Chapter 1 | About the Scopia XT Series
Scopia XT Series endpoints incorporate state-of-the-art video technology for high definition (HD) conferencing. All
models of the XT Series include the XT Codec Unit which performs the bulk of the professional videoconferencing,
an elegant remote control which gives intuitive access to its features, and a camera, which varies depending on the
specific model.
This section provides an overview of the general features and capabilities available in the different Scopia XT Series
models (Figure 1: Scopia XT Series products on page 8):
•Ability to host videoconferences locally with a high-capacity embedded MCU, without requiring an external
MCU deployment (selected models only).
•Excellent video quality, with resolutions of up to 1080p at an unprecedented 60 frames per second (fps),
depending on the model.
•Support for dual HD video streams, allowing presentations and video clips to be shared in resolutions of up to
1080p 60 fps, depending on the model.
This includes either video input from two cameras, or one video stream from the camera, and one presentation
stream from the PC.
•Allows to easily share data and presentations with third-party endpoints.
•DVD-quality audio with up to 48 kHz sampling rate audio encoding capability, depending on the model. The
sampling rate is a measure of the accuracy of the audio when it is digitized. As the frequency with which the
audio data is collected, or "sampled", increases, so does the audio quality.
Audio input is provided with either a dedicated 3-way/1-way Microphone Pod, or a microphone embedded in
the camera, depending on the model.
•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 selected models only).
SVC dramatically increases 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.
–H.246 High Profile, which is a video compression standard used for bandwidth efficiency. This allows
quality video at much lower bit rates (selected models only).
•Ability to record videoconferences using a USB drive (may require license, depending on the model).
•For an even better experience, Scopia Control enables you to select and control the camera for the
videoconference, by using the pan, tilt, and zoom features, and place a call 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.

Chapter 2 | Planning the Topology of the
Scopia XT Series Deployment
There are a number of ways that the Scopia XT Series can be deployed in a network, depending on whether you use
it as a room system endpoint or a conference hosting system, and the type of the endpoints connecting to the unit.

Topology for Scopia XT Series as Endpoints
A Scopia XT Series without a built-in MCU is an endpoint and requires an external MCU such as the
Scopia Elite MCU to host videoconferences (Figure 8: Scopia XT Series as Endpoints on page 18):
•The MCU performs media processing for endpoints in all locations, including Scopia XT Series,
Scopia XT Executive and compatible third-party endpoints.
•The MCU can handle multiple videoconferences simultaneously.
•Videoconferences are in high-quality, with maximum resolutions of 1080p and 720p, and include
network error resilience using H.264 Scalable Video Coding (SVC) and high profile H.264 (for
details about these features, see About the Scopia XT Series on page 7).
Scopia XT Executive integrates advanced videoconferencing into a high resolution 24-inch multimedia
LED monitor.

About the Scopia XT Series Embedded MCU
The Scopia XT Series MCU Edition includes an embedded MCU, allowing Scopia XT Series to host
videoconferences locally.
The built-in MCU is available as a license option for the Scopia XT5000, Scopia XT1200, and Scopia XT
Executive models only. Activate the MCU capability by registering the XT Codec Unit, as described in
Registering the Scopia XT Series to Obtain a License Key on page 47.
The following Scopia XT Series MCU Edition options are available, depending on the XT Series model:
•MCU4 - Host videoconferences with up to 4 participants (1 Local and 3 Remote).
•MCU9 - Host videoconferences with up to 9 Participants (1 Local and 8 Remote).
The embedded MCU can host both standard definition (SD) and high definition (HD) endpoints
simultaneously (see Table 5: Video capabilities for participants hosted by Scopia XT Series MCU Edition
on page 19 for details):
•The MCU processes video streams from all endpoints to ensure the video displays correctly for all
possible layouts, regardless of the endpoint resolution or picture format.
•The presence of SD endpoints does not affect the quality received by HD endpoints. SD endpoints
receive SD video streams and HD endpoints receive HD video streams.
•Both wide-screen (16:9) and standard formats (4:3) are incorporated into the continuous presence
(CP) video layout.

Important:
For MCU9, the capabilities depend on the selected CP layout.
For the best experience when using the Scopia XT Series MCU Edition, we recommend:
•Enabling the High Bandwidth Option (12Mbps), available as a separate license (for details, see
Installing and Enabling Licenses which Extend System Functionality on page 48). Otherwise, the
MCU sends out a lower resolution at the standard 6Mbps total bandwidth.
•If the Scopia XT Series is used only as an MCU for hosting videoconferences, block the audio and
video input from this Scopia XT Series during the meeting. For details, see Configuring Call
Settings on page 102.
As you add more XT Series endpoints, you can manage them centrally with Scopia Management. This
would enable centralized updating, backing up and control.
Planning the Topology for the Scopia XT Series with Scopia
XT Desktop
Scopia XT Series SMB Edition enables you to locally host videoconferences using its built-in MCU, and
extends your videoconferences to participants joining from a computer (with Scopia Desktop Client) or a
mobile device (using Scopia Mobile).
For example, when you start a videoconference with the XT Series hosting the call, you can add other
participants by asking them to connect via a web link to the Scopia XT Desktop Server, which would
automatically install and launch Scopia Desktop Client on their computers, or Scopia Mobile on their
mobile devices.
The main features of the Scopia XT Series SMB Edition include:
•Remote users can easily connect to a meeting hosted by the built-in MCU on the XT Series, by
connecting via the Scopia XT Desktop Server.
The deployment has very few components. You do not need additional hardware like an external
MCU, Scopia PathFinder for firewall traversal, or Scopia ECS Gatekeeper for routing calls.
•The included Scopia XT Desktop provides built-in NAT and firewall traversal functionality, enabling
secure remote connections from Scopia Mobile and Scopia Desktop Clients.
You can enable this functionality via the XT Series license.

The Scopia XT Series SMB Edition includes the following options:
•Full SMB4 - Basic MCU level with up to four participants: 1 local and 3 remote mixed endpoints
and PC clients.
•Full SMB9 - Advanced MCU level, with up to 9 participants:
–One local and eight remote endpoints
Or
–One local and seven mixed endpoints and PC clients
Figure 9: Scopia XT Series SMB Edition Deployment on page 20 shows a typical topology for the
Scopia XT Series SMB Edition solution. For more information, see the Solution Guide for Scopia
Solution.

Planning NAT and Firewall Traversal with Scopia XT Series
The Scopia XT Series fully supports NAT and firewall traversal, enabling you to place the unit behind a
NAT router or firewall and connect with other endpoints seamlessly. This section describes the available
methods to incorporate NAT and firewall traversal with XT Series:
•Using a Radvision HTTP server or a STUN public server for NAT and firewall traversal
When the XT Series hosts a videoconference with endpoints outside the enterprise (Figure
10: Using an HTTP/STUN Server for NAT and Firewall Traversal on page 21), it first queries the
