferencing requires that both the sender and receiver's endpoints support it. This is different from SVC which is an adaptive technology working to improve quality even when only one side supports the standard.
H.320 H.320 is a protocol for defining videoconferencing over ISDN networks.
Installation Guide for Avaya Scopia® Management for Aura Collaboration Suite Version 8.3
Glossary of Terms for Scopia® Solution | 45
H.323 H.323 is a widespread set of protocols governing the communication between endpoints in videoconferences and point-to-point calls. It defines the call signaling, control, media flow, and bandwidth regulation.
H.323 Alias See Alias on page 39.
H.350 H.350 is the protocol used to enhance LDAP user databases to add video endpoint information for users and groups.
H.460 H.460 enhances the standard H.323 protocol to manage firewall/NAT traversal, employing ITU-T standards. Endpoints which are already H.460 compliant can communicate directly with the PathFinder server, where the endpoint acts as an H.460 client to the PathFinder server which acts as an H.460 server.
HD A HD ready device describes its high definition resolution capabilities of 720p, a video resolution of 1280 x 720 pixels.
High Availability High availability is a state where you ensure better service and less downtime by deploying additional servers. There are several strategies for achieving high availability, including deployment of redundant servers managed by load balancing systems.
High Definition See HD on page 46.

HTTPS HTTPS is the secured version of the standard web browser protocol HTTP. It secures communication between a web browser and a web server through authentication of the web site and encrypting communication between them. For example, you can use HTTPS to secure web browser access to the web interface of many Scopia® Solution products.
Image Resolution See Resolution on page 52.
kbps Kilobits per second (kbps) is the standard unit to measure bitrate, measuring the throughput of data communication between two devices. Since this counts the number of individual bits (ones or zeros), you must divide by eight to calculate the number of kilobytes per second (KBps).
KBps Kilobytes per second (KBps) measures the bitrate in kilobytes per second, not kilobits, by dividing the number of kilobits by eight. Bitrate is normally quoted as kilobits per second (kbps) and then converted to kilobytes per second (KBps). Bitrate measures the throughput of data communication between two devices.
LDAP LDAP is a widespread standard database format which stores network users. The format is hierarchical, where nodes are often represented as branch location > department > sub-department, or executives > managers > staff members. The database standard is employed by most user directories including Microsoft Active Directory, IBM Sametime and others. H.350 is an extension to the LDAP standard for the videoconferencing industry.
Lecture Mode Scopia® Desktop's lecture mode allows the participant defined as the lecturer to see all the participants, while they see only the lecturer. All participants are muted except the lecturer, unless a participant asks permission to speak and is unmuted by the lecturer. This mode is tailored for distance learning, but you can also use it for other purposes like when an executive addresses employees during company-wide gatherings.
Load balancer A load balancer groups together a set (or cluster) of servers to give them a single IP address, known as a virtual IP address. It distributes client service requests amongst a group of servers. It distributes loads
Installation Guide for Avaya Scopia® Management for Aura Collaboration Suite Version 8.3
Glossary of Terms for Scopia® Solution | 47
according to different criteria such as bandwidth, CPU usage, or cyclic (round robin). Load balancers are also known as application delivery controllers (ADC).
Location A location is a physical space (building) or a network (subnet) where video devices can share a single set of addresses. A distributed deployment places these components in different locations, often connected via a VPN.
Management Management refers to the administration messages sent between components of the Scopia® Solution as they manage and synchronize data between them. Management also includes front-end browser interfaces configuring server settings on the server. Management messages are usually transmitted via protocols like HTTP, SNMP, FTP or XML. For example, Scopia® Management uses management messages to monitor the activities of an MCU, or when it authorizes the MCU to allow a call to proceed.
MBps Megabytes per second (MBps) is a unit of measure for the bitrate. The bitrate is normally quoted as kilobits per second (kbps) and then converted by dividing it by eight to reach the number of kilobytes per second (KBps) and then by a further 1000 to calculate the MBps.
