Figure 1-1
SCOPIA XT5000 Series as Endpoints
Using the SCOPIA XT Series Embedded MCU
This feature is planned for the future version of this product.
The embedded MCU capability is available in selected models only.
The MCU capability is embedded in the SCOPIA XT Series MCU Edition and can be activated by
registering the XT Codec Unit serial number and the MCU product key in the SCOPIA XT Series
web registration page reserved to SCOPIA XT Series MCU Edition purchasers. Refer to this
address: http://www.radvision.com/XT5000.
The SCOPIA XT Series MCU Edition has the capability of deploying two levels of MCUs:
• MCU4 - Basic MCU level with up to 4 participants (1 Local and 3 Remote). Each participant
receives up to 720p and can send up to 448p.
• MCU9 - Advanced MCU9 level with up to 9 Participants (1 Local and 8 Remote). Each
participant receives up to 720p and can send up to 488p depending on the selected CP
layout. Only the Active Speaker can send up to 448p.
We recommend enabling the High Bandwidth Option (12Mbps) when using the embedded MCU.
If the High Bandwidth option is not enabled, the MCU sends out a lower resolution according
to the standard 4Mbps total bandwidth.
The embedded MCU can host standard definition (SD) and high definition (HD) endpoints
simultaneously. The presence of SD endpoints does not affect the quality received by HD
endpoints. SD endpoints will receive SD video streams and HD endpoints will receive HD video
streams. In the same way 4:3 and 16:9 video formats are included in the best possible way
into the CP mosaic.
In cases when the SCOPIA XT Series is used only as an MCU for hosting videoconferences, we
recommend that you disable the audio and video input from this SCOPIA XT Series. Refer to
the Installation Guide for SCOPIA XT Series for operational information.

