In LANconfig, parameters for the ISDN interfaces are entered in the configuration section 'Interfaces' under 'WAN'. In WEBconfig, Telnet or an SSH client you find the settings for the ISDN interface parameters under Setup/Interfaces/WAN.
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 with 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.
- 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.
- DSS1 timing to maintain the ISDN timing of the connected ISDN line.
- Off
Note: If an ISDN device is attached to an ISDN interface that is set to auto and is not recognized properly, set the required protocol manually.
