PT SU/US

PT-U0 Range extension for the BRI-Interfaces

The PT is the ideal solution to extend the range of BRI ISDN-Interfaces. The PT is connected to the already existing BRI ISDN-Interfaces and there is no requirement for any further configuration. The PT can also be used as a converter between U0– and BRI ISDN-Interfaces.

The PT can realise the following expendabilities in the ISDN:

PT as an Interface-Converter

The conversion of interfaces can be realized depending upon operational area as follows:

  1. U0 to BRI
    Allows the connection of a S0-Bus over an U0-Interface, e. g. on a Telecom’s Switch.
    (Behaves as an NT, equal to an e. g. NTBA from Telecom)
  2. BRI to U0
    Allows the connection of End user equipment U0-Interface to the BRI-Bus.
    (Behaves like an inverse NT)

PT as a Repeater

In order to be able to bridge particularly large distances, the PT can be used as a Repeater.

  1. BRI-U0 Repeater
    Here the PT-SU allows the connection of a distant terminal set over a 2-Wire cable to the BRI-Bus of a NT1 or a NT2.
  2. U0-BRI Repeater
    With this option the application is identical to the U0-BRI conversion of an interface.
  3. U0-U0 Repeater
    To allow the extension of extremely high distances (12 km and more) over a 2-Wire connection, e. g. transverse transmission between two Telecoms switches (see also for this the description for the PT-Repeater )

Range Extension over a 2 Wire Cable for up to 8 km

By means of the private terminator PT the range of a BRI-Interface can be increased up to 8 km by means of a 2-Wire Line cable.

The Private Terminator PT is mounted in a compact housing with integrated power supply.

The installation is by means of Western Connectors, the U0 and BRI-Interfaces are connected, and  the PT is plugged into the wall power socket.

The private terminator PT convinces by simple handling and reliability.

For more information please consult the handbook, which is provided for download. Other types of PTs (e.g. current supply by remote supply and/or further power supplies) are available on request.

Proofed and certified quality

The private terminator PT can be operated with any PABX providing the valid and certified interfaces and which is being available and in operation in the market. AGFEO has performed compatibility tests with the PT on their own. The compatibility and thus the unrestricted usage of the PT has been determined and testified.
