In many countries, customers can choose between competitive or Alternate Carriers for G.703/4 circuits, and perhaps PRI ISDN. But providing the services from the Carrier’s nearest Point-of-Presence (PoP) is expensive because they rent circuits from the main incumbent Carrier. These costs can limit the choice to customers, and restrict competition.
Now multiple services, including Fractional E1, PRI and BRI can be economically delivered over a single cable or circuit using Liberator.

Installing Liberator at the customer site means PRI, Fraction E1 and BRI can all be economically delivered over a single G.703 leased line.
Liberator looks like a PRI device to the new Carrier’s PoP equipment and provides the Alternate Carrier with the ability to monitor, manage and optimise the service to its new customers.

This illustration shows Liberators located at the Customer Premises and the Carrier’s PoP or exchange location.
They split the rented E1 G.703 leased line (which the pair of Liberators channelise and turn into a switched trunk), between the Carrier’s Switched Network and a separate Non-Switched Network. has more information.
