A manufacturers switch/PABX delivers a UP0-Interface where an ISDN End device which has a BRI-Interface should be connected.
The use of the PT-UPS enables the conversion of the existing UP0 -Interface into a BRI-Interface. Herewith the ISDN End device can be connected to a Switch/PABX that is up to 3.5 km away.
The PT-UPS is connected via the the Up0 interface to the switch. The S0 connection of the ISDN End device is then connected to the PT-UpS. The PT-UpS is then plugged into the mains power supply and the unit is then installed. No configuration or programming is required.
