RGUS 125
18 Connection to a PRI Network
Since there is no commonly accepted standard for the connections in the 2 Mbit sector, you
will be confronted with different forms of connectors depending on the type of terminal and
the network termination used.
The ARGUS changes the connector pin assignments automatically in accordance with the
mode, TE or NT. Additionally, it is also possible to change the pin assignments manually in
the L1-Status menu.
18.1 Connector Pin Assignments on the ARGUS 125 (Line)
In TE mode, the ARGUS sends on lines 4 and 5, in NT-Mode on 1 and 2 (see illustration).
An adapter cable, which is suitable for the respective ISDN network/system, can be
connected using the RJ45-RJ45 adapter.
