PT-UP0 Extenders for ISDN 2
The Private Terminator (PT) is an ideal solution to realise extensions of ISDN 2 S0-Interfaces.
The PT is installed on the already existing ISDN 2 S0-Interfaces, without the need for any configurations.
The PT can also be installed as a converter between UP0– and S0-Interfaces.
PT as an Interface-Converter
The Interface-Conversion can be realised depending on the operational area:
- UP0 to S0 ISDN 2
Enables the connection of a S0-ISDN 2 interface over UP0-Interface, e. g. on telecommunicatios switch.
(Behaves as an NT, compares to e. g. NTBA of the Telecom) - S0 ISDN 2 to UP0
- Enable the connection of End devices with UP0-Interface on S0-Bus.
(Behaves as an inversed NT)
PT as a Repeater
To bridge extremely large distances, the PT can be used as a repeater.
- S0-UP0 repeater
Here the PT-SUP can be used to connect a NT1 or NT2 over a 2 Wire Line on the S0-Bus over a long distance. - UP0-S0 Repeater
This option is identical as the UP0-S0 Interface-Conversion.
The Private Terminator can also be used for the conversion of existing ISDN-Interfaces.
S0 to UP0
The PT-SUP enables the connection of end devices with UP0-Interface to an already existing S0-Bus.
UP0 to S0
The PT-UPS enables the connection of End Devices with S0-Interfaces to an already existing UP0-Interface e. g. from a PABX.

Further models of PTs (e.g. power supply by remote supply and/or mains power) are available on request.

Range extension over double copper wire for up to 3.5 km
With the use of PT the range of a S0-Interface can be extended up to 3.5 km with the use of a double copper cable.
The PT is housed in a compact housing with an integrated power supply.
The installation is by western connectors to the UP0– and S0-Interfaces and the PT is then connected to the mains supply by use of the 2 pin plug.
The PT convinces by simple handling and reliability.
