D.2 Connection of SwyxWare as Sub-telecommunication System on a Main Telecommunication System
SwyxWare can also be implemented as a sub-telecommunication system. An existing sub-telecommunication system is expanded but remains the main telecommunication system.
Fig. D-3: SwyxWare as sub-telecommunication system
In this case, the SX2 card is connected with the BRI/PRI connection of the main telecommunication system instead of with the PSTN.
Requirements
In the main telecommunication system, there must be an available BRI/PRI for the SwyxWare connection. In the SX2 card, the appropriate BRI/PRI must be available for the connection to the main telecommunication system.
The SX2 card that is used for the connection to the main telecommunication system must be configured in TE mode, i.e. as for the connection to the PSTN.
