One of Liberator's capabilities is to use multiple low-cost BRI lines to present one or more PRIs to your local equipment.
Other conversion configurations are available using PRI and BRI ports and these can be seen in overview on the Connectivity Diagram page.

This illustration shows two local PRI devices sharing network access via multiple BRI ports and the further optional ability for local BRIs to also share and contend for access.

Many CPEs which need multiple “B” channel access require PRI
connectivity. But often the PRI is:

• Not available
• Not delivered as a part-populated PRI so all 30 channels must be rented even if less are needed
• Very expensive in terms of installation, rentals and possibly deposits

Liberator can:

• Reduce ISDN installation and rental costs
• Enable applications and the use of CPE which would not otherwise be viable
• Supply only as much network capacity is required
• Be easily expandable to add capacity when needed
• Support up to 16 BRI lines (32 “B” channels)
• Support multiple PRIs and local BRIs

• Provides two DTEs or CPE with fractional PRIs.
• Ability to share and contend for access if required.
• Local BRI devices can also share access to the network.
• Reduce ISDN rental, installation and deposit costs.
• Liberator supports up to 16 BRIs.
