6-9 MINI-LINK BAS
EN/LZB 111 0542 P2B Technical Description
6.4 EM
The functionality of the EM is implemented by means of a number of
applications, each handling a specific management area. Some
applications also provide GUI, through which an operator can manage
resources in the NEs.
Applications are based on the OTP and HP-OV NNM platforms.
These are widely used platforms for telecom application, also
providing support for fault, configuration and performance
management.
In general, the EM software may be seen as layered in three levels.
This architecture allows the system to be very flexible: modules at a
given level require functionality to modules at the level below it. This
also allows adding new applications on top of the current architecture
without changing the lower layers.
Figure 6-5 depicts the internal software architecture of the EM.
