RADVISION | Administrator Guide for SCOPIA XT1000 Version 2.0

Embedded MCUs and SCOPIA XT Desktop

Built on the SCOPIA XT1000 HD room system with its high capacity embedded MCU, the SCOPIA XT 

Desktop solution combines HD room system capabilities, embedded multi-party conferencing, 

desktop conferencing and firewall traversal. The SCOPIA XT Desktop option is delivered on a CD 

for installation on a separate server.

The solution enables remote users to easily connect to a meeting, relying only on the SCOPIA 

XT1000 and its embedded MCU with no extra hardware to acquire, deploy and configure. A single 

SCOPIA XT Desktop Server is deployed with a single XT1000 endpoint, utilizing the endpoint’s 

embedded MCU. The Desktop Server will connect to one specific XT1000 endpoint and will be tied 

to its hardware address. 

The typical use case would be: a meeting is scheduled in a conference room with SCOPIA XT1000 

and another site. A remote sales person wants to participate to the meeting. The remote user 

opens his/her web browser, points it to SCOPIA XT1000 and connects to the meeting.

Firewall/NAT Support

SCOPIA XT1000 fully supports firewall and NAT traversal using one of these methods:

•

Local Configuration of Firewall/NAT public address. When the system is installed in a NAT 

environment, you can configure the NAT public IP address in the Codec Unit in several ways: 

Manual setting, Automatic Discovery using HTTP, or Automatic Discovery using STUN. Once 

configured, this Firewall/NAT public IP address is then used for all signalling configurations. 

This approach works well in simple Firewall/NAT deployments, typically used by home or 

small business routers, but requires further support to open ports on the Firewall/NAT server. 

Consult your network administrator.

•

H.460. H.460 is a H.323 extension to support firewall and NAT traversal. It is more robust than 

the auto discovery approach and will traverse more complex network configurations. This 

approach requires a Traversal Server, such as RADVISION Pathfinder, to be installed in the 

network. 

Third-party ITU compliant servers are also supported. 

The Codec Unit does not implement a built-in H.460 server. A separate server is required as 

the Codec Unit supports only the client side of H.460.

A further solution for firewall issues can be implemented using the LAN 10/100 port option. When 

enabling the LAN port, the user will be allowed to connect the two adapters to different IP 

networks: for example, LAN connected to the public network and GLAN to a private network.

Note:

When SCOPIA XT1000 is deployed in managed complex network scenarios and is registered to a 

gatekeeper, the gatekeeper management policies will apply to both interfaces. Consult your 

network administrator for any routing problem that may arise.