Planning NAT and Firewall Traversal with SCOPIA XT Series
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 four approaches to 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
1-2 on page 5), it first queries the HTTP or STUN server to discover its public IP
address, then sends it to any external endpoints wishing to join the conference. The
external endpoints then answer the call using the IP address provided. Configure the XT
Codec Unit for HTTP or STUN autodiscovery.
Figure 1-2
Using an HTTP/STUN Server for NAT and Firewall Traversal
This approach works well in simple NAT and firewall traversal deployments, typically used
by home offices and Small Medium Businesses (SMBs).
• Using a NAT/firewall traversal server supporting H.460
The endpoints in the private network communicate with the endpoints located in the
public network via an H.460 NAT/firewall traversal server, like the SCOPIA PathFinder (see
Figure 1-3 on page 6). Endpoints in the public network can join a conference hosted in
the private network via the traversal server if there is an open connection through the
firewall. Verify the duration of the firewall pinhole and configure that time in the XT
Codec Unit.
RADVISION | Administrator Guide for SCOPIA XT5000 Series Version 3.0
Planning the Topology of the SCOPIA XT Series Deployment | 5
Having a dedicated NAT/firewall traversal server like the SCOPIA PathFinder offers
external endpoints a static address when joining conferences hosted in your organization.
You can dial [email protected] to access from outside the firewall, or you
can dial 1234 directly if you are a H.460 client logged in to the SCOPIA PathFinder Server.
H.460 is an extension of the H.323 protocol used for NAT and firewall traversal, employing
ITU-T standards. The traversal server can be a a SCOPIA PathFinder or a third-party ITU-T
compliant server.
Figure 1-3
Using a NAT and Firewall Traversal Server
Configure the traversal server as the XT Codec Unit gatekeeper and enable the H.460
option. Configure the XT Codec Unit to the IP address of the traversal server SCOPIA
PathFinder.
• Using the XT Series for NAT and firewall traversal
In cases where your organization has no sophisticated firewall protection, the XT Series
can straddle the two network zones using the two network ports provided on the XT Codec
Unit (see Figure 1-4 on page 7).
Use the GLAN ports of the XT Codec Unit simultaneously and connect one port to the
public network and the other to your private network. All communication passes through
the XT Series which acts as the virtual conference room for all the endpoints.
RADVISION | Administrator Guide for SCOPIA XT5000 Series Version 3.0
Planning the Topology of the SCOPIA XT Series Deployment | 6
Figure 1-4
Using XT Series for NAT and Firewall Traversal
There are two possible setups in the GLAN1 and GLAN2 configuration (see Figure 1-4 on
page 7):
1. When there is no gatekeeper, XT Series communicates simultaneously with the public
and private network endpoints using IP addresses. This configuration is suitable for
SMBs.
2. When there is a gatekeeper, it is configured to manage the private network endpoints.
SCOPIA XT Series is registered with the gatekeeper and communicates with endpoints
in the private and in the public network:
–
SCOPIA XT Series communicates with the private network endpoints using IP
addresses or aliases, under the control of the gatekeeper.
–
SCOPIA XT Series communicates with the public network endpoints using IP
addresses.
–
SCOPIA XT Series communicates at the same time both with the public and private
endpoints if the MCU option is activated. In this scenario SCOPIA XT Series uses
either aliases or IP addresses depending on whether it deploys the gatekeeper or
not.
RADVISION | Administrator Guide for SCOPIA XT5000 Series Version 3.0
Planning the Topology of the SCOPIA XT Series Deployment | 7
Supporting ISDN Connectivity
The SCOPIA XT Series supports ISDN connectivity, allowing calls from endpoints to be routed to
the relevant conference using the SCOPIA BRI (Basic Rate Interface) and PRI (Primary Rate
Interface) gateways.
RADVISION has implemented a special pairing mechanism between the gateway and the
endpoint so that ISDN dialing is very simple. After pairing the systems, the participants place
ISDN calls by dialing the remote party ISDN number. The system automatically and
transparently takes care of setting the bit rate and call routing through the ISDN gateway.
A single gateway can serve multiple endpoints. For example, an organization needs to enable
5 endpoints with ISDN connectivity. Assuming the requested ISDN connectivity speed is
256bps, use only one ISDN PRI gateway as it can support 5 concurrent calls of 256bps each.
With the gateway approach less communication lines are needed. As all gateways do not
connect at the same time and not all calls are ISDN, many more endpoints can share the same
ISDN connection and gateway.
Implementing External API Control
The SCOPIA XT Series has a feature-rich API. Using this API, integrators can implement AMX
and Creston applications to control the XT Codec Unit. The API is implemented as commands
over the Ethernet interface. Contact RADVISION customer support for a copy of the API
documentation.

How to Update the Software for SCOPIA XT Series
This section describes how to upgrade the software running on the XT Codec Unit.
Note
Any software version, even if it is restricted by a license, can run in a temporary mode for
practically 24 hours. After that period of time, you must enter a new license key or download
the previous allowed version.
The software version 3.0 does not need a license.
Download a new software package from the RADVISION web or FTP site. The software release
contains new features or patch release.
The software update package is an auto-extracting file containing a software version, usually
with a filename indicating the exact version number (for example: XT5000_V3_0_115.exe).
For further information, see http://licensing.radvision.com/.
You can update the software version either running the update package from a PC or from the
USB key that is shipped together with the product. When considering the update method,
remember that by downloading the update package from the RADVISION web or FTP site you
get the latest available version.
You can update the software running on a XT Codec Unit in two different modes, by means of
the same software package.
• In standard mode the XT Codec Unit is upgraded while operating in a regular way. The
standard system menus are visible. All the configuration settings and user data are
preserved in the update process.

Solution
Make sure the network connection to the remote endpoint has enough bandwidth. Low
bandwidth conditions results in a reduction of resolution at the XT Codec Unit.
Solution
Make sure the VISCA cable is connected to the VISCA IN port of the camera. The VISCA cable
is part of the cable harness that connects the camera to the XT Codec Unit and is used to
control the camera. A common mistake is to connect this cable to VISCA OUT instead of VISCA
IN. This prevents the XT Codec Unit from setting the camera to the necessary resolution.
