The five layers from the top downward are as follows:
1. Hardware
The physical platform on which the CMM software is running.
2. BSP (board-level support package)
BSP initializes CMM boards and provides drivers for the relevant parts
of the equipment. It provides consistent operation interfaces for the
specific details of the upper-level encapsulated hardware equipment
and simplifies the OSS design.
3. pSOS + operating system
It is a real-time multi-task operating system for commercial purposes
and with superior performance. The operating system has been
successfully applied to the next-generation BTS.
4. Operation support system (OSS) layer
This layer consists of the following parts:
i. RUNSPT
It is the core layer of the OSS.
It is a dispatch system of the state machine, providing process
