4.2.4.2.3. C̲o̲m̲m̲a̲n̲d̲ ̲C̲o̲n̲t̲r̲o̲l̲ ̲M̲o̲d̲u̲l̲e̲ ̲(̲3̲.̲0̲)̲
The Command Control Module is responsible for handling
of all commands except the timer command. The structure
of this module is depicted n figure 4.2.4.2-2.
The command itself forms the basis for a sequence of
case structures, all associated to specific functions
whichin combination shall be performed.
The module performs the following processing:
a) Determines if the command s a Start-up.
If so, it will activate the start-up Module (3.1)
which in accordance with a subcommand indicating
the nature of start-up will activate the proper
sequence of modules relevant for that type of start-up.
b) If any parameters shallbe updated the Parameter
update module (3.2) will be called.
It will maintain counters and flags on basis of
the command-type.
- Set Channel Open
- Set Channel Close
- Reset TSN
- Reset Timer
- Set Preemption
In accordance with rest of timer the entry in the
Time-out Table will first be calculated. For the
Set Preemption, it will first be calculated, whether
preemption shall take place or not.
c) If the command directly or indirectly applies for
automatic generation of an SM, this will be done
via a Generate ASM Case structure with the following
separate modules:
- Generate Channel Open Module (3.3.1)
- Generate Channel Close Module (3.3.2)
- Generate Channel Continuity Module (3.3.3)
- Generate Self-addresed Channel Check Module
(3.3.4)