MCU An MCU, or Multipoint Control Unit, connects several endpoints to a single videoconference. It manages the audio mixing and creates the video layouts, adjusting the output to suit each endpoint's capabilities.
MCU service See Meeting Type on page 49.
Media Media refers to the live audio, video and shared data streams sent during a call. Presentation and Far end camera control (FECC) are examples of information carried on the data stream. Media is transmitted via the RTP and RTCP protocols in both SIP and H.323 calls. The parallel data stream of both live video and presentation, is known as dual video.
Media Control See Control on page 41.

Glossary of Terms for Scopia® Solution | 48
Meeting Type Meeting types (also known as MCU services) are meeting templates which determine the core characteristics of a meeting. For example, they determine if the meeting is audio only or audio and video, they determine the default video layout, the type of encryption, PIN protection and many other features. You can invoke a meeting type by dialing its prefix in front of the meeting ID. Meeting types are created and stored in the MCU, with additional properties in Scopia® Management.
Moderator A moderator has special rights in a videoconference, including blocking the sound and video of other participants, inviting new participants, disconnecting others, determining video layouts, and closing meetings. In Scopia® Desktop Client, an owner of a virtual room is the moderator when the room is protected by a PIN. Without this protection, any participant can assume moderator rights.
MTU The MTU, or Maximum Transmission Unit, is the maximum size of data packets sent around your network. This value must remain consistent for all network components, including servers like the MCU and Scopia® Desktop server, endpoints like XT Series and other network devices like LDAP servers and network routers.
Multicast Streaming Multicast streaming sends a videoconference to multiple viewers across a range of addresses, reducing network traffic significantly. Scopia® Desktop server multicasts to a single IP address, and streaming clients must tune in to this IP address to view the meeting. Multicasts require that routers, switches and other equipment know how to forward multicast traffic.
Multi-Point A multi-point conference has more than two participants.
Multi-tenant Service provider, or multi-tenant, deployments enable one installation to manage multiple organizations. All the organizations can reside as tenants within a single service provider deployment. For example, Scopia® Management can manage a separate set of users for each organization, separate local administrators, separate bandwidth policies etc. all within a single multi-tenant installation.
NAT A NAT, or Network Address Translation device, translates external IP addresses to internal addresses housed in a private network. This enables a collection of devices like endpoints in a private network, each with their own internal IP address, can be represented publicly by a single, unique IP address. The
Installation Guide for Avaya Scopia® Management for Aura Collaboration Suite Version 8.3
Glossary of Terms for Scopia® Solution | 49
NAT translates between public and private addresses, enabling users toplace calls between public network users and private network users.
NetSense NetSense is a proprietary Scopia® Solution technology which optimizes the video quality according to the available bandwidth to minimize packet loss. As the available bandwidth of a connection varies depending on data traffic, NetSense's sophisticated algorithm dynamically scans the video stream, and then reduces or improves the video resolution to maximize quality with the available bandwidth.
Packet Loss Packet loss occurs when some of the data transmitted from one endpoint is not received by the other endpoint. This can be caused by narrow bandwidth connections or unreliable signal reception on wireless networks.
PaP Video Layout The PaP (Picture and Picture) view shows up to three images of the same size.
Phantom Power Microphones which use phantom power draw their electrical power from the same cable as the audio signal. For example, if your microphone is powered by a single cable, it serves both to power the microphone and transmit the audio data. Microphones which have two cables, one for sound and a separate power cable, do not use phantom power.
PiP Video Layout The PiP (Picture In Picture) view shows a video image in the main screen, with an additional smaller image overlapping in the corner. Typically, a remote presentation is displayed in the main part of the screen, and the remote video is in the small image. If the remote endpoint does not show any content, the display shows the remote video in the main part of the screen, and the local presentation in the small image.
Point-to-Point Point-to-point is a feature where only two endpoints communicate with each other without using MCU resources.
Installation Guide for Avaya Scopia® Management for Aura Collaboration Suite Version 8.3
Glossary of Terms for Scopia® Solution | 50
PoP Video Layout The PoP (Picture out Picture) view shows up to three images of different size, presented side by side, where the image on the left is larger than the two smaller images on the right.
