The board board is configured like a Ring Generator (RG) and is plugged
in a peripheral slot of the OpenScape 4000. It only gets power from the
OpenScape 4000 switch. No direct signalling and administration is supported.
The connection to OpenScape 4000 is done via a separate DIUS2 board.
In this configuration the board is loaded and administrated via V.24
interface from a separate PC (CDGM-Tool).
This configuration only uses one circuit of the PBXXX i.e. 30 B channels
