Chapter 1 | About the XT Series

The Avaya Scopia® XT Series incorporates state-of-the-art video technology for high definition (HD) conferencing.
You can locally host videoconferences with the built-in MCU. The XT Series seamlessly works with a wide variety of
endpoints, including H.323, SIP, Scopia® Desktop Clients, Scopia® Mobile devices, and ISDN endpoints (via
Scopia® 100 Gateway).

You can use the XT Series as an MCU only, or as an endpoint by connecting a monitor, camera, and microphone.
This section provides an overview of the general features and capabilities available in the XT Series:

•

The XT Series is a dedicated videoconferencing endpoint which can also host its own videoconferences with its
built-in MCU, without requiring an external MCU.

•

Excellent video quality, with resolutions of 720p, and up to 1080p at an unprecedented 60 frames per second
(fps), depending on the license.

•

Support for dual HD video streams, allowing PC presentations to be shared alongside video from the camera in
resolutions of up to 1080p at 60fps, depending on the license.

•

Seamlessly share data and presentations with third-party endpoints.

•

DVD-quality audio with up to 48 kHz sampling rate audio encoding capability. The sampling rate is a measure
of the accuracy of the audio when it is digitized. The XT Series endpoints are shipped with different
microphones depending on the model. You can add dedicated Microphone Pods or additional analog
microphones if required.

•

High quality video and audio even with limited bandwidth or poor network conditions, by using two compression
methods:

–

H.264 Scalable Video Coding Technology (SVC) in point-to-point calls. SVC extends the H.264 codec
standard to dramatically increase error resiliency and video quality without the need for higher bandwidth.

–

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.

–

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.

•

Ability to record and playback videoconferences using a USB drive (may require license, depending on the
model).

•

For an even better experience, Scopia® Control enables you to remotely control the XT Series features using
the intuitive touch interface of an Apple® iPad® (may require license, depending on the model).

•

Secure point-to-point video calls and videoconferences, via encrypted connections or using TLS certificates.
You can have up to three remote encrypted participants in a videoconference.

Important:

Using encryption is subject to local regulation. In some countries it is restricted or limited for usage. For more
information, consult your local reseller.

About the XT Series | 5

About the Built-In MCU

You can use your Avaya Scopia® XT Series to join a videoconference hosted on the built-in 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.
Avaya IP Office connects to the XT Series as a SIP server, allowing it to host videoconferences and add

Avaya endpoints to videoconferences.

Important:

If you do not register to IP Office, you cannot host videoconferences on the built-in MCU.

Figure 1: Hosting a videoconference on the XT Series

Your XT Series can host videoconferences on its built-in MCU, with up to nine (one local, eight remote)
participants. If you do not register to IP Office, you cannot host videoconferences on the built-in MCU.

The embedded MCU can mix standard definition and HD endpoints in the same meeting, without one
impacting on the other. The built-in MCU also supports both wide-screen (16:9) and standard formats
(4:3), incorporating them seamlessly into the video layout.

While generating the video layout, the built-in MCU must shrink each participant's image to fit the layout.
So while the composite video layout remains in HD, each participant's image within the layout can reach
a maximum resolution of 448p.

When using the XT Series as an MCU only, not participating locally, we recommend blocking the audio
and video input from this XT Series during the meeting.

Connecting a Computer to the XT Series

About this task

Connect a computer to share a presentation or other content during a call. You connect the video
separately from the audio. The computer video is routed to the DVI port on the XT Codec Unit, while the

audio is routed to the audio-in port.
When you share a computer's sound during a call, remote participants hear the computer's audio output

as well as the audio from the Microphone Pod. However, analog microphones like the one-way
Microphone Pod use the same audio-in port as a connected computer, so to use both at the same

time, connect them via an audio mixer (see Deployment Guide for the Avaya Scopia® XT Series).

Procedure

1. If your computer has a DVI port, connect it to the DVI port on the XT Codec Unit.
Alternatively, use the supplied DVI-VGA adapter to connect a VGA cable from the adapter to
the computer's VGA port.

Tips for Participating in a Videoconference

There are several general recommendations you should follow to optimize your videoconferencing
experience.

We recommend that you read this section before participating in a videoconference for the first time.

•

Use natural gestures and speak normally as in a real meeting.

•

Do not rustle paper or tap on the table or the microphone.

•

Keyboard clicking can be disruptive to the videoconference, so we recommend using the mute
when listening but not actively participating.

•

Zooming too close can show that your eyes are not looking directly at the camera, in some cases.
Set the zoom of the built-in camera so the frame includes the user's head and upper body.

•

If you are using a laptop during a meeting, do not place it too close to the microphone. Noise
produced by the computer fan may interfere with audio quality.

•

Always mute the microphone before moving it.

•

Avoid using your cellular phones during your meeting to avoid electromagnetic interference.

Starting a Meeting

About this task

Like a mobile phone, your Avaya Scopia® XT Series can dial another endpoint by directly entering a new
dial string like a number, or choose a recently dialed entry, or dial a saved contact from your address
book.