Prefix See Dial Prefix on page 42.
PTZ Camera A PTZ camera can pan to swivel horizontally, tilt to move vertically, and optically zoom to devote all the camera's pixels to one area of the image. For example, the XT Standard Camera is a PTZ camera with its own power supply and remote control, and uses powerful lenses to achieve superb visual quality. In contrast, fixed cameras like webcams only offer digital PTZ, where the zoom crops the camera image, displaying only a portion of the original, resulting in fewer pixels of the zoomed image, which effectively lowers the resolution. Fixed cameras also offer digital pan and tilt only after zooming, where you can pan up to the width or length of the original camera image.
Q.931 Q.931 is a telephony protocol used to start and end the connection in H.323 calls.
QCIF QCIF, or Quarter CIF, defines a video resolution of 176 × 144 pixels (PAL) or 176 x 120 (NTSC). It is often used in older mobile handsets (3G-324M) limited by screen resolution and processing power.
Quality of Service (QoS) Quality of Service (QoS) determines the priorities of different types of network traffic (audio, video and control/signaling), so in poor network conditions, prioritized traffic is still fully transmitted.
Recordings A recording of a videoconference can be played back at any time. Recordings include audio, video and shared data (if presented). In Scopia® Desktop, any participant with moderator rights can record a meeting. Users can access Scopia® Desktop recordings from the Scopia® Desktop web portal or using a web link to the recording on the portal.

Redundancy Redundancy is a way to deploy a network component, in which you deploy extra units as 'spares', to be used as backups in case one of the components fails.
Registrar A SIP Registrar manages the SIP domain by requiring that all SIP devices register their IP addresses with it. For example, once a SIP endpoint registers its IP address with the Registrar, it can place or receive calls with other registered endpoints.
Resolution Resolution, or image/video resolution, is the number of pixels which make up an image frame in the video, measured as the number of horizontal pixels x the number of vertical pixels. Increasing resolution improves video quality but typically requires higher bandwidth and more computing power. Techniques like SVC, H.264 High Profile and FEC reduce bandwidth usage by compressing the data to a smaller footprint and compensating for packet loss.
Restricted Mode Restricted mode is used for ISDN endpoints only, when the PBX and line uses a restricted form of communication, reserving the top 8k of each packet for control data only. If enabled, the bandwidth values on these lines are in multiples of 56kbps, instead of multiples of 64kbps.
Room System A room system is a hardware videoconferencing endpoint installed in a physical conference room. Essential features include its camera's ability to PTZ (pan, tilt, zoom) to allow maximum flexibility of camera angles enabling participants to see all those in the meeting room or just one part of the room.
RTP RTP or Real-time Transport Protocol is a network protocol which supports video and voice transmission over IP. It underpins most videoconferencing protocols today, including H.323, SIP and the streaming control protocol known as RTSP. The secured version of RTP is SRTP.
RTCP Real-time Control Transport Protocol, used alongside RTP for sending statistical information about the media sent over RTP.
Installation Guide for Avaya Scopia® Management for Aura Collaboration Suite Version 8.3
Glossary of Terms for Scopia® Solution | 52
RTSP RTSP or Real-Time Streaming Protocol controls the delivery of streamed live or playback video over IP, with functions like pause, fast forward and reverse. While the media itself is sent via RTP, these control functions are managed by RTSP
Sampling Rate The sampling rate is a measure of the accuracy of the audio when it is digitized. To convert analog audio to digital, it must collect or sample the audio at specific intervals. As the rate of sampling increases, it raises audio quality.
SBC A Session Border Controller (SBC) is a relay device between two different networks. It can be used in firewall/NAT traversal, protocol translations and load balancing.
Scalability Scalability describes the ability to increase the capacity of a network device by adding another identical device (one or more) to your existing deployment. In contrast, a non-scalable solution would require replacing existing components to increase capacity.
Scopia® Content Slider See Content Slider on page 41.
