Video conference platforms, gateways, MCUs and bridges frequently need ISDN access and this is normally provided via dedicated ISDN services, even though the video conferencing may only be used periodically. Some examples of how to connect video to ISDN are show below.

Liberator can be used to source network access for video or connect VC by using existing ISDN.

Liberator can also be used to serve several videoconferencing devices through a single PRI access and provides local inter-connectivity without having to make a network call. Both BRI"S" and "U" interfaces can be supported on the DUO. This may be particularly relevant when having to drive over long distances.

If the video device, such as an MCU needs PRI but this is not available from the carrier, or where BRI ownership is less than PRI, Liberator can build multiple BRIs into a local PRI.

This is explained in more detail in the BRI to PRI page.

Links to Products for this application:

Liberator "S"

• Supports up to 3 PRIs
• BRI "S" interfaces (4, 8, 12 or 16 ports) connect to both network and local devices
• Connects local devices without a network call
• Easy to manage and reconfigure via intuitive graphical interface (click for brief presentation)

Liberator "DUO"

• Easy to manage and reconfigure via intuitive graphical interface
• Supports up to 4 PRIs
• BRI "S" or "U" interfaces (4, 8, 12 or 16 ports)
• Power-failure relay protection for PRIs
• Connects local devices
• Additional redundancy options

The above two products come with up to 16 BRIs plus E1/T1 PRIs. For applications requiring more ports we can either cascade Liberators or look at the DB120 chassis.

All Liberator products are very flexible with the option to use advanced routing, number conversion and scheduling facilities; most are remotely upgradeable via ISDN; relay-protection is available between key interfaces; all are managed by a common, simple and intuitive Manager; all are simple to install and configure.

Thousands of Patapsco products are installed in Carrier and Corporate networks across the world.

In summary, Liberator can help connect video conference units to different types of ISDN, share services and inter-connect them.
