Select the protocol for each ISDN interface according to its application and the ISDN connection type: Point-to-multipoint and point-to-point connections can be used in various combinations at a LANCOM VoIP Router. The following options are available:
- Automatic for automatic selection of the operating mode (only in TE mode)
- DSS1 TE (Euro ISDN) for connection to a point-to-multipoint ISDN bus.
- DSS1 TE point-to-point for connection to a point-to-point ISDN bus.
- 1TR6 TE (German ISDN) for connection an ISDN bus which uses this protocol (in Germany only).
- DSS1 NT (Euro ISDN) to provide point-to-multipoint ISDN interfaces
- DSS1 NT reverse to provide point-to-multipoint interfaces while maintaining the ISDN timing of the connected ISDN line, please refer to
- DSS1 NT (point-to-point) to provide point-to-point ISDN interfaces
- DSS1 NT point-to-point reverse to provide point-to-point interfaces while maintaining the ISDN timing of the connected ISDN line, please refer to
- DSS1 timing to maintain the ISDN timing of the connected ISDN line, please refer to

Note: NT mode operation always has to be set manually.
Note: If an ISDN device is attached to an ISDN interface that is set