SD Standard Definition (SD), is a term used to refer to video resolutions which are lower than HD. There is no consensus defining one video resolution for SD.
Service Also known as MCU service. See Meeting Type on page 49.
SIF SIF defines a video resolution of 352 x 240 pixels (NTSC) or 352 x 288 (PAL). This is often used in security cameras.
Installation Guide for Avaya Scopia® Management for Aura Collaboration Suite Version 8.3
Glossary of Terms for Scopia® Solution | 53
Signaling Signaling, also known as call control, sets up, manages and ends a connection or call. These messages include the authorization to make the call, checking bandwidth, resolving endpoint addresses, and routing the call through different servers. Signaling is transmitted via the H.225.0/Q.931 and H.225.0/RAS protocols in H.323 calls, or by the SIP headers in SIP calls. Signaling occurs before the control aspect of call setup.
SIP Session Initiation Protocol (SIP) is a signaling protocol for starting, managing and ending voice and video sessions over TCP, TLS or UDP. Videoconferencing endpoints typically are compatible with SIP or H.323, and in some cases (like Avaya Scopia® XT Series), an endpoint can be compatible with both protocols. As a protocol, it uses fewer resources than H.323.
SIP Server A SIP server is a network device communicating via the SIP protocol.
SIP URI See URI on page 57.
SIP Registrar See Registrar on page 52.
Single Sign On Single Sign On (SSO) automatically uses your network login and password to access different enterprise systems. Using SSO, you do not need to separately login to each system or service in your organization.
Slider See Content Slider on page 41.
SNMP Simple Network Management Protocol (SNMP) is a protocol used to monitor network devices by sending messages and alerts to their registered SNMP server.
Installation Guide for Avaya Scopia® Management for Aura Collaboration Suite Version 8.3
Glossary of Terms for Scopia® Solution | 54
Software endpoint A software endpoint turns a computer or portable device into a videoconferencing endpoint via a software application only. It uses the system's camera and microphone to send image and sound to the other participants, and displays their images on the screen. For example, Scopia® Desktop Client or Scopia® Mobile.
SRTP Secure Real-time Transport Protocol (SRTP) adds security to the standard RTP protocol, which is used to send media (video and audio) between devices in SIP calls. It offers security with encryption, authentication and message integrity. The encryption uses a symmetric key generated at the start of the call, and being symmetric, the same key locks and unlocks the data. So to secure transmission of the symmetric key, it is sent safely during call setup using TLS.
SSO See Single Sign On on page 54.
Standard Definition See SD on page 53.
STUN A STUN server enables you to directly dial an endpoint behind a NAT or firewall by giving that computer’s public internet address.
SVC SVC extends the H.264 codec standard to dramatically increase error resiliency and video quality without the need for higher bandwidth. It is especially effective over networks with high packet loss (like wireless networks) which deliver low quality video. It splits the video stream into layers, comprising a small base layer and then additional layers on top which enhance resolution, frame rate and quality. Each additional layer is only transmitted when bandwidth permits. This allows for a steady video transmission when available bandwidth varies, providing better quality when the bandwidth is high, and adequate quality when available bandwidth is poor.
SVGA SVGA defines a video resolution of 800 x 600 pixels.
Installation Guide for Avaya Scopia® Management for Aura Collaboration Suite Version 8.3
Glossary of Terms for Scopia® Solution | 55
SQCIF SQCIF defines a video resolution of 128 x 96 pixels.
Switched video Switching is the process of redirecting video as-is without transcoding, so you see only one endpoint's image at a time, usually the active speaker, without any video layouts or continuous presence (CP). Using video switching increases the port capacity of the Scopia® Elite 6000 only by four times.
Important: Use switched video only when all endpoints participating in the videoconference support the same resolution. If a network experiences high packet loss, switched video might not be displayed properly for all endpoints in the videoconference.
SXGA SXGA defines a video resolution of 1280 x 1024 pixels.
