Base Station Numbering
Base Stations are identified by hexadecimal numbers 08-FF which are referred to as Base Station
numbers or Base Station identities. A range of eight hexadecimal numbers is assigned to the
CLCs of a SLU/CLU when you add the first Base Station to it by means of the CSM software
command Base Station–Add. When you add the first Base Station to another SLU/CLU the next
free eight hexadecimal numbers are assigned to its CLCs. The first SLU/CLU receives 08-0F, the
next SLU/CLU that has a Base Station added will be 10-17. The Base Station assigns Base
Station numbers according to the CLC it is physically connected to. CLC 1 correlates to Base
Station number 08, or 10, etc.
The hexadecimal numbers 00 to 07 are not used. Therefore the hexadecimal numbers 08 to 0F
will be assigned to the first SLU/CLU used to add the first Base Station. Base Station numbering is
08-FF.
Given below is an example:
1.
When you define the first Base Station of the first SLU/CLU, its CLCs (1 to 8) will get Base
Station numbers 08 to 0F (hexadecimal).
2. When you define the first Base Station of the second SLU/CLU, its CLCs (1 to 8) will get Base
Station numbers 10 to 17 (hexadecimal).
3. When you define the first Base Station of the third SLU/CLU, its CLCs (1 to 8) will get Base
Station numbers 18 to 1F, etc.
If a SLU/CLU board is removed by the CSMW "Remove Board" command, a gap of 8 Base Station
numbers may arise. When there is a gap in the numbering, and the first Base station is added to
another SLU/CLU, the numbering system described above is used; the numbers in the gap are not
used. If in such a situation all Base Station numbers are used (08 – FF), the Base Station numbers
of the oldest ”gap” are used.
Note that if there are gaps in the Base Station numbers, the Base Station numbers will shift after a
system reset. If, for example, the second SLU/CLU is removed, then after a system reset the
numbers are:
z The CLCs of the first SLU/CLU still have Base Station numbers 08 to 0F
z The CLCs of the third SLU/CLU now have Base Station numbers 10 to 17, etc.
