Summary

This article shows how to configure a board number with a SX2 ISDN board.

Please note: The use of this configuration option is not supported if you use a HST ISDN board simultaneously in your system.


Information

Each SX2 ISDN board a board number can be assigned to. This number is used to control the enumeration of CAPI controller numbers. A board number can be in the range from 1 up to 15. On a SX2 QuadBRI this range is from 1 up to 7. The assignment of CAPI controller numbers starts with the board having the lowest board number and continues with a board with the next higher board number.

Please make sure that you either assign a board number for all boards in the system or configure all boards for automatic number assignment.

If you configure a range of board numbers which is not coherent (e.g. 1,3,4 rather than 1,2,3) then non-configured boards are counted as a controller. Example: A SwyxGate system contains one SX2 QuadBRI with board number 1 and one SX2 SinglePRI with board number 3. The SX2 QuadBRI correspond to controller 1-4, while the non-existing board number 2 corresponds to a controller 5 which of course is not accessible. The SX2 SinglePRI board corresponds to controller number 6. You usually use this non-coherent board number assignment in a standby SwyxGate system.