Telepresence A telepresence system combines two or more endpoints together to create a wider image, simulating the experience of participants being present in the same room. Telepresence systems always designate one of the endpoints as the primary monitor/camera/codec unit, while the remainder are defined as auxiliary or secondary endpoints. This ensures that you can issue commands via a remote control to a single codec base which leads and controls the others to work together as a single telepresence endpoint.
Telepresence - Dual row telepresence room Dual row telepresence rooms are large telepresence rooms with two rows of tables that can host up to 18 participants.
TLS TLS enables network devices to communicate securely using certificates, to provide authentication of the devices and encryption of the communication between them.
Transcoding Transcoding is the process of converting video into different sizes, resolutions or formats. This enables multiple video streams to be combined into one view, enabling continuous presence, as in a typical videoconferencing window.

UC (Unified Communications) UC, or unified communications deployments offer solutions covering a wide range of communication channels. These include audio (voice), video, text (IM or chat), data sharing (presentations), whiteboard sharing (interactive annotations on shared data).
Unbalanced Microphone An unbalanced microphone uses a cable that is not especially built to reduce interference when the cable is long. As a result, these unbalanced line devices must have shorter cables to avoid audio disruptions.
Unicast Streaming Unicast streaming sends a separate stream of a videoconference to each viewer. This is the default method of streaming in Scopia® Desktop server. To save bandwidth, consider multicast streaming.
URI URI is an address format used to locate a device on a network, where the address consists of the endpoint's name or number, followed by the domain name of the server to which the endpoint is registered. For example, @. When dialing URI between organizations, the server might often be the Avaya Scopia® PathFinder server of the organization.
URI Dialing Accessing a device via its URI on page 57.
User profile A user profile is a set of capabilities or parameter values which can be assigned to a user. This includes available meeting types (services), access to Scopia® Desktop and Scopia® Mobile functionality, and allowed bandwidth for calls.
VFU See Video Fast Update (VFU) on page 58.
VGA VGA defines a video resolution of 640 x 480 pixels.

Glossary of Terms for Scopia® Solution | 57
Videoconference A videoconference is a meeting of more than two participants with audio and video using endpoints. Professional videoconferencing systems can handle many participants in single meetings, and multiple simultaneous meetings, with a wide interoperability score to enable a wide variety of endpoints to join the same videoconference. Typically you can also share PC content, like presentations, to other participants.
Video Fast Update (VFU) Video Fast Update (VFU) is a request for a refreshed video frame, sent when the received video is corrupted by packet loss. In response to a VFU request, the broadcasting endpoint sends a new intraframe to serve as the baseline for the ongoing video stream.
Video Layout A video layout is the arrangement of participant images as they appear on the monitor in a videoconference. If the meeting includes a presentation, a layout can also refer to the arrangement of the presentation image together with the meeting participants.
Video Resolution See Resolution on page 52.
Video Switching See Switched video on page 56.
Virtual Room A virtual room in Scopia® Desktop and Scopia® Mobile offers a virtual meeting place for instant or scheduled videoconferences. An administrator can assign a virtual room to each member of the organization. Users can send invitations to each other via a web link which brings you directly into their virtual room. Virtual meeting rooms are also dialed like phone extension numbers, where a user’s virtual room number is often based on that person’s phone extension number. You can personalize your virtual room with PIN numbers, custom welcome slides and so on. External participants can download Scopia® Desktop or Scopia® Mobile free to access a registered user's virtual room and participate in a videoconference.
VISCA Cable A crossed VISCA cable connects two PTZ cameras to enable you to use the same remote control on both.

Waiting Room A waiting room is a holding place for participants waiting for the host or moderator to join the meeting. While waiting, participants see a static image with the name of the owner's virtual room, with an optional audio message periodically saying the meeting will start when the host arrives.
WUXGA WUXGA defines a video resolution of 1920 x 1200 pixels.
XGA XGA defines a Video resolution of 1024 x 768 pixels.
Zone Gatekeepers like Avaya Scopia® ECS Gatekeeper split endpoints into zones, where a group of endpoints in a zone are registered to a gatekeeper. Often a zone is assigned a dial prefix, and usually corresponds to a physical location like an organization's department or branch.