If you want to join or host a meeting with several participants, you must decide which MCU is hosting the
meeting. You can host on your own built-in MCU, or on someone else's built-in MCU, or on a
dedicatedMCU like the Scopia® Elite MCU.

To host the meeting on your own built-in MCU, you can either call out to other endpoints to join your
meeting, or you can give out your endpoint's address for them to call in to your endpoint. The endpoint
address you give out can be an IP (like 1.2.3.4), or an H.323 alias (like john_smith) or a URI address
(like [e-mail]). If you invite endpoints outside your network, verify with your system
administrator that your endpoint's address is valid for external endpoints.

Your call is securely encrypted when it shows a padlock icon

Joining a Meeting from the XT Series Calendar

About this task

You can use the calendar of your Avaya Scopia® XT Series endpoint to join a scheduled
videoconference. The calendar for this endpoint is stored in Scopia® Management, hence this
functionality is only available when the XT Series is managed by Scopia® Management.

The calendar displays all Scopia® Management meetings which have invited this XT Series endpoint.
For example, you can book a physical conference room which houses an XT Series room system.

In theXT Series you can only view calendar entries to join meetings. To create or edit a Scopia
Management meeting, you must access the Scopia® Management user portal, or use the 64-bit Scopia
Add-in for Microsoft Outlook.

®

Before you begin

The XT Series must be managed by Scopia® Management (see Deployment Guide for Avaya Scopia
XT Series).

Procedure

1. Access the calendar screen to display today's scheduled meetings. From the XT Series web
interface, select Home and view the Calendar section. From the endpoint's main menu,

Moving the PTZ Camera's Position

About this task

This section details how to set the angle and zoom of a PTZ camera connected to your Avaya Scopia
XT Series.

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.

Once you have set the camera's angle and zoom, the system restores the last camera position the next
time you use the camera. You can store multiple preset camera positions if needed (see Deployment
Guide for Avaya Scopia® XT Series).

®

Procedure

1. Access the camera control settings. From the XT Series web interface, select More Actions
> Cameras Control. From the endpoint's main menu, select Control Camera.

During a meeting, press ok/menu to access the videoconference menu (Figure

Connecting a Computer to the XT Series

About this task

Connect a computer to share a presentation or other content during a call. You connect the video
separately from the audio. The computer video is routed to the DVI port on the XT Codec Unit, while the

audio is routed to the audio-in port.
When you share a computer's sound during a call, remote participants hear the computer's audio output

as well as the audio from the Microphone Pod. However, analog microphones like the one-way
Microphone Pod use the same audio-in port as a connected computer, so to use both at the same

time, connect them via an audio mixer (see Deployment Guide for the Avaya Scopia® XT Series).

Procedure

1. If your computer has a DVI port, connect it to the DVI port on the XT Codec Unit.
Alternatively, use the supplied DVI-VGA adapter to connect a VGA cable from the adapter to
the computer's VGA port.

You can choose one of many video layouts to arrange the display of the presentation, remote video, and
local video.

The XT Series sends both live video and shared content simultaneously on separate channels, known
as dual video. This happens as long as the remote endpoint can receive dual video. If not, it will switch to
sending presentation only until you revert back to live video.

The available bandwidth is shared evenly the two streams by default, but an administrator can
customize this in the XT Series if required.

Your computer content is private, and is only shared with others when you manually choose to do so.

Before you begin

Connect your computer to the XT Series (see Connecting a Computer to the XT Series

on page 8).

Procedure

1.

To share computer content, press Present on the XT Remote Control Unit, from the
endpoint's main menu, or from the in-call menu. From the XT Series web interface, select

Changing Your Own Video Layout

About this task

This section details how to change your own video layout during a call or meeting. 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.

The available layouts depend on the number of streams in your meeting and how many monitors you
have. There are three streams: your own video, the remote video, and a shared presentation. With one
screen, you fill it with the remote video and overlap a small window of your own video. With a shared
presentation, you must choose a video layout. With two monitors, you have more choices of video
layouts (see Figure 37: Examples of video layouts with three streams on single or dual monitors

38).

on page

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Participating in Meetings | 37

Figure 37: Examples of video layouts with three streams on single or dual monitors

As you add more participants to the meeting, each participant adds their own video stream, which
requires an MCU to arrange them into a conference layout. The conference layout is then integrated into
your XT Series as the remote video stream (see Figure 38: Multi-party videoconference places

conference layout as the remote stream on page 38).

Figure 38: Multi-party videoconference places conference layout as the remote stream

The choice of conference layouts offered by the MCU depends on the MCU model. For example, the
layouts in the Scopia® Elite MCU can display up to 28 participants, while the built-in MCU of the XT
Series can display only up to eight remote participants.

Recorded videoconferences use one monitor only. During recording, the auxiliary monitor displays the
same video layout as the primary monitor.

