BOARD MANAGEMENT
PLUGGING IN A BOARD
When a board is plugged in, the system allocates numbers to the board equipment (subscriber direc-
tory numbers or line numbers); these numbers are allocated in ascending order of free system num-
bers. The board equipment is initialized with the corresponding default configuration.
When a board is plugged into a slot previously taken up by another board, this board is managed in
the following way:
- if the new board is of the same type (same scan point) as the board previously plugged in, the new
board is assigned the same data (numbers and configuration) as the previous one
- if the new board is different from the previous one, the system deletes the previous board and as-
sociated data (the numbers allocated are now available and the default configuration is cancelled).
The new board is then recognized as if it was plugged into a free slot (the equipment numbers are
allocated in ascending order and the board initialized with the default configuration corresponding
to the new board type).
UNPLUGGING A BOARD
The system should always be powered down before unplugging a board.
In general, unplugging a board from the module does not trigger an update of the data allocated to
the board (directory numbers, key programming, line parameters, etc) ; the unplugged board is con-
sidered as "absent and accepted" (it is taken into account when the system checks the equipment limits)
as long as no other board is plugged into this slot or a cold reset carried out on the system.
ALLOCATING DIRECTORY NUMBERS
When the system is booted, the directory numbers are assigned to the internal and virtual terminals on
the basis of the default numbering plan, in the following order of appearance of interface boards and
connected terminals:
- terminals connected to the SLI and UAI boards of the basic module
- terminals connected to the SLI and UAI boards of the add-on modules (if fitted)
- virtual terminals (XRA, DECT handsets, VMU, IP).
At the end of the system boot, the following numbers are assigned to the set options in order of ap-
pearance.
