ZXSDR R8862 Product Description
2.2 Software StructureFigure 2-2 illustrates the software structure of the ZXSDR R8862.
Figure 2-2 Software Structure
The software system of the ZXSDR R8862 runs on a Linux operating system that isinstalled on the hardware platform. The BSP, containing a suite of software closelyrelated to boards, supports the running of RTOS on the boards.
The operation supporting layer of the software system consists of six subsystems:
l OSS is a supporting layer for the entire software. It provides a hardware-irrelevantplatform on which the software runs to provide basic functions, such as scheduling,timing, memory management, inter-module communication, sequence control,monitoring, alarm management, , and log management.
l SCS controls the power supply and active/standby switchover.l OAM provides configuration, fault management, and performance measurement
functions.l DBS stores and manages data in the system.l BRS processes protocols in the system.l BRACS controls access to the bearer layer.

3.2 Operation and Maintenance FunctionsThe NetNumen U31 unified element management system provides a GUI that displaysthe information of all NEs in the entire network on a topology map. A user can viewperformance data, alarm information, and configuration data of a specific NE, or operateand maintain multiple NEs of the same type on the topology map.
The NetNumen U31 provides the following operation and maintenance functions:
l Configuration management
The configuration management supports dynamic and static configuration of basestations, such as the addition, query, deletion, modification, and data consistencycheck of physical and radio resources.
l Security management
The security management ensures that only authorized users can perform permittedoperations on base stations.
l Performance management
The performance management supports performance analysis, calling trace, andsignaling trace.
l Version management
