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

You can control the XT Codec Unit using the SCOPIA XT Series API (requires integration with

AMX, Creston, or Extron control devices). Contact RADVISION customer support to receive the

Reference Guide for SCOPIA XT Series API, which includes the list of commands over the

Ethernet interface.

Implementing Port Security for the SCOPIA XT Series

The SCOPIA XT Series provides video technology for room conferencing, including support for

dual stream 1080p video, high quality data sharing, high quality full band audio and a high

capacity embedded MCU.

Ports to Open on the SCOPIA XT Series

The SCOPIA XT Series is typically located in the enterprise network and is connected to the

DMZ. When opening ports to and from the SCOPIA XT Series, use the following as a reference:

•

If you are opening ports that are both to and from the SCOPIA XT Series, see Table 2-2 on

page 16.

•

If you are opening outbound ports from the SCOPIA XT Series, see Table 2-3 on page 18.