Before a call, your monitor(s) display your own video, except on the Scopia® XT Executive which shows
the computer content by default.

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Changing the Video Layout for all Participants

About this task

As a meeting moderator, you can determine the video layouts for all participants in your meeting. 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.

If you host the meeting on your XT Series built-in MCU, you can change the video layouts on the XT
Series.

The default layout is a dynamic one, which changes form dynamically depending on the number of
participants displaying video. The choice of layouts depends on your XT Series model and the number
of participants with video present in the call.

Setting Recording Preferences

About this task

You can record and playback meetings from a locally connected USB storage device, or record to the
Scopia® Desktop Content Center server. This procedure describes how to configure your USB recording
preferences, such as the video resolution and bitrate. This is useful, for example, to increase the time
available for recording on your USB storage device.

This may require a license, depending on your model. For more information, see Deployment Guide for
Avaya Scopia® XT Series.

You can playback recordings from the local USB storage device either on the XT Series or using any
standard media player. The system saves the file as an MP4, and records the video in H.264 format with
audio in AAC-LC format.

You cannot record locally to USB when encryption is enabled (see Deployment Guide for Avaya
Scopia® XT Series). If you host the meeting on your built-in MCU, you can record either three remote
endpoints if your license is MCU4, or six remote endpoints if your license is MCU9.

Procedure

1. Access the recording settings. From the XT Series web interface, select Basic Settings >
Recording > General. From the endpoint's main menu, select Configure > Recording.

Table 7: Configuring recording settings

Field Description

Enabled (Only in Configure > Advanced > Utilities > Recording) Select Yes to enable recording

and playback from a local USB storage device.

Resolution Select the video resolution of the recording. The frame rate is limited to 25fps. For best

quality, use the default 1080p resolution, but use a lower value if your media player does
not support higher resolutions.

When you change the resolution, the system automatically selects the optimal bitrate for
this resolution.

Bit rate Select the bitrate to determine the file size of the recording. To use less space on your

USB storage device, select a lower bitrate. For the best results, use the default value for
your chosen resolution.

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).

To estimate the space you need for the recording, see Table 8: Typical file sizes based

on the bitrate on page 54. You can see how much recording time is available on your

USB storage device when you access the Recording menu (for details, see Recording

Meetings on page 43).

Audio Alert Select Yes to enable an audio message alert at the beginning of the videoconference,

indicating to all participants that the meeting is being recorded. This alert is also sent to

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.

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Glossary of Terms for Scopia® Solution | 63

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 77.

Cascaded Videoconference

A cascaded videoconference is a meeting distributed over more than one physical Scopia® Elite MCU,
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.

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Glossary of Terms for Scopia® Solution | 64

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 65.

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.

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Glossary of Terms for Scopia® Solution | 65

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 MCU).
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 63.

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 MCU)
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 67.

FPS

See Frames Per Second on page 67.

Frame Rate

See Frames Per Second on page 67.

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

H.225

H.235

H.239

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 is part of the set of H.323 protocols. It defines the messages and procedures used by
gatekeepers to set up calls.

H.235 is the protocol used to authenticate trusted H.323 endpoints and encrypt the media stream during
meetings.

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.

H.245

H.261

H.263

H.264

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 is an older protocol used to compress CIF and QCIF video resolutions. This protocol is not
supported by the XT Series.

H.263 is an older a protocol used to compress video. It is an enhancement to the H.261 protocol.

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 69.

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.

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Glossary of Terms for Scopia® Solution | 69

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 63.

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

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 76.

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

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Glossary of Terms for Scopia® Solution | 71

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 73.

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

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

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Glossary of Terms for Scopia® Solution | 73

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.

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Glossary of Terms for Scopia® Solution | 74

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 66.

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.

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.

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

SD

Service

SIF

Signaling

See Content Slider

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.

Also known as MCU service. See Meeting Type on page 73.

SIF defines a video resolution of 352 x 240 pixels (NTSC) or 352 x 288 (PAL). This is often used in
security cameras.

on page 65.

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.

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Glossary of Terms for Scopia® Solution | 77

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 81.

SIP Registrar

See Registrar

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 65.

SNMP

Simple Network Management Protocol (SNMP) is a protocol used to monitor network devices by
sending messages and alerts to their registered SNMP server.

Software endpoint

on page 76.

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,

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Glossary of Terms for Scopia® Solution | 78

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 78.

Standard Definition

See SD on page 77.

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.

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 MCU only by four times.

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Glossary of Terms for Scopia® Solution | 79

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).

User Guide for Avaya Video Collaboration Solution for IP Office
Version 8.3

Glossary of Terms for Scopia® Solution | 80

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, <endpoint name>@<server_domain_name>. 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

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 82.

VGA

VGA defines a video resolution of 640 x 480 pixels.

Videoconference

on page 81.

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.

User Guide for Avaya Video Collaboration Solution for IP Office

Glossary of Terms for Scopia® Solution | 81

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 76.

Video Switching

See Switched video

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

on page 79.

®

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.
